Hepatoprotective drugs for the treatment of virus-induced chronic

Interferon (IFN)-based therapy is a standard treatment for chronic
hepatitis caused by hepatitis C virus (HCV) infection. This treatment is
effective in approximately 30-40% of the patients and using ribavirin in
combination with IFN increases the rate of sustained virologic
clearance. For the remaining patients, glycyrrhizin is often used.
Glycyrrhizin is known to prevent the development of hepatocellular
carcinoma (HCC), but glycyrrhizin is usually administered intravenously.
Drugs that are effective by oral administration are convenient for
patients for long-term administration, and development of more effective
drugs than glycyrrhizin is preferable. However, studies on drugs for the
treatment of hepatitis are not actively conducted, and promotion of the
study of drugs in this area is encouraging. For that reason, we show our
approach to study drugs for the treatment of hepatitis. We analyzed the
effect of glycyrrhizin on hepatitis as a standard chemical using the
mouse liver injury model. Based on this, we screened drugs and found
that a coumarin derivative seems to be one of model chemicals for the
treatment of hepatitis.

Post-treatment malignant liver lesions. MR imaging.

AD - Department of Radiology, University of North Carolina School of
Medicine, Chapel Hill, North Carolina, USA.
MR imaging is very accurate in the diagnosis and staging of tumors and
in surgical planning. MR imaging is also an excellent method for
evaluation of the liver after surgical resection, systemic or local
tumor therapies, and liver transplantation. It permits early recognition
of complications and the presence of recurrent tumor, providing an
opportunity to repeat treatment or use alternative treatment. Surgical
resection remains the standard therapy for treating liver metastases.
The relatively small number of patients who are candidates for curative
resection have provided impetus for the implementation and improvement
of other techniques. The variety of techniques and the sensitivity for
contrast enhancement have made MR imaging an ideal method to follow the
response of tumors to various treatment approaches. The appearance of
tumor recurrence and the response to treatment are relatively
consistently shown on MR images; however, the time course of change in
lesion appearance has not been fully elucidated, particularly in the
setting of chemotherapy. Evaluating the response to chemotherapy is
rendered complex because of the longer duration of the therapy, the
types of response that various chemotherapeutic agents engender, the
method of action of this therapy and the time of imaging in relation to
therapy. The various local therapies share some general principles of
action, and many have similar MR imaging findings. Some local therapies
are effective only with certain malignancies (e.g., alcohol therapy and
HCC), whereas other therapies are more limited because of the size of
the tumor kill zone (e.g., interstitial laser therapy). We are in the
early stages of using MR imaging to guide local therapies and to monitor
response during treatment in real time. This appears to be an important
future direction for MR imaging. The role of MR imaging in liver
transplantation involves pre- and postoperative investigation of both
donors (in the case of living-related transplantation) and recipients.
These issues are described further in the section on MR imaging of liver
transplantation.

Resection of hepatocellular carcinoma without preoperative tumor biopsy.
SO - Ann Surg 2001 Aug;234(2):206-9
AD - Department of Medicine, Toronto General Hospital, Toronto, Canada.
OBJECTIVE: To evaluate the need for a preoperative tumor biopsy of liver
lesions suspicious for hepatocellular carcinoma (HCC). SUMMARY
BACKGROUND DATA: With advances in liver imaging, the results of recent
studies have suggested a very high accuracy of preoperative evaluation
of liver masses suspicious of HCC, making preoperative tumor biopsy
unnecessary. METHODS: A retrospective analysis was conducted of all
liver resections for HCC at the Toronto General and Mt. Sinai Hospitals,
underwent 65 liver resections without a preoperative liver biopsy. The
median age was 61 years. Sixty percent of the patients had cirrhosis and
38.5% had noncirrhotic chronic hepatitis. HCC was confirmed
histologically in the surgical specimen in 63 of the 65 cases (96.9%).
Both patients without HCC had a significant risk factor for HCC (chronic
hepatitis C and alcohol in one and chronic hepatitis B and previous
resection for HCC in the other). The lesions were 2 cm and 2.7 cm in
diameter, and the alpha-fetoprotein level was low (<5 and 22 ng/mL,
respectively). In such patients, with tumor 3 cm or smaller and an
alpha-fetoprotein level less than 100 ng/mL (10 patients), the
false-positive rate for the preoperative diagnosis was 2/10 (20%).
CONCLUSIONS: Preoperative diagnosis of HCC was highly accurate in
lesions larger than 3 cm. Tumor biopsy is unnecessary in these patients.
However, in a subgroup of patients with lesions less than 3 cm,
particularly those with alpha-fetoprotein levels less than 100 ng/mL,
there is a higher false-positive diagnostic rate, and tumor biopsy
should be considered.

Intrahepatic cholangiocarcinoma: resectability, recurrence pattern, and
outcomes.
SO - J Am Coll Surg 2001 Oct;193(4):384-91
AD - Hepatobiliary Service, Memorial Sloan-Kettering Cancer Center, New York,
NY, USA.
Intrahepatic cholangiocarcinoma (IHC) is a rare primary hepatic tumor of
bile duct origin for which resection is the most effective treatment.
But resectability, outcomes after resection, and recurrence patterns
have not been well described. Patients with IHC were identified from a
prospective database. Demographic data, tumor characteristics, and
with hepatic tumors underwent exploration and were found to have pure
IHC on pathologic analysis. Patients with mixed hepatocellular and
cholangiocarcinoma tumors were excluded. At exploration, 20 patients
were unresectable for an overall resectability rate of 62% (33 of 53).
Median survival for patients submitted to resection was 37.4 months
versus 11.6 months for patients undergoing biopsy only (p = 0.006;
median followup for surviving patients, 15.6 months). Actuarial 3-year
survival was 55% versus 21%, respectively. Factors predictive of poor
survival after resection included vascular invasion (p = 0.0007),
histologically positive margin (p = 0.009), or multiple tumors (p =
0.003). After resection, 20 of 33 patients (61%) recurred at a median of
12.4 months. Sites of recurrence included the liver (14),
retroperitoneal or hilar nodes (4), lung (4), and bone (2). The median
disease-free survival was 19.4 months, with a 3-year disease-free
survival rate of 22%. Factors predictive of recurrence were multiple
tumors (p = 0.0002), tumor size (p = 0.001), and vascular invasion (p =
0.01). About two-thirds of patients who appeared resectable on
preoperative imaging were amenable to curative resection at the time of
operation. Although complete resection improved survival, recurrence was
common. The majority of recurrences were local or regional, which may
help guide future adjuvant therapy strategies.

[Extrahepatic arterial blood supply of hepatocellular carcinoma and
interventional treatment]

Academy of Medical Sciences, Peking Union Medical College, Beijing
100021, China.
OBJECTIVE: To study the pattern extrahepatic arteriy supply to
hepatocellular carcinoma and catheterization technique for
interventional therapy. METHODS: Routine celiac and superior mesenteric
artery angiography was done before transcatheter arterial
chemoembolization (TACE) for 78 collateral arterial pathways of 62
hepatocellular carcinoma patients. Super selective catheterization and
transcatheter dual arterial chemoembolization (TDACE) to extrahepatic
arterial and hepatic arteries were performed. RESULTS: Extrahepatic
blood supply was found in 43.1% of hepatocellular carcinoma patients.
There was close correlation between extrahepatic arterial blood supply
and location of tumor. Success rate of super selective extrahepatic
artery catheterization was 71.8% by the combined use of RH, Cobra and SP
catheters. Follow-up studies revealed reduction of tumor and complete
dense deposition of lipiodol. CONCLUSION: Ample extrahepatic arterial
blood supply is found in hepatocellular carcinoma. Transcatherdual
arterial chemoembolization is effective, necessary and feasible for
hepatocellular carcinoma with extrahepatic arterial blood supply.

hepatocellular carcinoma]
SO - Zhonghua Wai Ke Za Zhi 2002 May;40(5):329-31
AD - Eastern Hepatobiliary Surgery Hospital, Second Military Medical
University, Shanghai 200438, China.
OBJECTIVE: To evaluate postoperative transcatheter hepatic arterial
chemoembolization (TACE) for improving the disease-free survival of HCC
patients after hepatectomy. METHODS: 1 725 HCC patients were followed up
after hepatectomy retrospectively. Of 1 457 patients who were
followed-up completely, 209 had postoperative TACE. The 1 457 patients
were divided into ten groups according to tumor thrombus, small HCC,
capsular invasion, vascular invasion and cirrhosis. The disease-free
survival was analyzed between subgroups of weather postoperative TACE
was performed in every group. Software SAS 6.12 and EGRET package were
used. Kaplan-Meier estimation was used to calculate the disease-free
survival rates. RESULTS: There were no difference of the disease-free
survival between the subgroups in no capsular invasion and in no hepatic
cirrhosis groups. CONCLUSION: Postoperative TACE is helpful in improving
the disease-free survival of HCC patients after hepatectomy except those
with integrated tumor envelope or no hepatocirrhosis. It is important to
prolong the long-term results of operation.

AD - Department of Radiology, Samsung Medical Center, Sungkyunkwan University
School of Medicine, 50, Ilwon-Dong, Kangnam-Ku, Seoul 135-710, Korea.
OBJECTIVE: The purpose of our study was to compare the diagnostic
accuracy and lesion conspicuity of ferumoxides-enhanced MR imaging with
those of mangafodipir trisodium-enhanced MR imaging for the preoperative
detection of hepatocellular carcinoma. SUBJECTS AND METHODS: Twenty-one
patients with 39 hepatocellular carcinomas underwent
ferumoxides-enhanced and mangafodipir trisodium-enhanced MR imaging. The
diagnosis was established by pathologic examination after surgical
resection in all patients. Five MR sequences were obtained 30 min after
ferumoxides administration, and two MR sequences were obtained before
and 15 min after mangafodipir trisodium administration. Three observers
independently interpreted both MR images of all sequences on a
segment-by-segment basis. The diagnostic accuracy of MR imaging was
assessed using receiver operating characterizing analysis. Lesion
(hepatocellular carcinoma > 10 mm in diameter)-to-liver
contrast-to-noise ratio was calculated on MR images. RESULTS:
Ferumoxides-enhanced MR imaging (A(z) = 0.971) was significantly more
accurate (p < 0.05) than mangafodipir trisodium-enhanced MR imaging
(A(z) = 0.950). The mean sensitivity of ferumoxides-enhanced MR imaging
(86%) was significantly greater (p < 0.05) than that of mangafodipir
trisodium-enhanced MR imaging (44%) in lesions smaller than 10 mm. The
mean lesion-to-liver contrast-to-noise ratio of hepatocellular carcinoma
on ferumoxides-enhanced MR imaging (13.7 +/- 8.8) was significantly
greater than on mangafodipir trisodium-enhanced MR imaging (5.4 +/- 5.1)
(p < 0.01). CONCLUSION: Ferumoxides-enhanced MR imaging has superior
diagnostic accuracy in lesions smaller than 10 mm and superior lesion
conspicuity compared with mangafodipir trisodium-enhanced MR imaging for
the preoperative detection of hepatocellular carcinoma.

Allocation of cadaveric livers to patients based on such objective
medical urgency data as the Model for End-Stage Liver Disease (MELD)
score may not benefit patients with small hepatocellular carcinomas
(HCCs). To ensure that these patients have a fair opportunity of
receiving a cadaveric organ, the risk for death caused by HCC and tumor
progression beyond 5 cm should be considered. Using a Markov model, two
hypothetical cohorts of patients with small hepatomas were assumed to
have either (1) Gompertzian tumor growth, in which initial exponential
growth decreases as tumor size increases; or (2) rapid exponential
growth. The model tracked the number of patients who either died or had
tumor progression beyond 5 cm. These results were used to back-calculate
an equivalent MELD score for patients with small HCCs. All probabilities
in the model were varied simultaneously using a Monte Carlo simulation.
The Gompertzian growth model predicted that patients with a 1- and 4-cm
tumor have 1-year progression-free survival rates of 70% (HCC-specific
MELD score 6) and 66% (HCC-specific MELD score 8), respectively. When
assuming rapid exponential growth, patients with a 1- and 4-cm tumor
have progression-free survival rates of 69% (HCC-specific MELD score 6)
and 12% (HCC-specific MELD score 24), respectively. Our model predicted
that the risk for death caused by HCC or tumor progression beyond 5 cm
should increase with larger initial tumor size in patients with small
hepatomas. To ensure that these patients have a fair opportunity to
receive a cadaveric organ, HCC-specific scores predicted by our model
could be added to MELD scores of patients with HCC.

PRECIS: Intraarterial delivery of 50 mg/m2 cisplatinum on a monthly
basis is a well-tolerated regimen for patients with nonresectable
hepatoma. The selective uptake of cisplatinum delivered intraarterially
suggests other selective intraarterial protocols would be of use in
regional cancers treated with cisplatinum. BACKGROUND: Sixty-seven
patients with nonresectable hepatoma were treated with hepatic artery
infusions (HAI) of 50 mg/m2 cisplatinum on a monthly basis. METHODS:
Forty-eight patients received an initial course of whole liver external
radiation with intravenous (i.v.) cisplatinum 50 mg/m2. Nineteen
patients did not receive radiation and received HAI cisplatinum only.
All patients then received HAI cisplatinum at 50 mg/m2 on a monthly
basis. Six patients were given a tracer dose of radioactive 195m
cisplatinum for quantitation by the HAI and i.v. routes. RESULTS:
Monthly HAI cisplatinum was well tolerated and could be repeated
indefinitely. Median survival for primarily treated nonresectable
hepatomas was 12 months [alpha fetoprotein (AFP) elevated] and 17.5
months (AFP negative). Radioactive cisplatinum given by HAI yielded
34-55% tumor uptake of cisplatinum vs. < 5% by i.v. delivery.
CONCLUSIONS: Hepatic intraarterial cisplatinum at 50 mg/m2 is a
well-tolerated monthly regimen for patients with nonresectable hepatoma.

Prospective assessment of the safety and benefit of laparoscopic liver
resections.
SO - J Hepatobiliary Pancreat Surg 2002;9(2):242-8
AD - Department of Digestive Surgery and Liver Transplantation, Beaujon
Hospital, 92118 Clichy cedex, France.
BACKGROUND/PURPOSE: Laparoscopy represents an alternative to open
surgery for virtually all digestive surgery procedures, with the
anticipated short-term advantage of reduced esthetic prejudice,
postoperative pain, and duration of in-hospital stay. In this study, we
investigated the safety and benefits of laparoscopic liver resections in
patients with benign solid liver tumors. METHODS: Laparoscopic liver
resection of up to two segments for benign liver tumor was performed
under continuous carbon dioxide (CO(2)) pneumoperitoneum in 21 patients
with no underlying chronic liver disease. The risk of gas embolism was
assessed by end-tidal CO(2) and O(2) saturation, and the hemodynamic
variations were monitored by a Swan-Ganz catheter. The postoperative
course was compared with that following open surgery by matched-pair
analysis. RESULTS: No patient experienced gas embolism or was converted,
and clamping of the hepatic pedicle resulted in hemodynamic variations
comparable to those observed during open surgery. Duration of surgery
(177 vs 156 min.), intraoperative blood loss (218 vs 285 ml),
modifications of postoperative liver function tests, and incidence of
postoperative complications (10% vs 10%) were comparable to those after
open surgery. Laparoscopic resection was associated with a 50% reduction
(15.5 vs 31.6 mg) in morphine consumption during the first postoperative
days, a reduction of the delay to oral intake of 0.8 days, and a
reduction of in-hospital stay of 1.4 days. CONCLUSIONS: Liver resections
of up to two segments can be performed by laparoscopy using the same
technique as that used during open surgery. However, the benefits
observed compared with open surgery appear to be limited.

Radiofrequency ablation of hepatocellular carcinoma.

scurley@mdanderson.org
The majority of patients with primary or metastatic hepatic tumors are
not candidates for resection because of tumor size, location near major
intrahepatic blood vessels precluding a margin-negative resection,
multifocality, or inadequate hepatic function related to coexistent
cirrhosis. Radiofrequency ablation (RFA) is an evolving technology being
used to treat patients with unresectable primary and metastatic hepatic
cancers. RFA produces coagulative necrosis of tumor through local tissue
heating. Liver tumors are treated percutaneously, laparoscopically, or
during laparotomy using ultrasonography to identify tumors and to guide
placement of the RFA needle electrode. For tumors smaller than 2.0 cm in
diameter, one or two deployments of the monopolar multiple array needle
electrode is sufficient to produce complete coagulative necrosis of the
tumor. However, with increasing size of the tumor, there is a
concomitant increase in the number of deployments of the needle
electrode and the overall time necessary to produce complete coagulative
necrosis of the tumor. In general, RFA is a safe, well-tolerated,
effective treatment for unresectable hepatic malignancies less than 6.0
cm in diameter. Effective treatment of larger tumors awaits the
development of more powerful, larger array monopolar and bipolar RFA
technologies.

Finite-element analysis of hepatic multiple probe radio-frequency
ablation.
SO - IEEE Trans Biomed Eng 2002 Aug;49(8):836-42
AD - Department of Surgery, University of Wisconsin, Madison 53792, USA.
Radio-frequency (RF) ablation is an important means of treatment of
nonresectable primary and metastatic liver tumors. RF ablation, unlike
cryoablation (a method of tumor destruction that utilizes cold rather
than heat), must be performed with a single probe placed serially. The
ablation of any but the smallest tumor requires the use of multiple
overlapping treatment zones. We evaluated the performance of a
configuration incorporating two hooked probes (RITA model 30). The
probes were lined up along the same axis in parallel 20 mm apart. Three
different modes applied voltage to the probes. The first mode applied
energy in monopolar mode (current flows from both probes to a dispersive
electrode). The second mode applied the energy to the probes in bipolar
mode (current flows from one probe to the other). The third method
applied the energy sequentially in monopolar mode (in 2-s intervals
switched between the probes). We used the finite-element method (FEM)
and analyzed the electric potential profile and the temperature
distribution at the end of simulation of a 12-min ablation. The
alternating monopolar mode allowed precise independent control of the
amount of energy deposited at each probe. The bipolar mode created the
highest temperature in the area between the probes in the configuration
we examined. The monopolar mode showed the worst performance since the
two probes in close vicinity create a disadvantageous electric field
configuration. We, thus, conclude that alternating monopolar RF ablation
is superior to the other two methods.

IkappaBalpha gene therapy in tumor necrosis factor-alpha- and
chemotherapy-mediated apoptosis of hepatocellular carcinomas.
SO - Cancer Gene Ther 2000 Oct;7(10):1315-23
AD - Department of Gastroenterology and Hepatology, Medizinische Hochschule
Hannover, Germany.
The transcription factor nuclear factor kappaB (NFkappaB) is an
essential antagonist of apoptosis during liver regeneration and
embryonal development of hepatocytes. Several reports have indicated
that NFkappaB may also inhibit the programmed cell death induced by
cytokines, ionizing radiation, or cytotoxic drugs in some cancer cell
lines. Because hepatocellular carcinomas (HCCs) are one of the most
resistant tumors to systemic chemotherapy, we investigated the
activation of NFkappaB and the consequence of its inhibition by an
IkappaBalpha-super repressor during tumor necrosis factor alpha
(TNFalpha)- and chemotherapy-induced apoptosis in HCC cell lines. We
demonstrate that both TNFalpha and adriamycin activate NFkappaB in
hepatoma cells. Activation of NFkappaB could be blocked through an
adenoviral vector expressing the IkappaBalpha super repressor,
regardless of the activating agent. Inhibition of NFkappaB enhanced the
apoptosis induced by TNFalpha, whereas IkappaBalpha had an
anti-apoptotic effect on chemotherapy-induced programmed cell death. A
strong inhibition of chemotherapy- and TNFalpha-induced apoptosis by
dominant-negative Fas-associated death domain indicated an essential
contribution of death receptor-mediated apoptosis. To elucidate the
different role of NFkappaB in chemotherapy-induced apoptosis, we
investigated the expression of Fas (CD95) and Fas ligand (CD95 ligand),
which have been described as important mediators of chemotherapy-induced
cell death and as target genes of NFkappaB. However, our investigations
demonstrated that in hepatoma cells, the chemotherapy-induced
up-regulation of Fas (CD95) and Fas ligand (CD95 ligand) is not
transcriptionally mediated through NFkappaB. Thus, other molecular
mechanisms must account for the anti-apoptotic effect of IkappaBalpha in
adriamycin-induced death of hepatoma cells. In summary, our
investigations indicate that the activation of NFkappaB in response to
cytotoxic drugs, in contrast to TNFalpha, exerts a pro-apoptotic
stimulus rather than an anti-apoptotic function, which has implications
for therapy of HCCs.

Management of spontaneous bleeding due to hepatocellular carcinoma.

BACKGROUND: Spontaneous rupture is a life-threatening complication of
HCC, occurring in 4.8-26% of cases. Liver failure is the main cause of
death. Debates still remain on the most appropriate treatment in such
patients because of the high operative mortality of emergency surgery
and the high risk of rebleeding and less satisfying mid- and long-term
results of nonoperative procedures like angiographic embolization. Early
and long-term results of a surgically oriented treatment, based on
prompt evaluation of the functional liver reserve and tumor
(11.86 years) were treated for ruptured HCC, in 10 cases involving a
cirrhotic liver. Seven patients underwent emergency surgery and 4
patients transcutaneous arterial embolization (TAE). Liver resection was
performed in patients with preserved liver function, after
ultrasonography and/or CT scan demonstrated hemoperitoneum and a single
resectable liver tumour (5 cases). In one patient with cirrhosis,
ultrasonography showed only hemoperitoneum. A bleeding nodule was
discovered intraoperatively and resected in a liver with a multinodular
HCC. Another patient under-went emergency resection after referral at
our Unit with a surgical packing. In 4 cases with poor liver function
and/or unresectable tumour TAE of the neoplasm was performed, in one
case after surgical packing. Mortality, morbidity and patients survival
after treatment were analyzed. All patients had at least 1 year
follow-up. RESULTS: All patients underwent minor resection; 2 left
lobectomies, 1 segmentectomy (VII), 1 bisegmentectomy (VII-VIII), and 3
wedge resections. Postoperative course was complicated by ascites in 5
cases and subphrenic abscess in one case. Four patients died 3, 4, 6 and
62 months after surgery; 3 patients are actually alive 22, 25, and 89
months after surgery. Four patients were submitted to TAE: all patients
died within 6 months. CONCLUSIONS: When ruptured HCC is suspected,
preserved liver function (Child A-B7) and a resectable hepatic tumour
are considered clear indications to surgery. Emergency liver resection
achieved good early and long-term results. In cases of advanced liver
disease or multinodular HCC a non-operative approach, like TAE, must be
attempted. Surgical direct hemostasis or hepatic artery ligation must be
reserved for patients with uncontrollable o recurrent bleeding after
TAE.

Between 1995 and 1997 we studied 100 patients with hepatocarcinoma (HCC)
and cirrhosis. Of these 74 were males and 26 females with a mean age of
66 years. 13% patients were only HbsAg positive, 75% only anti-HCV
positive, 6% HbsAg and anti-HCV and the etiology in 6% of cases was
alcoholic. Alpha-foetoprotein was >400 ng/ml in only 18% of cases and
portal thrombosis was present in 12%. Mononodular HCC was observed in
63% of cases (small HCC in only 38%) and in 79% was localized to the
right lobe. Of the mononodular types, 70% were shown by echography to be
hypoechoic, 6% hysoechoic, 6% hyperechoic and 17% mixed patterns.
Histologically, 49% were well-differentiated, 45%
moderately-differentiated and 6% poorly-differentiated. No correlation
was found between histologic pattern and number of nodules.
Well-differentiated HCC was found in 51% of mononodular types and in 46%
of multinodular types. Moderately-differentiated HCC was detected in 46%
and 43% respectively and poorly-differentiated HCC in 3% and 11%
respectively. No correlation was found between number of nodules and the
degree of Edmonson.

BACKGROUND: In 1998, when data of a meta-analysis on tamoxifen in the
treatment of hepatocellular carcinoma (HCC) had suggested a little
advantage for this treatment, we published the results of a multicenter
randomised controlled trial, that showed no survival benefit for
tamoxifen vs. control. Here we report an updated analysis of the study
results 4.5 years after the closure of enrollment. METHODS: The study
had a planned sample size of 480 patients. Patients with any stage HCC
were eligible, irrespective of locoregional treatment. Tamoxifen was
given orally, 40 mg/die, from randomisation until death. RESULTS: 496
deaths (78%) were recorded, and median survival times were 16 and 15
months (p=0.54), in the control and tamoxifen arm. Data were further
analysed separately for advanced patients and for those eligible to
potentially curative locoregional treatments: relative hazard of death
for patients receiving tamoxifen was equal to 0.98 (95% CI 0.76-1.25)
for the former group and 1.38 (95% CI 0.95-2.01) for the latter. The
prognostic score recently devised by our group (CLIP score) was, as
expected, strictly correlated (p<0.0001) to the locoregional treatment
received and strongly correlated with prognosis. CONCLUSIONS: the update
of the present study confirms that tamoxifen is not effective in
prolonging survivals, both in advanced patients and in those potentially
curable and that the CLIP score is able to predict prognosis.

We examineded the clinical effects of serum hepatitis B e antigen
(HBeAg) positivity on clinicopathologic findings and prognosis after
liver resection for hepatocellular carcinoma (HCC) in patients with
chronic hepatitis B. A series of 56 patients who underwent curative
resection were divided into two groups: 25 HBeAg-positive patients
(group 1) and 31 HBeAg-negative patients (group 2). The mean age was
significantly lower in group 1 than in group 2 (p = 0.0021), and the
proportion of patients with symptoms was significantly higher in group 1
than in group 2 (p = 0.037). There were no significant differences in
other clinical findings between the two groups, including laboratory
test results, coexisting medical conditions, and operative methods.
Although tumor size, degree of differentiation of the main tumor, and
the prevalence of vascular invasion did not differ between the groups,
the prevalence of intrahepatic metastasis and the proportion of patients
with active hepatitis were significantly higher in group 1 than in group
2 (p = 0.009 and p = 0.043, respectively). Tumor-free and cumulative
survival rates were significantly lower in group 1 than in group 2 (p =
0.022 and p = 0.0001, respectively). Multivariate analysis of various
possible risk factors demonstrated serum HBeAg positivity to be an
independent risk factor for recurrence [risk ratio (RR) 2.49; 95%
confidence interval (CI) 1.12-5.49; p = 0.032] and an independent
unfavorable factor for the survival time (RR 7.58; 95% CI 2.10-27.8; p =
0.0020). We concluded that the prognosis after liver resection for HCC
is worse for HBeAg-positive patients than for HBeAg-negative patients.

Hepatocellular carcinoma in elderly patients: beneficial therapeutic
efficacy using percutaneous ethanol injection therapy.
SO - Cancer 2002 Aug 15;95(4):816-23

Tokyo, Japan. teratani-2im@h.u-tokyo.ac.jp
BACKGROUND: The age of patients with hepatocellular carcinoma (HCC) has
been increasing worldwide. The objective of this study was to assess the
efficacy and safety of percutaneous ethanol injection therapy (PEIT) in
elderly patients with HCC. METHODS: The authors retrospectively analyzed
653 patients who were treated with PEIT between 1985 and 1997. One
hundred thirty-seven patients were age > or = 70 years, 90 of 137
patients (66%) were male, and 106 of 137 patients (77%) were positive
for hepatitis C virus antibodies. Both survival rates and standardized
mortality ratios (SMRs) related to the causes of death were compared
between patients age > or = 70 years and patients age < 70 years.
RESULTS: With the exception of greater maximum tumor size in elderly
patients age > or = 70 years, the clinical features of tumors and
underlying liver disease were similar to those of patients age < 70
years The survival rates after PEIT in patients age > or = 70 years were
83%, 52%, and 27% at 1 year, 3 years, and 5 years, respectively. These
results were comparable to the rates for patients age < 70 years (1
year, 90%; 3 years, 65%; and 5 years, 40%). In addition, there was no
difference in mortality from extrahepatic disease between the two groups
(9.8% for patients age > or = 70 years vs. 9.4% for patients age < 70
years; P > 0.999). The SMR of patients age > or = 70 years who died of
causes related to extrahepatic disease (SMR, 0.56; 95% confidence
interval [95%CI], 0.18-1.30) was lower compared with the SMR of patients
age < 70 years (SMR, 1.75; 95%CI, 1.07-2.71). The SMR of patients age >
or = 70 years who died of causes related to liver disease (SMR, 115;
95%CI, 84.1-153.0) was similar to that of patients age < 70 years (SMR,
120; 95%CI, 103.0-138.0). CONCLUSIONS: These results provide support for
the treatment of patients with HCC age > or = 70 years by tumor ablation
using PEIT. Copyright 2002 American Cancer Society.DOI

Radiofrequency thermal ablation versus other interventions for
hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common
malignant diseases worldwide. The only possibly curative therapeutic
option is surgical resection. Due to impaired liver function and/or
anatomical reasons only a low percentage of patients can be treated
surgically. For the remainder, several non-surgical treatment approaches
have been developed. In addition to percutaneous ethanol injection,
transarterial interventions, and several medical interventions,
radiofrequency thermal ablation has been investigated in coagulating HCC
lesions. OBJECTIVES: To evaluate the effects of radiofrequency thermal
ablation in HCC patients with respect to clinically relevant outcomes
(mortality, rate of recurrences, adverse events, quality of life, and
duration of hospital stay). SEARCH STRATEGY: We searched The Cochrane
Hepato-Biliary Group Trials Register, The Cochrane Controlled Trials
Register on The Cochrane Library, MEDLINE, Current Contents, EMBASE, and
Reference lists of the identified articles were checked for further
trials. SELECTION CRITERIA: All randomised or quasi-randomised clinical
trials investigating radiofrequency thermal ablation versus placebo, no
intervention, or any other therapeutic approach were considered for
inclusion, regardless of blinding, language, and publication status.
DATA COLLECTION AND ANALYSIS: Trial inclusion, quality assessment, and
data extraction were performed independently by two reviewers. Principal
investigators were contacted for further information. MAIN RESULTS: One
randomised trial which is still ongoing and only published as an interim
analysis was identified. This trial compared radiofrequency thermal
ablation versus percutaneous ethanol injection in 102 patients with
small HCC. With respect to mortality the trial showed no significant
difference between the two treatments (relative risk = 0.19, 95%
confidence interval 0.02 to 1.59). Concerning the recurrence free
survival the trial demonstrated no significant superiority of
radiofrequency thermal ablation versus percutaneous ethanol injection
(relative risk = 0.70, 95% confidence interval 0.46 -1.04). REVIEWER'S
CONCLUSIONS: At present, radiofrequency thermal ablation is an
insufficiently studied intervention for HCC.

Transcatheter arterial chemoembolization for hepatocellular carcinomas
in patients with celiac axis occlusion.
SO - J Vasc Interv Radiol 2002 Jul;13(7):689-94
AD - Department of Radiology, Seoul National University College of Medicine,
Seoul, Korea.
PURPOSE: To verify the hypothesis that most instances of celiac axis
occlusion in patients with hepatocellular carcinoma (HCC) are caused by
diaphragmatic compression and, therefore, transcatheter arterial
chemoembolization (TACE) can be performed through the compressed lumen
of the celiac axis. MATERIALS AND METHODS: The authors attempted to
perform TACE in 36 consecutive patients with HCC and celiac axis
occlusion. Spiral computed tomographic (CT) images were available in 26
patients. Initially, catheterization of the hepatic arteries was
attempted through the occluded celiac axis. If it failed,
catheterization was performed through the pancreaticoduodenal arcades.
The causes of celiac axis occlusion were evaluated based on spiral CT
and angiographic findings, access routes, technical success rates, and
related complications in superselective catheterization of hepatic
arteries. RESULTS: Among the 26 patients who underwent spiral CT,
diaphragmatic compression of the celiac axis was demonstrated in 23.
Selective catheterization of hepatic arteries was possible through the
occluded celiac axis in 23 patients (64%). In nine (25%) of the
remaining 13 patients, TACE was performed through the dilated
pancreaticoduodenal arcades from the superior mesenteric artery. As a
procedure-related complication, celiac axis dissection occurred in one
patient (3%). CONCLUSION: Most patients with celiac axis occlusion had
arcuate ligament compression. In TACE, the celiac artery occlusion could
be traversed directly and this should be the initial approach.

Dose-response relationship in local radiotherapy for hepatocellular
carcinoma.
SO - Int J Radiat Oncol Biol Phys 2002 Sep 1;54(1):150-5
AD - Department of Radiation Oncology, Brain Korea 21 Project for Medical
Science, Seoul, South Korea.
PURPOSE: Dose escalation using three-dimensional conformal radiotherapy
(3D-CRT) is based on the hypothesis that increasing the dose can enhance
tumor control. This study aimed to determine whether a dose-response
relationship exists in local radiotherapy for primary hepatocellular
carcinoma (HCC). METHODS AND MATERIALS: One hundred fifty-eight patients
The exclusion criteria included the presence of an extrahepatic
metastasis, liver cirrhosis of Child class C, tumors occupying more than
two-thirds of the entire liver, and a performance status on the Eastern
Cooperative Oncology Group scale of more than 3. Radiotherapy was given
to the field, including the tumor, with generous margin using 6- or
10-MV X-rays. The mean radiation dose was 48.2 +/- 7.9 Gy in daily
1.8-Gy fractions. The tumor response was assessed based on diagnostic
radiologic examinations, including a computed tomography scan, magnetic
resonance imaging, and hepatic artery angiography 4-8 weeks after the
completion of treatment. Liver toxicity and gastrointestinal
complications were evaluated. RESULTS: An objective response was
observed in 106 of 158 (67.1%) patients. Statistical analysis revealed
that the total dose was the most significant factor associated with the
tumor response. The response rates in patients treated with doses <40
Gy, 40-50 Gy, and >50 Gy were 29.2%, 68.6%, and 77.1%, respectively.
Survivals at 1 and 2 years after radiotherapy were 41.8% and 19.9%,
respectively, with a median survival time of 10 months. The rate of
liver toxicity according to the doses <40 Gy, 40-50 Gy, and >50 Gy was
4.2%, 5.9%, and 8.4%, respectively, and the rate of gastrointestinal
complications was 4.2%, 9.9%, and 13.2%, respectively. CONCLUSIONS: The
present study showed the existence of a dose-response relationship in
local radiotherapy for primary HCC. Only the radiation dose was a
significant factor for predicting an objective response. The results of
this study showed that 3D-CRT can theoretically be used for treating
primary HCC.

PURPOSE: To analyze the correlation of radiation-induced liver disease
(RILD) with patient-related and treatment-related dose-volume factors
and to describe the probability of RILD by a normal tissue complication
probability (NTCP) model for patients with hepatocellular carcinoma
(HCC) treated with three-dimensional conformal radiotherapy (3D-CRT).
patients with intrahepatic malignancies were treated with 3D-CRT at our
institution. Sixty-eight patients who were diagnosed with HCC and had
complete 3D dose-volume data were included in this study. Of the 68
patients, 50 had chronic viral hepatitis before treatment, either type B
or type C. According to the Child-Pugh classification for liver
cirrhosis, 53 patients were in class A and 15 in class B. Fifty-two
patients underwent transcatheter arterial chemoembolization with an
interval of at least 1 month between transcatheter arterial
chemoembolization and 3D-CRT to allow adequate recovery of hepatic
function. The mean dose of radiation to the isocenter was 50.2 +/- 5.9
Gy, in daily fractions of 1.8-2Gy. No patient received whole liver
irradiation. RILD was defined as Grade 3 or 4 hepatic toxicity according
to the Common Toxicity Criteria of the National Cancer Institute. All
patients were evaluated for RILD within 4 months of RT completion.
Three-dimensional treatment planning with dose-volume histogram analysis
of the normal liver was used to compare the dosimetric difference
between patients with and without RILD. Maximal likelihood analysis was
conducted to obtain the best estimates of parameters of the Lyman NTCP
model. Confidence intervals of the fitted parameters were estimated by
the profile likelihood method. RESULTS: Twelve of the 68 patients
developed RILD after 3D-CRT. None of the patient-related variables were
significantly associated with RILD. No difference was found in tumor
volume (780 cm(3) vs. 737 cm(3), p = 0.86), normal liver volume (1210
cm(3) vs. 1153 cm(3), p = 0.64), percentage of normal liver volume with
radiation dose >30 Gy (V(30 Gy); 42% vs. 33%, p = 0.05), and percentage
of normal liver volume with >50% of the isocenter dose (V(50%); 45% vs.
36%, p = 0.06) between patients with and without RILD. The mean hepatic
dose was significantly higher in patients with RILD (2504 cGy vs. 1965
cGy, p = 0.02). The probability of RILD in patients could be expressed
as follows: probability = 1/[1 + exp(-(0.12 x mean dose - 4.29))], with
coefficients significantly different from 0. The best estimates of the
parameters in the Lyman NTCP model were the volume effect parameter of
0.40, curve steepness parameter of 0.26, and 50% tolerance dose for
uniform irradiation of whole liver [TD(50)(1)] of 43 Gy. Patients with
RILD had a significantly higher NTCP than did those with no RILD (26.2%
vs. 15.8%; p = 0.006), using the best-estimated parameters. CONCLUSION:
Dose-volume histogram analysis can be effectively used to quantify the
tolerance of the liver to RT. Patients with RILD had received a
significantly higher mean dose to the liver and a significantly higher
NTCP. The fitted volume effect parameter of the Lyman NTCP model was
close to that from the literature, but much lower in our patients with
HCC and prevalent chronic viral hepatitis than that reported in other
series with patients with normal liver function. Additional efforts
should be made to test other models to describe the radiation tolerance
of the liver for Asian patients with HCC and preexisting compromised
hepatic reserve.
