Gastric cancer is one of the most common cancers in the world. The
prognosis of the disease is poor, with only 40% of patients eligible to
undergo potentially curative surgery. Even for those patients who
undergo a complete resection, the rate of recurrence is very high.
Extensive studies of multidisciplinary adjuvant treatment have been
conducted seeking to improve the cure rates in the past two decades. The
benefit of D2 dissection is still controversial and is undergoing
prospective evaluation. Preliminary results from the United States
Gastrointestinal Intergroup study, a well designed trial, have shown
overall survival benefit of postoperative chemoradiation therapy.
Neoadjuvant chemotherapy or chemoradiation is under active study in
order to increase the number of patients to undergo potential curative
surgery. Although many chemotherapy regimens have been developed
recently, only modest clinical efficacy has been demonstrated for
advanced metastatic disease. So far, there is no single regimen
considered to be standard.

Growth inhibition of gastric cancer cells by all-trans retinoic acid
through arresting cell cycle progression.
SO - Chin Med J (Engl) 2001 Sep;114(9):958-61
AD - Key Laboratory of Ministry of Education for Cell Biology and Tumor Cell
Engineering, School of Life Sciences, Xiamen University, Xiamen 361005,
China. xgwu@xmu.edu.cn
OBJECTIVE: To investigate the mechanism of all-trans retinoic acid
(ATRA) on the regulation of the cell cycle in gastric cancer cells.
METHODS: The protein level was detected by Western blot.
Immunoprecipitation was used in protein kinase activity determination.
Cell growth and cell cycle phase were examined by MTT assay and
flow-cytometric analysis, respectively. RESULTS: ATRA could effectively
induce G0/G1 arrest and inhibit cell growth in certain human gastric
cancer cell lines. ATRA might induce p21WAF1/CIP1 expression in
ATRA-sensitive cell lines through p53-dependent and p53-independent
pathways. Induction of p21WAF1/CIP1 caused decrease in CDK4 and CDK2
activities independent of CDK4 and CDK2 protein expression levels. In
addition, the dephosphorylated form of Rb protein increased because of
the down-regulation of CDK4 and CDK2 activities by ATRA. CONCLUSIONS:
Growth inhibition on gastric cancer cells by ATRA occurs through the
regulation of relevant proteins leading to the arrest of cell cycle
progression.

[Preliminary clinical comparison of HLF and ELF regimen in the treatment
of advanced gastric carcinoma in middle-aged and elderly patients]
SO - Zhonghua Zhong Liu Za Zhi 2000 Sep;22(5):411-3
AD - Department of Gastrointestinal Medicine, Sun Yat-sen Memorial Hospital,
Sun Yat-sen Medical University, Guangzhou 510120, China.
OBJECTIVE: To observe the therapeutic effects and toxicity of HLF
(hydroxycamptothecin HCPT/leucovorin LV/fluorouracil 5-Fu) regimen and
ELF (etoposide VP-16/LV/5-Fu) regimen in middle-aged and elderly
patients with advanced gastric carcinoma. METHODS: A group of
twenty-five cases were treated with HLF regimen, and the other group of
23 cases were treated with ELF regimen. RESULTS: Of the 25 cases treated
with HLF regimen, there was no complete remission (CR), but there were
12 partial response (PR), 11 no response (NC), and 2 had progressive
disease (PD). The response rate (RR) was 48.0%. Of the 23 patients
treated with ELF regimen, there was no CR, there were 9 PR, 11 NC, and 3
PD. The RR was 39.1% (P > 0.05). The main toxicity was myelosuppression
and stomatocace. Grade III-IV stomatocace in HLF regimen group (68.0%)
was more commonly seen than that in ELF regimen group (39.1%, P < 0.05).
There was no cardiac or renal toxicity observed. CONCLUSION: HLF regimen
is promising for treatment of advanced gastric carcinoma in middle-aged
and elderly patients with the merits of low toxicity affecting heart,
kidney and bladder except stomatocace, which is worthy of further
clinical trial.

[Adjuvant chemotherapy after curative resection for gastric
cancer-5'-DFUR + cisplatin vs 5'-DFUR]
SO - Gan To Kagaku Ryoho 2002 Jan;29(1):61-5
AD - Dept. of Surgery, Osaka National Hospital.
A prospective randomized study involving gastric cancer patients was
conducted to evaluate combined adjuvant chemotherapy. Forty-two patients
under 80 years of age who underwent a curative resection of pathologic
stage II or III gastric cancer were randomly assigned to receive
adjuvant chemotherapy containing the following two regimens from 1993 to
1996. A) Oral 5'-deoxy-5-fluorouridin (5'-DFUR) plus cisplatin: 5'-DFUR,
daily administration, combined with CDDP 15 mg/m2/day, 30-min drip
infusion, fortnightly for 8 weeks, repeated every 16 weeks. B) Oral
5'-DFUR alone: 5'-DFUR, daily administration. The dosages of 5'-DFUR
were assigned according to the patients' body surface area (BSA): BSA <
1.7 m2, 600 mg and BSA > or = 1.7 m2, 800 mg, daily administration, bid.
Twenty patients were assigned to regimen A, and 22 to regimen B. All
clinicopathological factors were equally distributed in each regimen. No
adverse reactions greater than grade 3 occurred in either regimen. There
was no significant difference between the two regimens in overall
survival or overall disease-free survival. For patients with positive
nodes, the 5-year disease-free survival rates were 56.4% in A and 38.3%
in B (p = 0.29). In stage III patients, the 5-year disease-free survival
rates were 55.6% in A and 20.7% in B (p = 0.26). No significant survival
benefit was observed with the combined chemotherapeutic regimen, 5'-DFUR
plus cisplatin, compared with 5'-DFUR alone.

Relevant prognostic factors in gastric cancer: ten-year results of the
German Gastric Cancer Study.
SO - Ann Surg 1998 Oct;228(4):449-61
AD - Chirurgische Klinik und Poliklinik, Klinikum rechts der Isar, Technische
Universitat Munchen, Germany.
OBJECTIVE: In 1986 a prospective multicenter observation trial in
patients with resected gastric cancer was initiated in Germany. An
analysis of prognostic factors based on the 10-year survival data is now
presented. PATIENTS AND METHODS: A total of 1654 patients treated for
gastric cancer between 1986 and 1989 at 19 centers in Germany and
Austria were included. The resected specimen were evaluated
histopathologically according to a standardized protocol. The extent of
lymphadenectomy was classified after surgery based on the number of
removed lymph nodes on histopathologic assessment (25 or fewer removed
nodes, D1 or standard lymphadenectomy; >25 removed nodes, D2 or extended
lymphadenectomy). Endpoint of the study was death. Follow-up is complete
for 97% of the included patients (median follow-up of the surviving
patients is 8.4 years). Prognostic factors were assessed by multivariate
analysis. RESULTS: A complete macroscopic and microscopic tumor
resection (R0 resection according to the UICC 1997) could be achieved in
1182 of the 1654 patients (71.5%). The calculated 10-year survival rate
in the entire patient population was 26.3% +/- 4.7%; it was 36.1% +/-
1.6% after an R0 resection. In the total patient population there was an
independent prognostic effect of the ratio between invaded and removed
lymph nodes, the residual tumor (R) category, the pT category, the
presence of postsurgical complications, and the presence of distant
metastases. Multivariate analysis in the subgroup of patients who had a
UICC R0 resection confirmed the nodal status, the pT category, and the
presence of postsurgical complications as the major independent
prognostic factors. The extent of lymph node dissection had a
significant and independent effect on the 10-year survival rate in
patients with stage II tumors. This effect was present in the subgroups
with (pT2N1) and without (pT3N0) lymph node metastases on standard
histopathologic assessment. The beneficial effect of extended lymph node
dissection for stage II tumors persisted when patients with insufficient
lymph node dissection (<15 nodes) were excluded from the analysis. There
was no difference in the postsurgical morbidity and mortality rates
between patients with standard and extended lymph node dissection.
CONCLUSIONS: Lymph node ratio and lymph node status are the most
important prognostic factors in patients with resected gastric cancer.
In experienced centers, extended lymph node dissection does not increase
the mortality or morbidity rate of resection for gastric cancer but
markedly improves long-term survival in patients with stage II tumors.
This effect appears to be independent of the phenomenon of stage
migration.

Evaluation of the cost for laparoscopic-assisted Billroth I gastrectomy.
SO - Surg Endosc 2001 Sep;15(9):932-6
AD - Department of Surgery I, Oita Medical University, 1-1 Idaigaoka,
Hasama-machi, Oita 879-5593, Japan.
BACKGROUND: Despite the rapid spread of laparoscopic gastric surgery in
Japan, no one has yet evaluated the costs for this new technique. The
aim of this study was to analyze and compare the hospital charges for
laparoscopic-assisted gastrectomy with those for conventional open
gastrectomy. METHODS: The study included 48 consecutive patients who
underwent laparoscopic-assisted Billroth I gastrectomy and 43 who had a
conventional open Billroth I gastrectomy for cure of early gastric
costs incurred during the hospital stay; they were divided into charges
for consultation, prescription, injection, nursing care, operating
theater, laboratory, radiology, ward and meal, and others. RESULTS: The
patients who underwent laparoscopic gastrectomy were similar to those
who had open gastrectomy in terms of symptoms, concurrent illness,
operation time, proximal resection margin, number of harvested lymph
nodes, and stage of the disease. Hospital stay after laparoscopic
gastrectomy was shorter than that after open gastrectomy (16.1 vs 20.5
days, p < 0.01). Charges for nursing care, charges for ward and meal,
and total hospital charges were less in the laparoscopic group than in
the open group ( yen5800 vs yen8010, p < 0.01; yen461 x 10(3) vs yen512
x 10(3), p < 0.05; yen1336 x 10(3) vs yen1411 x 10(3), p = 0.072). When
we compared laparoscopic gastrectomies performed during 1994-96 with
those done during 1997-2000, we found a decrease in charges for ward and
meal and total hospital charges ( yen498 x 10(3) vs yen421 x 10(3), p <
0.01; yen1390 x 10(3) vs yen1277 x 103, p < 0.01). Conclusion:
Laparoscopic-assisted Billroth I gastrectomy is less expensive than
conventional open Billroth I gastrectomy because both the postoperative
recovery period and the hospital stay are shorter. In patients who
undergo gastrectomy, the additional costs of the disposable instruments
can be fully offset by the lower charges for ward and meal and nursing
care associated with laparoscopic gastrectomy.

Total gastrectomy with distal pancreatectomy and splenectomy for
advanced gastric cancer.
SO - J Surg Res 2001 Dec;101(2):196-201
AD - Department of Surgery, Tone Chuo Hospital, Numata-City, Gunma, Japan.
BACKGROUND: Pancreaticosplenectomy (PS) is often performed
simultaneously with total gastrectomy (TG) to facilitate dissection of
the lymph nodes around the splenic artery and splenic hilus. To evaluate
the effects of PS on survival, a retrospective study was performed.
METHODS: Various clinicopathological factors influencing lymph node
metastasis around the splenic hilus (No. 10) and the splenic artery (No.
11) were studied retrospectively in the upper or middle third of
advanced gastric cancer patients who underwent TG with PS. The
postoperative morbidity, mortality, and survival rate of patients who
underwent TG with PS (the TG with PS group) were compared with those of
patients who underwent TG alone (the TG-alone group). RESULTS: Tumor
size larger than 41 mm and lymph node No. 2 metastasis were
independently correlated with lymph node No. 10 and No. 11 metastasis.
The mortality rate was similar, but the morbidity rate was significantly
higher in the TG with PS group. In the patients with stage I and III,
there was no significant difference between the two groups, but in the
patients with stage II, the TG-alone group was significantly better than
the TG with PS group (P = 0.0400). CONCLUSIONS: Combined PS with TG
should never be performed as the standard surgical procedure for every
stage of gastric cancer, especially stage II.

[Relationship between extent of tumor resection and prognosis: an
evaluation in 533 cases of gastric cancer]
SO - Zhonghua Zhong Liu Za Zhi 1999 Nov;21(6):467-9
AD - Department of Oncology, First Affiliated Hospital, China Medical
University, Shenyang, 110001.
OBJECTIVE: To evaluate prognosis of patients with stomach cancer based
on the extent of tumor resection. METHODS: Five hundred and thirty-three
cases of gastric cancer resected from 1980 through 1990 were divided
into 3 categories A, B, and C, in the order of decreasing completeness
of tumor resection as set forth in the 12th edition of "Rules for
Gastric Cancer in Japan". RESULTS: There were 157 cases in category A,
209 cases in category B and 167 cases in category C. Their survival rate
was 80.9%, 34.9%, and 9%, respectively. In category A and B, the depth
of tumor invasion and lymph node metastasis were the major factors
affecting survival rate. In the presence of lymph node metastasis,
prognosis was dependent on which station (D1-D3) of lymph nodes
dissected. In category B, if dissection covered D3 but metastasis was
limited to I or II, the 5-year survival rate was 48%; if lymph node
dissection performed was limited to the same station of lymph nodes
where metastasis occurred, the 5-year survival rate dropped to 22.4% (P
< 0.05). In case cancer left over at the cutting edge, the completeness
of resection might drop from category A or B to C, and the 5-year
survival rate correspondingly decreased to 6% and 12.2%, respectively.
CONCLUSION: In order to ensure completeness of tumor resection, lymph
node station dissected should be farther than that with metastasis, and
the distance between the tumor and the cutting edge should be long
enough to prevent residual tumor left behind.

Tumor load and surgical palliation in gastric cancer.
SO - Hepatogastroenterology 2001 Sep-Oct;48(41):1219-21
AD - University Medical Center, St Radboud Nijmegen, The Netherlands.
BACKGROUND/AIMS: Most patients with gastric cancer will have resection,
even if their disease stage is beyond curability. Proper criteria to
assess tumor load in patients deemed noncurative are lacking, and
therefore, it is not clear which of these patients will benefit from
resection. METHODOLOGY: Of 996 gastric cancer patients who had
laparotomy in a national randomized trial of lymphadenectomy for gastric
cancer, 285 (29%) were found to be noncurable because of remnant tumor,
peritoneal metastases, distant lymph node metastases or liver
metastases. They underwent a palliative procedure considered appropriate
by the surgeon. Tumor load in this group was analyzed retrospectively by
calculating the number of noncurability signs. RESULTS: The number of
signs of noncurability was related to the type of surgical palliation
chosen by the surgeon: of those patients with only one sign of
noncurability, 68% had a palliative stomach resection but, of patients
with two or more positive signs of noncurability only 36% had a stomach
resection. Median survival after palliative resection was 253 days
compared to 169 days after a nonresective procedure (P = 0.002). This
survival advantage for resected patients disappeared when two or more
signs of noncurability were found. CONCLUSIONS: For patients deemed
noncurative, survival depends on tumor load. Accurate preoperative
assessment of tumor spread may prevent unnecessary high-risk surgical
interventions for patients with noncurative gastric cancer.

1114 total gastrectomies in the surgical treatment of primary gastric
adenocarcinoma--a 30-year single institution experience.

BACKGROUND/AIMS: Surgical therapy still represents the standard
treatment for gastric carcinoma. Due to epidemiology and tumor stage,
total gastrectomy is the most often required extent of gastric resection
to obtain a potentially curative status. After a 30-year period we
overviewed 1114 total gastrectomies, to our knowledge one of the biggest
single-institution series in the Western Hemisphere. METHODOLOGY: Among
1998, 1114 patients underwent total gastrectomy. This prospectively
documented series was retrospectively analyzed with special focus on
various time periods. RESULTS: A constant increase of proximal gastric
carcinomas was noted. R0-resections were feasible in 84.6% of total
gastrectomies. Morbidity and mortality decreased to 22.2% and 5.5%,
respectively, in the last decade. Overall 5-years survival rate was
32.4%. Survival was strongly influenced by tumor stage and
R-classification. Overall and prognosis after R0-resection showed a
significant time-dependent improvement. CONCLUSIONS: Total gastrectomy
requires intensive surgical skills and can be performed with acceptable
morbidity and low mortality. Survival after total gastrectomy can be
improved with increasing experience, and the aim of total gastrectomy
for gastric carcinoma should always focus on a R0-resection.

AD - Department of Surgery, Inje University Paik Hospital, 85 2-Ka, Jur-Dong,
Chung-Ku, Seoul, 100-032, Korea. jinpokkim@chollian.net
BACKGROUND/AIMS: Although the therapeutic results of gastric cancer have
markedly improved, it still remains the most common cancer death in
Korea. METHODOLOGY: The clinicopathologic characteristics were analyzed
for 11,491 consecutive patients who underwent operation for gastric
cancer at the Department of Surgery, Seoul National University Hospital
from 1971 to 1997. We also evaluated the survival and prognostic factors
for 9,262 consecutive patients from 1981 to 1996. The prognostic
significance of treatment modality [surgery alone, surgery +
chemotherapy, surgery + immunotherapy + chemotherapy
(immunochemo-surgery)] were evaluated in stage III gastric cancer.
RESULTS: The 5-year survival rate of overall patients was 55.8%, and
that of patients who received curative resection was 64.8%. The 5-year
survival rates according to TNM stage were 92.9% for Ia, 84.2% for Ib,
69.3% for II, 45.8% for IIIa, 29.6% for IIIb and 9.2% for IV. Depending
on the extent of resection, the 5-year survival rates were 68.7% for
STG, 45.4% for TG, 19.6% for combined resection and there was no 5-year
survivor in the nonresection group. Regarding adjuvant treatment
modality, significant survival difference was observed in stage III
patients. The 5-year survival rates were 44.8% for the
immunochemo-surgery group, 36.8% for the surgery + chemotherapy group
and 27.2% for the surgery alone group. CONCLUSIONS: Curative resection,
depth of invasion and lymph node metastasis were the most significant
prognostic factors in gastric cancer. Consequently, early detection and
curative resection with radical lymph node dissection, followed by
immunochemotherapy especially in patients with stage III gastric cancer
should be recommended as a standard treatment principle for patients
with gastric cancer.

Classification, diagnosis and surgical treatment of carcinomas of the
gastroesophageal junction.
SO - Hepatogastroenterology 2001 Sep-Oct;48(41):1231-7
AD - Department of Visceral and Vascular Surgery, University of Cologne,
Joseph-Stelzmann Str. 9, 50924 Cologne, Germany.
The incidence of adenocarcinoma of the gastroesophageal junction has
risen faster than that of any other malignancy in various western
countries. Adenocarcinoma of the gastroesophageal junction can be
topographically classified into three types: carcinomas of the distal
esophagus (type I), true carcinomas of the cardia (type II) and
carcinomas of the subcardial region (type III). This surgical
classification has proven to be of value for planning the extent of
resection and for comparing epidemiologic data and therapeutic results
of different series. The preoperative assignment is achieved by contrast
X-ray and endoscopy and enables the surgeon to plan preoperatively the
adequate extent of the resection. The type I-adenocarcinoma represents a
distal esophageal cancer and consequently is treated by esophageal
resection as transhiatal subtotal radical esophagectomy or in case of
more proximal carcinoma by transthoracic en bloc esophagectomy. The type
II- and type III-adenocarcinomas are treated by a gastrectomy and distal
esophageal resection with D2-lymphadenectomy via an abdominal and
transhiatal approach. In case of an advanced carcinoma with high risk of
incomplete resection, neoadjuvant radiochemotherapy should be taken into
consideration.

Palliation with a glimmer of hope: management of resectable gastric
cancer with peritoneal carcinomatosis.
SO - Hepatogastroenterology 2001 Sep-Oct;48(41):1238-47
AD - Washington Cancer Institute, Washington, DC 20010, USA.
In the United States peritoneal seeding from primary gastric cancer
occurs in 20-30% of patients. The diagnosis of this advanced disease is
usually not provided by clinical studies prior to abdominal exploration.
The surgeon is forced to make an intraoperative judgement concerning the
risks and benefits of an aggressive management plan versus supportive
care. A treatment strategy for this difficult group of patients has been
devised and tested in phase II studies. It utilizes extended gastrectomy
plus peritonectomy to maximally cytoreduce tumor combined with
perioperative intraperitoneal chemotherapy. The perioperative
intraperitoneal mitomycin-C chemotherapy is heated to 42 degrees C and
manually distributed to provide uniform treatment to all peritoneal
surfaces and the resection site. Early postoperative intraperitoneal
5-fluorouracil is gravity distributed. The pharmacologic parameters have
been established. Relevant clinical information was collected in this
review. Five-year survival of these patients in whom a complete
cytoreduction was possible has been observed and a prolonged median
survival occurs. Gastrectomy with peritonectomy to eliminate all visible
implants combined with perioperative intraperitoneal chemotherapy should
be considered in all patients with primary gastric cancer and peritoneal
carcinomatosis.

Is submucosal epinephrine injection necessary before polypectomy? A
prospective, comparative study.
SO - Hepatogastroenterology 2001 Sep-Oct;48(41):1379-82
AD - Buddhish Tzu Chi Dalin General Hospital, Taiwan, ROC.
BACKGROUND/AIMS: Polyps of the gastrointestinal tract are usually
removed due to their link to bleeding, obstruction and malignancy.
However, complications may occur following polypectomy. The aim of this
study was to assess whether submucosal epinephrine injection before
polypectomy could reduce the incidence of bleeding and perforation.
polyps of the gastrointestinal tract found in our endoscopic unit were
randomized to receive submucosal epinephrine injection (epinephrine
group) or no injection (control group) before polypectomy. In the
epinephrine group, epinephrine (1:10,000) was injected surrounding the
stalk of the polyp until the mucosa was blanched and bulged. The
patients were observed for complications in the following month.
RESULTS: A total of 120 patients with 151 sessile polyps were enrolled
in this study. In the epinephrine group, 75 polyps (n = 68) were
randomized to receive epinephrine injection before polypectomy. In the
control group, 76 polyps (n = 61) underwent polypectomy without
epinephrine injection. In both groups, there was no significant
difference in clinical features including the sizes of the polyps and
their stalks, the location of polyps and the pathological diagnosis.
There were a total of nine episodes of post-polypectomy hemorrhage, two
in the epinephrine group and seven in the control group (2/75 vs. 7/76)
(P = 0.07). One case in the epinephrine group experienced delayed
bleeding (4 days later). Immediate hemorrhage occurred less in the
epinephrine group than that in the control group (1/75 vs. 7/76, P =
0.03). There was one case of perforation in each group. CONCLUSIONS:
Epinephrine injection prior to polypectomy is effective in preventing
immediate bleeding.

Factors influencing the development of small intestinal obstruction
following total gastrectomy for gastric cancer: the impact of
reconstructive route in the Roux-en-Y procedure.

AD - Department of General Surgery, Fukuoka Dental College Hospital, Tamura
2-15-1, Sawara-ku, Fukuoka 814-0193, Japan.
BACKGROUND/AIMS: The factors influencing the development of small
intestinal obstruction following gastric surgery are controversial.
METHODOLOGY: Univariate and multivariate analyses were carried out on
data from 48 patients with gastric cancer who underwent total
gastrectomy and Roux-en-Y reconstruction for a potential cure. RESULTS:
Of these 48 patients, 11 (22.9%) presented with mechanical obstruction
in the small intestine postoperatively. There were no statistically
significant differences with regard to age, sex, and the presenting
pathology. The development of obstruction was not related to a longer
operation time, a greater estimated blood loss during surgery, an
extensive lymph node dissection and a combined resection of adjacent
organs. The probability that the antecolic anastomosis would cause
obstruction was significant when compared with findings in case of the
retrocolic anastomosis (P < 0.05). In the multivariate logistic
regression analysis, the significant risk factors related to the
development of small intestinal obstruction proved to be reconstructive
route of jejunal loop. CONCLUSIONS: In potentially curative patients
undergoing total gastrectomy, retrocolic anastomosis should be attempted
to prevent the development of postoperative intestinal obstruction.

BACKGROUND/AIMS: The relationship between prognostic factors and
survival time after noncurative gastric resection in patients with
advanced gastric cancer was examined by a retrospective review of data
on 364 patients. METHODOLOGY: There were 168 patients without metastasis
to the liver or peritoneum (group A), 127 with peritoneal metastasis and
no liver metastasis (group B), 50 with liver metastasis and no
peritoneal metastasis (group C) and 19 with synchronous liver and
peritoneal metastases (group D). Patients were primarily treated with
the following 3 drugs: the fluorinated pyrimidines, cisplatin, and
mitomycin C. RESULTS: Patients in group D had a very poor prognosis as
compared with the other groups. Multivariate analysis using the Cox's
proportional hazard model adjusted for sex, age, and other covariants
indicated that lymph node metastasis, lymph node dissection, and
fluorinated pyrimidines for group A, cisplatin for group B, and lymph
node dissection for group C were independent prognostic factors. An
analysis of patients excluding cases who died within 30 days after
surgery revealed that lymph node dissection for group A, lymph node
dissection and cisplatin for group B, and lymph node dissection for
group C were independent prognostic factors. CONCLUSIONS: Treatment
protocol specific for the residual disease may improve the survival of
patients with advanced gastric cancer treated by noncurative resection.

BACKGROUND/AIMS: The prognosis of patients with scirrhous gastric
carcinoma has been poorest. METHODOLOGY: To clarify the role of surgical
treatment, 233 patients with a primary scirrhous gastric carcinoma were
retrospectively analyzed. RESULTS: Of the 233 patients, 182 underwent
surgical resection, while the other 51 did not. The median survival time
of those with unresectable tumors was 88.0 +/- 15.3 days and that of
those who underwent resection was 380.0 +/- 41.8 days. In the 182
patients who underwent resection, multivariate analysis revealed four
significant factors; lymphatic invasion, serosal invasion, curability,
and lymph node dissection. Of these, curability was the most
significant. The median survival time of patients whose tumor were
curatively resected was 727.0 +/- 116.3 days, significantly longer than
272 +/- 34.9 days for those whose resection ended noncuratively. In 65
patients whose tumor was curatively resected, subset analyses of factors
by multivariate analyses revealed an absence of serosal invasion as the
single significant prognosticator. The 5-year survival rate was 55.6% in
patients with scirrhous cancer without serosal invasion. CONCLUSIONS:
For patients with scirrhous gastric carcinoma, palliative resection
should not be attempted for poor outcome. However, if curative resection
seems feasible, radical surgery would be justified, especially for
tumors without serosal exposure.

BACKGROUND/AIMS: Total gastrectomy has generally been performed for the
treatment of early gastric cancers involving the upper third of the
stomach. However, proximal gastrectomy has also been used for the
treatment of cardial early gastric cancer. METHODOLOGY: To compare the
nutritional parameters after proximal gastrectomy with the parameters
after total gastrectomy, and to also determine the advantages of the
postoperative nutritional states, a retrospective analysis was made to
evaluate the nutritional status of patients with early gastric cancer
who underwent proximal gastrectomy with those undergoing total
gastrectomy. Forty-nine patients were studied for one year after
surgery; 9 underwent proximal gastrectomy while 40 had a total
gastrectomy. RESULTS: Proximal gastrectomy allowed the patient to better
maintain both their nutritional parameters and body weight. CONCLUSIONS:
Proximal gastrectomy was thus found to be a beneficial modality for
early gastric cancer patients regarding terms of the postoperative
nutritional status, in comparison to total gastrectomy.

Postoperative morbidity and mortality after gastrectomy for gastric
carcinoma.

BACKGROUND/AIMS: Surgical technique and postoperative care for gastric
cancer have significantly improved in recent years. However, whether
postoperative morbidity or mortality rates after gastrectomy for gastric
cancer were reduced or not in recent years was unclear. In this study,
we analyzed the chronological changes of postoperative morbidity and
mortality rates, and we analyzed risk factors for postoperative
morbidity and mortality in patients undergoing gastrectomy for
carcinomas of the stomach. METHODOLOGY: A total of 887 patients with
basis of chronology. The first group included patients treated over the
period 1985 to 1988 (n = 324); the second group, 1989 to 1992 (n = 300);
and the third group, 1993 to 1996 (n = 263). Postoperative morbidity
rates and mortality rates were compared among the three groups. Also,
significant risk factors affecting postoperative morbidity and
in-hospital mortality were analyzed by the multiple logistic regression
analysis. RESULTS: Postoperative complications were detected in 95
patients (10.7%) and in-hospital mortality rate was 2.4% (21/887).
Postoperative morbidity rates were 10.5%, 11%, and 10.6% in the first,
second, and third groups, respectively and postoperative mortality rates
were 2.5%, 2%, and 2.7%, respectively. These postoperative morbidity and
mortality rates were not different between the groups (P = 0.979 and P =
0.866). The most common postoperative complication was anastomotic
leakage (56/95, 58.9%). Significant risk factors affecting in-hospital
mortality were Stage IV (P = 0.006) and noncurative gastric resection (P
= 0.004). However, the extent of lymph node dissection, combined
resection, or the existence of preoperative complications were not
significant risk factors of in-hospital mortality by multiple logistic
regression analysis. CONCLUSIONS: These results indicate that patients
with far-advanced gastric cancer might have a high risk of postoperative
mortality. In noncurative operations for patients with advanced gastric
cancer, unnecessary lymph node dissection or combined resection should
be avoided.

BACKGROUND: Gastric juice vitamin C may be protective against gastric
carcinogenesis but concentrations are significantly reduced by
Helicobacter pylori infection. We investigated the in vitro effects of
vitamin C at concentrations comparable with those found in gastric juice
on gastric cancer cells and H pylori. METHODS: Gastric cancer cell lines
and various H pylori strains were treated with L-ascorbic acid for up to
72 hours. Cell viability, and protein and DNA synthesis were determined.
Flow cytometry was used for assessment of H pylori adherence, cell cycle
distribution, and apoptosis. H pylori growth and its haemagglutination
activity were determined using viability count and microtitration assay.
RESULTS: Vitamin C induced a significant dose dependent growth
inhibition of gastric AGS and MKN45 cells but this effect was
significantly reduced at levels similar to those in gastric juice of H
pylori infected patients (<50 microM). Although vitamin C had no obvious
effect on H pylori growth, haemagglutination activity, or adherence
ability to gastric AGS cells compared with untreated controls, it
significantly enhanced H pylori associated apoptosis and induced cell
cycle arrest in these cells. CONCLUSION: Vitamin C may inhibit gastric
cancer cell growth and alter H pylori induced cell cycle events at
concentrations comparable with those in gastric juice, but has no effect
on H pylori growth or pathogenicity. However, the inhibitory effect on
gastric cancer cells was lost at vitamin C concentrations found in
patients with H pylori infection.

Laser augmented by brachytherapy versus laser alone in the palliation of
adenocarcinoma of the oesophagus and cardia: a randomised study.
SO - Gut 2002 Feb;50(2):224-7
AD - National Medical Laser Centre, Institute of Surgical Studies, Royal Free
and University College Medical School, London, UK.
BACKGROUND: Many patients with advanced malignant dysphagia are not
suitable for definitive treatment. The best option for palliation of
dysphagia varies between patients. This paper looks at a simple
technique for enhancing laser recanalisation. AIM: To assess the value
of adjunctive brachytherapy in prolonging palliation of malignant
dysphagia by endoscopic laser therapy. PATIENTS: Twenty two patients
with advanced malignant dysphagia due to adenocarcinoma of the
oesophagus or gastric cardia, unsuitable for surgery or radical
chemoradiotherapy. METHODS: Patients able to eat a soft diet after laser
recanalisation were randomised to no further therapy or a single
treatment with brachytherapy (10 Gy). Results were judged on the quality
and duration of dysphagia palliation, need for subsequent intervention,
complications, and survival. RESULTS: The median dysphagia score for all
patients two weeks after initial treatment was 1 (some solids). The
median dysphagia palliated interval from the end of initial treatment to
recurrent dysphagia or death increased from five weeks (control group)
to 19 weeks (brachytherapy group). Three patients had some odynophagia
for up to six weeks after brachytherapy. There was no other treatment
related morbidity or mortality. Further intervention was required in 10
of 11 control patients (median five further procedures) compared with
7/11 brachytherapy patients (median two further procedures). There was
no difference in survival (median 20 weeks (control), 26 weeks
(brachytherapy)). CONCLUSIONS: Laser therapy followed by brachytherapy
is a safe, straightforward, and effective option for palliating advanced
malignant dysphagia, which is complementary to stent insertion.

A quantitative change of the enlargement of the biopsy specimen resulted
in a qualitative change for endoscopy from only diagnosis to include
therapy. This change of quality was also caused by another quantitative
change of the size of detectable lesion, which was made smaller.

The advent of EMR made a major change in the strategy for early gastric
cancer. Recently, many modified EMR techniques have been developed, such
as using an endoscopic cap, a special tube, and so forth. We regard
EMR-L as the first-line procedure because of its simplicity and ease,
and it is hoped that all endoscopists will learn this procedure to
improve the quality of life of patients who suffer from gastric cancer.

582 patients were gastrectomized between 1976 and 1996 in the Department
for Gastrointestinal Surgery in Katowice/Poland for gastric cancer.
Before 1985 esophago-jejunal anastomosis have been accomplished using a
simple end-to-end or special end-to-side (Schreiber-Eichfuss) method
with jejunoplication. Thereafter we used an end-to-end invagination
method with 4-5 cm deep intussusception of the first raw of sutures into
jejunum. Comparison of the occurrence of short and long term
complications at the site of esophago-jejunal anastomosis showed that
invagination technique is safer that the previous one. It is associated
with the lower rate of short and long term complications (dehiscence,
stenosis, oesophagitis). Details of the surgical procedure facilitating
the accomplishment of the tight and safe anastomosis are presented.

[Reconstruction methods for the continuous digestive tract using

undergoing surgery for stomach cancer. Personal evaluation]

AD - Kliniki Chirurgii Onkologicznej Akademii Medycznej w Lodzi.
From 1984 to 1994, 152 patients were operated for gastric cancer in
Clinical Department of Surgical Oncology, Medical University of Lodz.
Patients age ranged from 31 to 82 years (mean age-61.2). The purpose of
this study was to evaluate the methods of reconstruction of
gastrointestinal tract (GIT) continuity. Our material comprised patients
who underwent total gastrectomy for gastric cancer. In 52 patients
radical procedure--total gastrectomy--was performed, with reconstruction
of gastrointestinal tract continuity. The latter part of surgery was
accomplished using different methods: Roux-Y anastomosis-10 patients
(19.2%); esophago-jejunal "end to side" anastomosis-8 patients (15.4%);
Hunt-Lawrence-Rodino anastomosis-34(65%). During procedures staplers and
VALTRAC rings were used, as well as ultrasound selector and argon
coagulator for hepatic and pancreatic resections. Quality of life after
gastrectomy was determined on the basis of interviews taken from
patients, in whom GIT continuity was reconstructed with or without
intestinal pouch creation. We also evaluated incidence and type of
complications after such procedures. Perioperative mortality in our
material was 7.7%. We concluded that the best results was achieved when
continuity of gastrointestinal tract after total gastrectomy was
reconstructed with intestinal (first loop of jejunum) pouch creation
(Hunt-Lawrence procedure). This method warranted high quality of life
and low incidence of complications. Staplers enables us to shorten time
of procedure and to decrease the number of anastomosis leaks, so that
our results of surgical treatment of patients with gastric cancer were
better.

From I 1986 to I 1997 we have operated in our Department 333 patients
with gastric cancer. Resection has been done in 204 cases (with total
resection rate 97%). Mostly there were patients with advanced disease
(totally 160 cases with III and IV stage according to UICC
classification). Metastases to regional lymph nodes were confirmed at
186 patients (91%). In every resection for cure and in palliative
operations, where it was possible, we have done lymphangiectomy
contained D1 and D2 level of regional lymph nodes. We achieved 28.9%
5-year survival rate (according to Kaplan-Meier) with postoperative
mortality 2% and low number of surgical complications. Total resection
of the stomach with regional node dissection (levels D1 and D2) is good
and safe procedure and should be performed in majority cases of gastric
cancer particularly in early and middle stages of disease.

Stomach is the most common site of extranodal lymphoma, but lymphoma's
biology differs from other types of gastric cancer. From 1982 to 1994,
80 cases of primary gastric lymphoma were treated in Cancer Center in
Krakow. In order to assess the best mode of treatment the retrospective
analysis of disease related parameters was performed. Sixty four
patients were primary treated with surgery, and 11 with radiotherapy.
After surgery 21 patients received adjuvant chemo or radiotherapy.
