The role of aggressive surgical resections as well as criteria for
resectability in patients with advanced carcinoid tumors is not clearly
defined. Thirty patients (17 male and 13 female) who were previously
diagnosed to have "unresectable carcinoid disease" were treated using a
multimodality approach over a period of 2 years. Extensive liver
involvement was present in 28 of 30 (93%) of the cases. Small bowel
involvement was noted in 22 of 30 (73%), and
peritoneal/retroperitoneal/mesenteric invasion was observed in 15 of 30
(50%) of the cases. Three patients had remote metastases (brain, bone,
and eye). Twenty of 30 (66%) patients had carcinoid syndrome with
severely disabling symptoms. Eight patients (26%) had small bowel
obstruction. All patients underwent at least one surgical
exploration/intervention. Radiofrequency ablation (RFA) of one or more
liver lesions was performed as an adjunct in 22 of 30 (73%) patients.
Six patients (20%) had a second surgical procedure. There were 11
complications in eight patients (27%) after the initial operation.
Median hospital stay for patients who underwent RFA only, RFA/liver
resection, and liver resection with abdominal tumor debulking were 2, 4,
8, and 16 days respectively. Twenty-five of 30 patients (83%) showed
symptomatic improvement. Mean pre- and postoperative Karnofsky physical
performance scores were 55 and 85 respectively (P < 0.02). Small bowel
obstruction was due to adhesions in five patients. All patients with
intestinal obstruction had complete relief of their symptoms
postoperatively. 5-Hydroxyindolacetic acid levels decreased by 50 per
cent in all patients with follow-up determinations available. Aggressive
surgical exploration and tumor debulking could be performed with
significantly improved symptomatic outcome and relatively minor
complications. Longer follow-up is needed for assessment of effect on

Carcinoid tumors are very rare neoplasms, arising from enterochromaffin
cells, classified in Apud system, exhibiting an intermediate malignancy,
because of their long lasting clinical silence and low evolution to
advanced stage. At the same time, these features unfortunately cause a
high incidence of lymphatic and liver metastases, visible at first
diagnostic approach, which are also determined by aspecific symptoms and
signs, especially involving jejunal and ileal carcinoids, as the two
cases described, and by very frequent absence, in current clinical
practice, of pathognomonic carcinoid syndrome. Two carcinoids located
into the distal ileal ansa, strictly adjacent to the ileocecal valve,
are reported; the first tumor, accompanied by lymphonodal positivity,
the second by a solitary hepatic metastasis, requiring segmentectomy of
the liver, in addition to right hemicolectomy.

Minimally invasive transanal surgery for localized rectal carcinoid

Local excision is often fully justified for rectal carcinoid tumors.
However insufficient surgical field and difficult access to proximal
tumors have been drawbacks in performing pre-existing local excision
procedures. A novel local excisional technique called minimally invasive
transanal surgery (MITAS) has been experimented for local removal of
carcinoid tumors in the rectum. A specially designed anal retractor
connected to the Octopus retractor holder was used and an ENDO-stapler
allowed the simultaneous excision and anastomosis to be performed. Eight
patients with carcinoid tumors in the rectum (4 tumors in the upper
rectum) underwent MITAS. Median distance from anal verge to proximal
tumor was 6.5 cm (range, 5-12 cm). The median diameter of the tumor was
9 mm. Median operative time was 18.5 minutes and blood loss was minimal.
No analgesics were needed postoperatively, and there was no morbidity or
mortality. Full-thickness excision of the rectum was accomplished and
the tumors confined in the submucosa were demonstrated histologically to
be with free surgical margins. No recurrences have been observed with a
median follow-up period of 39 months. The technique facilitates total
excisional biopsy for rectal carcinoid tumors and reduces operative
time, blood loss and complications.

[Neuroendocrine tumors of the stomach. Surgery therapy and prognosis]

Gastric carcinoid tumors are rare lesions characterized by
hypergastrinemia that arise from enterochromaffin-like (ECL) cells of
the stomach. A classification system distinguishing three types of
gastric carcinoid tumors has been proposed: 1) tumors related to chronic
atrophic gastritis, 2) tumors associated with Zollinger-Ellison
syndrome, and 3) sporadic lesions. It is apparent that
hypergastrinemia-associated gastric carcinoids show a rather benign
biological behavior. Normo-gastrinemic sporadic lesions, on the other
hand, require an aggressive surgical management. We report seven
patients with gastric neuroendocrine tumors ("carcinoids"), who
underwent surgical treatment in our department between 1988 and 2000.
Surgical therapy included total gastrectomy with D2 lymphadenectomy in
two cases with type I tumors and for one patient with type III tumor.
One patient with a type II tumor was treated by distal subtotal
gastrectomy and another by antrectomy. A local excision was performed on
one patient with type I tumor. After a mean follow-up of 8 years, 5 of 7
patients are alive without recurrence.

Chemoembolization in the treatment of metastatic ileocolic carcinoid.

Carcinoid tumours are enigmatic, slow growing malignancies, which occur
most frequently (74%) in the gastrointestinal tract. Symptoms of the
carcinoid syndrome (flushing and diarrhoea) are infrequent, occurring in
approximately 10% of the patients with small bowel carcinoid. A
45-year-old patient with multiple liver metastases, diagnosed in 1994
with nonHodgkin's lymphoma after undergoing surgery for a distal ileal
tumour, was referred to us by the Department of Haematology. At that
moment the issue of a differential diagnosis with a carcinoid tumour
arose, due to the long evolution and lack of evidence to support the
initial diagnosis. The carcinoid syndrome was in fact present (the
patient experiencing flush after small amounts of alcohol and emotions)
and also we identified elevated values of 5HIAA. Reevaluation of the
histologic sections of the ileal tumour as well as an ultrasound guided
fine needle aspiration of an intrahepatic lesion confirmed the diagnosis
of "carcinoid tumour". This conclusion lead to new therapeutic options
for this patient. One of the main therapeutic options used in treating
multiple liver metastases from a carcinoid tumour is chemoembolization
and this case offered an excellent opportunity to present this therapy.
