Bimonthly regimen of high-dose leucovorin, infusional 5-fluorouracil, epirubicin and cisplatin (modified ECF) as adjuvant chemotherapy in resected gastric adenocarcinoma.

BACKGROUND: The administration of the de Gramont regimen in combination with cisplatin and epirubicin (modified ECF) has previously been reported as a treatment for advanced gastric cancer, but here we report this regimen combination in an adjuvant setting for the first time. METHODS: Forty-eight patients with curatively resected gastric cancer were treated. Each 2-week cycle consisted of epirubicin (50 mg/m(2)), cisplatin (50 mg/m(2)), 5-fluorouracil (5-FU) IV bolus (400 mg/m(2)) and 5-FU IV (2,400 mg/m(2)) over 46 h plus leucovorin IV (400 mg/m(2)) over 2 h. Postoperative chemoradiotherapy was also administered to the patients when indicated. We retrospectively reviewed the patients who were treated with modified ECF. RESULTS: The median disease-free survival (DFS) was 40.7 months and the 1-, 3- and 5-year DFS rates were 78.5, 55.7 and 44.6%, respectively. The most common grade 3-4 toxicities were hematological and gastrointestinal. CONCLUSION: A modified ECF regimen may be an effective and convenient treatment with tolerable toxicities for the adjuvant treatment of gastric cancer. It may provide an alternative regimen to the standard ECF when a continuous ambulatory infusion pump is not feasible or not preferred by the patient.

Incidence of thyroid dysfunction and thyroid cancer in renal transplant recipients: a single center experience.

BACKGROUND: The prevalence of thyroid cancer in renal transplant population has not been widely studied, and there is no consensus on the management of thyroid cancer in transplant patients. The aim of this study was to evaluate changes in thyroid hormone levels and investigate the incidence of the thyroid cancer after renal transplantation. MATERIALS AND METHODS: From October 1989 to April 2007, 122 renal allograft recipients that were being followed underwent thyroid ultrasonography to determine nodules together with thyroid hormone levels. Ultrasound-guided fine-needle aspiration biopsy (FNAB) was performed to the nodules > 10 mm or those with 8-10 mm diameter but with calcifications. RESULTS: One hundred and eight patients (88.5%) had normal thyroid function. None of the patients had overt hypothyroidism, 2 had subclinical hypothyroidism, 10 subclinical thyrotoxicosis, and 2 low T3 syndrome. Mean thyroid volume was 14.2 +/- 7.2 ml. In all, 91.8% was diagnosed with goiter (n = 112). Seventy-two thyroid nodules were detected in 49 kidney allograft recipients (single nodule in 30, multiple in 19 patients). Eighty-four biopsy samples were reported as benign (n = 21, 87.5%), 8 as suspicious (n = 2, 8.3%), and 4 as inadequate (n = 1, 4.1%). After surgery, one of the patients (0.8%) with suspicious FNAB was reported as papillary thyroid carcinoma. CONCLUSION: Because of the high incidence of thyroid dysfunction in transplant patients, screening of thyroid function should be a part of follow-up. Our results suggest that although frequency of nodules is increased in kidney transplant patients, prevalence of thyroid cancer is slightly, but not significantly, higher than that of the normal population.

Effects of hepatectomy and arginine enriched diet on colonic mucosa originated inflammatory cytokines.

AIM: To assess the effects of arginine-enriched diet and partial hepatectomy in rats on gut-originated inflammatory cytokines. METHODS: Of 24 rats, Group 1 and 2 animals were fasted 24 hours before surgery, Group 3 and 4 animals received regular plus arginine-enriched diet(AED). Group 2 and 4 animals had undergone 30% hepatic resection. Leukotriene B4 (LT B4) levels were detected in colonic mucosa and mucosal perfusates immediately after resection. Mean leukocyte counts (MLC) were detected also in the mucosa. RESULTS: In the basis of fasting situation regardless hepatectomy, all MLC were lower in Group 3 and 4 but LTB4 levels both in mucosa and perfusate were higher. On hepatectomy based comparison there was not any statistically significant difference between groups but mucosal perfusate LTB4 levels. But when hepatectomy added on fasted animals MLC levels were lower than fed by AED + sham operation. LTB4 levels were insignificant in both perfusate and mucosa. When hepatectomy added on AED animals (Group 4), MLC decreased and mucosal LTB4 increased when they compared with fast without hepatectomy Group 1. CONCLUSIONS: AED prior to extra-intestinal operations may trigger inflammatory cascade and complications via leucocyte degradation and LTB4.

Ectopic pancreas presenting with intractable diarrhea: case report.

Ectopic pancreas is an uncommon congenital anomaly, which is usually found incidentally in clinical practice. It presents with nonspecific gastrointestinal symptoms like epigastric pain and dyspepsia and rarely with the clinical findings of obstructive jaundice or intestinal obstruction, or it may mimic gastrointestinal system cancer. Herein, we describe a case of ectopic pancreas in the duodenum, which was the cause of the intractable diarrhea. In our patient, upper gastrointestinal endoscopy and endoscopic ultrasonography revealed a 1.5 cm submucosal lesion, which was umbilicated centrally with a normal in appearance overlying mucosa. Endoscopic biopsy of the lesion was normal. Pathological examination of the lesion after surgical excision was compatible with ectopic pancreas. After total excision of the lesion, the clinical findings of the patient normalized. Ectopic pancreas presenting with diarrhea has not been reported previously in the literature.
