Vascular endothelial growth factor and basic fibroblast growth factor in patients with squamous cell oesophageal cancer.

It is suggested that vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) play an important role in tumor-induced angiogenesis. The purpose of this study was to estimate the correlation between VEGF and bFGF levels and tumor pathological status according to pTNM classification in patients with squamous cell oesophageal cancer. A group of 25 healthy controls and 32 consecutive patients with oesophageal cancer were included in this study. Serum VEGF and bFGF levels were determined by enzyme-linked immunosorbent assay (Quantikine R&D Systems). Serum VEGF and bFGF levels were significantly elevated in the patient groups (VEGF: 146.0 pg/ml, 79.0-386.3 pg/ml vs. 38.0 pg/ml, 6.5-135.1 pg/ml, p<0.005, and bFGF: 5.2 pg/ml, 1.2-10.6 pg/ml vs. 2.06 pg/ml, 0.07-4.0 pg/ml, p<0.02 Fisher test). The highest correlation between serum VEGF and bFGF levels were found in patients with advanced cancers, especially with: T4, N1, and M1 factors. The VEGF and bFGF levels were significantly higher in patients with pT4 (p<0.01). Patients with N1 lymph node invasion, compared with N0 factor, have higher levels of angiogenetic factors (p<0.04). Also in patients with advanced cancers with liver metastases the serum levels VEGF and bFGF were significantly higher (M1 vs. M0, VEGF p<0.001 and bFGF p<0.05). Consecutive monitoring of VEGF and bFGF serum levels may be a useful prognostic marker for patients with squamous cell oesophageal cancer.

Circulating anti-p53 antibodies in esophageal cancer patients.

Circulating anti-p53 protein antibodies (p53-Abs) have been detected in some cancer patients. The aim of the study was to determine the presence of circulating anti-p53 protein antibodies and their clinical significance in patients with esophageal carcinoma. Serum specimens from 75 consecutive patients with squamous cell carcinomas and 10 healthy subjects were studied. Enzyme linked immunosorbent assay (ELISA--Pharma Cell) was used to detect p53-Abs. At the time of diagnosis 20 (26.6%) of 75 analyzed patients had positive result in the p53-Abs test, but not any of the healthy subjects. The positive rate was 25% (1/4) cases in stage I, 41% (10/24) cases in stage IIA, 0% (0/8) cases in stage IIB, 28% (8/28) cases in stage III and 9% (1/11) cases in stage IV. In respect of tumour differentiation, cases graded as G1, G2 and G3 were positive in 28.5% (4/14), 25.9% (7/27) and 26.4% (9/34), respectively. There was no correlation between presence of p53-Abs and stage, rumour differentiation, lymph nodes metastases, tumour size, patient age and sex. In conclusion, the results of the present study indicate that serum p53-Abs did not correlate with cliniocopathologic feature of esophageal carcinoma.

[Carcinoid tumor in the retroperitoneal space].

Authors present a rare case of the pancreatic carcinoid. Diagnosis was based on clinical examination, ultrasonography, CT, and histopathological evaluation. The patient was operated on twice: (Whipple's procedure with the right hemicolectomy and then Roux-Y anastomosis). During follow-up the liver metastases appeared. The patient was treated with chemotherapy. She died 19 month after operation because of neoplastic dissemination.

[Stomach and esophageal neoplasm. Changes over 16 years in clinical materials].

Increasing prevalence of adenocarcinoma of the esophagus and esophago-gastric junction has been reported. The aim of the study was to determine whether this phenomenon is reflected in the cohort of patients referred for surgery to our institution. Clinical and pathological records of patients with adenocarcinoma of the stomach (n = 433) or gastro-esophageal junction (n = 302), and squamous cell carcinoma of the esophagus (n = 266) were reviewed from 1981 to 1996. Yearly prevalence of carcinoma of the gastric cardia in comparison to carcinoma of (a more distal) stomach has not changed, ranging 19-46%. From 1981 to 1984 out of 58 gastric resections, 14 (24%) total gastrectomies were done, whereas from 1993 to 1996 total gastrectomies were performed in 104 out of 138 (75%) patients with gastric cancer (p < 0.001). In the first 4 years of the study period adenocarcinoma of the cardia and/or esophagus was found in 19% of all patients with esophageal and junctional tumors, while in the last 4 years,-in 30%. Resection rates for gastric and cardiac cancers have not changed significantly, 75-100% and 21-65% respectively. Resection rate for carcinoma of the esophagus increased from 50% (17/34) to 79% (53/67) (p = 0.006, test chi2). Increasing rate of total gastrectomies can be explained by a trend towards more proximal localisation of the primary gastric tumors and/or clinical application of Laurén classification for the choice of operative procedure. Higher resection rate for carcinoma of the esophagus is a result of increasing experience of the surgical team, improvement in preoperative staging, new palliative modalities, and application of preoperative chemo-/radiotherapy.

[Complications of endoscopic sphincterotomy].

The aim of the study is an analysis of the complications among the patients who underwent endoscopic sphincterotomy. In years 1991-1996 in our Department 412 patients underwent endoscopic sphincterotomy. Bile ducts stones, acute bile pancreatitis, papilla Vateri stricture and the postoperative bile fistula were the indications for the procedure. Complications occurred in 37 patients (12 of them were operated on). One patient died due to duodenal perforation. GI bleeding, acute pancreatitis, common bile duct perforation, recurrence of the stricture and missing the concrement in the duct were the main complications. Endoscopic sphincterotomy remains the recommended method in describe cases.

[Comparison of the usefulness of ultrasonography and computed tomography in diagnosis of acute necrotizing pancreatitis].

The aim of this paper is to evaluate the sensitivity and specificity of ultrasound and computed tomography imaging in necrotizing acute pancreatitis. Since 01'95 till 12'96 we treated 36 patients with acute pancreatitis. They were diagnosed by US and contrast enhanced CT. 15 patients were intraoperatively classified as necrotizing pancreatitis. US done several times before operations positively predicted only 8 cases as having necrosis (sensitivity 53.3%) and in 7 patients the extension of its spread (specificity 87.5%). Preoperative CT positively predicted 13 cases of necrosis (sensitivity 86.6%) and the extension of its spread was properly stated in 7 patients (sensitivity 46.6%). 4 times preoperative CT was done twice. Contrast enhanced CT is better than US in predicting of the existence of pancreatic necrosis but it is not in evaluation of the extension of necrosis spread.

[Comparison of combined (endoscopic sphincterotomy + laparoscopic cholecystectomy) and classical treatment of obstructive jaundice in the course of cholelithiasis].

UNLABELLED: Since August 1993 till December 1996, 672 patients with the gallstone disease were submitted to the laparoscopic cholecystectomy (LC). In 78 (11.7%) of them, the endoscopic sphincterotomy (ES) was performed before LC for the treatment of the coexistent obstructive jaundice caused by bile duct stones (Group I). ES was successful in 70 patients (90%). The laparoscopic cholecystectomy was done after the bilirubinemia reached the level within the normal ranges. This period (4 days to 35 days) was dependent on the level of hyperbilirubinemia at presentation. In 12 cases both procedures were performed at the same time. LC was successful in 67 patients (96%). The mean period between ES and LC was 2.7 days. The mean time of hospital stay was 6.3 days. In other 52 patients open cholecystectomy with T drainage was done for the treatment of the gall stone disease complicated by the obstructive jaundice (Group II). Comparing the two group of patients, the significantly shorter time of treatment and hospital stay as well as the lower incidence of complications was observed in Group I. CONCLUSION: ES and LC in patients with the obstructive jaundice caused by stones results in lower morbidity and shorter time of treatment when comparing with patients treated by classical open cholecystectomy with T drainage.
