33 cases of cancer of the gastric stump after gastrectomy for peptic ulcer observed between 1963 and 1972 are reviewed. In 26 patients the average interval between operation and carcinoma detection was over 20 years. No cases of carcinoma occurred in less than 10 years. All patients came too late for surgery, since they had attributed their symptoms to the previous operation. The gradual increase in the gastric-cancer risk of operated patients with time suggests a continuous carcinogenic influence. Regurgitation of duodenal contents through the Billroth II anastomosis seems to be the most important cause of postoperative atrophic gastritis, which is now considered by many authors to be a condition predisposing to gastric cancer. Gastric resection patients should be regarded as a high gastric-cancer risk group. The periodic use of modern procedures for early gastric cancer detection in this group of patients is therefore justified.

Clinical aspects and management of hereditary non-polyposis colorectal cancer (HNPCC).

Hereditary non-polyposis colorectal cancer (HNPCC) is an autosomical dominant trasmitted disease phenotypically defined according to the "Amsterdam criteria" as follows: at least 3 affected relatives, one of whom first degree relative of other two, at least two successive generations affected. Important cardinal features are: 1) prevalent proximal location of cancers (above splenic flexure); 2) multiple synchronous or methachronous large bowel cancers; 3) early age of onset (<50 years); 4) presence of extracolonic cancers (endometrium, stomach, urinary tract, skin). The treatment is essentially surgical and total colectomy with ileo-rectum anastomosis is already proposed as standard procedure with annual endoscopic examination of retained rectum. The screening of individuals at risk, so determined by the analysis of pedigree or the results of molecular tests, must be performed every 1-2 years by colonoscopy starting around the age of 25 years. In this review are described and analysed the spectrum of the disease with particular attention to the frequency and characteristics of extracolonic cancers. Moreover, the guidelines of the surveillance and screening are reported following the data of the literature and as proposed by the International Collaborative Group (ICG-HNPCC).

CA 19-9 assay in patients with extrahepatic cholestatic jaundice.

Serum concentrations of the CA 19-9 tumour marker were determined in 35 patients with histologically proven bilio-pancreatic malignancies associated with obstructive jaundice and in 35 patients with benign extrahepatic jaundice due to choledocholithiasis. At a cut-off level of 37 U/ml the sensitivity of this assay was 82.8%, but the specificity was very low (45.7%). Thus CA 19-9 can not be employed to differentiate between malignant and benign extrahepatic jaundice. Serial samples of CA 19-9 were achieved in 7 patients with benign and in 6 patients with malignant biliary obstruction, before and after the disappearance of jaundice. Serum concentrations of this tumour-antigen returned to normal concurrently with the bilirubin values only in patients with benign obstruction, remaining unchanged in all cases of malignancies. The data suggest that patients with extrahepatic jaundice should be evaluated by other examinations or by collecting serial samples for this assay.
