As a result of their previous experience with mitomycin C at high discontinuous doses in advanced gastric cancer, the authors studied its role as an adjuvant for locally advanced cases after surgical complete resection. Results from 70 evaluable patients are presented. Patients were allocated randomly to receive mitomycin C, 20 mg/m2 I.V. direct once every 6 weeks, four courses, or a placebo. After a follow-up period of 250 weeks, seven patients of treatment arm and 23 controls have already relapsed (p less than 0.001). Toxicity was moderate and controllable by symptomatic measures. The authors consider this investigation a positive contribution in the field of adjuvant therapy of gastric cancer.
Two cases of papillary‐cystic neoplasm of the pancreas are reported in women aged 22 and 23 years. The patient in the first case presented with acute abdominal pain and hemoperitoneum. This form of presentation has not been previously reported. This type of pancreatic tumor is very rare, exclusively affecting young women, and has a good prognosis despite its various histologic features, which suggest a malignant appearance. The authors consider this neoplasm as having an acinar origin because in the cells of one of the patients we observed ultrastructurally the presence of abundant rough endoplasmatic reticulum with formation of annulate lamellae and a few prezymogen granules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
