Effects of continuous hyperthermic peritoneal perfusion on prognosis of gastric cancer with serosal invasion.

OBJECTIVE: To evaluate the effects of continuous hyperthermic peritoneal perfusion (CHPP) together with standard chemotherapy on the prognosis of patients with gastric cancer invading the serosa. DESIGN: Retrospective study. SETTING: University hospital, Japan. SUBJECTS: 174 patients who had undergone curative resection for gastric cancer invading the serosa (T3) between 1980 and 1989, 78 of whom had been randomised to be treated with CHPP after operation and 96 who received standard chemotherapy. INTERVENTIONS: CHPP was done immediately after operation; 8-10 l fluid containing 80-100 mg/m2 mitomycin C was perfused at a rate of 100-200 ml/minute, and inflow and out flow temperatures were maintained at 44-45 degrees C and 40-42 degrees C, respectively. This was followed by a standard regimen of mitomycin C and 1-(2-tetrahydrofuryl)-5-fluorouracil/uracil (1:4) (UFT). The control group received the standard regimen only. MAIN OUTCOME MEASURES: Five year survival and patterns of recurrence in three groups: no lymph node metastases, 1-9, and 10 or more. RESULTS: Only in the group with 1-9 lymph node metastases was there an appreciable but not significant difference in 5 year survival: 66% compared with 44% (p = 0.084). The mean disease free survival for patients with peritoneal metastases was 30 months in the CHPP group compared with 23 months among the controls. CONCLUSION: CHPP improved prognosis in patients with T3 gastric cancer who had only 1-9 metastatic lymph nodes.

Clinicopathologic differences between carcinoma in the gastric remnant stump after distal partial gastrectomy for benign gastroduodenal lesions and primary carcinoma in the upper third of the stomach.

BACKGROUND: This study evaluated the prognosis of patients with carcinoma in the gastric remnant stump after distal gastrectomy for benign disease (stump cancer). METHODS: Twenty patients with resected stump cancer were studied and compared with 266 patients with resected primary cancer in the upper third of the stomach (primary cancer). RESULTS: The percentages of lymph nodes with metastases located at the lesser curvature and the left gastric artery, respectively, were 50.0% and 25.2% in patients with primary cancer and 15.0% and 5.0% in patients with stump cancer. In patients with remnant gastric cancer, lymph node metastases at jejunal mesentery near anastomotic site were found in 2 of 20 (10.0%). The 5-year survival rates were 62.1% and 52.5% for patients with curatively resected primary cancer (n = 203) and stump cancer (n = 17), respectively, and there was no statistical difference between the two groups. There was a distinct difference in terms of patterns of recurrence between patients with curatively resected primary cancer and those with stump cancer. The percentages of peritoneal and hematogenic metastases, respectively, were 40.6% and 31.3% in primary cancer and 0% and 83.3% in stump cancers. CONCLUSION: The lymph flow from the remnant stomach seems to be changed by the initial operation, and as a result, in stump cancer, metastatic lymph nodes are located at different places from those associated with primary cancer. Even when curative surgery is performed in patients with stump cancer, it is important to follow up patients and check for possible metastasis to the liver.

Accessory nerve neuroma presenting as recurrent jugular foramen syndrome.

We report a patient with spontaneous recovery and recurrence of a jugular foramen syndrome secondary to an accessory nerve neuroma. He showed sudden onset of unilateral palsy of the ninth, tenth and eleventh cranial nerves in 1982. He recovered almost fully and in 1990 the palsies recurred. MRI revealed a small mass in the right jugular foramen. The tumour was resected via suboccipital craniectomy, and diagnosed as a neuroma of the eleventh cranial nerve.

Flow cytometric analysis of the DNA content of tumor cells in cases of gastric cancer in the upper third of the stomach and in the remnant stomach.

Thirteen samples of gastric tumors that had developed in the remnant stomach (remnant gastric cancer) were compared with 63 samples of primary gastric tumors located in the upper third of the stomach (primary gastric cancer) by both clinicopathologic and flow cytometric analysis. The depths of invasion of all these tumors corresponded to the mucosa, submucosa, or muscularis propria layers and the histological stages were stages I, II, or III. There was no significant difference between the two groups of samples either histopathologically or clinically (the 5-year survival rates were 74.6% for patients with remnant gastric cancer and 90.4% for patients with primary gastric cancer). DNA aneuploidy was encountered in 23.1% of the cases of remnant gastric cancer and in 33.3% of the cases of primary gastric cancer. Little difference was found in the S-phase fractions between tumors and normal gastric mucosa of the upper third of the stomach and the remnant stomach. Thus, while the environments in the upper third of the stomach and in the remnant stomach are very different, histopathological and biological characteristics of adenocarcinomas that developed in the remnant stomach are very similar to those of adenocarcinomas in the upper third of the stomach.

Radiochemosensitivity and expression of p53 in patients with esophageal cancer treated by absolute noncurative resection.

The aim of this study was to investigate the relationship between the expression of p53 protein and radiochemosensitivity in patients with advanced esophageal cancer. We analyzed the expression of p53 protein by an immunohistochemical method in tumors from 28 patients with advanced esophageal cancer who had been treated by absolute noncurative resection. Four patients died from postoperative complications. Fourteen of the remaining 24 patients were treated with postoperative radiochemotherapy. The expression of p53 protein was detected in tumors from 16 of 28 patients (57.1%). The mean survival period was 16.4 months for 14 patients treated with radiochemotherapy, as compared to 6.9 months for 10 patients who were not treated with radiation therapy (P = 0.112). In the case of the 14 patients treated with radiochemotherapy, the mean survival period was 24.7 months for seven patients with p53-negative tumors while it was only 8 months for seven patients with p53-positive tumors. However, difference was not statistically significant (P = 0.149). Postoperative radiochemotherapy prolonged the survival of some patients with noncuratively operated esophageal tumors that were p53-negative. However, the enhanced survival was not statistically significant.
