Appendiceal malignant tumors among patients with acute appendicitis Background: Acute appendicitis can be the fi rst manifestation of an appendiceal tumor. Aim: To evaluate the incidence of appendiceal tumors among patients operated for acute appendicitis. Material and Methods: All patients operated for acute appendicitis between 1998 and 2008 and whose appendix had a pathological study were included. Survival was calculated using national death register databases. Results: Data from 6.093 patients was analyzed. A malignant tumor was found in 17 patients (0.3%). Eleven patients aged 23 ± 14 years had a carcinoid tumor, that was more commonly located distally, fi ve patients aged 66 ± 18 years had an adenocarcinoma, that was more commonly located proximally, and one patient had a non Hodgkin lymphoma. Curative surgery was carried out in all carcinoid tumors and 40% of adenocarcinomas. No patient had regional lymph node involvement. Five years survival of patients with carcinoid tumors was 100%. Conclusions: The fi nding of malignant tumor among patients with acute appendicitis is uncommon.

Subtotal gastrectomy for poorly differentiated and undifferentiated antral gastric cáncer Background: Total gastrectomy is recommended by some groups for poorly differentiated gastric cancer due to the multicentric nature of this tumor. Aim: To assess if subtotal gastrectomy achieves a good disease control in patients with undifferentiated or poorly differentiated gastric cancer. Material and Methods: Retrospective review of medical records of patients with undifferentiated or poorly differentiated gastric cancer, subjected to a subtotal gastrectomy between 1988 and 2006. Five years survival was calculated. Results: Fifty two patients aged 23 to 80 years were identifi ed (30 males). Three had undifferentiated and 49 poorly differentiated tumors. One patient had a positive proximal margin. After a median follow up of 52 months, fi ve years survival was 47%. Thirteen percent were lost from follow up. Conclusions: Five years survival of patients with undifferentiated or poorly differentiated gastric cancer and subjected to subtotal gastrectomy, was 47%.
