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%.

No association between serum D Dimer levels and lymph node involvement among patients with gastric cancer Background: D Dimer levels can be predictors of lymph node involvement in gastric cancer. Aim: To evaluate the association between D Dimer levels and lymph node involvement among patients with gastric cancer. Material and Methods: In 32 patients with gastric cancer, aged 38 to 86 years (24 males), subjected to a curative surgery, D Dimer was measured in the preoperative period. Its levels were associated with the number of regional lymph nodes involved and the tumor stage, according to the pathological report of the surgical piece. Results: There was no signifi cant correlation between D Dimer levels and the number of involved lymph nodes (r = 0.18, p = NS). Conclusions: In this series of patients with gastric cancer, there was no association between serum D Dimer levels and the number of involved regional lymph nodes.
