Hispanic ethnicity does not impact survival in gastric adenocarcinoma. However, histology, metastasis pattern, tumor localization, and other clinical parameters differ sufficiently to warrant further investigation into the epidemiology, pathogenesis, and molecular biology of gastric cancer in this population.

Approximately two-thirds of patients with locally recurrent rectal cancer can be resected for cure. Preoperative carcinoembryonic antigen and an R0 resection margin were the only significant predictors of overall survival. p53, bcl-2, and ki-67 did not impact survival outcomes.

Local excision and postoperative radiotherapy result in adequate local control of early stage (Tis and T1) adenocarcinoma of the rectum. Higher rates of recurrence were seen in patients with T2 and T3 tumors, especially in those with positive margins.
