This study of 783 patients with histologically confirmed gastric carcinoma has confirmed the importance of several previously recognized patient- and tumor-related characteristics related to prognosis and identified some new ones. Of the tumor-related factors, the ones that showed the strongest relationship to survival following curative gastric resection were tumor stage, histologic type, breach of lymph-node capsule, sinus histiocytosis, and gross appearance. Of the tumor- and patient-related factors, the ones that showed the strongest relationship to survival from time of diagnosis of surgically noncurable disease were status of primary, liver metastasis, serum bilirubin level, ascites, extent of tumor burden, and weight loss. The effect of treatment with 5-fluorouracil (5-FU) on survival duration was at best only minimal. Only those patients who received two or more cycles of 5-FU therapy had survival advantage over the remaining patients. The use of regression analysis has made it possible to make predictions of the prognosis of the patients. These predictions could be used in future studies to determine comparability of prognosis of various groups included in different studies and different arms of a randomized study.

The records of 43 patients with histologically proved primary gastric sarcoma treated at M. D. Anderson Hospital and Tumor Institute between 1945 and 1975 were reviewed. Weight loss, abdominal pain, and hematemesis or melena were the most common symptoms, and palpable epigastric mass was the most common physical sign. Ninety-five percent of the gastric tumors were leiomyosarcomas. The median survival time and the five-year survival for the 29 patients who had curative gastrectomy were 33 months and 38%, respectively. Morphologic and histologic factors that adversely influenced the length of disease-free interval and survival following curative surgery included 1) primary tumor 8 cm or greater in diameter, 2) tumor extension to serosa of the stomach, and 3) low grade of differentiation of the primary tumor. Seventy-seven percent of recurrences in patients with curative tumor resection occurred within two years of resection of the primary. Of the 17 patients with advanced disease who received chemotherapy, two (15%) had objective tumor regression of greater a median survival time of eight months for patients who failed to respond. New approaches that may improve the results of treatment of gastric sarcoma are discussed.

We present an unusual pseudotumor that formed in reaction to self-administered intramuscular injections of an anabolic steroid, nandrolone decanoate (Deca-Durabolin) in a young soldier. The histopathologic features which closely mimicked several malignant neoplasms could have led to an incorrect diagnosis of malignancy and unnecessary extensive surgery. To our knowledge, this phenomenon has not been previously reported.
