Evolutive and prognostic aspects in gastric cancer. Analysis of 189 cases.

The cases of 189 patients treated at the Surgery Service for gastric carcinoma from January 1960 to December 1978 and followed until April 1984 were reviewed in terms of evolutive behavior. Correlations between sex, age, duration of symptoms, site of tumors, lymph node metastases, stage of tumors, operability, resectability, treatment and survival were attempted. With respect to age, of the patients not operated on, survival was longer for more advanced age; the opposite occurred for the group of patients who were operated on. The impairment of lymph nodes was decisive in shortening survival; men were affected more than women and had a worse prognosis. When the tumors were located in the proximal third of the stomach, the survival rate was longer than when they were located in the distal portion and middle third of the stomach. Patients who had experienced digestive symptoms for a long time survived longer than those with a short history. It was concluded that the main prognostic factor was resectability and, regardless of any other variables, only patients from the group submitted to gastric resection survived more than 5 years.
