Factors influencing the survival of patients with cancer of the stomach.
During the period 1969 through 1973, 332 male and 135 female patients diagnosed with stomach cancer were registered with the Cross Cancer Institute in Edmonton, Alberta. These patients were followed up to December 31, 1981. Therefore, we were able to observe eight year survival times for all patients. Rates for one to eight years of survival were calculated using the Kaplan-Meier method. The results showed poor survival experience for male and female patients, similar to survival reported in other countries. Stomach cancer in Alberta belongs to the ten most common cancers and a search for factors influencing survival is therefore important. A large number of environmental factors and factors pertaining to the patients' lifestyle, as well as clinical factors related to stage of disease and treatment were examined using Cox's proportional hazard model. Surgical treatment and the presence of metastases were found to be important determinants of survival for both sexes. In males, increased age and British ethnicity were associated with poor survival prospects. Relative hazards of dying are presented for various combinations of factors.
