BACKGROUND: Breast cancer accounts for one-fourth of cancer cases seen in female patients in Kerala, India. Results of a retrospective analysis of breast cancer in Kerala are presented in this article. METHODS: Case records of 449 patients with breast carcinoma treated during 1983-1984 were reviewed. Survival analysis was done by the Kaplan-Meier product limit method. The survival curves were compared by the log-rank test. A forward stepwise procedure with the Cox proportional hazards regression analysis was performed to identify factors influencing survival. RESULTS: The overall 5-year survival rate was 40%. The 5-year survival rates were 85% for patients with T1, 63% for T2, 32% for T3, and 21% for T4 lesions. Those with N0 disease had a 68% 5-year survival rate. The survival rates were 90% for patients with Stage I, 65% for Stage II, 33% for Stage III, and 6% for Stage IV disease. On multivariate analysis, the following factors were found to significantly influence survival: response to treatment (P < 0.001), stage (P < 0.01), and regional nodal involvement (P < 0.05). CONCLUSIONS: Two-thirds of patients with advanced-stage disease on presentation seem to account for the poor overall survival. Early detection of breast cancer by breast self-examination and physician breast examination should be encouraged in developing countries to improve treatment results in breast cancer.
