Result of Breast Cancer Survival and Prognostic Factors at National Cancer Institute (Thailand) during 1992-1996
Abstract
Breast cancer is a common leading cancer in Thai women. A retrospective, non-randomized, analysis of 873 cases of breast cancer treated at the National Cancer Institute in Bangkok from June 1, 1992 to December 31, 1996 was made. Their medical records were reviewed to the date of last follow-up or the confirmation of death certificate. Data studied included the disease staging, primary tumor size, axillary Iymph node status, estrogen receptor (ER) and progesterone receptor (PR), histologic type and grading, systemic metastasis, marital status, education level, treatment and survival.
The per cent of patients classified by staging 1-4 were 8.1, 51.2, 29. 0 and 11.7 per cent respectively. Their mean age was 48.34 years, ranging 22-85 years. Chemotherapy was given in 72.6 per cent after surgery and in combined treatment with radiation in the cases of stages 2 and 3. Majority of histologic type was ductal carcinoma (80.9 per cent). The overall 5-year survival was 50.4 per cent. By the Anova test. over all survival was statistical significantly related to staging of cancer, size of primary tumor, number of involved axillary lymph nodes, histologic type and grading of tumor. systemic metastasis, marital status, patients' education, and types of treatment.
