Introduction: Management of brain metastases (BM) is witnessing marked advancement worldwide and modern technologies with better outcomes are gradually being adopted in developing countries. However, data regarding current practice in this field is lacking from the Indian subcontinent prompting us to plan the current study.
Materials and Methods: A retrospective, single institutional audit was performed on 112 patients with solid tumors metastasizing to the brain treated over the last 4 years at a tertiary care center in eastern India, of which 79 were ultimately evaluable. Demography, patterns of incidence, and overall survival (OS) were determined.
Results: The prevalence of BM was 5.65% among all patients with solid tumors. The median age was 55 years with a slight male preponderance. Lung followed by breast were the most common primary subsites. Multiple BM (54%), left-sided (61%), and frontal lobe lesions (54%) were the more common. Metachronous BM was found in 76% of patients. All patients received whole brain radiation therapy (WBRT). The median OS for the entire cohort was 7 months (95% confidence interval [CI]: 4 - 19 months). The median OS for lung and breast primaries were 6.5 and 8 months and for recursive partitioning analysis (RPA) classes I, II, and III the OS were 11.5, 7, and 3 months, respectively. Median OS did not differ by number of or other sites of metastases.
Conclusions: The outcomes from our series about BM from solid tumors in patients from eastern Indian are in congruence to those available in the literature. Patients with BM are still largely treated with WBRT in resource-limited settings.
