OBJECTIVES: To review the patient characteristics and treatment methods of breast cancer patients at a tertiary hospital in India. METHODS: This study was a retrospective review of electronic medical records from a tertiary care hospital in Mumbai, India. Patients ≥18 years of age hospitalized for breast cancer treatment between Jan 2014 and May 2015 were included in the study. Descriptive and inferential statistics were used to analyze and compare differences between patients. RESULTS:  A total of 146 patients met the study criteria. Of these, 120 patients were in the age group of 18 to 64 years. The mean age for all the breast cancer patients was 51.07+13.34 years. The mean age was lowest for patients with private insurance (PI) while highest for patients with CGHS (CGHS=54.69+13.35 years, RGJAY=52.39+12.41 years, NI=46.59+16.43 years, PI=45.64+12.49 years). The majority of the patients (n=120, 82.2%) underwent a surgical procedure during their stay. The majority of the patients were subscribed to RGJAY payer scheme (RGJAY=97, 66.4%; CGHS=13, 8.9%; NI=22, 15.1%; PI=14, 9.6%). Abnormal growth was the most common reason for admission into the hospital (n=106, 72.6%). 49 (33.5%) patients with hypertension and 36 (24.6%) patients with diabetes were reported as major comorbidities during hospitalization. The majority of the patients had early stage breast cancer (108, 74.0%), while 16 (11.0%) patients had locally advanced breast cancer stage 2B and 22 (15.1%) patients had locally advanced breast cancer stage 3A to C. Of the total 120 patients that had surgery, majority of them (n=90) underwent a modified radical mastectomy (MRM) or a breast conservation surgery (n=10). CONCLUSIONS:  Majority of the breast cancer patients were diagnosed during the early stages of the disease and were subscribed to RGJAY scheme. The common reason for hospital admission was abnormal growth and the common procedure patients underwent was the MRM.
