e11506 Background: The incidence of breast cancer is rising in India. It presents at a younger age in Indian population as compared to the western countries. Methods: This is a retrospective review of all breast cancer patients less than 40 years of age treated in single tertiary care center from June 2006 to June 2011. The aim was to assess the factors that may influence clinical outcome and prognosis including demographics, clinical characteristics, surgical and pathological findings and the treatment given. Clinical data was collected from medical records and histopathology reports. Independent variables like age, stage at presentation, surgery type, chemotherapy, radiation, tumour size, grade, nodal status, no. of positive nodes, perinodal extension, lymphovascular extension, ER, PR and Her2 neu were analysed. Results: Out of a total of 613 patients, 91 were under 40 years of age, corresponding to a prevalence of 14.8%. Median age was 35 years with the youngest being 23 years old. Maximum patients were in the age group of 36-40 years. Lymphovascular emboli was positive in 42 patients (48.8%) and perinodal extension was positive in 36 patients (41.8%). 30 patients(34.8%) had ER positivity, while 39 patients (45.3%) had PR positivity. Her 2 neu receptors were positive in 20 patients (23.2%). 39 patients were triple negative (45.3%). The median follow up period for all the patients was 28 months with the DFS being 76.1% and OS being 88.3%. In univariate analysis, factors significantly associated with survival were stage at presentation (p value- 0.026), presence of lymhovascular emboli (p value- 0.019) and presence of perinodal extension (p value- 0.007 ).Grade of the tumour also correlated with survival , however it was not statistically significant (p value- 0.086). Statistical analysis was done with SPSS 17. Conclusions: The incidence of breast cancer in younger women in India is high with increased number of triple negative patients. Overall survival is quite similar to that of the western population. Longer follow up and more studies are required to confirm this finding.
