Disease-free survival pattern in breast cancer patients in India treated in a single institution.

e12030 Background: This study elucidates data from a 5 year retrospective study evaluating survival rates and prognostic factors in breast carcinoma patients in a private cancer set up in south India. Methods: 1046 patients who were treated between years 2003 to 2008 were analyzed. Clinical data including stage, histopathology type, age, node positivity, treatment plan, chemotherapy regimen, ER/ PR and Her2 Neu status, type of surgery etc were abstracted in a database. Five year disease free survival, local failure free survival and distant failure free survival was calculated using Kaplan Meier survival curves. Log rank mantel hazel tests were used to compare two survival curves. Results: Local recurrence was seen in 4% and distant metastases in 22% of the study sample. 62% of patients presented with early breast cancer (AJCC Stage I, II and IIIA). 85.6% of early and 73.1% of locally advanced breast cancers were disease free at 5 years (p<0.001).90.6% of early and 82.4% of locally advanced breast cancers had distant failure free survival at 5 years (p=0.001). Local failure free survival was 96.1% in both early and locally advanced breast disease at 5 years.94.9% of her 2 negative and 83.5% Her 2 positive were disease free at 5 years (p=0.001). 5 years progression free survival was 91.5% for breast conservation surgery vs 84.1% for mastectomy with axillary clearance (p=0.01). 75.4% with triple negative status and 80.8% non triple negative receptor status had 5 years DFS. Conclusion: This is a first report of survival patterns of breast cancer patients treated in a single centre in India. High early stage patient numbers and high median disease free survival times could be because of improvement in screening and treatment of breast cancer in a developing country like India.
