Trends in Axillary Management of Early Breast Cancer: a Questionnaire-Based Pattern of Practice Survey for India.

Surgical management of breast cancer (BC) has evolved from radical surgeries to conservative with better cosmetic and comparable oncological outcomes. For axillary staging, it has evolved from axillary lymph node dissection (ALND) to sentinel lymph node biopsy (SLNB). No detailed information exists in terms of the clinical practice pattern of surgical management of axilla for BC patients in India. A questionnaire-based survey was developed. The survey was done at the annual meeting of the Association of Breast Surgeons of India (ABSI) in November 2018. Responses were recorded and analysed by SPSS 23. One hundred twelve out of 400 (28%) responded to the survey. Half of the respondents were surgical oncologist and 36.6% were performing > 150 BC surgeries/year. The primary technique for axillary staging in node-negative BC was SLNB for 68.5% of respondents. Majority of surgeons (47%) reported performing SLNB by methylene blue dye only. Unavailability of radioisotope (46.7%) and lack of frozen section (26.7%) were reported as two major barriers for not performing SLNB. Twenty-three percent did perform SLNB in post-NACT setting. Only 15.8% have omitted completion ALND in Z0011 trial eligible SLN-positive patients. 45.9% skipped completion ALND in SLN positive with micro metastasis only. Many surgeons in India are adopting SLNB as a method of axillary staging into their clinical practice. However, large number of surgeons still believe in conservative approach, most probably due to unavailability of resources and lack of Indian data. Barrier identified in this survey may be useful for future development.
