Effect of non-sentinel metastasis on adjuvant treatment decisions and survival in Z0011 eligible non-screened detected breast cancer population. Ecancermedicalscience 2022; 15:1324. [PMID: 35047075 PMCID: PMC8723749 DOI: 10.3332/ecancer.2021.1324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Indexed: 11/30/2022] Open
Abstract
Background The Z0011 trial results have shown that axillary lymph node dissection (ALND) can be avoided in cT1-2 patients undergoing breast conservation surgery with 1–2 metastatic sentinel lymph nodes (SLNs). We compared the clinicopathological characteristics of the Z0011 eligible non-screen detected breast cancer patients’ cohort with the Z0011 trial study population. Additionally, we have explored the effect of non-sentinel metastasis on adjuvant treatment decisions and survival. Methods The details of early breast cancer (EBC) patients fulfilling Z0011 eligibility criteria were retrieved from a prospectively maintained database (2013–2017) and electronic medical records. We used Statistical Package for the Social Sciences 25 and Stata V15 for the data analysis. Results 128/194 (66%) sentinel lymph node biopsy positive patients had fulfilled the Z0011 inclusion criteria. Compared to the Z0011 study, our cohort patients were younger, with more aggressive disease (higher T2, Grade 3), had a higher rate of macrometastasis (82.8% versus 58.8%) and non-SLN metastasis (48% versus 27%). The information gained by ALND had changed decisions for chemotherapy in 3% and no change of radiotherapy in Z0011 eligible patients. Further nodal positivity in completion ALND was not significantly associated with overall survival (p = 0.86) and disease-free survival (p = 0.5). Conclusion Z0011 eligible Indian EBC patients are significantly different from the Z0011 study population, with younger age of presentation, higher grade, a higher rate of both SLN macro metastasis and non-SLN positivity. The impact of non-sentinel metastasis on adjuvant treatment decisions and survival is minimal.

Indian J Surg Oncol 2021; 12:401-407. [PMID: 34295086 DOI: 10.1007/s13193-021-01334-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2020] [Accepted: 04/20/2021] [Indexed: 02/06/2023] Open
Abstract
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.
