Abstract

In Indian females, breast cancer is the most common cancer with a late stage of presentation leading to one-third of patients undergoing modified radical mastectomy (MRM). Our study is undertaken to find out predictors of level III axillary lymph node metastasis in breast cancer and who needs complete axillary lymph node dissection (ALND). Retrospective study of 146 patients who undergone MRM or breast-conserving surgery (BCS) with complete ALND at Kidwai Memorial Institute of Oncology was done, and data was analyzed to find out the frequency of level III lymph nodes and the demographic relation and its relation to positive lymph nodes in level I + II. Positive metastatic level III lymph node was found in 6% of patients, with the median age of the patient in our study with level III positivity was 48.5 years with 63% pathological stage II with 88% perinodal spread (PNS)– and lymphovascular invasion (LVI)–positive. Involvement of level III lymph node was associated with gross disease in level I + II lymph node having more than four lymph node-positive and with pT3 stage or more which has higher chances of level III lymph node involvement. Level III lymph node involvement, though rare in early-stage breast cancer, is associated with larger clinical and pathological sizes (T3 or more), more than 4 lymph node-positive in level I + II and with PNS and LVI. Hence, based on these results, we recommend that for inpatient with more than 5-cm tumor size and those with the gross disease in axilla, complete ALND is recommended.
