Popis: Background: Sentinel lymph node (SLN) dissection was designed to minimize side effects of lymph node surgery but still offer outcomes of axillary lymph node dissection. Aims and Objectives: Our study is designed to determine whether SLN resection achieves the same therapeutics outcome as complete axillary dissection but with fewer side effects for node-negative axilla in clinicoradiologically operable breast cancer patients. Materials and Methods: Duration-based prospective observational study was carried out at the General Surgery and Surgical Oncology Department at Government Medical College and Hospital, Aurangabad with a duration of 2 ½ years from July 2019 to January 2022. A total of 36 patients of breast cancers with stages T1-T2, N0 with clinically and radiologically negative axilla from July 2019 to January 2022 duration were included in our study. Results: When the histopathological status of axillary lymph nodes was compared to the histopathology of SLNs it was seen that out of 36 patients, the histopathology of sentinel node was positive in 10 patients (10/36) however the rest of the axilla was positive in 6 cases and negative in 4 cases and the histopathology sentinel node was negative in 26 patients out of 36 cases (26/36) however the rest of the axilla was also negative in 24 cases and positive in 2 cases. Conclusion: SLN biopsy using methylene blue dye alone is a highly reliable and predictable technique to stage the axilla in breast cancer patients as this study shown a low false-negative rate (7.69%). This technique may help to avoid complete axillary lymph node dissection in sentinel node-negative patients thereby minimizing the morbidity of axillary lymph node dissection. This study demonstrates that sentinel node localization is possible with methylene blue dye alone.
