Sentinel node in breast cancer as an indicator of quality in medical care: Evaluation of statistics in Colombia.

BACKGROUND Sentinel lymph node biopsy in breast cancer is considered the standard of staging in cases of clinically negative lymph nodes. Its omission in favor of axillary dissection generates significant morbidity. OBJECTIVE To determine the total number of sentinel node biopsy procedures in breast cancer in Colombia from 2017 through 2020, model and analyze them as if they were performed only in stage I breast cancer patients, and integrate their results into the concepts of quality of medical care. METHODS Search in a database of the Ministry of Health and Social Protection of Colombia with sentinel lymph node biopsy codes, and filters of breast cancer and year. Their results are contrasted with the number of cases in stage I of breast cancer. RESULTS Breast cancer TNM staging was reported in 22154 cases, 3648 stage I. In the same time frame, the number of sentinel lymph node biopsies for breast cancer in Colombia was 1045, 28.64% of the total cases reported in stage I. CONCLUSIONS Colombia is far from complying with the standard indicator of sentinel lymph node biopsy. It is recommended to concentrate breast cancer cases in hospitals that provide the conditions for its performance.
