Prevalence of teaching sentinel lymph node biopsy for breast cancer in general surgery residency programs.
OBJECTIVE
Sentinel lymphadenectomy (SLNB) for the evaluation of clinically negative lymph nodes in women with invasive breast cancer is rapidly gaining acceptance within the surgical community. The purpose of this study was to document the prevalence of teaching SLNB to residents in general surgery training programs in the United States.


METHODS
The Fellowship and Residency Electronic Interactive Database (FREIDA) was searched for a listing of all general surgery residency programs. A short questionnaire was mailed to the program director of each residency program listed. The program directors were asked whether general surgery residents are taught the technique of performing SLNB for breast cancer, and how the procedure is performed at their institutions.


RESULTS
Of the 255 surgical programs listed in FREIDA, 191 or 75% responded to the survey. Of responding programs, 92% are currently teaching surgical residents SLNB, whereas 4% plan on adding SLNB to the curriculum within the next academic year. A total of 74% of programs are performing SLNB as part of an organized hospital protocol, whereas 40% routinely follow SLNB with an axillary node dissection. A total of 89% of the programs use both sulfur colloid radioisotope and isosulfan blue dye, whereas 7% use dye alone, and 4% use only radioisotope.


CONCLUSIONS
The practice of performing SLNB for the purpose of detecting occult nodal metastases in breast cancer is being taught at most surgery training programs in this country. In the less than 6 years since the modification of this technique for the treatment of breast disease, it has become the standard of care for treating women with invasive breast cancer with clinically negative axillary lymph nodes at training hospitals in the United States.
