Kim: Response to letter to editor: indocyanine green fluorescent image-guided inguinal sentinel node biopsy for vulvar cancer: criteria and intraoperative challenges
I greatly appreciate the questions on our recent video article [1] by Iavazzoet al. [2].
Regarding the frozen section of the sentinel lymph node and completing lymphadenectomy in the case of a positive frozen section, we usually send the sentinel lymph nodes for the frozen sections, and we do not complete an inguinofemoral lymphadenectomy even in the case of a positive frozen section if no definitive evidence of lymph node metastasis in preoperative imaging studies (computed tomography [CT], magnetic resonance imaging, and/or positron emission tomography-CT) exists.
Even if some possibility of cancer metastasis to the residual lymph nodes exists, we think that complete inguinal lymphadenectomy is not needed because we have to perform radiotherapy on the inguinal area in the case of a positive frozen section. Once again, I would like to thank the authors for their questions.
