Lymphatic mapping and sentinel lymph node biopsy in squamous cell carcinoma of the lower lip

High-risk cutaneous squamous cell carcinoma and the emerging role of sentinel lymph node biopsy: A literature review

“…A review of all case series reporting SLNB in cSCC is detailed in Table IV. 13,18,28,[41][42][43][44][45][46][47][48][49][50][51][52] Our systematic review identified an overall positive rate for SLNB of 13.9% (32 of 231 patients) and a false-negative rate of 4.6% (10 of 215 patients) in cSCC. The authors usually stated that patients had high-risk factors for lymph node involvement.…”

Sentinel node biopsy for squamous cell carcinoma of the head and neck

“…Superficial dermis and epidermis is devoid of lymphatic drainage, making squamous cell carcinoma less likely to spread via lymphatics. Sentinel node biopsy of high risk cutaneous squamous cell carcinomas is currently under investigation by several groups, however the number of cases reported to date is not adequate to draw a conclusion [30][31][32]. We have also attempted to do sentinel node biopsies for a subgroup of cutaneous squamous cell carcinomas perceived to be at high risk based on traditional criteria [33].…”

“…Even though intraoperative evaluation with frozen section examination of suspected lymph nodes is inaccurate, this method may help identifying the cases in which neck dissection should extend to levels II and III 11 . Investigation of sentinel lymph node allows better intraoperative evaluation, which is frequently found as level I in lip tumors 12 .…”
