It has a high NPV and can potentially identify at-risk lymphatic basins outside the traditional selective neck dissection levels even in well-lateralized lesions. SLNB for early OCSCC is technically feasible in an Australian setting. However, there are subgroups of patients at higher risk, for whom sentinel lymph node biopsy (SLNB) might be useful. The metastatic potential is generally low. Of these, one patient had a positive sentinel node outside of the ipsilateral supraomohyoid neck dissection template. Aims: Cutaneous squamous cell carcinoma (SCC) is the second most common skin cancer. The negative predictive value (NPV) of SLNB was 100%, with 40% having a sentinel node identified outside the field of planned neck dissection on lymphoscintigraphy. No false-negative sentinel nodes were identified using selective neck dissection as the gold standard. A median of three (range: 1-14) sentinel nodes were identified on lymphoscintigraphy, and all sentinel nodes were successfully retrieved, with 50% having a pathologically positive sentinel node. High-risk cutaneous squamous cell carcinoma (SCC) is associated with an increased risk of metastases. The study was done from 2013-15 in 94 patients in a large cancer centre. All patients underwent SLNB followed by immediate selective neck dissection (levels I-III).Ī total of 30 patients were diagnosed with an early clinically node-negative OCSCC (seven cT1 and 23 cT2), with the majority located on the oral tongue. Our aim was to evaluate the feasibility and role of sentinel lymph node (SLN) biopsy using methylene blue dye alone in identifying occult lymph node metastases in early oral cancer (cT1, T2, and cN0). We performed a prospective cohort study consisting of 30 consecutive patients with cT 1 - 2 N 0 OCSCC referred to the Head and Neck Cancer Service, Westmead Hospital, Sydney, between 20. We sought to assess the technical feasibility of SLNB and validate its accuracy against that of END in an Australian setting. Sentinel lymph node biopsy (SLNB) has become an alternative option to elective neck dissection (END) for early oral cavity squamous cell carcinoma (OCSCC) outside of Australia.
