Therefore, sentinel lymph node biopsy (SLNB) has been assessed, with contradictory findings thus far.
Sentinel lymph node biopsy for squamous cell carcinoma skin#
The SLNB procedure has shown a high sensitivity rate, but the pooled sensitivity and false-negative rate were worse in SLNB alone trials than in SLNB validation trials. Merkel cell carcinoma (MCC), squamous cell carcinoma (SCC), pigmented epithelioid melanocytoma (PEM), and other rare skin neoplasms have a well-known risk to. Introduction: Cutaneous squamous cell carcinoma (cSCC) shows malignant behaviour in 3-4 of patients with locoregional metastases and a poor prognosis, metastases that are difficult to predict clinically. The subgroup with high methodological quality showed a mean identification rate of 95.4% for SLNB validation trials and 94.2% for SLNB alone trials, and mean sensitivity of 91.0% for SLNB validation trials and 84.2% for SLNB alone trials. The pooled identification rate, sensitivity, false-negative rate, negative predictive value, and accuracy were 95.2%, 86.3%, 13.7%, 94.2%, and 95.0%, respectively. Pooled values for the sentinel lymph node identification rate, sensitivity, false-negative rate, negative predictive value, and accuracy were calculated.Ī total of 16 studies (987 patients) was included. Objective: This study tested the long-term outcomes of sentinel lymph node biopsy (SLNB) for oral tongue squamous cell carcinoma (SCC) during the transition from validation to application phase. The PubMed database was searched for studies published before October 31, 2012. Neck management in patients with early-stage, clinically node-negative oral squamous cell carcinoma (OSCC) remains a matter of discussion. The aim of this study was to evaluate the role of sentinel lymph node (SLN) biopsy in anal squamous cell carcinoma. The purpose of this study was to evaluate the efficacy of sentinel lymph node biopsy (SLNB) in early head and neck squamous cell carcinoma (HNSCC). There remains a need for a better method to diagnose inguinal lymph node metastases which is minimally invasive, accurate and avoids unnecessary irradiation to the groin with its associated significant co-morbidity.
