The first draining lymph node (SLN) basin of the primary tumour is the target of sentinel lymph node biopsy (SLNB), a diagnostic staging procedure.
He undergoes a technetium-99m [99mTc]-labelled radio tracer peritoneal injection as part of his standard SLNB operation, which is followed by photographically and SECT-CT imaging. The discovered SLNs are indicated for surgical excision and undergo histologist analysis based on these imaging results. Early-stage oral squamous cell carcinoma has been reliably staged by a standard SLNB method in clinically negative cervix (OSCC). However, a well-known drawback emerges when the SLN is close to the injection site for the tracer. In these situations, it can be challenging to discern between the tracer injection site and the SLN due to the injection site hot spot's ability to hide the nearby SLN (shine-through phenomenon). Thus, technical advancement is required to raise the diagnostic efficacy of SLNB in early OSCC.
