This review traces the history of sentinel lymph node biopsy in cutaneous melanoma, highlighting its prognostic value and future innovations.
Sentinel lymph node biopsy (SLNB) has transformed the management of cutaneous melanoma, emerging as a cornerstone in evaluating regional lymphatic spread while minimizing surgical morbidity. From its theoretical foundation laid by Cabanas to its refinement and clinical validation through landmark trials, SLNB has evolved into a standard of care with significant prognostic value. This review traces the historical trajectory of SLNB, analyzes current guidelines and controversies and explores future directions. Novel imaging technologies, such as indocyanine green fluorescence and augmented reality-assisted mapping, promise to enhance accuracy and reduce invasiveness. Furthermore, the advent of effective systemic therapies and neoadjuvant protocols is reshaping the therapeutic landscape, potentially redefining the role of SLNB in melanoma management. As precision medicine advances, SLNB remains an essential procedure, with its utility continually redefined by technological innovation and evolving oncologic strategies.
