Abstract
AbstractBackgroundSentinel lymph node biopsy (SLNB) helps to determine accurate pathological stages and facilitates strategies for regional disease control in melanoma. However, whether the number of biopsied sentinel lymph nodes (SLNs) influences the patients' survival is rarely investigated.MethodsAcral or cutaneous melanoma patients with no history of nodal disease who received SLNB in Fudan University Shanghai Cancer Center (FUSCC) from January 1, 2017, to December 31, 2021 were retrospectively enrolled. Clinicopathological variables including Breslow index, ulceration, number of positive SLNs, SLN/non‐SLN status were analyzed. The pathologic nodal (pN) stage and pathological stage were defined.ResultsA total of 381 eligible patients were enrolled in this study, of whom 132 (34.7%) patients were diagnosed with SLN‐positive. The median number of biopsied SLNs was 2 (range: 1 to 20). Different numbers of biopsied SLNs did not influence the release‐free survival (RFS) of the general patients. However, patients with >2 SLNs had a longer RFS than those with 1–2 SLNs in T4, N1a group and those who rejected complete lymph node dissection (CLND).ConclusionsIn patients with T4 melanomas, N1a melanomas and those that did not undergo a CLND, the prognosis of those with three or more SLNs retrieved seemed to be improved.
