Abstract

ABSTRACTTumor infiltrating lymphocytes (TILs) invade and disrupt melanoma cells and their clinical roles remain controversial. In this study, we aimed to determine the clinical significance of the TILs status in cutaneous melanoma patients (CMPs). Of 750 CMPs enrolled into this study 486 (64.8%) had lesions with TILs. The patients with TILs more likely had nodular histology, presence of histological regression, and absence of regional lymph node involvement. However, its presence was not associated with outcome. In conclusion, presence of TILs may be only an independent predictor for absence of nodal involvement but it is not associated with recurrence and survival in CMPs.
