Absence of Granzyme B Positive Tumour-Infiltrating Lymphocytes in Primary Melanoma Excisional Biopsies is Strongly Associated with the Presence of Sentinel Lymph Node Metastasis
Abstract
Background: Sentinel Lymph Node (SLN) status is strongly related to clinical outcome in melanoma patients. In this study we investigated the possible association between the presence of activated and/or suppressive Tumour Infiltrating Lymphocytes (TILs) and SLN status in clinically stage I/II melanoma patients.
