Time to reconsider the role of sentinel lymph node biopsy in melanoma
Abstract The Multicenter Selective Lymphadenectomy Trials indicate that there are no overall or melanoma-specific survival advantages to performing sentinel lymph node biopsy (SLNB) followed by immediate completion lymph node dissection compared with wide excision and observation for patients with positive sentinel nodes. These results make SLNB solely a staging procedure. The role of SLNB in the management of patients with melanoma deserves reappraisal. The potential marginal benefit of SLNB beyond the clinical and pathologic features of the melanoma has not been well studied. The use of sentinel lymph node status alone to accept and stratify patients into trials or [...]
Adjuvant radiotherapy after salvage surgery for melanoma recurrence in a node field following a previous lymph node dissection.
Abstract Background and objectives: Adjuvant radiotherapy (RT) can be given to melanoma patients following salvage surgery for node field recurrence after a previous regional node dissection, but the value of this treatment strategy is poorly documented. This study evaluated long-term node field control and survival of patients treated in this way in an era before effective adjuvant systemic therapy became available. Methods: Data for 76 patients treated between 1990 and 2011 were extracted from an institutional database. Baseline patient characteristics, treatment details and oncological outcomes were analysed. Results: Adjuvant RT with conventional fractionation (median dose 48 Gy in 20 [...]
Uncovering the complex relationship between balding, testosterone and skin cancers in men.
Abstract Male-pattern baldness (MPB) is related to dysregulation of androgens such as testosterone. A previously observed relationship between MPB and skin cancer may be due to greater exposure to ultraviolet radiation or indicate a role for androgenic pathways in the pathogenesis of skin cancers. We dissected this relationship via Mendelian randomization (MR) analyses, using genetic data from recent male-only meta-analyses of cutaneous melanoma (12,232 cases; 20,566 controls) and keratinocyte cancers (KCs) (up to 17,512 cases; >100,000 controls), followed by stratified MR analysis by body-sites. We found strong associations between MPB and the risk of KC, but not with androgens, [...]

Has the advent of modern adjuvant systemic therapy for melanoma rendered sentinel node biopsy unnecessary?
Abstract The prognostic value of sentinel node biopsy (SNB) is well established and SNB was therefore adopted as a requirement for pathological staging of melanomas>1 mm thick in the American Joint Committee on Cancer (AJCC) 8th edition. Consequently, a negative SNB status became an eligibility criterion for clinical trials of adjuvant systemic therapy in resected stage IIB/C melanoma. However, since the Keynote 716 trial demonstrated an improvement in relapse-free survival (RFS) in patients with Stage IIB/C melanoma, all of whom had SNB staging, some have argued that SNB is no longer required for patients with T3 and T4 primary [...]
