Multicenter analysis of the surgical management and adjuvant therapy of patients with melanoma and a positive sentinel lymph node biopsy.

Introduction: Complete lymph node dissection (CLND) was the standard practice for patients with melanoma and a positive sentinel lymph node biopsy (SLNB) until the results of 2 clinical trials published in 2016 and 2017 demonstrated that it did not improve melanoma-specific survival (MSS). However, it continues to be performed in some scenarios. No studies have ever been published on lymph node management after a positive SLNB in the routine clinical practice in our setting.

Histological deep margins in cutaneous squamous cell carcinoma of the scalp and risk of recurrence.

Background: Consensus is lacking on adequate deep histological margins in cutaneous squamous cell carcinoma (cSCC). Deep clearance for tumours located on the scalp is limited by anatomic constraints.

Objective: To determine whether clear but close deep histological margins (<1 mm) confer a higher risk of recurrence in cSCCs of the scalp treated by wide local excision, compared to deep histological margins ≥1 mm.
