Systemic Therapy for Melanoma: ASCO Guideline Update
Abstract Purpose: To provide guidance to clinicians regarding the use of systemic therapy for melanoma. Methods: American Society of Clinical Oncology convened an Expert Panel and conducted an updated systematic review of the literature. Results: The updated review identified 21 additional randomized trials. Updated recommendations: Neoadjuvant pembrolizumab was newly recommended for patients with resectable stage IIIB to IV cutaneous melanoma. For patients with resected cutaneous melanoma, adjuvant nivolumab or pembrolizumab was newly recommended for stage IIB-C disease and adjuvant nivolumab plus ipilimumab was added as a potential option for stage IV disease. For patients with unresectable or metastatic cutaneous melanoma, nivolumab plus relatlimab [...]
European consensus-based interdisciplinary guideline for invasive cutaneous squamous cell carcinoma. Part 1: Diagnostics and prevention-Update 2023.
Abstract Invasive cutaneous squamous cell carcinoma (cSCC) is one of the most common cancers in white populations, accounting for 20% of all cutaneous malignancies. Overall, cSCC mostly has very good prognosis after treatment, with 5-year cure rates greater than 90%. Despite the overall favourable prognosis and the proportionally rare deaths, cSCC is associated with a high total number of deaths due to its high incidence. A collaboration of multidisciplinary experts from the European Association of Dermato-Oncology (EADO), the European Dermatology Forum (EDF), the European Society for Radiotherapy and Oncology (ESTRO), the European Union of Medical Specialists (UEMS), the European [...]

Adjuvant therapy for stage II melanoma: the need for further studies.
Abstract Immunotherapy with checkpoint inhibitors has revolutionised the outcomes for melanoma patients. In the metastatic setting, patients treated with nivolumab and ipilimumab have an expected 5-year survival of> 50%. For patients with resected high-risk stage III disease, adjuvant pembrolizumab, nivolumab or dabrafenib and trametinib are associated with a significant improvement in both relapse-free survival (RFS) and distant metastasis-free survival (DMFS). More recently neoadjuvant immunotherapy has shown very promising outcomes in patients with clinically detectable nodal disease and is likely to become a new standard of care. For stage IIB/C disease, two pivotal adjuvant trials of pembrolizumab and nivolumab have [...]

Systemic LRG1 expression in melanoma is associated with disease progression and recurrence.
Abstract The response rates upon neoadjuvant immune checkpoint blockade (ICB) in stage III melanoma are higher as compared with stage IV disease. Given that successful ICB depends on systemic immune response, we hypothesized that systemic immune suppression might be a mechanism responsible for lower response rates in late-stage disease, and also potentially with disease recurrence in early-stage disease. Plasma and serum samples of cohorts of patients with melanoma were analyzed for circulating proteins using mass spectrometry proteomic profiling and Olink proteomic assay. A cohort of paired samples of patients with stage III that progressed to stage IV disease (n [...]
Baseline ultrasound and FDG-PET/CT imaging in Merkel cell carcinoma.
Abstract Background: Merkel cell carcinoma (MCC) is a cutaneous tumor with a high tendency to metastasize, and a significant proportion of patients have metastases at first presentation. This study aims to determine the value of baseline ultrasound (US) and 18 fluorodeoxyglucose-positron emission tomography/computed tomography (18 FDG-PET/CT) imaging in both patients with clinically localized MCC (Stage I/II) and patients who present with palpable lymph nodes (Stage III). Methods: This retrospective cohort included 135 MCC patients who underwent baseline US (with fine needle aspiration cytology (FNAC)) and/or FDG-PET/CT imaging between 2015 and 2021. Results: Of the 104 patients with clinically localized [...]
IFN-γ signature enables selection of neoadjuvant treatment in patients with stage III melanoma.
Abstract Neoadjuvant ipilimumab + nivolumab has demonstrated high pathologic response rates in stage III melanoma. Patients with low intra-tumoral interferon-γ (IFN-γ) signatures are less likely to benefit. We show that domatinostat (a class I histone deacetylase inhibitor) addition to anti-PD-1 + anti-CTLA-4 increased the IFN-γ response and reduced tumor growth in our murine melanoma model, rationalizing evaluation in patients. To stratify patients into IFN-γ high and low cohorts, we developed a baseline IFN-γ signature expression algorithm, which was prospectively tested in the DONIMI trial. Patients with stage III melanoma and high intra-tumoral IFN-γ scores were randomized to neoadjuvant nivolumab [...]
Surgical outcomes of lymph node dissections for stage III melanoma after neoadjuvant systemic therapy are not inferior to upfront surgery.
Abstract Background: Neoadjuvant systemic therapy has shown promising results in the treatment of high-risk stage III melanoma; however, the effects on surgery are currently unknown. This study aims to compare the surgical outcomes, in terms of postoperative complications, postoperative morbidity, duration of surgery and textbook outcomes, of patients with high-risk stage III melanoma who received neoadjuvant systemic therapy followed by lymph node dissection with patients who received an upfront lymph node dissection. Methods: In this retrospective cohort study, patients with high-risk stage III melanoma treated with neoadjuvant anti-PD1 and anti-CTLA4 in the OpACIN (NCT02437279) and OpACIN-neo (NCT02977052) trial between [...]
