Background: Mucosal melanoma is an aggressive melanoma with poor prognosis. We assessed efficacy of pembrolizumab in patients with advanced mucosal melanoma in KEYNOTE-001 (NCT01295827), -002 (NCT01704287), and -006 (NCT01866319).
Methods: Patients received pembrolizumab 2 mg/kg every 3 weeks (Q3W) or 10 mg/kg Q2W or Q3W. Response was assessed by independent central review per RECIST v1.1.
Results: 1567 patients were treated and 84 (5%) had mucosal melanoma. Fifty-one of 84 were ipilimumab-naive. In patients with mucosal melanoma, the objective response rate (ORR) was 19% (95% CI 11-29%), with median duration of response (DOR) of 27.6 months (range 1.1 + to 27.6). Median progression-free survival (PFS) was 2.8 months (95% CI 2.7-2.8), with median overall survival (OS) of 11.3 months (7.7-16.6). ORR was 22% (95% CI 11-35%) and 15% (95% CI 5-32%) in ipilimumab-naive and ipilimumab-treated patients.
Conclusion: Pembrolizumab provides durable antitumour activity in patients with advanced mucosal melanoma regardless of prior ipilimumab.

Recent advances in oncology research have highlighted the promising synergy between low-dose radiation therapy (LDRT) and immunotherapies, with growing evidence highlighting the unique benefits of the combination. LDRT has emerged as a potent tool for stimulating the immune system, triggering systemic antitumor effects by remodeling the tumor microenvironment. Notably, LDRT demonstrates remarkable efficacy even in challenging metastatic sites such as the liver (uveal) and brain (cutaneous), particularly in advanced melanoma stages.

Introduction: The purpose of this European multicenter study was to describe and assess the characteristics, diagnosis, management, and recurrence of oral malignant melanoma at different European oral and maxillofacial surgery centers.
Materials And Methods: This study was based on a systematic computer-assisted database that allowed the recording of data for all primary oral mucosal melanomas treated in the involved surgical units across Europe between January 1, 2003 and December 31, 2022. The following data were recorded for each patient: gender, age, site, TNM staging, metastases, symptoms, imaging features, histopathological features, treatment, complications, recurrence, follow up, and survival.

The dissemination of tumor cells with ensuing metastasis is responsible for most cancer-related deaths. Cancer vaccines may, by inducing tumor-specific effector T cells, offer a strategy to eliminate metastasizing tumor cells. However, several obstacles remain in the development of effective cancer vaccines, including the identification of adjuvants that enhance the evolvement and efficacy of tumor-specific T cells.

Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses. However, detailed mechanisms of such processes remain unclear.

Background: Sinonasal mucosal melanoma (SNMM) is a rare and aggressive malignancy associated a poor prognosis, prognosis. It is by delayed presentation and nonspecific symptoms. The incidence of SNMM is low, with and there are challenges in achieving local control and managing distant metastases.
