Tumor-Infiltrating Lymphocyte Therapy or Ipilimumab in Advanced Melanoma.

Abstract Background: Immune checkpoint inhibitors and targeted therapies have dramatically improved outcomes in patients with advanced melanoma, but approximately half these patients will not have a durable benefit. Phase 1-2 trials of adoptive cell therapy with tumor-infiltrating lymphocytes (TILs) have shown promising responses, but data from phase 3 trials are lacking to determine the role of TILs in treating advanced melanoma. Methods: In this phase 3, multicenter, open-label trial, we randomly assigned patients with unresectable stage IIIC or IV melanoma in a 1:1 ratio to receive TIL or anti-cytotoxic T-lymphocyte antigen 4 therapy (ipilimumab at 3 mg per kilogram of body [...]

ASO Visual Abstract: Predictors of Sentinel Lymph Node Metastasis in Patients with Thin Melanoma-An International Multi-institutional Collaboration.

Abstract In this international, multi-institutional, retrospective cohort study of 676 patients with thin melanoma undergoing sentinel lymph node biopsy, only 7.8% of patients had a positive sentinel lymph node. Mitotic rate and Breslow thickness were predictive of nodal metastasis. Read Full Paper

Is a History of Optimal Staging by Sentinel Lymph Node Biopsy in the Era Prior to Adjuvant Therapy Associated with Improved Outcome Once Melanoma Patients have Progressed to Advanced Disease?

Abstract Introduction: Sentinel lymph node biopsy (SLNB) is important for staging in patients with primary cutaneous melanoma. Did having previously undergone SLNB also affect outcomes in patients once they have progressed to metastatic melanoma in the era prior to adjuvant therapy? Methods: Data were retrieved from the Dutch Melanoma Treatment Registry, a prospectively collected, nationwide database of patients with unresectable stage IIIC or IV (advanced) melanoma between 2012 and 2018. Melanoma-specific survival (MSS) was compared between patients with advanced cutaneous melanoma, previously treated with a wide local excision (WLE) or WLE combined with SLNB as initial treatment of their primary tumor. [...]

Five-Year Analysis of Adjuvant Pembrolizumab or Placebo in Stage III Melanoma.

Abstract Background In the previously reported primary analyses of this phase 3 trial, 12 months of adjuvant pembrolizumab resulted in significantly longer recurrence- and distant metastasis-free survival than placebo in patients with resected high-risk stage III melanoma. To confirm the stability of these benefits, longer-term data were needed. Methods We randomly assigned 1019 patients to receive 200 mg of pembrolizumab or placebo intravenously every 3 weeks for a total of 18 doses (approximately 1 year) and had previously reported data with a 15-, 36-, and 42-month median follow-up. We now report data at a median follow-up of 4.9 years. [...]

Neoadjuvant nivolumab + T-VEC combination therapy for resectable early stage or metastatic (IIIB-IVM1a) melanoma with injectable disease: study protocol of the NIVEC trial.

Abstract Background: Trials investigating neoadjuvant treatment with immune checkpoint inhibitors (ICI) in patients with melanoma have shown high clinical and pathologic response rates. Treatment with talimogene laherparepvec (T-VEC), a modified herpes simplex virus type-1 (HSV-1), is approved for patients with unresectable stage IIIB-IVM1a melanoma and has the potential to make tumors more susceptible for ICI. Combination ICI and intralesional T-VEC has already been investigated in patients with unresectable stage IIIB-IV disease, however, no data is available yet on the potential benefit of this combination therapy in neoadjuvant setting. Methods: This single center, single arm, phase II study aims to show an [...]

Diagnosis and treatment of Merkel cell carcinoma: European consensus-based interdisciplinary guideline – Update 2022.

Abstract Merkel cell carcinoma (MCC) is a rare skin cancer, accounting for less than 1% of all cutaneous malignancies. It is found predominantly in white populations and risk factors include advanced age, ultraviolet exposure, male sex, immunosuppression, such as AIDS/HIV infection, haematological malignancies or solid organ transplantation, and Merkel cell polyomavirus infection. MCC is an aggressive tumour with 26% of cases presenting lymph node involvement at diagnosis and 8% with distant metastases. Five-year overall survival rates range between 48% and 63%. Two subsets of MCC have been characterised with distinct molecular pathogenetic pathways: ultraviolet-induced MCC versus virus-positive MCC, which [...]
