Factors predicting survival in thick melanoma: Do all thick melanomas have the same prognosis?

Background: It is unknown whether all thick melanomas share the same prognostic features. We present a large, multi-institutional study on thick melanoma, evaluating for factors prognostic of survival.

Methods: We queried the database of the Sentinel Lymph Node Working Group for patients with thick melanoma (>4 mm) who had a sentinel lymph node biopsy from 1993 to 2018.

Sentinel Lymph Node Biopsy Is Prognostic in Thickest Melanoma Cases and Should Be Performed for Thick Melanomas.

Background: Sentinel lymph node biopsy (SLNB) is recommended for intermediate thickness melanoma, but for thick melanoma, guidelines are less definitive about the use of SLNB in this population. We present a study on thick melanoma evaluating for prognostic factors.

Patients And Methods: The Sentinel Lymph Node Working Group database was queried for thick (> 4 mm) melanoma cases that had a SLNB from 1993 to 2018.

Preoperative Ultrasound Assessment of Regional Lymph Nodes in Melanoma Patients Does not Provide Reliable Nodal Staging: Results From a Large Multicenter Trial.

Objective: To assess whether preoperative ultrasound (US) assessment of regional lymph nodes in patients who present with primary cutaneous melanoma provides accurate staging.

Background: It has been suggested that preoperative US could avoid the need for sentinel node (SN) biopsy, but in most single-institution reports, the sensitivity of preoperative US has been low.

Methods: Preoperative US data and SNB results were analyzed for patients enrolled at 20 centers participating in the screening phase of the second Multicenter Selective Lymphadenectomy Trial.

Recurrence of Melanoma After a Negative Sentinel Node Biopsy: Predictors and Impact of Recurrence Site on Survival.

Background: Factors that predict melanoma recurrence after a negative sentinel lymph node biopsy (SLNB) are not well-defined. We evaluated melanoma recurrence patterns, factors prognostic for recurrence, and the impact of recurrence on outcomes after a negative SLNB.

Methods: The Sentinel Lymph Node Working Group database was evaluated from 1996 to 2016 for negative SLNB melanoma patients.

Completion lymphadenectomy for a positive sentinel node biopsy in melanoma patients is not associated with a survival benefit.

Background: Completion lymph node dissection (CLND) for sentinel lymph node (SLN) disease in melanoma patients is debated. We evaluated the impact of CLND on survival and assessed for predictors of nonsentinel node metastasis (positive CLND).

Methods: Positive SLN melanoma patients were retrospectively identified in the Sentinel Lymph Node Working Group database.

Perspectives in melanoma: Meeting report from the Melanoma Bridge (30 November-2 December, 2017, Naples, Italy).

Metastatic melanoma represents a challenging clinical situation and, until relatively recently, there was an absence of effective treatment options. However, in 2011, the advanced melanoma treatment landscape was revolutionised with the approval of the anti-cytotoxic T-lymphocyte-associated protein-4 checkpoint inhibitor ipilimumab and the selective BRAF kinase inhibitor vemurafenib, both of which significantly improved overall survival. Since then, availability of new immunotherapies, especially the anti-programmed death-1 checkpoint inhibitors, as well as other targeted therapies, have further improved outcomes for patients with advanced melanoma.

Phenotype characterization of human melanoma cells resistant to dabrafenib.

In the present study, the phenotype of melanoma cells resistant to dabrafenib (a B-RAF inhibitor) was investigated, to shed more light on melanoma resistance to B-RAF inhibition. Melanoma cells resistant to dabrafenib were generated using 3 different cell lines, A375, 397 and 624.38, all carrying B-RAFV600E, and they were characterized by cytofluorometric analysis, Ion Torrent technology, immunofluorescence and biochemistry.

Long-Term Survival after Complete Surgical Resection and Adjuvant Immunotherapy for Distant Melanoma Metastases.

Background: This phase III study was undertaken to evaluate the efficacy of an allogeneic whole-cell vaccine (Canvaxin™) plus bacillus Calmette-Guerin (BCG) after complete resection of stage IV melanoma.

Methods: After complete resection of ≤5 distant metastases, patients were randomly assigned to BCG+Canvaxin (BCG/Cv) or BCG+placebo (BCG/Pl). The primary endpoint was overall survival (OS); secondary endpoints were disease-free survival (DFS), and immune response measured by skin test (ClinicalTrials.

Impact of Time Between Diagnosis and SLNB on Outcomes in Cutaneous Melanoma.

Background: Hypothetically, delay between melanoma diagnosis and SLNB could affect outcomes, either adversely by allowing growth and dissemination of metastases, or beneficially by allowing development of an anti-melanoma immune response. Available data are conflicting about the effect of SLNB delay on patient survival. Our objective was to determine whether delay between initial diagnosis and SLNB affects outcomes in patients with cutaneous melanoma.

Completion Dissection or Observation for Sentinel-Node Metastasis in Melanoma.

Background: Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.

Electrochemotherapy efficacy evaluation for treatment of locally advanced stage III cutaneous squamous cell carcinoma: a 22-cases retrospective analysis.

Background: Extensive squamous cell carcinoma has few therapeutic options. In such cases, electrochemotherapy involving electroporation combined with antineoplastic drug appears to be a new potential option and may be considered as an alternative treatment. The aim of this retrospective single-center study was to evaluate electrochemotherapy efficacy in treatment of locally advanced stage III squamous cell carcinoma, in which surgical procedures would have entailed wide tissue sacrifice.

Correlation between previous treatment with BRAF inhibitors and clinical response to pembrolizumab in patients with advanced melanoma.

The optimal sequencing of targeted treatment and immunotherapy in the treatment of advanced melanoma is a key question and prospective studies to address this are ongoing. Previous observations suggest that treating first with targeted therapy may select for more aggressive disease, meaning that patients may not gain full benefit from subsequent immunotherapy. In a single-center retrospective analysis, we investigated whether response to pembrolizumab was affected by previous BRAF inhibitor therapy.

The Impact of Smoking on Sentinel Node Metastasis of Primary Cutaneous Melanoma.

Background: Although a well-established causative relationship exists between smoking and several epithelial cancers, the association of smoking with metastatic progression in melanoma is not well studied. We hypothesized that smokers would be at increased risk for melanoma metastasis as assessed by sentinel lymph node (SLN) biopsy.

Methods: Data from the first international Multicenter Selective Lymphadenectomy Trial (MSLT-I) and the screening-phase of the second trial (MSLT-II) were analyzed to determine the association of smoking with clinicopathologic variables and SLN metastasis.

Future perspectives in melanoma research: meeting report from the "Melanoma Bridge": Napoli, December 3rd-6th 2014.

The fourth "Melanoma Bridge Meeting" took place in Naples, December 3-6th, 2014. The four topics discussed at this meeting were: Molecular and Immunological Advances, Combination Therapies, News in Immunotherapy, and Tumor Microenvironment and Biomarkers. Until recently systemic therapy for metastatic melanoma patients was ineffective, but recent advances in tumor biology and immunology have led to the development of new targeted and immunotherapeutic agents that prolong progression-free survival (PFS) and overall survival (OS).

Assessing a novel immuno-oncology-based combination therapy: Ipilimumab plus electrochemotherapy.

Melanoma is responsible for most skin cancer-related deaths and is one of the most common cancers diagnosed in young adults. In melanoma, tumors can become established by activation of the negative regulator of cytotoxic T lymphocytes (CTLs), CTL antigen-4 (CTLA-4). Ipilimumab blocks the interaction of CTLA-4 with CD80/CD86 and augments T-cell activation and proliferation.

Electrochemotherapy in melanoma patients: a single institution experience.

Aim: This study was undertaken to update the outcome of the treated lesions with electrochemotherapy (ECT) plus intravenous injection of bleomycin in patients with in-transit disease or distant cutaneous metastases in melanoma patients.

Patients & Methods: 89 patients with relapsed and refractory cutaneous melanoma metastases or in-transit disease were submitted to 126 treatments of ECT.

Results: 34 patients (38.

Report from the second MIB (Melanoma Independent Board) Conference, 27-28 October 2014.

The second Melanoma Independent Board (MIB) meeting was held in Rome, Italy from 27-28 October 2014. The themes of this meeting were once again innovation and sustainability and it brought together health providers, researchers, government representatives, journalists, patients, and pharmaceutical representatives.

Vemurafenib beyond progression in a patient with metastatic melanoma: a case report.

The prognosis of metastatic melanoma has changed markedly in recent years because of the advent of newer targeted therapies such as BRAF inhibitors. However, the response to BRAF inhibitor therapy is frequently nondurable in patients with advanced melanoma. Novel approaches are thus needed to overcome resistance to these agents and to improve the management of advanced melanoma patients after disease progression.
