Background: Tumor heterogeneity is a hurdle to effective therapy, as illustrated by the 'mixed responses' frequently seen in immunotherapy-treated patients. Previously, AXL+ tumor cells were identified to be highly resistant to targeted therapy, whereas more differentiated MITF+ tumor cells do respond to RAF and MEK inhibitors.

Patients And Methods: In this study, we analyzed tumor heterogeneity and explored the presence of the previously described AXL+ or MITF+ melanoma subpopulations in metastatic tissues by NanoString gene expression analysis, single-cell RNA sequencing and multiplex immunofluorescence.

Background: The impact of the order of treatment with checkpoint inhibitors or BRAF/MEK inhibitors on the development of brain metastases in patients with metastatic unresectable V600-mutant melanoma is unknown. The SECOMBIT trial examined the impact of the order of receipt of these treatments in such patients.

Methods: In this three-arm trial, we reviewed patients without brain metastases who received the BRAF/MEK inhibitors encorafenib and binimetinib until they had progressive disease followed by the immune checkpoint inhibitors ipilimumab and nivolumab (arm A); or treatment with ipilimumab and nivolumab until they had progressive disease followed by encorafenib and binimetinib (arm B); or treatment with encorafenib and binimetinib for 8 weeks followed by ipilimumab and nivolumab until they had progressive disease followed by retreatment with encorafenib arm binimetinib (arm C).

Background: Previous results from this trial showed longer overall survival after treatment with nivolumab plus ipilimumab or with nivolumab monotherapy than with ipilimumab monotherapy in patients with advanced melanoma. Given that patients with advanced melanoma are living longer than 7.5 years, longer-term data were needed to address new clinically relevant questions.

Third-generation tyrosine kinase inhibitors are the first-line gold standard in treating advanced non-small-cell lung cancer bearing common mutations, but data documenting clinical efficacy in uncommon mutations are currently limited. In this paper, we describe the case of a patient bearing uncommon compound mutations in exon 20, who experienced a near-complete response to third-line Osimertinib, with metabolic complete response of pulmonary, nodal and ostheolytic lesions. This radiological assessment corresponded to an ECOG PS improvement (from three to one) and a substantial clinical benefit for the patients.

Article Synopsis
  • Prior to 2021, there was no available data to help choose between BRAF/MEK inhibitors and PD-1/CTLA-4 blockade for treating BRAFV600-mutant melanoma, leading to the SECOMBIT trial to study these options.
  • The trial assessed three treatment sequences: immunotherapy or targeted therapy first, or a combination approach, with the goal of evaluating overall survival.
  • Results indicated that immunotherapy followed by targeted therapy led to better long-term survival, and biomarker analyses suggested that specific genetic mutations may indicate improved outcomes, paving the way for future research on treatment predictions.

Introduction: The CheckMate 238 randomised study demonstrated the relevant benefit in terms of recurrence-free survival (RFS) of nivolumab versus ipilimumab in resected stage IIIB-C or IV melanoma patients with a tolerable safety profile.

Materials And Methods: From November 2018 to June 2019, 611 patients with stage III and IV resected melanoma were enroled to receive nivolumab as part of an Italian Expanded Access Programme (EAP). According to stages, 77% were stage III while 141 (23%) were stage IV with no evidence of disease (NED).

Background: Brain metastases (BM) and lactate dehydrogenase (LDH) levels above the upper limit of normal (ULN) are associated with poor prognosis in patients with melanoma. Although treatment with the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib have demonstrated long-term clinical benefit in patients with melanoma, data on their efficacy in patients with BM are limited.

Methods: DESCRIBE Italy is an observational, retrospective, real-world study evaluating dabrafenib plus trametinib in 499 patients with -mutant stage III unresectable or stage IV melanoma from various sites across Italy.

Article Synopsis
  • - The CheckMate 401 study aimed to evaluate the safety and effectiveness of combining nivolumab and ipilimumab, followed by nivolumab alone, in patients with advanced melanoma who historically have had poor outcomes.
  • - A total of 533 treatment-naive patients with unresectable stage III-IV melanoma were analyzed, revealing incidences of severe adverse events and varying overall survival rates across different patient subgroups.
  • - Results suggested the treatment was generally tolerable, with a 24-month overall survival rate of 63%, but efficacy was notably lower in patients with poorer performance status and specific melanoma subtypes, indicating a need for new treatment strategies.

Background: Following the increased survival of patients with metastatic melanoma thanks to immunotherapy and targeted therapy, neoadjuvant approaches are being investigated to address the unmet needs of unresponsive and intolerant patients. We aim to investigate the efficacy of neoadjuvant plus adjuvant combined or sequenced vemurafenib, cobimetinib and atezolizumab in patients with high-risk, resectable -mutated and wild-type melanoma.

Methods: The study is a phase II, open-label, randomized non-comparative trial in patients with stage IIIB/C/D surgically resectable, -mutated and wild-type melanoma, with three possible treatments: (1) vemurafenib 960 mg twice daily from day 1 to 42; (2) vemurafenib 720 mg twice daily from day 1 to 42; (3) cobimetinib 60 mg once daily from day 1 to 21 and from day 29 to 42; and (4) atezolizumab 840 mg for two cycles (day 22 and day 43).

Malignant pleural mesothelioma (MPM) is a rare, aggressive cancer of the pleural surface associated with asbestos exposure. The median survival of MPM patients is a mere 8-14 months, and there are few biomarkers and no cure available. It is hoped that, eventually, the incidence of MPM will drop and remain low and constant, given that most nations have banned the use of asbestos, but in the meantime, the incidence in Europe is still growing.
