Differences in survival according to the pTERT mutation subtypes (-124C > T, -146C > T, and tandem -138_139CC > TT) have been observed. The present study aimed to describe the clinical as the histopathological and molecular cutaneous melanoma features according to the presence of the three most prevalent pTERT mutation subtypes (-124C > T, -146C > T, and tandem -138_139CC > TT). A retrospective cross-sectional study including 684 patients was designed, and a Partial Least-Squares Discriminant Analysis (PLS-DA) was performed. After the PSL-DA, it was observed that the tandem -138_139CC > TT subtype differs from the other subtypes. The model demonstrated that the -124C > T and the -138_139 CC > TT subtypes were associated with fast-growing melanomas (OR 0.5, CI 0.29-0.86, p = .012) and with Breslow >2 mm (OR 0.6, CI 0.37-0.97, p = .037), compared to the -146C > T mutation. Finally, the -124C > T appeared to be more associated with the presence of TILs (non-brisk) than the -146C > T (OR 0.6, CI 0.40-1.01, p = .05). These findings confirmed that the -124C > T and the tandem -138_139 CC > TT subtypes are both highly associated with the presence of features of aggressiveness; however, only the -124C > T was highly associated with TILs. This difference could explain the worse survival rate associated with the tandem -138_139CC > TT mutations.

PURPOSE: In phase III CheckMate 238, adjuvant nivolumab significantly improved recurrence-free survival compared with ipilimumab in patients with resected stage IIIB-C/IV melanoma without a significant difference in overall survival (OS). Here, we investigate progression-free survival (PFS) and OS after postrecurrence systemic therapy. PATIENTS AND METHODS: Patients 15 years or older with resected stage IIIB-C/IV melanoma were stratified by stage and tumor PD-L1 status and randomly assigned to receive nivolumab 3 mg/kg every 2 weeks, or ipilimumab 10 mg/kg every 3 weeks for four doses and then every 12 weeks for 1 year or until disease recurrence, unacceptable toxicity, or withdrawal of consent. Patients with recurrence in each group were assessed for PFS and OS from subsequent systemic therapy (SST) initiation per recurrence timing (≤12 months [early] v >12 months [late] from initial therapy). RESULTS: Recurrences occurred in 198 (44%) of 453 nivolumab-treated patients (122 early, 76 late) and 232 (51%) of 453 ipilimumab-treated patients (160 early, 72 late). Median PFS on next-line systemic therapy for nivolumab-treated patients recurring early versus late was 4.7 versus 12.4 months (24-month rates, 16% v 31%); median OS was 19.8 versus 42.8 months (24-month rates: 37% v 73%). In response to subsequent therapy, patients on nivolumab with late versus early recurrence were more likely to benefit from anti-PD-1 monotherapy. Nivolumab-treated patients with either an early or late recurrence benefitted from an ipilimumab-based therapy or targeted therapy, each with similar OS. CONCLUSION: Postrecurrence survival was longer for patients who recurred >12 months. Patients on nivolumab who recurred early benefitted from SST but had better survival with ipilimumab-based regimens or targeted therapy compared with anti-PD-1 monotherapy.

BACKGROUND: Treatment with encorafenib plus binimetinib and encorafenib monotherapy is associated with improved progression-free survival (PFS) and overall survival (OS) compared with vemurafenib in patients with BRAF V600E/K-mutant metastatic melanoma. We report results from the 7-year analysis of COLUMBUS part 1 (NCT01909453) at 99.7 months (median duration between randomization and data cutoff). METHODS: 577 patients with locally advanced unresectable or metastatic BRAF V600E/K-mutant melanoma who were treatment-naive or progressed after first-line immunotherapy were randomized 1:1:1 to encorafenib 450 mg once daily (QD) plus binimetinib 45 mg twice daily (BID) (n = 192), vemurafenib 960 mg BID (n = 191), or encorafenib monotherapy 300 mg QD (n = 194). No prior BRAF/MEK inhibitor was allowed. RESULTS: Seven-year PFS and OS rates (95 % CI) were 21.2 % (14.7-28.4 %) and 27.4 % (21.2-33.9%) in the encorafenib plus binimetinib arm and 6.4 % (2.1-14.0 %) and 18.2 % (12.8-24.3 %) in the vemurafenib arm, respectively. Median melanoma-specific survival (95 % CI) was 36.8 months (27.7-51.5 months) in the encorafenib plus binimetinib arm and 19.3 months (14.8-25.9 months) in the vemurafenib arm. Thirty-four long-term responders (complete/partial response ongoing at 7 years) were identified across arms. CONCLUSIONS: This is the longest follow-up from a phase III trial of BRAF/MEK inhibitor combination in BRAF V600E/K-mutant metastatic melanoma. Safety results were consistent with the known tolerability profile of encorafenib plus binimetinib. Results support the long-term efficacy and known safety of encorafenib plus binimetinib in this population and provide new insights on long-term responders.

Uveální melanom je svým výskytem vzácnou, i když současně nejčastější nitrooční malignitou dospělých. Má velmi vysoké riziko metastazování a jeho biologické charakteristiky s obecně nízkou mutační náloží limitují využití imunoterapie s inhibitory kontrolních bodů. Zásadní molekulou v léčbě se tedy jeví tebentafusp, i když jen pro vybranou podskupinu pacientů s fenotypem HLA-A*02:01. Léčba tebentafuspem je zatížena vysokým výskytem reakce z uvolnění cytokinů (cytokine release syndrom) a kožního exantému a v úvodních infuzních aplikacích léčiva s doporučeným vzestupným dávkováním je potřeba hospitalizace a pečlivá monitorace pacienta.

Uveal melanoma is a rare, however at the same time it is the most common intraocular malignancy in adults. It has a very high risk of metastatic disease and its biological characteristics with a generally low mutational burden limit the use of immunotherapy with checkpoint inhibitors. Therefore, tebentafusp appears to be the essential molecule in the treatment, although only for a selected subgroup of patients with the phenotype HLA-A*02:01. The application of tebetafusp is accompanied by a high incidence of cytokine release syndrome and skin exanthema. In the initial infusion administration with an increasing dosing hospitalization and careful monitoring of the patient is required.

Mucosal malignant melanoma (MMM) is a rare and aggressive tumor. Despite effective local therapies, tumor recurrence and metastasis remain frequent. The genetics of MMM remain incompletely understood. This study is aimed to identify actionable genetic alterations by next-generation sequencing. Fifteen MMM samples were analyzed by next-generation and Sanger sequencing. Gene copy number alterations were analyzed by MLPA. Mutation status was correlated with pERK, pAKT, and Ki-67 expression and follow-up data. Inactivating mutations and intragenic deletions in neurofibromatosis type-1 (NF1) were identified in 3 and 2 cases, respectively, (in total 5/15, 33%) and activating mutations in NRAS and KRAS (3/15, 20%) cases. Other mutated genes included CDKN2A, APC, ATM, MITF, FGFR1, and FGFR2. BRAF and KIT mutations were not observed. Cases with NF1 alterations tended to have worse overall survival. The mutational status was not associated with pERK, pAKT, or Ki-67 immunostaining. MMM carries frequent gene mutations activating the MAPK pathway, similar to cutaneous melanoma. In contrast, NF1 is the most frequently affected gene. Intragenic NF1 deletions have not been described before and may go undetected by sequencing studies. This finding is clinically relevant as NF1-mutated melanomas have worse survival and could benefit from therapy with immune checkpoint and MEK inhibitors.

BACKGROUND: Favorable survival in malignant cutaneous melanoma (melanoma) has increased the likelihood of second primary cancer (SPC). We assess the influence of patient characteristics at diagnosis of first melanoma and the type of SPC (second melanoma and other SPC) on overall survival. METHODS: We used the Swedish Cancer Registry data to assess overall survival in melanoma for the period 1990 to 2015. Kaplan-Meier curves were plotted and hazard ratios (HRs) were estimated with Cox regression models by considering SPC diagnosis as a time-dependent variable. RESULTS: A total of 46,726 patients were diagnosed with melanoma, and 15.3% of them developed SPC, among which, two thirds were other SPCs. Second melanomas were diagnosed early (31% during the first year) compared to non-melanoma SPCs (9.5%). Survival for women with second melanoma or other SPC (56 and 21% alive after 25 years of follow-up, respectively) exceeded the male rates (21 and 10%, respectively) but all these figures were lower than for females (60% alive) or males (48%) without SPC. Time dependent analysis showed vastly increased HRs for cancer types that are fatal also as first cancers, but SPC-specific HRs remained relatively uniform, irrespective of SPC diagnosed soon or late after first melanoma. In early-onset melanoma, SPC diagnosis after 10 years may not negatively influence overall survival. CONCLUSIONS: As the overall survival of patients with many types of SPCs is unfavorable, advice about health lifestyle should benefit smoking patients and early detection methods may be recommended for SPCs of the breast, prostate and colorectum.

The ability to adapt to environmental stress, including therapeutic insult, contributes to tumor evolution and drug resistance. In suboptimal conditions, the integrated stress response (ISR) promotes survival by dampening cytosolic translation. We show that ISR-dependent survival also relies on a concomitant up-regulation of mitochondrial protein synthesis, a vulnerability that can be exploited using mitoribosome-targeting antibiotics. Accordingly, such agents sensitized to MAPK inhibition, thus preventing the development of resistance in BRAFV600E melanoma models. Additionally, this treatment compromised the growth of melanomas that exhibited elevated ISR activity and resistance to both immunotherapy and targeted therapy. In keeping with this, pharmacological inactivation of ISR, or silencing of ATF4, rescued the antitumoral response to the tetracyclines. Moreover, a melanoma patient exposed to doxycycline experienced complete and long-lasting response of a treatment-resistant lesion. Our study indicates that the repurposing of mitoribosome-targeting antibiotics offers a rational salvage strategy for targeted therapy in BRAF mutant melanoma and a therapeutic option for NRAS-driven and immunotherapy-resistant tumors.

BACKGROUND: In COLUMBUS, treatment with encorafenib plus binimetinib in patients with advanced BRAF-mutant melanoma showed improved progression-free and overall survival with favourable tolerability compared to vemurafenib treatment. Here, results on health-related quality of life (HRQoL) are presented. METHODS: COLUMBUS was a two-part, open-label, randomised, phase III study in patients with BRAF-mutant melanoma. In PART-I, 577 patients were randomised (1:1:1) to encorafenib plus binimetinib, encorafenib or vemurafenib. The primary objective was to assess progression-free survival. As a secondary objective, HRQoL was assessed by the EQ-5D, the EORTC QLQ-C30 and the FACT-M questionnaires. Furthermore, time to definitive 10% deterioration was estimated with a Kaplan-Meier analysis and differences in mean scores between groups were calculated with a mixed-effect model for repeated measures. Hospitalisation rate and the impact of hospitalisation on HRQoL were also assessed. RESULTS: Patients receiving the combination treatment showed improvement of their FACT-M and EORTC QLQ-C30 global health status scores, compared to those receiving vemurafenib (post-baseline score differences: 3.03 [p < 0.0001] for FACT M and 5.28 [p = 0.0042] for EORTC QLQ-C30), indicative of a meaningful change in patient's status. Furthermore, a delay in the deterioration of QoL was observed in non-hospitalised patients compared to hospitalised patients (hazard ratio [95% CI]: 1.16 [0.80; 1.68] for EORTC QLQ-C30 and 1.27 [0.81; 1.99] for FACT-M) and a risk reduction of 10% deterioration, favoured the combination in both groups. CONCLUSION: The improved efficacy of encorafenib plus binimetinib compared to vemurafenib, translates into a positive impact on the perceived health status as assessed by the HRQoL questionnaires. The study is registered with ClinicalTrials.gov, number NCT01909453 and EudraCT number 2013-001176-38.
