However, the pathogenesis of pyrexia and factors to identify patients at higher risk of developing pyrexia remain unknown. The ELDERLYMEL study was a multicenter, noninterventional, retrospective, real-world study comparing the effectiveness and safety of dabrafenib plus trametinib between elderly (≥75 years, n = 29) and younger (<75 years, n = 130) advanced melanoma BRAF V600-mutated patients in Spain. Surprisingly, pyrexia was significantly less frequent in elderly patients (13.8%) than in younger (42.3%). The post hoc analysis presented here aimed to investigate the relationship between age and pyrexia, applying logistic regression models. Patients <75 years had 4.59 more possibilities to develop pyrexia than elderly patients. The possibility of developing pyrexia increased by 1.03 as age decreased by 1 year. Receiver operating characteristics curves identified 61.5 years as the optimal cutoff value to predict the onset of pyrexia. The age-adjusted regression model revealed that patients <61.5 years had 2.53 more possibilities to develop pyrexia than those ≥61.5. This study demonstrates, for the first time, that age significantly influences the development of pyrexia in patients with BRAF V600-mutated advanced melanoma receiving dabrafenib plus trametinib. Age should be considered in the management and follow-up of these patients but should not limit treatment decisions. These findings provide important insights for clinical practice and contribute to a better understanding of pyrexia in elderly patients. The constructed nomogram based on age could serve as a useful tool for estimating the risk of pyrexia in patients receiving this treatment.</p>","PeriodicalId":18550,"journal":{"name":"Melanoma Research","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143365246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a targeted sequencing panel encompassing 330 amplicons, we targeted hotspot regions in 41 cancer genes and 154 single nucleotide polymorphisms. The clonal relation between primary and matched metastasis tumors was evaluated by comparing the mutational status and the copy number variations profile in 15 patients with primarily thin melanomas and distant metastases, or with a long latency between the primary melanoma and distant metastasis. Our findings revealed that only about 50% of the analyzed matched primaries and metastases were clonally or likely clonally related, while the remaining sets were either not clonally related or difficult to determine with certainty the clonal relatedness. The findings of our study illustrate the intricate clonal relationships between primary melanoma and metastasis and raise doubts if the metastatic potential is overestimated in the primary tumors.

The aim of this study is to assess the impact of continuing ICI after progression of the disease on the overall survival (OS) in a cohort of final-line metastatic melanoma patients. Clinical data from 120 patients with metastatic melanoma were collected via Melbase, a French multicentric biobank, prospectively enrolling unresectable melanoma. Two groups were defined: patients continuing final-line ICI at progression (treated) and patients stopping ICI at progression (controls). The primary end-point is the OS from progression. Propensity score weighting was used to correct for indication bias. From the 120 patients, 72 (60%) continued ICI. Median OS from progression was 4.2 months [95% confidence interval (CI) 2.6-6.27] in the treated group and median OS was 1.3 months (95% CI 0.95-1.74) in the control group ( P  < 0.0001).
