Advanced melanoma (AM), categorized as stage III and IV, presents considerable treatment challenges due to its complex mutational landscape. Traditional treatment options have included checkpoint inhibitors and BRAF inhibitors, with pembrolizumab emerging as a promising agent. Approved by the FDA and EMA for various stages of melanoma, pembrolizumab is a humanized monoclonal antibody that blocks the PD-1/PD-L1 interaction, thereby enhancing immune system-mediated tumor eradication. This abstract discusses a recent phase 2 clinical trial evaluating the efficacy of neoadjuvant (presurgery) versus adjuvant (postsurgery) pembrolizumab treatment in resectable stage III or IV melanoma. The study, involving 313 patients across 90 US hospitals, found that neoadjuvant-adjuvant pembrolizumab significantly improved event-free survival (72%) compared to adjuvant-only treatment (49%) after 2 years. Treatment-related adverse events were consistent with known profiles, including fatigue, nausea, and diarrhea, without new severe adverse effects. No increase in surgery-related complications was observed with neoadjuvant treatment. These findings suggest that neoadjuvant pembrolizumab offers substantial benefits over adjuvant-only treatment, although further research is warranted. Future studies should focus on larger cohorts, diverse demographics, and extended follow-up to validate these results and potentially integrate neoadjuvant pembrolizumab into standard treatment protocols for advanced melanoma.</p>","PeriodicalId":21750,"journal":{"name":"Seminars in oncology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142648747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By interrogating a large contemporary cohort comprised of 10,233 patients with a diagnosis of cancer across all tumor stages and TMB levels, this study revealed significantly improved overall survival (OS) following ICI therapy (P < .0001) in patients with a combination of ≥10 mut/Mb and stage IV disease. In contrast, ICI therapy is associated with markedly worse OS in patients with low TMB levels <10 mut/Mb and stages I, II, and III cancer. These findings highlight the critical interplay between TMB, tumor stage, and ICI treatment outcomes, underscoring the importance of integrating clinical and genetic characteristics in weighing the risk-benefit balance of ICI therapy.

This may require enrolling patients with less-severe or early-stage disease to enable long-term follow-up with effective clinical surveillance.

Median duration of ICI therapy was 155 days. 223 Veterans received ICI monotherapy, with only 17(8%) having a reduction in PSA (median decline = 43%). 12 (5%) had PSA declines &gt;30% (PSA30) which included 6 (3%) who had PSA reductions greater than 50% (PSA50). Median <strong><em>g</em></strong>-rates for ICI plus abiraterone (n = 20) or enzalutamide (n = 31) were 0.000689/d<sup>−1</sup> and 0.002819/d<sup>−1</sup>, respectively, and were statistically insignificant compared to <strong><em>g</em></strong>-rates of matched cohorts receiving abiraterone (<strong><em>g</em></strong> = 0.000925/d<sup>−1</sup>, <em>P</em> = 0.73) or enzalutamide (<strong><em>g</em></strong> = 0.001929/d<sup>−1</sup>, <em>P</em><span> = 0.58) alone. Our data align with clinical trial data in PC, demonstrating limited benefit from ICI monotherapy and predicting no survival benefit from simultaneous abiraterone or enzalutamide with an ICI using </span><strong><em>g</em></strong>-rate.</p></div>","PeriodicalId":21750,"journal":{"name":"Seminars in oncology","volume":"51 3","pages":"Pages 59-68"},"PeriodicalIF":3.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141029034","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
