However, there remains a gap in determining their applicability and risk-benefit profile, across the broad spectrum of patients whose tumors harbor varying TMB levels across distinct tumor stages. 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 (<em>P</em> &lt; .0001) in patients with a combination of <span><math><mo>≥</mo></math></span>10 mut/Mb and stage IV disease. In contrast, ICI therapy is associated with markedly worse OS in patients with low TMB levels &lt;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. Although maximizing therapeutic benefits is crucial, it is equally important to identify and manage potential risks that may not be immediately apparent. This may require enrolling patients with less-severe or early-stage disease to enable long-term follow‐up with effective clinical surveillance. By comprehensively evaluating the added benefit of improved treatment efficacy and the potential risk of adverse treatment outcome, a risk-benefit profile can optimize immunotherapy regimens, with profound implications for clinical decision-making and regulatory approvals of ICI.</div></div>","PeriodicalId":21750,"journal":{"name":"Seminars in oncology","volume":"51 5","pages":"Pages 142-148"},"PeriodicalIF":3.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626806","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}

Fifty-two BC survivors answered the study's survey. A total of three (6%) cases of second primary malignancies were self-reported. Cervical cancer screening was performed within the past 3 years among 37/50 (74%) eligible participants. Only 7/24 (29%) eligible participants underwent colorectal cancer screening within the last 10 years, including six colonoscopies and 1 occult blood test. No participant had an indication for lung cancer screening. The primary reason for noncompliance with both cervical and colorectal cancer screening was lack of physician's recommendation, accounting for 79% and 88% of cases, respectively. Nearly all participants (98%) affirmed that BC survivors should undergo screening for other types of cancer. Most (96%) stated that, if recommended by a physician, they would agree to undergo screening for other neoplasms. Even though most BC survivors acknowledged its importance, screening particularly for colorectal cancer exhibited suboptimal rates. Oncologists could play a crucial role in increasing cancer screening uptake by reminding patients of their corresponding recommendations to detect other types of cancer.</div></div>","PeriodicalId":21750,"journal":{"name":"Seminars in oncology","volume":"51 5","pages":"Pages 156-160"},"PeriodicalIF":3.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626829","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}
