There were 11 ovarian cancer (<em>n</em> = 4348), 8 prostate cancer (<em>n</em> = 3872), 9 breast cancer (<em>n</em> = 4448), 4 NSCLC (<em>n</em> = 1063), and 3 SCLC (<em>n</em> = 583) studies, and 1 study each for pancreatic cancer (<em>n</em> = 50), glioblastoma (<em>n</em> = 123), and gastric (<em>n</em> = 521) cancer. The incidence of any-grade VTEs with PARPi was observed to be 2.4%, compared with 1.6% in controls, suggesting a possible increase in risk [odds ratio (OR) 1.37, 95% confidence interval (CI) 1.00-1.88, <em>P</em> = 0.050]. This association appeared to be more pronounced in patients with prostate cancer (OR 1.98, 95% CI 1.06-3.70, <em>P</em> = 0.030) and pancreatic cancer (OR 7.22, 95% CI 1.40-37.25, <em>P</em> = 0.020).</div></div><div><h3>Conclusions</h3><div>While our findings indicate a possible association between PARPi and VTE risk in certain cancer types, this risk appears to be influenced by factors such as cancer subtype and treatment combinations. The overall contribution of PARPi monotherapy to VTE risk may be limited, and the results should be interpreted with caution due to study heterogeneity, wide CIs, and the absence of patient-level data.</div></div>","PeriodicalId":11877,"journal":{"name":"ESMO Open","volume":"10 10","pages":"Article 105811"},"PeriodicalIF":8.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145198689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Antibody–drug conjugates (ADCs) represent an emerging therapeutic option in oncology. Their efficacy is dependent on the expression of the ADC target on tumor cells. Very few data are available on ADC target expression in STSs.</div></div><div><h3>Materials and methods</h3><div>We analyzed the mRNA expression of 62 targets and 60 genes potentially involved in resistance/response to ADC in 1664 clinical primary tumors, including 476 liposarcomas (LPSs) 341 leiomyosarcomas, 330 undifferentiated pleomorphic sarcomas, 286 gastrointestinal stromal tumors, 126 synovial sarcomas, and 105 myxofibrosarcomas. Tumor expression in each type was compared with expression in 7414 normal tissue samples. To confirm the results at the protein level, we applied immunohistochemistry (IHC) to four ADC targets in another series of STS samples.</div></div><div><h3>Results</h3><div>Expression profiles of ADC targets were heterogeneous across and within all STS types. All types expressed multiple ADC targets. An overexpression rate of at least 25% of samples in at least one type was observed for 41 targets. The high target overexpression rate in some STS types suggested numerous new therapeutic opportunities not currently studied in clinical trials, such as PTK7 overexpressed in 81% of LPSs. In addition, co-expression of ADC-target pairs and of targets with signatures of vulnerability to immune checkpoint inhibitors, poly (ADP-ribose) polymerase (PARP) inhibitors, and cyclin-dependent kinase (CDK)4/6 inhibitors was evidenced in the different pathological types, suggesting opportunities for testing ADC-based combinations. Finally, we showed heterogeneous expression profiles of potential ADC resistance/response genes between and within STS types. IHC confirmed the mRNA results for the four tested targets.</div></div><div><h3>Conclusion</h3><div>STSs express multiple target genes relevant for ADC treatment and expression varies between and within the pathological types. This comprehensive ADC target landscape, based on the largest molecular epidemiology study in STS, should help clinicians and drug developers for further evaluation of ADCs across STS types.</div></div>","PeriodicalId":11877,"journal":{"name":"ESMO Open","volume":"10 10","pages":"Article 105837"},"PeriodicalIF":8.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145227276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
