Many of these syndromes are associated with specific phenotypic features and are discussed in the related paper from the AACR Pediatric Cancer Working Group. Guidelines for surveillance in this population were published in 2017 but since then several studies have identified new genes with recurrent pathogenic variants associated with increased risk for Wilms tumor development. In general, variants in these genes are less likely to be associated with other phenotypic features. Recently, members of the AACR Pediatric Cancer Working Group met to update surveillance guidelines for patients with a predisposition to Wilms tumors with a review of recently published evidence and risk estimates. Risk estimates for Wilms tumor for the more recently described genes are discussed here along with suggested surveillance guidelines for these populations. Several other emerging clinical scenarios associated with Wilms tumor predisposition are also discussed including patients with family histories of Wilms tumor and no identified causative gene, patients with bilateral tumors, and patients with somatic mosaicism for chromosome 11p15.5 alterations. This perspective serves to update pediatric oncologists, geneticists, radiologists, counselors and other healthcare professionals on emerging evidence and harmonize updated surveillance recommendations in the North American and Australian context for patients with emerging forms of Wilms tumor predisposition.</p>","PeriodicalId":10279,"journal":{"name":"Clinical Cancer Research","volume":" ","pages":""},"PeriodicalIF":10.0,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142496192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to quantify their prognostic impact after prostate cancer diagnosis. Methods: Men with prostate cancer, predominantly of European ancestry, were included from four cohorts with long-term follow-up. Pathogenic or likely pathogenic germline variants in 26 DNA repair genes were assessed in relation to metastasis-free survival in high-risk, localized prostate cancer and to overall survival in metastatic castration-sensitive prostate cancer (mCSPC) and metastatic castration-resistant prostate cancer (mCRPC). Results: Among 3,525 patients initially diagnosed with non-metastatic prostate cancer, 2,594 had high-risk localized prostate cancer, 429 mCSPC, and 502 mCRPC at inclusion. BRCA2 variant carriers did not have worse metastasis-free survival in high-risk localized prostate cancer (hazard ratio [HR] 1.01, 95% confidence interval [CI] 0.69, 1.46) or overall survival in mCSPC (HR 0.46, 95% CI 0.14, 1.45) or mCRPC (HR 0.60, 95% CI 0.31, 1.17) compared to non-carriers of DNA repair variants. Among 868 additional patients with de novo metastatic (M1) prostate cancer, BRCA2 variant carriers tended to have worse overall survival (HR 1.59, 95% CI 1.01, 2.51). BRCA2 prognostic associations were not explained by radiation, PARP inhibitor, or platinum therapy. Results for other genes were limited in precision because variants were less common. Conclusions: Among patients with high-risk or metastatic prostate cancer who were initially diagnosed with and treated for non-metastatic tumors, germline DNA repair variants in BRCA2 do not confer a substantially worse prognosis.","PeriodicalId":10279,"journal":{"name":"Clinical Cancer Research","volume":"14 1","pages":""},"PeriodicalIF":11.5,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142489810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combination of angiogenesis inhibitors with immune checkpoint inhibitors (ICIs) has shown efficacy against many types of cancers, including non-small cell lung cancer (NSCLC). We investigated the feasibility of neoadjuvant therapy with pembrolizumab and ramucirumab, a vascular endothelial growth factor (VEGF) receptor-2 antagonist for patients with PD-L1-positive NSCLC and its influence on the tumor microenvironment (TME). Patients and Methods: Patients with pathologically proven NSCLC with PD-L1-positive, clinical stage IB-IIIA were eligible. Patients received two cycles of pembrolizumab (200 mg/body) and ramucirumab (10 mg/kg) every three weeks. Surgery was scheduled 4 to 8 weeks after the last dose. The primary endpoint was the major pathologic response (MPR) rate by a blinded independent pathology review. The sample size was 24 patients. Exploratory endpoints were evaluated to elucidate the effects of neoadjuvant therapy on TME. Results: The 24 eligible patients were enrolled between July 2019 and April 2022. The MPR rate was 50.0% (90% confidence interval, 31.9-68.1%). Six patients showed pathological complete response. Grade 3 adverse events (AEs) occurred in 9 patients (37.5%), including 3 immune-related AEs (acute tubulointerstitial nephritis in 2 cases and polymyalgia rheumatica in one). There were no grade 4 or 5 AEs. The transcriptome and multiplexed immunohistochemistry results suggested that tumors with greater CD8+ T-cell infiltration and higher expression of effector molecules at the baseline could show better sensitivity to treatment. Conclusions:This new neoadjuvant combination of pembrolizumab plus ramucirumab was feasible and anti-VEGF agents may enhance the effects of ICIs.","PeriodicalId":10279,"journal":{"name":"Clinical Cancer Research","volume":"7 1","pages":""},"PeriodicalIF":11.5,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142490293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to explore the efficacy and safety of anlotinib (a tyrosine-kinase inhibitor) and TQB2450 (a PD-L1 inhibitor) in ASPS patients. Methods: This single-arm, phase 2 study evaluated the efficacy of TQB2450, an anti-programmed death ligand 1 (PD-L1) agent, combined with anlotinib, a TKI, in adults with advanced ASPS. TQB2450 was given intravenously (1,200 mg) on day 1, and anlotinib (12 mg/day) was taken orally from day 1 to day 14 every 3 weeks. The primary endpoint was overall response rate, with secondary endpoints including duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Lymphocyte infiltration and tertiary lymphoid structure (TLS) were also analyzed as potential prognostic biomarkers. Results: The study enrolled 29 patients, with 28 evaluable (one withdrew due to acute pancreatitis). An objective response was achieved in 82.1% of patients, including 4 complete and 19 partial responses. The median time to response was 2.8 months, and the DOR was not reached, with an estimated median PFS of 35.2 months. Grade 3-4 treatment-related adverse events occurred in 44.8% of patients, with no study-related deaths. Responders had a higher proportion of TLS area, density, and CD20-positive immune cells.

This translational study was designed to test the ATR inhibitor berzosertib in patients with advanced solid tumors carrying alterations in ATRX, ATM, genes conferring replication stress (RS), or SDH. Methods: Patients were recruited to 4 cohorts: T1: ATRX-mutant leiomyosarcoma; T2: ATM-mutant solid tumors; T3: solid tumors with mutations in RS-associated genes; and T4: SDH-deficient GIST. Patients were treated with berzosertib 240 mg/m2 IV twice per week. Pre and on-treatment biopsies were obtained in cohorts T1-T3. Results: Patients with SDH-mutant GIST had the longest median progression-free survival (PFS) (229 days) with stable disease as the best response. Patients in the other cohorts experienced progressive disease within 4 months. There was no significant difference in PFS comparing outcomes in patients with/without mutations in ATM or RS genes. Decreased pS345-CHK1 in on-treatment biopsies indicated target engagement by berzosertib and were accompanied by substantial increases in levels of DNA damage (g-H2AX) and RS (pKAP1) markers in a subset of patients. However, these biomarker changes did not translate to clinical benefit. In contrast, in cohorts T1-T3, increased expression of SFLN11 on treatment correlated with clinical benefit (HR = 0.045; 95%CI 0.005-0.400). Conclusions: Across cohorts, only SDH-mutant GIST patients experienced prolonged disease control. Despite evidence of target engagement, patients enrolled to all other cohorts had short PFS, suggesting rapid adaptation to ATR inhibitor monotherapy.

Patients and methods: This was a first-in-human phase I study of BAY 2666605 (NCT04809805), an oral, potent first-in-class PDE3A-SLFN12 complex inducer, with reduced PDE3A inhibition. Adults with advanced solid tumors that co-express SLFN12 and PDE3A received BAY 2666605 at escalating doses starting at 5 mg once daily in 28-day cycles. Forty-seven patients were pre-screened for SLFN12 and PDE3A overexpression, and 5 biomarker-positive patients received ≥ 1 BAY 2666605 dose. Results: The most common adverse event was grade 3-4 thrombocytopenia in 3 of the 5 patients treated. The long half-life (&amp;gt; 360 hours) and associated accumulation of BAY 2666605 led to the selection of an alternative schedule consisting of a loading dose with QD maintenance dose. The maximum tolerated dose was not established as the highest doses of both schedules were intolerable. No objective responses were observed. Due to the high expression of PDE3A in platelets compared to tumor tissues, the ex vivo dose-dependent inhibitory effect of BAY 2666605 on megakaryocytes, and the pharmacokinetic profile of the compound, alternative schedules were not predicted to ameliorate the mechanism-based thrombocytopenia. Conclusions: Despite the decreased PDE3A enzymatic inhibition profile of BAY 2666605, the occurrence of thrombocytopenia in treated patients, an on-target effect of the compound, precluded the achievement of a therapeutic window, consequently leading to trial termination.","PeriodicalId":10279,"journal":{"name":"Clinical Cancer Research","volume":"34 1","pages":""},"PeriodicalIF":11.5,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental Design: In this study, patients with advanced NSCLC and a positive PET scan within 42 days of first line treatment were enrolled in 11 institutions across 4 countries. Total MTV (tMTV) was analyzed, with a 42% SUVmax threshold. Survival was analyzed according to high tMTV (≥ median). Plasma proteomic profile, whole exome, transcriptome and other analysis were performed on monocentric cohorts to explore its biological correlates. Results: Of the 518 patients included, 167 received ICBs, 257 had chemotherapy plus ICBs, and 94 had chemotherapy. Median tMTV was 99 cm3. Median overall survival (OS) for patients with high tMTV treated with ICBs was 11.4 months vs 29.6 months (P&amp;lt;0.0012) for those with low tMTV. In patients receiving chemotherapy-ICB tMTV did not correlate with OS (P=0.099). In patients with PD-L1≥1% and high tMTV, chemotherapy-ICB combination was associated with longer OS compared with ICBs alone (20 vs 11.4 months,p=0.026), while no survival differences observed in low tMTV group. High tMTV correlated (and its detrimental effect seems to be driven by) a specific proteomic profile and increase in genomic instability.
