The purpose ot this study was to assess the effectiveness of an educational video compared to in-person genetic counseling for cancer genetic testing candidates. Genetic cancer risk assessment is essential for tailoring oncological treatment, identifying individuals at higher risk of cancer, implementing risk-reduction strategies, and enabling family cascade testing. Pretest genetic counseling facilitates an individual's informed decision making and reduces anxiety. However, the availability of genetics specialists is limited in constrained resource settings.

Acalabrutinib is a Bruton tyrosine kinase inhibitor approved for the treatment of chronic lymphocytic leukemia. We present results from ELEVATE-TN after a median follow-up of 74.5 months. Overall, 535 patients were randomized (acalabrutinib-obinutuzumab, n = 179; acalabrutinib, n = 179; chlorambucil-obinutuzumab, n = 177). Median age was 70 years, 63.0% had unmutated immunoglobulin heavy chain variable region gene (uIGHV), 13.6% had del(17p) and/or mutated TP53, and 17% had complex karyotype (CK; ≥3 chromosomal abnormalities). Median progression-free survival (PFS) was not reached (NR) for acalabrutinib-obinutuzumab and acalabrutinib vs 27.8 months for chlorambucil-obinutuzumab (both P < .0001); estimated 72-month overall PFS rates were 78.0%, 61.5%, and 17.2%, respectively. Acalabrutinib-obinutuzumab resulted in improved PFS vs acalabrutinib monotherapy (hazard ratio [HR], 0.58; P = .0229). Patients with uIGHV, del(17p) and/or mutated TP53, or CK had significantly improved PFS with acalabrutinib ± obinutuzumab vs chlorambucil-obinutuzumab (P < .0001, P ≤ .0009, and P < .0001 for both acalabrutinib-containing arms, respectively). Median overall survival (OS) was NR for all treatments, with significantly longer OS for acalabrutinib-obinutuzumab than chlorambucil-obinutuzumab (HR, 0.62; P = .0349). Estimated 72-month OS rates were 83.9%, 75.5%, and 74.7% for acalabrutinib-obinutuzumab, acalabrutinib, and chlorambucil-obinutuzumab, respectively. Adverse events (AEs) occurring after >4 years were mostly grade 1 to 2. Rates of AEs, serious AEs, and events of clinical interest were similar between acalabrutinib-containing arms and consistent with the known safety profiles of acalabrutinib and obinutuzumab. Efficacy and safety of acalabrutinib-containing arms were maintained, with longer PFS in both acalabrutinib arms than chlorambucil-obinutuzumab including in patients with high-risk features. This trial was registered at www.ClinicalTrials.gov as #NCT02475681.

Large genomic programs have contributed to improving drug development in cancer. To assess the potential benefit of using larger gene panels to guide molecular-based treatments, we conducted a multicenter randomized trial in patients with advanced and/or metastatic solid cancer. Molecular alterations were determined using either a panel of 324 cancer-related genes (Foundation OneCDX (F1CDX)) or a limited panel of 87 single-nucleotide/indel genes and genome-wide copy number variations (CTL) and reviewed by a molecular tumor board to identify molecular-based recommended therapies (MBRTs). Using paired data from both panels for each patient, the primary endpoint was the proportion of patients with an MBRT identified. Main secondary endpoints included the number of patients with at least one actionable alteration leading to MBRT identification, the number of patients with and without MBRTs initiated, progression-free survival, best overall response, duration of response and safety. Among the 741 patients screened, 45.7% had quality-checked tumor samples. MBRTs were identified with F1CDX in 175 (51.6%) patients and with CTL in 125 (36.9%) patients, translating to a significant increase of 14.8 percentage points (P < 0.001) with the more comprehensive gene panel versus the more limited panel, meeting the primary endpoint. However, no differences in clinical outcomes were observed in these patients with advanced and/or metastatic cancer in need of treatment beyond standard genomic alterations. These findings illustrate the potential for larger gene panels to increase the number of molecularly matched therapies. Larger studies are needed to assess the clinical benefit of expanded MBRTs.

To evaluate local failure (LF) rates for patients with intermediate-risk rhabdomyosarcoma treated on the Children's Oncology Group ARST1431 clinical trial, the first and largest international, phase 3 randomized study to use FOXO1 fusion status for risk stratification. To improve local control, radiation therapy (RT) dose was increased to 59.4 Gy for patients with tumors >5 cm and residual gross disease at the time of RT.

Oxidative stress-induced DNA damage may impact long-term outcomes in colorectal cancer (CRC) patients. While bioactive compounds in plant foods have been linked to DNA protection, evidence among patients in remission remains limited. The present study aimed to investigate the effect of a one-year personalized intensive dietary intervention on DNA damage in post-surgery, non-metastatic CRC patients. Participants were enrolled 2-9 months after surgery in the ongoing randomized controlled trial, Norwegian dietary guidelines and colorectal cancer survival (CRC-NORDIET). Eligible participants (aged 50-80 years, primary stage I-III CRC) were randomized to either a plant-based dietary intervention targeting oxidative stress and inflammation, or to a control group that received standard dietary advice as a part of routine cancer care. As a secondary analysis, this study included 156 participants (78 in the intervention group and 78 in the control group) from the total 503 patients enrolled in CRC-NORDIET study. DNA damage in peripheral mononuclear blood cells (PBMCs) was assessed using the enzyme-modified comet assay during a 12-month follow-up period. A significant intervention effect on DNA base oxidation from baseline to 12 months was observed (P = 0.04), representing a 32 % reduction in the intervention group compared to the control group. No significant effect on DNA strand breaks was found. In conclusion, adherence to a plant-based dietary pattern may reduce DNA base oxidation in post-surgery CRC patients.

In the phase 3 TALAPRO-2 trial, talazoparib plus enzalutamide significantly improved radiographic progression-free survival compared with placebo plus enzalutamide in men with metastatic castration-resistant prostate cancer harbouring alterations in genes involved in homologous recombination repair (HRR). We aimed to assess patient-reported outcomes in patients with HRR-deficient metastatic castration-resistant prostate cancer in TALAPRO-2.

Patients with metastatic castration-resistant prostate cancer have poor prognoses, underscoring the need for novel therapeutic strategies. First-line talazoparib plus enzalutamide significantly improved radiographic progression-free survival compared with placebo plus enzalutamide in men with metastatic castration-resistant prostate cancer in the phase 3 TALAPRO-2 study. We aimed to evaluate patient-reported outcomes in the all-comers cohort of TALAPRO-2, which included patients with and without alterations in homologous recombination repair (HRR) genes.

Primary tumor sidedness (PTS) with discrimination of left-sided (LC) and right-sided tumors (RC) guides patient selection for targeted first-line therapy in RAS wild-type (RAS-WT) metastatic colorectal cancer (mCRC). This study assessed the hypothesis whether considering PTS with additional clinical parameters better predicts the treatment benefit of targeted first-line treatment.

Although multiple agents targeting PD-1 have been approved as second-line treatment for esophageal squamous cell carcinoma (ESCC), only a fraction of patients derive long-term survival. Hence, reliable predictive biomarkers are urgently needed.

Estimating breast cancer risk involves quantifying genetic and non-genetic factors. This supports health interventions and risk communication to ensure adherence to screening recommendations. This study evaluated the change in risk estimation when incorporating breast density and polygenic risk score (PRS) into the baseline cancer risk assessment and compared the efficacy of 2 risk-assessment delivery models.

In the phase 3 ponatinib-3001 trial (PhALLCON, NCT03589326), ponatinib demonstrated superior efficacy over imatinib with comparable safety in patients with newly diagnosed Philadelphia-positive acute lymphoblastic leukemia (Ph+ ALL). This post hoc analysis evaluated the net benefits of ponatinib using a quality-adjusted time without symptoms of disease or toxicity (Q-TWiST) approach.

There is a need to better understand the molecular features that characterize grade 3 astrocytomas and their significance in predicting clinical outcomes. The aim of this study was to determine the significance of the 2021 World Health Organization (WHO)-defined molecular subgroups, along with MGMT promoter methylation, and other alterations in NRG Oncology/RTOG 9813.

This study was performed to confirm the superiority in overall survival (OS) of EGFR tyrosine kinase inhibitor (TKI gefitinib or osimertinib) monotherapy versus EGFR TKI with intercalation of cisplatin plus pemetrexed as the first-line treatment for patients with advanced non-squamous non-small cell lung cancer (NSqNSCLC) harboring EGFR mutation.

Up to 95% of individuals with cancer-predisposing germline pathogenic variants in the U.S. remain unidentified, particularly among historically underserved populations.

CDK4/6 inhibitors (CDK4/6i) combined with hormone therapies have demonstrated clinical benefit in HR+, HER2- breast cancer patients. However, the onset of resistance remains a concern and highlights a need for therapeutic strategies to improve outcomes. The objective of this study was to develop an in vitro model to better understand the mechanisms of resistance to CDK4/6i + hormone therapies and identify therapeutic strategies with potential to overcome this resistance.

Anthracycline-containing neoadjuvant chemotherapy (NACT) is the standard treatment for early triple-negative breast cancer (eTNBC); however, it is associated with substantial toxicity. We performed whole transcriptome profiling of baseline tumor biopsies to identify gene networks predictive and prognostic for pathological complete response (pCR) and survival after de-escalated, anthracycline-free NACT in the WSG-ADAPT-TN trial (NCT01815242).

The addition of 1 year of palbociclib to endocrine therapy (ET) did not improve invasive disease-free survival (iDFS) compared with placebo in the PENELOPE-B trial. In this article we report the final survival results of the PENELOPE-B trial.

To evaluate secondary efficacy endpoints and safety for the ENGOT-OV16/NOVA (NCT01847274) trial of niraparib maintenance therapy after extended follow-up and vital-status-data retrieval. Previously reported analyses (data cutoff, October 1, 2020) indicated benefit of niraparib maintenance therapy beyond first progression, but overall survival (OS) analyses were limited by missing data.

Our goal was to evaluate the impact of level of androgen receptor (AR) expression on outcomes in women with estrogen receptor α (ER) positive breast cancer. We sought to corroborate our preclinical findings that AR-agonists were efficacious in patients with ER-positive tumors that also expressed high levels of AR.

Osimertinib-a third-generation epidermal growth factor receptor-tyrosine kinase inhibitor-is recommended as adjuvant therapy for resected stage IB-IIIA epidermal growth factor receptor-mutated non-small-cell lung cancer, based on significant disease-free survival (DFS) and overall survival improvement shown in the previously reported phase 3 ADAURA trial. A trend toward an increased DFS event rate after completion of 3 years adjuvant treatment in ADAURA suggests that some patients may benefit from longer adjuvant osimertinib treatment. We therefore explored whether tumor-informed, circulating tumor DNA-based, molecular residual disease (MRD) could predict recurrence in an exploratory post hoc analysis of 220 patients (n = 112 osimertinib; n = 108 placebo) from ADAURA. MRD preceded imaging DFS events in this study by a median of 4.7 (95% confidence interval, 2.2-5.6) months. DFS and MRD event-free rate at 36 months was 86% versus 36% for patients in the osimertinib versus placebo groups (hazard ratio, 0.23 (95% confidence interval, 0.15-0.36)). In the osimertinib group, DFS or MRD events were detected in 28 (25%) patients; most events occurred following osimertinib cessation (19 of 28, 68%) and within 12 months of stopping osimertinib (11 of 19, 58%). At 24 months after osimertinib, the DFS and MRD event-free rate was 66%. In this study, MRD preceded DFS events in most patients across both arms. DFS and MRD event-free status was maintained for most patients during adjuvant osimertinib treatment and posttreatment follow-up, with most MRD or DFS events occurring after osimertinib treatment discontinuation or completion. MRD detection could potentially identify patients who may benefit from longer adjuvant osimertinib, although this requires clinical confirmation. ClinicalTrials.gov identifier: NCT02511106 .
