Purpose: Tumor genomic testing (TGT) is standard-of-care for most patients with advanced/metastatic cancer. Despite established guidelines, patient education prior to TGT is frequently omitted. The purpose of this study was to evaluate the impact and durability of a concise 3-4 minute video for patient education prior to TGT in community versus academic sites and across cancer types. Patients and Methods: Patients undergoing standard-of-care TGT were enrolled at a tertiary academic institution ...

Multi-cancer early detection (MCED) tests can detect several cancer types and stages. We previously developed a methylation and protein (MP V1) MCED classifier. In this study, we present a refined MP V2 classifier, developed by evaluating model architectures that improved performance in prospectively enrolled case-control cohorts under standard testing conditions. The newly developed MP V2 classifier was trained to be more generalizable and achieve increased early-stage sensitivity at a target s...

Medical oncology education faces a dual crisis: knowledge velocity that outpaces static curricula and large language model (LLM) risks--hallucination and automation bias--that threaten the fidelity of AI-assisted learning. We present Onco-Shikshak V7, an AI-native adaptive learning platform that addresses both challenges through a unified cognitive architecture grounded in learning science. The system replaces isolated educational modules with four authentic clinical workflows--Morning Report, T...

Introduction: Manual data extraction from unstructured clinical notes is labor-intensive and impractical for large-scale clinical and research operations. Existing automated approaches typically require large language models, dedicated computational infrastructure, and/or task-specific fine-tuning that depends on curated data. The objective of this study is to enable accurate extraction with smaller locally deployed models using a disease-site specific pipeline and prompt configuration that are ...

BackgroundGynecological cancers and their treatments can compromise fertility, with profound psychosocial consequences for women of reproductive age. Yet, womens lived experiences of cancer-related infertility remain underexplored in low-resource settings, including Ghana. This study examined the impact of gynecological cancers on fertility among reproductive-aged women receiving care at Ho Teaching Hospital, Ghana. MethodsA qualitative descriptive design was used. Fourteen women aged 15-49 yea...

BackgroundTamoxifen is a cornerstone of endocrine treatment for hormone receptor-positive breast cancer, reducing recurrence and breast cancer-specific mortality. However, its use is associated with a small, yet clinically relevant, increase in uterine cancer. As diagnosis of this cancer remains symptom-triggered, it is essential for patients to be aware of this risk and report symptoms promptly for optimal outcomes. We therefore assessed risk awareness among breast cancer survivors while explor...

IntroductionDespite advancements in non-small cell lung cancer (NSCLC) management through the use of molecular biomarkers, the recently introduced 9th edition of the TNM staging system remains based exclusively on anatomic descriptors, with no consistently demonstrated improvement in risk stratification for early-stage disease. This study explores the integration of a molecular prognostic classifier into the conventional TNM staging system. MethodsWe analyzed 502 patients with stage I-III lung ...

BackgroundLeptomeningeal disease (LMD) is a serious complication of metastatic breast cancer (MBC) with poor survival. This single-institution retrospective study compares overall survival (OS) among MBC patients with LMD based on CSF parameters (glucose, protein, and WBC count) MethodologyMBC patients who were diagnosed with LMD between 2010-2023 at Wilmot Cancer Institute were screened for eligibility. Only those with available data on CSF glucose, protein, and WBC count were included. OS was...

BackgroundQuality-of-life (QoL) assessment is essential in breast cancer care, yet limited evidence describes how interrelated QoL domains change during pharmacotherapy. This study aimed to evaluate correlations among functional and symptom scales using the EORTC QLQ-C30 and QLQ-BR23, highlighting their ability to reveal multidimensional QoL patterns. MethodsA prospective observational study was conducted in two second-referral hospitals in Indonesia, enrolling 106 female breast cancer patients...

Background and ObjectivePatients with upper urinary tract urothelial carcinoma (UTUC) undergoing radical surgery are at high risk of developing intravesical recurrences (IVR). The biology of IVR after surgery for UTUC is poorly understood, and urine markers to replace cystoscopic surveillance of the bladder are lacking. Here, we characterized the genomic landscape of UTUC and paired IVR to discover therapeutic targets and identify diagnostic markers for IVR. MethodsWe performed targeted next-ge...

PurposeThis study evaluated the safety and effectiveness of an intraoral light-emitting diode (LED)-based photobiomodulation (PBM) device to reduce the incidence and severity of oral mucositis (OM) from intensity modulated radiation therapy (IMRT) for head and neck cancer (HNC). MethodsThis randomized, double-blind, sham-controlled trial enrolled patients with HNC undergoing high-dose IMRT over 6-8 weeks, with or without concurrent chemotherapy. Participants received daily 10-minute PBM or sham...

ImportancePersistent racial and ethnic disparities in breast and prostate cancer mortality are well documented. Most prior studies emphasize between-group differences and rely on population averages or single composite measures of social disadvantage, which can obscure high-need communities within groups. How socio-behavioral determinants of health vary within groups across local gradients of cancer mortality remains incompletely characterized. A framework that combines race- and cancer-specific...

BackgroundCystoscopy is a core component of haematuria investigations but is invasive and resource-intensive. GALEAS Bladder is a DNA-based diagnostic urine test that measures alterations in 23 bladder cancer-associated genes. ObjectiveTo assess the diagnostic performance and clinical utility of GALEAS Bladder as a molecular triage tool in real-world haematuria investigation pathways. MethodsPatients referred for urgent investigation of haematuria were prospectively enrolled across seven UK NH...
