Business case for psychosocial interventions in clinics: potential for decrease in treatment discontinuation and costs.

Research Question: From a value-based healthcare (VBHC) perspective, does an assessment of clinical outcomes and intervention costs indicate that providing cognitive behavioural therapy (CBT) or mindfulness to women seeking fertility treatment add value compared with no such intervention?

Design: Proof-of-concept business case based on a VBHC perspective that considers clinical outcomes and costs. Potential effects on psychological and fertility outcomes were based on existing research. Cost outcomes were estimated with a costing model for the Dutch fertility treatment setting.

Performance of a RAD51-based functional HRD test on paraffin-embedded breast cancer tissue.

Purpose: BRCA-deficient breast cancers (BC) are highly sensitive to platinum-based chemotherapy and PARP inhibitors due to their deficiency in the homologous recombination (HR) pathway. However, HR deficiency (HRD) extends beyond BRCA-associated BC, highlighting the need for a sensitive method to enrich for HRD tumors in an alternative way. A promising approach is the use of functional HRD tests which evaluate the HR capability of tumor cells by measuring RAD51 protein accumulation at DNA damage sites.

The PCQ-Infertility Revised: A New Digital Instrument to Measure Treatment Satisfaction of Fertility Patients.

Background: One of the key dimensions of healthcare quality is patient-centeredness, which represents how well healthcare is geared towards patients' needs and wishes. Many questionnaires that measure the patient-centeredness are long and complicated, eliciting non-response or careless responding. Moreover, responses to some commonly used questionnaires are difficult to interpret.

RAD51 as a functional biomarker for homologous recombination deficiency in cancer: a promising addition to the HRD toolbox?

Introduction: Carcinomas with defects in the homologous recombination (HR) pathway are sensitive to PARP inhibitors (PARPi). A robust method to identify HR-deficient (HRD) carcinomas is therefore of utmost clinical importance. Currently, available DNA-based HRD tests either scan HR-related genes such as and for the presence of pathogenic variants or identify HRD-related genomic scars or mutational signatures by using whole-exome or whole-genome sequencing data.

The RAD51-FFPE Test; Calibration of a Functional Homologous Recombination Deficiency Test on Diagnostic Endometrial and Ovarian Tumor Blocks.

PARP inhibitor (PARPi) sensitivity is related to tumor-specific defects in homologous recombination (HR). Therefore, there is great clinical interest in tests that can rapidly and reliably identify HR deficiency (HRD). Functional HRD tests determine the actual HR status by using the (dis)ability to accumulate RAD51 protein at sites of DNA damage as read-out.

The RECAP Test Rapidly and Reliably Identifies Homologous Recombination-Deficient Ovarian Carcinomas.

Recent studies have shown that the efficacy of PARP inhibitors in epithelial ovarian carcinoma (EOC) is related to tumor-specific defects in homologous recombination (HR) and extends beyond deficient EOC. A robust method with which to identify HR-deficient (HRD) carcinomas is therefore of utmost clinical importance. In this study, we investigated the proficiency of a functional HR assay based on the detection of RAD51 foci, the REcombination CAPacity (RECAP) test, in identifying HRD tumors in a cohort of prospectively collected epithelial ovarian carcinomas (EOCs).

An organoid platform for ovarian cancer captures intra- and interpatient heterogeneity.

Ovarian cancer (OC) is a heterogeneous disease usually diagnosed at a late stage. Experimental in vitro models that faithfully capture the hallmarks and tumor heterogeneity of OC are limited and hard to establish. We present a protocol that enables efficient derivation and long-term expansion of OC organoids.

Frequent Homologous Recombination Deficiency in High-grade Endometrial Carcinomas.

Purpose: The elevated levels of somatic copy-number alterations (SCNAs) in a subset of high-risk endometrial cancers are suggestive of defects in pathways governing genome integrity. We sought to assess the prevalence of homologous recombination deficiency (HRD) in endometrial cancers and its association with histopathologic and molecular characteristics.

Experimental Design: Fresh tumor tissue was prospectively collected from 36 endometrial cancers, and functional HRD was examined by the ability of replicating tumor cells to accumulate RAD51 protein at DNA double-strand breaks (RAD51 foci) induced by ionizing radiation.
