Association of radiation-induced normal tissue toxicity with a high genetic risk for rheumatoid arthritis.

Purpose: Overlapping genes are involved with rheumatoid arthritis (RA) and DNA repair pathways. Therefore, we hypothesised that patients with a high polygenic risk score (PRS) for RA will have an increased risk of radiotherapy (RT) toxicity given the involvement of DNA repair.

Methods: Primary analysis was performed on 1494 prostate cancer, 483 lung cancer and 1820 breast cancer patients assessed for development of RT toxicity in the REQUITE study.

Professional-patient discrepancies in assessing lung cancer radiotherapy symptoms: An international multicentre study.

Background And Purpose: We investigate discrepancies in the assessment of treatment-related symptoms in lung cancer between healthcare professionals and patients, and factors contributing to these discrepancies.

Materials And Methods: Data from 515 participants in the REQUITE study were analysed. Five symptoms (cough, dyspnoea, bronchopulmonary haemorrhage, chest wall pain, dysphagia) were evaluated both before and after radiotherapy.

Prognostic and Predictive Biomarkers of Oligometastatic NSCLC: New Insights and Clinical Applications.

This review discusses the current data on predictive and prognostic biomarkers in oligometastatic NSCLC and discusses whether biomarkers identified in other stages and widespread metastatic disease can be extrapolated to the oligometastatic disease (OMD) setting. Research is underway to explore the prognostic and predictive value of biological attributes of tumor tissue, circulating cells, the tumor microenvironment, and imaging findings as biomarkers of oligometastatic NSCLC. Biomarkers that help define true OMD and predict outcomes are needed for patient selection for oligometastatic treatment, and to avoid futile treatments in patients that will not benefit from locoregional treatment.

Hippocampal avoidance prophylactic cranial irradiation (HA-PCI) for small cell lung cancer better preserves white matter networks compared to conventional PCI.

Background: Hippocampal avoidance during prophylactic cranial irradiation (HA-PCI) is proposed to reduce neurocognitive decline, while preserving the benefits of PCI. We evaluated whether (HA-)PCI induces changes in white matter (WM) microstructure and whether sparing the hippocampus has an impact on preserving brain network topology. Additionally, we evaluated associations between topological metrics with hippocampal volume and neuropsychological outcomes.

An international and multidisciplinary EORTC survey on resectability of stage III non-small cell lung cancer.

Introduction: The EORTC-Lung Cancer Group initiated a Delphi consensus process to establish a consensual definition of resectable stage III non-small cell lung cancer (NSCLC) for the use in clinical trials, including a systematic review, survey, and review of clinical cases. Here, the survey results are presented, aimed to identify areas of controversy.

Methods: A survey was distributed among the members of six international organizations related to lung cancer.
