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.

Polygenic score distribution differences across European ancestry populations: implications for breast cancer risk prediction.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.

An update on access to novel treatment for metastatic melanoma in Europe - A 2024 survey of the European melanoma registry and the European association of dermato-oncology.

Advances in cancer treatments have significantly improved their effectiveness, yet access to first-line therapies remains limited. A 2017 survey revealed that over 25 % of metastatic melanoma patients in Europe lacked access to recommended therapies. To address this, the European Association of Dermato-Oncology and the European Melanoma Registry conducted a follow-up study on the registration and reimbursement of first-line treatments.

Associations of intraoperative end-tidal CO levels with postoperative outcome-secondary analysis of a worldwide observational study.

Background: Patients receiving intraoperative ventilation during general anesthesia often have low end-tidal CO (etCO). We examined the association of intraoperative etCO levels with the occurrence of postoperative pulmonary complications (PPCs) in a conveniently-sized international, prospective study named 'Local ASsessment of Ventilatory management during General Anesthesia for Surgery' (LAS VEGAS).

Methods: Patients at high risk of PPCs were categorized as 'low etCO' or 'normal to high etCO' patients, using a cut-off of 35 mmHg.

Multicenter Evaluation of Morbidity and Predictors of Response to Imiquimod Treatment for Penile Intraepithelial Neoplasia.

Introduction And Objective: Imiquimod (IQ) is an immunomodulator used in the management of penile intraepithelial neoplasia (PeIN) lesions. However, IQ treatment may be associated with bothersome side effects (SEs). To date, studies reporting on this morbidity and evaluating predictors of response to IQ are scarce and included small cohorts.

Muscle atrophy and organ enlargement associated with quality of life during systemic therapy for melanoma: findings from an AI-based body composition analysis.

Introduction: Health-related quality of life (HRQoL) is emerging as an endpoint, adjunct to survival, in cancer treatment. For this reason, the European Organization for Research and Treatment of Cancer (EORTC) has developed standardized quality-of-life questionnaires to collect patient-reported outcome measurement (PROM), which so far have been widely used in clinical trials to evaluate the impact of new drugs on cancer patients. However, while these questionnaires comprehensively describe patient functions, little is known about their association with patient characteristics.

Win Ratio approach for the composite outcome of postoperative pulmonary complications: Secondary analysis of a harmonised and pooled database of three randomised clinical trials.

Background: The win ratio analysis method might provide new insight on the impact of positive end-expiratory pressure (PEEP) on clinical outcomes.

Objective: The aim is to re-analyse the results of the 'Re-evaluation of the effects of high PEEP with recruitment manoeuvres vs. low PEEP without recruitment manoeuvres during general anaesthesia for surgery' (REPEAT) study using the win ratio analysis.

Risk-based breast cancer screening: What are the challenges?

Population-based screening programs aim to detect the disease at an early stage, so less treatment will be needed as well as having better oncological outcomes when diagnosed earlier. In the majority of European countries, breast cancer screening programs are designed based on women age.Meta-analysis of randomized clinical trial data demonstrates a reduction in the relative risk of breast cancer mortality due to screening, which has been estimated to be approximately 20%.

Interval cancer risk after the upper age limit of screening has been reached: Informing risk stratification in FIT-based colorectal cancer screening.

Upper age limits are currently fixed for all fecal immunochemical test (FIT)-based colorectal cancer (CRC) screening programs. A risk-stratified upper age limit may be beneficial. Therefore, we assessed differences in interval CRC risk among individuals who had reached the upper age limit of screening (75 years).

Metastatic breast cancer patients' preferences for exercise programs: a latent class analysis using data from a survey in five European countries.

Purpose: We aimed to identify metastatic breast cancer (MBC) patients' preferences for exercise programs and identify patients' characteristics associated with these preferences, to facilitate implementation of exercise programs for MBC patients.

Methods: We used data from a multinational cross-sectional survey conducted among MBC patients. Patients reported their preferred exercise frequency, intensity, type, session duration, and supervision mode.

An early economic evaluation of active surveillance for low-risk ductal carcinoma .

Perform early economic evaluation comparing active surveillance (AS) to surgery for women with low-risk ductal carcinoma , a precursor of invasive breast cancer. A 10-year incremental costs (€) and quality-adjusted life years (QALYs) were compared between a simulated cohort of women undergoing breast conserving surgery ± radiotherapy, and a cohort with a low-risk subgroup undergoing AS using a semi-Markov model. Scenario and headroom analyses evaluated a better-performing biomarker to select low-risk women for AS.

Prevalence and impact of vulvar lesions diagnosed prior to vulvar squamous cell carcinoma: A population-based cohort study.

Objective: To systematically explore vulvar pathology diagnosed prior to vulvar squamous cell carcinoma (VSCC), as well as the association with tumor characteristics, stage and survival outcome, with the aim of improving vulvar cancer prevention strategies.

Methods: VSCC diagnosed between 2005 and 2019 were identified from a population-based cohort provided by the Dutch Nationwide Pathology Databank. Pathology reports were reviewed to identify vulvar pathology diagnosed before primary VSCC.

Measurement variability of radiologists when measuring brain tumors.

Background: In oncology trials, response evaluation criteria are pivotal in developing new treatments. This study examines the influence of measurement variability in brain lesions on response classification, considering long-standing cut-offs for progression and response were determined before the era of submillimeter resolutions of medical imaging.

Methods: We replicate a key study using modern radiological tools.

The DETECTION project part 1: An international Delphi survey about diagnostics and treatment of anterior mediastinal cystic lesions.

Background: Differentiating benign anterior mediastinal cysts from malignancies is challenging in clinical practice. International guidelines on optimal diagnostics and treatment for anterior mediastinal cystic lesions are lacking. The first part of the DETECTION project focuses on possible heterogeneity in diagnostics and treatment of anterior mediastinal cystic lesions among international thoracic medical experts.

Androgen receptor inhibition increases MHC Class I expression and improves immune response in prostate cancer.

Tumors escape immune detection and elimination through a variety of mechanisms. Here, we used prostate cancer as a model to examine how androgen-dependent tumors undergo immune evasion through downregulation of the major histocompatibility complex class I (MHCI). We report that response to immunotherapy in late-stage prostate cancer is associated with elevated MHC expression.

General Practitioners' Experiences With Implementing Colon or Prostate Cancer Survivorship Care in Primary Care: A Cross-Sectional Survey Nested Within Two Randomized-Controlled Trials.

Purpose: To evaluate general practitioners' (GPs) experiences with providing cancer survivorship care and explore readiness for implementation.

Methods: This cross-sectional survey study was nested within two randomized-controlled trials conducted in the Netherlands between 2015 and 2023, comparing GP- with specialist-led survivorship care for patients with colon or prostate cancer. An adapted version of the normalisation measure development (NoMAD) survey was distributed among participating GPs.

Multispectral Fluorescence Imaging as a Tool to Distinguish Pelvic Lymphatic Drainage Patterns During Robot-assisted Lymph Node Dissection in Prostate Cancer.

Background: The invasive nature of extended pelvic lymph node dissection (ePLND) prompts the need for alternative lymphatic mapping technologies. To change the focus to "sparing nodes that are not involved," the first step is to research the feasibility of intraoperatively distinguishing the lymph drainage patterns of the prostate from healthy organs.

Methods: We performed a prospective study (NCT05120973) that included 16 patients who underwent a robot-assisted radical prostatectomy + ePLND + sentinel node (using indocyanine green-Tc-nanocolloid).
