Pooled safety analysis and management of sotorasib-related adverse events in KRAS G12C-mutated advanced non-small cell lung cancer.

Introduction: We describe the safety of sotorasib monotherapy in patients with KRAS G12C-mutated advanced non-small cell lung cancer (NSCLC) and discuss practical recommendations for managing key risks.

Methods: Incidence rates of treatment-related adverse events (TRAEs) were pooled from 4 clinical trials: CodeBreaK 100 (NCT03600883), CodeBreaK 101 (NCT04185883), CodeBreaK 105 (NCT04380753), and CodeBreaK 200 (NCT04303780) and graded according to CTCAE v5.0.

Tremelimumab plus durvalumab prior to chemoradiotherapy in unresectable, locally advanced non-small cell lung cancer: the Induction trial.

Background: The phase I Induction trial (NCT04287894) assessed the feasibility and safety of induction immunotherapy (IIT) prior to concurrent chemoradiotherapy (cCRT) in patients with locally advanced non-small cell lung cancer (NSCLC).

Methods: Patients with unresectable stage II/III NSCLC were eligible for inclusion. Patients received either one cycle of tremelimumab (75mg) with two cycles of durvalumab (1500mg) in cohort I, one cycle of tremelimumab (300mg) with two cycles of durvalumab in cohort II or one cycle of tremelimumab (300mg) with one cycle of durvalumab in cohort III.

AAPM Task Group Report 274: Fluence rate dosimetry for photodynamic therapy (PDT).

Photodynamic therapy (PDT) is a treatment modality clinically approved for several oncologic indications, including esophageal and endobronchial cancers, precancerous conditions including Barrett's esophagus and actinic keratosis, and benign conditions like age-related macular degeneration. While it is currently clinically underused, PDT is an area of significant research interest. Because PDT relies on the absorption of light energy by intrinsic or administered absorbers, the dosimetric quantity of interest is the absorbed energy per unit mass of tissue, proportional to the fluence rate of light in tissue.

Assessing fetal radiation dose from iodine-125 seeds in pregnant breast cancer patients: an updated model.

The treatment of breast cancer during pregnancy requires careful consideration of consequences for both maternal and fetal health. In non-pregnant patients, the use of radioactive iodine-125 (125I)-seeds is standard practice for localising non-palpable breast tumors before breast-conserving surgery. However, the use of 125I-seeds in pregnant patients has been avoided due to concerns about fetal radiation exposure.

Conquering Overtreatment of DCIS: Lessons from PRECISION.

As we cannot reliably distinguish indolent, low-risk ductal carcinoma in situ (DCIS) from potentially progressive, high-risk DCIS, all women with DCIS diagnosis undergo intensive treatment without any benefit. The PREvent ductal Carcinoma In Situ Invasive Overtreatment Now team was established to unravel DCIS biology and develop new multidisciplinary approaches for accurate risk stratification to tackle the global problem of DCIS overdiagnosis and overtreatment. See related article by Bressan et al.

Benefit and Harms of Radical Nephroureterectomy as Part of a Multimodal Treatment Strategy for Upper Tract Urothelial Carcinoma Patients Presenting with Clinical Evidence of Regional Lymph Node Metastasis: A Systematic Review and Meta-analysis by the European Association of Urology Guidelines.

Background And Objective: Given the uncertainty regarding the role of radical nephroureterectomy (RNU) as part of a multimodal treatment strategy for upper tract urothelial carcinoma (UTUC) patients with cN+ disease, we aimed to perform a systematic review and meta-analysis of the corresponding literature.

Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, we identified 17 observational comparative and noncomparative studies, published between January 2000 and September 2024, evaluating UTUC patients with cTanyN+M0 disease (P) who received RNU as part of a multimodal treatment strategy (I), as compared with any treatment strategy if applicable (C), to assess oncological or postoperative outcomes (O). Meta-analyses were further performed, as appropriate.

Deintensification of Radiotherapy Use in Treatment of Ductal Carcinoma In Situ in the Netherlands-A Nationwide Overview From 2008 Until 2022.

Aims: Ductal Carcinoma In Situ (DCIS) treated by breast-conserving surgery followed by radiotherapy aims to decrease the probability of locally recurrent disease. The role of whole breast irradiation, specifically in DCIS having low recurrence risk and low risk of becoming invasive, is increasingly debated. Also, the added value of applying boost irradiation in DCIS has been questioned.

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.

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.

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).
