Differences in polygenic score distributions in European ancestry populations: implications for breast cancer risk prediction.

The 313-variant polygenic risk score (PRS) provides a promising tool for breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed. Here, we explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 225,105 female participants from the UK Biobank.

Survival difference between patients with single versus multiple metastatic lymph nodes and the role of histology in pathological stage II-N1 non-small cell lung cancer.

Background: Previous studies investigating whether metastatic lymph node count is a relevant prognostic factor in pathological N1 non-small cell lung cancer (NSCLC), showed conflicting results. Hypothesizing that outcome may also be related to histological features, we determined the prognostic impact of single versus multiple metastatic lymph nodes in different histological subtypes for patients with stage II-N1 NSCLC.

Methods: We performed a retrospective cohort study using data from the Netherlands Cancer Registry, including patients treated with a surgical resection for stage II-N1 NSCLC (TNM 7th edition) in 2010-2016.

Penile cancer care in the Netherlands: increased incidence, centralisation, and improved survival.

Objective: To evaluate penile squamous cell carcinoma (PSCC) incidence and centralisation trends in the Netherlands over the past three decades, as well as the effect of centralisation of PSCC care on survival.

Patients And Methods: In the Netherlands PSCC care is largely centralised in one national centre of expertise (Netherlands Cancer Institute [NCI], Amsterdam). For this study, the Netherlands Cancer Registry, an independent nationwide cancer registry, provided per-patient data on age, clinical and pathological tumour staging, follow-up, and vital status.

Translational insights and overall survival in the U31402-A-U102 study of patritumab deruxtecan (HER3-DXd) in EGFR-mutated NSCLC.

Background: Human epidermal growth factor receptor 3 (HER3) is broadly expressed in non-small-cell lung cancer (NSCLC) and is the target of patritumab deruxtecan (HER3-DXd), an antibody-drug conjugate consisting of a HER3 antibody attached to a topoisomerase I inhibitor payload via a tetrapeptide-based cleavable linker. U31402-A-U102 is an ongoing phase I study of HER3-DXd in patients with advanced NSCLC. Patients with epidermal growth factor receptor (EGFR)-mutated NSCLC that progressed after EGFR tyrosine kinase inhibitor (TKI) and platinum-based chemotherapy (PBC) who received HER3-DXd 5.

Unlocking the Potential of Adequate Bacillus Calmette-Guérin Immunotherapy in Very-high-risk Non-muscle-invasive Bladder Carcinoma: A Multicenter Analysis of Oncological Outcomes and Risk Dynamics.

Background: The European Association of Urology (EAU) recommends discussing upfront radical cystectomy for all patients with very high risk (VHR) non-muscle-invasive bladder carcinoma (NMIBC), but the role of bacillus Calmette-Guérin (BCG) treatment remains controversial.

Objective: To analyze oncological outcomes in VHR NMIBC patients (EAU risk groups) treated with adequate BCG.

Design, Setting, And Participants: A multi-institutional retrospective study involving patients with VHR NMIBC who received adequate BCG therapy from 2007 to 2020 was conducted.

TcPSMA-radioguided surgery in oligorecurrent prostate cancer: the randomised TRACE-II trial.

Objective: To investigate whether combination treatment of prostate-specific membrane antigen (PSMA)-based radioguided surgery (RGS) with short-term androgen deprivation therapy (ADT) improves oncological outcomes in men with oligorecurrent prostate cancer (PCa) as compared to treatment with short-term ADT only.

Methods: The TRACE-II study is an investigator-initiated, prospective, randomised controlled clinical trial. Patients (aged >18 years) with hormone-sensitive recurrent PCa after radical prostatectomy or radiotherapy (brachytherapy or external beam radiotherapy), with involvement of ≤2 lymph nodes or local oligorecurrent disease within the pelvis as determined by PSMA positron emission tomography (PET)/computed tomography (CT) are randomly assigned in a 1:1 ratio between 6-month ADT (Arm A) or 6-month ADT plus RGS (Arm B).

Dropout from exercise trials among cancer survivors-An individual patient data meta-analysis from the POLARIS study.

Introduction: The number of randomized controlled trials (RCTs) investigating the effects of exercise among cancer survivors has increased in recent years; however, participants dropping out of the trials are rarely described. The objective of the present study was to assess which combinations of participant and exercise program characteristics were associated with dropout from the exercise arms of RCTs among cancer survivors.

Methods: This study used data collected in the Predicting OptimaL cAncer RehabIlitation and Supportive care (POLARIS) study, an international database of RCTs investigating the effects of exercise among cancer survivors.

Oncologic outcomes of screen-detected and non-screen-detected T1 colorectal cancers.

Background: The incidence of T1 colorectal cancer (CRC) has increased with the implementation of CRC screening programs. It is unknown whether the outcomes and risk models for T1 CRC based on non-screen-detected patients can be extrapolated to screen-detected T1 CRC. This study aimed to compare the stage distribution and oncologic outcomes of T1 CRC patients within and outside the screening program.

Does Retzius-Sparing robot-assisted radical prostatectomy guarantee optimal urinary continence recovery across all ages?

The association between age at surgery and urinary continence (UC) recovery after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) is not well established. We addressed this knowledge gap, relying on a large series of 1,417 patients treated with RS-RARP at a high-volume centre between 2010 and 2021. Multivariable logistic models, as well as LOESS plot functions were performed.

Image-based multiplex immune profiling of cancer tissues: translational implications. A report of the International Immuno-oncology Biomarker Working Group on Breast Cancer.

Recent advances in the field of immuno-oncology have brought transformative changes in the management of cancer patients. The immune profile of tumours has been found to have key value in predicting disease prognosis and treatment response in various cancers. Multiplex immunohistochemistry and immunofluorescence have emerged as potent tools for the simultaneous detection of multiple protein biomarkers in a single tissue section, thereby expanding opportunities for molecular and immune profiling while preserving tissue samples.

New EAU/ASCO guideline recommendations on sentinel node biopsy for penile cancer and remaining challenges from a nuclear medicine perspective.

Introduction: The European Association of Urology (EAU) and the American Society of Clinical Oncology (ASCO) recently issued updated guidelines on penile cancer, emphasising dynamic sentinel node biopsy (DSNB) as the preferred method for surgical staging among patients with invasive penile tumours and no palpable inguinal lymphadenopathy. This paper outlines the rationale behind this new recommendation and describes remaining challenges, as well as strategies for promoting DSNB worldwide.

Main Text: DSNB offers high diagnostic accuracy with the lowest postoperative complications compared to open or minimally invasive inguinal lymph node dissection (ILND), prompting its preference in the new guidelines.

Safety and Feasibility of Intraoperative High PEEP Titrated to the Lowest Driving Pressure (ΔP)-Interim Analysis of DESIGNATION.

Uncertainty remains about the best level of intraoperative positive end-expiratory pressure (PEEP). An ongoing RCT ('DESIGNATION') compares an 'individualized high PEEP' strategy ('iPEEP')-titrated to the lowest driving pressure (ΔP) with recruitment maneuvers (RM), with a 'standard low PEEP' strategy ('low PEEP')-using 5 cm HO without RMs with respect to the incidence of postoperative pulmonary complications. This report is an interim analysis of safety and feasibility.

Neoadjuvant atezolizumab plus chemotherapy in gastric and gastroesophageal junction adenocarcinoma: the phase 2 PANDA trial.

Gastric and gastroesophageal junction (G/GEJ) cancers carry a poor prognosis, and despite recent advancements, most patients die of their disease. Although immune checkpoint blockade became part of the standard-of-care for patients with metastatic G/GEJ cancers, its efficacy and impact on the tumor microenvironment (TME) in early disease remain largely unknown. We hypothesized higher efficacy of neoadjuvant immunotherapy plus chemotherapy in patients with nonmetastatic G/GEJ cancer.

Phenotype-guided targeted therapy based on functional signal transduction pathway activity in recurrent ovarian cancer patients: The STAPOVER study protocol.

Objective: Ovarian cancer is the fifth cause of cancer-related death among women. The benefit of targeted therapy for ovarian cancer patients is limited even if treatment is stratified by molecular signature. There remains a high unmet need for alternative diagnostics that better predict targeted therapy, as current diagnostics are generally inaccurate predictors.

International case series of metastasis to penis.

Objectives: To evaluate clinical characteristics associated with survival in patients with metastases to the penis.

Methods: After approval by the IRB, records of collaborating centres in Leuven, London, Rostock, Amsterdam and Tampa were screened for men presenting with metastatic disease to penis. Multivariate logistic regression analyses were used to identify covariables associated with survival.

Quality assurance of radiation therapy after breast-conserving surgery among patients in the BOOG 2013-08 trial.

Background And Purpose: In the BOOG 2013-08 trial (NCT02271828), cT1-2N0 breast cancer patients were randomized between breast conserving surgery with or without sentinel lymph node biopsy (SLNB) followed by whole breast radiotherapy (WBRT). While awaiting primary endpoint results (axillary recurrence rate), this study aims to perform a quality assurance analysis on protocol adherence and (incidental) axillary radiation therapy (RT) dose.

Materials And Methods: Patients were enrolled between 2015 and 2022.

Association of metastatic pattern in breast cancer with tumor and patient-specific factors: a nationwide autopsy study using artificial intelligence.

Background: Metastatic spread is characterized by considerable heterogeneity in most cancers. With increasing treatment options for patients with metastatic disease, there is a need for insight into metastatic patterns of spread in breast cancer patients using large-scale studies.

Methods: Records of 2622 metastatic breast cancer patients who underwent autopsy (1974-2010) were retrieved from the nationwide Dutch pathology databank (PALGA).

Retzius-Sparing Robotic-Assisted Prostatectomy: Technical Challenges for Surgeons and Key Prospective Refinements.

Robotic-assisted radical prostatectomy (RARP) is the gold standard for localized prostate cancer. Several RARP approaches were developed and described over the years, aimed at improving oncological and functional outcomes. In 2010, Galfano et al described a new RARP technique, known as Retzius-sparing RARP (RS-RARP), a posterior approach through the Douglas space that spares the anterior support structures involved with urinary continence and sexual potency.

Non-therapeutic plasma levels in individuals utilizing curcumin supplements in daily life.

Introduction: The spice curcumin and its metabolites are widely used by cancer patients but have not shown proven health benefits in clinical studies, likely due to low plasma concentrations after oral intake. However, public interest in curcumin continues to grow, and companies claim enhanced absorption in their formulations. This study aims to determine if daily oral intake of curcumin leads to sufficient plasma concentrations for health effects.
