Response to drug therapy in individual colorectal cancer (CRC) patients is associated with tumour biology. Here we describe the genomic landscape of tumour samples of a homogeneous well-annotated series of patients with metastatic CRC (mCRC) of two phase III clinical trials, CAIRO and CAIRO2. DNA copy number aberrations of 349 patients are determined. Within three treatment arms, 194 chromosomal subregions are associated with progression-free survival (PFS; uncorrected single-test P-values <0.005). These subregions are filtered for effect on messenger RNA expression, using an independent data set from The Cancer Genome Atlas which returned 171 genes. Three chromosomal regions are associated with a significant difference in PFS between treatment arms with or without irinotecan. One of these regions, 6q16.1-q21, correlates in vitro with sensitivity to SN-38, the active metabolite of irinotecan. This genomic landscape of mCRC reveals a number of DNA copy number aberrations associated with response to drug therapy.

Clinical judgment of the need for professional mental health care in patients with cancer: a qualitative study among oncologists and nurses

Jeanet F. Karchoud, Anja J. Th C. M. de Kruif, Femke Lamers, Myra E. van Linde, Joyce M. Van Dodewaard-de Jong, Annemarie M. J. Braamse, Mirjam A. G. Sprangers, Aartjan T. F. Beekman, Henk M. W. Verheul, Joost Dekker

Summary: This study explores the indicators and strategies used by oncologists and nurses to determine the need for professional mental health care in cancer patients. The findings suggest that oncologists and nurses consider multiple factors, including the patient's emotional well-being and specific indicators of emotional problems, when making the decision to refer patients for professional mental health care.

Summary: This study developed a noninvasive genetic assay to detect genetically altered fields in the oral cavity. The assay demonstrated high accuracy and predicted the development of oral squamous cell carcinoma in high-risk individuals. This method can be used for cancer screening in high-risk populations and to map the extent of lesions beyond what is visible.

Summary: This study investigated whether combining clinical, molecular genotype, and radiomics features can improve the outcome prediction of patients with aggressive B-cell lymphoma. The results showed that adding radiomics features improved the model performance and positive predictive values, aiding in the identification of poor prognosis patients.

Valkenburg, Mark Sausen, Samuel Angiuoli, Robert B. Scharpf, Cornelis J. A. Punt, Gerrit A. Meijer, Victor E. Velculescu, Remond J. A. Fijneman

Summary: The study demonstrates that accurate monitoring of treatment response using ctDNA can be achieved in a tumor tissue-independent manner by combining cfDNA and patient-matched WBC genomic DNA analysis. This approach prevents false-positives caused by germline or hematopoietic variants and provides more predictive information on overall survival compared to standard radiological evaluation. Additionally, ctDNA analysis reveals potential therapy resistance mutations in a significant portion of patients.

Summary: We evaluated the potential efficacy of adding anti-EGFR therapy to anti-VEGF therapy in a subgroup of patients with metastatic colorectal cancer. The retrospective study (CAIRO2 trial, n = 736) showed no benefit of anti-EGFR addition within the subgroup, but an overall survival increase of 6.5 months compared to the original trial.

Summary: This study developed a micro-costing framework for consistent cost calculation of ctDNA testing. The framework takes into account the complete diagnostic workflow of ctDNA testing, including costs for personnel, materials, equipment, overhead, and failures. Evaluations and case studies were performed, showing a wide range of costs per sample and the sensitivity to platform, setting, and testing volume. An open access tool is provided for laboratory-specific calculations and exploring the total costs and impact of alternative prices or assumptions.

Clonal Patterns Between Pouch Neoplasia and Prior Colorectal Neoplasia in Inflammatory Bowel Disease Patients: An Exploratory Cohort Study

Summary: The presence of previous colorectal neoplasia is the most significant indicator for the development of pouch neoplasia in inflammatory bowel disease. However, the underlying mechanism remains unknown. Our study found evidence of clonality between colorectal and pouch neoplasia in 30% of patients, suggesting that most pouch neoplasia develops independently from prior colorectal lesions.

Summary: This study investigates the impact of cell size and ploidy on FISH results. The results show that in liver cell nuclei, the number of FISH signals increases with nuclear size and section thickness. In non-small cell lung cancer cases, tumor cells with higher ploidy levels and nuclear size have an increased chance of single signals. In addition, no rearrangements were found in lung cancer samples with borderline ALK FISH results, proving a false positive result.

Outcome prediction by interim positron emission tomography and IgM monoclonal gammopathy in diffuse large B-cell lymphoma

Summary: In DLBCL, a positive interim PET scan predicts treatment failure, and combining it with the presence of an IgM gammopathy can improve prediction. The combination of interim PET and IgM gammopathy can dichotomize the population into high-risk and low-risk groups with significantly different outcomes. Only the interim PET result and IgM gammopathy status were significantly associated with outcome, making them important factors in risk-adapted treatment strategies.

Schoen, Kevin Selby, Harminder Singh, Robert J. C. Steele, Joseph J. Y. Sung, Erin Leigh Symonds, Sidney J. Winawer

Summary: New non-invasive tests for colorectal cancer (CRC) are emerging, making it challenging to conduct trials with mortality reduction as the main goal. A formal consensus approach involving experts resulted in the revision of previously established principles and the emergence of twelve new principles. The effectiveness of a new test can be evaluated by comparing it with an established non-invasive test, with the faecal immunochemical test considered as the appropriate comparator. Flexible adjustment of the new test's positivity threshold is desirable to meet different screening goals and requirements. A four-phased approach is proposed for the evaluation of new tests, including small studies, prospective estimation of accuracy, evaluation in screening populations, and monitoring for missed lesions.

Prognostic Value of T-Cell Density in the Tumor Center and Outer Margins in Gastric Cancer

Tanya T. D. Soeratram, Hedde D. Biesma, Jacqueline M. P. Egthuijsen, Elma Meershoek-Klein Kranenbarg, Henk H. Hartgrink, Cornelis J. H. van de Velde, Aart Mookhoek, Erik van Dijk, Yongsoo Kim, Bauke Ylstra, Hanneke W. M. van Laarhoven, Nicole C. T. van Grieken

Summary: Tumor-infiltrating lymphocytes are important for the survival of gastric cancer patients, and T-cell densities in different regions of the tumor can serve as prognostic markers. CD8OIM and FOXP3TC are identified as key factors for survival, and the combination of their densities can stratify patients into distinct subgroups with different prognosis. These immune subgroups are independent predictors for cancer-specific survival in resectable gastric cancer.

Summary: In order to understand the clinical relevance of the tumor microenvironment (TME), it is important to study the interactions between malignant and non-malignant cells in clinical samples. Researchers have developed a computational framework to comprehensively analyze the spatial context of the TME, including close and long-distance interactions between different cell types. This framework was applied to imaging data from 88 primary central nervous system lymphomas, revealing significant prognostic subgroups mainly determined by the spatial context. The results highlight the importance of spatial context in predicting patient survival, particularly in relation to macrophage infiltration near specific cell types.
