Returning genetic risk information for hereditary cancers to participants in a population-based cohort study in Japan.

Large-scale population cohort studies that collect genomic information are tasked with returning an assessment of genetic risk for hereditary cancers to participants. While several studies have applied to return identified genetic risks to participants, comprehensive surveys of participants' understanding, feelings, and behaviors toward cancer risk remain to be conducted. Here, we report our experience and surveys of returning genetic risks to 100 carriers of pathogenic variants for hereditary cancers identified through whole genome sequencing of 50 000 individuals from the Tohoku Medical Megabank project, a population cohort study.

[Epigenome Diagnosis of Cancer-Focusing on Genome-Wide DNA Methylation Diagnosis of Colorectal Cancer for Predicting Sensitivity of Anti-EGFR Antibody Treatment].

Epigenetic regulation mechanisms such as DNA methylation and histone acetylation are important for controlling various biological phenomena by regulating gene expression at the genome level. They are reversible systems that change depending on environmental factors. Epigenetic abnormalities are associated with the onset of various diseases, including developmental and aging abnormalities, neurological disorders, and malignant tumors.

Pretreatment neutrophil-lymphocyte ratio as a prognostic factor in recurrent/metastatic head and neck cancer treated with pembrolizumab.

Pembrolizumab-containing regimens are the standard first-line treatment for recurrent/metastatic squamous cell carcinoma of the head and neck (R/M HNSCC). The neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein-to-albumin ratio (CAR) have been reported to be important prognostic factors in a variety of carcinomas, but none have been investigated in combination with pembrolizumab and chemotherapy or in first-line treatment. Seventy-four patients with R/M HNSCC received pembrolizumab-containing regimens at Tohoku University Hospital, Sendai, Japan, from April 2020 to March 2023.

Preferred and Actual Places of Death Among Patients with Advanced Cancer: A Single-centre Cohort Study in Japan.

Objectives: Achieving a 'good death' is one of the important goals of palliative care. Providing goal-concordant care and an environment tailored to the patient's preferences can contribute to a 'good death'. However, the concordance rate between the preferred and actual places of death among advanced cancer patients in Japan is less explored.
