Fear of cancer recurrence (FCR) is a common and distressing condition among adolescents and young adults (AYAs). This study aims to investigate the efficacy of digital interventions, including distress screening-based information provision and smartphone problem-solving therapy, on common psychological distress, especially FCR, in AYA patients with cancer. Participants will be 224 AYA outpatients with cancer aged 15-39 years who will be randomly assigned to either an 8-week smartphone-based intervention or a waitlist control group.

Cross-sectional study of therapy-related expectations/concerns of patients with metastatic renal cell carcinoma and physicians in Japan.

Objective: To achieve patient-centricity in metastatic renal cell carcinoma (mRCC) treatment, it is essential to clarify the differences in perspectives between patients and physicians. This cross-sectional analysis of a web survey aimed to clarify the differences in expectations and concerns between mRCC patients and physicians regarding systemic mRCC therapy in Japan.

Methods: Surveys from 83 patients and 165 physicians were analyzed.

Financial Toxicity in Japanese Patients with Metastatic Renal Cell Carcinoma: A Cross-Sectional Study.

Information on the financial toxicity experienced by Japanese patients with metastatic renal cell carcinoma (mRCC) is lacking, even though Japan has its own unique public health insurance system. Thus, a web-based survey was conducted to evaluate the financial toxicity experienced by Japanese mRCC patients using the COmprehensive Score for financial Toxicity (COST) tool. This study enrolled Japanese patients who underwent, or were undergoing, systemic therapy for mRCC.

Shared decision-making support program for older patients with advanced cancer using a question prompt list and geriatric assessment: A pilot randomized controlled trial.

Introduction: Older patients with cancer are less likely to express their treatment preferences than younger patients. Question prompt lists (QPLs) facilitate communication between patients and physicians. Geriatric assessment (GA) is recommended when older patients with cancer make treatment decisions.

Patients' perceptions of patient-centered communication with healthcare providers and associated factors in Japan - The INFORM Study 2020.

Objective: To describe patients' perceptions of the patient-centeredness of their communication with healthcare providers in Japan, and to examine factors associated with these perceptions.

Methods: We analyzed the cross-sectional data from the INFORM Study 2020, which is a nationwide survey on health information access in Japan. A total of 3605 respondents completed the survey.

A feasibility study of provider-level implementation strategies to improve access to colorectal cancer screening for patients with schizophrenia: ACCESS2 (N-EQUITY 2104) trial.

Background: People with schizophrenia have a lower colorectal screening rate than the general population. A previous study reported an intervention using case management to encourage colorectal cancer screening for patients with schizophrenia in psychiatric outpatient settings. In this feasibility study, we developed provider-level implementation strategies and evaluated the feasibility of conducting a definitive trial in terms of the penetration of the intervention assessed at the patient level.

Prevalence of psychological distress and associated factors among patients undergoing comprehensive genomic profiling testing: protocol for a multicentre, prospective, observational study.

Introduction: Since May 2019, comprehensive genomic profiling (CGP) has been covered by Japan's health insurance system for patients with solid tumours that have progressed on standard chemotherapy, rare tumours or tumours of unknown primary origin. Although CGP has the potential to identify actionable mutations that can guide the selection of genomically matched therapies for patients with advanced cancer and limited treatment options, less than 10% of patients benefit from CGP testing, which may have a negative impact on patients' mental status. The aim of this study is to investigate the prevalence of psychological distress and associated factors among patients with advanced cancer who are undergoing CGP testing across Japan.

Barriers and facilitators to implementing geriatric assessment in daily oncology practice in Japan: A qualitative study using an implementation framework.

Introduction: Various guidelines recommend geriatric assessment (GA) for older adults with cancer, but it is not widely implemented in daily practice. This study uses an implementation framework to comprehensively and systematically identify multi-level barriers and facilitators to implementing GA in daily oncology practice.

Materials And Methods: We conducted 16 semi-structured interviews with healthcare providers in 10 designated cancer hospitals in Japan, using purposive and convenience sampling.

Cancer treatment-related financial toxicity in Japan: a scoping review.

Financial toxicity during cancer survival has been studied mainly in the United States; 47-49% of cancer survivors reported financial hardships and 12-63% reported debt owing to treatment costs. Financial toxicity is influenced by each country's economic status and healthcare system. We aimed to review the evidence on financial toxicity in Japan.

Validation of the Japanese version of the full and short form Trust in Oncologist Scale.

Objectives: This study aimed to validate the Japanese versions of the Trust in Oncologist Scale (TiOS-J) and the TiOS-Short Form (TiOS-SF-J).

Methods: A cross-sectional web-based survey was conducted among cancer patients in Japan. The forward-backward translation method was used to develop the TiOS-J.

Objective: To develop the Japanese version of the Patient Satisfaction Questionnaire (PSQ-J) and examine its validity and reliability.

Methods: A cross-sectional, web-based survey was conducted among cancer patients in Japan. The PSQ-J was developed following the forward-backward translation method, using a numerical rating scale.

A multi-centre, double-blind, randomized, placebo-controlled trial to evaluate the effectiveness and safety of ramelteon for the prevention of postoperative delirium in elderly cancer patients: a study protocol for JORTC-PON2/J-SUPPORT2103/NCCH2103.

Postoperative delirium is an important issue in cancer patients, affecting surgical outcomes and the quality of life. Ramelteon is a melatonin receptor agonist with high affinity for MT1 and MT2 receptors. Clinical trials and observational studies in Japan, including in surgical cancer patients, have shown efficacy of ramelteon in delirium prevention, with no serious safety concerns.

Interactive assistance via eHealth for small- and medium-sized enterprises' employer and health care manager teams on tobacco control (eSMART-TC): protocol for a cluster randomized hybrid type II trial (N-EQUITY2101/J-SUPPORT2102).

Background: Tobacco control should be a higher public health priority in Japan. Some workplaces provide smoking cessation support and connect employees to effective smoking cessation treatments such as outpatient clinics. However, tobacco control measures have not been sufficiently implemented in Japan, especially in small- and medium-sized enterprises (SMEs), where resources are limited.

Prevalence of psychological distress, quality of life, and satisfaction among patients and family members following comprehensive genomic profiling testing: Protocol of the Quality of life for Cancer genomics and Advanced Therapeutics (Q-CAT) study.

Precision medicine is rapidly changing the diagnostic and treatment spectrum of oncology. In May 2019, comprehensive genomic profiling (CGP) (somatic and/or germline) was approved for reimbursement in Japan. While the promise of novel and targeted therapies has elevated hopes for the benefits of CGP, the lack of relevant genomic findings and/or limited access to relevant therapies remain important themes in this field.

Optimization of smartphone psychotherapy for depression and anxiety among patients with cancer using the multiphase optimization strategy (MOST) framework and decentralized clinical trial system (SMartphone Intervention to LEssen depression/Anxiety and GAIN resilience: SMILE AGAIN project): a protocol for a randomized controlled trial.

Background: Cancer patients experience various forms of psychological distress. Their distress, mainly in the form of depression and anxiety, leads to poor quality of life, increased medical spending due to frequent visits, and decrease in treatment adherence. It is estimated that 30-50% among them would require support from mental health professionals: in reality, much less actually receive such support partly due to a shortage of qualified professionals and also due to psychological barriers in seeking such help.

Epidemiology of skin cancer based on Japan's National Cancer Registry 2016-2017.

Skin cancer is most frequently diagnosed in the White population. However, its subtypes and epidemiology in Japan are understudied. We aimed to elucidate skin cancer incidence in Japan based on the National Cancer Registry, a new nationwide integrated population-based registry.

Perceptions toward issues in cancer care for people with mental illness among psychiatric care providers: A questionnaire study.

Objectives: To reduce cancer care disparities in people with mental illness, this study aimed to quantify psychiatric care providers' perceptions regarding issues that are insufficiently addressed or difficult to address.

Methods: Psychiatric care providers at 23 psychiatric hospitals in Japan were surveyed using mail questionnaires. Respondents were asked to rate 15 items with four categories related to insufficiencies/difficulties in cancer care for patients with mental illness on a five-point Likert scale.

Effectiveness of a facilitation programme using a mobile application for initiating advance care planning discussions between patients with advanced cancer and healthcare providers: protocol for a randomised controlled trial (J-SUPPORT 2104).

Introduction: Timely implementation of the discussion process of advance care planning (ACP) is recommended. The communication attitude of healthcare providers is critical in ACP facilitation; thus, improving their communication attitudes may reduce patient distress and unnecessary aggressive treatment while enhancing care satisfaction. Digital mobile devices are being developed for behavioural interventions owing to their low space and time restrictions and ease of information sharing.
