  PURPOSE: Prostate cancer is under-researched in many Asian countries because the paucity of comprehensive cancer registries has prevented large studies from comparing primary prostate cancer therapies. We aimed to provide further insights into recent trends in primary prostate cancer management across multiple Asian countries and regions according to universal health coverage. METHODS: This is part of the Asian Prostate Cancer (A-CaP), a prospective and multicenter study conducted in 12 Asian countries. The study cohort comprised patients newly diagnosed between January 2016 and December 2018. Patients were allocated to three categories according to the universal health coverage effective coverage index (Category 1 ≥ 80; Category 2, 70-79; and Category 3, < 70). We assessed primary management of prostate cancer according to these categories and by clinic pathological characteristics such as clinical stage, and D'Amico risk group. RESULTS: In total, 34,994 patients were included in the final analysis. Category 1 had the highest proportion of patients diagnosed at early stages and Category 3 had the highest proportion of patients diagnosed at advanced stages. Most patients in Category 1 had undergone computed tomography scans, magnetic resonance imaging, and bone scans. In contrast, only 1.7% and 5.4% of men in Categories 2 and 3, respectively, had undergone all three of these investigations. The proportion of patients who had undergone radiation and androgen deprivation therapy as primary treatment was highest in Category 1, whereas the rate of conservative management was highest in Category 2. More patients in Category 3 than in the other two categories had undergone radical prostatectomy, but fewer had been treated with radiation therapy. CONCLUSIONS: Our findings highlighted differences in patterns of treatment of newly diagnosed prostate cancer across 12 Asian countries and regions and suggest that, despite guidelines, health access affects treatment received.

  　View Summary

  AIM: The aim of this study was to investigate trends in cancer screening participation among people with severe mental illness (PSMI) from periods before and after the COVID-19 pandemic. METHODS: In this repeated cross-sectional study, we used anonymized datasets on municipal cancer screening participation among PSMI in Okayama City. The data covered fiscal year (FY) 2018 to FY2022; we used the municipal cancer screening database and Medical Payment for Services and Supports for Persons with Disabilities. PSMI were defined as those with schizophrenia or related psychotic disorders (F20-29) or bipolar disorder (F30 or F31), identified using International Classification of Diseases, Tenth Revision, codes. The analysis included men and women aged 40-69 years for colorectal and lung cancer screening; men and women aged 50-69 years for gastric cancer screening; women aged 40-69 years for breast cancer screening; and women aged 20-69 years for cervical cancer screening. Municipal cancer screening rates among PSMI were calculated for each FY. RESULTS: For all cancer types, cancer screening rates for PSMI in FY2020 (colorectal: 9.0%; lung: 11.6%; gastric: 4.9%; breast: 6.2%; and cervical: 6.1%) were lower than the rates in FY2019 (11.5%, 14.0%, 6.5%, 9.3%, and 8.3%, respectively). In FY2022, the rates (9.9%, 12.9%; 5.3%; 8.0%, and 6.9%, respectively) recovered, but remained low. CONCLUSION: This study showed that cancer screening rates among PSMI were very low, both before and after the COVID-19 pandemic. Efforts to encourage participation in cancer screening in this population are urgently needed.

  　View Summary

  BACKGROUND: In previous large-scale studies conducted through 2010, androgen deprivation therapy (ADT) was the most common initial treatment for prostate cancer patients in Japan. However, recent advancements in treatment technologies have significantly affected the management of prostate cancer in Japan. This study analyzed the trends in initial treatments for prostate cancer based on two nationwide surveys. METHODS: Two Japan-wide multi-institutional surveys, J-CaP2010 and J-CaP2016, were conducted to enroll patients newly histologically diagnosed with prostate cancer in 2010 and 2016-18, respectively. Both surveys included age at diagnosis, initial PSA level, ISUP Grade Group, TNM classification, and initial treatment for prostate cancer. RESULTS: J-CaP2010 included data from 8192 patients across 140 institutions, whereas J-CaP2016 included data from 21 841 patients across 186 institutions. In J-CaP2016, the proportion of radical prostatectomy (RP) and radiation therapy (RT) in the initial treatment increased (from 32% to 36% and 21% to 26%, respectively), whereas the proportion of ADT decreased (from 40% to 29%) compared with those in J-CaP2010. The increase in RP or RT was noticeable in patients aged 75 years and older (from 20% to 38%) and those with high-risk localized cancer (from 58% to 74%) or locally advanced cancer (from 38% to 56%). The proportion of active surveillance or watchful waiting increased in patients with low-risk localized cancer (from 21% to 41%). The proportion of robot-assisted RP within all RPs and the proportion of intensity-modulated RT within all RTs increased remarkably (from 2.3% to 78% and 20% to 50%, respectively). CONCLUSIONS: In Japan, RP and RT have increased as initial treatments for prostate cancer, whereas ADT has decreased. Consequently, RP has emerged as the most commonly selected initial treatment, replacing ADT.

  　View Summary

  This article is an English translation of the Clinical Practice Guidelines for Upper Tract Urothelial Carcinoma (2nd edition) published in June 2023. The Japanese Urological Association's (JUA) Guidelines Committee on Upper Tract Urothelial Carcinoma (UTUC) created a 2023 update guideline to support clinicians' current evidence-based management of UTUC and to incorporate its recommendations into clinical practice. The new guideline adhered as closely as possible to the Minds Manual for Guideline Development 2020 ver. 3.0. Findings related to epidemiological, pathological, diagnosis, treatment, and follow-up were reviewed. In addition, seven clinical questions (CQs) were set to determine the grade of recommendation and level of evidence. Preconceptions and biases were removed from the preparation process, the overall evidence was evaluated appropriately, and recommendations were made after fully considering the balance between benefits and harms. Although the evidence is still insufficient to be taken up as a CQ, the latest important information is described in seven columns, and clinical issues that should be resolved in the future related to the CQ are described as recommendations for tomorrow. We hope that these guidelines will help medical professionals, patients, and their families involved in the treatment of UTUC in their decision-making, and hope that a critical review of these guidelines will lead to further refinements in the next edition.

  　View Summary

  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. Additionally, we examined the fidelity of strategies to implement the intervention at the provider level in a routine clinical psychiatric setting. METHODS: This was a multicenter, single-arm feasibility study with medical staff at psychiatric hospitals in Japan. The provider-level implementation strategies developed in this study included three key elements (organizing an implementation team appointed by the facility director, interactive assistance using a clear guide that outlines who in the hospital should do what, and developing accessible educational materials) to overcome major barriers to implementation of the intervention and four additional elements (progress monitoring, joint meetings and information sharing among participating sites, adaptation of encouragement methods to specific contexts, and education of on-site staff), with reference to the elements identified in the Expert Recommendations for Implementing Change (ERIC). The feasibility of the strategies was evaluated by the proportion of patients who were eligible for encouragement (patients with schizophrenia aged 40, 50, or 60) who received encouragement. We set the goal of providing encouragement to at least 40% of eligible patients at each site. RESULTS: Two public and four private psychiatric hospitals in Okayama and Shimane prefectures participated in this study. Regarding fidelity, all elements of the strategies were conducted as planned. Following the procedures in the guide, each team prepared and provided encouragement according to their own facility and region. Penetration, defined as the proportion of eligible patients who received encouragement, ranged from 33.3 to 100%; five of the six facilities achieved the target proportion. CONCLUSIONS: The provider-level implementation strategies to implement encouragement were feasible in terms of penetration of the intervention assessed at the patient level. The results support the feasibility of proceeding with a future definitive trial of these strategies. TRIAL REGISTRATION: jRCT, jRCT1060220026 . Registered on 06/04/2022.

  　View Summary

  OBJECTIVES: There is no consensus about the follow-up schedule after 5-year cancer-free periods. In this study, we aimed to elucidate the risk factors for the recurrence in patients with non-muscle-invasive bladder cancer who remained cancer free for more than 5 years. METHODS: Data from six Japanese institutions were retrospectively reviewed. Among the patients with non-muscle-invasive bladder cancer who were treated with transurethral resection of bladder tumor between 1990 and 2013, those who had no recurrence for more than 5 years were included in this study. The Kaplan-Meier method and Cox hazards model were used to estimate recurrence-free survival and to determine the pathologic and clinical factors affecting late recurrence. RESULTS: In total, 434 patients were enrolled in this study. Of these patients, 55 patients (12.7%) experienced late recurrence. The median follow-up time was 8.9 years (interquartile range 6.9-11.3 years). Prior history of bladder cancer before the most recent transurethral resection was a significant predictor for late recurrence (hazard ratio 1.99 [95% confidence interval 1.13-3.47], P = 0.019), although other clinical factors including tumor grade, pathologic stage, tumor multiplicity, and current risk classification systems were not associated with late recurrence. CONCLUSIONS: Late recurrence after a long tumor-free period is not rare and it was not predicted by current risk classification systems. Only prior history of bladder cancer was a significant predictor for late recurrence in this study.

  　View Summary

  In Japan, patients with Hansen‘s disease were forcibly detained, followed by lifetime isolation. To prevent the same mistakes, it is necessary to establish medical ethics for Hansen‘s disease. This project primarily constructed a curriculum on "Hansen‘s disease and Medical Ethics" (for medical students), and on “Hansen‘s disease and Human Dignity” (for elementary to university students), which initiated a series of on-site lectures. Subsequent qualitative analysis of survival narratives elucidated the ethical issues of lost sight due to clinical trials, the structure of spiritual pain from lifelong isolation, perceptual disorders, and their perception of the COVID-19 pandemic. Our published book, "The Beauty of Nature and Prayer in Sanatoriums," and the digital teaching materials, convey the wisdom gained through a life of hardship. Finally, the Society for the Ethics of Hansen‘s disease was established, and the journal “Hansen‘s disease and Human Dignity” was published.

  I developed the system for searching the literature on recurrence of the non-muscle invasive bladder cancer performed in Japan. The database used MEDLINE (PubMed) and a Igaku Chuo Zasshi (Ichushi Web). I developed the software which saves the dounloaded file of PubMed and Ichusi Web with a standardized format. I downloaded the paper which contains "Superficial" in a paper title, and the paper containing "Non-muscle invasive" using this software. And I verified that this software operated normally. Moreover, I prepared the Cloud server for saving these files, and saved data. From now on, I release this technique and will enable use of the developed software.
