[A report of five cancer screening rates and the related measures for cancer control in the workplace, surveyed by the Corporate Action to Promote Cancer Control].

Objectives: Most cancer control measures in the workplace have limited supporting evidence. This study aimed to identify highly effective cancer control measures, based on a survey by the Corporate Action to Promote Cancer Control.

Methods: The firms and organizations that responded to the web survey were included.

Medical costs according to the stages of colorectal cancer: an analysis of health insurance claims in Hachioji, Japan.

Background: Although the effect of the early detection of colorectal cancer (CRC) on medical costs needs to be clarified, there are few reports on the actual medical costs of CRC patients in Japan. We aimed to identify medical costs according to CRC stage, using health insurance claims.

Methods: This observational study included CRC patients who had received specific treatment for CRC, which was defined by the procedure code and the claim computer processing system code associated with the treatment of CRC.

Increasing hepatitis virus screening uptake at worksites in Japan using nudge theory and full subsidies.

Background: Despite the importance of hepatitis screening for decreasing liver cancer mortality, screening rates remain low in Japan. Previous studies show that full subsidies increase screening uptake, but full subsidies are costly and difficult to implement in low-resource settings. Alternatively, applying nudge theory to the message design could increase screening at lower costs.

Recommendations from primary care physicians, family, friends and work colleagues influence patients' decisions related to hepatitis screening, medical examinations and antiviral treatment.

Identification and screening of patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) is important to prevent liver cancer. Comprehensive antiviral treatments should follow three sequential steps: Hepatitis screening (step 1; examination of HB surface antigen and HCV antibody), medical examination (step 2; examination of HBV-DNA and/or HCV-RNA and performance of abdominal ultrasonography) and antiviral treatment (step 3). Patients who underwent these three steps were studied to determine effective information sources (factors) for raising awareness of comprehensive treatments.

Cancer Prevention Using Machine Learning, Nudge Theory and Social Impact Bond.

There have been prior attempts to utilize machine learning to address issues in the medical field, particularly in diagnoses using medical images and developing therapeutic regimens. However, few cases have demonstrated the usefulness of machine learning for enhancing health consciousness of patients or the public in general, which is necessary to cause behavioral changes. This paper describes a novel case wherein the uptake rate for colorectal cancer examinations has significantly increased due to the application of machine learning and nudge theory.

Tailored message interventions versus typical messages for increasing participation in colorectal cancer screening among a non-adherent population: A randomized controlled trial.

Background: The purpose of this study was to examine the effectiveness and cost-efficiency of a tailored message intervention compared with a non-tailored message intervention for increasing colorectal cancer (CRC) screening rates among a non-adherent population, in a community-based client reminder program.

Methods: After a baseline survey for psychological segmentation, 2140 eligible individuals were randomly assigned either to a group with a tailored matched-message condition (N = 356), a group with a non-tailored unmatched-message condition (N = 355), or to two control groups, one using a typical message with a professional design (N = 717) and one without a professional design (N = 712). The main outcome measure was attendance rates in a community-organized CRC screening program within five months of receiving a print reminder.

Evaluation of a free-coupon program for cervical cancer screening among the young: a nationally funded program conducted by a local government in Japan.

Background: Finding ways to improve the cervical cancer screening rates among young women has been seen as a critical national health problem in many countries, including Japan. The aim of the present study was to evaluate the effects of a free-coupon program for cervical cancer screening conducted by a local government under financial support from the Japanese national government.

Methods: The personal cervical cancer screening information was analyzed for all female residents of Toyonaka City, including any past screening history and clinical results since the year 2009, when a free-coupon program for screening was started.

Worry and intention among Japanese women: implications for an audience segmentation strategy to promote mammography adoption.

We examined the predictive validity of a segmentation strategy based on intention and cancer worry for mammography adoption and explored key factors for promoting mammography adoption in each segment. A questionnaire survey was completed by 641 women aged 40-59 years. Among them, 559 answered a follow-up survey after 15 months.

Cost-effectiveness of a tailored intervention designed to increase breast cancer screening among a non-adherent population: a randomized controlled trial.

Background: Although the percentage of women who initiate breast cancer screening is rising, the rate of continued adherence is poor. The purpose of this study was to examine the effectiveness and cost-effectiveness of a tailored print intervention compared with a non-tailored print intervention for increasing the breast cancer screening rate among a non-adherent population.

Methods: In total, 1859 participants aged 51-59 years (except those aged 55 years) were recruited from a Japanese urban community setting.
