Cervical cancer screening efficacy using SurePath, ThinPrep and conventional cytology: A large data set analysis from the Japan Cancer Society.

Objective: Over the past decade, liquid-based cytology has replaced conventional cytology for cervical cancer screening in many countries, including Japan. We aimed to evaluate the efficacy of liquid-based cytology using a large database and compare two major liquid-based cytology platforms, SurePath and ThinPrep, to conventional cytology.

Methods: Cervical cancer screening data were collected from the Japan Cancer Society between 2015 and 2019.

The consecutive impact of COVID-19 on thoracic surgical procedures in Japan: an analysis of data from the National Clinical Database.

Purpose: The current study was designed to analyze the impact of the COVID-19 pandemic on general thoracic surgeries in Japan.

Methods: Changes in surgeries for lung cancer and metastatic lung tumors were evaluated based on National Clinical Database data regarding cancer screening.

Results: In 2021, surgeries for primary lung cancer increased by 3.

Impact of coronavirus disease 2019 on the number of newly diagnosed cancer patients and examinations and surgeries performed for cancer in Japan: a nationwide study.

Background: The coronavirus disease 2019 (COVID-19) pandemic has rapidly and dramatically influenced healthcare across Japan. However, the influence of the COVID-19 pandemic on the number of newly diagnosed cancer, surgical treatment, and diagnostic examination for cancer types have not been completely investigated all over Japan. This study aimed to analyze the number of cases before and during the COVID-19 pandemic.

The impact of COVID-19 on thoracic surgical procedures in Japan: Analysis of data from the National Clinical Database.

Objective: The COVID-19 pandemic has far-reaching collateral health impacts on the ongoing delivery of surgical care worldwide. The current study was designed to analyze the impact of the COVID-19 pandemic on the number of surgeries of general thoracic surgery in Japan.

Methods: Changes in the number of surgeries for total and three representative tumors were analyzed using the National Clinical Database data with reference to the pandemic infection rate and lung cancer screening.

Patient-reported outcomes following neoadjuvant endocrine therapy, external beam radiation, and adjuvant continuous/intermittent endocrine therapy for locally advanced prostate cancer: A randomized phase III trial.

Background: We evaluated patient-reported outcomes (PRO) during neoadjuvant androgen deprivation therapy (ADT) plus external beam radiation therapy (EBRT) followed by either adjuvant continuous ADT (CADT) or intermittent ADT (IADT) for patients with locally advanced prostate cancer (Pca).

Methods: A multicenter, randomized phase III trial enrolled 303 patients with locally advanced Pca. The patients were treated with 6 months (M) of ADT followed by 72 Gy of EBRT, and were randomly assigned to CADT or IADT after 14 M.

Effectiveness of HPV vaccination against the development of high-grade cervical lesions in young Japanese women.

Background: Although more than 10 years have passed since HPV vaccination was implemented, first as an interim programme (Emergent vaccine promotion programme) in November 2010, followed by incorporating into the National Immunization Programme in April, 2013 and suspended in June 2013, limited studies have investigated the HPV vaccine effectiveness against high-grade cervical lesions in Japan.

Methods: We collected the matched data of the results of cervical biopsy and history of vaccination from the Japan Cancer Society database. The subjects were women aged 20 to 29 years screened for cervical cancer between April, 2015 and March, 2017, and with information on HPV vaccination status.

Human papillomavirus vaccine to prevent cervical intraepithelial neoplasia in Japan: A nationwide case-control study.

Cervical cancer remains among the most common cancers in women worldwide and can be prevented by vaccination. The Ministry of Health, Labour and Welfare of Japan suspended active recommendation of regular human papillomavirus (HPV) vaccines in 2013 because of various symptoms including chronic pain and motor impairment. This nationwide case-control study from April 2013 to March 2017 targeted women aged 20-24 years old at cervical screening.

Orthotopic neobladder after cystectomy for bladder cancer.

More than 90% of bladder cancer is composed of transitional cell carcinoma (TCC), being characterized by the development of multiple tumors in the entire urinary tract over time. When cystectomy is conducted, the urinary tract must be reconstructed by various procedures, which can include an orthotopic neobladder using the patient's own intestine formed into a spherical shape anastomosed to the urethra. Using this procedure, patients can void urine from their own urethra even after cystectomy.

Impact of reduced smoking rates on lung cancer screening programs in Japan.

Background: In Japan, lung cancer screening by annual chest radiography has been performed for the past 30 years. However, changes in risk factor status may have influenced the efficiency of current organized lung cancer screening program. The purpose of this study was to clarify whether the reduced smoking rate in younger Japanese affects the efficiency and effectiveness of lung cancer screening.

Oncological outcomes for patients with locally advanced prostate cancer treated with neoadjuvant endocrine and external-beam radiation therapy followed by adjuvant continuous/intermittent endocrine therapy in an open-label, randomized, phase 3 trial.

Background: To date, research has not determined the optimal procedure for adjuvant androgen deprivation therapy (ADT) in patients with locally advanced prostate cancer (PCa) treated for 6 months with neoadjuvant ADT and external-beam radiation therapy (EBRT).

Methods: A multicenter, randomized, phase 3 trial enrolled 303 patients with locally advanced PCa between 2001 and 2006. Participants were treated with neoadjuvant ADT for 6 months.

Effectiveness of HPV vaccination against high grade cervical lesions in Japan.

The effectiveness of HPV vaccine against HSIL+ (pathologically diagnosed CIN2+) in the first cohort in Japan was investigated in 22,743 women aged 20 to 29 years (parts of national cervical cancer screening program of FY [fiscal year] 2015, the Japan Cancer Society). Vaccinated women had a statistically significant 69% lower risk of HSIL+ as compared to the unvaccinated women; the crude relative risk estimate was 0.31 (95% CI: 0.

Genomic Landscape of Experimental Bladder Cancer in Rodents and Its Application to Human Bladder Cancer: Gene Amplification and Potential Overexpression of Cyp2a5/CYP2A6 Are Associated with the Invasive Phenotype.

Non-muscle invasive (superficial) bladder cancer is a low-grade malignancy with good prognosis, while muscle invasive (invasive) bladder cancer is a high-grade malignancy with poor prognosis. N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) induces superficial bladder cancers with papillary morphology in rats and invasive bladder cancers with infiltrating phenotype in mice. In this study, we analyzed genomic landscapes of rodent BBN-induced bladder cancers using array-based comparative genomic hybridization (array CGH).

[Ten Years after Implementation of Cancer Control Act].

A brief description of the history of Cancer Control in Japan was presented for the first time. The establishment of the National Cancer Center and Comprehensive 10-year Strategy for Cancer Control Program, which has been implemented for 30 years, is most important. In response to the concerns raised by cancer patients, their families, and lay people, such as elimination of disparity arising from where they live or which hospital they attend, and asymmetrical cancer information, the Cancer Control Act was established in 2006 and executed in 2007.

[Cancer Education from Childhood].

Cancer education from childhood should include important issues such as lifestyle and time-determined human life. It should be established as a continuing education targeting not only junior and senior high school but also elementary school students. A compassionate newmovement is desirable between children and their parents concerning lifestyle, including tobacco use and cancer screening.

[Cancer screening in Japan and prostate cancer screening].

National cancer control programs are structured to include four main areas: prevention, screening, diagnosis and treatment, and palliative care. Cancer screening is particularly important because it helps to reduce medical costs and achieve maximum benefits for both patients and the country. There are many issues with cancer screening in Japan that need a solution, such as low participation rate and lack of sufficient quality control.
