Introduction

 In order to promote the best cancer treatment, which is our hospital's philosophy, the Department of Clinical Laboratory is committed to "providing the best cancer treatment," "research, development and dissemination of new medical care," and "supporting Japan's efforts through education and training." We carry out activities to improve medical care and disseminate information domestically and internationally. We provide the best clinical tests for patients at the Hospital East through three pillars: medical support, research, and education.

The Team and What We Do

 The total number of clinical tests in FY2023 was 4,730,290, an increase of approximately 3.9% from the previous year, and it is increasing year by year (Table 1).

 The number of clinical trial tests was 97% for sample processing (PK), 121% for electrocardiogram tests, and 90% for pathology specimen preparation compared to the previous year (Table 2).

 In August 2022, the facility obtained CAP accreditation (College of American Pathologists).

 By obtaining CAP accreditation, the facility's clinical test data can be statistically compared with laboratories around the world, and by recognizing the internationally mainstream testing methods, the facility provides more accurate test data.

Research Activities

 Active introduction of LBC (Liquid-based cytology)

 The introduction of LBC has resulted in shorter screening times, improved cell collection rates, and reduced technical errors. The introduction of LBC has reduced the number of cases determined to be false positives (513 false positives out of 5,868 cases in FY2023).

Education

 We actively support employees in obtaining certified qualifications to improve their academic knowledge and skills.

 In 2023, one ultrasound technician and two certified pathology technicians passed the exams.

 Since October 2022, one employee has been job-rotated to the Department of Medical Information to gain experience in another field. This has produced positive results, as the system can now be built smoothly within the testing department and network problems can be handled smoothly.

 Five clinical technician trainees have been accepted from four facilities.

Future Prospects

 As a clinical testing facility that has acquired the international standard ISO15189 certification and CAP accreditation (College of American Pathologists), the facility provides support for medical treatment and clinical research at the Hospital East. In the future, the facility will strengthen collaboration with other departments at the Hospital East and the Exploratory Oncology Research & Clinical Trial Center, and build a system that will enable it to participate in the development of self-regulated tests (LDTs). The facility will contribute to the realization of Hospital East's vision of "providing the world's best cancer medical care and creating new world-class cancer medical care."
