Groundbreaking Research on Wearable Data Utilization

Tech Doctor, a leading company in healthcare innovation based in Tokyo, recently collaborated with ExaWizards and the Kansai Medical University to present significant findings at the American Society of Clinical Oncology (ASCO) 2026 Annual Meeting. During this major oncology event, which is one of the largest of its kind globally, the results of a study focused on early breast cancer patients utilizing wearable technology were showcased in a poster presentation.

Research Overview

This innovative study was a prospective observational research project aimed at early breast cancer patients undergoing preoperative chemotherapy. The research utilized data acquired from Google Fitbit devices—which monitored daily physical activity, sleep patterns, and heart rate—alongside electronic patient-reported outcomes (ePRO). The continuous collection of this data during everyday life allowed the team to analyze the relationships between patients' health metrics and their reported experiences throughout the treatment process.

Study Title and Leadership

The study is officially titled "Use of Wearable Devices to Assess Activity Levels in Early Breast Cancer Patients Preparing for Preoperative Chemotherapy (TRACK-BC)." It was led by Dr. Yuichiro Kikawa, a clinical professor in the Breast Surgery Department at Kansai Medical University. Co-author Dr. Nobuhiro Shibata, a clinical lecturer from the Medical Oncology Department of Kansai Medical University, was also instrumental in the study.

Tech Doctor’s Role

Tech Doctor played a crucial role in this research by providing the infrastructure necessary to collect wearable data and ePROs effectively. The company also supported data management, exploratory data analysis, and the implementation of machine learning techniques to enhance the quality of the insights derived from the data.

Importance and Future Prospects

As cancer treatments increasingly take place on an outpatient basis, maintaining an accurate understanding of patient conditions in their daily lives has become vital. This innovative approach to collecting data using wearable devices and ePRO emphasizes the growing interest in capturing objective health metrics to aid in medical research and clinical practice. Such methodologies represent a promising new avenue for understanding patient health holistically.

With the ongoing collaboration between Tech Doctor and various medical and research institutions, the aim is to further harness wearable data to foster advancements in healthcare solutions. As we progress, more detailed analyses and findings from this research will be shared through academic presentations and publications in the future.

Conference Presentation Details

The ASCO 2026 Annual Meeting will take place from May 29 to June 2, 2026, featuring both in-person and online presentations at McCormick Place in Chicago, IL. The emphasis on fostering collaboration among medical scientists and practitioners at this prestigious conference highlights its significance in advancing oncology research.
