Professor Masashi Takeuchi's research lab focuses on advancing surgical oncology and clinical decision-making through innovative applications of artificial intelligence and quantitative biomarkers. The lab investigates the role of visceral fat area (VFA) and other imaging-based indicators in predicting postoperative complications and oncological outcomes, particularly in gastrointestinal cancers such as esophageal and gastric cancer. A key direction involves integrating AI into surgical workflows for preoperative planning, intraoperative decision support, and real-time analysis of endoscopic and radiological data. The lab also explores human-like interaction in clinical dialog systems, emphasizing timing and prosody for more natural and effective clinician-patient or clinician-system communication.

High VFA is more useful than BMI in predicting anastomotic leakage and SSI after total gastrectomy. Therefore, we should consider the VFA value during surgery.
Artificial intelligence (AI) has a significant impact on the field of health care, particularly imaging and video analyses. It can considerably support clinical decision-making, including the automatic diagnosis of gastrointestinal cancer during endoscopy and automated detection of pulmonary lesions on computed tomography (CT).1, 2 In the future, AI may provide innovative solutions that improve surgical efficiency and patient outcomes in the field of surgical procedures. Integrating AI into surg
If a dialog system can respond to the user as reasonable as a human, the interaction will become smoother. Timing of response such as backchannels and turn-taking plays important role in such a smooth dialog as in human-human interaction. We are now developing a dialog system which can generate response timing in real time. In this paper, we introduce a response timing generator for such a dialog system. First, we analyzed conversations between two persons and extracted prosodic and linguistic i
Surgical management was conducted adequately through the organized efforts of the entire surgery department in our country even in a pandemic during which medical resources and staff may have been limited.
DCF and subsequent esophagectomy achieved R0 resection in 50% of the patients and was associated with better long-term oncological outcomes in patients with initially unresectable esophageal cancer if their systemic status is acceptable.
