Anatomic Pathology

What we do

The Department of Clinical Pathology at Kameda Medical Center provides the "definitive final diagnosis" for tissue specimens, cytological samples, and resected surgical organs submitted across all clinical departments. We also perform real-time intraoperative frozen section consultations to determine tumor margins and diagnosis during active surgeries.

Although pathologists rarely meet patients in person, almost all cancer care and complex clinical management plans at Kameda Medical Center are built upon our pathological diagnoses—making our department the vital backbone of the medical center's clinical quality.

Pioneering Innovations & World-First Initiatives

Our center is globally recognized for pioneering advanced, collaborative pathology workflows:

1. World-First Virtual Consensus & Collaborative "Sign-Out Sessions":
To eliminate individual diagnostic errors in high-stakes pathology, we introduced a multi-pathologist "Sign-Out Session" system. Utilizing state-of-the-art digital pathology, we maintain a real-time virtual diagnostic space connecting our team with:

Kameda Kyobashi Clinic (Radiology-Pathology Department, Tokyo)
Nagasaki University (Department of Pathology Diagnostic Medicine)

This world-first system enables instant subspecialty consultation and expert consensus, attracting medical observers from across Japan and around the globe. Weekly inter-institutional academic conferences and genomic medicine boards ensure our diagnostic standards remain cutting-edge.

2. Radiology-Pathology (RP) Diagnostic Fusion & Academic Training:
At Kameda Kyobashi Clinic, we established a novel Radiology-Pathology Department where pathologists and radiologists jointly review routine microscopic slides alongside cross-sectional imaging (RP Conferences) to issue unified consensus diagnoses. Backed by a team of 25 dedicated pathologists, an extraordinary scale for a private hospital, we offer an academic training environment equivalent to major university hospitals.

3. Advanced Artificial Intelligence (AI) Integration:

We actively integrate Artificial Intelligence (AI) into our diagnostic workflow to enhance efficiency and precision. In genomic medicine and molecular biomarker testing, AI algorithms assist our pathologists in accurately quantifying tumor cellularity and lesion density.

Academic Societies & Global Affiliations

Our pathology team actively contributes to leading national and international medical societies:

Japanese Society of Pathology (JSP)
Japanese Society of Clinical Cytology (JSCC)
Japan Lung Cancer Society / Japanese Respiratory Society
Japanese Breast Cancer Society / Japan Cancer Association
Japanese Society for Infectious Diseases
Japanese Society of Digital Pathology
