Colorectal Cancer Study Group

What Colorectal Cancer Study Group does

The Japanese Society for Cancer of the Colon and Rectum (JSCCR / 大腸癌研究会) is a private nonprofit academic medical society founded in 1977 and headquartered in Chiyoda-ku, Tokyo. JSCCR serves as Japan's central coordinating body for colorectal cancer research, serving hundreds of member hospitals, universities, individual clinicians, and supporting corporate members. Its core deliverables are clinical practice guidelines (colorectal cancer treatment, hereditary colorectal cancer, IBD-associated gastrointestinal neoplasia), the Japanese Classification of Colorectal Carcinoma (大腸癌取扱い規約, currently 9th edition, 2018), and the National Colorectal Cancer Registration (全国大腸癌登録), which has accumulated treatment data since 1974.

Underlying assets include a longitudinal multi-institutional registry spanning decades, standardized TNM-aligned classification systems, pathological atlases, and web-based nomogram tools for postoperative prognosis prediction. The society operates through project research groups, committees (guideline, chemotherapy, COI), annual scientific conferences (currently the 104th and 105th meetings), and an annual Excellent Paper Award program. Distribution occurs through the official website (jsccr.jp), the designated publisher Kanehara Shuppan, Amazon Kindle for patient guidelines, and partnerships with adjacent societies such as the Japan Society of Gynecologic Oncology and Japan Society of Hepato-Biliary-Pancreatic Surgery.

Revenue is generated primarily through recurring institutional membership dues (20,000 yen/year per facility, 3,000 yen for individual associates, minimum 100,000 yen for supporting corporate members), supplemented by publication sales and conference-related income. JSCCR's English-language guidelines are published in the International Journal of Clinical Oncology, supporting its international visibility beyond the domestic Japanese market.
