Thirty-five years have passed since the Japanese Society for Cancer of the Colon and Rectum(JSCCR) was first established in 1973. During this period, the incidence of colorectal cancer has increased 4.5 fold in Japan. Consequently, Japan has one of the highest incidences of colorestal cancer in the world. The first edition of the General Rules of Japanese Classification of Colorectal Carcinoma(JCCRC) was published in Japanese in 1977 and the latest edition(7th edition) in 2006. Our classification system and treatment strategy of colorectal cancer differ in some respects from those of western countries; particularly, in grouping and grading of regional lymph nodes, gradiong of lymph node dissection and management of early cancer. Over a period of 35 years, our treatment strategies have undergone substantial development with advances in diagnostic imaging and an accumulation of experience based on analysis of the database of JSCCR, witch has been reflected in each new edition.
In the 7th Japanese edition, considerable changes have been made to enhance consistency both with TNM classification and with Japanese classifications of other gastrointestinal cancers. In addition, the part relating to treatment strategies has been excluded from the 7th edition as the JSCCR guidelines for the treatment of colorectal cancer were published in 2005. All histopathologic micrographs of various types of tumors have been renewed and macroscopic and colonoscopic photographs of tumors of each macroscopic type have been updated in an attempt to help share uniform pictures of the classification of tumor appearances.
As more than 10 years have passed since the first English edition was translated from the 5th Japanese edition, we have decided to publish the English version of the latest edition. The current edition of JCCRC is intended to clarify for foreign clinicians and pathologists the underlying principles of the current Japanese classification system and how they are being continuously developed upon to further improve quality of diagnosis and prognosis of colorectal cancer.
