New Histopathological Diagnostic Terms and their Codes of the Central Nervous System (CNS) in the International Classification of Diseases for Oncology (ICD-O 3.1) and about the Turkish Version of ICD-O

M. Serefittin Canda

International Classification of Diseases for Oncology (ICD-O), which has been used in the world since 1976 for 40 years and has been translated into many languages, emphasizing the importance of health and cancer is presented. In addition, the histopathological classification working group of central nervous system (CNS) tumors has proposed new terms and their new ICD-O codes, taking into account their genetic characteristics. Our goal is to emphasize the current importance of ICD-O. Since 2015, ICD-O has been put into practice by the Ministry of Health in Turkey. Writing of ICD-O codes is required for pathology reports. In the last 25 years, I have translated the ICD-O three times into Turkish, 1992, 2002 and 2015, serving as pathology, oncology, cancer registrars and the Ministry of Health.
