I have a case of a colon with two carcinomas, one invasive into the muscularis propria and the other invasive into the submucosa. How do I code them?
T2(m) or T2(2). When there are simultaneous (synchronous) tumours in one organ, the tumour with the highest T category is classified and the multiplicity (m) or number of tumours (2) is indicated in parentheses. If bilateral cancers occur simultaneously in paired organs, each tumour is classified independently. For carcinomas of the thyroid, liver, ovary, and fallopian tube multiplicity is a criterion of T classification. If a new primary cancer is diagnosed within 2 months, the new cancer is considered synchronous (criterion of the SEER Programme of the NCI, USA). 1.
