Note 2: The assignment of T1 and T2 categories for soft tissue sarcomas is based on tumor size. A physician's statement of the T category may be used to code CS Tumor Size and/or CS Extension if this is the only information in the medical record regarding one or both of these fields. However the two fields are coded independently: for example the record may document size but not extension, other than the physician's statement of the T category. Use codes 350 and 375 as appropriate to code CS Extension based on a statement of T when no other extension information is available.

Distant nodes are coded in CS Mets at DX. Note 2: Regional lymph nodes are defined as those in the vicinity of the primary tumor. Note 3: Regional lymph node involvement is rare. For this schema, if there is no mention of lymph node involvement clinically, assume that lymph nodes are negative. Use code 999 (Unknown) only when there is no available information on the extent of the patient's disease, for example when a lab-only case is abstracted from a biopsy report and no clinical history is available.
