Collaborative Stage Data Set - Revised 11/11/2010 FINAL

Lymphoma

CS Extension

Note 1: An E lesion is defined as disease that involves extralymphatic site(s), or sites other than lymph nodes and other lymphatic structures. Other lymphatic structures include spleen (see note 4), thymus gland (C37.9), and Waldeyer's ring (tonsils) (C02.4, C09.0-C09.9, C11.1, C14.2),. Any lymphatic structure (other than spleen) is coded the same as a lymph node region (codes 100, 200, 300).
Note 2: While spleen is considered a lymphatic structure, it is coded separately (see codes 120, 220, 230, 320, 330). S equals spleen involvement.
Note 3: If there is no mention of lymphatic or extralymphatic involvement but several diagnostic procedures were done, interpret as no involvement.
Note 4: Involvement of adjacent soft tissue does not alter the classification.

330	320 + 310 Involvement of the spleen PLUS a single extralymphatic site ABOVE the diaphragm WITH or WITHOUT involvement of lymph node(s) Involvement of the spleen PLUS involvement of lymph node region(s) ABOVE the diaphragm PLUS involvement of a single extralymphatic organ/site on either side of the diaphragm Stated as Stage IIIES	^	*	D	D
800	Diffuse or disseminated (multifocal) involvement of ONE OR MORE extralymphatic organ(s)/site(s) WITH OR WITHOUT associated lymph node involvement Multifocal involvement of MORE THAN ONE extralymphatic organ/site Involvement of isolated extralymphatic organ in absence of involvement of adjacent lymph nodes, but in conjunction with disease in distant sites Metastasis/involvement: Bone marrow Liver Nodular involvement of lung(s) Stated as Stage IV	^	*	D	D

^ AJCC stage group for this schema is derived directly from CS Extension and CS Site-Specific Factor 2, as shown in the AJCC TNM 7 Stage table. The AJCC Stage Groups I-IV are subdivided into A and B based on the presence or absence of symptoms coded in CS Site-Specific Factor 2.
* AJCC stage group for this schema is derived directly from CS Extension and CS Site-Specific Factor 2, as shown in the AJCC TNM 6 Stage table. The AJCC Stage Groups I-IV are subdivided into A and B based on the presence or absence of symptoms as coded in CS Site-Specific Factor 2.
