For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

The PH rules for coding lymphomas (Module 7) refer to a lymph node region as defined by the ICD-O-3. Per the Appendix C, , the ICD-O-3 lymph node region for "pelvic" is C775. In this case, there is one lymph node region involved (bilaterally). Per Rule PH20, code the specific lymph node region when multiple lymph nodes within the same lymph node region (as defined by the ICD-O-3) are involved, C775. Per Note 1 under Rule PH20, use this rule when there is bilateral involvement of lymph nodes.

This same table in Appendix C also provides information on how left and right pelvic lymph nodes are categorized by AJCC for purposes of coding stage. If the left and right pelvic lymph nodes are positive for lymphoma, it is involvement of two regions. The case is coded as Stage II.

Keep in mind that the ICD-O-3 definition of regions is used to code the primary site, while the AJCC definition of regions is used to code stage.

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

Any treatment that destroys or modifies cancer tissue should be recorded as the appropriate type of treatment -- chemo, immuno, etc. Even if immunotherapy is given for symptoms/palliative treatment, it is likely to kill off tumor cells.

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Lymph nodes with metastases greater than 0.2 mm are counted as positive. Code in CS Lymph Nodes and CS Regional LN Positive. Do not code ITC's greater than 0.2 mm in CS Site Specific Factor 4.

For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.

Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.

Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants.
