For cases diagnosed 1998-2003:

Assign extension code 65 for contiguous (direct) extension of tumor from the cervix to the pelvic wall. Assign extension code 85 only if the pelvic wall is involved with discontinuous extension from the cervix; i.e., the cervical tumor spread indirectly (through lymph or vascular channels) to the pelvic wall. Code the pelvic wall involvement in the Extension field and the periaortic lymph node involvement in the Lymph Node field. When the computer does the algorithm, it will look at the periaortic lymph nodes and report the summary stage as distant and the TNM stage group as IV because periarotic nodes are M1. Do not code the periaortic lymph nodes in both fields. This is stage IV, distant disease, due to the periaortic lymph node involvement (EOD lymph nodes code 6).

For tumors diagnosed prior to 2007:

Code as one primary.

For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.

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

This case is reportable if the patient was treated for plasmacytoma. When the physician calls the case plasmacytoma and treats the patient accordingly, report the case.

See Case Reportability Instructions #6: Report the case when there is a clinical diagnosis (physician's statement) of a reportable hematopoietic or lymphoid neoplasm.

Note 1: The clinical diagnosis may be a final diagnosis found within the medical record or recorded on a scan (CT, MRI for example)

Note 2: Report the case even if the diagnostic tests are equivocal. A number of hematopoietic neoplasms are "diagnoses of exclusion" in which the diagnostic tests are equivocal and the physician makes the clinical diagnosis based on the equivocal tests and the clinical picture. See the Heme DB for definitive diagnostic methods for the specific neoplasm being abstracted.

Assign 999 to EOD Primary Tumor if this is the only information you have for your case.The mention of nodules does not automatically mean that you have separate tumor nodules. There are many reasons for the appearance of nodules in the lung, some of which are not due to cancer. Unless you have further information on whether the physician has determined that they are related to the lung cancer, then assume that they are not related.

Assign 00 to EOD Mets. Do not code EOD Mets to 10 since you cannot determine whether those nodules are based on the tumor or not.

If you are able to obtain more information, then you can update the EOD Primary Tumor and EOD Mets.

Regarding the second question, if separate tumor nodules are noted, you cannot assume that they are due to tumor. Further information, or clarification, is needed on whether the separate tumor nodules are related to the lung cancer. Without further information, code EOD Primary Tumor to 999.

There is also some information in the CAnswer Forum since Separate Tumor Nodules are a Site-Specific Data Item: http://cancerbulletin.facs.org/forums/forum/site-specific-data-items-grade-2018/96061-lung-separate-tumor-nodules

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

Code the histology to 9591/3 [B-cell lymphoma, NOS] per Rule PH28 which states that one is to code the histology when the diagnosis is

• specific histology

• specific histologies
• Heme DB Multiple Primaries Calculator documents the specific histologies and NOS are the

There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.

Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.

ASAP is not reportable. Patients with ASAP found on needle biopsy will likely undergo another biopsy.

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.

Use the lung schema to code CS for sarcoma of the lung. Complete the CS information as best you can from the medical record WITHOUT using the TNM Soft Tissue Sarcoma staging form. Visceral sarcomas are specifically excluded from soft tissue sarcoma TNM staging and sarcomas are excluded from the TNM staging for lung.

Sarcoma is listed on the Histology Exclusion Table for lung. When a case is coded in Collaborative Staging and the histology is on the exclusion list, SEER Summary Stage 1977 and 2000 can be assigned. For these cases, TNM will not be calculated and displayed results will be "T NA N NA M NA and Stage Group NA".

Pseudotumor cerebri is not reportable. It is not a neoplasm. The pressure inside the skull is increased and the brain is affected in a way that appears to be a tumor, but it is not a tumor.

For cases diagnosed prior to 1/1/2010:Primary site:

Code the primary site to C421 [bone marrow] per primary site coding instructions for leukemia in the 2007 SEER manual, page 70.

Surgery of other site:

Since all surgical procedures for hematopoietic diseases are coded in the data item Surgery of Other Site, assign code 1 [Nonprimary surgical procedure performed].

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.
