Date Therapy Initiated/Reason no treatment--Lymphoma: Is the date of the lymph node biopsy used as the date of treatment if the lymph node biopsy is the first treatment or the only treatment performed? Is the reason for no surgery coded to 0 [Surgery of the primary site was performed]?
For cases diagnosed prior to January 1, 2008, enter the date of the lymph node biopsy (excisional biopsy or biopsy NOS) as the Date Therapy Initiated for a lymphoma when the biopsy is the first or only therapy performed.
Code Reason for No Surgery of Primary Site as 0 [Surgery of the primary site was performed] and the biopsy of a lymph node is coded to 25 in Surgery to Primary Site.
Do not code a fine needle aspiration or core needle biopsy in Surgery of Primary Site.
CS Tumor Size/CS Extension--Brain and CNS: How are these fields coded for a glioblastoma multiforme occurring in a 3.5 cm tumor in the parietal lobe and a 3.0 cm tumor in the occipital lobe?
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.
CS Extension code is 10 [confined to cerebral hemisphere]. Record the size of the largest lesion in CS Tumor Size. Both the occipital and parietal lobes are supratentorial and confined to the cerebral hemisphere with no mention of crossing midline or involvement of ventricles.
Histology (Pre-2007): Is histology for an anorectal biopsy of "Cloacogenic carcinoma (squamous cell carcinoma with basaloid features)" coded to 8124/3 [Cloacogenic carcinoma] or 8083/3 [Basaloid squamous cell carcinoma]?
For tumors diagnosed prior to 2007:
Code histology to 8124/3 [Cloacogenic carcinoma]. These are squamous cell carcinomas of basaloid type that are found in the cloacogenic (transitional) zone of the anal canal.
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.
Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma?
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.

Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML?
If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS).
MP/H Rules--Ovary: Rule M7 states bilateral epithelial tumors (8000-8799) are reportable as a single primary. Are bilateral germ cell tumors of the ovary (e.g., dysgerminoma (9060/3)) that occur simultaneously now reported as two primaries?
For cases diagnosed 2007 or later, rule M7 applies to ovarian epithelial tumors with ICD-O-3 histology codes between 8000 and 8799. Rule M7 does not apply to dysgerminoma which is coded to 9060. Go on to the next rule, M8 and abstract as multiple primaries, left and right.
Surgery of Primary Site--Breast: Should code 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) be used when a patient has excisional biopsy (22) and axillary dissection followed by a simple mastectomy without removal of uninvolved contralateral breast (41) as part of the first course of treatment?
Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case.
SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site.
Extension/CS Extension--Prostate: Do the prostate guidelines used for EOD still apply to cases diagnosed 2004 forward?
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.For cases diagnosed 2004 and forward, refer to the Collaborative Staging manual.
The 2004 CS guidelines have been agreed upon by all standard setters and have been reviewed by the COC/AJCC urologists.
Note: Do not use the SEER EOD guidelines with Collaborative Staging.
Primary site--Heme & Lymphoid Neoplasms: What is the primary site for a bone marrow biopsy positive for systemic mastocytosis that also involves the spleen and lymph nodes with associated leukocytosis, mild anemia and thrombocytopenia?
Per Rule PH30, one is to use the to determine the primary site and histology when rules PH1-PH29 do apply. Code the primary site to C421 [bone marrow] because that is the only site listed under the Primary Site section of the Heme DB.
Under the Abstractor Notes section in the Heme DB, it indicates that the bone marrow is always involved, and the white and red pulp of the spleen may be involved with systemic mastocytosis. This is how this patient presented; therefore, the bone marrow is the primary site. The spleen is secondarily involved because the spleen cleanses the blood and the neoplastic cells have infiltrated the red and white pulp of the spleen. The same is true for the lymph nodes. Although the lymph nodes are rarely involved, they may be involved when the patient has systemic mastocytosis.

EOD-Extension--Head & Neck (Uvula): Is a stage T2 tumor described on the physical exam as an "ulcerated mass occupying uvula midline soft palate, and extending into the right soft palate. It does not extend into the tonsil area nor into the retromolar trigone" coded to 30 [localized, NOS] or 40 [tumor crosses midline]?
For cases diagnosed 1998-2003:
Code EOD-extension to 30 [localized, NOS]. This is mucosal spread (since there is no muscle in the uvula). Soft palate and uvula are handled as a single site, and extension from uvula to soft palate is not addressed in EOD.
