Behavior--Breast: How is behavior coded when a biopsy shows in situ carcinoma with a focus suspicious for invasion and a subsequent excision/resection shows only in situ carcinoma?
Code this case as in situ. The specimen from the excision/resection is the more reliable source for determining behavior, compared to a biopsy, especially in this case where the behavior is ambiguous on the biopsy.
MP/H Rules/Histology--Lung: How is histology coded for a diagnosis of squamous carcinoma and large cell undifferentiated neuroendocrine carcinoma?
For cases diagnosed 2007 or later, apply rule H7 and code the numerically higher ICD-O-3 code, 8070/3 [Squamous cell carcinoma]. See Chart 1, the histology tree in lung equivalent terms. Large cell neuroendocrine carcinoma is histology code 8013/3. The other histology is squamous carcinoma, 8070/3. 8070/3 is higher numerically than 8013/3.
Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia)
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information.
CS Site Specific Factor 6--Breast: Can we interpret the in situ component as "minimal" when the pathology report states "1.1 cm infiltrating duct carcinoma and no extensive intraductal component"?
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.
Yes. Based on the information provided above, the in situ component is "mininmal" for the purpose of coding Breast CS Site Specific Factor 6. The phrase "no extensive intraductal component" suggests that there is some intraductal carcinoma present.
CS Eval--All Sites: If any of the CS fields (TS/Extension, LN, or Mets) are based on the TNM and there is no text documenting the basis for the evaluation, are the evaluation fields coded to 0 instead of 1?
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.
Assign code 0 [No surgical resection done...based on physical exam...or other non-invasive clinical evidence] to the corresponding eval fields when CS Extension, Lymph Nodes or Mets at Diagnosis are coded based only on the TNM and no further information is available.
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.
Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed with small lymphocytic lymphoma in 1996, received chemotherapy on and off for 15 years due to relapses, and was subsequently diagnosed with diffuse large B-cell lymphoma in 2012?
Per Rule M10, this case should be accessioned as two primaries. According to Rule M10, one is to abstract as multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm AND there is a second diagnosis of an acute neoplasm more than 21 days after the chronic diagnosis.
The histology for the 1996 chronic neoplasm is coded to 9670/3 [small lymphocytic lymphoma]. The histology for the 2012 acute neoplasm is 9680/3 [diffuse large B-cell lymphoma].

Code histology to 9732/3 [multiple myeloma]. The plasmablastic subtype/variant does have a prognostic indication, but the disease is still coded as multiple myeloma.

No. Per Appendix F, erythrocytosis of an unknown cause is not reportable.
The diagnosis must state "erythrocytosis megalosplenic" to be reportable (9950/3).

CS Extension/CS Mets at Dx--Corpus uteri: Is a microscopic metastasis in a cul-de-sac implant more appropriately reflected in the CS Extension field code 80 [Further contiguous extension; cul-de-sac] or in the CS Mets at Dx field code 40 [Distant metastasis]?
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.Assign code 80 [Further contiguous extension; Cul de sac] for CS extension in this case. Endometrium and ovary are exceptions to the rules that only contiguous extension is coded in Extension code 80. Only true distant metastases are coded in Mets at Dx.
