Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when bilateral breasts are involved with MALT lymphoma and the bone marrow is negative?
Per Rule M2, this is a single primary because there is a single histology mentioned. The histology is coded to 9699/3 [MALT lymphoma]. Code the primary site to C509 [breast] per Rule PH24 which states to code the primary site to the organ when lymphoma is present only in an organ.
Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal, extragastric MALT lymphomas occur in multiple sites, particularly in paired sites (breast is an example).
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.
MP/H Rules/Histology--Lung: What would the histology code be for a wedge bx of the left lung, lower lobe, that was read out as well differentiated adenocarcinoma with micropapillary features?
Code papillary adenocarcinoma 8260/3. The ICD-O-3 codes for micropapillary have specific associations such as ductal, serous or transitional. None of those associations fit lung primaries.
SEER*RSA/Required data items--Melanoma: The site-specific data item, Ulceration, states it is required by "All" in SEER*RSA but in the NAACCR Data Dictionary table it states is it required by SEER, Commission on Cancer (CoC), and Canadian Cancer Registry (CCCR), not the National Program of Cancer Registries (NPCR). Does the definition of "All" in SEER*RSA not include NPCR? Also, please explain the difference between Required by: "All" and "Required by CCCR/Canada, COC, NPCR, SEER" (all listed out).
Use the NAACCR Data Dictionary Required Status Table or refer to standard setter requirements. Do not use SEER*RSA to determine which data items are required to be collected or transmitted. Though "All" in SEER*RSA generally refers to the standard setters including CoC, NPCR, CCCR, and SEER, some items in SEER*RSA need updating; this is planned for 2022.
Primary site--Kidney, renal pelvis: Should primary site be coded C809 [unknown] or C649 [kidney] when a patient is diagnosed with renal cell carcinoma in a transplanted kidney?
Code the primary site to C649 [kidney]. Per the SEER Manual, code the site where the neoplasm originated. There are no separate instructions for coding primary site for transplanted organs. This patient's renal cell carcinoma originated in the kidney [C649].
Surgery of Primary Site--Bladder: Do we code "random bladder biopsies" as an excisional biopsy (27) or as no cancer directed surgery (00) even if the only involvement mentioned on the pathology reports is "focal carcinoma in situ"?
Code the Surgery of Primary Site field to 00 [None; no surgery of primary site] when only random biopsy procedures are performed on the bladder.
Radiation Therapy--Breast: If hospital records indicate that a mammocyte intracavitary radiation therapy device was placed in the breast, but there is no follow-up documentation of radiation actually being given, should we code radiation 2 (implants) or 8 (recommended, unknown if given)?
Assign code 8 [recommended, unknown if administered]. Check this case periodically, and others coded 8. Update if further information becomes available.
Surgery of Primary Site--Breast: How is this field coded for cryosurgery of the breast?
For cases diagnosed 2003 and later: For cryosurgery alone, without a pathology specimen, assign site-specific surgery code 19 [Local tumor destruction, NOS]. Cryosurgery, cryotherapy or cryoablation uses extreme cold to destroy the tumor cells.
If a specimen is sent to pathology use code 20 [Partial mastectomy, NOS] rather than code 19.
If cryosurgery is followed by further surgery, do not use code 19.
Reportability--Hematopoietic, NOS: Is a "refractory cytopenia with excess blasts" discovered on a bone marrow biopsy reportable?
For cases diagnosed prior to 1/1/2010:
Refractory cytopenia with excess blasts (RCEB) is reportable. RCEB is the same disease process as refractory anemia with excess blasts, except there is more than one type of blood cell that is low (red, white, platelets).
For cases diagnosed 2010 forward, 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.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: For cases diagnosed in 2005, if a specimen contains an invasive 4.5 cm lobular carcinoma of the right breast and also has a tiny focus of intraepidermal tumors cells [Paget disease of nipple], how many cases should be abstracted and how should the histology field(s) be coded?
For tumors diagnosed prior to 2007:
There are two primaries in this example:
1. Invasive lobular carcinoma [8520/3]
2. In situ Paget disease of nipple [8540/2].
There is no combination code for lobular carcinoma and Paget disease.
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.
