CS Site Specific Factor--Lymphoma: Can the International Prognostic Index (IPI) score be taken from a TNM form in the record? If so, what score would we code for "low" (0-1 points) and "high" (4-5 points)?
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, the IPI score from the TNM form can be used to code SSF 3. Without further information, code "low" as 000 [0 points]. Code "high" as 004 [4 points].
Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?
One primary. This is a good example of how the field effect occurs in the urinary system. From 2007 to 2008, Rule M8 says bladder and ureter tumors are not new primaries and would be documented as recurrences. Because other urinary sites are involved by 11/08 and by 06/09, do not make second primary of left ureter (Rule M4 does not apply).
MP/H Rules--Breast: Is inflammatory breast cancer always one primary per lifetime? Or is a subsequent inflammatory breast cancer a second primary if diagnosed more than five years later?
For cases diagnosed 2007 or later, a diagnosis of inflammatory breast cancer more than five years after a previous diagnosis of inflammatory breast cancer is a separate (new) primary. See rule M5 in the Breast Multiple Primary Rules.
Immunotherapy/Other
Therapy--Heme & Lymphoid Neoplasms: Is the elimination of immunosuppression
treatment coded as other treatment? An example is when a post-transplant
patient develops a malignant myeloproliferative neoplasm that subsides when
immunosuppression drugs are stopped.
Do not code as a treatment. Record the cessation of
immunosuppressive drug treatment in text to explain the patient’s change in
disease status.
Sugery of Primary Site--Breast: When a patient is simultaneously diagnosed with bilateral breast cancer and bilateral mastectomies are done, do you code the total mastectomies to 40 or 41 or 42?
Abstract cancer of the left breast and cancer of the right breast as separate primaries. Code the surgery for each primary independent of the other primary.
For the first primary, assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast].
For the second primary, assign the code for the procedure performed on that site.
EOD-Lymph Nodes--Breast: Are micrometastases in the lymph nodes, found only on immunohistochemical staining, coded as positive lymph nodes?
For cases diagnosed 1998-2003: Do not code as positive lymph nodes that have micrometastases diagnosed ONLY on immunohistochemistry. By traditional diagnostic methods, these are still negative lymph nodes.
Summary Stage and EOD ignore the IHC positive micrometastases for cases diagnosed through 2003. The collaborative staging system that begins with 2004 cases and is based on the sixth edition of TNM addresses this issue.
Histology: What code is used to represent the histology "endometrioid adenocarcinoma, villoglandular type"?
Assign code 8262/3 [Villous adenocarcinoma].
According to the WHO Classification of Tumours, Breast and Female Genital Organs (2003), villoglandular is one of four variants of endometroid adenocarcinoma. The corresponding ICD-O-3 code according to WHO is 8262/3.
Reportability--Skin: Is atypical intradermal smooth muscle neoplasm (AISMN) of the skin reportable? The comment on the path report states: Atypical intradermal smooth muscle neoplasm (AISMN) was previously termed "cutaneous leiomyosarcoma."
Atypical intradermal smooth muscle neoplasm (AISMN), previously termed "cutaneous leiomyosarcoma," is not reportable. It is classified as a borderline, /1, neoplasm.
Tumor Size/Bladder: The 2018 SEER Coding and Staging Manual says to use imaging over physical exam as priority for determining tumor size. If a bladder tumor is 4 cm visualized on cystoscopy, and is 2.8 cm on CT scan, which should be used as the clinical size? Is cystoscopy (endoscopy) a clinical exam or imaging?
For the case described here, use the size from the CT scan. Physical exam includes what can be seen by a clinician either directly or through a scope. A tumor size obtained visually via cystoscopy is part of a physical exam. Therefore, the imaging (CT) tumor size is preferred. Use text fields to describe the details.
