MP/H Rules/Histology--Bladder: What is the correct histology code for this situation? See discussion.
Patient has 2 bladder tumors, both invasive -- one is transitional cell carcinoma (8120/3) and the other is papillary TCC (8130/3). They have the same extent of disease, both involve the lamina propria. Is this 8120, because of the Note under rule H11 or is this 8130 because under rule H12, it says 'papillary carcinoma and transitional cell carcinoma'? If so, what is the meaning of the note under rule H11?
Rule H12 applies, code to 8130.
The note under H11 is intended to explain the order of the rules; that is, why the rule to code papillary transitional/urothelial cell carcinoma (H12) follows the rule to code transitional/urothelial cell carcinoma (H11).
Reportability--GIST: The 2014 SEER Program Coding and Staging Manual and the answer to SINQ 20100014 appear to conflict with respect to reporting GIST cases. The manual states (p.5, exception 1) that we are to accession the case if the patient is treated for cancer. However, the patient in Example #7 in the SINQ discussion is receiving chemotherapy, but is deemed not reportable. This is a problematic issue in our area, as pathologists prefer using the NCCN “Risk Stratification of Primary GIST by Mitotic Index, Size and Site” table rather than stating whether the tumor is benign or malignant. Although they tell us that moderate or high risk should receive treatment, they will not characterize them as malignant.
Determining reportability for GIST is problematic because of the reluctance of pathologists to use the term "malignant" for GIST cases. If you can document the pathologist's terminology and case characteristics (e.g. treatment) that correspond to "malignant" for your registry as part of the registry's policies and procedures, you can report those cases as malignant.
The exception cited above in the SEER manual pertains to a clinical diagnosis with a negative pathology report. Normally, the negative pathology report would override the clinical diagnosis and the case would not be reportable. However, if the patient is treated for a malignancy in spite of the negative pathology, report the case.
MP/H/Histology--Kidney, renal pelvis: What is the histology code for renal cell carcinoma translocation type?
Code renal cell carcinoma translocation type as renal cell carcinoma, NOS, 8312. While WHO recognizes renal cell carcinomas with associated translocations, there is no specific ICD-O-3 code for this variant of renal cell carcinoma.
MP/H Rules: Regarding rules for Renal Pelvis, ureters, bladder & urethra - Please clarify Rule M8. Rule M8 references Table 1, but table 1 is a table of histologies not primary sites, Rule M8 also seems to contradict Table 2 and Rule M10. Does it matter where the first primary is, ie bladder then urethra or bladder then renal pelvis?
Table 2 does not apply to diagnoses in 2007 and later. A watermark over (or near) Table 2 states "Do not use for cases diagnosed on or after 2007." Table 2 lists previous SEER site groupings for cases prior to 2007.
The MP/H rules are in hierarchical order. Use the first rule that applies. When Rule M8 applies, there is no need to check Rule M10. Rule M8 is for the urinary sites listed and derives single primary. Rule M10 is for all sites, except the sites listed in Rule M8, and derives multiple primaries.
It does not matter where the first primary is, i.e. bladder then urethra or bladder then renal pelvis. If there are two or more tumors in two or more of these four sites listed in Rule M8 with histologies listed on Table 1, abstract as a single primary.
MP/H Rules/Histology--Bladder: What is the correct histology for the following bladder case and how do you determine? See discussion.
8/1/10 CYSTOSCOPY -- MULTIPLE BLADDER TUMORS INVOLVING POSTERIOR WALL, DOME & BLADDER NECK AREA. LARGEST WOULD BE MORE THAN 5 CM IN SIZE. 8/17/10 path -- BLADDER TUMORS:PAPILLARY TRANSITIONAL CELL CARCINOMA OF urinary bladder, GRADE III. ONE FRAGMENT OF TISSUE SHOWS NECROTIC CHANGE WITH APPARENT TRANSFORMATION TO A HIGH GRADE SARCOMATOID VARIANT W ITH EXTENSIVE SUBMUCOSAL INVASION & FOCAL AREA SUGGESTIVE OF ANGIOLYMPHATIC INVASION NOTED. MAJORITY OF TUMOR APPEARS CONFINED TO MUCOSAL SURFACE W ITH NO OTHER AREAS OF DEFINITIVE SUBMUCOSAL INVASION FOUND.
Code 8122/3 (UC/TCC, Sarcomatoid). Rule H5 and Table 1 apply.
This is based on the information provided: Transitional Cell Carcinoma with sarcomatoid variant, and Table 1 in Terms and Definitions for "Ureter/Renal Pelvis/Bladder".
Grade--Heme & Lymphoid Neoplasms: Why isn't "T-cell granular lymphocytic leukemia" (9831/3) coded as "5 T-cell" instead of "9" as specified in the Heme database? My path department did not specify any type of grade, but since "T-cell" is part of the name, wouldn't you code it to "5"?
Assign code 5 when the diagnosis on the pathology report specifies "T-cell granular lymphocytic leukemia." The Heme DB grade instruction states "Code grade specified by pathologist. If no grade specified, code 9." In this case, T-cell was specified - code it. The code for T-cell (5) was not automatically assigned in the Heme DB because of the alternate names for this neoplasm. Some of these include NK-cell. Assign code 8 for alternate names with NK.
The alternate names are: Chronic lymphoproliferative disorder of NK cells, Chronic NK-cell lymphocytosis, Chronic NK-large granular lymphocyte (LGL) lymphoproliferative disorder, CLPD-NK, Indolent large granular NK-cell lymphoproliferative disorder, NK-cell lineage granular lymphocyte proliferative disorder, NK-cell LGL lymphocytosis
Primary Site/In Situ: How is primary site coded for an in situ carcinoma arising in a mucinous cystadenoma with ovarian stroma (focal) located in the right lobe of the liver? See discussion.
The SEER Coding and Staging Manual instructs one to code the primary site to the location where the tumor originated, in this case the liver. However, there is no CS Extension code for in situ tumors found in the CS Manual Liver Schema.
Based on the information provided, the primary site is liver. Submit the CS question to the CoC CAnswer Forum, http://cancerbulletin.facs.org/forums/content.php
MP/H Rules/Histology--Bladder: What is the correct histology code for a diagnosis of urothelial plasmacytoma carcinoma of the bladder per pathology report?
Assign code 8120/3, urothelial carcinoma, NOS, to urothelial plasmacytoma carcinoma of the bladder. The WHO classification describes plasmacytoid variants of urothelial carcinoma. There is no specific ICD-O-3 code for these variants; however, and 8120/3 must be used.
Surgery of Primary Site--Lung: How is surgery coded when a patient undergoes a mediastinoscopy with mediastinal lymph node sampling and then a later upper lobectomy? See discussion.
The mediastinal nodes were submitted as a separate specimen. The patient also had several peribronchial nodes identified within the lobectomy specimen.
Does code 33 (Lobectomy with mediastinal lymph node dissection) require a complete mediastinal lymph node dissection (i.e. the removal of all lymph nodes in mediastinal chain(s) as opposed to a selective sampling/dissection of lymph nodes from multiple mediastinal chains)?
Assign code 33 in this situation. Code 33 can include mediastinal lymph node sampling.
