Histology--Breast: Does "cancerization" mean invasive for a breast tumor described as "DCIS with lobular cancerization"?
No, cancerization is not a synonym for invasive. Cells of DCIS can extend not only along the duct but also into the terminal lobules. This extension is referred to as lobular cancerization.
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.
Histology (Pre-2007)--Breast: What code is used to represent the histology "ductal adenocarcinoma with medullary features?"
For tumors diagnosed prior to 2007:
Medullary is a subtype of duct and "with features of" is a term that indicates a majority of tumor. If this is an invasive adenocarcinoma with no in situ component, code to 8510/3 [Medullary adenocarcinoma]. If only one of the components is invasive, code that component.
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.
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.
Histology (Pre-2007)--All Sites: How are "malignant cells" in a cytology or "probably malignancy" in a CT scan coded?
For tumors diagnosed prior to 2007:
Assign code 8001/3 [Tumor cells, malignant] when the only information available is a cytology report stating "malignant cells."
Assign code 8000/3 [Neoplasm, malignant] when then only information available is a CT report stating "probable malignancy."
See ICD-O-3 page 27 for an explanation of "cancer" [8000] and "carcinoma" [8010].
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.
CS Extension/CS Mets at Dx--Lung: How are these fields coded for bilateral pleural effusion for a right lung primary? A code of 72 in the CS Extension field leads to a T4, but bilateral pleural effusion is M1. Should CS Mets at Dx be coded 39?
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 bilateral malignant pleural effusion, code the ipsilateral malignant effusion in CS Extension and the contralateral malignant effusion in CS Mets at Dx. Assuming the bilateral pleural effusion is the furthest extension in this case, code CS Extension to 72 [Malignant pleural effusion]. Code CS Mets at Dx to 40 [Distant mets, NOS].
Histology (Pre-2007)--Breast: What code is used to represent the histology of "invasive ductal carcinoma and in situ ductal carcinoma, cribriform type"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8500/3 [ductal carcinoma] unless the combination is ductal and lobular.
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.
Multiple Primaries (Pre-2007)--Trachea/Lung: Would synchronous lesions, of the same histology, diagnosed in the right upper lobe of the lung and trachea be a single primary when the physician feels they are two separate primaries?
For tumors diagnosed prior to 2007:
According to SEER rules, abstract as one primary because although these sites have separate topography codes in ICD-O-3, they were coded to the same three-digit topography code in the first edition of ICD-O (SEER Program Code Manual, 3rd Edition, page 8, Exception B). Simultaneous lesions of the same histology in trachea and lung are one primary. Code the primary site to C399 [Ill-defined sites within respiratory system].
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.
Primary Site: How do you code the primary site when the tumor is identified in a bladder that was reconstructed using a stomach augmentation procedure and the pathology report states, "Bladder/prostate: adenocarcinoma arising within gastric mucosa, with the following features: highly infiltrative through the bladder wall"?
Code the Primary Site field to bladder [C67.9]. Code the location of the tumor as the primary site.
