For cases diagnosed 1998-2003:

Code the EOD-Extension field to 60 [Tumor thrombus in a renal vein, NOS]. A thrombus can be a bolus of tumor cells within a large vein that may or may not still be connected/contiguous with the primary tumor. However, both a discontinuous and contiguous thrombus are coded to 60.

For tumors diagnosed prior to 2007:

Because this 2003 recurrent bladder cancer was initially diagnosed prior to 1973, it is not reportable to SEER.

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.

Code OPTUNE in the Other Treatment field. See NovaTTF in SEER*Rx (http://seer.cancer.gov/seertools/seerrx/). NovaTTF is the pre-FDA approval name for OPTUNE.

If OPTUNE was administered for recurrence, be sure NOT to record it in the first course of treatment fields. Check with CoC if you have questions about coding treatment for recurrence.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Per Rule M10, abstract two primaries. Per the Heme DB, polycythemia vera [9950/3] transforms to an acute myelogenous leukemia [9861/3]. According to Rule M10, one is to abstract multiple primaries when a neoplasm is originally diagnosed as a chronic neoplasm (e.g., polycythemia vera) AND there is a second diagnosis of an acute neoplasm (e.g., acute myelogenous leukemia) more than 21 days after the chronic diagnosis.

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.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

Code the primary site to the sigmoid colon [C187] per Rule PH24. Code the primary site to the organ when lymphoma is present only in an organ. Based on the information provided, the lymphoma is present only in the sigmoid colon.

For tumors diagnosed prior to 2007:

Code "chromophil" to 8260 [papillary renal cell]. According to our pathologist consultant, in the case of chromophil, most authors regard this as more or less synonymous with papillary renal cell [8260]. "More or less" because papillary is an old term descriptive of the microscopic structure, while chromophil is newer and based on the cytology; because most of the latter are papillary the current usage assumes them to be equivalent.

1) The diagnosis "renal papillary (chromophil) carcinoma" tells us that the pathologist who wrote it was seeing both pattern and cytologic features, and is regarding papillary equivalent to chromophil; thus, code to 8260.

2) Code "chromophil renal cell carcinoma" to 8260.

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.

Focus, focal, and foci are variations of the same word. Focus (noun) describes an area or point of disease, either grossly or microscopically. Focal (adjective) relates to the area/focus of disease; an example is a prostate with focal adenocarcinoma. This means that the majority of the prostate is benign and the adenocarcinoma is confined to one small area/point. Foci (plural) describe more than one area/focus of disease. A prostate with foci of adenocarcinoma means the disease is multifocal (several areas/points of disease).

Chips are microscopic amounts of either tissue or tumor. A pathologist might examine several chips of prostate tissue, one of which contains a focus of adenocarcinoma.
