MP/H/Multiple primaries--Urinary: In Aug 2008 Patient was diagnosed with Noninvasive Bladder Cancer. In Oct 2013 Patient was diagnosed with Transitional Cell Carcinoma of Right Ureter involving lamina propria, Noninvasive Transitional Cell Carcinoma Left Ureter and Invasive Transitional Cell Carcinoma of Prostatic Urethra. Is this a new primary and what is the primary site?

Rule M7 applies when comparing the 2008 diagnosis to the 2013 diagnosis: multiple primaries.

Rule M8 applies to the tumors identified in 2013: single primary.

Based on the information provided, code the primary site for 2013 to C689 because there is no indication of the site of origin among the involved sites.

Reportability--Brain and CNS: Is pseudotumor cerebri reportable?

Pseudotumor cerebri is not reportable. It is not a neoplasm. The pressure inside the skull is increased and the brain is affected in a way that appears to be a tumor, but it is not a tumor.

MP/H/Histology/neuroendocrine : How should the following histologies with neuroendocrine differentiation be coded?

1.  Bladder - Invasive urothelial carcinoma with neuroendocrine differentiation

2.  Nasopharnyx - Undifferentiated nonkeratinizing nasopharyngeal carcinoma with neuroendocrine differentiation

3.  Ductal carcinoma in situ (with neuroendocrine features) cribriform and solid patterns

See discussion.

We are starting to see more specific histologies with neuroendocrine differentiation. How are we to deal with these histologies and will this be addressed in the revised MP/H rules?

The term neuroendocrine is often included with other histologies and usually means that neuroendocrine cells are present but not neuroendocrine tumor.

1.  If the neuroendocrine cells are stated to be either small cell or large cell, code that histology; however, neuroendocrine, NOS mixed with urothelial does not have an applicable mixed code. Code histology to 8120.

2.   Code histology to squamous cell carcinoma, nonkeratinizing, NOS (8072/3). The neuroendocrine component is not specified as either small cell or large cell.

3.  Code to 8523/2 per MP/H Rule H6 as intraductal mixed with other types of carcinoma present.

Note that while neuroendocrine differentiation can be identified, it seems to have no prognostic implications. We have consulted with our site specific Subject Matter Experts on how best to capture neuroendocrine, NOS when combined with other histologies. These instructions will be included in the revision of the MP/H rules including the wording of MP/H breast rule H6.

Primary Site--Liver: What is the topography code for combined hepatocellular carcinoma/cholangiocarcinoma (M-8180/3) especially when there is no documentation that intrahepatic bile duct is the tumor site? Reports usually just indicate a liver mass(es) but since the intrahepatic ducts are within the liver, is the code C221 due to the cholangiocarcinoma component, thus making the case stageable?

If there is no further information about where the cancer originated, assign C220. Use ICD-O-3 as the source for coding topography. The topography code associated with combined hepatocellular and cholangiocarcinoma (8180/3) is C220 when there is no other information available, according to ICD-O-3.

Reportability--Bladder: Please explain the reportability of UroVysion for bladder cancer in the following circumstances.

1. Patient has positive UroVysion test and follow up biopsy is negative. Is this case reportable with a diagnosis date the date of the UroVysion?

2. Patient has positive UroVysion test and follow up biopsy is positive for cancer. Is the diagnosis date of the date of the positive UroVysion or the date of the positive biopsy? Thank you.

Do not report a case based on UroVysion test results alone. Report a case when there is positive histology, a physician statement of malignancy, and/or the patient was treated for cancer.

1. Do not report the case.

2. Report the case based on the positive biopsy.

Grade--Bladder: Do you use the grade stated on the pathology report for coding the grade/differentiation field for bladder and renal pelvis field? See discussion.

Please confirm correct coding for grade for papillary urothelial carcinoma of the bladder/renal pelvis and urothelial carcinoma of the bladder/renal pelvis. SEER Manual 2014 and 2015 state: "Do not use these tables to code grade for any other groups including WHO (CNS tumors), WHO/ISUP (bladder, renal pelvis), or FIGO (female gynecologic sites) grades." They also state "In transitional cell carcinoma for bladder, the terminology high grade TCC and low grade TCC are coded in the two-grade system" in the Grade section. These statements are not included in SEER Manuals prior to 2014.

Use the grade stated on the pathology report to code grade/differentiation for bladder and renal pelvis field unless the grade is stated to be WHO/ISUP grade.

Multiple primaries--Heme & Lymphoid Neoplasms: Is this 2 primaries? In 2011, a patient had a spinal mass biopsied positive for DLBCL and follicular lymphoma. The heme rules make this one primary coded as DLBCL. Patient had 2 rounds of chemo, but in 2014, he had a recurrent tumor in the same location. The 2014 biopsy was follicular lymphoma. Is this a new primary -- conversion of acute to chronic after treatment? Or is it the same, since FL was diagnosed in the original specimen?

Rule M13 applies, abstract as two primaries. Since both DLBCL and FL were present in 2011, rule M2 does not fit -- not a single histology. Rule M13 reflects the situation in this case much better: an acute neoplasm which was treated and a chronic neoplasm diagnosed later.

First course treatment/Hormone Therapy--Lung: How is this field coded when the patient receives Prednisone for a metastatic lung adenocarcinoma? See Discussion.

The SEER*Rx Database, Prednisone Primary Site indicates "Prednisone is used to treat multiple sites and histologies." The Remarks information states, "Prednisone may be coded as treatment (hormonal) for all sites and histologies. It is most often used as part of a drug regimen." While it is clear that Prednisone is coded as hormone therapy when administered as part of a drug regimen like CHOP, how is Prednisone coded when given outside of a drug regimen? Also, how is Prednisone coded for cancer-directed treatment of a metastatic lung primary? The NCI's PDQ does not list hormone therapy as cancer-directed treatment for a Stage IV lung adenocarcinoma.

In our specific case, Prednisone was started just after diagnosis, and before the completion of work-up proving distant metastasis. Often, Prednisone (or another hormone agent) is given as an ancillary treatment for the symptoms associated with the malignancy, and not as cancer-directed treatment.

 

Do not code Prednisone when it is given for symptoms. In most cases when Prednisone is given by iteself, not as part of a drug regimen, it does not affect the cancer and would not be coded as treatment.

Reportability--Brain and CNS: Is this diagnosis reportable? If this neoplasm originated in the spinal cord, it is reportable, correct?

Specimen is described as a 'spinal cord mass.' The final diagnosis is 'fragments of adipose tissue demonstrating vascular proliferations consistent with angiolipoma. No histologic evidence of malignancy.' The microscopic description says: Sections of the spinal mass reveal bone, cartilage, fibrous tissue and adipose tissue. The adipose tissue demonstrates increased vascularity with thin walled blood vessels seen with islands of delicate fibrous stroma. The histologic findings are compatible with fragments of angiolipoma.

The neoplasm is reportable if it originated in the spinal cord or is intradural (within the spinal dura; spinal nerve roots are intradural). If there is not enough information to determine the exact site of origin, do not report the case.

Primary Site--Testis:  What is the prmary site for a 38 y/o male diagnosed with testicular cancer in a formerly undescended testis that was treated with orchiopexy at age 10-11?  See discussion.

Should it be coded to where the testis was physically at the time of diagnosis (C621), or should it be coded to C620 to reflect the increased risk for developing malignancy in an undescended testis?

Code the primary site C621 (descended testis). The primary site of this neoplasm is a scrotal (descended) testis. The history of orchiopexy can be noted in a text field, but does not change the primary site in this case.
