MP/H--Bladder: Are 8130 and rule H12 correct for this case? Bladder with papillary urothelial carcinoma with squamous cell differentiation.
Rule H8 applies, code the histology with the numerically higher ICD-O-3 code which is papillary transitional cell carcinoma, 8130.
Based on the information provided, there is a single bladder tumor, papillary urothelial carcinoma with squamous cell differentiation. Urinary sites rule H12 does not apply because this is a single tumor, not multiple tumors. In the single tumor H rules, H3 does not apply as this rule does not include papillary transitional cell carcinoma. Rule H4 is papillary carcinoma or papillary transitional cell carcinoma and refers you to Table 1. Table 1 does not list papillary urothelial carcinoma with squamous cell differentiation because there is no ICD-O-3 code for this histology. Table 1 does list transitional cell carcinoma with squamous differentiation as code 8120, however, the papillary transitional cell carcinoma is the higher code, 8130. We will review this situation for the next version of the rules.
Reportability--Brain and CNS: Is schwannoma of the extracranial part of a cranial nerve reportable? Some cranial nerves, like facial nerve, have intracranial and extracranial branches.
An extracranial schwannoma is not reportable. The schwannoma must arise on the intracranial part of the nerve to be reportable.
First course treatment--Breast: When Lupron is given as cancer-directed treatment for metastatic breast cancer, should it be coded as Hormone Therapy or Other Therapy? See Discussion.
Per the SEER*Rx Database, Lupron is coded as Other Therapy for breast cancer until such time that it receives FDA approval. However, SINQ 20021042 states Lupron should be coded as Hormone Therapy when given as cancer-directed therapy. These two sources contradict each other.
Information regarding hormone therapy for breast cancer in both the SEER*Rx Database and the National Cancer Institute's Cancer Topics website (http://www.cancer.gov/types/breast/breast-hormone-therapy-fact-sheet) seem to indicate that the SINQ answer is the correct choice. The NCI Cancer Topics website states that Lupron acts to block ovarian function and is an example of an ovarian suppression drug that has been approved by the FDA. The SEER*Rx Database Remarks section states that a combination of letrozole and leuprolide (Lupron) "is considered standard treatment for metastatic breast cancer and is sometimes used for treatment of early stage breast cancer." But the Remarks go on to state that Lupron should be coded as Other Therapy until it receives FDA approval.
It is unclear how to code Lupron for breast cancers when the NCI website indicates that it is standard treatment while the SEER*Rx Database states both that it is and that it is not standard treatment.
Code Lupron given for breast cancer in the "Other" treatment field using code 6 (other-unproven). Lupron is still not an approved hormone treatment for breast cancer and should not be coded in the hormone field.
Surgery of Primary Site: What is the most extensive, invasive or definitive surgical procedure when the second surgical procedure performed has a lower surgery code? See discussion.
5/xx/14 Segmental Mastectomy(24): Ductal carcinoma with <1mm marg 6/xx/14 Breast Re-excision (23): Residual ductal carcinoma 1.5mm, marg neg
The code in Surgical Procedure of Primary Site should correspond to the most invasive, extensive, or definitive surgery when the patient has multiple surgical procedures of the primary site even if there is no residual tumor found in the pathologic specimen from the more extensive surgery. The timing of the procedures does not affect the code choice.
Assign code 27 for the first example. Assign code 24 for the second example.
First course treatment/Chemotherapy/Drug category: Instructions in SEER*Rx state that Ibrance should be coded as chemotherapy. They also state that it is an endocrine-based therapy. Local physicians refer to Ibrance as hormone therapy. Please clarify.
For cancer registry data collection, follow the instructions in SEER*Rx. It is important for all data collection to be consistent for reporting of cancer information.
Per the FDA: Ibrance is a chemotheraputic agent which was approved for use WITH Letrozole. Letrozole is a hormonal drug which may be why the physicians are stating the patient is receiving hormones. Ibrance should not be given alone to treat breast cancer. This drug will not be changing categories in SEER*Rx.
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.
Reportability--Brain and CNS: Is "Lhermitte-Duclos disease" is reportable? See discussion.
The MRI states "Lhermitte-Duclos disease" but does not include "dysplastic gangliocytoma of cerebellum"; is this the same as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)"?
"Lhermitte-Duclos disease" alone can be interpreted as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)" and reportable. The WHO classification for CNS tumors lists this entity as "Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease)" signifying that the terms are used synonymously.
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.
