How many primaries should be reported when a 12/19/14 RUL lung wedge resection shows: 2.0 cm invasive adenocarcinoma (8140/3) and an additional RUL wedge resection during the same procedure shows: multifocal adenocarcinoma in situ (bronchioloalveolar carcinoma), non-mucinous type (8252/2) size: 1 mm – 2 mm; followed by a 2/12/15 left upper lobectomy also showing Adenocarcinoma, invasive at several foci, with a prominent bronchioloalveolar (in situ) component….tumor focality: multifocal (10 cm mass, 6 cm mass and numerous smaller foci)?

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.

There are multiple SEER Notes in the Breast Surgery Codes of Appendix C instructing us to code tissue expanders as reconstruction but none address the type of reconstruction to be coded.

1. Is a tissue expander always equivalent to Implant reconstruction?

2. Is AlloDerm always equivalent to Tissue reconstruction?

3. Is the combination of AlloDerm and tissue expander always equivalent to Combined (tissue and implant) reconstruction?

LARYNGOSCOPY - ENDOLARYNGEAL EXAM WAS GROSSLY UNREMARKABLE EXCEPT THAT SHE APPEARS TO HAVE A T1A SQUAMOUS CELL CARCINOMA OF THE RIGHT TRUE VOCAL FOLD. IT EXTENDS FROM ALMOST THE ANTERIOR COMMISSURE ALL THE WAY BACK TO THE VOCAL PROCESS AND IS EXOPHYTIC IN NATURE. IT DOES NOT EXTEND INTO THE VENTRICLE OR ONTO THE FALSE VOCAL FOLD. NO SUBGLOTTIC EXTENSION IS SEEN. A. RIGHT POSTERIOR FALSE VOCAL CORD FOLD, BIOPSY:  SQUAMOUS CELL CARCINOMA IN SITU. B. RIGHT POSTERIOR TRUE VOCAL CORD FOLD, BIOPSY:  SQUAMOUS CELL CARCINOMA, SUSPICIOUS FOR INVASION. C. RIGHT MID TRUE VOCAL CORD, BIOPSY:  SQUAMOUS CELL CARCINOMA, SUSPICIOUS FOR INVASION. D. RIGHT ANTERIOR TRUE VOCAL FOLD, BIOPSY:  INVASIVE AND IN SITU SQUAMOUS CELL CARCINOMA, MODERATELY DIFFERENTIATED.

The diagnosis date is 2/24/14.  The pathology report of the pancreas shows: Well-differentiated neuroendocrine tumor (NET), low grade (WHO G1 of 3). Addendum: Ki-67 confirms low grade of pancreatic endocrine tumor (less than 2% Ki-67/MIB-1 index). Chromogranin confirms the endocrine nature of the tumor. The Pre and Post Op Diagnosis is pancreatic neuroendocrine tumor consistent with insulinoma. AJCC Stage as noted on path report: pT1, pNX, pM.

The physician states: The patient has a well-documented insulinoma. Biochemistries confirmed the disease and it is localized in the tail of the pancreas.

The issue with NETs is that pathology report reflects what is seen or what is quantified under the microscope; often, there is a specimen without the accompanying medical history and clinical signs. Many of these NETs are specified on the basis of the hormone, as usually measured in the blood, that is overproduced, something not seen microscopically. All of the islet cell tumors are NETs. The insulinoma in the example above is a well-differentiated NET that is causing insulin to be over-produced. Thus, the diagnoses are not discordant; insulinoma is a more specific NET.

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.

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.
