Reportability--Stomach: Is a well-differentiated neuroendocrine tumor of the stomach reportable?
Well-differentiated neuroendocrine tumor (NET) of the stomach is reportable. The WHO classification of digestive system tumors uses the term NET G1 (grade 1) as a synonym for carcinoid and well-differentiated NET, 8240/3.
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.
Reportability--Skin: Is this reportable? If so, what is the correct histology code? The pathology report says, " bx of 0.7 x 0.5 cm gray-pink papule on tan-pink skin of left inferior centra malar cheek revealed invasive SCC of skin, signet ring cell type, invading papillary dermis; LVI neg; "findings are diag of SCC exhibiting the rare signet ring histologic subtype"; deep margin positive for tumor but peripheral margins clear;".
Surgery of Primary Site--Breast: Is the surgery code 42 or 52? Does it matter that the procedure states no axillary LN, but the pathology found 2 additional LN? See discussion.
Procedure stated = Bilateral skin-sparing mastectomies, left axillary sentinel lymph node biopsy. On the pathology report it indicates two additional lymph nodes were removed that were not SLN. The axillary aspect measures 2 x 2 x 1 cm. Two lymph nodes are identified ranging from 0.5 up to 1 cm. The lymph nodes are bisected and entirely submitted. Final Diagnosis Left breast, mastectomy including nipple: no residual carcinoma; FINAL DIAGNOSIS for LN = Lymph nodes, left axillary sentinel #1; excision: Two lymph nodes examined - negative for tumor (0/2); Two lymph nodes - negative for tumor (0/2)
Assign surgery of primary site code 42. It is possible to obtain lymph nodes in a mastectomy specimen without an axillary dissection. Remember to capture the excised lymph nodes in the scope of lymph node surgery field.
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.
MP/H Rules/Histology--Thyroid: When is 8341/3, papillary microcarcinoma coded? The code description in ICD-O-3 is followed by (C739), yet there are two SINQ answers that tell us specifically to not use this code for thyroid primaries. Even the first revision of ICD-O-3 still carries the (C739) as part of this code, which goes against SINQ 20110027 and 20081127.
Per the WHO Tumors of Endocrine Organs, for thyroid primaries/cancer only, the term micropapillary does not refer to a specific histologic type. It means that the papillary portion of the tumor is minimal or occult (1cm or less in diameter) and was found incidentally. WHO does not recognize the code 8341 and classifies papillary microcarcinoma of the thyroid as a variant of papillary thyroid and thereby should be coded to 8260. If the primary is thyroid and the pathology states papillary microcarcinoma or micropapillary carcinoma, code 8260 is correct. This information will be included in the upcoming revisions to the MP/H manual.
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.
MP/H Rules/Multiple primaries--Breast: Does rule M10 apply in this situation?
L breast biopsy = INVASIVE DUCTAL CARCINOMA
L breast simple mastectomy = 2.0 cm INVASIVE DUCTAL CARCINOMA with an incidental finding of separate 1.0 cm INVASIVE LOBULAR CARCINOMA; pathologist specifically states the tumors are morphologically different. The tumors are both pure Ductal/pure Lobular.
Yes, Breast rule M10 applies. This case is a single primary.
Follow the MP/H rules even though the "pathologist specifically states the tumors are morphologically different" so that situations like this are reported consistenty accross cancer registries, regions, and states for consistent national reporting.
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.
