Patient is diagnosed with invasive ductal carcinoma (IDC), right breast, receives HT, radiation therapy, and surgery. The same patient is diagnosed with LCIS, left breast one month later--recommend surveillance only (no surgery). Is the HT for the left breast coded at all? I think for COC/NCCN, we do not, but for SEER what would I do? Treatment in the SEER Manual 2018 states, "Code the treatment on each abstract when a patient has multiple primaries and the treatment given for one primary also affects/treats another primary." The example include bladder/prostate and ovarian/cervix. It also states, "Code the treatments only for the site that is affected when a patient has multiple primaries and the treatment affects only one of the primaries." The example includes colon/tonsil. Breast LCIS treatment appears complicated. Per NCCN guidelines, this condition no longer has recommendations, however it appears as though they still state that if a core biopsy is done and is LCIS, follow up should be ultrasound or surgical excision. Nowhere does it state hormone is recommended.

Would you code an excisional biopsy as Surgery for the following case?

The patient presented with a large protruding polypoid anal canal mass. The diagnosis of malignancy was made following a procedure referred to by the surgeon as an excisional biopsy. The protruding portion of the anal canal mass was excised, but the deep margin was grossly involved. The PE exam after the "excisional biopsy" found a firm mass, 4 cm in length on DRE. Further work-up with imaging showed gross residual disease extending to adjacent skeletal muscle (external anal sphincter). Although the internal/protruding anal canal portion of the tumor was excised, there was clearly extensive residual tumor. The patient underwent definitive concurrent chemoradiation only; subsequent surgery was not planned or performed.

The 2016 WHO Classification of Tumours of the Urinary System appears to be moving away from using Fuhrman grading toward using WHO/ISUP grade. These seem like similar 4 grade staging systems; however, the SEER Manual specifically states to not use the Special Grade System table for WHO/ISUP. We are seeing the WHO/ISUP grade being used on 2016 pathology reports.

Examples of new grading for renal cell carcinomas

Histologic type: Clear cell renal cell carcinoma

Histologic grade (WHO/ISUP 2016): Grade 3 in a background of 2 (of 4).

And

Histologic type: Clear cell renal cell carcinoma

Histologic grade (ISUP): Grade 2.

Patient had a right thyroid lobectomy on 12/2022, with initial diagnosis of “thyroid carcinoma pending expert consultation for definitive classification.”  The slide review documented in the addendum shows a final diagnosis of “Angioinvasive oncocytic thyroid neoplasm, see comment.”  The subsequent comment states, “I would classify this lesion as an angioinvasive oncocytic thyroid neoplasm with features worrisome for a poorly differentiated oncocytic carcinoma.”  The comment goes on to state, “Additional immunostains were performed which demonstrate the carcinoma cells are positive for thyroglobulin and negative for calcitonin. The diagnosis remains unchanged.”

Example

July 2022, Brain CT describes a mass appearing to be centered on the petrous aspect of the temporal bone with intracranial and extracranial extension.

July 2022, Brain MRI describes an extra-axial mass centered in the right jugular bulb with intracranial and intraosseous extension as well as extension within the internal jugular vein. 

September 2022, Resection operative report surgical findings are of a calcified mass filling middle ear, abutting stapes and appearing to enter the stapes obturator foramen, debulked. Final diagnosis is right middle ear meningioma, WHO grade I of III.

Is this a reportable intraosseous meningioma of the temporal bone/skull base, or a non-reportable meningioma arising in a meningocele within the middle ear?
