Patient was diagnosed March 2023 with a neuroendocrine tumorlet of the rectum measuring 0.8 mm via excisional biopsy during colonoscopy.

Prior SINQ 20160011 (stomach specific) indicates microcarcinoid and carcinoid tumors are reportable. Microcarcinoid is a designation for neuroendocrine tumors of the stomach when they are less than 0.5 cm. in size.

Is the current rectal tumor a reportable gastrointestinal neuroendocrine tumor if it is less than 5 mm (i.e., is a neuroendocrine tumorlet equivalent to a microcarcinoid)?

Patient was diagnosed many years ago with adenocarcinoma of the prostate and treated with hormonal and radiation therapy. The patient recently underwent a TURP and is found to have adenosquamous carcinoma of the prostate. The pathology report comment states squamous carcinoma of the prostate is rare and is often associated with a history of hormonal or radiation therapy. There is no information indicating a history of a squamous carcinoma in the urinary system that could have involved the prostatic urethra.

Would the MP/H rules make this a second primary with the histology of 8560/3 [adenosquamous carcinoma]?

Patient was diagnosed in the blast phase of CML on a 4/2010 bone marrow biopsy. Pt failed Gleevec and progressed to the accelerated phase of CML in 10/2010.

Is this a single primary? This is not addressed in the hematopoietic rules. If this is a multiple primary, what rule should be applied?

Patient was diagnosed in September 2022 via excision of a 12 cm pelvic mass with final diagnosis of Myofibroblastoma with sarcomatous transformation.

Diagnosis comment states, “Most of the tumor is composed of conventional features of myofibroblastoma. However, a focal area demonstrates increased cellularity, fascicular growth and increased mitotic activity (up to 11 per 10 hpf), consistent with sarcomatous transformation (morphologically low to intermediate grade).”

Is this sarcomatous transformation describing a malignant transformation from an otherwise benign histology? If so, how should histology be coded in this case?

Patient was diagnosed in July 2022 with biopsy confirmed left kidney renal cell carcinoma. Initially, partial nephrectomy was planned for February 2023 but canceled at the last moment due to the patient’s “history of narcotic use.” The details of that cancellation were otherwise unclear. It appears the treatment plan was changed due to patient non-compliance.

Patient then had cryoablation of the tumor in May of 2023. Subsequent imaging in October found residual tumor, but no disease progression was noted. Again, additional ablation was offered but patient decided on surgical treatment which did not occur until December 2023.

Is the cryoablation second course due to a change of plan if there is no disease progression, recurrence, or treatment failure?

If the cryoablation is first course treatment, then would the partial resection also be first course treatment because it was documented as the treatment plan?

Patient was diagnosed in 2005 with multiple myeloma and following stem cell transplant 2005 was in complete remission.

On 2/1/10 an excisional biopsy of a soft tissue right flank mass showed plasmacytoma. On 3/2/10 the bone marrow biopsy was stated to be consistent with plasma cell dyscrasia. An outside attending physician stated the bone marrow biopsy was consistent with a relapse of myeloma. There was no radiologic evidence of disease elsewhere as of Feb 2010, only the soft tissue right flank mass. Patient initially presented for post-op radiation to the right flank and was treated 3/29/10. On 8/6/10 a biopsy of a right perinephric mass was positive for plasmacytoma. Subsequent xray on 8/16/10 of the right tibia and fibula showed lytic lesion consistent with progression of myeloma.

Using the Hematopoietic Database, the plasmacytoma in 2/1/10 is a second primary. How do the rules apply to the perinephric soft tissue disease and right tibia lesion? Are they separate new primaries? Or is all of this simply a recurrence of the original 2005 diagnosis as the attending physician states?

Patient was diagnosed in 2004 with acute myeloid leukemia [9861/3] and treated with chemotherapy and transplant. Now the patient has a biopsy of an umbilical mass that is positive for myeloid sarcoma (granulocytic sarcoma) [9930/3].

Patient was admitted in July 15, 2002. Per the H&P, patient was diagnosed 5 years ago with myelodysplasia. Patient had bone marrow biopsy about 5 years ago and then again on 6-10-02. Patient has become transfusion dependent since mid-March. Bone marrow on 6-10-02 was consistent with myelodysplastic syndrome with refractory anemia with bilineage dysplasia with excessive blasts. Impression: Myelodysplastic syndrome slowly evolving toward acute leukemia. Plan: start chemo. 7-16-02 bone marrow biopsy showed acute myeloid leukemia.

Can we assume that the myelodysplasia diagnosed 5 years ago was refractory anemia and therefore, patient's first reportable diagnosis would be the AML? Or is the 6-10-02 bone marrow biopsy showing refractory anemia to be the first reportable diagnosis because the term "myelodysplasia" is non-specific?

Patient underwent resection for adenocarcinoma of the rectum. Path final diagnosis stated: "Regional lymph nodes: met carcinoma in 18 of

43 lymph nodes. Pathologic stage (AJCC/UICC 6th edition): pT3, V2, pN2, pMx. See comment." Path comment: "There are additional macroscopic stellate deposits of carcinoma in the pericolic soft tissue. According to the 6th edition of the AJCC staging manual, these should be designated as "V2," indicating that there is a high likelihood that these represent foci of venous invasion."

Patient underwent excision of an oropharyngeal soft tissue mass revealing plasma cell neoplasm with extensive amyloid deposition. During work-up, bone marrow biopsy also revealed involvement by plasma cell neoplasm, with 5-10% of marrow cellularity. No amyloid seen in bone marrow. Patient was referred for radiation of the oropharyngeal mass. Per medical oncology qualifying best for the diagnosis of solitary extramedullary plasmacytoma with minimal marrow involvement. Decision made for observation by medical oncology in view of “minimal” bone marrow involvement. Question: Is rule M11 correct, and I abstract this case as a plasma cell myeloma, 9732/3, C421?
