First course treatment/Surgery of Primary Site--Anus: Would infrared coagulation be coded as treatment for AIN III of the anus/anal canal? See discussion.
SINQ 20051064 indicates infrared coagulation is not treatment for cancer. Internet search explains that infrared coagulation delivers heat to destroy the tissue so it can be removed. In our region it is currently used to treat internal and external anal low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL). While it is understandable that this wouldn't be coded as treatment for an invasive anal primary, could it be treatment for an in situ tumor? If it is treatment, should it be coded under Surgery code 15
The answer to SINQ 20050164 still applies. Do not code infrared coagulation as cancer treatment. It is used to coagulate blood vessels and not to destroy cancer tissue.
Behavior--Breast: Is behavior for encapsulated papillary carcinoma (EPC) of the breast coded as noninvasive or invasive?
The pathologist has the final say on behavior. Code behavior based on the pathologist's final diagnosis. See Rule F in ICD-O-3.
According the WHO Classification of Breast Tumors, encapsulated papillary carcinoma of the breast is in situ, /2. Encapsulated papillary carcinoma with invasion is assigned /3. WHO describes "frank invasive carcinoma" for this histology as "neoplastic epithelial elements infiltrate beyond the fibrous capsule of encapsulated papillary carcinomas." WHO cautions that true infiltration should be "differentiated from entrapment of neoplastic epithelial cells in the fibrous capsule and from epithelial displacement into the biopsy site, which is frequently encountered following needle-core procedures of papillary lesions."
Histology--Heme & Lymphoid Neoplasms: Should the 1995 diagnosis be changed to plasmacytoma? A 1995 case on the central registry database indicates that MRI and bone surveys revealed a pubic ramus lesion that was biopsied. There are no other bone lesions. A bone marrow biopsy was negative. The pathologist's diagnosis at that time was "Plasma Cell Myeloma". In 2013 there was a positive bone marrow biopsy and a diagnosis of Plasma Cell Myeloma. In 2013, a history of "sequential plasmacytomas since 1995" was mentioned. Since the 1995 diagnosis was only a solitary bone lesion with no marrow involvement, it certainly seems to fit a diagnosis of plasmacytoma better than myeloma.
Do not change the 1995 diagnosis in this case. It is best to code the histology according to information from the time of the diagnosis. Using information obtained many years later is less reliable.
Grade--Liver: How should grade be coded for a liver lesion treated with radio frequency ablation (RFA) followed by a transplant showing moderately differentiated hepatocellular carcinoma? See discussion.
The SEER Manual emphasizes the importance of coding grade only prior to neoadjuvant treatment as systemic treatment and radiation can alter a tumor's grade. This patient did not have neoadjuvant chemotherapy or radiation, but did undergo a prior surgical procedure (RFA) in an attempt to destroy tumor tissue. The subsequent transplant showed residual moderately differentiated HCC.
For this case, record the grade specified even though it is after RFA. RFA is not systemic or radiation treatment and should not alter the grade.
MP/H Rules/Histology--Sarcoma: What would be the morphology code for a low grade myofibroblastic sarcoma of the left distal forearm? I tried several different combinations but the closest I could come up with is myosarcoma.
Assign code 8825/3. Apply the ICD-O-3 Matrix Concept, Rule F, page 29 of the hardcover ICD-O-3. The WHO Classification of Soft tissue and Bone, page 85, lists low grade myofibroblastic sarcoma, also called myofibrosarcoma, 8825/3.
MP/H/Multiple Primaries--Urinary: Is this one primary with a C689 primary code and morphology 8130/3? Or is this 2 primaries: 1. C679 8130/3 and 2.C680 8120/2. See discussion.
Urinary: Transitional Cell Carcinoma and open prostatectomy: Path from Bladder: Papillary and solid transitional cell carcinoma of bladder - grade II and III Stage A.
Path from prostatectomy: The prostatic tissue samples shows areas of urothelia carcinoma in situ - related to the tumor present in the bladder.
Conclusion: Prostatectomy showing foci of transitional cell carcinoma in situ of prostatic urethra.
Abstract a single primary, C679 8130/3. Rules M2 and H4 apply. Transitional cell/urothelial carcinoma in the prostatic urethra is likely an extension from the known bladder TCC in this case, not a separate primary. See prostatic urethra on page 63 in the Urinary Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
MP/H Rules/Multiple primaries--Prostate: Is duct carcinoma of the prostate the same as an adeno/acinar carcinoma of the prostate? Specifically, does rule M3 apply when there is an adenocarcinoma of the prostate followed by a duct carcinoma of the prostate or a duct carcinoma followed by adenocarcinoma?
Rule M3 does not apply to adenocarcinoma followed by duct carcinoma of the prostate or vice versa. Rule M3 pertains to cases of adenocarcinoma and acinar carcinoma. These two terms, adenocarcinoma and acinar carcinoma, are equivalent for the purpose of applying the MP/H rules to prostate cases. See page 77 of the Other Sites Terms and Definitions, http://www.seer.cancer.gov/tools/mphrules/mphrules_definitions.pdf
First course treatment: When a patient has a Haplo bone marrow transplant, is this coded as an allogenic bone marrow transplant since part of his marrow was used in addition to a donor?
Use code 12 in the Hematologic Transplant & Endocrine Procedures data field. Per the NCI, this procedure is an allogeneic transplant.
Rather than wiping out a patient’s immune system before transplanting donor bone marrow, doctors administer just enough chemotherapy to suppress the immune system, which keeps patients from rejecting the donated marrow without harming their organs. The procedure requires just a half-match, meaning that a patient’s parents or children could be suitable donors. AKA: Half-match transplants.
Reportability--Pancreas: Is a solid pseudopapillary neoplasm of the pancreas reportable?
Solid pseudopapillary neoplasm of the pancreas is reportable. According to the WHO classification, it is a "low-grade malignant neoplasm…[which] frequently undergoes hemorrhagic-cystic degeneration and occurs predominantly in young women."
Assign topography code C25 with the appropriate 4th digit. Code the histology as 8452/3.
MP/H Rules/Histology--Bladder: What is the correct histology code for this situation? See discussion.
Patient has 2 bladder tumors, both invasive -- one is transitional cell carcinoma (8120/3) and the other is papillary TCC (8130/3). They have the same extent of disease, both involve the lamina propria. Is this 8120, because of the Note under rule H11 or is this 8130 because under rule H12, it says 'papillary carcinoma and transitional cell carcinoma'? If so, what is the meaning of the note under rule H11?
Rule H12 applies, code to 8130.
The note under H11 is intended to explain the order of the rules; that is, why the rule to code papillary transitional/urothelial cell carcinoma (H12) follows the rule to code transitional/urothelial cell carcinoma (H11).
