Surgery of primary site--Lung: Should microwave ablation be coded as treatment for lung cancer, and if so, how should it be coded?
Code microwave tumor ablation as surgery. For lung, assign code 15.
This question was discussed by the technical advisory group – a small group of representatives from each standard setter which meets periodically. The group agreed on this consensus answer.
First course treatment/Other therapy: How is Sirolimus (Rapamycin) to be coded when given with known chemotherapy agents in a clinical trial? See discussion.
The SEER*Rx Database lists Sirolimus as an ancillary agent under the Category section, but as an mTOR inhibitor under the Subcategory. The Remarks section indicates Sirolimus (AKA Rapamycin) is an immunosuppressant, but is also a type of serine/threonine kinase inhibitor. Other types of kinase inhibitors (including Temsirolimus) are types of Chemotherapy. Although the Coding section states this drug should not be coded, Primary Sites (NSCLC and glioblastoma) are listed for this drug.
The SEER*Rx Database page for this drug is confusing. Please address the following.
1) Should Sirolimus not be coded when it is being given as a kinase inhibitor or an immunosuppressant?
2) If Sirolimus is ever treatment, should it be coded only for the primary sites listed?
3) If Sirolimus is given as part of a non-blind clinical trial for another site other than NSCLC or glioblastoma, should the Other Therapy field be coded to 2 [experimental - other treatment]?
Sirolimus is used to treat GVHD (graft versus host disease) and is not coded as treatment. Even though the sub-category is mTOR inhibitor it does not automatically mean it is a chemotherapeutic agent. Sirolimus affects cells differently than Temsirolimus. The chemical compounds differ between these drugs. In order to code rapamycin, the drug given must be stated to be either the analog or ester compound. The SEER*RX database has been corrected and NSCLC/glioblastoma are no longer listed for sirolimus.
We researched clinical trials and found several that include sirolimus with other chemotherapy drugs for patients who either have received or will be receiving bone marrow transplants for hematologic diseases. In this case it is not coded. There are a few trials that are looking at sirolimus as a treatment for bladder, prostate, nerve sheath tumors, MDS, and AML. For these cases it would be coded in Other (code 2).
Reportability--Bone: Is an "atypical cartilaginous tumor" reportable? See Discussion.
Patient had a core needle biopsy of the right acetabulum. Final diagnosis on the path report is: Atypical cartilaginous tumor (formerly chondrosarcoma, grade 1).
Is this cell type reportable? If so, is it reportable only because the pathologist recorded clarifying text in parentheses? If the text in the parentheses was not available, is the histology "atypical cartilaginous tumor" reportable?
Atypical cartilaginous tumor of bone is not reportable. The WHO terminology is "atypical cartilagenous tumor/chondrosarcoma grade I." WHO classifies this entity as low malignant potential (behavior code /1).
Chondrosarcoma grade II or grade III is reportable based on the WHO classification of malignant (behavior code /3).
MP/H Rules/Histology--Bladder: Can the histology for a high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" be coded to sarcomatoid transitional cell carcinoma (8122/3)?
Example; TURBT, Final Diagnosis - Urothelial carcinoma, high grade. Type/grade comment: Extensive sarcomatoid dedifferentiation is present (40-50% of tumor volume).
Code high grade urothelial carcinoma described as having "extensive sarcomatoid dedifferentiation" to sarcomatoid transitional cell carcinoma (8122/3).
MP/H Rules/Histology--Prostate: What is the histology code for a prostate case whose histology reads “adenoca with mixed ductal and acinar variants?
Assign 8523/3.
The 2013 revision to ICD-O-3 has a new code for mixed acinar ductal carcinoma; however, this new code will not be implemented in the U.S. until 2018 or later. Page 7 of the Guidelines for ICD-O-3 Update Implementation document released by NAACCR 1/1/2014 instructs us to use 8523/3 in the meantime.
Birthplace/Place of birth, country: For patients originally born in a country that is currently listed as "historic only", where the original birth country now has a one-to-many relationship with the current country, how should the reported original birthplace be coded? (Example: Yugoslavia)
Assign code for Europe, NOS (ZZE) for Yugoslavia, NOS, without further information.
First course treatment/Immunotherapy--Prostate: Is XGEVA, given for bone mets from prostate cancer, abstracted as immunotherapy, or is it an ancillary drug and not recorded?
Do not record XGEVA when given for bone mets from prostate cancer. See SEER*Rx for more information.
Radiation Therapy--Breast: Are iodine 125 (I-125) seed implants for breast cancer coded as brachytherapy or as a localization technique similar to wire localization? See Discussion.
We are seeing many I-125 seed implants for breast cancer. Many of my associates are coding them as brachytherapy. I think they are the newest of the localization technique like wire localization but with greater accuracy. Most are done the same day as the surgery so brachytherapy does not make sense. Which is correct?
I-125 seeds could be used for brachytherapy for breast cancer or as a localization technique for nonpalpable breast tumors. If the seeds were in place a short time and removed as part of a breast surgical procedure, they were likely used for tumor localization. Radioactive seed localization (RSL) is thought to be more precise than the wire implantation technique for localizing lesions.
MP/H Rules/Histology--Skin: What histology code and MP/H Rule apply to a skin primary with the final diagnosis, ? See Discussion.
The patient had an upper arm shave biopsy with final diagnosis of basaloid carcinoma with squamous and neuroendocrine differentiation. The pathologist also comments: Further resection was negative for residual malignancy.
Would SINQ 20150033 apply, thus resulting in final histology of carcinoma with neuroendocrine carcinoma (8574/3)?
Assign 8574/3 according to Other Sites rule H17 for basaloid carcinoma with squamous and neuroendocrine differentiation.
There is no combination code that includes basal cell, squamous, and neuroendocrine. We can combine basal cell with squamous, 8094/3, or carcinoma with neuoendocrine differentiation, 8574/3. Rule H17 directs us to assign the higher code, 8574/3.
First course treatment/Radiation Therapy--Prostate: How do you code fiducial markers for prostate cases?
Do not code fiducial markers as a form of radiation treatment; rather, code the radiation therapy in the radiation treatment section. Fiducial markers are small metal spheres, coils, or cylinders that are placed in or near a tumor to help guide the placement of radiation beams during treatment.
