Sugery of Primary Site--Breast: When a patient is simultaneously diagnosed with bilateral breast cancer and bilateral mastectomies are done, do you code the total mastectomies to 40 or 41 or 42?
Abstract cancer of the left breast and cancer of the right breast as separate primaries. Code the surgery for each primary independent of the other primary.
For the first primary, assign code 41 [Total (simple) mastectomy, NOS WITHOUT removal of uninvolved contralateral breast].
For the second primary, assign the code for the procedure performed on that site.
Reportability/Breast: Is lobular carcinoma in situ (LCIS) reportable? The eighth edition, American Joint Commission on Cancer (AJCC) Cancer Staging Manual does not stage LCIS.
Yes, LCIS is reportable. Staging does not determine reportability. Follow the reportability requirements of your state and national standard setter. SEER reportability requirements are found in the SEER manual starting on page 5, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf
Primary Site--Unknown & ill-defined site: Should the primary site be coded to C809 [Unknown primary site] or C761 [Thorax, NOS] if the patient died following a limited work-up that included on a cytology on pericardial fluid that was positive for poor differentiated adenocarcinoma?
Based on the information provided, code the primary site to C809 [Unknown primary site]. There is not enough information provided to suggest that the primary site is the thorax or any other location.
MP/H Rules/Multiple Primaries--Bladder: The new multiple primary rule M7 states that tumors diagnosed more than three years apart are multiple primaries. Does this apply to in situ bladder tumors that occur more than three years apart and to an in situ tumor that occurs three years after an invasive tumor?
For cases diagnosed 2007 or later, use the MP/H rules in order. Rule M6 comes before rule M7.
M6 states that bladder tumors with certain histologies are a single primary. It is a single primary regardless of timing if there is any combination of:
papillary carcinoma [8050]
transitional cell carcinoma [8120-8124]
papillary transitional cell carcinoma [8130-8131]
Rule M7 applies to bladder tumors with histologies other than those listed above. If you have such a case, rule M7 applies to in-situ tumors and to an in situ three years after an invasive.
First course treatment--Heme & Lymphoid Neoplasms: Is the use of the corticosteroid, Clobetasol, cancer-directed treatment for mycosis fungoides or is it only used to treat the side effects of that disease?
Clobetasol is not cancer-directed treatment at this time.
Note: Question originally submitted in 2010. During 2014 review, this was checked and Clobetasol is still not cancer directed treatment for Mycosis Fungoides.
Reportability: Is a "pleomorphic hyalinizing angiectatic tumor of soft parts (PHAT)" reportable if the case has a TNM stage assigned and is stated by the pathologist to be a rare intermediate grade sarcoma?
Pleomorphic hyalinizing angiectatic tumors of the soft parts are not reportable.
According to our pathologist consultant, PHAT is a borderline malignancy (/1). While the true nature of these tumors is under debate (reactive vs. neoplastic), so far none have metastasized.
EOD-Size of Primary Tumor--Colon: When an adenocarcinoma is stated to be arising in an adenoma and the "tumor size" stated in the final pathologic diagnosis is the same size as the mass described in the gross description, should we assume that the entire polyp has been totally/near totally replaced by tumor and code the tumor size stated in the final path diagnosis?
For cases diagnosed 1998-2003:
Code the EOD-Size of Primary Tumor field as stated by the pathologist in the final pathologic diagnosis. If the size of the tumor is the same as the size of the polyp, assume the polyp was completely replaced by tumor.
EOD-Extension--Sarcoma: How is this field coded for a soft tissue sarcoma that involves the overlying skin?
For cases diagnosed 1998-2003: It depends on the location of the soft tissue sarcoma. If the tumor is very superficial, code EOD-Extension to 60 [Adjacent organs/structures]. However, if the soft tissue sarcoma is between muscles or "deep" according to the AJCC definition, then it would have to grow through the superficial fascia to get to the skin. In this case code EOD-Extension to 80 [Further contiguous extension].
Primary Site--Esophagus: What is the difference between C15.5 [Lower third of esophagus] and C15.2 [Abdominal esophagus]?
These descriptions represent the use of two different ways the esophagus can be divided anatomically. The two different systems used are illustrated in the SEER Self Instruction Manual for Tumor Registrars: Book 4. Assign the primary site code that describes the location of the tumor in the same way the tumor's location is described in the medical record.
