Behavior Code/EOD-Extension--Bladder: How are these fields coded for a bladder tumor in which the pathologist states, "there is no definite invasion identified" but the urologist states the case as T1? See Description.
Patient presents with four bladder tumors, described as "each measuring close to 2 cm." A specimen was taken of only one of the tumors. The tops of the tumors were fulgurated, then vaporized methodically. No obvious tumor or residual was noted on re-inspection.
Pathology revealed papillary urothelial carcinoma, high grade, with no definite invasion identified. Small segments of muscularis propria were present. A comment read..."it is difficult to determine if lamina propria invasion is present due to marked necrosis and tissue fragmentation." Urologist staged this as AJCC cT2a, but based on the pathology findings changed it to cT1. The urologist insists this is invasive.
For cases diagnosed 1998-2003: Because of the damage to the specimen from cautery and the insistence of the urologist that the tumor was invasive, code extension for this case to 15 based on the physician's TNM category of T1.
A T1 is invasive--code the behavior /3. The urologist is confident it is invasive, and will likely treat the patient accordingly.
Date of Diagnosis/Diagnostic Confirmation: How are these fields coded when a physician statement of diagnosis predates a positive biopsy? See Description.
A mass seen on EGD with negative biopsy 12/28/01. Needle core biopsies 1/14/02 were diagnostic of GIST. Gleevec treatment was initiated 2/02, and in discharge summary 5/27/02, the physician says the GIST was diagnosed on EGD.
Code the date of diagnosis as 01/2002. Code the diagnostic confirmation as positive histology. EGD revealed a "mass." Biopsies of the "mass" seen on EGD were negative before January 2002.
Histology (Pre-2007)--Breast: What code is used to represent the histology "ductal adenocarcinoma with medullary features?"
For tumors diagnosed prior to 2007:
Medullary is a subtype of duct and "with features of" is a term that indicates a majority of tumor. If this is an invasive adenocarcinoma with no in situ component, code to 8510/3 [Medullary adenocarcinoma]. If only one of the components is invasive, code that component.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
EOD-Extension--Kaposi Sarcoma: Is a "markedly enlarged spleen" involvement for cases of Kaposi Sarcoma?
For cases diagnosed 1998-2003: No. Splenomegaly is not synonymous with "extension to" or "involvement of" the spleen in Kaposi's sarcoma. Look for a definite statement of Kaposi's lesion(s) involving the spleen.
Radiation: How would this field be coded for treatment with quadramet [radioactive samarium]? See Description.
Paitent is receiving quadramet for treatment of lung metastases.
Code Quadramet in the RX Summ-Radiation field as 3 [Radioisotopes]. Quadramet is a radioisotope used to palliate bone pain. The instructions in the SEER manual state: "Record all radiation that is given, even if it is palliative."
Other Therapy: How do we classify "thalidomide" when it is given as cancer directed therapy?
Code to the appropriate code (1, 2 or 3) under Other Therapy, depending on whether the drug was given as part of a clinical trial. If not part of a clinical trial, assign code 1 [Other cancer-directed therapy].
Thalidomide is not FDA approved for treating cancer. It is under investigation for anti-angiogenesis effects in different cancers.
Terminology, NOS/Recurrence/Multiple Primaries (Pre-2007): Is the term "residual disease" equivalent to "recurrence"? See Description.
Example 1. Patient underwent excision and re-excision of lentigo maligna in 1998. Final path showed close but negative margins. In 1999 a biopsy of a brown patch (over the scar) in the same location was done. Pathology reported residual lentigo maligna. Is the 1999 melanoma a new primary because it was diagnosed more than two months after the first melanoma and there is no mention of recurrence? Or is the term "residual" another way of saying recurrence?
Example 2. In 1999, patient underwent excisonal biopsy of intraductal carcinoma of the right breast, followed by radiation therapy. In 2000, mammogram showed calcifications in right breast. Biopsy was done with path showing residual ductal carcinoma in situ. There is no mention of recurrence. Is this one or two primaries?
For tumors diagnosed prior to 2007:
According to our pathologist consultant, "residual" disease indicates incomplete eradication of the original disease process. Residual means that the disease process was not completely removed/eradicated in the initial therapy. Therefore cells from the original primary were never completely removed or destroyed.
In each example above, this is not a recurrence per se but rather
progression of disease. Do not abstract the latter diagnosis as a new primary.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
EOD-Size of Primary Tumor--Prostate: Is this field coded to the size of a hypoechoic mass identified on a TRUS when there is no tumor size from the prostatectomy specimen?
For cases diagnosed 1998-2003: Ultrasound measurement of a malignancy can be used to code EOD-Size of Primary Tumor. Information on tumor size taken from imaging/radiographic techniques has low priority, just above physical examination.
