Multiple Primaries (Pre-2007)--Bladder/Prostatic Urethra: Is the prostatic urethra a new primary for a case with a history of recurrent noninvasive bladder cancer that was subsequently diagnosed with transitional cell carcinoma in situ of the prostatic urethra and had a subsequent clinical diagnosis of "refractory bladder carcinoma"?
For tumors diagnosed prior to 2007:
If the histology of the bladder primary is "transitional cell carcinoma" or "papillary transitional cell carcinoma," do not code the prostatic urethra as a new primary. This is probably a case of intraluminal (mucosal) spread of the original tumor, rather than separate primaries. The clinical diagnosis supports this view.
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.
Recurrence (Pre-2007)--Colon: When there is no statement of recurrence on the abstract, is a colon tumor at the anastomosis site a recurrence of the previous colon cancer or a new primary?
For tumors diagnosed prior to 2007:
If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.
If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate 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.
Primary Site: Can we assume the primary site for "chordoma" is soft tissue if the bone is not stated to be involved?
Default the coding of the Primary Site field for chordomas to the bone where the tumor began in the body if the primary site is not clearly stated to be soft tissue. Bone is often the primary site for chordomas.
Based on advice from pathologist consultants: This is one of those situations where we can be quite comfortable with a default, in this case to bone, not soft tissue. Chordoma is a tumor arising in the nucleus pulposis, presumably from remnants of notochord - thus its exclusive origin is in the sacrococcygeal region, spheno-occipital region, and vertebral bodies, otherwise known collectively as the axial skeleton. Any "chordoma" in soft tissue (with no relationship to axial skeleton) is probably a myxoid chondrosarcoma or parachordoma (extremely rare).
Histology: What code is used to represent the histology "endometrioid adenocarcinoma, villoglandular type"?
Assign code 8262/3 [Villous adenocarcinoma].
According to the WHO Classification of Tumours, Breast and Female Genital Organs (2003), villoglandular is one of four variants of endometroid adenocarcinoma. The corresponding ICD-O-3 code according to WHO is 8262/3.
Reportability/Ambiguous Terminology/Date of Diagnosis: If a "suspicious" cytology is reportable only when a later positive biopsy or a physician's clinical impression of cancer supports the cytology findings, is the Date of Diagnosis field coded to the later confirmation date rather than to the date of the suspicious cytology? Is a suspicious "biopsy" handled the same way?
Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.
Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.
Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.
Histology (Pre-2007): What code should be assigned to acinar adenocarcinoma and ductal adenocarcinoma?
For tumors diagnosed prior to 2007:
Assign code 8255 [Adenocarcinoma with mixed subtypes]. According to histology rule #4 for a single tumor on page 86 of the 2004 SEER manual, use a combination code if one exists.
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-Clinical Extension--Prostate: Must all three criteria be met (an elevated PSA; documentation that the physical exam was negative; and, if a TRUS was done, there is documentation that the findings were negative) in order to code this field to 15 [Tumor identified by needle by elevated PSA]?
For cases diagnosed 1998-2003:
Refer to the Prostate EOD Coding Guidelines, Final version distributed to SEER Registries 6/20/2001.
Prostate clinical EOD extension code 15 is used when all three criteria are met as listed on page 3 of the Prostate EOD Coding Guidelines. Meeting 1 or 2 of the 3 criteria is not sufficient for code 15. PE must be done and documented as negative. TRUS may or may not be done, but if done, must be documented as negative. PSA must either be elevated or there is no documentation about the PSA.
Codes 20 and 23-24 would be used with positive physical exam or positive TRUS.
Use codes 30-34 when there is no documentation that the physical exam was negative, or no documentation that the TRUS was negative, or when the prostatic apex is involved.
Ambiguous Terminology/Reportability: Is the phrase "indicative of cancer" SEER reportable?
No. The phrase "indicative of cancer" alone is not a definitive cancer diagnosis. The word "indicative" is not on the list of ambiguous terms that is equivalent to a diagnosis of cancer.
Reportability: When a biopsy is suspicious for cancer and re-biopsy is negative, is reportability based on the clinician's judgement (cancer vs NED)?
If the re-biopsy was done because the first biopsy was inconclusive, do not report this case. If the re-biopsy was more complete, or performed in an attempt to gain a wider margin, this case is reportable based on the first biopsy.
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.
