Multiple Primaries (Pre-2007)--Thyroid: Would a papillary carcinoma of the right lobe of the thyroid diagnosed approximately 2 1/2 years after a papillary carcinoma of the left lobe be coded as a second primary? See Description.
8/31/1999: papillary carcinoma, left lobe thyroid, treated with lobectomy.
1/17/2002: papillary carcinoma, right lobe, treated with lobectomy, completion thyroidectomy.
For tumors diagnosed prior to 2007:
Yes, this is a second primary. The second papillary carcinoma was more than 2 months after the first and not specified as recurrent or metastatic.
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-Pathology Extension--Prostate: Is extracapsular extension implied by the phrase, "involvement of periurethral or urethral margins"? See Description.
The prostatectomy final pathology diagnosis states that the tumor involves the periurethral margin. The microscopic describes involvement of the urethral margin.
For cases diagnosed 1998-2003: Code the EOD-Extension field in the 20-34 range, which implies no extension beyond the prostate. Disregard involvement of periurethral margin or urethral margin, NOS, unless the pathologist or surgeon specifically mentions "extraprostatic urethra" involvement.
Primary Site/Histology (Pre-2007)--Unknown & ill-defined site: How are these fields coded for a markedly atypical high grade malignant neoplasm diagnosed by a fine needle aspiration of a large iliac mass, right buttock area? See Description.
The diagnosis was made in Oct. 2002 by a CT guided fine needle aspiration of a large iliac mass, right buttock area. The cytology report says:
a. positive for malignant cells, markedly atypical high grade malignant neoplasm.
b. It is impossible to tell from this aspiration biopsy whether or not this represents a high grade sarcoma or a high grade carcinoma, but our consensus opinion is that this lesion is a high grade carcinoma.
The combination of soft tissue topography and carcinoma morphology is Impossible by SEER edits. How should we code this?
For tumors diagnosed prior to 2007:
Code the site to C76.3 [Pelvis, NOS]. Code the histology to 8010/34 [Carcinoma, NOS, high grade].
Unless there is better information available regarding the site, assign C76.3. The information provided above does not indicate the exact site of the mass.
Code the histology based on the consensus opinion stated above.
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.
Reportability: Is pseudomyxoma peritonei always reportable? See Description.
In the ICD-O-3, pseudomyxoma peritonei has a behavior code of 6, indicating that it is malignant. Does this imply that pseudomyxoma peritonei is always a reportable malignancy? In the past, our pathologist consultant told us that pseudomyxoma peritonei is only a reportable malignancy if the underlying tumor is malignant. A benign cystadenoma of the appendix, for example, can rupture causing pseudomyxoma perionei. Does SEER agree with our pathologist consultant?
Example: Patient was found to have psuedomyxoma peritonei. Right hemicolectomy was done. Path reported an appendix with mucinous cystic tumor of undetermined malignant potential. A definite diagnosis of cancer can not be rendered.
Reportability is determined from the behavior of the primary tumor and the behavior of implants. If either are malignant, the case is reportable.
The case example does not seem to be reportable, based on the available information. Cancer diagnosis has not been made according to the pathology report.
Other Therapy/Immunotherapy--Hematopoietic, NOS: How should erythropoietin be coded for leukemia or other hematopoietic diseases?
Do not code Erythropoietin as treatment, it is used as an ancillary drug for leukemias or other hematopoietic diseases. Record information about erythropoietin in the text field.
EOD-Size of Primary Tumor--Breast: How do we code this field when there is a difference between the size of the tumor mentioned in the gross (i.e., macroscopic description) and the comment sections of a pathology report? See Description.
Path Macro Summary states size as 1.5 cm. The path comment states "largest area of tumor seen is 1.5 cm. However, 8 of the nearly contiguous sections are involved with an estimated 2.4 cm area of involvement."
For cases diagnosed 1998-2003: Code the size of the largest area of tumor from the path macro summary. For the example provided, code the size as 015 [1.5 cm]. In this case, the additional sections of tumor described in the path comment do not seem to represent pieces of one larger tumor. The 2.4 cm estimated area of involvement was determined by adding together noncontiguous tumor sections. According to the CAP protocol for breast, Note J "When 2 or more distinct invasive tumors are present, each is separately measured...they are not combined into a single larger size."
Histology (Pre-2007)/Primary Site/Diagnostic Confirmation: How would these fields be coded for a diagnosis of cholangiocarcinoma based on clinical findings only? See Discussion.
We have a case of reported "cholangiocarcinoma" of the liver diagnosed only by a CT of the abdomen. There is no pathologic confirmation. CT ABD: Heterogeneous liver mass suspicious for cholangiocarcinoma; mass causes right portal & right hepatic vein occlusion & right and left biliary duct dilatation....
Should this be coded to cholangiocarcinoma by radiology alone and should it be liver as primary site?
For tumors diagnosed prior to 2007:
Code according to the prevailing medical opinion in this case. If no further information can be obtained, code as cholangiocarcinoma of the intrahepatic bile duct.
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/EOD-Lymph Nodes--Cervix: How do you code these fields when the cancer extended to the pelvic wall and there are periaortic LN metastases?
For cases diagnosed 1998-2003:
Assign extension code 65 for contiguous (direct) extension of tumor from the cervix to the pelvic wall. Assign extension code 85 only if the pelvic wall is involved with discontinuous extension from the cervix; i.e., the cervical tumor spread indirectly (through lymph or vascular channels) to the pelvic wall. Code the pelvic wall involvement in the Extension field and the periaortic lymph node involvement in the Lymph Node field. When the computer does the algorithm, it will look at the periaortic lymph nodes and report the summary stage as distant and the TNM stage group as IV because periarotic nodes are M1. Do not code the periaortic lymph nodes in both fields. This is stage IV, distant disease, due to the periaortic lymph node involvement (EOD lymph nodes code 6).
EOD-Extension--Head & Neck (Uvula): Is a stage T2 tumor described on the physical exam as an "ulcerated mass occupying uvula midline soft palate, and extending into the right soft palate. It does not extend into the tonsil area nor into the retromolar trigone" coded to 30 [localized, NOS] or 40 [tumor crosses midline]?
For cases diagnosed 1998-2003:
Code EOD-extension to 30 [localized, NOS]. This is mucosal spread (since there is no muscle in the uvula). Soft palate and uvula are handled as a single site, and extension from uvula to soft palate is not addressed in EOD.
