Immunotherapy/Chemotherapy: Are monoclonal antibodies, such as Avastin and Erbitux, coded as immunotherapy or chemotherapy? See Discussion.
In review of the "FDA-approved oncology agents not listed in SEER Book 8" provided in 5/02, it appears "monoclonal antibodies" are coded as immunotherapy.
Code Avastin and Erbitux as chemotherapy because both of these drugs are growth inhibitors. Code growth inhibitors (cytostatic agents) as chemotherapy. Do not assume that monoclonal antibodies are coded as immunotherapy.

Scope of Regional Lymph Node Surgery/Radiation Sequence with Surgery/Date Therapy Initiated: Is the Scope of Regional Lymph Node Surgery field used to code date of first therapy and radiation sequence with surgery? See discussion.
Example: There is no primary site surgery and only an aspirate of a lymph node and the date of therapy is based on this procedure.
Yes, the Scope of Regional Lymph Node Surgery field is used to code the Date Therapy Initiated field and the Radiation Sequence with Surgery field.

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.
