Begining with cases diagnosed 2021, glomus jugulare tumor, NOS is reportable. It is listed in ICD-O-3.2 with a behavior code of /3.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

RAEB I and RAEB II [9983/3] have the same histology code per the Heme DB. They are synonyms. Per Rule M2 one abstracts a single primary when there is a single histology. There is no change to report to the state regarding histology.

The I and II designators indicate the number of blasts in the bone marrow. In RAEB, the number of blasts measures the severity of the disease and is also a predictor of the chance of a genetic transformation to AML.

In this case, the patient's disease has progressed to a more severe phase - similar to a solid tumor progressing from Stage II to Stage III.

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

Code metronomic chemotherapy as chemotherapy. Metronomic chemotherapy, also referred to as low-dose metronomic (LDM) chemotherapy, is an emerging cancer treatment approach which administers relatively low doses of traditional chemotherapy drugs over a long period of time and without ‘breaks’ in treatment. By using lower doses this method of treatment minimizes the side effects of traditional chemotherapy.

For tumors diagnosed prior to 2007:

Assign code 8244/3 [composite carcinoid] when there is a combination of adenocarcinoma and carcinoid tumor.

Assign code 8245/3 [adenocarcinoid] when the diagnosis is exactly "adenocarcinoid."

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.

For cases diagnosed 1998-2003:

Yes. Use the scheme on page 180 for MALT lymphoma. The ICD-O-2 morphology code 9715 was omitted in error. It should have been added when the EOD was printed in 1998.

The expert pathologist recommends coding histology to 8980/3 [Carcinosarcoma] for this combination histology.

Expert consultation: The designation "carcinosarcoma" is given when the pathology shows differentiation in both the sarcomatous (rhabdomyoblastic) and carcinomatous (adenoca) elements. This is emphasized in the path for this case with the term "biphasic." The term "heterologous" mean that the sarcomatous component is of a type not normal to lung. Rhabdomyoblastic means skeletal muscle differentiation. Because skeletal muscle is not normally found in lung it is heterologous. If it were smooth muscle, it would be homologous because smooth muscle is found in lung (as a part of the bronchi).

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

Code the CS Lymph Node Examined field to 98 [number unknown] because the biopsy information is not clear and as a result you do not know how many lymph nodes were examined.

Gelfoam tract embolization for a CT-guided renal biopsy is not treatment. It is a method to plug the biopsy track to reduce the risk of hemorrhage.
