EOD Fields--Lymphoma: Was MALT Lymphoma [9715/3 (ICD-O-2) and 9699/3 (ICD-O-3)] inadvertently excluded from SEER EOD manual, top of page 180?
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.
First course treatment/Chemotherapy: Is metronomic chemotherapy coded as chemotherapy?
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.
Reportability--Heme & Lymphoid Neoplasms: Does a change in the 2008 diagnosis from refractory anemia with excess blasts (RAEB I) to a subsequent diagnosis of RAEB II in 2011 need to be reported to the state if the Hematopoietic Database indicates these diagnoses represent the same primary?
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.
Reportability/Histology--Testis: Is neoplasm consistent with carcinoid type of monodermal teratoma reportable as a teratoma, NOS, and if yes, what is the histology code?
Carcinoid type of monodermal teratoma or well differentiated neuroendocrine tumor (carcinoid), monodermal teratoma of the testis is reportable. Assign 8240/3 according to the WHO classification for this neoplasm.
Histology--Heme & Lymphoid Neoplasms: Should the higher histology code associated with grade 1 follicular lymphoma [9695/3] be used rather than grade 2 follicular lymphoma [9691/3] in cases of follicular lymphoma grade 1-2?
Code histology to 9691/3 [follicular lymphoma, grade 2], histology. For follicular lymphoma, when there is a grade such as 1-2 indicated, take the histology associated with the higher grade disease process, even though the lower grade histology code is higher.
Date of Diagnosis--Colon: If a patient has a positive Cologuard test, is the date of diagnosis the date of the cologuard test or the date of the biopsy?
Do not use the date of a positive Cologuard test as the date of diagnosis.
Update to the Current Manual/SEER*RSA--SEER Site-specific Factor 1: The 2024 SEER Manual and SEER*RSA say that Codes 10-51 are hierarchical; use the highest code that applies (10 is highest, 51 is lowest). Should the guidance say that 51 is highest, 10 is lowest since code 10 is a HPV negative p16 test?
Assign the highest code with 51 as the highest and 10 the lowest when there is more than one test performed with differing results.
The SEER Manual will be updated in the 2025 release. SEER*RSA will be updated in a future release, version 3.3 in 2026, as version 3.2 has been updated for 2025.
Surgery of Primary Site--Melanoma: Please further explain the SEER Note under Melanoma surgery codes 30-36 for these two examples. Are both examples coded 31?
1. Shave bx: +melanoma in situ, +microscopic margins Wide excision: no residual melanoma in situ
2. Shave bx: melanoma, +microscopic margin Wide excision: Melanoma, margins negative (margin status negative but distance not stated)
Revised answer: Assign surgery code 30 for both examples based on the SEER Note on the top of page 2 in the Surgery of Primary Site Codes for Skin: If it is stated to be a wide excision or reexcision, but the margins are unknown, code to 30.
