Radiation: Is "consolidated" radiation therapy coded as part of first course therapy when there is no documentation of "planned treatment" and the radiation is done 4 months after the initiation of treatment?
Yes, "consolidation" treatment is part of a planned treatment regimen. A treatment regimen may consist of the four following phases:
Grade, Differentiation--Lymphoma/Leukemia: What code is used to represent this field for a lymph node biopsy that reveals "well differentiated lymphocytic lymphoma" and a bone marrow biopsy that reveals "chronic lymphocytic leukemia/well differentiated lymphocytic lymphoma"?
For cases diagnosed prior to 1/1/2010:
Code the Grade, Differentiation field to 1 [Grade 1] for both of these cases because there is no mention of T-cell, B-cell, null cell, or NK cell involvement. Both cases have a pathologic description of well differentiated, not the descriptors "high grade," "low grade," or "intermediate grade" which must be ignored when coding grade for lymphomas.
For lymphomas, you cannot code the descriptions "high grade," "low grade," and "intermediate grade" in the Grade, Differentiation field because these terms refer to categories in the Working Formulation and not to histologic grade. However, you can code terms such as "well differentiated", "moderately differentiated" and "poorly differentiated" for lymphoma histologies.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
CS Tumor Size/CS Site Specific Factor--Breast: How do you code the CS Tumor size and SSF6 fields for a breast cancer described as "Paget disease with underlying intraductal carcinoma (4cm x 3.2cm)"?
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.CS Tumor Size: Assign code 040 for tumor size and code SSF6 as 050 [Invasive and in situ components present, size of entire tumor coded in CS TS]. The size of the invasive component is not stated AND proportions of in situ and invasive are not known.
Primary site: If text supports a pancreatobiliary primary with no other information what primary site code would be assigned? C249 biliary tract NOS, or C269 GI tract nos, or C809 unknown?
Assign C269 in the absence of any additional information.
MP/H Rules/Histology--Head and Neck: What is the histology code for salivary duct carcinoma of parotid gland?
Code salivary duct carcinoma to invasive ductal carcinoma (8500/3). Salivary duct carcinoma is an aggressive adenocarcinoma which resembles high-grade breast ductal carcinoma according to the WHO Classification of Tumors of Head & Neck.
CS Tumor Size--Lung: If a 5/11/07 CT showed a 6.5 cm LLL mass and a 7/24/07 CT showed 8.4 cm LLL mass, do we code the larger tumor size identified within four months of diagnosis or do we code the first size documented at the time of diagnosis?
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 larger tumor size.
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.
Reportability/Histology--Anal Canal: For cases diagnosed in 2021, is anal intraepithelial neoplasia (AIN) II reportable? There is conflicting information regarding the reportability for AIN II. SINQ 20210048 says to report AIN II but the 2021 SEER Manual Appendix E states intraepithelial neoplasia (8077/2 and 8148/2) must be unequivocally stated as grade III to be reportable.
AIN II is reportable for 2021. Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable for cases diagnosed in 2021. AIN is a type of squamous intraepithelial neoplasia.
The wording in Appendix E of the 2021 SEER manual (must be unequivocally stated as grade III to be reportable) was left over from earlier versions and is not correct for 2021 diagnoses. Follow the guidance in SINQ 20210048.
EOD-Size of Primary Tumor--Lung: Can tumor size of 002 [Malignant cells present in bronchopulmonary secretions] be used when there is a lung mass seen but the diagnosis is from a positive bronchopulmonary secretion?
For cases diagnosed 1998-2003:
EOD-Size of Primary Tumor code 002 [Malignant cells present in bronchopulmonary secretions] is used only when there is no visible primary lung tumor and bronchopulmonary secretions are positive for lung malignancy.
Even if the diagnosis was made by cytology of broncho-pulmonary secretions, if there is a visible mass, code the size of the mass if known, code 999 if size is unknown.
Primary Site: Is an "angiosarcoma" stated as arising in the skin of the breast and treated with a mastectomy, coded to the primary site of skin or breast?
Code the primary site as skin of breast when skin of breast is documented as the site of origin.
According to the WHO classification of soft tissue tumors, the majority of angiosarcomas "develop as cutaneous tumors...less than one quarter present as a deep soft tissue mass."
