Multiple primaries--Heme & Lymphoid Neoplasms: Could you please clarify Note 2 found in Rule M10, which is " 'Transformations to' (acute neoplasms) and 'Transformations from' (chronic neoplasms) are defined for each applicable histology in the database." Do the neoplasms being considered have to contain the words 'chronic' and/or 'acute'?
Hematopoietic neoplasms that transform generally don't have 'chronic' or 'acute' as part of their preferred name. The 'chronic' and 'acute' designations are determined by the usual course of the neoplasm. Chronic neoplasms are generally slow growing while acute neoplasms grow fast and are more widespread. Not all Hematopoietic neoplasms transform. Each neoplasm that has the ability to transform has the transformations listed under the 'Transformations to' and/or 'Transformation from' sections in the Hematopoietic database.
For example, Diffuse large B-cell lymphoma (histology code 9680/3) has no histologies/neoplasms listed under 'transformations to.' This means that this neoplasm does not transform to any other neoplasm. There are multiple histologies/neoplasms listed under 'Transformations from' indicating the neoplasms listed under the Transformations from are the chronic neoplasms, and DLBCL is the acute neoplasm. If DLBCL (9680/3) occurs at the same time, within 21 days, or greater than 21 days of any of the histologies listed under 'Transformations From,' rules M8-M13 apply. If DLBCL (9680/3) occurred at the same time as a neoplasm not listed in the Transformations sections, the acute and chronic rules do not apply.
CS Extension--Breast: Is the term "erosion" the same as "ulceration"?
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.
"Erosion" is not synonymous with "ulceration" when coding CS extension for breast.
Solid Tumor Rules (2018)/Histology--Lung: If the pathology states non-small cell carcinoma of the lung (NSCLC), consistent with squamous cell carcinoma, is the code non-small cell carcinoma according to the Solid Tumor Rules? The Medical Oncologist states that the tumor is a squamous cell carcinoma. In these instances would you code the squamous cell carcinoma since you have a definite physician statement?
Code the histology to SCC 8070/3.
Based on registrar feedback on the NSCLC rule, we added a rule that specifically addresses when ambiguous terminology can be used to code histology other than NSCLC. The lung rules were update 10/12/2018 so please make sure you are using the currently posted rules. The new rule is: Rule H3-Code the specific histology when the diagnosis is non-small cell lung carcinoma (NSCLC) consistent with (or any other ambiguous term) a specific carcinoma (such as adenocarcinoma, squamous cell carcinoma, etc.) when:
* Clinically confirmed by a physician (attending, pathologist, oncologist, pulmonologist, etc.)
* Patient is treated for the histology described by an ambiguous term
* The case is accessioned (added to your database) based on ambiguous terminology and no other histology information is available/documented
Example 1: The pathology diagnosis is NSCLC consistent with adenocarcinoma. The oncology consult says the patient has adenocarcinoma of the right lung. This is clinical confirmation of the diagnosis, code adenocarcinoma.
CS Site Specific Factor--Breast: If the tumor is described as being a 1 cm poorly differentiated pleomorphic lobular carcinoma with scattered LCIS in breast tissue, for SSF6, do we use the breast tumor or all of the breast tissue removed when coding SSF6?
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.
Site Specific Factor 6 in the breast scheme describes the relationship of invasive and in situ tumor in the tumor size coded. Code SSF6 for the same tumor used to code tumor size.
For this example, code SSF6 for the 1 cm tumor. In this case, the entire tumor is reported as invasive; use code 000 [Entire tumor reported as invasive].
Reportability--Ovary: Is a Stage IIIC serous borderline tumor (micropapillary type) of the ovary diagnosed in 2003 reportable?
Serous borderline tumor of the ovary diagnosed in 2003 is not reportable to SEER. The behavior code is /1 in ICD-O-3. The high stage does not make this borderline tumor reportable.
Histology (Pre-2007): What code is used to represent the histology "poorly differentiated invasive transitional cell carcinoma with extensive squamous and focal glandular differentiation"?
For tumors diagnosed prior to 2007:
Code the Histology field to 8120/33 [transitional cell carcinoma, NOS, poorly differentiated]. The ICD-O-3 does not have a separate code for transitional cell carcinoma with squamous and/or glandular differentiation.
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.
Histology (Pre-2007)--Lung: How is a poorly differentiated non-small cell carcinoma with "squamoid differentiation" coded?
For tumors diagnosed prior to 2007:
Squamoid and squamous are synonymous. Squamoid is non-standard terminology. It means "squamous like" and is a synonym of squamous.
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.
First Course of Treatment/Surgery of Primary Site--Melanoma: How do you code UVB therapy treatment for melanoma?
Code UVB therapy for melanoma as photodynamic therapy under Surgery of Primary Site for skin. Assign code 11 [Photodynamic therapy (PDT)] if there is no pathology specimen. Assign code 21 [Photodynamic therapy (PDT)] if there is a pathology specimen. Use text fields to document details.
CS Site Specific Factor--Lymphoma: Can the International Prognostic Index (IPI) score be taken from a TNM form in the record? If so, what score would we code for "low" (0-1 points) and "high" (4-5 points)?
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.Yes, the IPI score from the TNM form can be used to code SSF 3. Without further information, code "low" as 000 [0 points]. Code "high" as 004 [4 points].
