EOD-Extension--Lymphoma: How do you code stage and EOD for an extranodal lymphoma with bilateral involvement of a paired site? See discussion.
For example, we frequently see cases of lymphoma occurring in bilateral orbits, or both lungs. This issue was discussed at a 1991 SEER meeting with the tentative answer being that lymphoma involving both organs of a paired site will be coded as stage I (e.g., both eyes or both lungs), as this would be contiguous disease. However, an extranodal lymphoma involving tissue of both limbs (e.g., soft tissue of both arms) will be coded as stage IV because this represents wide areas of involvement that have no connection.
For cases diagnosed 1998-2003:
Bilateral involvement of an extralymphatic paired organ is coded as involvement of a single extralymphatic organ or site for lymphomas. The EOD extension code would be at least 11 (Stage IE). Staging lymphomas of any site depends on whether one or more lymph node regions and/or extralymphatic organs are involved, and whether sites on one or both sides of the diaphragm are involved.
Grade, Differentiation--All Sites: Should we take the grade from a TNM staging form over a grade stated in a pathology report when the grade mentioned on the TNM staging form is a higher grade (e.g., Pathology report diagnosis is moderately differentiated adenocarcinoma, Gleason's 3+3=6, but the physician checked "poorly differentiated" on the TNM form)?
Code the Grade, Differentiation field to 2 [moderatley differentiated]. Code from the pathology report over the TNM staging form. If you do not have access to the path report, use the grade from the TNM form.
Histology (Pre-2007)/EOD-Lymph Nodes/SEER Summary Stage 2000--Breast: What codes are used to represent these fields for a breast case with a diagnosis of ductal carcinoma in situ and a positive regional lymph node?
For tumors diagnosed prior to 2007:
Code the Histology field to 8500/3 [Infiltrating duct carcinoma, NOS]. Code the EOD-Lymph Nodes field to 6 [Axillary/regional lymph nodes, NOS] and the SEER Summary Stage 2000 field to 3 [Ipsilateral regional lymph nodes(s) involved only].
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.
1) If Van Nuys nuclear grade 2 is the only grade given for an in situ breast primary, would it be coded as a 3-component system (e.g., 2/3 = 3)?
2) Is there a way of determining grade if only the total Van Nuys Prognostic index score is given (e.g., score 7/9)?
1. Code Van Nuys grade 2 as code 2 [Grade 2] in the Grade, Differentiation field.
2. Code Van Nuys score of 7 as 9 [Cell type not determined, not stated or not applicable] in the Grade, Differentiation field.
Currently, there is no conversion from the total Van Nuys score to grade because "grade" represents only one of the three Van Nuys factors that make up the total score. The other factors are tumor size and margin. The grade represents from 1 to 3 points within the total Van Nuys score. The total score can be between 3 and 9.
Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 3 [Number of regional lymph nodes removed unknown or not stated; regional lymph nodes removed, NOS] and code the EOD-Number of Regional Nodes Examined field to 00 [No nodes examined].
The surgery fields reflect the procedures the physician performed. The EOD fields reflect the results of those procedures.
Multiple Primaries (Pre-2007)--Skin: If a patient presents with two separate lesions on the left cheek (i.e., left lateral cheek and left upper cheek) that both are histologically confirmed to be superficial spreading melanoma on the same day, is this coded as one or two primaries?
For tumors diagnosed prior to 2007:
Code as one primary.
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.
Reportability/Ambiguous Terminology/Date of Diagnosis: If a "suspicious" cytology is reportable only when a later positive biopsy or a physician's clinical impression of cancer supports the cytology findings, is the Date of Diagnosis field coded to the later confirmation date rather than to the date of the suspicious cytology? Is a suspicious "biopsy" handled the same way?
Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.
Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.
Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.
Reportability--Hematopoietic, NOS: Is the term "plasma cell dyscrasia" a synonym for multiple myeloma?
For cases diagnosed prior to 1/1/2010:
Plasma cell dyscrasia, NOS, is nonreportable. It is not a synonym for multiple myeloma. Plasma cell dyscrasia represents a broad spectrum of disease characterized by plasma cell proliferation that appears inappropriate or uncontrolled. Multiple myeloma is one disease type that falls into that classification. However, there are several other malignant and benign diseases also classified as such because of their immunoglobulin abnormalities. Reportability to SEER regarding a disease classified as a plasma cell dyscrasia is dependent on identifying the specific cell type associated with the disease in the ICD-O-3.
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.
Reportability--Myelodysplastic Syndrome: How we handle cases of myelodysplastic syndromes identified in 2001 casefinding documents that are determined to have an "unknown diagnosis" date after review of the patient's hospital medical record?
Myelodysplastic syndrome cases with unknown dates of diagnosis identified in pre-2001 casefinding documents should not be accessioned and are not SEER reportable.
For cases identified in 2001 casefinding documents, when the diagnosis date cannot be confirmed using the medical records typically accessed by the registrar or central registry staff, do not accession these cases; they are not SEER reportable. This default applies only to those cases identified in 2001 casefinding documents.
For cases identified in 2002 or later casefinding documents, the attending physician should be contacted and asked to clarify the diagnosis date for cases identified with unknown dates of diagnosis. Clarifying the diagnosis date is necessary to determine whether the case is reportable and whether it should be accessioned.
