Heme & Lymphoid Neoplasms: How is cancer status to be coded when a patient diagnosed with MDS, undergoes treatment, but the MDS subsequently transforms to AML?
If the bone marrow no longer shows evidence of MDS, the cancer status for the MDS is disease-free. When cancer status is coded as disease-free (NED), it means that currently there is no clinical evidence of this disease (MDS).
Grade: Can the nuclear grade value be coded in the grade field for any site, or is it restricted to sites where it is specifically listed as an option in the coding manual, i.e., breast, kidney, urinary sites, etc.?
There is no restriction on sites for which nuclear grade can be coded in the grade field. If both differentiation and nuclear grade are specified, differentiation takes priority.
Grade/Cell indicator--Lymphoma: How is Grade/Cell indicator coded for anaplastic large cell lymphoma? See Discussion.
The SPCM states cell indicator codes take precedence over grade/differentiation codes for lymphoma and leukemia cases.
For cases diagnosed prior to 1/1/2010:Because there is no cell indicator information, code 9 [cell type not determined] in the grade/cell indicator field. Do not code grade for lymphoma. For lymphoma and leukemia this field is the cell indicator.
For cases diagnosed 1/1/10 and later, 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.
Grade-Breast: How is this field coded for a breast tumor described as "intermediate nuclear grade"? See Discussion.
Guidelines for selecting grade for breast primaries prioritize nuclear grade right after B&R grade. The conversion table displays only numeric values for nuclear grade. How is grade coded for tumors in which nuclear grade is described by terminology? Does it make a difference if the tumor is invasive or in situ?
Example 1: Ductal carcinoma, intermediate nuclear grade.
Example 2: Ductal carcinoma, high nuclear grade.
Example 3: Ductal carcinoma, moderate nuclear grade.
Example 4: DCIS, intermediate nuclear grade.
Use the table on page C-607 of the 2007 SEER manual. The terms "low," "intermediate," and "high" appear in the column labeled "BR Grade." Use this column to determine the appropriate grade code when grade is described using these terms. If the grade of an in situ tumor is described using these terms, use the table to determine the appropriate code for the grade field.
Grade--Pancreas: Can the grade be coded when a biopsy is taken from the part of a primary tumor that has contiguously extended into an adjacent organ or structure? See Discussion.
The grade rule states to code grade from tissue removed from the primary tumor only, never from a metastatic site or a site of recurrence. There is no mention of whether the grade can be coded if only the contiguous site of involvement is biopsied when a single tumor directly extends to an adjacent tissue or organ. For example, is grade coded to 2 when a pancreatic tumor extends into the duodenum, and the duodenal biopsy confirms moderately differentiated adenocarcinoma consistent with a pancreatic primary? Or does the primary organ/site have to be biopsied in order to be able to code grade?
For one tumor involving a contiguous site, when there is no tissue specimen available from the primary site, you may code the grade based on the tissue from the tumor in the contiguous site.
This instruction is included in the upcoming grade instruction document.
Grade--Liver: How should grade be coded for a liver lesion treated with radio frequency ablation (RFA) followed by a transplant showing moderately differentiated hepatocellular carcinoma? See discussion.
The SEER Manual emphasizes the importance of coding grade only prior to neoadjuvant treatment as systemic treatment and radiation can alter a tumor's grade. This patient did not have neoadjuvant chemotherapy or radiation, but did undergo a prior surgical procedure (RFA) in an attempt to destroy tumor tissue. The subsequent transplant showed residual moderately differentiated HCC.
For this case, record the grade specified even though it is after RFA. RFA is not systemic or radiation treatment and should not alter the grade.
Grade--Kidney, renal pelvis: How is this field coded for a non-invasive high grade papillary urothelial carcinoma of the renal pelvis? See Discussion.
Per instructions in the 2010 SEER Manual, Appendix C, Coding Guidelines for Bladder, "Code grade 9 (unknown) for non-invasive urothelial (transitional) tumors." The Coding Guidelines listed under Renal Pelvis, Ureter are only for Kidney [C649]. Do the grade instructions under bladder apply to ALL non-invasive urothelial tumors, or are we to use the kidney grading instructions to code grade for renal pelvis and ureter malignancies?
Code grade to 4 [high grade]. Follow the instructions in the main part of the 2010 SEER Manual under the data item Grade (pages 73 - 76). There are no specific instructions for coding grade for renal pelvis. Apply the general instructions in the absence of site-specific instructions.
Grade--Heme & Lymphoid Neoplasms: Is the phrase "aberrant T-cell expression" enough to code the grade field to T-cell when the final diagnosis on the pathology report is "AML with aberrant T-cell antigen expression"?
Yes. Code grade to 5 [T-cell]. The T cell receptor, or TCR, is a molecule found on the surface of T lymphocytes (or T cells).
Grade--Heme & Lymphoid Neoplasms: How is grade coded for acute lymphoblastic leukemia, NOS? See Discussion.
The Heme DB indicates histology code 9811/3 [B lymphoblastic leukemia/lymphoma] is the current histology code to use for the now obsolete term of acute lymphoblastic leukemia [9835/3]. The Heme DB entry for histology code 9835/3 states to "Code grade specified by pathologist. If no grade specified, code 9." The Heme DB entry for the current histology code, 9811/3, states to code the grade to 6 [B-cell]. Should grade be coded to 6 [B-cell] for all cases coded to histology code 9811/3?
Code the grade to 6 [B-cell] for all cases of 9811/3 [B lymphoblastic leukemia/lymphoma] per Rule G3 in the Heme Manual.
Acute lymphoblastic leukemia, NOS [9835/3] is an obsolete code and cannot be used for cases diagnosed 2010 and later. The Heme DB indicates the correct histology code is 9811/3 and grade 6 [B-cell] for cases diagnosed 2010 and later.
For cases of acute lymphoblastic lymphoma, NOS [9835/3] diagnosed prior to 2010, use the pathology report information to code the grade. Code the grade as 9 [unknown] if the pathology report does not specify the grade.
