EOD-Pathology Extension--Prostate: Is extracapsular extension implied by the phrase, "involvement of periurethral or urethral margins"? See Description.
The prostatectomy final pathology diagnosis states that the tumor involves the periurethral margin. The microscopic describes involvement of the urethral margin.
For cases diagnosed 1998-2003: Code the EOD-Extension field in the 20-34 range, which implies no extension beyond the prostate. Disregard involvement of periurethral margin or urethral margin, NOS, unless the pathologist or surgeon specifically mentions "extraprostatic urethra" involvement.
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.
Multiple Primaries (Pre-2007)--Kidney: How many primaries are reportable in a patient treated with a bilateral nephrectomy that revealed multiple tumors within each kidney and the histology in both the left and the right kidney was "renal cell carcinoma, indeterminate type: multiple histologically identical tumors" and the clinical discharge diagnosis was "bilateral renal cell carcinoma, probably surgically cured"? See discussion.
The SEER manual states "If only one histologic type is reported and if both sides of a paired site are involved within two months of diagnosis, a determination must be made as to whether the patient has one or two independent primaries." Frequently, the only statement we have is that "bilateral organs are involved." Additional guidelines for determining number of primaries would be helpful.
For tumors diagnosed prior to 2007:
Report this case as two primaries, left and right kidneys. According to our pathologist consultant, "The description sounds like bilateral multiple primaries. Multicentricity in the same kidney occurs in about 4% of all cases, and bilaterality in 0.5 to 3% (Atlas of Tumor Pathology, Tumors of the Kidney, Bladder, and Related Urinary Structures)."
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.
MP/H Rules/Histology--Prostate: While cases of "acinar adenocarcinoma" of the prostate are required to be abstracted with the histology code 8140/3 [adenocarcinoma, NOS] for cases diagnosed 1/1/07 or later, can 8550/3 [acinar adenocarcinoma] be used for cases diagnosed prior to 1/1/07? See Discussion.
The SEER Multiple Primary and Histology manual, effective with 2007 forward diagnosis dates, indicates that this histology should be coded to 8140/3 [adenocarcinoma, NOS]. Does this contradict ICD-O-3? Can acinar adenocarcinoma be coded for other primary sites?
For cases diagnosed 2007 or later, code acinar adenocarcinoma of the prostate as 8140/3.
Prior to diagnosis year 2007, code 8550/3 [acinar adenocarcinoma] may be used for prostate cases and for acinar adenocarcinoma of other sites, such as pancreas.
Behavior--Bladder: What behavior code is used for a TURB path specimen diagnosis of "non-invasive urothelial carcinoma, no muscle found, depth of invasion cannot be assessed" when the clinician stages the case as Ta? See Discussion.
The SEER site specific coding module for bladder says, "If the only surgery performed is a TURB and if it is documented that depth of invasion cannot be measured because there is no muscle in the specimen, code the behavior as malignant and not in situ."
Assign behavior code 2 [in situ] based on the physician's stage Ta.
When no other information is available and the TNM designation is not available, use the instructions on page C-844 in Appendix C of the 2007 SEER manual as a default.
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.
CS Tumor Size--Ovary: The size of a cyst is not coded in this field. However, can the size of a "cystic mass" be coded in this field? See Discussion.
The specimen consists of a cystic mass which weighs 1520 grams and measures 23 x 17 x 10 cm.
If the tumor is described as a "cystic mass" and only the size of the entire mass is given, code the size of the entire mass, because the cysts are part of the tumor itself.
Please note: Ovarian cancer stage is not based on tumor size.
CS Extension--Pancreas: How do you code this field for a head of pancreas primary with involvement of portal and splenic veins? See Discussion.
The splenic artery/vein is only mentioned in the body and tail scheme; no mention is made of this site in the pancreatic head scheme.
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.Assign CS extension code 54 [major blood vessels]. The portal vein is listed under code 54 for head of pancreas. The splenic vein branches from the portal vein.
EOD-Pathologic Extension--Prostate: Can a pathological extension code be assigned when a retropubic prostatectomy is done? See discussion.
The TNM manual states, "Total prostatoseminalvesiculectomy and pelvic lymph node dissection are required for pathologic staging."
For cases diagnosed 1998-2003:
The pathology report from a retropubic prostatectomy should be used to code the Pathologic Extension field. This field is coded using pathology report information from the prostatectomy operation regardless of the surgical approach and regardless of whether or not a pelvic lymph node dissection was performed. This is one area in which TNM rules for pathologic staging and SEER rules for EOD are slightly different.
Primary site/Histology: Does SEER accept the site/type combination of lymph nodes (C77.0-C77.9) with the histology of either 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) or 9827 (Adult T-cell leukemia/lymphoma)? See Discussion.
There is a discrepancy between the SEER Site/Type table and the CS histology codes under Lymph Nodes.
For cases diagnosed prior to 1/1/2010:These are not "impossible" site/histology edits. You can override them. However, if the lymph nodes are involved and a lymphoma histology is available, the lymphoma histology should be coded rather than leukemia histology. For example, assign histology code 9670 (Malignant lymphoma, small B lymphocytic, NOS) instead of 9823 (B-cell chronic lymphocytic leukemia/small cell lymphocytic lymphoma) if the disease is identified in the lymph nodes.
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.
