Grade, Differentiation--Prostate: Has SEER officially changed the conversion code for Gleason score 7 to grade 3 [poorly differentiated] for cases diagnosed in 2003 or later?
For prostate cases diagnosed in 2003 and forward: convert Gleason score 7 to grade 3 [poorly differentiated].
Histology--Heme & Lymphoid Neoplasms: How is histology coded for a pathologic diagnosis of "B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and Burkitt lymphoma" that was clinically referred to as a "double hit lymphoma"?
Code histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Per the Alternate Names section in the Heme DB, B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is one of the synonyms for for DLBCL.

Primary Site/EOD-Extension--Kaposi Sarcoma: How are these fields coded for localized disease described as "Nodal Kaposi Sarcoma" found on inguinal node biopsy only?
Code the site of involvement as the primary site when no other involvement is documented. For the case above, code C774 [inguinal lymph node] as primary site.
For cases diagnosed 1998-2003: Code EOD-extension as 13 [Visceral].
First Course Treatment--Prostatic Urethra: Is Lupron coded for a papillary carcinoma of the prostatic urethra that is treated with a TUR with fulguration and beam radiation even though the prostate biopsies are negative?
Do not code lupron as treatment for a primary in the prostatic urethra.
Reportability--Ovary: Is immature teratoma of the ovary reportable if a subsequent comment states that "the teratoma shows immature neuroepithelium, but no malignant elements"?
There is conflicting information for this case. The final diagnosis conflicts with the comment. Go back and check with the physician to clarify his/her intent. If no further information can be obtained, the final diagnosis is preferred over the comment. This case is reportable based on the final diagnosis: "immature teratoma."
Primary site--Heme & Lymphoid Neoplasms: Is a peripheral blood equivalent to bone marrow biopsy for the purposes of Rule PH26 and code the primary site to C421 [Bone marrow] for a marginal zone lymphoma found in peripheral blood when there was no additional workup (e.g., scans, etc.) for this case?
Code the primary site to C421 [bone marrow]. Our hematopoietic specialty physicians state that involvement of peripheral blood is equivalent to bone marrow involvement because the marrow produces blood. In the absence of any other involvement, per Module 7 (Coding primary sites for lymphomas) Rule PH26, it states to code the primary site to bone marrow when the only involvement is bone marrow.

Tumor Size--Pathologic--Anus: In 2019, the pathology report of an anal canal squamous cell carcinoma stated the tumor size is 2.5 cm from proximal to distal (3.5 cm in circumference). Is the pathologic tumor size tumor size 025 or 035?
Based on the information provided, code the tumor size as 035. We asked an expert pathologist to review this question and she said to use the larger measurement. She also said "the pathologist usually cuts the anus and rectum open like a tube; the “circumference” would be measured flat."
Primary Site: How is this field coded for cholangiocarcinoma involving the intrapancreatic bile duct?
Code the primary site as C24.0 [Extrahepatic bile duct, includes Common bile duct] for a cholagiocarcinoma originating in the common bile duct. A portion of the common bile duct is within the head of the pancreas: The intrapancreatic segment of the common bile duct.
Primary site/Histology--Heme & Lymphoid Neoplasms: Should the primary site and histology codes be updated when a patient with a history in 2005 of a bone marrow diagnosis of chronic lymphocytic leukemia later presents in 2010 with lymph node biopsy diagnosis of small B-cell lymphocytic leukemia?
Per Rule M2, this is a single primary because there is a single histology. Code histology to 9823/3 [CLL/SLL]/
The distinction of CLL vs. SLL cannot be made on bone marrow biopsy in isolation. The pathologist cannot make a diagnosis of CLL vs SLL without having peripheral blood counts available for review. If the patient was treated for CLL in the past, that may alter the peripheral counts seen in 2010 (e.g., lymphocytosis). The distinguishing feature is peripheral lymphocytosis in CLL (not seen in SLL). The disease looks the same and both will often have bone marrow involvement and lymph node involvement. If the patient had true CLL in 2005, then any subsequent lymph node (or other) biopsy consistent with CLL/SLL remains consistent with the original diagnosis of CLL. I would not change the original CLL code.
I agree with the previous response. We have to assume the 2005 diagnosis included a peripheral blood supporting that diagnosis. Otherwise, CLL and SLL look the same in nodes and marrow. The interplay between the two "diseases" is expected. This is why they are considered a single disease.
