CS Extension--Lymphoma: If bilateral tonsils are involved with lymphoma, is it one or two regions of involvement and how is extension coded?
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.For cases diagnosed 1-1-08 and later: Assign CS extension code 10 [involvement of a single lymph node region]. Bilateral tonsils are one organ/site.
See Note 1 under CS Extension. Tonsil is coded the same as a lymph node region.
Histology (Pre-2007)--Melanoma: Is the code 8740/3 [malignant melanoma in a junctional nevus] to be used when the pathologic diagnosis is "malignant melanoma arising in a compound nevus"?
For tumors diagnosed prior to 2007:
Assign code 8720/3 [malignant melanoma, NOS] for malignant melanoma arising in a compound nevus. A compound nevus is not the same as a junctional nevus.
ICD-O-3 does not have a specific code for melanoma in a compound nevus. Assign the code for the type of melanoma specified; for example, NOS, superficial spreading, etc.
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.
CS Extension--Lung: If only a "single" cytology is performed on pericardial fluid and it is negative, can Note 6 B, which states that pleural effusion [code 72] is coded as malignant unless there are "multiple" negative cytologies, be used to infer that the pericardial fluid should also be coded as involvement?
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.
No, do not apply the instructions for pleural effusion to pericardial effusion. Do not code a pericardial effusion proven negative by cytology in CS Extension.
CS Extension/CS Mets: For primary sites within the peritoneum (abdominalpelvic walls) such as stomach, colon, does the presence of malignant ascites affect the coding of CS Extension or CS Mets?
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.
The Collaborative Staging system is governed by site-specific coding rules. Refer to each set of site rules rather than looking for a general answer for all sites in peritoneum. In particular, Ovary and Corpus allow malignant ascites to be coded in CS Extension, but not CS Mets at Dx. For each site, both CS Extension and CS Mets at Dx should be checked for the proper field to code malignant ascites.
Reportability--Hematopoietic, NOS: Is a "Myelodysplasia, refractory macrocytic anemia with multilineage dysplasia" reportable?
For cases diagnosed prior to 1/1/2010:Yes, myelodysplasia, refractory macrocytic anemia with multilineage dysplasia is reportable. This is a type of refractory anemia. Refractory anemia is reportable.
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.
Primary Site: What site code best reflects the final diagnosis of a metastatic "pancreatobiliary" adenocarcinoma to the liver? See Discussion.
CT showed multiple masses in the liver and lymphadenopathy in areas of gastrohepatic ligament, celiac axis, superior mesenteric and left periaortic regions. No mention of a mass in pancreas or common duct. When the term "pancreatobiliary" primary is stated in the final diagnosis, what site code should be used?
Contact the physician for clarification of the term "pancreatobiliary." If no further information can be obtained for this case, assign code C249 [Biliary tract, NOS] based on the CT findings for the specific case in this question.
When the primary is described as "pancreatobiliary" with NO FURTHER INFORMATION, assign C269.
Surgery of Primary Site--Bladder: Should a TURB be coded to 27 [Excisional biopsy; SEER Note: Code TURB as 27] when there is obvious extravesicular extension demonstrated because the 2004 SEER Manual states "Do not code an excisional biopsy when there is macroscopic residual disease"?
Assign code 27 [excisional biopsy]. The site-specific instructions have priority over the general instructions. According to the instructions for coding surgery of the bladder, use code 27 for TURB.
Reportability--Brain and CNS: Is Langerhans cell histiocytosis [9751/1] of the meninges [C709] reportable?
For cases diagnosed prior to 1/1/2010:Yes. The criteria for reportable benign/borderline CNS tumors is based on location (site) and behavior (benign/borderline). There is no caveat for histologic type. Therefore, this would be reportable as these tumors have been reported arising from the meninges or choroid plexus.
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.
CS Site Specific Factor--Prostate: How are SSF 5 (Gleasons Primary and Secondary Pattern Value) and SSF 6 (Gleasons Score) coded when there is a higher Gleason's pattern in less than 5% of the tumor? See Discussion.
Radical prostatectomy pathology states prostate adenocarcinoma "combined Gleasons score 3+3=6, with a small portion of Gleasons pattern 4 component comprising less than 5% of tumor volume."
The WHO Classification of Tumors of the Urinary System and Male Genital Organs refers to "tertiary" Gleasons patterns in addition to the primary and secondary patterns. On prostatectomy, when this tertiary pattern is 4 or 5, WHO recommends that it should be reported in addition to the Gleasons score even when it is less than 5% of the tumor.
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.
Record Gleason's pattern and score from the largest specimen, even if this is a lower number. Ignore the tertiary pattern for now.
This may change when the AJCC 7th Edition is published, as there is much discussion regarding the tertiary patterns and when they should be utilized. If there is a change in AJCC, at that time there will be a change to CS.
First Course Treatment--Lymphoma: Should the use of proton pump inhibitors be coded as treatment for lymphoma primaries in patients with H Pylori?
No, do not code proton pump inhibitors as treatment. These are used for gastric acid suppression. Proton pump inhibitors are used to treat symptoms, not the lymphoma itself.
