Multiple Primaries (Pre-2007)/Recurrence--Cervix: How many primaries should be abstracted if a patient had a diagnosis in 1998 of adenocarcinoma in situ of the cervix treated with a total hysterectomy and a July 2004 vaginal mass biopsy with a diagnosis of invasive adenocarcinoma that is consistent with an endocervical primary?
For tumors diagnosed prior to 2007:
Abstract the July 2004 diagnosis as a new endocervical primary. Abstract an invasive cancer in the same site more than two months after an in situ cancer as a new primary. Residual cervical tissue is present following a hysterectomy.
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/Diagnostic Confirmation--Leukemia: What is the diagnostic confirmation if a positive BCR/ABL result is diagnostic of a malignancy in a patient suspected to have chronic myelogenous leukemia? See Discussion.
Example 1: Peripheral smear states: "No morphologic evidence of chronic myelogenous leukemia."
Addendum: Molecular diagnostic studies showed a positive rearrangement for the BCR gene with the M-bcr (CML type) and of bcr-abl transcript expression".
Example 2: Hematopathology is negative.
Molecular diagnostic study: "fluorescent in situ hybridization (FISH) studies exceeded the limits established by the XXX Cytogenetics Laboratory for this probe set, and thus, demonstrated statistical evidence of BCR/ABL fusion."
For cases diagnosed prior to 1/1/2010:
Do not determine reportablility using cytogenetics or molecular studies alone.
Since these are not routine screening tests, we suggest that you query the physician and review the medical record to see what prompted the study and what is being done with the result, but the test alone is not in and of itself sufficient to report the case.
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 Lymph Nodes--Breast: Are small isolated tumor emboli occasionally found in lymph node capsular or pericapsular lymphatics sufficient to code as a lymph node metastasis?
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.
Code "small isolated tumor emboli" in the pericapsular lymphatics detected by H&E that are less than 0.2 mm as 05 [Regional lymph node(s) with ITC's detected on routine H & E stains].
CS Reg LN Pos/Exam--Colon: For a patient with both a prostate and colon primary, if the pathology report indicates that 2 of the 3 regional lymph nodes to the colon are positive for a prostate malignancy, how should these fields be coded for the colon primary?
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 the colon primary, code Reg LN Pos 00 [all nodes negative]. Code Reg LN Exam 03 [three nodes examined].
Three lymph nodes were examined and found to be negative for metastatic colon cancer.
First Course Treatment/Surgery of Primary Site--Lung: How is radiofrequency ablation for lung primaries coded?
Assign code 15 [Local tumor destruction, NOS] in the Surgery of Primary Site field. RFA is a technique where a probe placed in or near a tumor sends radio waves into the tumor, causing it to heat up and kill the cancer cells. RFA doesn't fit neatly into code 12 or 13, so we are left with the NOS code.
Histology (Pre-2007)/Diagnostic Confirmation: Which histology code is preferred if the CBD brushing is positive for malignant cells, cytologically most consistent with ductal adenocarcinoma [8500/3], and the common hepatic artery lymph node biopsy has metastatic adenocarcinoma, consistent with cholangiocarcinoma [8160/3]?
For tumors diagnosed prior to 2007:
Assign histology code 8160 [Cholangiocarcinoma]. Code from the pathology specimen when available. In this case, the only pathology is from the lymph node specimen.
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.
Histology (Pre-2007)--Melanoma: How is histology coded if the final diagnosis is "melanoma" and only in the comment section of the pathology report is there an indication of "Type: Lentigo Maligna. Cell Type: Small Cell"?
For tumors diagnosed prior to 2007:
Code the histology as 8742 [lentigo maligna melanoma]. Code the specific histologic type, even if stated only in the comment section.
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.
Primary Site--Sarcoma: What is the correct topography code for a partial lung lobectomy with pathology diagnosis of "pulmonary sarcoma with smooth muscle differentiation"? See Discussion.
Operative report: palpable 2x2cm mass in the mediastinal surface of the rt middle lobe and the contiguous upper lobe together.
Path comment after partial lung lobectomy: In all likelihood this is a malignant process occurring in smooth muscle changes surrounding vessels within the lung versus an undifferentiated epithelial tumor.
ADDENDUM DX: low grade pulmonary sarcoma with smooth muscle differentiation.
Consultant's report concurs with that of the original pathologist's report of malignant neoplasm compatible with smooth muscle origin.
This case is unique. Assign topography code C493 [Connective, subcutaneous and other soft tissue of thorax]. Based on the information provided, this sarcoma has smooth muscle differentiation and originated in the muscle. Code the primary site to muscle.
