Reportability/In Situ--Prostate: Was there a time period when PIN III was reportable to SEER?
Per the 2004 SEER Manual, page 2, Reportable Diagnoses, Exceptions, 1.b.iii "Prostatic intraepithelial neoplasia (PIN III) of the prostate (C619). (Collection stopped effective with cases diagnosed 1/1/2001 and later.)"
Grade--Breast: How is this field coded for an "invasive ductal carcinoma, well differentiated, low nuclear grade"?
Assign code 1 [Grade 1, well differentiated]. Use the table in the 2007 SEER Manual on page C-607. Both "low grade" and "well differentiated" are coded 1 in the grade field.
Idiopathic thrombocytic purpura (ITP) is not a synonym for refractory thrombocytopenia (RT). ITP is not a reportable disease. See Appendix F.
Under the Alternate Names section in the Heme DB, the only synonym for refractory thrombocytopenia is "RT." ITP is not listed as a synonym for refractory thrombocytopenia.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
Histology/Date of Diagnosis--Hematopoietic, NOS: What code is used to represent histology for a June 2001 diagnosis of "myelodysplastic syndrome" followed by a September 2001 bone marrow biopsy diagnosis of "myelodysplasia evolving into an acute leukemic state"?
For cases diagnosed prior to 1/1/2010:
Code the Histology field to 9989/3 [myelodysplastic syndrome] and the Date of Diagnosis field to June 2001.
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--Heme & Lymphoid Neoplasms: Should the primary site be coded to C421 [bone marrow] or C770-C779 [lymph nodes] for an adult T-cell leukemia/lymphoma [9827/3] that presented with a positive bone marrow biopsy and involvement of lymph nodes and the lung?
Code the primary site to the involved lymph nodes [C770-C779]. Per Rule PH 8, it indicates you are to code the primary site to the site of origin when lymph node(s) or lymph node region(s), tissue(s) or organs are involved. Note 2 further states that the bone marrow may or may not be involved. If the bone marrow is involved, code this information in the CS Extension field.
Per the Abstractor Notes section in the Heme DB, this is a systemic disease with widespread lymph node involvement as well as involvement of the peripheral blood. In addition, systemic involvement of extranodal sites (including lung) are often involved.

Reportability--Heme & Lymphoid Neoplasms: Is the term "thrombocytopenia" equivalent to the term "refractory thrombocytopenia" and should be a subsequent primary if it follows a treated diagnosis of pancreatic cancer?
Thrombocytopenia NOS is not a reportable diagnosis per Appendix F. Thrombocytopenia and Refractory Thrombocytopenia are not the same disease.
Thrombocytopenia is caused by a decreased number of platelets in the blood. Non-malignant causes include disseminated intravascular coagulation (DIC), drug-induced non-immune thrombocytopenia, drug-induced immune thrombocytopenia, hypersplenism, immune thrombocytopenic purpura (ITP), thrombotic thrombocytopenic purpura, and infections of the bone marrow.

Primary Site (Pre-2007)--Prostate/Prostatic Urethra: What code is used to represent primary site for an "adenocarcinoma with spindle cell differentiation" of the prostatic urethra?
For tumors diagnosed prior to 2007:
Code the Primary Site field to C61.9 [prostate] because the histology is adenocarcinoma.
When a malignancy is identified in the prostatic urethra, look at the histology to determine the primary site. If it is a transitional cell carcinoma, code the Primary Site field to C68.0 [urethra] and if it is an adenocarcinoma, code to C61.9 [prostate].
The EOD scheme is ultimately collapsed into the TNM scheme. The TNM system differentiates between adenocarcinoma of the prostate and transitional cell carcinoma of the urethra. Only adenocarcinoma of the prostate is staged by the prostate scheme. Transitional cell carcinoma of the prostatic urethra is coded to C68.0 [urethra] and staged with that scheme.
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/CS Mets at Dx--Lung: How are these fields coded for bilateral pleural effusion for a right lung primary? A code of 72 in the CS Extension field leads to a T4, but bilateral pleural effusion is M1. Should CS Mets at Dx be coded 39?
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 bilateral malignant pleural effusion, code the ipsilateral malignant effusion in CS Extension and the contralateral malignant effusion in CS Mets at Dx. Assuming the bilateral pleural effusion is the furthest extension in this case, code CS Extension to 72 [Malignant pleural effusion]. Code CS Mets at Dx to 40 [Distant mets, NOS].
