20071125 | Radiation Therapy--Prostate: Is the regional treatment modality XRT best coded to 50 (brachytherapy, NOS), 53 (LDR) or 54 (HDR) when the documentation indicates only "I-125 seeds" to the prostate? | Assign code 53 [Brachytherapy, interstitial, LDR] for seeds to the prostate. Seeds are always low dose because they are left in place and the radioactivity decays over time. | 2007 | |

20071119 | CS Eval/Surgery of Primary Site--Colon: When the only procedure performed is a polypectomy, if there is NO tumor at the margins, should CS TS/EXT-Eval be coded as 3 and the surgery coded as a polypectomy? | 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 eval code 3. A polypectomy with no tumor at the margin meets the criteria for pathologic staging. Code polypectomy in Surgery of Primary site in this case. |

20071068 | MP/H Rules/Multiple Primaries/Histology--Prostate: How many primaries should be abstracted and how should the histology field(s) be coded for a case in which the pathology specimen showed adenocarcinoma in 20% of the tissue and sarcoma in 50% of the tissue? See Discussion. | Patient has TURP. The final path diagnosis is adenocarcinoma in 20% of tissue and sarcoma in 50% of tissue. Because it is unknown whether there is a single or multiple tumors, rule M1 (Other Sites) is used which states the case is to be abstracted as a single primary. Single invasive histology rules are followed to rule H16, but table 2 does not contain a mixed code for this situation, even though ICD-O-3 has a code 8933/3 for "adenosarcoma". Therefore, rule H17 is applied that states to use the highest code, which in this case would be 8800/3 [Sarcoma, NOS]. Is this correct? |
For cases diagnosed 2007-2014, code as two primaries, one adenocarcinoma and the other sarcoma. This is two tumors (adenocarcinoma and separate sarcoma) until proven otherwise. Do not code as adenosarcoma, as this is a gyn-specific diagnosis. Adenosarcoma of the prostate is not a recognized entity in the WHO classification of prostate tumors. |

20071035 | CS Extension--Prostate: Should CS Clinical Extension always be coded to 99 [Extension unknown] for prostatic adenocarcinoma found incidentally during surgery for another primary or at autopsy? See Discussion. | Patient had a cystoprostatectomy for bladder cancer. Pathology report states only 2 microscopic foci of prostate adenocarcinoma found on LEFT side of gland. Physician notes state patient has been followed for 4 years with a nodule in the RIGHT prostate and has refused biopsy despite rising PSA. There was no definite statement of suspected cancer.
Should CS Clinical Extension be coded 99 because prostate cancer wasn't clearly stated to have been suspected until cystoprostatectomy? Or could we code the right-sided "nodule" as clinically apparent (CS Extension 20), even though path found tumor only on the left (which is how we would code a standard prostate case)? |
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 CS extension 99 [Extension unknown]. This prostate cancer was not clinically evident; it cannot be clinically assessed based on the information provided. Note: This is an unusual case. A DRE was performed and a nodule was palpated on the right that was not cancer. The other lobe is presumed to have been negative because it was not mentioned. |

20071130 | Reportability--Brain and CNS: Are schwannomas of the spinal cord reportable when they are intradural? See Discussion. | The CNS guidelines basically indicate that schwannomas must all come from peripheral nerves and thus are not reportable when they are on the spinal cord. However, the COC Inquiry 18174 & 18068 states that schwannomas occasionally will develop inside the dura (intradural) on the spinal cord and would be reportable. | According to an expert consultant, schwannomas must be derived from Schwann cells which are not a part of the CNS. All schwannomas come from peripheral nerves. Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable. Please see http://www.cdc.gov/cancer/npcr/training/index.htm for more information. |

20071063 | Reportability/Diagnostic Confirmation: If a diagnosis based solely on positive flow cytometry is reportable even if a bone marrow biopsy is negative, how is diagnostic confirmation coded? |
For cases diagnosed prior to 2010 The case is reportable if a recognized medical practitioner says the patient has cancer. A flow cytometry alone is not diagnostic but it may be supported by either a positive bone marrow or a clinician's statement. If the clinicians statement is based only on flow cytometry, code diagnostic confirmation to 8 [Clinical diagnosis only]. |

20071131 | Cell indicator--Lymphoma: If the primary site for a lymphoma is stated to be the lymph nodes but there is no biopsy of a lymph node, can the immunophenotype designation for a lymphoma be coded based on a bone marrow or liver biopsy indicating "diffuse large B-cell lymphoma"? | For cases diagnosed prior to 1/1/2010: The cell indicator or immunophenotype designation for lymphomas may be coded from pathology reports on tissue from bone marrow or liver when there is no tissue from the primary site. Code information on cell type from any available source. See the Appendix C of the 2007 SEER manual, Coding Guidelines for Lymphomas, pages C-1055 to C-1056 for more information about coding this field for lymphomas. 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. |

20071022 | Reportability--Hematopoietic, NOS: If the bone marrow biopsy diagnosis is not reportable and cytogenetics studies indicate no clonal abnormality, is a case reportable if only the flow cytometry results show a "small monoclonal B-lymphocyte population consistent with a lymphoid component of a lymphoplasmacytic lymphoma or Waldenstrom macroglobulinemia"? See Discussion. | Bone marrow bx final diagnosis: Markedly hypercellular marrow consisting primarily of erythroid hyperplasia and, also, diffusely distributed small lymphocytes. Addendum comment: Flow cytometry demonstrated a small monoclonal B-lymphocyte population consistent with a lymphoid component of a lymphoplasmacytic lymphoma or Waldenstrom's Macroglobulinemia. Addendum comment: Cytogenetic analysis states no clonal abnormality was apparent. Normal female karyotype. Question 1: Is this case reportable, and if so, what histology? Question 2: Is there a hierarchy when flow cytometry and cytogenetics are done, but do not agree? |
For cases diagnosed prior to 1/1/2010:This case is not reportable at this point. A lymphoid component is not equivalent to a diagnosis of a reportable disease. In order to be a malignant, reportable disease, the condition must be monoclonal and irreversible. Cytogenetics were negative for malignancy (i.e. no monoclonal abnormality identified which is the criteria used to establish this diagnosis). Use all information available when determining reportability. 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. |

20071085 | CS Tumor Size/CS Extension--Prostate: Because prostatectomy results are excluded from the CS Extension field for prostate, is code 95 [No evidence of primary tumor] accurate to reflect bilateral lobe involvement of prostate cancer when it is incidentally found following a radical cystectomy for a bladder primary? Why must tumor size be 000 when the CS Extension code is 95? | 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 prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery. CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used. |

20071122 | MP/H Rules/Histology--Colon: How is histology coded when the final pathology diagnosis is "adenocarcinoma with extensive mucinous features" and the percent of mucinous features is not stated? |
Code 8140 using rule H6. Rule H6 applies because the percent of mucinous is not specified. |
