20190086 | EOD 2018/Primary tumor--Melanoma: The code and level translations in the Note 4 of Extent of Disease (EOD) Primary Tumor for Melanoma Skin seem incorrect. Please advise. * Code 000: In situ * Code 100: Level I (should be level II) (< 0.75 mm Breslow's Depth) * Code 200: Level II (should be level III) (0.76 mm to 1.50 mm Breslow's Depth) * Code 300: Level III (should be level IV) (> 1.50 mm Breslow's Depth) |
Please see the corrected levels below for the note. Note 4: If a Breslow's depth is given in the pathology report and there is no other indication of involvement, the following guidelines may be used (Note: If a physician documents a different Clark's Level than provided by these guidelines, go with the physician's Clark Level) Code 000: Level I (In situ) Code 100: Level II (< 0.75 mm Breslow's Depth) Code 200: Level III (0.76 mm to 1.50 mm Breslow's Depth) Code 300: Level IV (> 1.50 mm Breslow's Depth) Thank you for bringing this to our attention. |

20240046 | Reportability/Histology--Stomach: According to the AJCC manual, histology codes 8240 and 8249 are excluded from site code C160. Does that mean that I cannot use either of these histology codes with C160 even if the pathologist's diagnosis is neuroendocrine carcinoma? |
Please understand that AJCC sets the standards for TNM Staging and the Cancer PathCHART (CPC) initiative sets standards for the validity of site and morphology combinations. The statement in the AJCC manual “8240 and 8249 are excluded for topography code C160” means that these two histologies are not staged using the AJCC Staging System. As with numerous other reportable entities that are not staged by AJCC, the case is reportable and a Summary Stage should be assigned. Combinations of C160 with 8240 or 8249 are valid site/histology combinations for registry reporting and should not be discouraged from use if they correspond to the pathologist’s diagnosis. This goes for any other similar note in the AJCC manual. All CPC standards are enforced via the Primary Site, Morphology-Type, Beh ICDO3, 2024 (SEER) N7040 and Histologic Type ICDO3, Primary Site, Date of Diagnosis (NAACCR) N4911 data quality edits. Registrars can also look up the validity of site and morphology combinations using the CPC*Search tool: https://seer.cancer.gov/cancerpathchart/search/tool/. It is important to remember the following.

20061062 | Reportability: Is a "pleomorphic hyalinizing angiectatic tumor of soft parts (PHAT)" reportable if the case has a TNM stage assigned and is stated by the pathologist to be a rare intermediate grade sarcoma? | Pleomorphic hyalinizing angiectatic tumors of the soft parts are not reportable. According to our pathologist consultant, PHAT is a borderline malignancy (/1). While the true nature of these tumors is under debate (reactive vs. neoplastic), so far none have metastasized. |

20140081 | Reportability/Histology--Heme & Lymphoid Neoplasms: Is primary erythrocytosis equivalent to primary polycythemia and thus reportable? See discussion. |
Per the Heme Manual, Appendix F - Non-Reportable list for Heme Diseases, under Polycythemia, the Comment states that polycythemia is also known as erythrocytosis. Because polycythemia is equivalent to erythrocytosis, can we assume that "primary erythrocytosis" is equivalent to "primary polycythemia" and thus reportable as 9950/3 per the Heme DB? Or is the case nonreportable because the exact term of "primary erythrocytosis" is not listed as an alternate name for polycythemia vera, only "primary polycythemia" is listed? |
Primary erythrocytosis is not equivalent to primary polycythemia and is not reportable. This will be clarified in a future revision. Thank you for point it out to us. |

20180097 | Reportability/Histology--Liver: Are primary hepatic neuroendocrine neoplasm and primary hepatic neuroendocrine tumor (PHNET) reportable? What are the specific histology codes? |
Primary hepatic neuroendocrine tumor (PHNET) is reportable as are other digestive system NETs. There is no specific histology code for PHNET. We suggest you assign 8240/3. Use text fields to document the details. Unless you can obtain clarification, do not report primary hepatic neuroendocrine neoplasm with no further information. If this term is being used as a synonym for PHNET, document this in the registry's policies and procedures, and report these cases. |

20230077 | EOD 2018/ Primary Site/Heme & Lymphoid Neoplasms--CLL/SLL: How are Primary Site and Extent of Disease (EOD) Primary Tumor coded when a lymph node biopsy proved chronic lymphocytic leukemia (CLL), and the peripheral blood is involved with an “abnormal CD5-positive B-cell population”? See Discussion. |
The patient has adenopathy in multiple lymph node regions above and below the diaphragm and a lymph node biopsy pathology proved CLL/small lymphocytic lymphoma (SLL). Further work-up with peripheral blood proved an abnormal CD5-positive B-cell population comprising only a small percentage of the white blood cells (WBCs). The pathologist noted this neoplastic B-cell population comprises “3.5% of white blood cells and has an immunophenotype characteristic of CLL/SLL and is similar to the recent lymph node biopsy in this patient.” The managing physician indicated this was a Lugano Stage III SLL. The registrar coded the peripheral blood involvement in EOD Primary Tumor. If this small percentage of WBCs with an abnormal B-cell population is included in EOD Primary Tumor as peripheral blood involvement, then this would indicate peripheral blood/bone marrow involvement and primary site would need to be coded to C421 per Rule PH5. Rules PH5 and PH6 confirm primary site must be coded C421 if peripheral blood or bone marrow are involved. Is there a cutoff value for these abnormal B-cell populations in the peripheral blood? Or should these abnormal B-cell populations be ignored unless the pathologist states the abnormal B-cell population is consistent with CLL/SLL (not just immunophenotypically characteristic of CLL/SLL)? |
Primary site would be C421 based on Hematopoietic and Lymphoid Neoplasm Manual, Module 3, Rule PH 5. Assign EOD Primary Tumor to code 800 (peripheral blood involvement WITH other involvement). Per consultation with an expert hematologist oncologist, this is a Stage IV CLL/SLL since the peripheral blood is involved. There is no cutoff value for the abnormal B-cell populations in the peripheral blood when the cells are consistent with CLL/SLL. If the peripheral blood is involved, even only slightly, it is a Stage IV CLL/SLL. Our expert stated that the physician's staging was wrong (this is not a Lugano, Stage III). |

20220008 | Reportability/Histology--Soft Tissue: Is atypical spindle cell neoplasm, primitive myxoid mesenchymal tumor of infancy (PMMTI) from the soft tissue of the leg in August of 2019, reportable? |
Primitive myxoid mesenchymal tumor of infancy (PMMTI) is reportable. PMMTI is listed in the new WHO 5th edition Classification of Soft Tissue and Bone Tumors under round cell sarcomas. This is a variant of BCOR sarcomas. There is a new ICD-O histology code assigned for cases diagnosed in 2022 or later (9368/3). Code this 2019 case to round cell sarcoma, undifferentiated 8803/3. Use text fields to explain the details. |

20150049 | Reportability--Brain and CNS: Is pseudotumor cerebri reportable? |
Pseudotumor cerebri is not reportable. It is not a neoplasm. The pressure inside the skull is increased and the brain is affected in a way that appears to be a tumor, but it is not a tumor. |

20160035 | Reportability/Histology--Pituitary Gland: How are Rathke cleft cyst and Rathke pouch tumor distinguished and are they both reportable? |
Rathke cleft cyst is not reportable. Cysts are not neoplastic. However, Rathke pouch tumor (C751, 9350/1) is a reportable neoplasm for cases diagnosed 2004 and later. The Rathke pouch is coded to the pituitary gland. Benign and borderline pituitary tumors have been reportable since 2004. |

20150040 | Surgery of Primary Site--Pleura: How is this field coded if the patient underwent an exploratory thoracotomy with partial decortication that excised some, but not all, of the pleural mesothelioma tumors? See Discussion. |
This patient underwent a "partial decortication" per the operative report. While the operative report does not specifically note that this was performed with a partial pleurectomy, it appears the patient had a partial pleurectomy because the largest specimen removed was a "pleural peel" specimen, which included the parietal and visceral pleural surfaces with a small amount of underlying lung tissue. The operative report notes the patient had involvement of both the lung and chest wall. A total resection was not possible due to the extent of the tumor. However, this patient does appear to have undergone at least a partial resection of the pleura/tumor burden. The patient did not simply undergo a pleurodesis to free adhesions. Per the NCI's PDQ, pleurectomy and decortication are performed together. Because the operative report and pathology report only called this procedure a "partial decortication" without specifically mentioning a pleurectomy, would this be coded as a tumor excision (surgery code 20)? Or should we assume the procedure is best coded as a partial pleurectomy and decortication and use code 30 (simple/partial resection)? |
Read the operative report and the pathology report and assign the surgery code that best represents the extent of the surgery. In this case, code 30 seems most appropriate. Do not assign the surgery code based only on the name of the procedure; use all information available to chose the most representative code. |
