20200076 | Reportability/Solid Tumor Rules (2018)--Kidney: Should clarification (Notes) be added to Table 1 of the 2018 Kidney Solid Tumor Rules regarding the use of clear cell papillary renal cell carcinoma (8323) and sarcomatoid renal cell carcinoma (8312) as these histologies conflict with the ICD-O-3.2? See Discussion. |
First, reportability of clear cell papillary renal cell carcinoma changed from 8323/3 to 8323/1. Although it does not appear the standard-setters implemented this change, note of the conflict between the ICD-O-3.2 and the Solid Tumor Rules (STR) is not included in the Implementation Guidelines or STR. The current Note for clear cell papillary renal cell carcinoma (8323) was left in Table 1, so this presumably is still reportable. It would be helpful if the conflict with ICD-O-3.2 was addressed, especially since the existing Note refers to changes made back in 2016 (not 2018 or 2021). Second, is the term sarcomatoid renal cell carcinoma still coded as a synonym for renal cell carcinoma (8312) because sarcomatoid is referring to a pattern of differentiation or 8318 (renal cell carcinoma, sarcomatoid)? The STR, Table 1, lists sarcomatoid renal cell carcinoma as 8312, but the ICD-O-3.2 lists this as 8318. The Note in Table 1 still indicates WHO/IARC and College of American Pathologists agree that sarcomatoid carcinoma is a pattern of differentiation, not a specific subtype, of renal cell carcinoma. This appears to conflict with WHO/IARC ICD-O-3.2 Coding Table as it provides a different, specific histology code for this malignancy. How can WHO/IARC classify this both a pattern of renal cell carcinoma and a separate, specific histology? This question was prompted from preparing SEER*Educate coding exercises. We will use the answer as a reference in the rationales. |
For cases diagnosed 2021 or later, use ICD-O-3.2 to determine reportability. Use the Solid Tumor Rules to determine the number of primaries to report and the histology to code for tumors that are reportable. Do not use the Solid Tumor Rules to determine reportability. ICD-O-3.2 was implemented by the North American standard setters as of 1/1/2021 and it is the basis for reportability for cases diagnosed as of 1/1/21. See 1.a on page 6 in the 2021 SEER manual, https://seer.cancer.gov/manuals/2021/SPCSM_2021_MainDoc.pdf WHO 4th edition Tumors of the Urinary System has proposed ICD-O code 8323/1 for clear cell papillary renal cell carcinoma. This has not been approved for implementation by the standard setters. Continue assigning 8323/3 for clear cell papillary renal cell carcinoma. Sarcomatoid RCC is listed as a synonym for RCC 8312/3. This is correct per WHO and our SME. Do NOT code sarcomatoid RCC to 8318/3. |

20110039 | Multiple primaries/Primary site--Heme & Lymphoid Neoplasms: What are the primary sites and how many primaries are abstracted, when 2004 diagnosis of grade 2 follicular lymphoma of the bilateral breasts is subsequently diagnosed with a 2010 diagnosis of diffuse large B-cell lymphoma (40%) and grade 3a follicular lymphoma (60%) of a left arm nodule? See Discussion. | Follicular lymphoma was diagnosed 7/2004, grade 2 per biopsy of the bilateral breasts. Bone marrow biopsy was positive for lymphoma involving 10% of bone marrow. Imaging showed extensive lymphadenopathy mainly in abdomen/pelvis with an 8 cm mass in the right pelvis. Smaller lymph nodes were noted in the left periaortic region and also some small precarinal lymph nodes. This was a stage IVA lymphoma. The patient had six cycles of CHOP/R with an excellent response. Per the clinician's notes on 12/2005, there was no evidence of recurrence or no sign of active disease. The plan was to follow up with the patient in 6 months.
08/22/06 imaging showed new disease in the bilateral chest wall. 8/2006 bilateral breast nodule biopsies, are positive for grade 1-2 follicular lymphoma. The patient was treated with Rituxan. Per clinician's 3/2007 note, no active disease is noted. Patient was regularly followed with no evidence of disease until 10/2010. At that time, the patient had a left arm nodule biopsy which was positive for diffuse large B cell lymphoma (40%) CD positive and grade 3a follicular lymphoma (60%). RICE was recommended due to "transformation" per oncologist. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Per Rule M10, this case should be accessioned as two primaries when a neoplasm is originally diagnosed as a chronic neoplasm (is follicular lymphoma (FL), grade 2) AND there is a second diagnosis of an acute neoplasm (diffuse large B-cell lymphoma) more than 21 days after the chronic diagnosis.
Code the histology for the first primary to 9691/3 [follicular lymphoma (FL), grade 2] and the primary site to bilateral C509 [breast, NOS]. FL can start as an extranodal disease; breast is one of the sites in which it originates. It is unlikely that the lymphoma extended from the nodes to the breast, but highly likely that it extended from the breast to the nodes.
Per Rule M4, abstract the 2010 disease process as a single primary when two or more types of non-Hodgkin lymphoma are simultaneously present in the same anatomic location(s), such as the same lymph node or lymph node region(s), the same organ(s), and/or the same tissue(s). Per Rule PH11 the primary site is coded to C779 [lymph nodes, NOS] and the histology is coded to 9680/3 [diffuse large B-cell lymphoma (DLBCL)]. Rule PH11 states one is to code the primary site to the site of origin, lymph node(s), lymph node region(s), tissue(s) or organ(s) and histology to diffuse large B-cell lymphoma (DLBCL) (9680/3) when DLBCL and any other non-Hodgkin lymphoma are present in the same lymph node(s), lymph node region(s), organ(s), tissue(s) or bone marrow.

20200052 | Solid Tumor Rules (2018)/Histology--Prostate: How is the histology coded for a diagnosis of mixed prostatic adenocarcinoma (5%) and small cell neuroendocrine carcinoma (95%) from a transurethral resection of the prostate? See Discussion. |
Following the existing Solid Tumor Rules Histology Rules, it would seem this is a single primary with histology 8045 (Combined small cell carcinoma) because there is no indication there are multiple prostate tumors and Table 2 states combined adenocarcinoma and small cell carcinoma is Combined small cell carcinoma (8045). Conversely, while not an exact match to this case, SINQ 20190083 implies small cell carcinoma and adenocarcinoma of the prostate are separate primaries. In that SINQ case, the patient was simultaneously diagnosed with metastatic small cell carcinoma of the prostate on a liver biopsy and prostate adenocarcinoma on a prostate biopsy. There is no indication that patient had separate tumors in the prostate, however the SINQ instructs to code as separate primaries. Would the previous SINQ logic apply to synchronous diagnoses in the prostate as well? Or does code 8045 apply to this situation? |
Assign histology code 8045 for combined small cell carcinoma as this represents one tumor with mixed histologies using the 2018 Other Sites Solid Tumor Rules, Rule H16. |

20230073 | First Course Treatment/Surgery of Primary Site--Liver/Intrahepatic Bile Ducts: For a liver/intrahepatic bile duct primary, is an alcohol embolization the same thing as a percutaneous ethanol injection (PEI)? See Discussion. |
For C220-C221 primaries, Surgery of Primary Site includes code A150 for Alcohol tumor destruction (percutaneous ethanol injection/intratumoral injection of alcohol/alcohol ablation). The SEER and STORE manuals also indicate that alcohol embolization should be coded as Other Therapy, code 1. We are trying to determine whether alcohol embolization should be coded under Surgery of Primary Site or Other Therapy. |
Code alcohol ablation under Surgery of Primary Site 2023. Code alcohol embolization as Other Therapy when tumor embolization is performed using alcohol as the embolizing agent. Alcohol ablation, also known as an ultrasound-guided percutaneous ethanol injection (PEI); is treatment that involves injecting concentrated alcohol directly into the tumor. Embolization uses special techniques to close off blood flow by introducing special medications or using other techniques designed to block blood vessels. Types of embolization are arterial embolization as with alcohol (ethanol), chemoembolization, and radioembolization. Refer to the current SEER Program Coding and Staging Manual when assigning surgery and embolization procedures. |

20031115 | EOD-Lymph Nodes/EOD-Extension: Does extracapsular lymph node extension into adjacent tissue or organs affect EOD coding? See Description. | For a lung primary a PET scan showed marked uptake in the right hilum consistent with metastatic disease. A radical pneumonectomy was performed and the operative findings showed that the pulmonary artery was involved with a mass. Pathology: Small cell carcinoma in the lung parenchyma. The distal bronchi showed obstructive pneumonitis. There were mets found on 02/05 on the hilar lymph nodes and 00/02 peribronchial nodes. The mets in the hilar nodes extended beyond the lymph node capsule into the pulmonary artery. |
For cases diagnosed 1998-2003: Extracapsular lymph node extension does not affect the extent of disease. Code the extent of regional lymph node involvement in EOD lymph nodes. | 2003 |

20091018 | MP/H Rules/Multiple Primaries/CS Extension: How many primaries are to be accessioned when tumors are present bilaterally in the pleura and fallopian tubes? See Discussion. | For both pleura and fallopian tube, the MP/H rules indicate that bilateral involvement of these sites should be coded as multiple primaries. However, both of these sites have CS extension codes that classify the contralateral disease as regional extension. Is a case described as a left sided pleural mesothelioma that has right sided pleural disease coded as one or two primaries? How is CS coded? |
For cases diagnosed 2007 or later: For a pleural or fallopian tube primary, if there is tumor(s) on the left and separate tumor(s) on the right and neither is stated to be metastatic from the other, abstract as multiple primaries according to rule M8 for other sites. If both sides are involved, but there is only one tumor, rule M2 for other sites applies and this is a single primary. Code each primary separately in CS. |

20100042 | Reportability--Heme & Lymphoid Neoplasms: Given that there appears to be many differences in the reportability of these case types pre- and post-2010 (e.g., [refractory] thrombocytopenia), is there a list available that gives the reportability dates for these diseases? See Discussion. |
For cases diagnosed prior to 2010 "thrombocytopenia" was not reportable. According to the Heme Database, the term "refractory thrombocytopenia" is now reportable for cases diagnosed 1/1/10 and later. It would be helpful to have a list of diagnosis date requirements for the different hematopoietic diseases. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Thrombocytopenia (NOS) is not reportable per Appendix F. However, the term "refractory thrombocytopenia" [9992/3] is reportable for cases diagnosed 2010 or later.
There has been no change in the reportability for thrombocytopenia. The hematopoietic "help" system lists all of the synonyms, variants, and abbreviations for diseases.
See the Hematopoietic & Lymphoid Neoplasm Coding Manual for changes in reportability associated with these cases.
Terms and codes in Appendix D are effective 01/01/10 and later. Refractory thrombocytopenia is included in D1a and D1b. The notes for D1a and D1b provide explanation and reiterate the dates these terms are effective.

20180045 | Solid Tumor Rules (2018)/Histology--Breast: The Histology Coding Instructions for breast cancer indicate the term type is not used to code histology unless documented to be greater than or equal to 90% of the tumor. Does this also apply if the format of pathology reports submitted in the College of American Pathologists (CAP) protocol from a specific facility always describes the histology under the heading, Histologic type: ___? See Discussion. |
For certain facilities in our area, the breast pathology reports using a CAP protocol format are formatted as follows; the Final Diagnosis will state Infiltrating carcinoma with the following features. The features list the specific tumor characteristics required in the CAP protocol formatting. The histology is always displayed in the list form and specified as Histologic type: (for example, Histologic type: Ductal carcinoma). Is this specific histology really to be ignored because it is preceded by the word type even if this is just a consequence of the pathology report formatting? |
In the CAP protocol, the term Histologic Type is a label where the histology that corresponds to the largest carcinoma is collected. According to the CAP protocol for invasive breast cancer, the histologic type corresponds to the largest carcinoma. If there are smaller carcinomas of a different type, this information should be included under "Additional Pathologic Findings." The findings noted in the Final Diagnosis, Histologic Type, and Additional Path Findings of the protocol should be used to determine the histology. When there are multiple histologies and 1) the subtype or variant is listed as 90% when there is a Not Otherwise Specified/No Specific Type (NOS/NST) and a subtype, or 2) the subtype/variant histology reflects the majority of the tumor when there are two or more different histologies (two or more distinct subtypes) Code the subtype/variant; otherwise, use the Specific and Not Otherwise Specified/No Specific Type (NOS/NST) Terms and Code listed in Table 2 (columns 1 and 2) of the 2018 Solid Tumor Rules for Breast Cancer. |

20190072 | Solid Tumor Rules (2018)/Histology--Lung: What is the correct histology code for minimally invasive adenocarcinoma in the lung, 8140/3 or 8256/3? See Discussion. |
For example, 9/12/18 left lung upper lobe lobectomy: 1.5 cm, 0.8 cm invasive component, lepidic predominant adenocarcinoma with acinar and lepidic patterns, G2, no visceral pleural invasion, no LVI, 0/14 LNS positive. An additional minimally invasive adenocarcinoma, 1 mm, was seen away from the main tumor. The correct coding of the minimally invasive adenocarcinoma will ultimately determine if we have one tumor (using rule M7) versus two primaries (using rule M6). |
Updated answer: Code minimally invasive adenocarcinoma, NOS as 8140/3. This is a new term and code in the 2018 ICD-O-3 New Codes, Behaviors, and Terms-Updated 8/22/18 list. See Solid Tumor Lung Table 3, and Solid Tumor Lung rules H1 and H10. |

20240078 | Reportability/Histology--Lung: Are adenocarcinoma spectrum lesions on lung imaging reportable when no further information is available? See Discussion. |
For example, a chest computed tomography showed multiple subsolid and ground glass pulmonary nodules measuring up to 6 mm; findings favored to reflect adenocarcinoma spectrum lesions. A literature search seems to indicate that adenocarcinoma spectrum lesions include atypical adenomatous hyperplasia through invasive adenocarcinomas. |
Do not report this case of "adenocarcinoma spectrum lesions" based on the information provided in the absence of a more specific diagnosis. Do not report until/unless a definitive diagnosis of malignancy is made. "Adenocarcinoma spectrum lesion" covers a continuum of lung neoplasms from preinvasive lesions (atypical adenomatous hyperplasia and adenocarcinoma in situ) to invasive lesions (minimally invasive adenocarcinoma and invasive adenocarcinoma). Should additional information become available, report the case and assign the histology code if a more specific histology is confirmed later. Use text fields to record the details.
