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. |

20160055 | Reportability--Bone: Is an "atypical cartilaginous tumor" reportable? See Discussion. |
Patient had a core needle biopsy of the right acetabulum. Final diagnosis on the path report is: Atypical cartilaginous tumor (formerly chondrosarcoma, grade 1).
Is this cell type reportable? If so, is it reportable only because the pathologist recorded clarifying text in parentheses? If the text in the parentheses was not available, is the histology "atypical cartilaginous tumor" reportable? |
Atypical cartilaginous tumor of bone is not reportable. The WHO terminology is "atypical cartilagenous tumor/chondrosarcoma grade I." WHO classifies this entity as low malignant potential (behavior code /1).
Chondrosarcoma grade II or grade III is reportable based on the WHO classification of malignant (behavior code /3). |

20180078 | Solid Tumor Rules (2018)/Histology--Breast: How is histology coded and which rule applies for a single in situ tumor that is described as an encapsulated papillary carcinoma (EPC) with conventional ductal carcinoma in situ (DCIS)? See Discussion. |
Patient had a breast excision that proved a single tumor with no evidence of invasive carcinoma. The final diagnosis stated: Size (extent) of EPC DCIS: Spanning approximately 1.3 cm. The pathologist did not describe separate foci of DCIS; only one tumor comprised of both encapsulated papillary carcinoma and DCIS. The encapsulated papillary carcinoma was not described as invasive. The pathology noted: This case is best classified as EPC conventional DCIS. No conventional stromal invasion is identified. Solid Tumor Rule M2 confirms a single tumor is a single primary. However, there does not appear to be an H Rule that instructs how to code histology. The Single Tumor: In Situ Only module, has only three H Rules and none of them apply to this case. The patient does not have Paget disease (H1), does not have a single histology (H2, there are multiple histologies present as DCIS and EPC are listed on different rows in Table 3) and does not have DCIS and LCIS (H3). How does one arrive at the correct histology for this case? |
Code histology to 8500/2. Per April 2019 update: Rule H5 applies: Code DCIS 8500/2 when there is a combination of DCIS and any other carcinoma in situ. The 4th Ed WHO Tumors of the Breast states that tumors with encapsulated papillary carcinoma in situ in the absence of DCIS in the surrounding tissue have a very favorable prognosis. Only tumors without DCIS should be coded to 8504/2. The component of DCIS will determine treatment. |

20170058 | MP/H Rules/Histology--Lung: What is the correct histology code for an initial biopsy of non-small cell carcinoma with neuroendocrine phenotype, possible large cell neuroendocrine carcinoma with a subsequent re-biopsy showing poorly differentiated small cell carcinoma after chemotherapy with no response? See discussion. |
Patient had a biopsy in April 2014; pathology was reported as non-small cell carcinoma with neuroendocrine phenotype, possible large cell neuroendocrine carcinoma. The patient had five cycles of cisplatin/etoposide with no response. In May 2015, a re-biopsy at a referral institution reports poorly differentiated small cell carcinoma and states "feels that this could have been the histology all along and why patient has failed multi lines of chemo." |
Code to 8041, small cell carcinoma, because the medical opinon confirms that this was the correct histology from the begining. "Possible" is not an ambiguous term used to code histology. The MP/H rules do not include coding phenotype. That leaves non-small cell (8046/3) at time of diagnosis. Chemotherapy does not alter cell type so its likely the tumor was small cell all along only now proven with additional testing. Page 14 of the SEER Coding Manual gives examples of when to change the abstract's original codes and here is one example: When better information is available later. Example 1: Consults from specialty labs, pathology report addendums or comments or other information have been added to the chart. Reports done during the diagnostic workup and placed on the chart after the registrar abstracted the information may contain valuable information. Whenever these later reports give better information about the histology, grade of tumor, primary site, etc., change the codes to reflect the better information. |

20071017 | CS Extension--Prostate: Can the phrase "hard, fixed prostate" be interpreted as clinical extracapsular extension and coded to 50 [extension or fixation to other structures]? See Discussion. | Patient had a "hard, fixed prostate" with needle core bx positive for Gleason grade 4+5=9 adenocarcinoma extensively involving gland. PSA was 87.5. Lymphadenectomy showed 3 positive pelvic/obturator lymph nodes. No prostatectomy was done and no physician TNM staging documented. Do we need a specific clinical description of other organs to which the prostate is fixed in order to code CS Clinical Extension 50, or does the statement "hard, fixed prostate" qualify? If not, how would we code extension for this seemingly advanced cancer? |
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 extension code 50 [extension or fixation to adjacent structures] based on the term "fixed." Fixation to a particular structure(s) does not have to be specified in order to use code 50. Do not use the statement "hard" to determine CS extension. |

20180014 | Reportability/Histology--Brain and CNS: Is multinodular and vacuolating neuronal tumor of the cerebrum reportable, and if so, is the histology coded as 9492/0? See Discussion. |
Patient diagnosed with multinodular and vacuolating neuronal tumor of the cerebrum. My research shows: Multinodular and vacuolating neuronal tumor of the cerebrum is a recently reported benign, mixed glial neuronal lesion that is included in the 2016 updated World Health Organization classification of brain neoplasms as a unique cytoarchitectural pattern of gangliocytoma. There is no code in ICD-O-3 for it, so do I report it and use 9492/0 or not ? |
Do not report multinodular and vacuolating neuronal tumor of the cerebrum. At this time, WHO is undecided about whether this is a neoplastic or a hamartomatous/malformative process. If WHO makes a determination that this is a neoplastic process, we will update reportability instructions and ICD-O-3 guidelines for registrars. |

20081043 | MPH rules--Rectum: How is the number of primaries to be determined when a treatment plan has been completed, but it is not possible to determine whether there was a disease-free interval between occurrences? See Discussion. | Patient diagnosed with adenocarcinoma of the rectum in March 2006, underwent chemo and radiation therapy as treatment. Patient seen in April 2007 for surveillance colonoscopy. HPI stated patient underwent chemorad with good results. Colonoscopy showed "persistent" disease. Abdominal perineal resection was done in May 2007. Path showed adenocarcinoma of the rectum. Keeping in mind that we are not to use a clinical statement for determining recurrences, is the April 2007 occurrence counted as a new primary? |
For cases diagnosed 2007 or later: Do not abstract the 2007 events as a new primary. "Persistent disease" indicates there was never a disease free interval. |

20130086 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are accessioned when a patient is diagnosed in 2008 with chronic myeloid leukemia, chronic phase and is subsequently diagnosed with both accelerated phase (2010) and blast crisis of CML (2012)? See Discussion. | Patient diagnosed in 1/2008 with CML, Chronic phase and had a complete remission following treatment.
In 3/2010 the patient was diagnosed with CML, Accelerated phase and again had a complete remission following treatment.
In 02/2012 the patient was diagnosed with CML, Blast crisis.
How do chronic and acute neoplasms (Rules M8 - M13) relate to histologies that are stated to have Chronic, Accelerated and Blast phases per the Heme DB? These histologies don't change, does this mean Rules M8 - M13 do not apply because there isn't a change in histology? How many primaries should be accessioned in this case? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
This case is accessioned as a single primary, chronic myeloid leukemia, NOS [9863/3] diagnosed 01/2008 per Rule M2. The patient was diagnosed with CML, NOS [9863/3] in 2008 and again in 2010 and 2012. Abstract a single primary when there is a single histology.
CML, Chronic phase; CML, Accelerated phase; and CML, Blast phase (Blast crisis) are listed under the Alternate Names section for CML, NOS in the Heme DB.
Not all histologies have transformations. If a transformation is not listed in the Heme DB, Rules M8 - M13 do not apply.

20130032 | Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for plasma cell myeloma with radiologic evidence of multiple lytic lesions? See Discussion. | Patient complained of pain in the right side and back right upper flank area. CT shows an anterior mediastinal mass and abnormal appearance of skeleton. CXR: Age indeterminate T8 compression fracture. CT chest: abnormal appearance of skeleton. Correlate clinically for myeloma or mets. Acute T5 or T8 compression fractures. Anterior mediastinal mass which may represent thymoma, lymph nodes or metastases. 03/22/12 Metastatic Series: Nonspecific hypodensities in pelvis, left hip and right acromion. Possibility of myeloma can't be totally excluded. Bone marrow right post iliac crest core biopsy, clot section and aspirate: plasma cell myeloma.
Should the primary site be coded to the bone marrow because the diagnosis of plasma cell myeloma was supported by radiologic evidence of multiple lytic lesions? The bone marrow biopsy confirmed the radiology reports. |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C421 [bone marrow] per the Heme DB and Rule PH30. The Primary Site(s) section in the Heme DB indicates the primary site for plasma cell myeloma is C421 [bone marrow].
The Primary Site Coding Instructions in the Heme Manual (Rule 1) states that when a specific code is listed under the Primary Site(s) section of the Heme DB it is the only primary site code that can be assigned for that leukemia, myelodysplastic syndrome or myeloproliferative syndrome. Applying the PH Rules will result in the same answer for primary site, bone marrow [C421].

20081141 | MP/H Rules--Lung: How do we interpret 'spiculated opacities?' How many primaries do we abstract for this patient? See Discussion. |
Patient admitted for CT scan of chest. Impression: A small subpleural spiculated opacity is noted in the left upper lobe measuring 9.7x7.7mm. Right upper lobe spiculated nodular opacity measures 13.9x5.9mm. Right lower lobe scattered faint alveolar nodular opacities are noted. The lungs are otherwise clear. Abnormal soft tissue density mass is noted of the right hilum surrounding the distal main right pulmonary artery. Bronchoscopy/mediastinoscopy done: rare malignant cells present consistent with small cell carcinoma, specimen submitted as brushing of right bronchus intermedius. The tumor in the lymph node is metastatic small cell carcinoma. Patient discharged to hospice; died 5 weeks later. Do the MP/H rules pertain only to the measured opacities in each lung and not to the RLL scattered faint alveolar nodular opacities? The right side was cytologically confirmed. But if we abstract the left lung, what is the histology...8041 or 8000? |
For cases diagnosed 2007 or later: Because there was cytologic confirmation of cancer, for this case only count the spiculated opacities as tumors. Abstract as a single primary using Rule M1. Note 2 under lung rule M1 applies to this case. Code the histology as 8041 [small cell carcinoma] per rule H10. |
