20180032 | Reportability--Appendix: Is low grade appendiceal mucinous neoplasm (LAMN) reportable for 2018? It is staged as pTis(LAMN) AJCC 8th ed by pathologist. |
Low grade appendiceal mucinous neoplasm (LAMN) is not reportable in 2018. See page 6, https://20tqtx36s1la18rvn82wcmpn-wpengine.netdna-ssl.com/wp-content/uploads/2018/02/2018-ICD-O-3-Coding-Table-Alpha-order-.pdf. Use cancer registry reportability instructions to determine reportability. Do not use the AJCC TNM manual to determine reportability. |

20180035 | Solid Tumor Rules (2018)/Multiple Primaries--Lung: How many primaries should be abstracted in this 2018 lung case? See Discussion. |
CT chest findings: 1. There is a dominant 1 cm. nodule in the left mid lung. 2. In addition, there is a new rather dominant bilobed nodule in the left lung base. 3. Distant metastases are not identified. Four months later, a doctor's note says routine follow-up visit status post Cyber Knife stereotactic body radiation therapy for synchronous early stage non-small cell carcinomas of the left upper and left lower lobes, both Stage IA. He is medically inoperable. This situation is described as a second primary tumor in AJCC8 page 438. However, by the 2018 Lung Solid Tumor rules, this would be a single primary, per rule M7. Is that correct? |
Abstract one primary per Rule M7. Follow the Lung Solid Tumor Rules to determine the number of primaries. The AJCC TNM manual is used for staging. Do not apply AJCC instructions to determine the number of primaries. |

20180094 | Reportability--Prostate: According to the 2018 SEER Program Manual, a prostatic intraepithelial neoplasia (PIN) III is not reportable, but is an atypical small acinar proliferation (ASAP) PIN 4 reportable? |
ASAP is not reportable. Patients with ASAP found on needle biopsy will likely undergo another biopsy. |

20180096 | Reportability/Histology--Small intestine: Is a neuroendocrine microtumor of the duodenum a reportable tumor? See Discussion. |
This comment was added to the pathology report by the pathologist: A focus of neuroendocrine microtumor measured 350 micrometers, qualifying as a neuroendocrine microtumor. Focus was immunohistochemically positive for chromogranin and synaptophysin and negative for gastrin. The Ki-67/CD45 immunostain showed <1% positivity in microtumor. |
Neuroendocrine microtumor of the duodenum is reportable as 8240/3. "Microtumor" pertains to the size/amount of NET and not to a histologic type. |

20180104 | Reportability--Ambiguous terminology: Are the following terms reportable: almost certainly and until proven otherwise? See Discussion. |
Example 1: Physician states patient has an almost certain melanoma. Due to the patient's age, there is no plan to for any treatment or further workup. Almost certain is not listed as a reportable phrase, so typically we would not accession this case. Example 2: Imaging states a diagnosis of renal cell carcinoma until proven otherwise. No additional workup is available at this facility. This terminology is also not seen on the ambiguous reportable terminology list but we are seeing it more often and wanted confirmation. |
Use the ambiguous terminology list as a last resort. Consult with the physician and search for further information to assist with the decision. If no further information can be obtained, use the ambiguous terms list to decide; in this case, the terms are not on the list and these examples would not be reportable. |

20180021 | Solid Tumor Rules (2018)/Histology--Corpus uteri: What is the correct histology code for "Mesophrenic-like adenocarcinoma" of the corpus uteri?" See Discussion. |
The article I read (https://www.ncbi.nlm.nih.gov/pubmed/?term=28984674) makes the distinction between mesophrenic adenocarcinoma and mesophrenic-like adenocarcinoma. The authors propose the term mesonephric-like Mullerian adenocarcinoma. So would this be coded as Mullerian adenocarcinoma? |
Assign code 9110/3, mesonephric adenocarcinoma. These tumors commonly arise in the cervical wall and more commonly involve the lower uterine segment than do other cervical adenocarcinomas. |

20180061 | Primary Site: How should primary site be coded when there is an invasive tumor in one subsite and an in situ tumor in another subsite of the breast? See Discussion. |
The previous SEER Program Coding and Staging Manual included Appendix C that has Coding Guidelines for some sites. The breast guidelines specifically instructed one to code the subsite with the invasive tumor when the pathology report identifies invasive tumor in one subsite and in situ tumor in a different subsite or subsites. The current Breast Solid Tumor Rules Table 1: Primary Site Codes refers one back to the SEER Manual and COC Manual for a source document priority list but does not make mention of invasive vs. in situ on that final version of the source document. In addition, the Colon Solid Tumor Rules currently contains no Site Coding Section/Table. However, the Lung Solid Tumor Rules do and also refer one to the SEER/COC Manuals for document priority lists. The Urinary Solid Tumor Rules has both the Primary Site Codes Table and an additional section called Priority for Coding Primary Site, which does not reference a document priority list or other manuals. Unfortunately, there is additional information in Appendix C Bladder Coding Guidelines that may have been used in the past regarding site source priority. Could the remaining applicable Appendix C information be consolidated into the Solid Tumor Rules consistently among all the sites to lessen the need for additional manual referencing? Also, is there a reason one site includes the Priority Site Coding instructions and others do not? |
Code the subsite with the invasive tumor as the primary site when the pathology report identifies invasive tumor in one subsite and in situ tumor in a different subsite or subsites as stated in Appendix C, Breast Coding Guidelines, 2018 SEER Program Coding and Staging Manual. This statement is unchanged from the previous version; however, the priority list was modified for coding a subsite when there is conflicting information. The focus of the Solid Tumor Rules is to differentiate between single vs. multiple primaries and to assist with identifying the appropriate histology code. The site tables in the solid tumor rules are a reference only. The site-specific Coding Guidelines assist with additional considerations when abstracting cases. |

20180039 | Solid Tumor Rules 2018/Histology--Testis: What is the histology code for a 2018 diagnosis of left testis tumor diagnosed as mixed germ cell tumor with secondary malignant components: primitive neuroectodermal tumor (PNET) and rhabdomyosarcoma? See Discussion. |
The patient has testicular cancer with bilateral lung metastases and possible liver metastasis. The left orchiectomy final diagnosis was The Summary describes a single tumor that is, Germ cell neoplasia in situ (GCNIS) is also present. Although there is mixed germ cell tumor present, the PNET component of the tumor is locally invasive extending into the epididymis, hilar soft tissues, spermatic cord, and tunica vaginalis. The mixed germ cell tumor is limited to the testis only. We are instructed not to use to the term to code histology in the MP/H Rules General Instructions (Other Site Rules not updated for 2018), however the PNET comprises the majority of this tumor and represents the most extensive disease. Should the PNET histology be ignored in this case as its a ? |
Assign code 9084/3. According to our expert pathologist consultant, this is a teratoma with a somatic-type malignancy. This code is the best choice even though it does not capture the mixed germ cell elements of the tumor, or the character of the somatic component (rhadomyosarcoma, PNET).There aren't enough histology code numbers to cover all of the possibilities. Use text fields to describe the specifics of this case. |

20180107 | Solid Tumor Rules (2018)/Histology--Lung: If the pathology states non-small cell carcinoma of the lung (NSCLC), consistent with squamous cell carcinoma, is the code non-small cell carcinoma according to the Solid Tumor Rules? The Medical Oncologist states that the tumor is a squamous cell carcinoma. In these instances would you code the squamous cell carcinoma since you have a definite physician statement? |
Code the histology to SCC 8070/3. Based on registrar feedback on the NSCLC rule, we added a rule that specifically addresses when ambiguous terminology can be used to code histology other than NSCLC. The lung rules were update 10/12/2018 so please make sure you are using the currently posted rules. The new rule is: Rule H3-Code the specific histology when the diagnosis is non-small cell lung carcinoma (NSCLC) consistent with (or any other ambiguous term) a specific carcinoma (such as adenocarcinoma, squamous cell carcinoma, etc.) when: * Clinically confirmed by a physician (attending, pathologist, oncologist, pulmonologist, etc.) * Patient is treated for the histology described by an ambiguous term * The case is accessioned (added to your database) based on ambiguous terminology and no other histology information is available/documented Example 1: The pathology diagnosis is NSCLC consistent with adenocarcinoma. The oncology consult says the patient has adenocarcinoma of the right lung. This is clinical confirmation of the diagnosis, code adenocarcinoma. Your case meets the criteria in bullet 1. |

20180030 | First Course of Treatment/Surgery of Primary Site--Melanoma: How do you code UVB therapy treatment for melanoma? |
Code UVB therapy for melanoma as photodynamic therapy under Surgery of Primary Site for skin. Assign code 11 [Photodynamic therapy (PDT)] if there is no pathology specimen. Assign code 21 [Photodynamic therapy (PDT)] if there is a pathology specimen. Use text fields to document details. |
