20180088 | Solid Tumor Rules (2018)/Multiple primaries--Prostate: How many primaries are abstracted and what M Rule applies when a patient is diagnosed with prostate adenocarcinoma in 2014, followed by liver mass biopsy showing neuroendocrine carcinoma, small cell type of the prostate in 2018? See Discussion. |
The patient has a history of prostate adenocarcinoma with lymph node metastases, status post prostatectomy and treatment by Lupron in 2014. The most recent prostate serum antigen measurement (April 2018) was normal. CT scan of the abdomen and pelvis revealed new hypodense liver lesions, a slightly enlarging lung right lower lobe nodule, and enlarging lobular mass in the prostatectomy bed. The core liver biopsy contains areas of metastatic tumor with a differential diagnosis on pathology of high-grade neuroendocrine carcinoma of the prostate (small cell type), which may have been seen in association with prostate adenocarcinoma, or metastatic small cell carcinoma of a different site. Clinically, the physician impression is that this represents metastatic castration-resistant prostate cancer. The Solid Tumor Rules note that the Multiple Primary Rules are not used for tumor(s) described as metastases. However, SINQ 20130221 indicates that, at least historically, these would have been accessioned as multiple primaries (histology 8140 & 8041 per Rule M10). Does the previous SINQ note still apply to these types of cases, and if so how would one know to move beyond the initial note indicating metastases are not new primaries? |
The guidance provided in SINQ 20130221 still applies. Accession two primaries, adenocarcinoma [8140/3] of the prostate [C619], followed by small cell (neuroendocrine) carcinoma [8041/3] of the prostate [C619] for each of the examples given per Rule M10 of the 2018 Solid Tumor Rules, Prostate. In each case, the second histology (because it is not adenocarcinoma) is a new prostate primary. Small cell carcinoma and small cell neuroendocrine carcinoma are not adenocarcinomas. As a result, they are not covered by Rule M3. For the case described in this SINQ submission, based on the findings of a lobular mass in the prostate bed, this is a second primary (there is residual prostatic tissue). This is unchanged from the 2007 Multiple Primaries Rules for Other Sites. |

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. |

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. |

20180095 | Solid Tumor Rules (2018)/Histology--Lung: How is histology coded when the term "predominant" is used to describe solid adenocarcinoma, acinar adenocarcinoma, etc.? Pathology reports often say "See Synoptic" (also known as the College of American Pathologists (CAP) protocol) included in the Final Diagnosis rather than including all the detail. Based upon the new Solid Tumor Rules for lung, predominant/predominantly is no longer a subtype/variant and should not be coded unless there is a specific code/subtype-variant for the NOS in Table 3, e.g., adenocarcinoma, lepidic predominant. See Discussion. |
Examples Example #1: CAP histology type: Adenocarcinoma, solid predominant, Final diagnosis states that Adenocarcinoma, poorly differentiated, solid predominant (80%) and cribriform (20%) subtype (see lung carcinoma synoptic report) Example #2: CAP histology type : Invasive adenocarcinoma, solid predominant, Other Subtypes Present (specify subtype(s), may also include percentages): acinar (45%) and micropapillary (5%) Final diagnosis : adenocarcinoma of the lung, please see Synoptic Report Example #3: CAP histology type: Adenocarcinoma, acinar predominant , Adenocarcinoma, solid predominant Final diagnosis: Adenocarcinoma, poorly differentiated, solid predominant (60%), papillary (30%) and acinar (10%) subtype (see lung carcinoma synoptic report) |
The lung H rules and tables have been updated to include histologies that CAP identifies using the term "predominant" in the diagnosis. Example: Code adenocarcinoma, lepidic predominant, to 8250/3 rather than 8140/3. When the final pathology diagnosis includes more than one "predominant" adenocarcinoma subtype such as acinar, solid, or lepidic, then code the type with the greatest percentage according to Lung Solid Tumor Rule H7. |

20180070 | Solid Tumor Rules (2018)/Histology--Lung: The Histology coding guidelines for lung cancer state to code histology when stated as type or subtype but not to code when described as pattern. How should the histology be coded (Adeno, NOS or Adeno, Mixed subtypes) if the College of Americal Pathologists Protocol of the pathology report lists the following: Histologic type: Adenocarcinoma, papillary (90%), lepidic (8%), and solid (2%) patterns? |
The term/modifier "patterns" is no longer allowed to code a specific histology according to the Lung Solid Tumor H rules. Disregard the papillary, lepidic, and solid patterns and code histology to adenocarcinoma, NOS (8140/3). |

|
20180065 | Immunotherapy: Is immunotherapy ever palliative treatment according to any oncologists or SEER? |
Any treatment that destroys or modifies cancer tissue should be recorded as the appropriate type of treatment -- chemo, immuno, etc. Even if immunotherapy is given for symptoms/palliative treatment, it is likely to kill off tumor cells. |

20180029 | Reportability--Skin: Is early/evolving lentigo maligna reportable? |
As of 01/01/2021, early or evolving melanoma in situ, or any other early or evolving melanoma, is reportable. |
2018 | |
|
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. |

20180108 | Solid Tumor Rules (2018)/Histology--Lung: What is the correct histology of a lung mass with a CT-directed fine needle aspirate "positive for malignancy, favor squamous cell carcinoma. See Discussion. |
Immunostain results of the malignant cells show strong staining with p63 and negative staining with TTF-1 and Napsin. Rare cells stain with CK7. Findings are most compatible with squamous cell carcinoma. The patient is treated as if he has squamous cell carcinoma. The new histology coding rules say you cannot use ambiguous terms which modify the histology to code the histology. So is this 8010/3? |
Code histology to SCC. The lung rules were updated 10/12/2018 to include clarification on using ambiguous terminology to code histology. See page 32. Note 2: Histology described by ambiguous terminology is coded when a case is * Clinically confirmed by a physician (attending, pathologist, oncologist, pulmonologist, etc.) * Patient is treated for the histology described by an ambiguous term Your case meets both of these criteria so code histology to SCC. |

20180109 | Date of diagnosis/Ambiguous terminology--Cervix Uteri: Is the date of diagnosis of a cervical pap smear done in December 2017, that states high-grade squamous intraepithelial lesion with features suspicious for invasion, followed by a cervical biopsy in 2018 positive for squamous cell carcinoma, in 2017? Is the ambiguous term used in the cytology in 2017 (suspicious for invasion) to determine diagnosis as the SEER manual states to use the ambiguous cytology as the date of diagnosis if confirmed later. |
Based on the information provided, this is a 2018 diagnosis. SEER has been asked to postpone implementing the instruction about using the date of the ambiguous cytology until 2019 or later. We will be removing that instruction from the draft 2018 SEER manual when it is finalized. |
