20190106 | Tumor Size--Esophagus: Can information from the endoscopy procedure that implies a size of 3 cm for Tumor Size--Clinical be used for Esophagus? See Discussion. |
1-28-2018 CT Scan: 2.4 cm mass 2-15-2018 Endoscopy: Mass was present 22 to 25 cm. Biopsies were taken with cold forceps for histology; biopsy positive. |
For the case you describe, we would record the clinical tumor size stated on the CT report. The priority order for clinical tumor size is as follows. 1. Biopsy or operative (surgical exploration) report 2. Imaging 3. Physical exam We do not recommend coding tumor size based on an inferred tumor size from a description such as "Mass was present 22 to 25 cm." Look for an actual measurement of the mass, or a stated tumor size. Use text fields to record details. |

20190022 | Solid Tumor Rules (2018)/Histology--Lung: Is histology code or the number of primaries assigned differently in SINQ 20180093 if the word "pattern' was omitted? See Discussion. |
Regarding the answer to SINQ 20180093: This is a single primary; coded 8140/3 adenocarcinoma. In the biopsy and the two tumors found on lobectomy, the specific adenocarcinoma histologies are described as acinar predominant pattern, solid growth pattern and lepidic predominant pattern. You do not code a pattern, so rule M7 above applies and this is a single primary. My question is based on Note 2 in Coding Multiple Histologies for lung cancers that says: Predominantly describes the greater amount of tumor. Predominant and majority are synonyms. Per the CAP protocol, the term predominant is acceptable for the following specific subtypes of adenocarcinoma. For these subtypes only, the word predominant is used to describe both the subtype and the grade of the tumor. |
If the word "pattern' was omitted, you would abstract multiple primaries per the Lung Solid Tumor Rule M6 and code histology to adenocarcinoma, acinar predominant (8551/3) and adenocarcinoma, lepidic predominant (8250/3) per Rule H4 as the word "pattern' is not included in each histology. |

20190056 | Behavior--Breast: What is the behavior of a solid papillary carcinoma when a pathologist does not indicate it in the pathology report and follow-up with the pathologist to obtain clarification regarding the behavior is not possible? See Discussion. |
Example: Mastectomy specimen final diagnosis shows two foci of invasive ductal carcinoma including: Invasive ductal carcinoma, no special type, in association with solid papillary carcinoma (tumor #1, 1 cm, slices 6 and 7) and invasive ductal carcinoma, no special type (tumor #2, 1.2 cm, slices 9 and 10). Summary Staging outlines, Tumor #1: Histologic Type: Invasive ductal carcinoma, no special type, in association with solid papillary carcinoma. As well as, Tumor #2: Histologic type: Invasive ductal carcinoma, no special type. Additional findings include ductal carcinoma in situ (DCIS): presently approximately 3.3 cm, spanning slices 10-13. The behavior of the solid papillary carcinoma component will affect the provisional histology of the first tumor (8523/3) per Rule H17 vs. 8500/3 per Rule H7). Based on the response, we can determine whether this represents a single or multiple primaries (single primary per M13 vs. multiple primaries per M14). |
Review all sections of the pathology report carefully for any mention of invasion, or lack of invasion, pertaining to the solid papillary carcinoma. Per WHO 4th Ed Breast: If there is uncertainty that there is invasion, these lesions should be regarded as in situ. The distinction between in situ and invasive disease in solid papillary carcinoma is difficult. |

20190105 | Histology--Brain and CNS: What morphology code should be assigned to a low-grade glial/glioneuronal neoplasm? See Discussion. |
Pathology Diagnosis: Left temporal lesion - Low grade glial/glioneuronal neoplasm BRAF mutant. Pathologist Comment: The histopathological appearance of this lesion does not allow for a definitive diagnosis. However, the low-grade appearance, fibrillary nature, immunohistochemical profile, and the presence of a BRAF V600E mutation allow this to be categorized as a low-grade glial or possibly glioneuronal tumor. Despite the lack of exact classification this neoplasm can be expected to behave in a very indolent manner consistent with a WHO grade I classification. |
Assign 9413/0 for glioneuronal neoplasm. We consulted with our expert neuropathologist about the histology "glioneuronal neoplasm." This term is relatively new and has not yet been recognized by WHO or assigned an ICD-O code. Until such time that WHO determines a code for this neoplasm, our expert instructed us to use 9413/0. Since this is not a recognized neoplasm it is not included in the solid tumor rules. |

20190057 | Reportability/Histology--Penis: Are and (PeIN) equivalent to PeIN3 and thus reportable? See Discussion. |
Appendix E1 of the 2018 SEER manual references a similar diagnosis as being reportable for vulva and vagina only. However, the WHO Classification of Tumors of the Urinary System and Male Genital Organs (4th ed) does include high grade penile intraepithelial neoplasia as a synonym for 8077/2. |
Penile intraepithelial neoplasia, grade III (PeIN III) and squamous cell carcinoma in situ of the penis are reportable. If possible, query the physicians as to whether "high grade penile intraepithelial lesion" or are synonymous with one of the reportable terms. If no further information can be obtained, report the case as C609 8077/2, and use text fields to document the details. |

20190107 | First Course Treatment/Chemotherapy--Colon: Is maintenance therapy coded as part of the first course of treatment or as part of subsequent course of treatment? |
Patient was diagnosed with Stage IV colon cancer (liver metstasiss) and started on Folfox with Avastin. The medical oncologist decided to continue maintenance treatment with Xeloda and Avastin. Per Colon NCCN Guidelines Version 3.2019, interest in the use of maintenance therapy approach after first-line treatment of unresectable, metastatic colorectal cancer is growing. In general, this approach involves intensive first-line therapy, followed by less intensive therapy until progression in patients with good response to initial treatment. Colon Therapy 5/1/18 Colonoscopy biopsy: mod diff colon adenoca, MMR proficient, BRAF wild type 5/5/18 Liver biopsy: mets from colon cancer 6/18/18 " 11/20/2018 Med Onc: started 12 cycles Chemo - Folfox (Fluorouracil, leucovorin, Oxaliplatin) with Avastin 11/28/18 CT Pelvis: continued improvement in the liver mets; no residual tumor involving colon; no new mas or adenopathy in the chest, abdomen or pelvis 12/02/18 Med Onc follow up: Pt had tremendous response to chemotherapy and Avastin, cancer is not curable. Is amenable to maintenance therapy with Xeloda and Avastin; also amenable to descending colectomy in the future 1/7/19 Med Onc: starting maintenance treatment Xeloda + Avastin. |
Code the maintenance therapy as first course when the maintenance therapy includes at least one of the drugs from the original treatment. Use text fields to record the details. |

20190051 | Update to current manual/Solid Tumor Rules (2018)/Histology--Lung: What is the histology code and what M Rule applies when there are multiple specific subtypes identified using various equivalent lung terms but only one is stated to be predominant? See Discussion. |
Example: Lung resection final diagnosis is Lung adenocarcinoma, see Summary Cancer Data, and the Summary Cancer Data (CAP Synoptic Report) states Histologic type: Invasive adenocarcinoma, solid predominant. Other Subtypes Present: 20% acinar and <5% micropapillary components. Instruction 1B and Note 1 for Coding Multiple Histologies (Lung Histology Rules) indicates type, subtype, component, and predominantly are all terms that may be used to code the most specific histology. In this case, the multiple specific histologies were documented using all of those terms. Note 2 for instruction 1B states predominantly describes the greatest amount of tumor and when it is used for the listed subtypes of adenocarcinoma, that subtype should be coded. However, Note 2 does not indicate that the other subtypes are ignored when one is identified to be predominant and the others are identified as subtype or component only. |
Code to invasive adenocarcinoma, solid predominant (8230/3), based on the example, using Lung Solid Tumor Rules Coding Multiple Histologies instruction #1 that says to code the specific histology where the most specific histology may be described as component, majority/majority of, or predominantly, in this case, 75%. Apply Rule M2 as this appears to be a single tumor with multiple histologies based on the information provided. The rules will be updated to add a new H rule and to reviseTable 2 when two or more histologies described as predominant are present. |

20190036 | First Course of Treatment/Hormone Therapy--Breast: Is hormone therapy (HT) prescribed for invasive ductal carcinoma of the right breast coded as treatment for lobular carcinoma in situ (LCIS) of the left breast even though the treatment plan for the LCIS was documented as surveillance? See Discussion. |
Patient is diagnosed with invasive ductal carcinoma (IDC), right breast, receives HT, radiation therapy, and surgery. The same patient is diagnosed with LCIS, left breast one month later--recommend surveillance only (no surgery). Is the HT for the left breast coded at all? I think for COC/NCCN, we do not, but for SEER what would I do? Treatment in the SEER Manual 2018 states, "Code the treatment on each abstract when a patient has multiple primaries and the treatment given for one primary also affects/treats another primary." The example include bladder/prostate and ovarian/cervix. It also states, "Code the treatments only for the site that is affected when a patient has multiple primaries and the treatment affects only one of the primaries." The example includes colon/tonsil. Breast LCIS treatment appears complicated. Per NCCN guidelines, this condition no longer has recommendations, however it appears as though they still state that if a core biopsy is done and is LCIS, follow up should be ultrasound or surgical excision. Nowhere does it state hormone is recommended. |
Do not code the hormone treatment for the LCIS since it was clearly documented that the hormone treatment was given for the IDC and the treatment for the LCIS was documented as "surveillance." Use text fields to record the details on both abstracts. |

20190066 | Solid Tumor Rules (2018)/Histology--Breast: How is the histology coded for a metastatic carcinoma, consistent with primary breast carcinoma, when no other pathology information is available? See Discussion. |
The 2018 Breast Solid Tumor Rules Equivalent Terms and Definitions - Changes from 2007 Multiple Primaries/Histology Rules states: Mammary carcinoma is a synonym for carcinoma no special type (NST)/duct carcinoma not otherwise specified (NOS) 8500. It will no longer be coded as carcinoma NOS 8010. Should metastatic carcinomas of breast origin be 8500, or is code 8010 (carcinoma NOS) more applicable because histology coding from metastatic sites is not as reliable? |
Code as 8500/3 as it is the only tissue available for this carcinoma associated with a breast primary. Breast carcinoma NST/NOS is now coded as 8500. |

20190065 | Update to current manual/EOD 2018/Summary Stage 2018--CLL/SLL: Can chronic lymphocytic leukemia (CLL) be staged when diagnosed by peripheral blood and no bone marrow biopsy, and observation is employed? See Discussion. |
The physicians do not use the Lugano system as we are instructed to stage chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) as lymphomas. I had always been instructed that this qualifies as "bone marrow involvement," or "diffuse disease," and therefore is a Stage IV. Our experts advise that there is not enough information to code it to bone marrow, but do not elaborate as to whether you can actually code Extent of Disease (EOD), SEER Summary Stage, and AJCC Staging? |
For EOD and Summary Stage: Peripheral blood involvement for CLL (or any lymphoma-but most commonly for CLL) can be coded. This is code 800 for 2018 EOD Primary Tumor, and code 7 for Summary Stage 2018. We have recently received confirmation that peripheral blood involvement only is not enough information to assign AJCC stage; assign code 99 for AJCC Stage Group. We will correct in the 2021 release of EOD so that peripheral blood involvement only will have its own code to derive the appropriate AJCC TNM Stage Group (99). |
