11/01/2018, lung, left upper lobe, wedge resection: Invasive moderately differentiated adenocarcinoma, predominantly papillary subtype, with minor acinar and lepidic subtypes. Would this be 8260/3 since the acinar and lepidic subtypes are described as minor or would this be 8255/3 because there is papillary plus two other subtypes/variants described as subtypes?

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.

Patient has a 1.7 cm encapsulated papillary carcinoma staged as pTis located 2 cm from the nipple and Paget disease of the nipple on mastectomy pathology.

There is no indication in Table 3: Specific Histologies, NOS/NST, and Subtypes/Variants that encapsulated papillary carcinoma is a subtype of ductal carcinoma. Rule M8 notes that if the histology of the underlying tumor is any histology OTHER THAN duct or subtypes of duct, one should continue through the rules. But if M9 applies to this case, then incidence reporting will be increased in comparison to prior years.

Pathology reads: 1. FNA left groin lymph node tissue (smears and cell block): B-cell lymphoma, low grade. The concurrent flow cytometry (3-FC-16-288) identifies a monoclonal B cell population with immunophenotype of CD10++, CD5-, CD23-, CD20++ and unusual CD19-. Overall findings favor follicular lymphoma. FNA Specimen Adequacy: Evaluation for specimen adequacy: Immediate cytology smear review for specimen adequacy was performed at the time of the FNA procedure by pathologist. Smears reviewed from 2 passes in one reading. The specimen was adequate cytological evaluation. Surg Path Final Report Special Studies Immunohistochemistry (CD45, MCK, CD20, CD3, CD10, Bcl6, MUM1 \T\ Ki67) was performed on block 1A to confirm the diagnosis. All controls show appropriate reaction. Lymphoma cells are positive for CD45, CD20, CD10 and weakly positive for bcl6(+) and MUM1(+/-), and negative for MCK. CD3 highlights few T lymphocytes. Ki67 labeling index is low, less than 10%. The immunoprofile supports above diagnosis. Chromosomal study for t(14;18) translocation will be performed, and an addendum report will follow. Flow Final Report Comment: The lymphoma appears to be derived from germinal centre B cells. Together with the findings from the lymph node biopsy (3-FN16-416), follicular lymphoma is favored. However, negative CD19 and CD22 are unusual.

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?

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)

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.
