Code OPTUNE in the Other Treatment field. See NovaTTF in SEER*Rx (http://seer.cancer.gov/seertools/seerrx/). NovaTTF is the pre-FDA approval name for OPTUNE.

If OPTUNE was administered for recurrence, be sure NOT to record it in the first course of treatment fields. Check with CoC if you have questions about coding treatment for recurrence.

Primary hepatic neuroendocrine tumor (PHNET) is reportable as are other digestive system NETs. There is no specific histology code for PHNET. We suggest you assign 8240/3. Use text fields to document the details.

Unless you can obtain clarification, do not report primary hepatic neuroendocrine neoplasm with no further information. If this term is being used as a synonym for PHNET, document this in the registry's policies and procedures, and report these cases.

As of 01/01/2021, early or evolving melanoma in situ, or any other early or evolving melanoma, is reportable.

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.

Abstract as multiple primaries using Breast Solid Tumor Rule M12 as these are separate, non-contiguous tumors on different rows in Table 3.

Marital Status is self-reported because the information is recorded in the medical record based on information obtained from the patient. Use text fields to document relevant information.

Examples

1. Assign code 2 for the first tumor and assign code 1 for the subsequent tumor unless the available information indicates the patient is divorced at the time of the subsequent tumor diagnosis. Patient may self-report single after a divorce. Assign code 4 in that situation.

The code assigned for marital status reflects the patient's marital status at the time of diagnosis for the tumor being abstracted. It is possible that marital status may be different for each tumor if the patient has multiple tumors.

2. If marital status is stated to be single, assign code 1.

3. If marital status is stated to be common law marriage, assign code 2.

Common Law Marriage is defined as a couple living together for a period of time and declaring themselves as married to friends, family, and the community, having never gone through a formal ceremony or obtained a marriage license.

Do not report this case based on the information provided. The actual diagnosis is somewhere between atypical hyerpplasia and carcinoma in situ. Do not report until/unless a more definitively reportable diagnosis is made.

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.

Code an allogenic stem cell transplant as 20 (Stem cell harvest (stem cell transplant) and infusion) in Hematologic Transplant and Endocrine Procedures in the 2016 SEER Manual.

For cases diagnosed prior to 2018

Abstract two primaries, Medullary (8510/3) and papillary microcarcinoma (8260/3). Other sites rule M17 applies.
