For example:

-ultrasound of the right eye: consistent with a nevoma/melanoma; we could not find any indication that nevoma is a reportable term

-bladder biopsy pathology report:  severe urothelial dysplasia/carcinoma in situ (CIS)

As a central registry, we receive some limited information cases like this where there is no record of treatment or possibility to follow-back to physicians for clarification, so we want to make sure we are reporting them correctly.

IMC-A12 (Cixutumumab) is listed as a BRM agent in SEER*Rx, but the Remarks section indicates it should be coded as Other Therapy until there is FDA approval. It is unclear if FDA approval was ever given for this agent. We are mainly seeing it given for prostate primaries.

A conjunctival biopsy final diagnosis is squamous mucosa with moderate to high grade dysplasia. The diagnosis comment states that immunostains were performed and confirm squamous histology. This seems to imply a high grade squamous dysplasia, rather than a non-reportable high grade dysplasia.  Does this case meet the criteria for reportable high grade squamous dysplasia?

Patient had a partial nephrectomy with final diagnosis of papillary renal neoplasm with reverse polarity.  Diagnosis comment states: Papillary renal neoplasm with reverse polarity is currently considered to be a histologic variant of papillary renal cell carcinoma; however, recent studies suggest that it has a very indolent clinical behavior.

The pathology report states this is a rare entity described in case reports and not incorporated into the WHO classification of tumors. A subsequent endocrinology note stated “papillary tumor, benign by path; tumor was not an adenoma; based on one Mayo study, the recurrence risk is low.”

A 17 year old exchange student was brought into the hospital with appendicitis.  The patient had an appendectomy; there was no follow up treatment.  5/27/2006 pathology report of vermiform appendix:  Adenocarcinoid appendix <5 mm tumor limited to appendix.

The patient has no record in Lexis Nexus and no social security number.  The address is a post office box; additionally, the patient’s birthplace is Switzerland and is lost to follow up.

Laterality is often not noted for these sella turcica meningiomas; therefore, Laterality is often coded as 9 (Unknown). Because the sella turcica appears to be a midline structure in the base of the skull, is Laterality code 5 (midline) more appropriate when additional information is unavailable?

The SEER Manual states that the Other Therapy data item identifies treatments given that cannot be classified as surgery, radiation, systemic therapy, or ancillary treatment; and the instructions for code 2, Other-Experimental, say to assign this for any experimental or newly developed treatment, such as a clinical trial, that differs greatly from proven types of cancer therapy.  Does this mean that only unclassifiable treatments should be coded in Other Therapy, even if given as part of a clinical trial? 

For example, if a patient is given a drug as part of a trial that is categorized in SEER*Rx as immunotherapy, should it be assigned both Immunotherapy (NAACCR #1410) code 1 and Other Therapy code 2, or only coded in Immunotherapy since it is classified as such?  How should a clinical trial drug be coded if it has a treatment classification in SEER*Rx, but the type of cancer being treated is not listed under the Primary Site or Remarks sections as being FDA approved?  A real case scenario is atezolizumab given for colon cancer as part of a trial; this drug's category is Immunotherapy in SEER*Rx but colon is not listed under Primary Sites or in the Remarks detailing FDA approvals.

Patient has a 2021 left parotidectomy showing myoepithelial carcinoma ex-pleomorphic adenoma.  Is this coded to myoepithelial carcinoma (8982/3) or carcinoma ex-pleomorphic adenoma (8941/3)?  It is unclear how to arrive at the correct histology code using the current Solid Tumor Rules.
