For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.

The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.

The site of the cancer diagnosis does not change the interpretation.

For solid tumors, ignore the term "evolving" and apply the registry rules for reportability to this case. Squamous cell carcinoma of the vermillion border of the lower lip (C001) is reportable.

For testis, mature teratoma in an adult (post-puberty) is reportable because it is malignant (9080/3); however, mature teratoma in a child is benign (9080/0). The 2011 NAACCR webinar introduced this concept and it was documented in the 2012 SINQ question. You may use 2011 or 2012 as the date of this change. The next edition of the SEER manual will include reportability examples.

For the case described here, use the size from the CT scan. Physical exam includes what can be seen by a clinician either directly or through a scope. A tumor size obtained visually via cystoscopy is part of a physical exam. Therefore, the imaging (CT) tumor size is preferred. Use text fields to describe the details.

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.

For the example provided: For 2023 cases and forward, if no part of the surgery was performed, code Surgery of Primary Site 2023 (NAACCR Item #1291) as code A000 or B000 (no surgical procedure of the primary site).  Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 2 (surgery of the primary site was not recommended/performed because it was contraindicated due to patient risk factors (comorbid conditions, advanced age, progression of tumor prior to planned surgery, etc.).

In contrast, if any part of the surgery was performed, assign the Surgery of Primary Site 2023 (NAACCR Item #1291) code that best reflects the extent of the surgery performed.  Code Reason for No Surgery of Primary Site (NAACCR Item #1340) as code 0 (surgery of the primary site was performed).

Use text fields to record the details.

For cases prior to 2023, apply the same approach using Surgery of Primary Site (NAACCR Item #1290) instead of Surgery of Primary Site 2023 (NAACCR Item #1291).

For the purpose of applying the MP/H rules, the term "synchronous" means that the two diagnoses occurred at the same time or less than or equal to 60 days apart.

The case in SINQ 20100025 was not synchronous. The first lesion in the renal pelvis [C65.9] occurred in 1/08 and the subsequent tumors were diagnosed in 5/09, more than one year apart. In this case, you do not go back to change the primary site code on the original abstract.

The case in SINQ 20110119 was diagnosed synchronously, the first lesion in the bladder [C67.9] was diagnosed in 11/09 and the second lesion in the renal pelvis [C65.9] was diagnosed in 12/09, less than 60 days apart. Because the lesions were synchronous, the primary site is coded urinary system, NOS [C68.9].

For this case only, it is reportable to SEER because the physician states that it is "melanoma in situ."

The phrase "proliferation of atypical melanocytes confined to epidermis" alone is not reportable to SEER. This phrase means that there are a number of (proliferation) pigmented cells (melanocytes) not showing the normal cell structure (atypical).

For this case, assign code C670 [Trigone of bladder]. The description for this case states that the tumor location is the base of the bladder. Base is a synonym for trigone.

The interureteric ridge (or interureteric crest, or interureteric fold) is a fold of mucous membrane extending accross the bladder between the two ureteric orifices. The trigone is located below the interureteric ridge.

For this case, code Date Therapy Initiated to the date of the sentinel lymph node biopsy [04102008]. Assign code 3 [Systemic therapy after surgery] in Systemic/Surgery Sequence.
