Reportability/In Situ--Prostate: Was there a time period when PIN III was reportable to SEER?
Per the 2004 SEER Manual, page 2, Reportable Diagnoses, Exceptions, 1.b.iii "Prostatic intraepithelial neoplasia (PIN III) of the prostate (C619). (Collection stopped effective with cases diagnosed 1/1/2001 and later.)"
Reportability--Heme & Lymphoid Neoplasms: Is refractory iron deficiency anemia reportable?
Per Appendix F, refractory iron deficiency anemia is not reportable. It is not a clonal disorder and, therefore, is not malignant. Refractory iron deficiency anemia is a condition that is unresponsive to oral iron treatment.
Multiple Primaries--Urinary: How many primaries should be coded for an 8/9/07 invasive transitional cell carcinoma of right ureter; 7/9/08 non-invasive urothelial carcinoma of bladder; 11/18/08 non-invasive urothelial carcinoma of left ureter; 6/20/09 invasive urothelial carcinoma of left ureter?
One primary. This is a good example of how the field effect occurs in the urinary system. From 2007 to 2008, Rule M8 says bladder and ureter tumors are not new primaries and would be documented as recurrences. Because other urinary sites are involved by 11/08 and by 06/09, do not make second primary of left ureter (Rule M4 does not apply).
2004 SEER Manual Errata/Grade--Breast: Are the codes on page 94 of the SEER manual's Breast Grading Conversion Table requiring conversion of nuclear grades 1/3 and 1/2 to code 1, 2/3 to code 2, and 2/2 and 3/3 to code 3 correct or are the codes on page C-473 in the Three-Grade System (Nuclear Grade) for breast correct that requires conversion of the same examples to codes 2, 3, and 4 respectively?
On page C-473: Delete the section titled "Three-Grade System (Nuclear Grade)" and delete the table. Use the tables on pages 94 and C-472 to code grade for breast cancer. This correction will be made in the next errata.
MP/H Rules/Histology/Ambiguous terminology: Can synonyms of listed terms, such as "variety" for the list termed "type," be used to code a more specific histology? See Discussion.
The list of terms denoting a more specific histology does not include "variety." During MP/H training sessions there was an emphasis placed on only using terms listed to code a more specific histology. However, the results of an audit indicated that because "variety" is a synonym for "type" it could be used to code a more specific histology. Are synonyms of listed terms to be used to code histology?
No. Synonyms of listed words used in the MP/H rules (e.g., "variety" for the listed term "type") cannot be used to designate a more specific histology.
Grade, Differentiation--Breast: Does SEER agree with our pathologist who contends that "by convention lobular carcinoma is considered to be grade 2"?
No. SEER does not have a default grade code for lobular carcinoma. Code the grade as stated in the pathology report. If no grade is stated, code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable].
Reportability--Skin: Is a pilomatrix carcinoma of the skin reportable if it is described as being a malignant diagnosis based on poor circumscription, infiltrative growth pattern, and focal abundant mitoses?
No. Pilomatrix carcinoma is not reportable to SEER. Please see page 1 of the 2004 SEER manual. Skin primaries with histology codes from 8090 to 8110 are not reportable. Pilomatrix carcinoma is coded 8110/3.
First Course Treatment--Lymphoma: Should the use of proton pump inhibitors be coded as treatment for lymphoma primaries in patients with H Pylori?
No, do not code proton pump inhibitors as treatment. These are used for gastric acid suppression. Proton pump inhibitors are used to treat symptoms, not the lymphoma itself.
