Grade, Differentiation--Brain and CNS: Can grade IV be implied for brain primaries with the histology of glioblastoma multiforme, even if there is no statement of grade in the path report? See discussion.
Dr. Platz has instructed the Iowa registry to code glioblastoma multiforme to grade IV, even when there is no corroborating statement of grade in the path report. This is also supported in some references.
Code the Grade, Differentiation field to 9 [Cell type not determined, not stated or not applicable] in the absence of a stated grade on the pathology report. If a grade is stated, code the stated grade. SEER does not recommend adopting the rule in the Discussion.
Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)?
Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site.
Grade, Differentiation--All Sites: Should we take the grade from a TNM staging form over a grade stated in a pathology report when the grade mentioned on the TNM staging form is a higher grade (e.g., Pathology report diagnosis is moderately differentiated adenocarcinoma, Gleason's 3+3=6, but the physician checked "poorly differentiated" on the TNM form)?
Code the Grade, Differentiation field to 2 [moderatley differentiated]. Code from the pathology report over the TNM staging form. If you do not have access to the path report, use the grade from the TNM form.
Grade, Differentiation--All Sites: What code is used to represent this field when a pathology report describes a tumor as a low grade neoplasm consistent with a specific histologic type (e.g., Low grade neoplasm consistent with carcinoid)?
Code the Grade, Differentiation field to 2 [Low grade].
EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Cervix: What codes are used to represent these fields for a cervix primary when the only information on lymph nodes is a CT of the pelvis showing "pelvic adenopathy" (no surgery was done)?
Code the EOD-Lymph Nodes field to 9 [unknown]. Code the Pathologic Review of Number of Regional Lymph Nodes Positive field to 98 [No nodes examined] and the Lymph Nodes Examined to 00 [No nodes examined] because there was no resection of the primary organs. Adenopathy, NOS, per SEER guidelines, is not coded as lymph node involvement
Diagnostic Confirmation: Is it appropriate to code this field to "radiography" confirmation when a CT scan does not actually contain a diagnosis of malignancy, however, the discharge diagnosis in the medical record of "probable malignancy" is likely based on the abnormal CT findings? See discussion.
10/1/02 CT of Chest: 1) Huge (left) suprahilar mass. 2) Moderate volume loss, left lung. Appearance suspicious of LLL collapse. An infiltrate is seen in the aerated upper lobe as well as pleural effusion. 3) Streaky and nodular changes are noted at the right base that may represent possible lymphangetic spread of tumor.
Code the Diagnostic Confirmation field to 7 [Radiography]. This is appropriate because it was the scan evidence that was used to make the clinical diagnosis.
Diagnostic Confirmation--Prostate: How do we code this field when there is an elevated PSA, no other work-up and there is a clinical diagnosis of adenocarcinoma?
Code the Diagnostic Confirmation field to 5 [positive laboratory test/marker study] to indicate the diagnosis is based upon an abnormal PSA tumor marker if the physician uses the PSA as a basis for diagnosing prostate cancer.
Diagnostic Confirmation--Testis: How do you code this field when a testicular mass is confirmed to be cancer on physical exam and testicular antigen, but the orchiectomy specimen was negative and yet the final signout diagnosis on the medical record was "testicular cancer"?
Code the Diagnostic Confirmation field to 5 [Positive laboratory test/marker study] because the disease was confirmed both clinically and by a positive marker. Code 8 [Clinical diagnosis only] is used when the diagnosis is based on information other than that coded in 5, 6, or 7 [positive lab test/marker study, visualization, and radiography or other imaging techniques]. Code 8 is rarely used.
Date of Diagnosis: If an originally diagnosed "benign" tumor is later discovered to have "metastasized", should the date of diagnosis be back-dated to the date the original tumor was discovered or to the date the metastatic disease was identified?
Code the Date of Diagnosis field to the date the malignancy is diagnosed. If there was a medical or pathologic review of the original benign diagnosis that indicates that the patient had cancer at the earlier time, then the earlier date is coded as the date of diagnosis. If no medical or pathologic review of the original benign diagnosis is done, then code the date of diagnosis to the date the metastasis is discovered.
Date of Diagnosis: How do you code this field when the pathologic confirmation is delayed for 2 months because the clinician decides to "watch and see what happens" to a CT identified mass thought to be either a "metastasis from a previously diagnosed malignancy or a new primary"?
Code the Date of Diagnosis field to the date of the scan. This is the earliest date that a recognized medical practitioner said the patient had cancer. The diagnosis on the CT scan was a malignancy. The only question was whether the mass on the scan was metastatic or a primary.
