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.
Multiple Primaries (Pre-2007)--Ovary/Endometrium: Is endometrioid adenocarcinoma occuring simultaneously in the left ovary and the endometrium one primary or two? See discussion.
Pathology Final Diagnosis:
Left Ovary: Moderately differentiated endometrioid adenocarcinoma squamous differentiation grade 2 (scale of 3)
Uterus: Moderately differentiated endometrioid adenocarcinoma with squamous differentiation, grade II (scale of III). Focal, very superficial invasion to inner third myometrium with extension to lower uterine segment. Endocervix, cervix, right ovary and fallopian tubes negative for tumor.
For tumors diagnosed prior to 2007:
Code the case you describe as two primaries. The endometrioid adenocarcinoma can arise in the endometrium without a concomitant ovarian carcinoma.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Histology (Pre-2007)--Skin: Are "atypical melanocytic hyperplasia" and "severe melanotic dysplasia" synonyms for melanoma in situ?
For tumors diagnosed prior to 2007:
No. SEER determines its reportable list from the ICD-O-3. The above terms are listed as tumor-like lesions and conditions, but are not in situ or malignant.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
Multiple Primaries/Histology (Pre-2007)--Bladder: What code is used to represent the histology and how many primaries should be coded for a TURB specimen that demonstrates carcinoma in situ, Grade I to II papillary transitional cell carcinoma, and high grade transitional cell carcinoma? See discussion.
Pathology report:
A. Biopsy, bladder neck, @ 6:00: Carcinoma in situ
B. Biopsy, Bladder wall, lateral, left:
1. Papillary carcinoma (Grade I-II)
2. Loose fragments of high-grade transitional carcinoma
C. Biopsy, Bladder neck @ 5:00: Carcinoma in situ
D. Biopsy, Bladder neck @ 7:00: Cystitis Glandularis
E. Biospsy, Bladder wall, posterior: Papillary carcinoma (Grade I)
For tumors diagnosed prior to 2007:
Code this case as one primary and code the Histology and Grade, Differentiation fields to 8130/34 [papillary transitional cell carcinoma, high grade].
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
EOD-Extension/EOD-Lymph Nodes--Kaposi Sarcoma: What code is used to represent this field for a Kaposi sarcoma with no skin lesions but positive lymph node and bone marrow biopsies?
Code the EOD-Extension field to 13 [Visceral (e.g., pulmonary, gastrointestinal tract, spleen, other)], because of the positive bone marrow. Code the EOD-Lymph Nodes field to 3 [Both clinically enlarged palpable lymph nodes (adenopathy) and pathologically positive lymph nodes], for the pathologically positive node.
Note: Potential revision of the extension scheme will be referred to SEER Medical Advisory Group (SMAG).
EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined: What codes are used to represent these fields when only a regional lymph node (positive) aspiration is performed?
For cases diagnosed 1998-2003:
With the exception of those sites/histologies that require 99 in these fields, code the Number of Regional Lymph Nodes Positive field to 97 [Positive nodes but number of positive nodes not specified]. Code the Number of Regional Lymph nodes Examined field to 95 [No regional Lymph nodes removed, but aspiration of regional Lymph nodes was performed].
EOD-Extension--Small Intestine: How do we interpret a pathology description of "extending through serosa and forming masses in the periserosal tissue" for a jejunum primary?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 55 [Invasion of/through serosa and adjacent connective tissue]. The description states the tumor extended through the serosa into periserosal tissue. The periserosal tissue in this case refers to adjacent connective tissue lying exterior to the intestinal wall and not the (sub)serosal tissue that lies exterior to the muscularis but inferior to the serosa. Analyze each case individually since pathologists are not consistent when using the above terminology.
EOD-Extension--Cervix: Should this field be coded to 11 [minimal microscopic stromal invasion] or 12 [microinvasion] when there is only a statement of "microinvasion" but no measurements describing the level of involvement given?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 12 [microinvasion] when there are no depth of invasion measurements given.
Code the EOD-Extension field to 11 [minimal microscopic stromal invasion] when there is a statement of "minimal STROMAL invasion."
EOD-Extension/EOD-Lymph Nodes: Can the AJCC TNM/Stage be used to help code these fields when there is limited text information in the medical record that describes the tumor involvement?
For cases diagnosed 1998-2003:
Yes, this staging information can be used to help code the SEER EOD fields but only if a physician does the TNM/Stage at the time of diagnosis and there is limited text information that describes tumor involvement.
EOD Fields--All Sites: Is EOD information limited to what is available exactly two months from the day of diagnosis?
For cases diagnosed 1998-2003:
EOD should include all information available within four months of diagnosis in the absence of disease progression or through completion of surgery(ies) in first course of treatment, whichever is longer.
Mets known to have developed after EOD was established should be excluded.
