Collaborative Stage for TNM 7 - Revised 11/11/2009 [ Schema ]
CS Site-Specific Factor 7
Percentage of Non-Endometrioid Cell Type in Mixed Histology Tumors
- Note 1: This is a microscopic evaluation of the degree of tumor cell differentiation from surgically removed specimens to define histology grade (G). The higher the grade is the worse the tumor malignancy.
- Note 2: Notable nuclear atypia, inappropriate for the architectural grade, raises the grade to 3.
- Note 3: Serous, clear cell, and mixed mesodermal tumors are high risk and considered Grade 3.
- Note 4: Adenocarcinomas with benign squamous elements (squamous metaplasia) are graded according to the nuclear grade of the glandular component.
|001||Recorded as Grade I or 1|
5% or less of a non-squamous or non-morular solid growth pattern
|002||Recorded as Grade II or 2|
6% to 50% of a non-squamous or non-morular solid growth pattern
|003||Recorded as Grade III or 3|
More than 50% of a non-squamous or non-morular solid growth pattern
Information not collected for this case
