Neoplasia: Grading Systems Flashcards
(14 cards)
This is the degree of cell differentiation and mitotic activity on histology
Grading
What are the general grading ranges of tumor cells?
Low-grade, high-grade, and undifferentiated.
This is the degree of invaion and spread from the initial site.
Staging
This is the meaning of TNM Staging system?
Primary Tumor Size/Invasion
Regional Lymph Node Metastasis
Distant Metastasis
What and how many are the stages in T on the TNM System?
1 (Small)
2
3
4 (Extra Large)
What and how many are the stages in N on the TNM System?
0 (No Lymph Node Development
1
2
3 (Many Development)
What and how many are the stages in M on the TNM System?
0 (Non-Spread)
1 (Spreading)
Between staging and grading, what has more prognostic value?
Staging
This is the classification based on a grading on differentiation of cells resembling normal cells and undifferentiatied cells are in younger or anaplastic forms.
Brooder’s Classification
In Brooder’s, what are the grading and their corresponding differentiation?
1 (100-75%)
2 (…)
3 (…)
4 (25-0%)
In Brooder’s, what are the grading and their corresponding undifferentiation?
1 (25-0%)
2 (…)
3 (…)
4 (100-25%)
This is a classification wherein the staging corresponds to the location of the cancer.
Seer Scale
In Seer Scales, this is the stage and its corresponding location and characteristics.
1 (In-Situ; Small Microscopic)
2 (Localized; Developed No Spread)
3 (Regional; Late Stages, Spread Benign Growth)
4 (Distant; Metastastatic Spread)
Unknown (Not Defined)
This is the number staging and it’s correcspondig characteristics.
0 (No Cancer)
1 (Small and Localized)
2 (Large and may spread)
3 (Detectable; Spread via Lymph)
4 (Spread to Other Areas; Secondary or Metastatic)
