Study Notes
Cancer Staging
- TNM stands for Tumor, Node, and Metastasis, used in cancer staging.
Cancer Progression
- In stage III, the tumor extends to nearby places and lymph nodes.
Survival Rate
- The 5-year survival rate for T1 stage cancer is not specified in the text.
Hodgkin's Disease Staging
- Stage II in Hodgkin's Disease staging indicates the cancer is found in two or more lymph node areas on the same side of the diaphragm.
Cancer Staging
- Stage 0 in cancer staging indicates carcinoma in situ, meaning the cancer is still in its original place and has not invaded nearby tissues.
Tumor Differentiation
- Grade 1 in tumor differentiation indicates a well-differentiated tumor, meaning the tumor cells resemble normal cells and the tumor grows slowly.
- In the Prostate Gleason grading system, the degree of differentiation is determined by the two most common patterns of cells in the tumor sample.
- Grade 3 in tumor differentiation is characterized by moderately differentiated tumor cells, which are more abnormal than Grade 1 cells.
- The highest grade in tumor differentiation is not specified in the text.
- In the Prostate Gleason grading system, Grade 5 indicates poorly differentiated tumor cells, which are highly abnormal and grow quickly.
