2. Grading (tumors) - Wikipedia

   en.wikipedia.org/wiki/Grading_(tumors)

   Cancer is a disorder of cell life cycle alteration that leads (non-trivially) to excessive cell proliferation rates, typically longer cell lifespans and poor differentiation. The grade score (numerical: G1 up to G4) increases with the lack of cellular differentiation - it reflects how much the tumor cells differ from the cells of the normal ...

3. Prostate cancer staging - Wikipedia

   en.wikipedia.org/wiki/Prostate_cancer_staging

   For prostate cancer, cell morphology is graded based on the Gleason grading system. [citation needed] Of note, this system of describing tumors as "well-", "moderately-", and "poorly-" differentiated based on Gleason score of 2–4, 5–6, and 7–10, respectively, persists in SEER and other databases but is generally outdated. In recent years ...

4. Performance status - Wikipedia

   en.wikipedia.org/wiki/Performance_status

   In medicine (oncology and other fields), performance status is an attempt to quantify cancer patients' general well-being and activities of daily life. This measure is used to determine whether they can receive chemotherapy, whether dose adjustment is necessary, and as a measure for the required intensity of palliative care.

5. Active surveillance of prostate cancer - Wikipedia

   en.wikipedia.org/wiki/Active_surveillance_of...

   The rate of death from prostate cancer at 10 years for men age 65–74 years with moderately differentiated cancers (Gleason score 5–7) diagnosed with screening (in the prostate cancer screening era) and pre prostate cancer screening eras (without screening) were from 2-6%, and from 15 to 23%, respectively.

6. Cancer survival rates - Wikipedia

   en.wikipedia.org/wiki/Cancer_survival_rates

   The National Institute of Health (NIH) attributes the increase in the 5-year relative survival of prostate cancer (from 69% in the 1970s to 100% in 2006) to screening and diagnosis and due to the fact that men that participate in screening tend to be healthier and live longer than the average man and testing techniques that are able to detect ...

7. Gleason grading system - Wikipedia

   en.wikipedia.org/wiki/Gleason_grading_system

   The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy. A Gleason score is given to prostate cancer based upon its microscopic ...
