Q

What is the term used to describe the trend of diagnosing more advanced stages of prostate cancer, particularly after the Grade D recommendation from the U.S. Preventive Services Task Force in 2012?
A. Direct stage migration
B. Progressive stage migration
C. Inverse stage migration
D. Regressive stage migration

A

C. Inverse stage migration
Explanation: In the context of prostate cancer and the Grade D recommendation from the U.S. Preventive Services Task Force in 2012, the term “inverse stage migration” is used to describe a shift towards diagnosing higher-stage, more advanced prostate cancers. This is likely due to the discouragement of routine prostate-specific antigen (PSA) testing, which might have led to fewer diagnoses of early-stage, lower-risk cancers. Instead, cancers were more likely to be diagnosed when they had progressed to a later stage and were causing symptoms.
