The results of the review were as follows:
The rate of clinical understaging was 46% of patients.
The sensitivity and specificity of MR imaging were 38% and 97% respectively.
Mortality due to surgery was 1% of patients.
The probabilities of impotence and incontinence were 30% and 6% respectively.
The probabilities of treatment for impotence and incontinence were 10% and 50% respectively.
Utility values of impotence and incontinence were 0.95 and 0.85 respectively.
The number of life years with successful and unsuccessful surgical outcome were 14.45 and 10.75 respectively.
The number of life years of no surgery because of T3 and T2 tumour were 10.75 and 12.64 respectively.
MR imaging enhanced clinical staging.
Endorectal coil MR images provided a more accurate prediction of extracapsular disease or seminal vesicle invasion than did clinical staging.
