Performance Comment

Significance Analysis of Microarray (SAM) was used to develop a 7-gene classifier. The overall prediction accuracy and sensitivity is 71% and 76%, respectively. The inclusion of the Gleason sum to the seven-gene classifier raised the prediction accuracy and sensitivity to 83% and 76% respectively This prognostic signature is closely associated with biochemical recurrence in patients after radical prostatectomy. The seven genes are: RRAGD, PQBP1, HIST1H2BC, ALDH1A2, TRIM22, RBPMS, HSPB8.
