Objective:
To determine whether a short interval (≤2 weeks) between 12-core prostate biopsy and laparoscopic radical prostatectomy (LRP) affects perioperative parameters and the outcome of surgery.
Methods:
This retrospective study included 102 cases of prostate cancer treated by LRP after 12-core prostate biopsy from January 2012 to December 2016. Based on the interval between prostate biopsy and LRP, we divided the patients into three groups: ≤2 wk (n = 35), >2-6 wk (n = 21), and >6 wk (n = 46). The patients averaged 69.87 (59-84) years in age, 24.99 (15.62-33.14) kg/m2 in the body mass index (BMI), 24.41 (0.41-111.78) μg/L in the baseline PSA level, 56.05 (15.97-216.52) ml in the prostate volume, and 7.51 (6-9) in the Gleason score. We analyzed the clinical data, perioperative parameters and outcomes of surgery, and compared them among the three groups of patients.
Results:
Operations were completed successfully in all the 102 cases without transferring to open surgery. There were no statistically significant differences among the three groups of patients in age, BMI, baseline PSA level, prostate volume, Gleason score, or T stage, nor in the operation time, estimated intraoperative blood loss, blood transfusion rate, intestinal injury, positive incision margin rate, or urinary continence rate at 3 months after surgery.
Conclusions:
Laparoscopic radical prostatectomy at ≤2 weeks after 12-core prostate biopsy is safe and effective in the treatment of prostate cancer and does not affect the perioperative parameters and outcomes of surgery.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
