Spots Global Cancer Trial Database for Does End-fire Technique Increase Detection Rate of Prostate Cancer at First Re-biopsy Compared to Side-fire Technique?

Study Description

Brief Summary: Prostate cancer is the most common cancer among men in Sweden. During investigation of suspected cancer transrectal ultrasound with needle biopsies from prostate leeds to diagnosis. The most common technique today is side-fire where the needle enter the prostate in angle from the probe. In end-fire technique the needle enters the prostate at tip of probe without angle. The difference in techniques side-fire vs. end-fire affects the possibility to reach the ventral and apical aspects of prostate. Today´s standard is at least five cores from each side of the prostate at first biopsy. If first sample is negative there will usually be another urological exam and a first re-biopsy. The study aim to compare these two methods in cancer detection. The investigators' hypothesis is that when using end-fire technique at first re-biopsy, investigators find more cancers compared to side-fire. Patients are prospectively randomized into two groups, both assessing 12 core biopsies according to study protocol. Primary endpoint is cancer detection. Data will be collected about patient age, PSA-level, prostate size, digital rectal exam, hypoechogenic zones and length of cancers.
