The Use of Magnetic Resonance Imaging in the Prostate Cancer Primary Diagnostic Pathway: Is It Ready for Primetime?

Does music from noise-canceling headphones have a beneficial effect on men undergoing transrectal ultrasound-guided prostate biopsy?

Background

The objective of this study was to evaluate the effect of music with noise-canceling headphones on men undergoing transrectal ultrasound–guided prostate biopsy (TRUSPB) in a prospective randomized study.

Methods

From January to February 2020, 94 men underwent TRUSPB at our institution. They were divided into two groups and wore noise-cancelling headphones—group 1 (n = 47) did not listen to music and group 2 (n = 47) listened to music. We examined the patients’ clinical characteristics and compared the objective and subjective measurements before and after the procedures. Primary outcomes included vital signs, the State-Trait Anxiety Inventory (STAI, 20–80) scale; and the visual analog scale (VAS, 0–10) for the assessments of pain, satisfaction, and willingness to repeat the procedure.

Results

There were no significant differences in patients' characteristics or the prebiopsy status between the groups. Postbiopsy vital signs for objective parameters were statistically similar between the groups; however, the subjective parameters were not. Postbiopsy STAI-state and VAS scores were significantly lower and VAS scores for the patients’ satisfaction and willingness to repeat the procedure were significantly higher in Group 2 than in Group 1 (p = 0.004, p = 0.009, p = 0.004, and p = 0.003, respectively). In addition, changes in the STAI-state score before and after the procedure were significant in Group 2 (p = 0.001).

Conclusions

Music from noise-canceling headphones may have beneficial effects on anxiety, pain, satisfaction, and willingness to repeat the procedure in men undergoing TRUSPB.

Role of Multiparametric Magnetic Resonance Imaging in Predicting Pathologic Outcomes in Prostate Cancer

Multiparametric magnetic resonance imaging (mpMRI) and the introduction of standardized protocols for its interpretation have had a significant impact on the field of prostate cancer (PC). Multiple randomized controlled trials have shown that the sensitivity for detection of clinically significant PC is increased when mpMRI results are the basis for indication of a prostate biopsy. The added value with regards to sensitivity has been strongest for patients with persistent suspicion for PC after a prior negative biopsy. Although enhanced sensitivity of mpMRI is convincing, studies that have compared mpMRI with prostatectomy specimens prepared by whole-mount section analysis have shown a significant number of lesions that were not detected by mpMRI. In this context, the importance of an additional systematic biopsy (SB) is still being debated. While SB in combination with targeted biopsies leads to an increased detection rate, most of the tumors detected by SB only are considered clinically insignificant. Currently, multiple risk calculation tools are being developed that include not only clinical parameters but mpMRI results in addition to clinical parameters in order to improve risk stratification for PC, such as the Partin tables. In summary, mpMRI of the prostate has become a standard procedure recommended by multiple important guidelines for the diagnostic work-up of patients with suspicion of PC.
