Association between sleep-disordered breathing and prostate cancer.

Area of Science:

• Urology
• Sleep Medicine
• Oncology

Background:

• Sleep-disordered breathing (SDB) is linked to aggressive melanoma.
• The association between SDB severity and other cancers, like prostate cancer (PC), remains unclear.

Purpose of the Study:

• To investigate the relationship between SDB severity and prostate cancer aggressiveness.
• To determine if SDB influences PC tumor stage, Gleason score, or metastasis.

Main Methods:

• 165 prostate cancer patients underwent home respiratory polygraphy to assess SDB using the apnea-hypopnea index (AHI) and oximetric parameters.
• PC aggressiveness was evaluated using Gleason score, tumor stage, and presence of metastasis.

Main Results:

• A high prevalence of SDB was observed in PC patients (AHI≥5 in 78.2%, AHI≥15 in 46.7%).
• No significant differences in median AHI or SDB prevalence were found between patients with varying Gleason scores, tumor stages, or metastatic status.
• Oximetric variables also showed no association with PC aggressiveness.

Conclusions:

• The study did not find evidence to support an association between SDB severity and prostate cancer aggressiveness.
• Despite the high prevalence of SDB in this cohort, it does not appear to be a determining factor in PC aggressiveness.
