Positive Effects of HIIT Exercise program on BCR progression of PC

[MateoBeach]

From the ASCO2021 programs. Good randomized trial of supervised intensive exercise for 12 weeks improves risks for BCR progression.

I suspect this may be related to the effects of exercise, and especially HIIT to activate epigenetic pathways for protection of the genome and reducing mutations, a driver of cancer progression.

A phase II randomized controlled trial of exercise on biochemical progression in men with prostate cancer on active surveillance.

Background:

Men with prostate cancer (PCa) undergoing active surveillance (AS) are at increased risks of cardiovascular death and disease progression. Any intervention that can address these issues during AS would be highly beneficial. Clinical and preclinical studies have demonstrated the benefits of exercise to improve cardiovascular health in cancer patients and suggested the potential role of exercise in suppressing PCa progression in men with PCa undergoing AS. Therefore, the purpose of this study was to investigate the effects of exercise on cardiorespiratory fitness and biochemical progress of PCa in men with PCa on AS.

Methods:

The Exercise During Active Surveillance for Prostate Cancer (ERASE) Trial was a single-centre, two-armed, randomized controlled trial in Edmonton, Canada. 52 men with localized PCa who were undergoing AS were randomized to high-intensity interval training (HIIT; n = 26) or usual care (UC; n = 26). The HIIT group performed thrice-weekly, supervised, aerobic HIIT on a treadmill at 85-95% of peak cardiorespiratory fitness (VO2peak) for 12 weeks. The primary outcome was VO2peak, and the secondary and exploratory outcomes included biochemical progression of PCa (prostate-specific antigen [PSA]), PSA kinetics, and growth of prostate cancer cell line LNCaP.

Results:

46/52 participants (88%) completed the postintervention VO2peak assessment and adherence to HIIT was 96%. Compared to UC, HIIT significantly improved VO2peak (adjusted between-group mean difference, 1.6 ml·kg-1·min-1; 95% confidence interval [CI], 0.3 to 2.9; p= 0.014). HIIT also significantly reduced PSA level (adjusted between-group mean difference, -1.1 ug/L; 95% CI, -2.1 to 0.0; p= 0.043) and PSA velocity (p= 0.040), and suppressed LNCaP cell growth (p =0.024). No significant differences were found in PSA doubling time (p= 0.10) and testosterone (p= 0.24).

Conclusions:

The ERASE Trial is the first randomized controlled trial to demonstrate the impact of HIIT exercise for improving physical fitness and inhibiting biochemical progression of PCa in men with localized PCa on AS. Our findings suggest that supervised aerobic HIIT may be a promising intervention in this clinical setting. Larger-scale randomized controlled trials are warranted to determine if improvements in physical fitness and PCa-related markers translate into improved long-term clinical outcomes in these men such as disease progression, receipt of radical treatments, posttreatment complications, and survival.

Great Post!

I guess I won't throw away my HRM and Kettlebells!

The question for this forum is do these benefits translate to us in some way of will the radical treatments negate all the benefits?

NO HIIT 4 ME >>>

just long and slow 😀

[treedown in reply to addicted2cycling]

I wouldn't call you slow in any cycling crowd but that's my thing now as well.

Faster on the FLATS so "Come-On-Down" 😀
