Essential of Immediate Exercises on Cancer-Related Fatigue in Patients with Prostate Cancer Receiving Androgen Deprivation Therapy: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: Androgen deprivation therapy (ADT) can cause several adverse effects, including cancer-related fatigue (CRF). CRF has multiple manifestations, with no definitive treatment to date. Among management, exercise has been a field with high complexity and uncertainty. In other words, it has much potential to be explored. To evaluate whether exercise reduces cancer-related fatigue (CRF) in patients receiving androgen deprivation therapy (ADT).

DATA SOURCES: Randomized controlled trials were included and searches were performed from PubMed, Embase, and Cochrane Library databases. We extracted and pooled the CRF, quality of life (QoL), muscle strength, and adverse event severity. The study is registered with PROSPERO (number: CRD 42020203165). Eightteen RCTs were included. The CRF in the exercise group (SMD: -0.18, 95% CI: -0.31 to -0.05) was significantly lower than in the usual care group. The CRF subgroup analysis showed a significant reduction in the immediate exercise group (SMD: -0.37, 95% CI: -0.61 to -0.13), and the combined exercise group (aerobic plus resistance)(SMD: -0.18, 95% CI: -0.36 to -0.01). QoL improvement was also known in the exercise group (SMD: 0.16, 95% CI: 0.01 to 0.32). Leg press and chess press increase ability in the exercise group (SMD: 0.5, 95% CI: 0.42 to 1.05; SMD: 0.42, 95% CI: 0.17 to 0.67, respectively). The enhanced ability of leg press and chess press can also help patients deal with the feeling of CRF.

CONCLUSION: Exercises improve CRF, QoL, and muscle strength in patients receiving ADT.

IMPLICATIONS FOR NURSING PRACTICE:  We suggest immediate combined exercise intervention as supportive therapy to relieve cancer-related fatigue and enhance QoL.
