Introduction:
Literature encloses numerous systematic reviews (SRs) on nonpharmacologic interventions for improving cancer-related fatigue (CRF). The effect of these interventions remains controversial, and the available SRs have not been synthesized yet. We conducted a systematic synthesis of SRs and meta-analysis to determine the effect of nonpharmacologic interventions on CRF in adults.
Material And Methods:
We systematically searched 4 databases. The effect sizes (standard mean difference) were quantitatively pooled using a random-effects model. Chi-squared (Q) and I-square statistics (I²) tested the heterogeneity.
Results:
We selected 28 SRs, including 35 eligible meta-analyses. The pooled effect size (standard mean difference, 95% CI) was -0.67 (-1.16, -0.18). The subgroup analysis by types of interventions showed a significant effect in all the investigated approaches (complementary integrative medicine, physical exercise, self-management/e-health interventions).
Conclusions:
There is evidence that nonpharmacologic interventions are associated with CRF reduction. Future research should focus on testing these interventions on specific population clusters and trajectories.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
