electroacupuncture on treating cancer-related depression

Conditions: Depression; Cancer

Summary: cancer-related depression (crd) is a common psychological condition among cancer patients during diagnosis, treatment, and recovery, and is associated with reduced quality of life, impaired immune function, and poorer clinical outcomes. as cancer incidence and mortality continue to rise in china, the psychological burden on patients is receiving increasing attention. electroacupuncture (ea) has shown potential in treating various types of depression and related somatic symptoms, but evidence regarding its efficacy, safety, and long-term effects in crd remains limited. this randomized controlled trial aims to evaluate the short- and long-term efficacy and safety of ea for crd, with the goal of providing evidence to support effective and optimized treatment strategies.

cancer-related depression (crd) is a prevalent and complex comorbidity among cancer patients, often arising during diagnosis, treatment, or disease progression. it is associated with a range of psychological and somatic symptoms that significantly reduce quality of life, compromise treatment adherence, and may negatively affect clinical outcomes and overall survival. as cancer incidence and mortality continue to rise in china's aging population, addressing the emotional and psychological burden of cancer has become increasingly important. current treatments for crd largely rely on pharmacological interventions, particularly selective serotonin reuptake inhibitors (ssris). however, these medications often have delayed onset, potential side effects, and limited tolerability in patients undergoing cancer treatment. these limitations highlight the need for safe, non-pharmacological alternatives that can effectively alleviate depressive symptoms in this vulnerable population. acupuncture, a traditional chinese medical therapy, has been widely used for managing depressive disorders and cancer-related symptoms. electroacupuncture (ea), which combines needling with electrical stimulation, has demonstrated therapeutic potential in preliminary studies for depression and symptom relief in cancer patients. despite encouraging results, the overall quality of evidence remains low, and rigorous randomized controlled trials (rcts) focusing specifically on crd are still lacking. this study aims to evaluate the efficacy and safety of electroacupuncture in the treatment of crd through a well-designed, randomized, assessor-blinded controlled trial. the trial will assess both short-term and long-term outcomes in patients with clinically diagnosed crd, using validated measures for depression severity, quality of life, and symptom burden. participants will be randomly assigned to either an intervention or control group, and all participants will continue to receive routine care during the study. the results of this trial will contribute to the growing body of evidence on integrative approaches in cancer care. it aims to determine whether ea can serve as a safe and effective adjunct to conventional cancer treatment, improve patients' emotional well-being, and support a more holistic model of care. this research also aligns with national health strategies promoting integrative medicine and may inform future clinical guidelines for managing psychological distress in cancer populations.
