216 Background: Chemotherapy-induced peripheral neuropathy (CIPN) features debilitative neuropathic pain and neurologic deficits, commonly present in breast cancer population exposed to certain chemo-agents. Given suboptimal effects often rendered by limited therapeutic options, CIPN is associated to psychological distress and drug-seeking behaviors, which leads to heightened functional impairment and disease burden. Acupuncture has gained clinical recognitions for alleviating pain and mental distress, but its impact on medication uses for pain or psychiatric disorders in CIPN remains unclear. As such, this study aims to investigate the association between acupuncture and use of these medications among breast cancer patients experiencing CIPN. Methods: This survival analysis utilized data from the TriNetX Network comprising real-time electronic health records from over 60 healthcare organizations across the United States. Breast cancer patients over 18 at the index date within 01/01/1997 (inception of acupuncture practice in US) and 05/10/2023, diagnosed with CIPN after exposure to chemo-agents such as taxane, platinum, vinca alkaloids, thalidomide, or bortezomib, were identified as the baseline cohort. Patients who received at least three acupuncture sessions post CIPN diagnosis were compared to those without any acupuncture record. Endpoints included prescription of sedative/hypnotics, anti-depressants, anti-psychotics, anti-convulsant agents, and opioid analgesics, within a twelve-month follow-up period after index date. Antibiotics use was the negative control outcome. A 1:1 propensity-score-matching (PSM) method was applied for between-group balance of demographics, BMI, cancer treatment history, health comorbidities, and concurrent medications, followed by hazard ratios and 95% CI calculation using Cox regression model. Results: Among 398 PSM pairs, acupuncture group demonstrated significantly lower hazards of sedative/hypnotics (HR= 0.74, 95% CI 0.61-0.9), anti-depressants (HR= 0.75, 95% CI 0.61-0.93), anti-psychotics (HR= 0.74, 95% CI 0.58-0.96), anticonvulsants (HR= 0.48, 95% CI 0.27-0.87), and opioids (HR= 0.78, 95% CI 0.65-0.94) use, whereas antibiotics showed insignificant result (HR= 0.75, 95% CI 0.55-1.02). The significance sustained after sensitivity analyses, excluding patients with concurrent other cancers, and narrowing follow-up period down to the last nine months to concentrate on treatment effects. Conclusions: Our study suggests a decreased need of opioids and neuropsychiatric medication associated with acupuncture treatment among breast cancer patients endorsing CIPN. Rigorous clinical studies are warranted to validate the causal underpinnings.
