Acupuncture for cancer symptoms: Clinical application and longitudinal impact.

Abstract

e23191 Background: Evidence for acupuncture (ACUP) in cancer care is inconsistent. ACUP is variously used for multiple symptoms, e.g. anxiety, chemotherapy-related peripheral neuropathy, dyspnea, hot flashes, insomnia, and pain. Approximately 500 unique patients are treated for ACUP annually in our Section of Integrative Oncology. Our objective was to evaluate ACUP’s clinical application and longitudinal impact on symptoms severity. Methods: This was a retrospective analysis of those treated in a group ACUP session. Symptoms were rated before each session on a severity numeric rating scale (0-10). Clinical improvement was defined as a 2-point decrease from baseline (T1). We report symptoms from baseline to the fourth sessions (T1-T4). Counts are presented as percentages and numbers summarized by mean (standard deviation; SD) or median (interquartile range; IQR). Groups were compared statistically as appropriate. Results: 2239 consecutive patients were treated between 2015-2022. Mean (SD) age was 57 (±12); 83% were female; 57% breast primary site, 9% hematologic, 9% gastrointestinal, 8% gynecologic, 4% lung, 3% prostate, and 9% other malignancies. Symptoms treated were pain (61%), insomnia (48%), fatigue (44%), neuropathy (41%), anxiety (37%), hot flashes (37%), and other symptoms (17%). 68% presented with multiple symptoms. They received a median (IQR) of 4 (2-6) sessions and 7 (7-14) days apart. At T1 symptom severity scores, median (IQR), were anxiety 5(2-7), fatigue 5(3-7), hot flashes 6(4-8), insomnia 6(4-8), neuropathy 5(3-8), and pain 5(3-7); Table1. By T2, improvement was observed in patients, N (%), with hot flashes 476 (66%), anxiety 434 (62%), fatigue 464 (56%), insomnia 407 (55%), neuropathy 441 (55%), and pain 563 (50%). Symptom severity improvement was statistically significant by T2 and by T3 clinically relevant; Table 1. By T4, about 60% were still on ACUP treatment. Multiple ACUP sessions ( > 1) were associated with older age and higher symptom burden, and fewer sessions with more severe T1 anxiety and fatigue. Fewer males were treated, yet symptoms improved like in females. Conclusions: Symptoms were of moderate severity at referral. In this large consecutive sample (N = 2239) of mostly younger breast cancer women, group ACUP was associated with broad based symptom benefit. Repeated ACUP treatments were important for clinical improvement. Males and females benefited equally however fewer males were referred. Several confounders need to be considered interpreting these results. [Table: see text]
