The effect of aroma lymphatic tressage on taxane-induced lower-extremity edema in breast cancer patients.

Abstract

Background: Taxanes are effective chemotherapy drugs for breast cancer care, but adverse effects pose a significant challenge in cancer treatment. Taxane-induced fluid retention and lower-extremity edema are two of the important dose-limiting toxicity and result in decreased quality of life (QoL). However, there is no standard of care to alleviate the symptoms. We conducted a clinical study to assess the efficacy of short-term aroma lymphatic tressage therapy (ALTT) in reducing taxane-induced edema in breast cancer patients.

Methods: In this phase 2 clinical trial, patients with edema of CTCAE grade 2 or higher were enrolled and conducted 8 sessions of ALTT. The primary endpoint was to determine the proportion of patients with a reduction in lower extremity circumference of 3% or more before and 6 weeks after starting ALTT. The change in QoL was assessed as the secondary endpoint using QoL questionnaires.

Results: A total of 37 breast cancer patients completed the protocol and were analyzed. The median sum of the 3-point circumference (thigh, calf, and ankle) was 230.8 cm (IQR 218-243) in the baseline and 220.2 cm (IQR 212-236) at the end of the study. The average decrease of circumference was 3.8%. About, 23 patients (62%) experienced a circumference decrease of 3% or more. An improvement in every scale of FACT-TAXANE and EORTC-QLQ-C30 was observed when comparing questionnaire results before and at the end of the intervention (P < 0.0001).

Conclusion: Eight sessions of ALTT over 4 weeks were effective in reducing lower-extremity edema and resulted in improvement of QoL in patients with breast cancer.
