A Pilot Randomized Controlled Trial Evaluating Essential Oils for Chemotherapy-Induced Peripheral Neuropathy

Area of Science:

• Oncology
• Pain Management
• Complementary and Alternative Medicine

Background:

• Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and debilitating side effect of cancer treatment, affecting up to 60% of patients.
• Current pharmacological treatments for CIPN often yield limited efficacy and can cause adverse effects.
• Essential oils represent an underutilized, non-pharmacological strategy for pain reduction in cancer patients.

Purpose of the Study:

• To evaluate the effectiveness of a topical essential oil intervention in alleviating CIPN symptoms.
• To explore the potential of essential oils as an adjuvant therapy for managing treatment-related pain.

Main Methods:

• A pilot, single-blind, randomized controlled trial involving 27 participants stratified by baseline pain.
• Participants received either a topical essential oil intervention or a placebo for six weeks, applied every eight hours.
• Pain was assessed weekly via the Short-Form-McGill Pain Questionnaire-2, and daily using the Visual Analogue Scale; quality of life was measured using validated questionnaires.

Main Results:

• While no significant overall difference in pain or quality of life was found between groups, both showed improvement.
• A significant reduction in pain was observed in participants using the essential oil intervention concurrently with pain medications compared to placebo (p=0.001).
• Factors such as educational level, annual income, and age were identified as significant covariates influencing pain perception and outcomes.

Conclusions:

• The pilot study confirmed participant adherence to the six-week essential oil intervention.
• Essential oils demonstrate potential for both direct and adjuvant pain-reducing effects in managing CIPN.
• Further investigation into essential oils for pain management in cancer patients is warranted.
