What this trial studies

This randomized trial assigns adult cancer patients receiving moderate- to high-emetogenic outpatient chemotherapy to inhale peppermint, lavender, ginger, or placebo (jojoba) using a personal inhalation device during infusions and for four days afterward. Patients inhale the assigned oil hourly during infusion and at least three times daily for four days, and complete questionnaires on nausea, anxiety, and satisfaction. Primary objectives are to determine feasibility of offering aromatherapy in the infusion clinic and patient satisfaction; secondary objectives compare changes in nausea and anxiety versus placebo. The trial enrolls English-speaking adults with ECOG ≤2 who reported nausea >3/10 on their last infusion and have at least two remaining infusion appointments.

Who should consider this trial

Good fit: Adults (≥18) with hematologic or solid tumors receiving moderate- to high-emetogenic outpatient chemotherapy, ECOG ≤2, English-speaking, who experienced nausea >3/10 on their last infusion and have at least two remaining infusion appointments.

Not a fit: Patients with known aversion or sensitivity to lavender, peppermint, ginger, or jojoba oils, those not on moderate- to high-emetogenic regimens, or those with poor performance status are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If effective, aromatherapy could offer a low-risk, drug-free way to reduce nausea and anxiety during and after chemotherapy infusions.

How similar studies have performed: Previous small studies have shown mixed results, with some evidence that ginger and peppermint reduce chemotherapy-related nausea and lavender may reduce anxiety.
