Brief summary

Chemotherapy can cause sensory disorders in the hands and feet called peripheral neuropathy. Typical symptoms are pain, loss of sensation, tingling, numbness, and gait disturbances, which worsen patients' quality of life and increase the risk of falls. Little is known about the effect of rosemary oil (applied to hands and feet) on the symptoms of neuropathy. The present study is a feasibility study to see if it is possible to conduct a clinical trial in patients diagnosed with cancer and receiving chemotherapy who report peripheral neuropathy and apply rosemary oil to their hands and feet.

Detailed description

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most common severe dose-limiting side effects that accompany treatment with different chemotherapeutic agents. Patients with CIPN often experience a reduction in quality of life and an increase in fall risk due to symptoms such as pain, sensory loss, paresthesia (tingling, numbness), and gait disturbances. Treatment of CIPN is based on pharmacotherapy, which may in turn cause side effects such as nausea, dizziness, fatigue and others. In addition, various approaches from integrative medicine are used, e.g. acupuncture, touch therapies, mind-body medicine, dietary supplements, and aromatherapy. Little is known about the effect of rosemary oil, applied to hands and feet, on CIPN. The present study is a feasibility study to determine the feasibility of a future clinical trial to investigate the efficacy of topical application of rosemary oil in cancer patients undergoing chemotherapy who develop CIPN.

Design outcomes

Primary

MeasureTime frameDescription
Participation rateWhen participation in the study is offered, before start of chemotherapy and rosemary oil applicationParticipation rate in relation to all eligible patients and the reasons for non-participation. Reasons for refusal to participate in the study will be recorded.

Secondary

MeasureTime frameDescription
Rate of fully completed EORTC QLQ-CIPN20 questionnairesBefore start of chemotherapy and rosemary oil application (baseline), then weekly for 24 weeksThe rate of fully completed EORTC QLQ-CIPN20 questionnaires in relation to incomplete questionnaires and reasons for missing data. EORTC QLQ-CIPN20 is used to measure the severity of CIPN pain and functional symptoms. It includes 20 items in three subscales to evaluate sensory (9 items), autonomic (3 items) and motor (8 items) symptoms and function. Each item is rated on a four-point Likert scale from 1 (not at all) to 4 (very much). Scores are summed up to a total score, which is linearly converted to a scale of 0-100 (a high score means more symptoms and pain).
