Continuous Controlled Cooling for Prevention of Chemotherapy-Induced Peripheral Neuropathy (COOL-tax)

29. oktober 2026 opdateret af: Vastra Gotaland Region

Continuous Controlled Cooling for Prevention of Chemotherapy Induced Peripheral Neuropathy: A Randomized Controlled Trial

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of certain types of chemotherapy and can cause numbness, tingling, pain, and other symptoms in the hands and feet. There is currently no established method for preventing CIPN.

The purpose of this randomized controlled trial is to investigate whether continuous, controlled cooling of the hands and feet during chemotherapy can reduce the development and severity of CIPN. Participants will be randomly assigned to receive either cooling with the Hilotherm device during chemotherapy or standard care without cooling.

The study will compare peripheral neuropathy between the two groups and assess whether continuous cooling can help prevent chemotherapy-induced peripheral neuropathy.

Studieoversigt

Detaljeret beskrivelse

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and potentially long-lasting adverse effect of taxane-based chemotherapy. Currently, there is no established preventive treatment for CIPN. Previous studies of cooling interventions have shown promising results, but the available evidence remains limited.

The proposed mechanism of cooling is cold-induced vasoconstriction, which may reduce peripheral exposure to neurotoxic chemotherapy agents. Conventional cryotherapy using frozen gloves and socks has practical limitations, including fluctuating temperatures, frequent replacement, patient discomfort, and increased workload for healthcare personnel. Continuous cooling with hilotherapy provides stable temperature control and may therefore offer a more tolerable and feasible approach.

This study will evaluate whether hilotherapy can reduce chemotherapy-induced peripheral neuropathy in patients with non-metastatic breast cancer receiving taxane-based chemotherapy. The study will also provide information on the feasibility and acceptability of implementing hilotherapy in routine oncology care and explore circulating biomarkers in relation to the development of neuropathy.

Tidsramme
Incidence of Clinically Meaningful Chemotherapy-Induced Peripheral Neuropathy
Tidsramme: From enrollment to 6 months after completion of taxane-based chemotherapy

Clinically meaningful chemotherapy-induced peripheral neuropathy (CIPN) is defined as a ≥10-point increase from baseline in the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy (EORTC QLQ-CIPN20) sensory subscale score. The EORTC QLQ-CIPN20 is a patient-reported questionnaire assessing symptoms and functional impairment related to CIPN. Scores are transformed to a 0-100 scale, with higher scores indicating greater symptom burden.

Incidence of NCI-CTCAE Grade ≥2 Peripheral Neuropathy
Tidsramme: Baseline (before chemotherapy), at initiation of taxane treatment (Week 0), at Weeks 3, 6, and 9 (if applicable), and 6 months after completion of taxane treatment.

Incidence of NCI-CTCAE grade ≥2 peripheral sensory neuropathy, peripheral motor neuropathy, and paresthesia. Neuropathy is assessed by healthcare professionals using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 6.0.

Baseline (before chemotherapy), at initiation of taxane treatment (Week 0), at Weeks 3, 6, and 9 (if applicable), and 6 months after completion of taxane treatment.
Change in EORTC QLQ-CIPN20 Motor and autonomic Subscale Score
Tidsramme: Baseline (before chemotherapy), at initiation of taxane treatment (Week 0), at Weeks 3, 6, and 9 (if applicable), and 6 months after completion of taxane treatment.

Change from baseline in the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20-item module (EORTC QLQ-CIPN20) motor and autonomic subscale scores.

Both subscale scores are transformed to a 0-100 scale (minimum 0, maximum 100). Higher scores indicate greater symptom burden and therefore a worse outcome. Change from baseline reflects the difference between the follow-up and baseline score; accordingly, an increase indicates worsening symptoms, while a decrease indicates improvement.
