Descrição detalhada
Chemotherapy-induced peripheral neuropathy (CIPN) decreases the quality of life of patients and can lead to a decrease and/or interruption of the chemotherapy treatment-limiting its effectiveness. The therapeutic measures for the CIPN are very limited in their number and efficacy.
Main Objectives: 1) To evaluate the clinical effect on the health-related quality of life (HRQOL) of adding ozone to the usual patient´s treatment with persistent pain because of CIPN. 2) Estimate the additional costs and evaluate the cost-effectiveness ratio.
Secondary Objectives: To evaluate the evolution of 3) oxidative stress and chronic inflammation through biochemical measurements; 4) anxiety and depression of patients; 5) the diagnostic and predictive value of hyperspectral imaging in the assessment of pain; 6) the acceptability of patients to a shared decision-making (SDM) tool.
METHODOLOGY: Randomized controlled trial (RCT) phase II-III, randomized, triple-blind; 42 patients with any kind of cancer treated with any kind of chemotherapy, with CIPN of grade > = 2 for > = 3 months.
TREATMENT: All patients will receive: usual treatment + 40 rectal insufflation sessions of O3/O2 in 16 weeks:
- Ozone-Arm (n = 21): concentration of O3/O2 increasing from 10 to 30 μg/ml.
- Control-placebo- Arm (n = 21): concentration of O3/O2 = 0 μg/ml.
Main Variables: At the end of treatment with O3/O2 the following variables will be analyzed: 1) "average pain" secondary to CIPN following the Brief Pain Inventory-Short Form (BPI-SF); 2) health-related quality of life (HRQOL) and utilities using EQ-5D-5L and SF-36 quality of life questionnaires; 3) Direct costs.
Secondary Variables: 3) biochemical parameters of oxidative stress and inflammation; 4) Hamilton scale for anxiety and depression; 5) hyperspectral images; 6) acceptability of patients to a shared decision-making (SDM) tool.
Assessments at weeks: 0 (baseline), 16 (end of O3/O2 insufflations, objective), and 28 (end of follow-up, control).
Length of treatment: 16 weeks.
Follow-up: 12 weeks after finishing O3/O2 insufflation.
Planned length of the clinical trial: 36 months.
