Brief summary
Cancer patients undergoing chemotherapy experience various side effects depending on the treatment protocol used. Chemotherapy-Induced Peripheral Neuropathy (CIPN) is a dose-limiting and quality-of-life-reducing complication caused by chemotherapeutic agents. The development of neuropathy not only restricts patients' physical functions but may also lead to dose reduction or even the discontinuation of chemotherapy. Among chemotherapeutic agents, taxanes are among the most common causes of neuropathy. Docetaxel and paclitaxel, which belong to the taxane group, are widely used chemotherapeutics in the treatment of breast cancer. The degeneration, which manifests as numbness, tingling, and burning sensations in the fingers and toes, progresses from the distal to the proximal end of peripheral nerve axons. Although several potential agents have been clinically tested to prevent CIPN, no pharmacological agent other than duloxetine, which has limited efficacy, has been proven effective. A review of the literature reveals that non-pharmacological methods used in the management of peripheral neuropathy include transcutaneous electrical nerve stimulation (TENS), massage, exercise, heat and cold application, relaxation techniques, acupuncture, and reflexology. Studies investigating the effectiveness of local water baths in the treatment of neuropathy have reported that this approach is effective in managing neuropathic symptoms. This randomized controlled trial aims to evaluate the effects of local heat and cold application on neuropathic symptoms in breast cancer patients undergoing chemotherapy. Data will be collected using the Patient Information Form, Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT), and the Heat and Cold Application Patient Follow-up Form. Assessments will be conducted in both the intervention and control groups before the intervention and at the end of a 4-week period. This study is designed as a randomized controlled trial to determine the effects of local heat and cold application on neuropathy in patients with chemotherapy-induced peripheral neuropathy.
Detailed description
Breast cancer patients undergoing chemotherapy experience various side effects depending on the treatment protocol used. The most common side effects include neutropenia, anemia, peripheral neuropathy, nausea, vomiting, diarrhea, constipation, and fatigue. Chemotherapy-Induced Peripheral Neuropathy (CIPN) is a dose-limiting and quality-of-life-reducing complication caused by chemotherapeutic agents. CIPN can develop either during or after chemotherapy and not only restricts patients' physical functions but may also lead to dose reduction or even treatment discontinuation. Among chemotherapeutic agents, taxanes are among the most common causes of neuropathy. Docetaxel and paclitaxel, which belong to the taxane group, are widely used chemotherapeutics in the treatment of breast cancer. The incidence of taxane-induced peripheral neuropathy varies between 61% and 92%. Although taxane-induced neuropathy primarily presents with sensory symptoms, it is a toxicity that can also affect motor and autonomic functions. The degeneration, which manifests as numbness, tingling, and burning sensations in the fingers and toes, progresses from the distal to the proximal end of peripheral nerve axons. Neuropathy in the upper extremities typically appears later. The neurotoxicity of taxane-induced neuropathy is dose-dependent, and progression ceases once the drug treatment is completed. Emerging symptoms can be prevented by reducing the drug dose or increasing the interval between doses. However, these adjustments may significantly compromise cancer treatment outcomes. Although numerous potential agents have been clinically tested to prevent chemotherapy-induced peripheral neuropathy, no pharmacological agent other than duloxetine, which has limited efficacy, has been proven effective. A review of the literature reveals that non-pharmacological methods used in the management of peripheral neuropathy include transcutaneous electrical nerve stimulation (TENS), massage, exercise, heat and cold application, relaxation techniques, acupuncture, and reflexology. Medical baths have been used in the treatment of inflammatory and non-inflammatory rheumatic diseases, fibromyalgia, and chronic back pain, as well as for reducing fatigue and improving sleep regulation. In particular, foot bath studies have reported that foot baths increase blood circulation through vasodilation in peripheral blood vessels, improve sensory symptoms, stimulate the sense of touch, reduce sympathetic nerve activity, enhance skin permeability, promote microcirculation in cells, and support drug therapy. A review of the literature indicates that very few studies have investigated the effects of foot baths on the management of peripheral neuropathy in cancer patients. Studies examining the effectiveness of local water baths in the treatment of neuropathy have reported that this approach is an effective strategy for managing neuropathic symptoms
Interventions
OTHERExperimental- Heat application
Heat application + standard protocol=Hot Application Protocol Hot application will start daily and continue until the completion of 4 weeks. The area will be checked for infection, scar tissue, inflammation, and incision before the application, and the procedure will be explained to the patient and their family. The first application will be performed on the day the patient comes for chemotherapy, ensuring privacy by exposing only the application area and positioning the patient appropriately. Patients will be asked to sit on a chair or couch with both feet immersed in a foot bath containing 5 liters of water, approximately 5 cm above their ankles, every night before bed for one month. The water temperature will be 40°C. The application will last for 30 minutes. Patients will be advised to avoid contact with cold water, as well as the consumption of cold food and beverages.
OTHERExperimental-Cold application
Cold application + standard protocol=Cold application will start daily and continue until the completion of 4 weeks. The area will be checked for infection, scar tissue, inflammation, and incision before the application, and the procedure will be explained to the patient and their family. The first application will be performed on the day the patient comes for chemotherapy, ensuring privacy by exposing only the application area and positioning the patient appropriately. Patients will be asked to sit on a chair or couch with both feet immersed in a foot bath containing 5 liters of water, approximately 5 cm above their ankles, every night before bed for one month. The water temperature will be between 23-26°C. The application will be performed by the researcher on the day the patient comes for weekly chemotherapy treatment. Patients will be advised to avoid contact with hot water, as well as the consumption of hot food and beverages.

Intervention model description
The study population will consist of breast cancer patients receiving taxane-based chemotherapy at the Daytime Chemotherapy Unit of a training and research hospital who meet the inclusion criteria. The sample size calculation was performed for the study. Before conducting the power analysis, the effect size needed to be determined. In this study, the effect size was derived from a similar previous study. Considering a Type I error (α) = 0.05 and Power (1-β) = 0.90, the effect size (d) was selected as 0.35 based on a one-way analysis of variance (ANOVA). Using G\*Power 3.1.9.7, the minimum required sample size was calculated as 108 participants. Based on these parameters, the expected minimum sample size is 36 patients per group, with a total of 108 participants. However, considering potential dropouts during the study, a total of 114 patients are planned to be included.

| Measure | Time frame | Description |
|---|---|---|
| 1. Chemotherapy-Induced Peripheral Neuropathy Assessment Tool (CIPNAT) | At baseline (first visit) and at 4 weeks | The Turkish validity and reliability of the scale were tested in breast cancer patients receiving taxane chemotherapy (n=430). The first section assesses sensory and motor symptoms (numbness, itching, burning, discomfort, cold sensitivity, pain, weakness, balance problems), with responses scored from 0 to 10. Higher scores indicate greater discomfort. In the second section, difficulties in daily activities (e.g., dressing, walking, working, exercising) are also rated from 0 to 10. The scale's overall Cronbach alpha is 0.87, with test-retest reliability ranging from 0.90 to 0.96. These results confirm that the scale is valid and reliable for the Turkish population. |
| Local Heat and Cold Application Patient Follow-up Form | At baseline (first visit) and at 4 weeks | This form is designed to assess patients' adherence to local heat or cold application. During the heat or cold application process, patients will be followed up by phone to enhance their adherence to the program and ensure compliance. In addition, when patients come to receive their weekly chemotherapy doses, the application will be performed by the researcher. Patients will mark their heat or cold application status on the form while performing the application at home. The forms will be reviewed by the researcher when patients visit the hospital for chemotherapy treatment. Patients who perform the application less than four times per week will not be included in the evaluation. |
