Introduction
Chemotherapy-induced alopecia (CIA) is one of the most common and distressing side effects of breast cancer treatment. Hair loss, although temporary, can negatively affect patients’ self-image and emotional well-being. This study addresses the efficacy of scalp cooling (SC) in reducing CIA in early breast cancer patients receiving modern chemotherapy regimens.
Objective
The study's objective was to determine the efficacy of scalp cooling in early breast cancer patients receiving modern chemotherapy, in order to inform future patients about the decision to use or not use this method. Additionally, the impact of hair loss on mood and body image was explored.
Methods
The study was a prospective cohort trial that included 60 patients with stage I to III breast cancer, who were recommended to receive taxane-based or anthracycline-taxane chemotherapy regimens. Patients were randomized to receive scalp cooling at two different temperatures (3°C and 5°C) using the DigniCap system. The primary objective was to evaluate the proportion of patients who experienced minimal hair loss, defined as grades 1 or 2 on the Dean scale.
Results
- Scalp Cooling Efficacy: 33% of patients reported minimal hair loss, not achieving the study's primary objective. The highest success rate was observed in patients who received taxane-only chemotherapy (45%), while those who received anthracyclines and taxanes combined showed the lowest efficacy (20%).
- Scalp Cooling Safety: Scalp cooling-related adverse events were low-grade and resolved without serious complications. The most common side effects included mild scalp pain, headache, and dizziness.
Analysis
- Scalp Cooling Efficacy: Although scalp cooling showed some effectiveness, especially in taxane-based treatments, the primary objective of minimal hair loss was not achieved in the general population. Efficacy varied significantly according to the type of chemotherapy received, with lower results in anthracycline-taxane regimens.
- Scalp Cooling Safety: Scalp cooling was well tolerated, with mild and transient adverse events. Adherence to device use was higher in patients treated with taxanes only.
- Study Heterogeneity: No significant difference was observed in efficacy based on cooling temperature (3°C vs 5°C). The variability in results suggests that other factors, such as patient subjective perception, may influence the evaluation of cooling efficacy.
- Quality of Life and Psychological Outcomes: Although there was a significant improvement in anxiety levels in patients with minimal hair loss, no significant differences were observed in depression or body image. This suggests that hair loss is only one of many factors affecting emotional well-being during chemotherapy.
Key Data
- Alopecia Risk Reduction: 33% of patients experienced minimal hair loss in the general population; this percentage increased to 40% in those who completed the entire scalp cooling treatment.
- Relative Risk (RR): The study does not specify an exact RR, but other studies mentioned in the discussion report an RR of 0.38 in the reduction of chemotherapy-induced alopecia.
- Number of Participants: 60 patients.
- Type of Chemotherapy: Taxane-based regimens and anthracycline-taxane combinations.
- Adverse Events: Included mild scalp pain, headache, dizziness, and skin rashes, all low-grade and resolving within a few days.
Conclusion
The study confirms that scalp cooling can be effective in reducing chemotherapy-induced alopecia in patients receiving taxane-based regimens, with a recommendation for routine use in these cases. For patients receiving combined anthracycline-taxane regimens, an individualized approach is suggested, considering the low efficacy and additional time required for treatment.
