Introduction
Chemotherapy-induced alopecia (CIA) is one of the most common and distressing side effects of breast cancer treatment. Hair loss, though temporary, can negatively impact patients’ self-image and emotional well-being. This study examines the efficacy of scalp cooling (SC) in reducing CIA in early breast cancer patients receiving modern chemotherapy regimens.
Objective
The study aimed to determine the efficacy of scalp cooling in early breast cancer patients receiving modern chemotherapy, to help future patients make informed decisions about using this method. Additionally, the impact of hair loss on mood and body image was explored.
Methods
This prospective cohort study included 60 breast cancer patients in stages I to III, who were recommended to receive taxane 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 assess the proportion of patients experiencing minimal hair loss, defined as grades 1 or 2 on the Dean scale.
Results
-
- Efficacy of Scalp Cooling: 33% of patients reported minimal hair loss, not meeting the study’s primary objective. The highest success rate was observed in patients receiving taxane-only chemotherapy (45%), while those receiving combined anthracycline and taxane regimens showed the lowest efficacy (20%).
-
- Safety of Scalp Cooling: Adverse events related to scalp cooling were mild and resolved without serious complications. The most common side effects included mild scalp pain, headache, and dizziness.
Analysis
-
- Efficacy of Scalp Cooling: Although scalp cooling showed some effectiveness, especially in taxane-based treatments, the primary objective of minimal hair loss was not met in the general population. Efficacy varied significantly depending on the type of chemotherapy received, with lower results in anthracycline-taxane regimens.
-
- Safety of Scalp Cooling: Scalp cooling was well tolerated, with mild and transient adverse events. Adherence to the device was higher among patients treated with taxanes only.
-
- Study Heterogeneity: No significant difference in efficacy was observed between cooling temperatures (3 °C vs. 5 °C). The variability in results suggests that other factors, such as patients’ subjective perceptions, may influence the assessment of cooling efficacy.
-
- Quality of Life and Psychological Outcomes: While 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 just one of many factors affecting emotional well-being during chemotherapy.
Key Findings
-
- Reduction of Alopecia Risk: 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 for reducing 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 of which resolved 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.
