Introduction
This article addresses one of the most distressing side effects of chemotherapy: induced alopecia. Hair loss has a considerable emotional impact, affecting patients’ self-esteem, body image, and social relationships. This study investigates the efficacy of scalp cooling caps as a method to prevent alopecia in patients receiving chemotherapy, a topic that has generated varied results in previous research due to differences in chemotherapy regimens, cooling devices, and other factors.
Objective
To evaluate the effectiveness of scalp cooling caps in preventing chemotherapy-induced alopecia in patients undergoing various treatment regimens, including doxorubicin, docetaxel, and FEC (5-fluorouracil, epirubicin, and cyclophosphamide).
Methods
A prospective study was conducted with 64 female patients. They were administered chemotherapies of doxorubicin, docetaxel, FEC, or a combination of docetaxel followed by FEC. Patients wore gel-based cooling caps, changed every 40-45 minutes during and after chemotherapy infusion. Instructions were provided for hair care at home during the first 1-3 days after each chemotherapy session. Hair loss was evaluated after the third, sixth, and final treatment cycle using modified criteria from the International Common Toxicity Criteria version 3.0.
Results
- Significant hair loss was avoided in 79.7% of patients.
- Results were more favorable in groups receiving doxorubicin (100% avoided significant alopecia) and docetaxel (83.3%), while the group treated with FEC showed a higher incidence of significant hair loss (23.5%).
- In the final evaluation, only 20.3% of patients needed to wear a wig, and 87.5% considered avoiding alopecia important.
Analysis
Scalp cooling caps proved effective in reducing alopecia in most patients, although effectiveness varied by chemotherapy regimen. The best results were obtained in treatments with doxorubicin and docetaxel, while patients with FEC regimens had higher rates of significant hair loss. Practical factors, such as avoiding heat exposure and scalp manipulation after chemotherapy, appear to influence cooling efficacy.
Efficacy of Scalp Cooling
The study confirmed that cooling caps can be effective, successfully preventing significant hair loss in 79.7% of patients. The best results were observed in treatments with doxorubicin and docetaxel.
Safety of Scalp Cooling
Reported side effects were mild in most cases. Some patients experienced discomfort such as headaches or cold sensation on the scalp, although a small percentage (12.5%) reported that cap use was unpleasant but continued its use. No increase in the incidence of scalp metastases was reported.
Study Heterogeneity
The study acknowledges the difficulty in comparing results due to variations in chemotherapy regimens, cooling methods, and other factors such as cap type and evaluation criteria. Despite these differences, results were consistent in showing some degree of protection against alopecia.
Quality of Life and Psychological Outcomes:
Avoiding alopecia was viewed as important for most patients (87.5%), positively influencing their self-esteem and personal relationships, especially in middle-aged women, who highly valued their hair as an important part of their appearance.
Key Data
- Alopecia Risk Reduction: In 79.7% of patients, scalp cooling helped avoid significant alopecia.
- Relative Risk (RR): Not specifically provided, but results suggest significant benefit with cooling use.
- Number of Participants: 64 female patients.
- Chemotherapy Type: Doxorubicin, docetaxel, FEC, and combination of docetaxel followed by FEC.
- Adverse Events: 12.5% of patients found cap use unpleasant, although they continued treatment. A small percentage (6.2%) dropped out of the study due to adverse effects such as headache or intense cold sensation.
Conclusion
Scalp cooling caps are a moderately effective and well-tolerated option for preventing chemotherapy-induced alopecia, especially in treatments with doxorubicin and docetaxel. Despite heterogeneity in results among different studies, the benefits observed in this study support the use of this intervention as a viable option to improve quality of life for patients undergoing chemotherapy.
