Introduction

Chemotherapy-induced alopecia (CIA) is a common and emotionally distressing side effect for patients with early-stage breast cancer. Scalp cooling (SC) systems, such as Paxman® and DigniCap®, have been FDA-approved for CIA prevention, but their availability is geographically limited. This study explores the efficacy of manual scalp cooling (using systems like Penguin Cold Cap), in combination with standardized caregiver training, to evaluate its impact on hair preservation and patient experience.

Objective

The study’s objective was to evaluate the efficacy of manual scalp cooling in preventing CIA in patients with early breast cancer, as well as the value of caregiver training in improving outcomes and patient satisfaction.

Methods

A pilot study was conducted with 10 evaluable patients who received curative chemotherapy and used the Penguin Cold Cap system. Caregivers designated to assist with scalp cooling received standardized training. Effectiveness was measured using the Dean’s alopecia scale 30 days after treatment, focusing on hair retention (<50% hair loss, score 0-2). Exit interviews were also conducted to assess patient experience.

Results

• Scalp Cooling Efficacy: 80% of patients (8 out of 10) achieved the primary endpoint of retaining more than 50% of their hair, with Dean’s alopecia scores of 0-2. Only 1 patient reported using head coverings to disguise hair loss. There were two trial failures due to premature treatment discontinuation.
• Scalp Cooling Safety: Of the 16 adverse events reported, only one (6.25%) was possibly related to scalp cooling, consisting of mild head discomfort.

Analysis

• Scalp Cooling Efficacy: Manual scalp cooling was effective in most patients for preventing CIA, with an 80% success rate. Caregiver training was essential to maximize this efficacy, as proper system application was crucial for positive results.
• Scalp Cooling Safety: The system was well tolerated, with very few related adverse effects. This suggests that manual scalp cooling is a safe option for most patients.
• Study Heterogeneity: While the study showed promising results, the small patient sample and lack of a control group limit the generalizability of the findings. Larger controlled studies are needed to confirm these findings.
• Quality of Life and Psychological Outcomes: Patient-reported evaluations showed improvements in emotional function and future outlook after treatment. Most participants felt that scalp cooling improved their quality of life by allowing them to maintain a more «normal» appearance, which reduced the emotional impact of treatment.

Key Data Points

• Alopecia Risk Reduction: 80% of patients retained more than 50% of their hair.
• Relative Risk (RR): No RR was specified in this study.
• Number of Participants: 10 evaluable patients.
• Chemotherapy Type: Regimens including ACT/HP, TCH/P, TC, and TH.
• Adverse Events: Only one mild adverse event related to scalp cooling was reported (mild headache).

Conclusion

The study concludes that manual scalp cooling is an effective and safe option for preventing chemotherapy-induced alopecia in patients with early breast cancer. Standardized caregiver training is crucial to maximize treatment efficacy. Although the results are promising, more research is needed to validate these findings and to develop clinical tools that help patients make informed decisions about using scalp cooling.
