Clinical Trials: 80% save their hair with Penguin Cold Caps
Published: November 30, 2021
80% of patients saved their hair in a recent clinical trial using Penguin Cold Caps manual system, compared to 50% and 66% in prospective trials with machine-based scalp cooling devices, such as Paxman and Dignicap.
“90% of patients said
it was worth it”
The findings of a recent two-year pilot trial performed at Providence Portland Medical Center. with patients diagnosed with early-stage breast cancer, have now been published. The trial monitored patients’ experience and reported the efficacy of using Penguin Cold Caps while undergoing chemotherapy treatment.
Chemotherapy-induced alopecia (CIA) is a distressing side-effect of the treatment for breast cancer. The study cited that practitioners in some localities have been slow to adopt scalp cooling (or cold capping). As well as the efficacy of the therapy itself. This study sought to address the practicalities of cold cap training in the real-world setting and assist clinicians on how best to identify patients who would benefit from manual scalp cooling.
All patients were
- over 18 years old,
- had no pre-existing scalp condition
- about to undergo a course of chemotherapy for early-stage breast cancer
- had a friend or family member, or a Penguin trained capper
The Penguin Cold Caps were fitted and changed every 20-30 minutes. Cold capping began 50 minutes before the chemo infusion and continued for 4-hours following completion.
80% of patients saved more than 50% of their hair – which was the primary efficacy endpoint. However, most patients anecdotally saved more than 50%, with only one requiring the use of a headcover to conceal any hair loss. 20% of patients discontinued prematurely, and overall hair loss was not recorded.
Was it worth it?
90% of patients said it was worth it when asked. 100% saying they would recommend it to others. 80% saying they would undertake scalp cooling again.
Only 4.17% were upset by the amount of hair loss
87.5% said participation was an overall positive experience. The same number (87.5%) speculated that their quality of life would have decreased if they had lost their hair. They also cited a potential negative impact on their careers, privacy, self-esteem, and self-image if they had not kept their hair.
“Hair preservation impacted an
improvement in self-confidence”
It’s accepted that cold capping can be time-consuming and repetitive process. Patients universally agreed that training is of the utmost importance. The majority consider, efficacy dependent on the training received by the hands-on support of a caretaker (friend or family member) or the professional services of a qualified capper.
