Safety and efficacy of scalp cooling system in preventing chemotherapy induced alopecia - A single center prospective study.

Background: Alopecia is one of the most common and afflicting side effects associated with chemotherapy treatments. Scalp-cooling devices were introduced to reduce hair loss and improve the hair volume recovery in patients undergoing chemotherapy.

Methods: This is a single center, prospective observational study conducted from 01 February 2019 to 31 January 2020, in patients undergoing chemotherapy for various cancers. The extent of alopecia was assessed by two independent clinicians by reviewing the photographs taken at baseline, during each session, and 4 weeks from the last scalp cooling session.

Results: A total of 100 patients (female: 94 and male: 6) were enrolled in the study, with a mean age of 53.5 years. Of 100 patients, 40 received anthracycline based chemotherapy, 45 received taxane based chemotherapy, 9 received both, and 6 received other chemotherapeutic agents. By the end of the study, 31 patients experienced grade 0-1 alopecia and 69 patients had grade 2 alopecia. On multivariate analysis, chemotherapeutic agent was found to be an independent factor for delaying the onset of Grade 2 alopecia (anthracycline vs taxanes (OR: 0.71; 95% CI (0.51-0.92); P ≤ 0.04)The most common adverse events reported during the scalp cooling sessions were chills (7%), and chills with headaches (6%). Scalp metastasis and scalp cooling discontinuation rates were observed to be very rare. No serious adverse events related to device were observed.

Conclusion: Scalp cooling was observed to be more effective in reducing chemotherapy-induced alopecia in patients treated with taxane-based chemotherapy over anthracyclines. Scalp cooling sessions were well tolerated. Scalp metastasis and scalp cooling discontinuation was observed to be very rare.
