Chemotherapy-induced alopecia causes an important impact on cancer patients and its risk of persistence is currently a considerable issue in cancer survivors. Of the various interventions proposed for the prevention of chemotherapy-induced alopecia, scalp cooling has emerged as an effective and safe strategy. This paper aims to provide an overview on scalp cooling and chemotherapy-induced alopecia prevention.

INTRODUCTION The use of scalp cooling for the prevention of chemotherapy-induced alopecia (CIA) is increasing. Cold caps are placed onto the hair-bearing areas of the scalp for varying time periods before, during, and after cytotoxic chemotherapy cycles. Although not yet reported, improper application procedures could result in undesirable adverse events (AEs). At present, there are no evidence-based scalp cooling protocols, and there is no regulatory oversight of their use. OBJECTIVE To report the occurrence of cold thermal injury (frostbite) on the scalp, following the use of cold caps for the prevention of CIA. MATERIALS AND METHODS We identified four patients who developed cold thermal injuries on the scalp following the application of cold caps. Medical records were analyzed to retrieve the demographic, clinical, and histologic characteristics. RESULTS The cold thermal injuries in our patients were grade 1/2 in severity and improved with topical interventions, although mild persistent alopecia ensued in 3 patients. The true incidence of such injuries in this setting however, remains unknown. CONCLUSIONS Cold thermal cold injuries are likely an infrequent and preventable AE that may result from improper device application procedures during scalp cooling. Although these untoward events are usually mild to moderate in severity, the potential occurrence of long-term sequelae (e.g. permanent alopecia, scarring) are not known. Future prospective studies are needed to further elucidate the risk and standardized delivery methods, and patient/clinical education.

Vemurafenib is a selective inhibitor of V600E-mutant BRAF protein used to treat metastatic and unresectable melanoma. Clinical trials have shown increased overall survival and progression-free survival in patients treated with Vemurafenib. However, cutaneous adverse events are common during treatment. We report fi ve cases of metastatic melanoma with BRAF V600E positivity, treated with Vemurafenib and its cutaneous adverse events. Dermatologists and oncologists need to be aware of possible skin changes caused by this medication, which is increasingly employed in melanoma treatment. Monitoring of patients during therapy is important for early treatment of adverse cutaneous cutaneous adverse events, improvement in quality of life and adherence to treatment.
