Study on the Effectiveness of an Emollient Cream Containing Pre and Postbiotic and Niacinamide 4% in the Treatment of Skin Xerosis and Itching in Oncological Patients Treated With Anti-EGFR.

Full description

Epidermal growth factor receptor inhibitors (EGFRi) are drugs approved as treatment options in several solid tumors, such as advanced colon, head-neck, breast and lung cancers, because overexpression or mutation of EGFR is implicated in the pathogenesis of these types of cancer. EGFR, in addition to being expressed by neoplastic cells, is also present constitutively on basal keratinocytes, and its inhibition can determine in these cells apoptotic effects, cell growth inhibition, alteration of physiological cell migration and inflammatory processes through the release of pro-inflammatory cytokines, recruitment of leukocytes and the release of pro-apoptotic molecules.

Among the possible adverse skin events (cae), the papulo-pustular rash is the most frequent in the course of therapy with EGFRi (45-90%). In addition to the papulopustulous rash, xerosis and itching are the main dermatological AE associated with EGFRi therapy, with a significant negative impact on the quality of life (qol) of cancer patients.

The reduction of itching and subsequent scratching can therefore be effective in preventing the exacerbation of skin lesions and improving qol in cancer patients, especially in those who experience intense skin xerosis. Emollients containing urea and ceramides have proved useful in skin hydration in case of cutaneous xerosis and in attenuating the associated itching. However, there are few articles in the literature that compare the moisturizing and antipruritic effects of the various basic components of emollients, especially in patients undergoing oncological treatment with EGFRi.

The goals are to examine the effectiveness of an emollient cream containing the prebiotic α-glucan oligosaccharide, the postbiotic Lactobacillus ferment pure (obtained by patented extraction method BPTech) and niacinamide 4%, in the treatment of xerosis, and to test the effectiveness and superiority of this topical preparation in skin hydration and in soothing pruritic symptoms compared to a 10% urea cream commonly used in clinical practice in patients with skin xerosis.
