Satisfaction and Quality of Life Comparison Between Patients Using Cicaplast Baume B5 Versus Dexeryl for the Management of Cutaneous Toxicities Induced by Epidermal Growth Factor Receptor Inhibitors (iEGFR)

This randomized comparative study aims to evaluate the satisfaction and quality of life of patients using Cicaplast balm B5, versus Dexeryl, for the management of cutaneous toxicities of iEGFR in squamous cell carcinoma of the head and neck, cancers colorectal or pulmonary

The arrival of new therapeutic strategies such as targeted therapies has led to real progress in the treatment of cancers. Tyrosine kinase inhibitors and antibodies to epidermal growth factor receptors (EGFR), or iEGFR, target one of the major pathways of tumor cell proliferation. These treatments have demonstrated their interest in the treatment of certain advanced solid malignant tumors (head and neck cancer, colorectal cancer, bronchial cancer).

Although having a much better tolerance profile than the "classical" cytotoxic treatments used in the same indications, these treatments, however, have frequent cutaneous toxicities that are inconvenient for patients. According to the molecules, they can affect 80 to 90% of patients treated from the first weeks of treatment and to different degrees. They appear as well in the skin (acneiform rash, erythema, desquamation, xerosis, pruritus) as skin appendages (paronychia, alopecia).

The consequences of these adverse effects are significant, which may be at the origin of a decrease in dose or even of a stop of anti-tumoral treatment inducing a reduction of the expected clinical benefit. In addition, they represent for the patient a real source of inconvenience and pain, which can impact the quality of life (choice of dress, feeling of shame because of the appearance of the skin ...) and impact the adherence to iEGFR treatment.

Management includes first and foremost preventive measures: the use of moisturizing topicals and dermatological soap-free surgras is recommended as soon as iEGFR treatment is initiated, and preventive systemic treatment with cyclins (doxycycline 100 mg daily) is proposed for at least 6 weeks and then reevaluated for skin toxicity.

In case of appearance of skin toxicities, it is initially prescribed in common practice a topical such as Dexeryl (used in many hospitals as standard) or Cicaplast Balm B5 La Roche Posay (used in current practice at Léon Bérard Center). In a second step, topical corticosteroids are prescribed, depending on the grade of toxicity.

There is, however, no validated argument in the literature to guide the choice of clinicians to use either of these topics. Cicaplast balm B5 (antibacterial, repairing damaged skin, moisturizing and relieving feelings of discomfort) would limit the aggravation of skin toxicities and therefore the use of pharmacological measures, including topical corticosteroids class 3 or 4 may long term, weaken the skin barrier even more.
