Abstract
PURPOSE
The aim was to evaluate the effect of a topical formulation containing chitosan-coated Chamomilla recutita (L.) rauschert microparticles regarding the incidence, grade, and days for the appearance of radiodermatitis (RD) in women with breast cancer.
METHODS
A double-blinded, controlled, randomized, phase II clinical trial developed with women diagnosed with breast cancer who will receive radiation therapy. The participants were randomly divided into 2 groups: control and treatment. They were followed up until the end of the treatment or the appearance of grade III RD.
RESULTS
Fifty-four women were included in the study. There is no significant difference between the groups in the incidence (88.9% vs. 88.9%, P=1.0) or time to develop any grade of RD (3 days of difference, P=0.300). A significant reduction was observed in the incidence (P=0.03) and in the time to appearance (7 d of difference, P=0.01) grade 2 or >RD. In the follow-up evaluation (15 d after the end of treatment), the Chamomile group presented a superior skin recovery than the control group (P=0.0343). High-intensity local symptoms as pain, and pruritus were significantly reduced in the Chamomile group.
CONCLUSIONS
Although no effect was observed with chamomile to reduce any grade of RD, it was effective to reduce grade 2 or >toxicity, to improve skin recovery and to diminish high-intensity local symptoms.
