Hand-foot syndrome and nail disorders secondary to treatment with paclitaxel: Is there a relationship with the presence of fungi?

Abstract

Introduction This study aimed to evaluate the frequency of nail disorders and the presence of fungi on the nails of the hands and feet of patients with hand-foot syndrome secondary to treatment with paclitaxel. Methods Prospective study, carried out from October 2018 to December 2019, which included 81 patients undergoing treatment for breast cancer using paclitaxel and had signs and or symptoms of hand-foot syndrome with or without nail disorders. The data were collected through interviews guided by a structured questionnaire, information from medical records and reports of mycological exams. Results The average age of women was 54.7 ± 7.4 years. Nail disorders occurred in 69 patients (85.2%), and of these, 43 (62.3%) were positive for fungi. The fungi were yeasts ( n = 38; 69%), dermatophytes ( n = 15; 27.2%) and non-dermatophyte filamentous fungi ( n = 8; 14.5%). Conclusions Nail disorders were the most frequent manifestations in patients with hand-foot syndrome treated with paclitaxel and occurred in 85.2% of them. It was evidenced that fungi are present on the nails of these patients and can occur in up to 65.28%. The most prevalent fungi were Candida and Trichophyton. The nail lesion was associated with the type of treatment protocol used by the patient. The results of the study point to the need to select safe management alternatives for patients, so they can prevent nail lesions and prevent the proliferation of fungi, consequently reducing negative life impact during treatment.
