RESUMO
INTRODUCTION: Traditional therapies used to treat chronic wounds are often expensive and, in general, are not adequate to support healing. A promising alternative to conventional dressings is the autologous biopolymer FM, full of cytokines and growth factors that accelerate the healing process of wounds of various etiologies. MATERIALS AND METHODS: The authors report 3 cases in which FM was used to treat chronic oncological wounds that had been conventionally treated for more than 6 months with no sign of healing. RESULTS: Among the 3 reported cases, there was complete healing of 2 wounds. The other lesion did not heal, mainly due to the location (at the base of the skull). However, it significantly reduced its area, extension, and depth. No adverse effects or hypertrophic scar formation were recorded, and the patients reported an absence of pain from the second week of FM application. CONCLUSIONS: The proposed FM dressing approach was effective in healing and speeding up tissue regeneration. It can also be considered one of the most versatile delivery systems to the wound bed, as it is an excellent carrier of growth factors and leukocytes.
