A descriptive and longitudinal cases and controls investigation, of 75 patients with cancer in different locations, admitted to "Conrado Benítez García" Teaching Provincial Cancer Hospital in Santiago de Cuba, in one year, was carried out to evaluate the effectiveness of the CM-95 solution magnetically treated in the prevention and treatment of radiodermitis, applied before and after the radiotherapy by means of topical and oral dose of 15 mL in the 24 members of the study group, as long as, in the control group (27 patients) the same solution was applied without magnetizing; the rest conformed a group (also control group) that didn't receive any of the solutions. In many of the cases the radiodermitis didn't appear and it was not necessary to interrupt the radiotherapy or its suspension time diminished in 7 days, while in the controls the clinical entity was more presented and the clinical course time to renew the radiations was of 15 and 23 days. Most of the patients of the study group improved the adverse effects of radiotherapy, as gastritis, rectitis, diarrheas, lack of appetite, acute distress, and they maintained the hematological parameters in the normal limits.

Background and Objectives. Radiotherapy is usually associated with skin complications that affect the quality of life of patients and in some cases can also affect the timing of the reconstruction. The plateletrich plasma (PRP) is an emerging therapy; is autologous, safe and economic. Current use of PRP includes: efficacy in decreasing local inflammation, enhance wound healing, treatment of skin ulcers caused by radiotherapy and its use extends to the field of aesthetic plastic surgery improving the quality of the skin.The authors made an experimental trial to analyze the use of PRP as a prophylaxis method for skin damage after radiotherapy. We analyze the benefits of PRP as a prophylaxis method for skin damage after radiotherapy using an experimental model. Methods.We conduct a double blind trial with rats. Twelve Wistar rats were used, 2 for obtaining the PRP and 10 for clinical and histological analysis. Results. Data collected from the clinical analysis showed that those areas without PRP: 8 rats presented alopecia and 7 hypopigmentation. Total alopecia was present in 60%, partial alopecia in 20%, and 20% did not present alopecia. In those areas with PRP before radiotherapy: 4 presented alopecia and 3 hypopigmentation. There were no cases of total alopecia, 60% did not present alopecia and 40% presented partial alopecia. Data collected from the histological analysis showed 100% of mild-moderate atrophy in those areas with PRP. On the other hand, 80% of moderate-severe atrophy and 20% of mildmoderate atrophy was present on those areas without PRP. Conclusions. The authors showed the benefit of PRP as a prophylaxis method for alopecia (p<0.05) and hypopigmentation (p<0,1) produced after radiotherapy in this experimental model. [ABSTRACT FROM AUTHOR]
