Hyperbaric chambers and local ozonetherapy are procedures to treat ischemic
wounds and delayed scarring in cancer patients. Wounds in irradiated areas
heal slowly and, sometimes, surgical wounds can delay the beginning of the
chemotherapy and/or radiotherapy. We show our experience treating these
wounds with ozone therapy. From 1990 to 1999 our hospitals have treated 28
patients with delayed scarring, 12 in previously irradiated areas. Surgery
has been carried out without success in 7 occasions. Male: Female 10 : 18.
Age: 55 ± 14 (21 - 94). Scars were 56 ± 48 (12 - 182) days old. Areas were
43 ± 79 (0.6 - 293) cm2. Fourteen scars were in breast cancer patients. The
O3/O2 gas mixture was generated from medical oxygen at concentration of 20 -
70 ug/mL.. ozone therapy was carried out by local techniques (bags,
catheters), 23 - 30 minutes 1 - 3 times/week. During ozone therapy, two
wounds received radiotherapy and 7 chemotherapy. Data are showed as: Mean ±
standard deviation (minimum-maximum). Scars were healed in 27 ± 11 (4 - 150)
days, with 7 ± 3 (2 - 22) ozone therapy sessions. In eleven patients
programmed surgery was avoided. Local ozone therapy is an useful treatment:
to: A) accelerate healing wounds in previously irradiated areas B) avoid
delays to start chemotherapy and/or radiotherapy in patients with delayed
scarring after oncologic surgery.
