Major healing of refractory mandible osteoradionecrosis after treatment combining pentoxifylline and tocopherol: a phase II trial

Published on Tuesday, 02 July 2019


BACKGROUND: Osteoradionecrosis (ORN) is a nonhealing wound of the bone that is difficult to manage. Is a treatment combining pentoxifylline (PTX) and tocopherol (vitamin E) boosted by clodronate effective in reversing this fibronecrotic process?

METHODS: Eighteen consecutive patients previously irradiated for head and neck cancer had exteriorized mandible ORN. Length of exposed bone (L) was 13.4 +/- 8 mm, and the mean subjective objective medical management and analytic evaluation of injury (SOMA) score was 12.6 +/- 4.9. Between June 1995 and January 2002, all 18 were given a daily oral combination of 800 mg of PTX and 1000 IU of vitamin E for 6 to 24 months. In addition, the last eight patients who were the worst cases were given 1600 mg/day clodronate 5 days a week.

RESULTS: The treatment was well tolerated. All patients improved at 6 months, with 84% mean L and 67% mean SOMA score reductions. Sixteen (89%) of 18 patients achieved complete recovery, 14 in 5 +/- 2.6 months. The remaining two patients exhibited a 75% response at 6 months.

CONCLUSION: PTX-vitamin E boosted by clodronate is an effective treatment of mandibular ORN that induces mucosal and bone healing in a median period of 6 months.
