BACKGROUND: The purpose of this study was to evaluate the ability of rectal suppository of hyaluronic acid to limit symptoms of acute radiation proctitis in patients with prostate cancer (PC).
MATERIALS AND METHODS: From January 2011 to October 2011, 50 consecutive patients, undergoing radiotherapy with radical or adjuvant intent for PC, were invited to use rectal suppository of hyaluronic acid (HA: Cicatridina® suppository, Farma-Derma s.r.l., Sala Bolognese, BO, Italy) daily, before radiation delivering. An historical group was used as an external control. Acute rectal toxicity was scored weekly according to RTOG criteria. Time to occurrence of acute rectal toxicity was taken as endpoint.
RESULTS: Compliance was good. Only 2% of HA treated patients had a G2 acute proctitis versus 7% of historical group, globally a difference was observed in rate of acute proctitis between the experimental arm and the control group: 32% in experimental arm versus 45% in control group (p = 0.08). A delay in the onset of acute rectal toxicity in patients treated with HA (p = 0.04) was showed.
CONCLUSIONS: Our findings suggested the role of HA in reducing acute proctitis in prostate cancer patients treated with radiotherapy. Further trials are needed to confirm these results.
