Abstract
Introduction and objectives

Hemorrhagic cystitis (HC) after pelvic radiotherapy occurs in 2–8% of patients. A variety of treatments have been described, most of them with uncertain results. We assessed the efficacy of hyperbaric oxygen therapy (HBOT) in HC cases.

Patients and methods

Retrospective analysis of patients with HC after pelvic radiotherapy receiving HBOT at our center between January 2002 and January 2010. Our protocol included 40 sessions of HBOT in a multiplace hyperbaric chamber with 90minutes of 100% oxygen breathing at 2.2 atm. Success was evaluated in terms of total or partial stop of bladder bleeding. Telephone follow-up was updated at the time of submission in all cases.

Results

Twenty-five patients were treated (21 male, 4 female); the mean age was 66.7 years. Twenty men were irradiated for prostate cancer and one for bladder cancer. Three women had cervix cancer and one endometrial cancer. In all cases previous conservative treatment had failed and HBOT was considered only after other measures failed. All the patients responded to HBOT and none recurred after end of treatment at a mean followup of 21.2 months. There were no serious complications.

Conclusion

HBOT is a highly effective and safe, non-invasive therapy for HC secondary to pelvic radiation; it should be considered as a first-line alternative in these difficult cases.

Resumen
Introducción y objetivo

La cistitis actínica (AHC) secundaria a la radioterapia pélvica ocurre en 2–8% de los pacientes. Se han descrito múltiples tratamientos con resultados variables, habitualmente frustrantes. Nuestro objetivo fue evaluar la eficacia de la oxigenoterapia hiperbárica (OHB) como tratamiento de la AHC.

Material y métodos

Análisis retrospectivo de los pacientes con AHC secundaria a radioterapia pélvica que recibieron OHB entre enero de 2002 y enero de 2010. Los pacientes recibieron 40 sesiones de OHB en una cámara hiperbárica multiplaza, respirando 90 minutos de oxígeno al 100% a 2,2 atm. Se evaluó la respuesta con relación al cese total o parcial de la hemorragia.

Resultados

Veinticinco pacientes fueron tratados (21 varones y 4 mujeres), con edad promedio de 66,7 años. Veinte hombres fueron irradiados por cáncer de próstata y uno por cáncer de vejiga. Tres mujeres tenían cáncer de cuello uterino y una cáncer de endometrio. En todos los pacientes habían fracasado los tratamientos conservadores previos y la OHB fue considerada sólo tras fallar otras medidas. Todos los pacientes respondieron al tratamiento con OHB y ninguno ha presentado recidiva después de terminar el tratamiento en un período de seguimiento promedio de 21,2 meses. No hubo complicaciones graves.

Conclusión

La OHB es un tratamiento no-invasivo, altamente eficaz y seguro para el tratamiento de la AHC secundaria a radioterapia pélvica, por lo que debe considerarse como alternativa de primera elección en estos complejos casos.
