To evaluate the efficacy of HBO on patients who were irradiated because of pelvic organ malignancies, and developed haemorrhagic radiation cystitis.
Material and Methods
We reviewed retrospectively 14 patients from 2001 -2007 with different pelvic organ malignancies, who developed radiation cystitis after irradiation. Patient groups were divided into 2 groups, group 1 (treatment group, n = 10), and group 2 (control group, n = 4). Before therapy chest X ray was done, every patient was examined by E.N.T and internal medicine specialist. 14 patients were entered into our study, and 10 patients were treated for at least 1 month with hyperbaric oxygen. In group 1, mean age was 79 (range: 59–90). 7/10 (70%) males had prostate cancer, every patient received 70 Gy. 3/10 (30%) females, one had colon cancer (50 Gy), one had cancer of Vulvae (50 Gy), one had cervical cancer (56 Gy). In group 2 mean age was 63 years (range: 51–79 years), 3/4 (75%) males had prostate cancer; 1/4 (25%) female had uterus cancer (30 Gy). In group 1 follow up was 1–6 years, mean follow up was 18 months.
In group 1, 2/10 (20%) patients haemorrhage stopped, 3/10 (30%) patients were operated (transurethral coagulation, embolisation of the internal iliac artery), 5/10 (50%) patients needed repeatedly erythrocyte concentrates and urinary catheters. In group 2, 2/4 (50%) patients bleeding stopped spontaneously, 1/4 (25%) patient was operated (transurethral coagulation), 1/4 (25%) patient developed in 5 years additionally cancer of urinary bladder.
Our study showed that treatment of haemorrhagic radiation cystitis with hyperbaric oxygen was not effective in the majority of patients.
