title: [Radiation proctocolitis following gynecologic radiotherapy: an endoscopic study].
abstract: The prevalence of radiation injuries was assessed in 155 of 206 surviving patients who had had radiation therapy for carcinoma of the uterus or vagina. The patients were examined according to a standardized protocol. 51 (32.9%) exhibited endoscopic proctitis, and in 10 of them sigmoid colon was also affected. The prevalence of colitis was 31 of 66 (47%) in patients treated for carcinoma of cervix and 19 of 86 (47%) in those treated for carcinoma of corpus. 41 (80.4%) had clinical symptoms (bleeding and diarrhea in 53% each). The mean time lag between radiation therapy and beginning of symptoms was 9 months. Histology was positive in only 24 (47.1%) of 51 endoscopically documented cases of proctocolitis. There was no increase in the prevalence of radiation injury after previous surgery of any kind. Nor was higher risk found in patients with hypertension, diabetes, or congestive heart failure. However, patients with low body mass were at increased risk (p less than 0.01). There was a dose-response relationship between total dose and endoscopic proctitis (p less than 0.001). The incidence was 0% below 40 Gy, 20% at 60 Gy and 50% at 90 Gy.
