Local recurrence of rectal adenocarcinoma after 'curative' surgery with and without preoperative radiotherapy.
The natural history of locally recurrent rectal cancer was analysed to assess whether preoperative irradiation altered the clinical course of the disease. In a randomized controlled trial of 849 patients, the value of preoperative radiotherapy in those with operable rectal adenocarcinoma was examined. After a minimum follow-up of 4 years, 156 patients who developed local recurrence were studied retrospectively. There were no differences concerning symptoms and the site of local recurrence between irradiated and non-irradiated patients. Curative treatment was rarely possible and median survival was only about 1 year, irrespective of adjuvant treatment. Local recurrence was the only manifestation of disease in 30-50 per cent of patients. An earlier and more aggressive surgical approach might improve survival.
