[Carcinomatous neuropathy in recurrent rectal carcinoma. The results of radiotherapy and the role of CT].
More than 60% of the patients with recurrent rectal carcinoma complain of pain after radical surgery. Pelvic carcinomatous neuropathy (PCN) is a frequent cause of pain in such patients. Although the effectiveness of radiotherapy in the palliative treatment of local recurrences of rectal carcinoma is well recognized, its results in PCN are less known. The authors have evaluated the results of high-energy radiotherapy in 12 patients with recurrent rectal carcinoma and PCN, who were treated with doses between 35 and 55 Gy. Although the survival of these patients is always poor, about 50% of them achieved a significant and prolonged palliative result by radiation treatment. In patients with PCN, CT is an effective tool to detect recurrences, define their volume and relationship to critical organs, show sites of neural involvement, and optimize radiation treatment planning.
