title: [Scintigraphy with 67Ga-citrate and 111In-bleomycin in cancer of the rectum].
abstract: Scintigraphy with 67Ga-citrate and 111In-bleomycin was performed in 26 patients with primary rectal cancer, 176 patients with suspected recurrent tumors, and in 34 patients without clinicoroentgenological signs of cancer recurrence. A focus of higher accumulation of these radionuclides in the rectal area was recorded in all 26 patients. Of 176 patients with symptoms of recurrence tumors were detected by means of ultrasonic and computed tomography of the small pelvis in 158 patients. False-positive results were marked in 18 (10.2%) patients with chronic inflammatory processes at the site of the resected rectum, in anastomosis, and prostatic adenoma. In the control group of 34 patients false-positive results were marked in 8.8%. Positive scintigraphy used in combined diagnosis of rectal cancer recurrences holds promise.
