TWO CASES OF RADICALLY RESECTED LOCAL RECURRENT RECTAL CANCER DIAGNOSED BY CLINICAL SYMPTOMS, CT AND MRI IMAGINGS IN AN EARLY STAGE

The incidence of local recurrence after curative resection of the rectal cancer is considerably high, but, because of the delay in diagnosis of recurrence, surgical retreatment is difficult in most cases. This paper reports two cases of small local recurrence which were able to be resected radically following early diagnosis by clinical symptoms, CT, and magnetic resonance imaging (MRI) appearance. Case 1: A 70-year-old female who underwent a low anterior resection of the rectum two years and two months before, complained of lumbar pain. CT and MRI revealed a presacral small local recurrence. The tumor was resected by laparotomic-tumorectomy. Case 2: A 60-year-old male who underwent abdominoperineal resection of the rectum three years and nine months before, complained of perineal pain. From CT MRI imagings and an elavation in the serum CEA level, a small local recurrence in presacral region was detected. Transsacral-tumorectomy was performed. On both two cases, tumor was radically resected and the patients discharged without any complaints.
