Abstract

Superficial bladder tumors are usually treated by TUR and the result of this treatment was known to have good prognosis. However, recurrence of the tumor after complete resection occurs in about 40-70% of the patients, a significant percentage of these recurrences showing a higher degree of malignancy. There are many factors affecting the recurrence and progression. Understanding the aspect of recurrence will help in the management of patients. So we studied to evaluate the relationship in 43 cases with superficial bladder tumors admitted to the Department of Urology, Inje college of Medicine, Pusan Baik Hospital during the period from April, l981 through March, l986. Thirty three patients were followed up for more than 3 Months. Following results were obtained: 1. No. of patients with recurrence was l8 (54.5 %). 2. Nine cases (50%) were recurred within 1 year and these patients had poor prognosis than patients recurred after 1 year. 3. The recurrence around the initial tumor site were 6 cases (33.3 %) and these patients had poor prognosis than recurrence at other site. 4. There was more significant increase of malignant progression and recurrence in multiple tumor or large tumor than solitary or small one. 5. There was significant increase of malignant progression and recurrence in initial high grade tumor than low grade tumor. 6. The recurrence rate was decreased in patients instilled adriamycin more than 4 times (45.5%, than less than 4 times (75%).
