Clinical investigation for recurrence and progression in Ta grades 1 and 2 bladder cancer

| Zusammenfassung: | We treated 107 new patients with stage Ta, grades 1 and 2 transitional cell bladder carcinoma by transurethral resection during the past 23 years. The clinicopathological factors evaluated were grade, size, number and form of tumor. Fifty-five patients (51%) had recurrent tumors after initial resection and progression (muscle invasion or metastasis) occurred in four patients (3.7%). The 5-year and 10-year recurrence free rates were 47.3 and 29.8%, respectively. Seven patients (6.5%) had grade 3 tumor (grade-up) at recurrence. An increase in T category to T1 (stage-up) occurred in 13 patients (12%), only one of whom later developed an invasive tumor (pT4). The size of tumor significantly affected the rate of recurrence (p < 0.01). Sessile tumor were at a significantly greater risk for progression (p < 0.05). Stage-up did not have a significant effect on progression, but grade-up was significantly risky for progression (p < 0.01). Initial grade 2 tumors were highly related to grade-up (p < 0.05) |
