To stduy the association between the prognosis of Ta transitional cell carcinoma (TCC) of the bladder and risk-related factors.Methods A total of 88 cases (62 males and 26 females;mean age,61 years;age range,41-81 years) of initial T.TCC of the bladder treated with transurethral resection of bladder tumor (TURBt) plus intravesical chemotherapy or immunotherapy were enrolled.Among them,there were 26 cases of G1,61 cases of G2 and 1 case of G3.For tumor site,62 cases (16 cases of G1,45 of G2,1 of G3) had single tumor and 26 cases (10 cases of G1,16 of G2) had multi-site tumors.The mean follow-up was 113 months (range,56-168 months).The tumor grade,original tumor number and their association with the recurrence and progression of this type of TCC were retrospectively analyzed.Results The overall recurrence rate (RR) was 60% (53/88).In single tumor group,RR of G1 cases was 25% (4/16);RR of G2 cases was 62% (28/45) and the total RR was 52% (32/62).In multi-site tumor group,RR of G1 cases was 80% (8/10),RR of G2 cases was 75% (12/16) and the total RR was 77% (20/26).The RR of multi-site tumor group was significantly higher than that of single tumor group (P<0.01).In single tumor group,RR of G2 cases was significantly higher than that of G1 cases (P<0.001).In multi-site tumor group,there was no association of RR with tumor grade.There was no progression in G1 tumor cases.The progression rate was 42.5% (17/40) in G2 tumor cases;among them,30% (12/40) progressed to T1G2 tumors and 12.5% (5/40) progressed to T2G2 tumors.The RR of cases who received thiotepa,mitomycin and BCG were 75% (12/16),68% (30/44) and 40% (11/27),respectively.Tumor specific mortality was 1.14% (1/88,a T2G3 case).Conclusion The multi-site Ta TCC of the bladder has relatively higher RR and greater chance of progression after the treatment of TURBt plus intravesical chemotherapy or immunotherapy,especially in the poor differentiated tumors,thus active treatment and close follow-up are essential in clinical practice.9 refs.
