Abstract:
Objective To investigate curative efficacy of RevoLix 2 μm laser in combined with pirarubicine in the treatment of non-muscular invasive bladder cancer and its effects on level of serum vascular endothelial growth factor (VEGF).Methods 115 cases with non-muscular invasive bladder cancer who received therapy in our hospital from January 2012 to April 2013 were selected as research objects to retrospectively analyze their materials.According to therapeutic schemes,patients were divided into group A ( n=52 ) and group B ( n =63 ).Group A was given electrocision of bladder tumor and perfusion of pirarubicine 30 mg in 5% glucose injection 30 mL,one times per week,for eight weeks,and then one times per month,a total of one year; while group B was given RevoLix 2μm laser resection of bladder tumor and perfusion of pirarubicine 30 mg in 5% glucose injection 30 mL,one times per week, for eight week, and then one times per month, a total of one year.Then, operation status, incidence of complications after operation,level of VEGF and recurrence rate between the two groups were observed and compared.Results Compared with group A, group B had statistically less bleeding volume,shorter retention time of urinary tube and hospitalization time (P<0.05),while operation time in the two groups was statistically same.After operation,incidence of complications in group B was 3.2%,which was statistically lower than that of 15.4% in group A ( P<0.05).On admission and 1 week after operation,levels of VEGF of two groups had no significant differences.8 weeks and 6 months after operation,level of VEGF in group B was statistically lower than that in group A respectively (P<0.05).After the two-year follow-up,recurrence rate in group B was 4.8%,which was statistically lower than that of 17.3% in group A (P<0.05).Conclusion RevoLix 2μm laser combined with pirarubicine is effective for patients with non-muscular invasive bladder cancer with less bleeding volume,quicker postoperative recovery,lower incidence of complications and recurrence rate after operation.This may be related to the decrease of serum VEGF level in patients,it is necessary to further study.
