Although the transurethral resection of bladder tumor (TURBT) followed by intravesical chemotherapy is a conservative strategy for treatment of T1G3 bladder cancer, a relatively high risk of tumor recurrence and progression remains regarding the therapy. This study aimed to compare the efficacy of intravenous chemotherapy combined with intravesical chemotherapy versus intravesical chemotherapy alone for T1G3 bladder cancer after TURBT surgery. Methods: We retrospectively reviewed the cases of 457 patients who were newly diagnosed with T1G3 bladder urothelial carcinoma between January 2009 and March 2014. After TURBT, 281 patients received intravesical chemotherapy alone, whereas 176 patients underwent intravesical chemotherapy in combination with intravenous chemotherapy. Tumor recurrence and progression were monitored periodically by urine cytology and cystoscopy in follow-up. Recurrence-free survival and progression-free survival of the two chemotherapy strategies following TURBT were analyzed. Univariable and multivariable Cox hazards analyses were performed to predict the prognostic factors for tumor recurrence and progression. Results: The tumor recurrence rate was 36.7% for patients who received intravesical chemotherapy alone after TURBT, compared with 19.9% for patients who received intravenous chemotherapy combined with intravesical chemotherapy after TURBT (P<0.001). The progression rate was 10.6% for patients who underwent intravesical chemotherapy alone and 2.3% for patients who underwent the combined chemotherapies (P=0.003). Kaplan–Meier curves showed significant differences in recurrence-free survival and progression-free survival between the two treatment strategies, with a log-rank P-value of <0.001 and 0.003, respectively. Multivariable analyses revealed that intravenous chemotherapy was the independent prognostic factor for tumor recurrence and progression in the cohort. Conclusion: Intravenous chemotherapy combined with intravesical chemotherapy offers a better oncologic outcome than the intravesical chemotherapy alone for patients with T1G3 bladder urothelial carcinoma after TURBT, and it may be considered as a new therapy strategy for T1G3 bladder cancer.
