PURPOSE OF REVIEW
Nonmuscle invasive bladder cancer is a common malignancy, usually treated by transurethral resection and adjuvant intravesical instillations of chemotherapy or immunotherapy. Appropriate adjuvant treatment can be selected based on several prognostic factors that determine risk for recurrence or progression. We discuss options for first-line and second-line adjuvant therapy for nonmuscle invasive bladder cancer.
RECENT FINDINGS
Mitomycin-C and epirubicin are the mostly used adjuvant chemotherapeutic drugs for tumours of low and intermediate risk. Bacillus Calmette-Guérin remains first-choice therapy in high-risk nonmuscle invasive bladder cancer. Gemcitabine and apaziquone are especially promising for treatment of intermediate risk nonmuscle invasive bladder cancer but require further study. Device-assisted therapies, such as thermochemotherapy and electromotive drug administration, have yielded good results in high-risk nonmuscle invasive bladder cancer and could be considered second-line therapy in this setting.
SUMMARY
Primary problems in nonmuscle invasive bladder cancer are its tendency to recur and its elusiveness (especially high-risk nonmuscle invasive bladder cancer) of progression to muscle invasive disease. First-line adjuvant therapies are well established but suboptimal. Some second-line therapies are promising but should be used cautiously, because in some patients the best option is not always the conservative one.
综述目的
非肌层浸润性膀胱癌是一种常见的恶性肿瘤,通常采用经尿道切除术及辅助性膀胱内灌注化疗或免疫治疗。可根据多种决定复发或进展风险的预后因素选择合适的辅助治疗。我们讨论非肌层浸润性膀胱癌一线和二线辅助治疗的选择。
最新发现
丝裂霉素C和表柔比星是低风险和中风险肿瘤最常用的辅助化疗药物。卡介苗仍是高风险非肌层浸润性膀胱癌的首选治疗方法。吉西他滨和阿帕唑醌在治疗中风险非肌层浸润性膀胱癌方面尤其有前景,但需要进一步研究。设备辅助治疗,如热化疗和电动药物给药,在高风险非肌层浸润性膀胱癌中已取得良好效果,可在此情况下考虑作为二线治疗。
总结
非肌层浸润性膀胱癌的主要问题是其复发倾向以及进展为肌层浸润性疾病的隐匿性(尤其是高风险非肌层浸润性膀胱癌)。一线辅助治疗已确立,但并非最佳。一些二线治疗有前景,但应谨慎使用,因为在某些患者中,最佳选择并不总是保守治疗。
