简要总结
The objective is to investigate the efficacy and safety of four cycles of ddMVAC with G-CSF support in patients with MIBC and locally advanced UC
详细描述
- Currently, most treatment guidelines including NCCN recommend a neoadjuvant chemotherapy (NAC) as a standard of care in muscle invasive bladder cancer (MIBC).
- Although standard NAC regimen is controversial due to rare of head to head study between each regimens, cisplatin based multidrug combination regimens such as MVAC, GP, and dose dense MVAC (ddMVAC) with G-CSF supports are regarded as a backbone treatment on the basis of the results from previous studies.
- Application of NAC is still relatively slow adoption in real practice. These slow adoption result from intuitive concerns such as significant toxicity of multidrug combination chemotherapy represented by MVAC and delayed application of radical surgical treatment in non-responder
- The ddMVAC with G-CSF support regimen showed an improved efficacy compared with GP regimen, and tolerable compared with standard MVAC using application of routine G-CSF support and high intensity of cisplatin.
- In case of clinically lymph node evolvement (cN+) is not for strict NAC, but patient with cN+ UC have been treated induction chemotherapy of similar NAC regimens and surgical treatment. So, this study included MIBC plus cN+ UC as locally advanced UC.
- In Korea, there is a low adoption of NAC, additionally rare of ddMVAC with G-CFS in locally advanced UC. It is supposed concerns related with toxicity of ddMVAC. Although the concern is likely not true considering the previous result of the Western, there has not been studied ddMVAC as NAC in Asian including Korean.
- The objective of this trial is to assess the efficacy and safety of four cycles of ddMVAC with G-CSF support in patients with locally advanced UC.

排除标准
- •Histologic types other than urothelial cell carcinoma should be excluded. However, urothelial cell types combined with squamous or glandular features are allowed.
