Adjuvant Intraarterial Chemotherapy Following Surgery to Treat Locally Advanced Bladder Cancer

Sun Yat-sen University186 enrolled

Overview

Effect of adjuvant intra-arterial chemotherapy to control tumor progression in patients cystectomized for locally advanced bladder cancer.

For locally advanced bladder cancer patients, tumor relapse rates after radial cystectomy were even as high as 50%-62%.Five-year disease-specific survival and OS rates in the organ-confined disease (defined as ≤pT3a) were 78.9% and 68%, respectively. For the non-organ-confined disease (defined as pT3b or higher), the rates were about 36.8% and 30.3%, respectively.Systemic chemotherapy can only prolong survival for up to 14.8 months, although with multiple severe adverse effects, such as neutrocytopenia, infection/sepsis, renal dysfunction, mucositis, or gastrointestinal toxicity. Additionally, the mortality rate associated with systemic chemotherapy was about 1%-4%.Therefore, the objective of our study was to determine if adjuvant intra-arterial chemotherapy with GC was able to reduce the systemic drug toxicities and yield a better clinical outcome.

Interventions

Surgery of percutaneous catheter systemPROCEDURE

Intraarterial (IA) catheterization was done in the Department of Invasive Technology. All medications were administered using percutaneous catheter system via a modified Seldinger technique. An angiographic catheter was inserted through the femoral artery into the internal iliac artery. The catheter tips were located superior to the origin of bilateral common artery.
