The Role of Serum Cytokeratin 19 Fragment in Transarterial Infusion against Invasive Bladder Cancer
Abstract: Background: We used transcatheter arterial infusion chemotherapy (TAI) for patients with T1G3 and greater than T2 bladder cancer, which was diagnosed after extensive and deep transurethral resection of bladder tumor (TUR-BT), and we investigated the utility of serum cytokeratin 19 fragment (CYFRA) as a predictive factor of the response to therapy. Material and Methods: From November 2001 to November 2010, 56 patients (46 males and 10 females) with pathologically confirmed T1 G3 or greater than T2 bladder cancer after TUR-BT underwent two courses of TAI of cisplatin, methotrexate and doxorubicin as neoadjuvant setting. Then, patients underwent evaluation TUR-BT. Thereafter, the bladder was preserved in patients with superficial or undetectable tumors on TUR-BT. Advanced cases and residual bladder tumor cases were treated with total cystectomy or systemic chemotherapy. CYFRA levels were measured before and after performing TAI. Results: With this therapy, the 5-year survival rate was 85.7% in pT1G3, 82.3% in pT2, and 66.6% in greater than pT3 cases. Bladder preservation with no recurrence was observed in 58.7% of the patients. Grade III adverse events included leucopenia (6/56 patients: 10.7%). Serum CYFRA levels significantly decreased with treatment (in 4/6 patients with elevated CYFRA levels). Conclusion: These results suggest that although total cystictomy is usually indicated for T1G3 bladder cancers, bladder preservation and control of micrometastases can be achieved by performing TAI after extensive and deep TUR-BT. Our results also suggest the utility of monitoring serum CYFRA to assess the response to therapy.
