Enlargement of the distance between tumor and adjacent normal tissue/organs (Organs at risk=OAR) by interventional insertion of balloon catheters RAD317

Conditions

Secondary malignant neoplasm of large intestine and rectum
C78.5
C22.0
Liver cell carcinoma
Intrahepatic bile duct carcinoma
Registration Number

Brief Summary

Results: In 31 cases, at least one balloon catheter was administered. The mean D1cc of the OAR in the group with balloon(s) was 12.6 Gy compared with 16 Gy in the virtual cohort without the device, therefore significantly lower (p < 0.001). Overall, there were no acute complications. Severe (> 2 CTCAEv4.03) late complications observed in 3/31 (9.6%) patients during follow-up period after brachytherapy were most certainly not due to the balloon application. Side effects were probably associated with pre-existing serious diseases and potentially additional local late effects of the irradiation in general rather than with the balloon catheters. Conclusions: The distancing of the adjacent OARs allows a higher D100 value of CTV, therefore allowing for more efficient local control.
