Purpose:
The aim of this study was to evaluate the effect of high-dose-rate intraoperative radiation therapy (HDR-IORT) in a multimodality treatment on the local control (LC) and the overall survival (OS) rate in locally advanced rectal cancer (LARC), locally recurrent rectal cancer (LRRC) and recurrent intra-abdominal sarcomas (RS).
Materials And Methods:
A retrospective analysis was performed on 27 patients who were treated with radical resection and HDR-IORT between April 2007 and January 2017. Patient, tumor and surgical characteristics were analyzed and the perioperative (<30 days) and long-term complications (>30 days) were assessed and graded.
Results:
None of the patients with LARC (n = 4) developed a local recurrence and all patients were still alive at the end of the follow-up. The LC rates of LRRC (n = 17) after one and three years were respectively 48% and 40% and the one, three and five years OS were respectively 93%, 62% and 44%. For RS (n = 6), the LC rates after one and three years were both 33% and the one and three years OS rate were respectively 83% and 46%.
Conclusions:
The results of our study show that HDR-IORT could be a valuable asset in the multimodality management of LARC, LRRC and RS.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
