ABSTRACT

Purpose: To evaluate the role of ARDT after surgical resection of ACC.

Materials and Methods: Records of patients from our institutional ACC database were retrospectively assessed. A paired comparison analysis was used to evaluate the onco­logical outcomes between patients treated with surgery followed by ARDT or surgery only (control). The endpoints were LRFS, RFS, and OS. A systematic review of the literature and meta-analysis was also performed to evaluate local recurrence of ACC when ARDT was used.

Results: Ten patients were included in each Group. The median follow-up times were 32 months and 35 months for the ARDT and control Groups, respectively. The re­sults for LRFS (p=0.11), RFS (p=0.92), and OS (p=0.47) were similar among subsets. The mean time to present with local recurrence was significantly longer in the ARDT group compared with the control Group (419±206 days vs. 181±86 days, respectively; p=0.03). ARDT was well tolerated by the patients; there were no reports of late toxicity. The meta-analysis, which included four retrospective series, revealed that ARDT had a protective effect on LRFS (HR=0.4; CI=0.17-0.94).

Conclusions: ARDT may reduce the chance and prolong the time to ACC local recur­rence. However, there were no benefits for disease recurrence control or overall sur­vival for patients who underwent this complementary therapy.
