Eclipse version 16

In this study, a customized 3D-printed bolus was used on two patients with SCC in their distal extremities who were treated at Gangneung Asan Hospital. The patient characteristics are summarized in Table 1. The patients were treated with a 6 MeV high-energy photon beam. For Patient 1, the treatment was planned to be performed twice and a total of 240 and 265 monitor units (MU) were set to be delivered to the primary and secondary irradiation, respectively. For Patient 2, a total of 235 MU was set to be delivered. The planning of the 3D conformal radiation therapy (3D CRT) was performed using Eclipse version 16.1 (Varian, Palo Alto, Santa Clara, CA, USA) and treatment was performed using Varian Clinac iX (Varian, Palo Alto).

All plans were exported to the Eclipse version 16.1 (Varian Medical Systems), and dose–volumetric indices (DVIs) in the stomach, duodenum, GTV, and CTV were examined for the ART and SCH fractions.
These DVIs were analyzed statistically between the ADP and SCH fractions using the Wilcoxon rank sum test. The significance level was set at 5%. All statistical analyses were conducted using EZR (Saitama Medical Center, Jichi Medical University, Japan).
