Comparative analysis of SmartArc‐based dual arc volumetric‐modulated arc radiotherapy (VMAT) versus intensity‐modulated radiotherapy (IMRT) for nasopharyngeal carcinoma

Abstract: The purpose of this study was to evaluate and quantify the planning performance of SmartArc‐based volumetric‐modulated arc radiotherapy (VMAT) versus fixed‐beam intensity‐modulated radiotherapy (IMRT) for nasopharyngeal carcinoma (NPC) using a sequential mode treatment plan. The plan quality and performance of dual arc‐VMAT (DA‐VMAT) using the Pinnacle3 Smart‐Arc system (clinical version 9.0; Philips, Fitchburg, WI, USA) were evaluated and compared with those of seven‐field (7F)‐IMRT in 18 consecutive NPC pati… Show more

“…On the other hand, the use of a different planning and delivery system might also lead to different results. Lee et al (7) found that slightly better sparing for the majority of the OARs except spinal cord and oral cavity by using SmartArc‐based dual‐arc VMAT compared to seven‐field step‐and‐shoot IMRT for NPC. Our investigation focused merely on early‐stage NPC proved that the use of triple‐arc RA produced comparable dose conformity and target dose homogeneity, as well as better sparing of the parotid glands, spinal cord, PRV spinal cord, and PRV brain stem compared with nine‐field sliding window IMRT.…”

“…The study of Verbakel et al (3) concluded that double‐arc RA produced better dose homogeneity than single‐arc RA and seven‐field sliding window IMRT for head and neck cases. Lee et al (7) concluded that dual‐arc SmartArc VMAT produced better target dose homogeneity than conventional seven‐field IMRT for NPC cases. Our results showed that RA plans produced more hot areas when compared with IMRT plans.…”

“…Selected radiobiological parameters for normal tissue calculations (gEUD and NTCP). Values were obtained from AAPM TG-166 report and the studies by Burman et al, (58) Stavrev et al, (59) Huang et al, (60) and Lee et al (61) Parameters a α/β (Gy) TD 50 …”

“…Selected α/β values were 3 Gy for all the cases. Values for TD 50 , γ 50 , m, and n parameters were shown in the previous report, taken from the study by Burman et al (58) Additional γ 50 parameters were taken from studies by Stavrev et al (59) (cord and mandible), Huang et al (60) (inner ear), and Lee et al (61) (parotid gland). The γ 50 parameter for the pubic bone was taken as 4, similar to the value for the femoral head.…”
