Abstract：Objective To compare the dosimetric differences between two treatment planning systems (uRT-TPOIS and Monaco)
in volumetric modulated arc therapy (VMAT) for lung cancer and to provide a reference for clinical application. Methods Sixteen
patients with lung cancer who received treatment in the Department of Radiotherapy in Henan University People’s Hospital were
selected to design VMAT plan using Monaco 5.11 and uRT-TPOIS treatment planning systems, respectively, and the target areas
and organs at risk (OARs) exposure dose, conformity index (CI), heterogeneity index and the number of machine between the two
plans were compared. Results The Dmean and Dmin doses were higher in the Monaco plan compared to the uRT-TPOIS plan, the
difference was statistically significant (P<0.05). V95 in Monaco plan was significantly lower than that in uRT-TPOIS plan, and V107
was increased, the difference was statistically significant (P<0.05). There was no statistically significant difference in V110 between
the two plans (P>0.05). The CI, lung V10, V5, Dmean, and heart V30, V40, and Dmean of the uRT-TPOIS plan were better than those of the
Monaco plan, the difference was statistically significant (P<0.05). Conclusion Both systems can meet the needs of VMAT planning
for lung cancer, but due to the influence of treatment planning system algorithms, accelerator multi-lobe collimator thickness, etc.,
there are differences between different treatment planning systems. In terms of OARs protection and target conformal degree, uRTTPOIS
plan is superior to Monaco plan.
