A longitudinal evaluation of improvements in treatment plan quality for lung cancer with volumetric modulated arc therapy.

ABSTRACT:

Purpose

To investigate planning time and number of optimizations in routine clinical lung cancer plans based on the plan quality improvements following each optimization.

Materials and method

We selected 40 patients with lung cancer who were treated with conventional fractionated radiotherapy (CFRT). The 40 plans (divided into two groups with one or two target volumes) were completed by 9 planners using volumetric modulated arc therapy (VMAT). A planning strategy, including technique script for each group and a planning process for data collection, was introduced. The total planning time, number of optimizations, and dose-volume parameters of each plan were recorded and analyzed. A plan quality metric (PQM) was defined according to the clinical constraints.
