Adaptive Radiotherapy in Locally Advanced Non-Small Cell Lung Cancer (LARTIA Trial)

NCT03583723 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

Summary

Anatomical change of tumor during radiotherapy contributes to target missing. However, in the case of tumor shrinkage, adaptation of volume could result in an increased incidence of recurrence in the area of target reduction. This study aims to investigate the incidence of failure of the adaptive approach in Locally Advanced Non-Small Cell Lung Cancer and, in particular, the risk for local recurrence in the area excluded after replanning.

Radiotherapy Group

Patients will be immobilized with customized devices. Either four-dimensional CT or slow CT images using a multislice CT scanner will be acquired to evaluate internal target motion. Initially, gross tumor volume (GTV) will be determined in the maximum intensity projection on the initial size of the tumor and involved lymph nodal sites defined as PET-positive nodes and/or a node diameter greater than 1 cm, clinical target volume (CTV) will be defined as equal to the GTV plus node-positive stations and hilar stations, and planning target volume (PTV) will be created equal to the CTV plus a 0.5-cm safety margin. Treatment will be performed with a linear accelerator in a photon regimen, with a 6-to 15-megavolt (MV) nominal energy and three-dimensional (3D) conformal technique.
