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

July 10, 2018 updated by: Michele Fiore, Campus Bio-Medico University

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

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.

Detailed Description

Concurrent chemoradiation is the standard of care for patients affected by locally advanced (LA) NSCLC. Its superiority over radiotherapy alone or sequential chemoradiation has been proved in multiple phase III randomized trials. In a meta-analysis of six randomized studies, concurrent chemoradiotherapy decreased locoregional progression by 6.1% at 5 years when compared with sequential chemoradiation. This resulted in an improvement in overall survival of 4.5% at 5 years that was possibly directly related to locoregional control. Many patients however succumb to locoregional failure or distant metastases. Thanks to modern radiotherapy techniques, some strategies manage the geometrical uncertainties of imaging, treatment planning, and treatment delivery and thereby improve target coverage with a much steeper dose gradient and less irradiated normal tissue. The introduction of image-guided radiotherapy reveals the occurrence of target changes during treatment, and although the percentage of patients who experienced regression is not high (range 25%-40%), the degree of regression is in the range of 29% to 40%, corresponding to a rate of tumor shrinkage per fraction of 0.79% to 1.65%. Anatomical changes during radiotherapy might introduce discrepancies between the planned and delivered dose. Currently, the literature reports only dosimetric experiences and lacks clinical data on outcome when patients are treated with the adaptive approach. This study aims to investigate the failure pattern in patients with LA NSCLC treated with concurrent chemoradiotherapy with an adaptive approach, in particular, to evaluate the risk for local recurrence in the area excluded during replanning.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Radiotherapy Group
Patients with LA NSCLC treated with concurrent chemoradiation will be enrolled. During treatment all patients will undergo weekly chest CT simulations without intravenous contrast to assess acute toxicity and tumor shrinkage, and they will be all visualized by two radiation oncologists independently. For all CT simulations, each physician will be able to judge whether reduction will be (1) present and clinically significant, (2) present and clinically non significant, or (3) absent. In the case of physician agreement for the first category, a contrast-enhanced CT will be performed to better visualize node reduction, a new target volume will be delineated, and a new treatment plan (replanning study) performed. Patients will be treated without any time break.
Radiation: 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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of Local Recurrence and Pattern of Failure
Time Frame: three months
Patients are not considered to have local-regional control unless they achieve at least a partial response of their primary tumor or stable disease by imaging. Patients who do not achieve objective response are considered to have local-regional failure. Local-regional control rates are analyzed using the Kaplan-Meier method. Local recurrences are defined according to a dimensional and metabolic increase at chest CT with intravenous contrast and fludeoxyglucose F 18 (FDG) PET/CT. Recurrences are identified visually and independently by three radiation oncologists with the same method. The modality for definition of failures is readjusted with these definitions: "in-field failure" when a dimensional and/or metabolic progression is reported within the replanning PTV; "marginal failure" in cases of recurrence in the initial PTV but not in the replanning PTV, and "out-of-field failure" if the recurrence occurs outside the initial PTV.
three months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Response evaluation
Time Frame: three months
Response evaluation is defined according to the Response Evaluation Criteria in Solid Tumors criteria for complete and partial response, progression, and stable disease.
three months
Overall Survival
Time Frame: three years
Overall Survival is determined from the day of the diagnosis to the death, or to the last follow-up if no event is observed
three years
Progression-Free Survival
Time Frame: three years
Progression-free survival is obtained from the beginning of treatment to the observation of progression/recurrence, or to the last follow-up if no event is observed.
