Colorectal Pulmonary Metastases: Pulmonary Metastasectomy Versus Stereotactic Ablative Radiotherapy: a Phase III Multicenter Randomized Controlled Trial

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is formally endorsed by the Dutch Society of Lung Surgery (NVvL), the Dutch Society of Cardiothoracic Surgery (NVT), the Dutch Society of Radiation Oncology (NVRO). The main objective of the proposed randomized trial is to compare efficacy of SABR to the efficacy of metastasectomy with regards to the primary endpoint (local recurrence free survival at 5 years) in patients with limited colorectal pulmonary metastases. This will determine the most effective local treatment modality. The investigators hypothesize that patients with limited colorectal pulmonary metastases will have non-inferior overall survival after pulmonary metastasectomy compared to SABR, however metastasectomy will result in superior local recurrence free survival at five years when compared to SABR. In addition, the investigators hypothesize that SABR is associated with lower morbidity, comparable quality of life and comparable health care costs compared to metastasectomy. Recurrent metastases are preferably treated by the index treatment to which the patient was randomized, local recurrent metastases are preferably treated by means of cross-over between both arms. Comparing metastasectomy to SABR for patients with colorectal pulmonary metastases will present the international community the evidence needed to better select patients for local radical treatment, while diminishing uncertainty for patients and care givers.

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.

Ages Eligible for Study

  • Adult
