Intensity-modulated Radiotherapy With Integrated-boost in Patients With Spinal Bone Metastases (IRON-2)

July 12, 2016 updated by: Heidelberg University
The primary goal of the study is to determine the local control-rate after radiotherapy (RT) with and without simultaneous integrated boost (SIB) concepts in patients with bone metastases of the spine. Further study objectives are survival, and clinical parameters such as pain, quality of life (QoL) and fatigue. We expect an improvement in local control and consecutively an increased re-sclerotization of the bone metastasis due to a higher biological dose in the tumor area. Therefore patients could benefit in quality-of-life, pain relief and mobility.

Detailed Description

The vertebral column is the main localization of bone metastases and is where they frequently indicate an advanced stage of a malignant primary disease [1, 2]. Two thirds of all patients with tumors are estimated to develop bone metastases in the course of their disease [3]. Spinal bone metastases are of central impact for patients in a palliative setting. The clinical symptoms include pain at rest and under exercise but also impaired activity of daily life, the risk of pathological fractures, and neurological deficits. Local control is the essential factor for stability of the vertebral body of patients with spinal bone metastases. In regard to re-calcification of former osteolytic lesions, palliative radiotherapy (RT) represents an effective treatment option [4]. The most common schedule was specified as 30 Gy in 10 fractions. Stereotactic body radiation therapy (SBRT) using intensity-modulated radiotherapy (IMRT) can be a safe modality for treating spinal metastasis with enhanced targeting accuracy [5]. Secondly, IMRT to the spine was well tolerated (especially in the spinal cord), had no significant late toxicities, and spared other organs at risk simultaneously [6]. The main problem of the standard schedule is the limited dose application to the metastasis due to organ at risk myelon. Therefore, the aims of this study is to apply a high biological dose in the tumor region and to achieve an improved result related to local control for palliative patients with painful spinal bone metastases. Secondly, the aim is to evaluate QoL, fatigue, and survival of three different RT-techniques. To the best of our knowledge, no comparable randomized study has been described in the literature so far.

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.

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.
