Multiple Myeloma Clinical Trial
Rapid Radiation Therapy for Painful Osseous Metastatic Disease
The purpose of this research study is to evaluate the safety and effectiveness of an experimental workflow that may result in a faster way to plan and deliver radiation for the treatment of pain caused by metastatic bone tumors (tumors that originally came from another organ and have spread to bones causing pain) or multiple myeloma (a type of cancer that begins in white blood cells that produce antibodies).
The current standard of care radiation treatment planning and delivery takes 2 to 3 weeks from start to finish. The investigators have developed an experimental workflow: a radiation treatment planning and delivery workflow called "STAT RT" (STAT means "right away", and RT means radiation therapy). This experimental workflow may shorten the time it takes to plan and treat painful bone metastases to 1 week or less. All steps in this process will be performed within the current standard of care but in a shorter time frame to allow treatment to start sooner.
The investigators will evaluate effectiveness by requesting patients to complete pain and quality of life questionnaires before and after treatment. The investigators will also be collecting additional information from their treatments that will help us make future workflows even more efficient.
Background: Osseous metastatic disease causes significant pain, decreased functioning, and decreased quality of life. Progressive bone destruction can lead to pathologic fractures or spinal cord compression leading to orthopedic surgery, paralysis, and/or patients becoming bedridden. Opioids can alleviate pain but have neurologic and gastrointestinal side effects that further decrease quality of life. Radiation therapy can effectively reduce pain and opioid use and prevent further bone destruction, however, its use is limited because the current workflow frequently requires one week for planning and two weeks for delivery. Additionally, typical palliative radiation plans for osseous metastases lack conformality of dose to the tumor volume, and therefore, result in radiation-induced toxicity to large volumes of adjacent normal tissue. Recent software and hardware advancements provide the opportunity to revolutionize the palliative treatment of osseous metastases. The investigators propose to investigate a novel TomoTherapy-based workflow, called STAT RT, which includes same day CT simulation, treatment planning, and quality assurance measurements coupled with highly conformal treatment delivery for patients with osseous metastases in a pilot clinical trial.
Objective: The overall goal of this STAT RT proposal is to develop a more rapid, convenient, and effective palliative radiation approach for patients with osseous metastases that is less toxic and less expensive than current treatment regimens. The investigators have already optimized the conformality of TomoTherapy-based radiation doses for osseous metastases, and the investigators have developed a STAT RT workflow that condenses standard of care simulation, planning, quality assurance, and treatment delivery into 5-6 hours. Additional optimization and integration of new radiation therapy computing processes will allow for real time simulation, planning, and delivery via a novel Scan-Plan-Treat STAT RT workflow that will ultimately require only 30 minutes. In this study the investigators will evaluate the effectiveness of the current STAT RT workflow, and the investigators will investigate techniques for further optimization that will be needed to create a 30 minute Scan-Plan-Treat STAT RT workflow.
Primary Specific Aim/ Hypothesis: The investigators will quantify the time for pain relief, amount of pain relief, opioid use reduction, functional scores, quality of life, and satisfaction of patients treated with STAT RT for osseous metastases. The investigators hypothesize that these patients will have rapid and significant pain relief, improved quality of life, and high patient satisfaction.
Secondary Specific Aim/ Hypothesis: The investigators will optimize the integration of commercially available and in-development software to develop the Scan-Plan-Treat STAT RT workflow. Specifically, the investigators will A) optimize rigid and deformable co-registration of pre-contoured diagnostic image sets to MVCT simulation scans and compare the accuracy to the same pre-contoured diagnostic image sets co-registered to kilovoltage CT (kVCT) simulation images and then kVCT simulation to MVCT scan co-registration, B) optimize CT-detector-based exit dose measurement algorithms for quality assurance and compare to standard of care phantom-based quality assurance, C) optimize the accuracy of an in-house real time infrared tracking system for intrafractional patient position monitoring to ensure accurate patient treatment. The investigators hypothesize that these new components will provide effective and efficient methods for treatment planning, quality assurance, and patient position monitoring that can be used in a future 30 minute Scan-Plan-Treat STAT RT workflow.
Study design: The investigators will recruit 30 cancer patients with 1-3 painful osseous metastatic lesions (target sites) who are candidates for palliative radiation therapy. Patients will receive 1-5 fractions of 5-8 Gray (Gy) (minimum biologic effective dose of 25 Gy) of conformal radiation therapy delivered to the target sites via the Helical TomoTherapy system using the STAT RT workflow. Data will be collected to evaluate the effectiveness of our novel image co-registration techniques, CT-detector-based exit dose calculations, and infrared patient position monitoring. These novel techniques for image co-registration, radiation dose calculations, and patient position monitoring will not alter or replace standard of care techniques. Using validated surveys the investigators will record patient pain, analgesic use, function, quality of life, and patient satisfaction prior to treatment and at 1 week, 4 weeks, 8 weeks, 12 weeks, 6 months, and 12 months after therapy. Radiation-induced treatment related toxicities will be captured during treatment and at the above time points.
