**SUPPLEMENTARY INFORMATION:**
The Agency for Healthcare Research and Quality has commissioned the Evidence-based Practice Center (EPC) Program to complete a review of the evidence for *Radiation Therapy for Bone Metastases.* AHRQ is conducting this systematic review pursuant to Section 902 of the Public Health Service Act, 42 U.S.C. 299a.
The EPC Program is dedicated to identifying as many studies as possible that are relevant to the questions for each of its reviews. In order to do so, we are supplementing the usual manual and electronic database searches of the literature by requesting information from the public ( *e.g.,* details of studies conducted). We are looking for studies that report on Radiation Therapy for Bone Metastases, including those that describe adverse events. The entire research protocol is available online at: *https://effectivehealthcare.ahrq.gov/products/radiation-therapy-bone-metastases/protocol.*
This is to notify the public that the EPC Program would find the following information on Radiation Therapy for Bone Metastases helpful:
A list of completed studies that your organization has sponsored for this indication. In the list, please *indicate whether results are available on ClinicalTrials.gov along with the ClinicalTrials.gov trial number.*
*For completed studies that do not have results on ClinicalTrials.gov,* a summary, including the following elements: study number, study period, design, methodology, indication and diagnosis, proper use instructions, inclusion and exclusion criteria, primary and secondary outcomes, baseline characteristics, number of patients screened/eligible/enrolled/lost to follow-up/withdrawn/analyzed, effectiveness/efficacy, and safety results.
*A list of ongoing studies that your organization has sponsored for this indication.* In the list, please provide the *ClinicalTrials.gov* trial number or, if the trial is not registered, the protocol for the study including a study number, the study period, design, methodology, indication and diagnosis, proper use instructions, inclusion and exclusion criteria, and primary and secondary outcomes.
Description of whether the above studies constitute *ALL Phase II and above clinical trials* sponsored by your organization for this indication and an index outlining the relevant information in each submitted file.
Your contribution is very beneficial to the Program. Materials submitted must be publicly available or able to be made public. Materials that are considered confidential; marketing materials; study types not included in the review; or information on indications not included in the review cannot be used by the EPC Program. This is a voluntary request for information, and all costs for complying with this request must be borne by the submitter.
The draft of this review will be posted on AHRQ's EPC Program website and available for public comment for a period of 4 weeks. If you would like to be notified when the draft is posted, please sign up for the email list at: *https://www.effectivehealthcare.ahrq.gov/email-updates.*
*The systematic review will answer the following questions. This information is provided as background. AHRQ is not requesting that the public provide answers to these questions.*
**Key Questions (KQ)**
*KQ 1:* What is the effectiveness and what are the harms of external beam radiation therapy (EBRT) in the palliative treatment of bone metastases in symptomatic adults when combined with additional therapies ( *e.g.,* surgery, radionuclide therapy, bisphosphonate therapy, ablation kyphoplasty/vertebroplasty) compared with EBRT alone?
*KQ 2:* For symptomatic adults with bone metastases who will receive initial radiation for palliation, what is the comparative effectiveness and what are the comparative harms of dose-fractionation schemes and techniques for delivery ( *e.g.,* three-dimensional conformal radiation therapy, stereotactic body radiation)?
*KQ 3:* For symptomatic adults with bone metastases who will receive re-irradiation for palliation, what is the comparative effectiveness and what are the comparative harms of dose-fractionation schemes and techniques for delivery ( *e.g.,* three-dimensional conformal radiation therapy, stereotactic body radiation)?
**Contextual Questions (CQ)**
*CQ 1:* What are common barriers and facilitators to implementing guidance in radiation oncology, specifically related to palliative radiation for metastatic bone disease (MBD)?
*CQ 2:* What strategies could be used to promote the use and implementation of guidance in radiation oncology, specifically related to palliative radiation for MBD?
*CQ 3:* In symptomatic patients considered for palliative radiation therapy for MBD, to what extent does patient financial distress/hardship differ between EBRT dose/fraction schemes or technique?
| | Inclusion | Exclusion |
| --- | --- | --- |
| Population | Symptomatic adults with cancer that has metastasized to the bone | • Patients <18 years old. |
| | Symptomatic adults with bone metastases who will receive re-radiation for palliation | |
| | Consider patient and clinical characteristics (
age, sex, social determinants of health, primary tumor histology, site of metastases) | |
| Interventions | External beam radiation therapy for the palliative management of bone metastasis
additional therapies (
surgery, radionuclide therapy, bisphosphonate therapy, ablation, kyphoplasty/vertebroplasty) | Proton beam therapy. |
| | Comparisons of dose-fractionation schemes for EBRT, comparisons of EBRT techniques (
conventional RT vs. SBRT, SBRT vs. IMRT) | |
| Comparators | No cointervention (
EBRT alone) | |
| | Comparisons of dose-fractionation schemes, comparisons of EBRT modalities/techniques | |
| Outcomes | | • Non-validated measurement instruments for clinician or patient rated outcomes (
pain, function, HRQOL). |
| | Additional (secondary) outcomes: | |
| | Harms (
rate of radiation/treatment toxicity, radiation-induced fracture rates, reduced mobility, reduced independence), adverse events (pain flare, radiation recall, fatigue, skin changes, etc.) | |
| Timing | Any (timing may depend on treatments provided and outcomes assessed) | None. |
| Setting | Any | None. |
| Study design and publication dates | Focus will be on the best evidence available that permits direct comparisons to answer key questions | |
Dated: July 6, 2022.
