Trial summary

This study is designed to characterize the effects of high energy radiation on bone breakdown, with a specific interest in reducing the rate of sacral fractures. Although radiation is very important in managing tumors, it is related to complications such as bone fractures. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • All laboratory tests that are a part of the eligibility criteria must be completed within 14 days prior to the date of registration. Diagnostic tests that are a part of the eligibility criteria must be performed within 30 days of the date of registration. Participants must meet the following criteria on screening examination to be eligible to participate in the study:
  • Study participants must have histologically confirmed primary malignant bone tumor in the sacrum for which surgery and radiation or radiation alone are planned.
  • Age 18 years or older. In children under the age of 8, tetracycline derivatives have been reported to stain tooth enamel yellow color. These considerations lead us to exclude young persons under the age of 18 from the study.
  • Participants must have normal organ and marrow function as defined below:
  • Total bilirubin within normal institutional limits
  • Aspartaataminotransferase (AST) (SGOT)/ Alanine-aminotransferase (ALT) (SGPT) < 2.5 X institutional upper limit of normal
Show all 9Show fewer
  • Creatinine within normal institutional limits or creatinine clearance > 60 mL/min/1.73 m2 for subjects with creatinine levels about institutional normal limit
  • The effects of tetracyclines and radiation used in computer tomography on the developing human fetus are known to be detrimental. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
  • Participants must be able to read and understand English language and have the ability to understand and the willingness to sign a written informed consent document.

Who cannot join

  • Participants who exhibit any of the following conditions at screening will not be eligible for admission into the study.
  • Participants who have had surgery, chemotherapy, or radiotherapy of the sacrum prior to entering the study
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to tetracyclines.
  • Pregnant or nursing
  • Uncontrolled inter current illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

About this study

Official title: Pilot Study of the Effect of High Doses of Radiation on Bone Metabolism and Structure in Patients Treated With Adjuvant Radiotherapy and Surgery for Sacral Tumors

This study is designed to characterize the effects of high energy radiation on bone breakdown, with a specific interest in reducing the rate of sacral fractures. Although radiation is very important in managing tumors, it is related to complications such as bone fractures. In this research study, the investigators are looking to determine changes in blood markers, bone density, and bone structure following radiation and to better understand the reason for these changes.

Read the detailed description

Participants in the Surgical Arm of the study will be treated according to the schedule outlined in protocol for a combined treatment with surgery and adjuvant high dose radiotherapy. Patients in the non surgical arm of the the study will be treated according to the protocol being treated with radiotherapy alone.

Being tested
Radiation (Surgical Arm), Radiation (Non-surgical Arm), Malignant Tumor Surgery
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Radiation (Surgical Arm)Radiation

    For surgical candidates, the standard treatment includes pre-operative radiation of 50.4 Gy, followed by a recovery period of approximately 4 to 5 weeks. After this surgery will take place. After approximately 6 weeks of recovery, to allow the surgical incision to heal, the patient is treated with another 19.8 Gy up to 27 Gy of radiation postoperatively depending on the final margin status (higher for gross residual disease)

  • Radiation (Non-surgical Arm)Radiation

    Non-surgical candidates receive 72 up to 77.14 Gy of radiation depending on the histology (72 Gy for osteosarcoma and chondrosarcoma and 77.4 Gy for chordoma)

  • Malignant Tumor SurgeryProcedure or surgery

    Surgery involves removing the malignant tumor in the sacrum in one piece, preferably with a cuff of normal tissue around the tumor

Malignant Tumor Surgery And RadiationExperimentalThe standard treatment includes pre-operative radiation of 50.4 Gy, followed by a recovery period of approximately 4 to 5 weeks. Surgery involves removing the malignant tumor in the sacrum in one piece, preferably with a cuff of normal tissue around the tumor. After approximately 6 weeks of recovery, the patient is treated with another 19.8 Gy up to 27 Gy of radiation postoperatively depending on the final margin status (higher for gross residual disease). If the wound is not healed or there is another medical reason to delay adjuvant radiation, then radiation may begin later.
Receives: Radiation: Radiation (Surgical Arm); Procedure: Malignant Tumor Surgery

Questions about this trial

What is this clinical trial studying?

A study testing Radiation (Surgical Arm), Radiation (Non-surgical Arm) and Malignant Tumor Surgery in people with Malignant Bone Tumors, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Bone Mineral Density (Tb. BMD) (time frame: Non-surgical arm: baseline, 3 months Surgical arm: baseline, 9 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Dec 2021; AzTrials last refreshed its copy on 7 Nov 2026.
