Thoracotomy Versus Thoracoscopic Management of Pulmonary Metastases in Patients With Osteosarcoma
What this study is about
This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases).
View original scientific description
This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer.

Primary outcome measures
Thoracic event-free survival (tEFS)
Time frame: Four years after enrollment
Estimated four year thoracic event free survival (tEFS) where tEFS is calculated as the time from study enrollment to thoracic cavity event. Any recurrence within the pulmonary parenchyma, involving the pleural surface or the drain/surgical site wound will be considered an event. A death that results from the procedure, as confirmed by the treating physician, will be considered an event. Patients with recurrences arising outside the thoracic region, the diagnosis of a malignancy that is not osteosarcoma (SMN) or death considered unrelated to the study surgical procedure, as confirmed by the treating physician will be considered competing events provided these occur prior to a thoracic cavity event as defined above. Patients without an event of any kind at last contact are considered censored.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients must be \< 50 years at the time of enrollment.
- Patients must have =\< 4 nodules per lung consistent with or suspicious for metastases, with at least one of which being \>= 3 mm and all of which must be =\< 3 cm size.
- Note: Patient must have eligibility confirmed by rapid central imaging review.
- Lung nodules must be considered resectable by either open thoracotomy or thoracoscopic surgery. Determination of resectability is made by the institutional surgeon.
- Patients must have a histological diagnosis of osteosarcoma.
- Patients must have evidence of metastatic lung disease at the time of initial diagnosis, or at time of 1st recurrence following completion of therapy for initially localized disease.
- Patients with newly diagnosed disease must have completed successful gross tumor resection for their primary tumor or surgical local control of primary tumor must be planned to be performed simultaneously with thoracic surgery.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
