Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In patients with a limited oligometastatic burden (cancer has spread but is not yet considered metastatic), emerging evidence suggests that treatment of all sites of disease with ablative therapies can improve patient outcomes, including overall- and progression-free survival. The application of Stereotactic Ablative Radiotherapy (SABR) for patients with 4-10 metastatic deposits appears promising, yet it is unclear if all patients with greater than 3 oligometastatic lesions benefit from ablative therapies in terms of improved Overall Survival (OS), Progression Free Survival (PFS), or quality of life. The purpose of this study is to assess the impact of SABR, compared to standard of care treatment, on overall survival, oncologic outcomes, and quality of life in patients with a controlled primary tumor and 4-10 metastatic lesions.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard arm

Standard of care treatment: palliative radiotherapy, chemotherapy, immunotherapy, hormones, or observation, is at the discretion of the treating oncologist.

Group Type ACTIVE_COMPARATOR

Palliative Radiation

Intervention Type RADIATION

Investigators should follow the principles of palliative radiotherapy as per the individual institution in order to alleviate symptoms or prevent complications. If radiotherapy is indicated, recommended doses are 8 Gy in 1 fraction, 20 Gy in 5 fractions, and 30 Gy in 10 fractions.

Chemotherapy

Intervention Type DRUG

Chemotherapy may be given as indicated.

Immunotherapy

Intervention Type DRUG

Immunotherapy may be given as indicated.

Hormones

Intervention Type DRUG

Hormones may be given as indicated.

Observation

Intervention Type OTHER

Observation only is acceptable if this is the standard practice.

Stereotactic Arm

Stereotactic ablative radiotherapy, plus standard of care treatment: chemotherapy, immunotherapy, hormones, or observation given at the discretion of the treating oncologist.

Group Type EXPERIMENTAL

Chemotherapy

Intervention Type DRUG

Chemotherapy may be given as indicated.

Immunotherapy

Intervention Type DRUG

Immunotherapy may be given as indicated.

Hormones

Intervention Type DRUG

Hormones may be given as indicated.

Observation

Intervention Type OTHER

Observation only is acceptable if this is the standard practice.

Stereotactic Ablative Radiotherapy

Intervention Type RADIATION

Total dose of radiation and number of fractions will depend on the site of disease. Doses are 20 Gy in 1 fraction, 30 Gy in 3 fractions (every 2 days), or 35 Gy in 5 fractions (daily).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age 18 or older
* Willing to provide informed consent
* Karnofsky performance score greater than 60
* Life expectancy greater than 6 months
* Histologically confirmed malignancy with metastatic disease detected on imaging. Biopsy of metastasis is preferred, but not required.
* Controlled primary tumor defined as: at least 3 months since original tumor treated definitively, with no progression at primary site
* Total number of metastases 4-10
* All sites of disease can be safely treated based on a pre-plan

Exclusion Criteria

* Serious medical comorbidities precluding radiotherapy. These include interstitial lung disease in patients requiring thoracic radiation, Crohn's disease in patients where the GI tract will receive radiotherapy, and connective tissue disorders such as lupus or scleroderma.
* For patients with liver metastases, moderate/severe liver dysfunction (Child Pugh B or C)
* Substantial overlap with a previously treated radiation volume. Prior radiotherapy in general is allowed, as long as the composite plan meets dose constraints herein. For patients treated with radiation previously, biological effective dose calculations should be used to equate previous doses to the tolerance doses listed below. All such cases must be discussed with one of the study PIs.
* Malignant pleural effusion
* Inability to treat all sites of disease
* Any single metastasis greater than 5 cm in size.
* Any brain metastasis greater than 3 cm in size or a total volume of brain metastases greater than 30 cc.
* Metastasis in the brainstem
* Clinical or radiologic evidence of spinal cord compression
* Dominant brain metastasis requiring surgical decompression
* Metastatic disease that invades any of the following: GI tract (including esophagus, stomach, small or large bowel), mesenteric lymph nodes, or skin
* Pregnant or lactating women
