A Study of Radiation Therapy to Treat Solid Tumor Cancer That Has Spread to Soft Tissue

Inclusion Criteria:

Patients with biopsy confirmed advanced/metastatic solid tumors of the following types: invasive ductal or lobular breast carcinoma (all histological and intrinsic subtypes), non-small cell lung cancer (NSCLC, all subtypes), gastrointestinal squamous cell or adenocarcinomas (including pancreatic cancer), bladder cancer, renal cell carcinoma, melanoma, and sarcoma, who require palliative radiation therapy to at least one site of extracranial metastastic disease. If a patient, requires palliative radiotherapy to additional sites, these can be treated with standard of care SBRT per departmental guidelines.
Patients with at least one additional site of extracranial metastasis measuring at least 100 cc and suitable for elective palliative radiation therapy. Patients should be asymptomatic or minimally symptomatic (e.g controlled by oral pain medications) and not in urgent need for palliation to this site of elective treatment.
Age ≥ 18 years
ECOG Performance Status of 0 or 1.

Exclusion Criteria:

Patients who are pregnant or breastfeeding
Prior radiation therapy to the candidate metastatic sites under consideration for treatment ("re-irradiation" is disallowed).
Medical condition such as uncontrolled infection (including HIV), uncontrolled diabetes mellitus, or connective tissue diseases (lupus, systemic sclerosis, or other collagen vascular diseases) that, in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient.
Patients with a "currently active" metastatic second malignancy.
Patients on oral or parental corticosteroids
Concomitant anti-neoplastic treatment is not allowed during the days of radiation treatment delivery and should be completed or held for 3 days prior to commencement of protocol treatment and for 3 days following completion of radiotherapy, or with resolution of associated acute toxicities.
Unwilling or unable to participate in all required study evaluations and procedures.
Unable to understand the purpose and risks of the study and to provide a signed and dated informed consent form (ICF) and authorization to use protected health information (in accordance with national and local patient privacy regulations).
