About this trial
The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
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 soft tissue sarcoma (all subtypes), who require and are being planned for palliative radiation therapy to at least one site of extracranial metastatic disease measuring at least 5 cm in a single axis. If a patient, requires palliative radiotherapy to additional sites, these can be treated with standard of care SBRT per departmental guidelines.
Age ≥ 18 years
ECOG Performance Status of 0 or 1.
Disqualifiers
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.

Trial outcomes
Primary outcomes
Overall Response Rate (ORR)
The primary endpoint is ORR in the LRT-treated lesion, as defined by RECIST v.1.1 criteria, at 12 weeks on a standard-of-care response assessment CT or F-18-FDG PET/CT scan after LRT.
