Lattice Radiation Therapy Versus Conventional Radiation Therapy for the Palliation of Large Tumors
Sponsor: University Health Network, Toronto
Summary
The goal of this randomized, phase III trial is to to determine if Spatially Fractionated Lattice Radiotherapy (SFRT) known as LATTICE therapy, leads to a greater reduction in pain or discomfort compared with conventional Radiation Therapy (RT) in patients with large tumours. This is evaluated by assessing if a greater proportion of patients who receive RT with SFRT will have an improvement in pain/discomfort at 30 days defined using the International Consensus Pain Response (ICPR) compared with those treated with conventional RT.

Interventions
Conventional Radiation Therapy
Delivered using simple techniques and includes dose prescriptions of: 8Gy in 1 fraction, 20Gy in 5 fractions, and 30Gy in 10 fractions
Spatially fractionated radiation therapy
LRT delivers ablative doses to discrete vertices within a tumor, forming a "lattice" while restricting the periphery of the tumor to a safe, low dose thereby minimizing radiation exposure to nearby OAR.
