Gustavo Viani: High single dose SRS is promising in oligometastatic cancer

Gustavo Viani posted on LinkedIn:

DESTROY-2 trial shows that High single dose SRS is promising with good local control and minimal toxicity in oligometastatic cancer!!

Objective:
To report final outcomes of the DESTROY-2 trial, a phase I study assessing stereotactic radiosurgery (SRS) in treating or metastatic tumors in extracranial sites

Methods:

• Study Design: Prospective dose-escalation study in with oligometastatic cancer (1–5 lesions)
• Endpoint: Define the maximum tolerated dose (MTD) of SRS-VMAT
• Objectives: Evaluate safety, efficacy, and long-term outcomes
• Treatment: Single high-dose SRS-VMAT administered to 227 lesions in 164 across, liver, and other extracranial sites

Results:

• Dose Levels Achieved: 34 Gy for, 32 Gy for liver, 24 Gy for, and 24 Gy for other sites
• Toxicity: Minimal acute toxicity (16.5% grade 1-2, one grade 3); rare late toxicity events
• Response Rate: 94.5% overall response; progression 5.5% of cases
• Survival Rates: 2-year local control at 81.7%, overall survival at 78.7%.”
