Locally Advanced NSCLC Hyperfractionated RT
Completed · Phase 2
Conditions studied: Carcinoma, Non Small Cell Lung (NSCLC)
In brief
This is a prospective phase II study designed to evaluate an accelerated and adaptive RT approach for locally-advanced non-small cell lung cancer (NSCLC). All eligible subjects will have an interim PET-CT during radiation therapy to determine the metabolic complete response rate. Radiation therapy will be given in an accelerated fashion (2 Gy/fraction, 6 fractions/week) with concurrent chemotherapy. Interim responses will be assessed using PERCIST criteria. Despite concurrent chemotherapy and radiation therapy, local/regional failure occurs in \~50% of patients with locally-advanced NSCLC. Clinical studies have demonstrated that accelerated fractionation (giving the same total dose in a shorter period of time) improves outcomes in several malignancies, including lung cancer. Administering higher than conventional doses of RT to all sites of original disease leads to inferior outcomes. Adapting the RT approach, giving a higher dose to slowly responding disease as assessed with interim PET has been shown to be feasible. PERCIST (Positron Emission Tomography Response Criteria in Solid Tumors) provides guidelines on how to report responses to therapy based on PET-CT. PET-CT response has been shown to be prognostic in a variety of clinical scenarios in lung cancer including after induction therapy. In one study, PET was performed after neoadjuvant chemoradiotherapy (40-50.4 Gy). Complete or partial metabolic response using PERCIST criteria was predictive of loco-regional, distant, and overall progression-free survival.
