Stage IV NSCLC That Worsens during Chemo Could Be Treated with Erlotinib and SBRT

The gist: Stage IV non-small cell lung cancer (NSCLC) patients whose cancer worsened during platinum-based chemotherapy might benefit from treatment with the drug erlotinib and stereotactic body radiation (SBRT) therapy.

“Treatment with stereotactic body radiation therapy and erlotinib appeared highly effective in patients with metastatic stage IV non–small cell lung cancer who progressed on prior platinum-based chemotherapy, according to results of a single-arm phase 2 study.

“Patients with stage IV NSCLC who progress on first-line chemotherapy historically demonstrate poor survival outcomes, and they typically fail in original sites of gross disease, according to background information provided by researchers.

“Puneeth Iyengar, MD, PhD, assistant professor of radiation oncology at UT Southwestern Medical Center, and colleagues hypothesized that stereotactic body radiation therapy (SBRT) may help systemic agents delay relapse.

“Iyengar and colleagues evaluated PFS, OS and other outcomes among 24 patients (median age, 67 years) who underwent second- or later-line treatment with SBRT plus erlotinib (Tarceva; Genentech, Astellas).”
