Abstract
Simple Summary
The association between photodynamic therapy (PDT) and mortality in lung cancer patients remains unclear. We studied the association between PDT and mortality in patients with stage III/IV non-small cell lung cancer (NSCLC) using the National Cancer Database (NCDB) between 2004 and 2016. From the NCDB, we identified patients whose treatment code was ablation (including PDT). From Medicare and Medicaid data between 2000 and 2013, we identified NSCLC patients receiving PDT and used these to confirm PDT treatment. We assessed the association between PDT and mortality. Study groups consisted of 147 patients with PDT + radiation + chemotherapy, 227,629 with radiation + chemotherapy, 106,667 with radiation therapy alone and 122,193 with chemotherapy alone. Compared to the radiation alone group, the PDT group and radiation with chemotherapy group had lower risk of mortality (50% and 53% lower, respectively). Among the NSCLC patients with stage III or stage IV disease not eligible for surgery, the addition of PDT to chemotherapy and radiation therapy offers survival benefit over radiation therapy alone.
Abstract
Data regarding the association between photodynamic therapy (PDT) and mortality in lung cancer patients are limited. We analyzed the association between PDT and mortality in patients with stage III or IV non-small cell lung cancer (NSCLC) using data from the National Cancer Database (NCDB) between 2004 and 2016. From the NCDB, we identified patients receiving laser ablation/cryosurgery or local tumor destruction/excision (which includes PDT). From Medicare and Medicaid claims between 2000 and 2013, we identified NSCLC patients receiving PDT and those receiving bronchoscopy, then used these to confirm the PDT treatment. From NCDB, we extracted NSCLC patients who received radiation with chemotherapy, radiation alone or chemotherapy alone. We used survival analysis to determine the association between PDT and mortality. Between 2004 and 2016, 457,556 NSCLC patients with stage III or stage IV were identified, of which 147 received PDT with radiation and chemotherapy, 227,629 received radiation with chemotherapy, 106,667 had radiation therapy alone and 122,193 received chemotherapy alone. Compared to the radiation alone group, the PDT group and radiation with chemotherapy group had lower hazard of mortality (50% and 53% lower, respectively). Among the NSCLC patients with stage III or stage IV disease, the addition of PDT to radiation therapy offers survival benefit over radiation therapy alone.
