SESSION TITLE: Lung Cancer II
SESSION TYPE: Original Investigation Poster

PURPOSE: We sought to analyze time to follow-up and sequence of treatment in non-small cell lung cancer (NSCLC) patients treated with photodynamic therapy (PDT) or non-PDT ablation therapy.
METHODS: Retrospective cohort analysis using SEER-Medicare linked data. Patients with NSCLC diagnosed between 2000 and 2011were identified and retrospectively followed for one-year pre and up to ten-year post diagnosis. We analyzed the proportion of treatment that occurred during phases of care and sequence of PDT treatment. Primary outcome was time to follow-up surgery or radiation therapy after PDT or non-PDT ablation therapy. Patients who did not initiate follow-up treatment of surgery or radiation were censored. Time to treatment, variation in health service use and cost were compared between PDT and non-PDT ablation groups. We used GLM models to assess time to follow-up treatment and costs in follow-up period. Propensity score approach was used to minimize selection bias.
