Treatment And Outcomes For Early Non-Small-Cell Lung Cancer: A Retrospective Analysis Of A Portuguese Hospital Database

Aim: This observational study evaluated treatment patterns and survival for patients with stage I-IIIA non-small-cell lung cancer (NSCLC). Materials & methods: Adults newly diagnosed with NSCLC in 2012-2016 at IPO-Porto hospital were included. Treatment data were available for patients diagnosed in 2015-2016. Results: 495 patients were included (median age: 67 years). The most common treatments were surgery alone or with another therapy (stage I: 66%) and systemic anticancer therapy plus radiotherapy (stage II: 54%; stage IIIA: 59%). One-year OS (95% CI) for patients with stage I, II and IIIA NSCLC (diagnosed 2012-2016) were 92% (88-96), 71% (62-82) and 69% (63-75), respectively; one-year OS (95% CI) for treated patients with stage I-II or stage IIIA NSCLC (diagnosed 2015-2016) were 89% (81-97) and 86% (75-98) for non-squamous cell and 76% (60-95) and 49% (34-70) for squamous cell NSCLC. Conclusion: Treatment advances are strongly needed for stage I-IIIA NSCLC, especially for patients with squamous cell histology.
