dc.description.abstractBackground: The goal of lung cancer surgery is a complete tumor resection (R0 resection) with clear margins. 4% to 5% of resections have microscopic residual disease associated with worse prognosis. Definitive management is resection of residual tumor, which may not be tolerated by many patients, and definitive management is not well studied in these patients. We treated patients with stage I cancer and bronchial mucosal residual disease (MRD) with bronchoscopic photodynamic therapy (PDT). Methods: All patients who underwent definitive surgery for early-stage lung cancer were reviewed. Patients with R1 resection, stage I disease with MRD and or carcinoma in situ along the stump site were treated with bronchoscopic PDT. Patient characteristics, histology, type and site of surgery, pattern of recurrence, recurrence status, adverse events, and survival data were evaluated. Results: Eleven patients with bronchial mucosal R1 resection were treated with PDT along the stump site. The median age was 67. Three patients had carcinoma in situ and 8 had MRD. One patient (9%) had local recurrence 1 year after PDT treatment and was treated with radiation. Four patients (36%) had no evidence of recurrence to date after a median follow-up of 4 years and the other 6 patients had evidence of regional (16%) or distant (39%) recurrence. The local control rate was 91%. One patient developed pneumonia and other had photosensitivity reaction. Conclusion: Bronchoscopic PDT is safe and effective in selected group of patients with non-small cell lung cancer who have MRD along the stump site.es
