Background and Objectives: Incorporation of photodynamic therapy (PDT) into the induction therapy regimen utilized for treatment of locally advanced primary non-small cell bronchogenic carcinoma (NSCLC) is explored. Study Design/Materials and Methods: We present a retrospective review of 41 patients diagnosed with nonmetastatic NSCLC who underwent induction PDT with chemotherapy and/or radiation. Results: Fifty percent of patients initially deemed unresectable, were able to undergo definitive surgical resection after trimodality induction therapy. Twenty-seven percent of patients considered to require pneumonectomy were able to have a lobectomy. The pathological stage was less than the preinduction clinical stage in 14 of 22 cases; of which four patients had no residual tumor. There was no 30/90-day postoperative mortality. Mean survival was 35.9 months (lobectomy), 25.5 months (pneumonectomy) and 14.7 months (no surgery). Median survival was 78% (12 months) and 46% (36 months). The main postoperative complication following pneumonectomy was broncho-pleural fistula formation. All patients who developed this complication had undergone trimodality induction therapy. Incorporation of PDT into the induction arsenal for patients with loco-regionally advanced NSCLC may be safely performed. Conclusions: PDT may define an alternative induction strategy for patients requiring pneumonectomy; further studies exploring the true efficacy of PDT as an induction modality are encouraged.
