Favorable and unfavorable outcomes in patients in the PDT alone and PDT with surgery

	PDT alone	PDT with surgery
Favorable outcome	It takes less time so no anesthesia is needed. Less invasive to the body bronchial lumen and less likely to bleed.	The tumor tissue in the lumen was surgical resected first to reduce tumor load, and then laser irradiation was used to increase the degree of tumor necrosis and apoptosis. Less likely to relapse than PDT alone and is more effective than PDT alone.
Unfavorable outcome	PDT alone is only limited to tumor tissues without bulge in the lumen, that is, diffuse invasion and unresectable tumor tissues.	It takes a long time and the patient needs general anesthesia. During the resection of the tumor, it is very prone to bleeding and even perforation
