Pancreatic cancer is an extremely malignant disease with high mortality rate. Currently there is no effective therapeutic strategy for highly metastatic pancreatic cancers. Laser immunotherapy (LIT) is a combination therapeutic approach of targeted phototherapy and immunotherapy, which could destroy treated primary tumors with elimination of untreated metastases. Here, we investigate the antitumor immune response of LIT on a highly aggressive phenotype Pnac02-H7 mouse pancreatic tumor model. LIT affords a remarkable efficacy in suppressing tumor growth in pancreatic tumors in mice, and results in complete tumor regression in many cases. LIT could synergize targeted phototherapy and immunological effects of immunoadjuvant, which represent a promising treatment modality to induce systemic antitumor response through a local intervention, paving the way for the treatment of highly metastatic pancreatic cancers.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
