Abstract

Background. Therapeutic efficacy of endoscopic photodynamic therapy (PDT) for advanced gastric cancer is limited. Recent animal studies have clarified the very important role of host immune cells in PDT. We expected a potential cooperative effect of PDT and immunotherapy, and developed immunotherapy-combined PDT (I-PDT) for advanced gastric cancer.

Methods and Materials. We applied I-PDT for two elderly patients with complicated advanced gastric cancer (92- and 89-yr-old males). Tumor bleeding prevented them from leading an ordinary home life. Initial simple PDT was not effective. Patients received over 109 activated T-lymphocyte-predominant autologous immune cells, mainly intravenously, 5× for one course. PDT was performed endoscopically on the day of the third infusion.

Results. Two or three courses of I-PDT safely stopped tumor bleeding, and the initial poor prognoses of a few months of survival seemed to be improved (patient 1, over 32 mo; patient 2, 14 mo).

Conclusions. I-PDT was found to be a safe, feasible treatment that could improve symptoms resulting from advanced gastric cancer.
