Photodynamic therapy using nanoparticle loaded with indocyanine green for experimental peritoneal dissemination of gastric cancer.
Bottom Line: Forty-eight hours after injection of the photosensitizer, in vivo and ex vivo imaging was carried out.The PDT reduced the total weight of the disseminated nodules and significantly improved weight loss and survival rate in ICGm-treated mice.In conclusion, ICGm can be used as a novel diagnostic and therapeutic nanodevice in peritoneal dissemination of gastric cancer.

Mentions: Although the overall body weight of ICG-treated mice gradually decreased throughout the investigation period, this weight loss was not observed in ICGm-treated mice (Fig. 4). The weight of the total disseminated nodules in ICGm-treated mice was significantly lower than that of ICG-treated mice, and there were fewer disseminated nodules in ICGm-treated mice than in ICG-treated mice (Fig. 5). Photodynamic therapy using ICGm significantly improved survival rate compared to that using ICG (log–rank, P < 0.05); the median survival time of ICGm-treated mice after PDT was 32 days (n = 8) and that of ICG-treated mice was 17 days after PDT (n = 8) (Fig. 6).
