Intraoperative photodynamic therapy in surgical treatment of gastric cancer (literature review)

Gastric cancer is one of the most common cancer type and the 2-nd leading cause of death among all malignances (13,1%). Long-term results after conditionally-radical surgeries for locally advanced gastric cancer remain poor. Despite advances in surgical techniques, peritoneal dissemination remains a major complication of gastric cancer. Considering the mechanisms of developing peritoneal dissemination, the search for the new effective treatment approaches with the aim to reduce the risk of development of peritoneal carcinomatosis, to raise the ablastics of the resections and to prolong the disease-free period is of great importance for patients with locally advanced and disseminated gastric cancer. The analysis of literature data on a new technique of intraoperative photodynamic therapy has been presented.
