Abstract

Peritoneal metastasis is an important prognostic factor for pancreatic cancer. The present study evaluated the possibility of diagnosing peritoneal metastasis by a photodynamic diagnosis using 5‑aminolevulinic acid (5‑ALA‑PDD). In vitro, protoporphyrin IX (PpIX) accumulation was examined in the AsPC‑1‑GFP cell line following 5‑ALA hydrochloride administration. In vivo, AsPC‑1‑GFP cells were injected into the peritoneal cavities of mice. Three weeks later 5‑ALA hydrochloride was intraperitoneally administered to the mice. The peritoneal nodules were observed under fluorescence excitation. A total of 34 patients were enrolled in the present study who were clinically diagnosed with pancreatic malignancy. 5‑ALA hydrochloride was orally administered to the patients prior to surgery. During the operation the abdominal cavity was observed under white light and fluorescence. In vitro and in vivo, it was confirmed that PpIX‑induced red fluorescence. In 9 patients peritoneal nodules suspected to be peritoneal metastasis were observed under white light. In 4 of the 9 patients nodules were detected on the basis of the fluorescence images. Fluorescent nodules were histopathologically diagnosed as metastatic. In the present study it was confirmed that 5‑ALA‑PDD holds promise for the rapid diagnosis of peritoneal metastasis in patients with pancreatic cancer.
