| Research Abstract |
In Japan, gastric cancer is one of the most popular diseases. Although the relation between gastric cancer and H. pylori has been revealed, many patients have been dying. In photodynamic therapy using aminolevulinic acid, gastric cancer area can be diagnosed with cancer specific porphyrin fluorescence. Because of the difference between cancer patients and health persons in heme biosynthesis. Since these cancer specific porphyrins should be exclude out via urine and/ or feces, urinal porphyrins can be thereby a clue to diagnose cancer patients. To elucidate this possibility, we examine the urine from gastric cancer patients and healthy volunteers. Uroporphyrin I and III in cancer patients' urine showed the tendency to be bigger in comparison with them in healty volunteers, but no statistically significant difference.
The analysis with lager amount of patients probably shows the importance of this screening.
