Detection method
Provided is a vital stain inspection method for distinguishing between cancer cells and normal cells within a lumen, or on the serous membrane side of an organ, by means of laser irradiation after organ tissue has been stained by curcumin, Red #3 or Red #106, which are edible color dyes.
1. A method for detecting cancer progression comprising staining an organ tissue suspected of having cancer with curcumin and then laser irradiating the organ tissue from serosal side or lumen using a multiphoton laser microscopic endoscope, confocal laser microscopic endoscope or laser fluorescent microscopic endoscope, and visualizing Meissner's plexus or Auerbach's plexus present in the organ tissue, wherein the organ tissue is digestive tract tissue, and a primary lesion is in mucosal epithelium.
2. The method according to claim 1 , wherein if cancer cells have invaded or reached Meissner's plexus, the cancer is an advanced cancer.
3. The method according to claim 1 , wherein if cancer cells have invaded or reached the Meissner's plexus and smooth muscle layer, the cancer is an advanced cancer.
4. The method according to claim 1 , wherein if cancer cells have not invaded or reached Meissner's plexus, the cancer is an early cancer.
5. The method according to claim 1 , which further comprises signaling the detection of cancer cells by sound or light.
6. A method of claim 1 for treating cancer patients comprising removing cancer cells one by one from serosal side or lumen.
7. A method of claim 1 for removing the cancer cells one-by-one, comprising confirming cancer cells remaining in a living body from serosal side or lumen after surgery.
8. A method according to claim 1 for treating colon cancer patients.
9. A method according to claim 1 for treating lung cancer patients.
10. A method according to claim 1 for treating prostate cancer patients.
11. A method according to claim 1 for treating gastric cancer patients.
12. A method according to claim 1 for treating esophageal cancer patients.
13. A method according to claim 1 for treating bladder cancer patients.
14. A method according to claim 1 for diagnosing advanced cancer, wherein the cancer is judged as an advanced cancer based on visualized images if the cancer cells have invaded or reached Meissner's plexus, or the cancer cells have invaded or reached Meissner's plexus and smooth muscle layer.
15. A method according to claim 1 for diagnosing early cancer, wherein the cancer is judged as an early cancer based on visualized images if the cancer cells have not invaded or reached Meissner's plexus.
16. A method according to claim 1 for treating patients with uterine cancer or ovarian cancer.
17. A method according to claim 1 for treating patients with breast cancer.
18. A method according to claim 1 for treating patients with pancreatic cancer or gallbladder cancer.
19. A method according to claim 1 for treating tongue cancer, throat cancer, laryngeal cancer, or thyroid cancer.
