| Outline of Final Research Achievements |
This study was conducted to establish N1,N12-diacetylspermine (DiAcSpm) as a useful tumor marker, and to develop a simple and rapid procedure for DiAcSpm determination. Our study revealed that DiAcSpm was increased in early cancer tissues, and that this increase is responsible for the increased excretion of DiAcSpm in the urine of patients with early colorectal cancer patients. Further study indicated that preoperative urinary DiAcSpm level was significantly related with the risk of early recurrence of completely resected colorectal cancer and non-small cell lung cancer patients. We also developed an
immunochromatographic device for simple and rapid determination of urinary DiAcSpm. The simplicity of the procedure is a definite merit in promoting wider use of urinary DiAcSpm testing, a non-invasive and sensitive measure for early cancers.
