[Study of pre-operative chemotherapeutic methods for colonic cancer--the concentration in blood and tissues after pre-operative administration of UFT].
As one of the fundamental studies of the pre-operative chemotherapeutic methods in 22 cases with colonic cancer, we studied a progress of the concentration in blood and concentration in tissues including those in the portal vein after administration of UFT. The concentration of 5-FU in blood reached to the peak at 2 hours after administration of UFT and then decreased rapidly, while it was maintained for a long term in comparing with that of 5-FU (oral remedies; tablet and dry syrup). This fact suggested that UFT can be expected for metastatic inhibition and prevention of the recurrence because it showed an effect in free-cancerous cells before and during operation. The anti-tumorous effect was also expected because the concentration of 5-FU in cancerous tissues was significantly higher than that in non-cancerous region. In our study in this time, down staging was considered by pre-operative chemotherapeutic method of colonic cancer in the future because concentration of 5-FU was also highly obtained in metastatic lymph nodes. From the above-mentioned results, pre-operative chemotherapeutic method using UFT was expected as a part of the intensive therapies.
