title: [Clinical study of serum and tissue concentrations of FT-207 and 5-FU in patients with cancer of the large intestine following preoperative application of FT-207 suppositories].
abstract: 1.5 g/day of FT-207 suppository was administered for two weeks prior to operation to twenty patients with large bowel carcinoma of familiar poliposis coli. The level of FT-207 and 5-FU in serum, lymph node, tumor and normal colonic mucosa were determined by bioassay. The levels of FT-207 in the rectum, sigmoid colon and tumor were higher than that in serum. The levels of 5-FU in the rectum, sigmoid colon, tumor and lymph node were also higher than that in serum. The levels of FT-207 and 5-FU in carcinoma of the rectum was higher than those in serum. Compared with the level in normal rectal mucosa, only the level of 5-FU in rectal carcinoma was higher. From the histological point of view, the highest levels of FT-207 and 5-FU was observed in well-differentiated adenocarcinoma. There was no side effect experienced in our series, therefore, FT-207 suppository seems to be one of the safe promising preoperative chemotherapies.
