Modified pharmacokinetic modulating chemotherapy using 5-fluorouracil, UFT, and taxotere (docetaxel) for advanced gastric cancer.
The efficacy of neoadjuvant chemotherapy for advanced gastric carcinoma is controversial. Moreover, a standard regimen for such chemotherapy has not been clearly established. Pharmacokinetic modulating chemotherapy (PMC), a combination of infused 5-fluorouracil and oral uracil-tegafur, has been proven to be highly effective for the treatment of colorectal carcinoma. We report two patients with advanced gastric carcinoma successfully treated with PMC and infused taxotere (TXT; docetaxel). Preoperative treatment with PMC and TXT significantly decreased the depth of wall penetration of the tumor in one patient and reduced the size of the tumor in the other patient. In both patients, there were significant chemotherapeutic effects on the primary tumor and on regional lymph nodes pathologically. Preoperative PMC plus TXT produced primary tumor downstaging, leading to improved resectability. The responsiveness of metastatic cancer cells in the regional lymph nodes suggested the possibility of nodal downstaging by this regimen.
