Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialImportance of 5-fluorouracil dose-intensity in a double randomised trial on adjuvant portal and systemic chemotherapy for Dukes B2 and C colorectal cancer.
366 patients fully resected from a Dukes B2 or C colorectal cancer were randomised to receive 6 courses of systemic chemotherapy comprising either 5-fluorouracil (5 FU) alone (arm A: 450 mg/m2/day-5/21 days) or combined folinic acid (FOL) and 5 FU (arm B: respectively 200 mg/m2 racemic form or 100 mg/m2-l-form and 370 mg/m2/day-5/21 days). 173 patients had also been initially randomised to receive one course of intraportal chemotherapy just after surgery or no portal treatment. Oral levamisole (150 mg/day; 3 days every other week) was given to all patients for one year. A significantly higher incidence of leuco-granulocytopenia was observed in the arm A (5 FU alone) inducing more frequent dose delays and adaptations as well as levamisole's withdrawal. ⋯ The results are discussed in the light of other recent adjuvant trials. Well dosed 5 FU over a short period of time without folinic acid may be a valuable and inexpensive adjuvant treatment for colorectal cancer. Levamisole may no longer be recommended in this setting.

Randomized Controlled Trial Multicenter Study Clinical TrialRandomized controlled trial of 5-fluorouracil (5-FU) infusion combined with 1-hexylcarbamoyl-5-fluorouracil (HCFU) oral administration and HCFU alone as postoperative adjuvant chemotherapy for colorectal cancer.
Although surgical resectability is an important prognostic factor, recurrences are commonly noted in advanced colorectal cancer patients, even after apparently curative surgery. Because such recurrences cannot be cured, better adjuvant chemotherapies are urgently required. ⋯ Inductive therapy with 5-FU in combination with oral HCFU is beneficial as adjuvant chemotherapy for advanced colorectal cancer with lymph node metastasis.

Multicenter Study Clinical Trial Controlled Clinical TrialCombined irinotecan, docetaxel and conventionally fractionated radiotherapy in locally advanced head and neck cancer. A phase I dose escalation study.
Both docetaxel and irinotecan have shown strong radiosensitizing properties in vitro. Encouraging results have been reported by phase I/II studies on combined docetaxel or irinotecan with radiotherapy. In the present study we investigated the feasibility of double radiosensitization with weekly docetaxel and irinotecan in head and neck cancer. ⋯ Of interest, the lowest CR rate was observed in the 3rd dose level (2/4; 50%), which may be a consequence of overall treatment time prolongation. It is concluded that docetaxel and irinotecan combination with radiotherapy is feasible and, a high CR rate can be expected. Combination of the regimen with cytoprotective agents warrant further investigation.
