[Toxicity of levamisole in adjuvant chemotherapy for colorectal cancer]. / Toxicité du lévamisole dans la chimiothérapie adjuvante du cancer colorectal.

We studied the levamisole toxic effects in adjuvant therapy for colorectal cancer. The therapy toxic effects on 127 patients were statistically more important in the levamisole-treated group compared to patients treated with folinic acid and 5-fluorouracil alone. Randomized studies in progress will demonstrate the real therapeutic value of levamisole.
