title: [Continuous double administration of 5 fluorouracil (intravenous and intraperitoneal) modulated by folinic acid: phase I clinical study and pharmacokinetics in patients with intra-abdominal developing cancers].
abstract: Thirteen patients with intra-abdominal malignancies entered a phase I study of fluorouracil (5-FU) given by continuous infusion (96 h) iv and ip, simultaneously, and modulated by high-dose folinic acid-iv. Severe but reversible stomatitis was the only dose-limiting toxicity at a dose of 5-FU of 550 mg/m2/day. Local toxicity (5-FU-induced abdominal pain) was a significant side effect in patients receiving more than 1 cycle. The pharmacokinetic advantage of 5-FU-ip was confirmed in our study (ratio AUC peritoneum/plasma between 160 and 328). The systemic exposure to 5-FU (plasmatic AUC ranging from 73.4 to 173.21 microM) and to AF were found in efficacious ranges. The recommended dose of 5-FU iv and ip is 500 mg/m2/day. This regimen is feasible and may potentially have application for adjuvant chemotherapeutic programs after surgery for colorectal cancer.
