Abstract

Background Oxaliplatin, 5-fluorouracil (5-FU), and leucovorin (LV) are standard first-line treatments for patients with metastatic colorectal cancer (mCRC). The aim of this multicentre, open-label, phase IIIb study was to assess the addition of oxaliplatin to two different 5-FU regimens.Patients and methods Patients with previously untreated mCRC were randomised to arm A [two-weekly oxaliplatin 85 mg/m(2) + either continuous intravenous infusion (CIV) of 5-FU without LV or two-weekly bolus and CIV 5-FU + LV (LV5FU2)] or arm B (5-FU CIV or LV5FU2 alone). Irinotecan monotherapy was planned on progression.Results A total of 725 patients were enrolled. After a fixed follow-up of 2 years for each patient, 2-year survival rates were 27.3% and 24.8% in arms A and B, respectively (hazard ratio 0.93; 95% confidence interval 0.78-1.10). The addition of oxaliplatin significantly improved response rates (54.1 versus 29.8%; P < 0.0001) and median progression-free survival (7.9 versus 5.9 months; P < 0.0001). The most common grade 3-4 toxic effects were neutropenia (arm A, 33%; arm B, 5%), diarrhoea (arm A, 14%; arm B, 8%), and fatigue (arm A, 9%; arm B, 8%).Conclusions Despite improved rates of tumour control, these results failed to demonstrate a survival benefit from the addition of oxaliplatin to infused 5-FU and lend further support to the use of sequential monotherapy in some patients with mCRC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
