Abstract

OBJECTIVE: We designed this trial to investigate if modifications in levels of circulating vascular endothelial growth factor (VEGF) may be related to clinical response and outcome in advanced colorectal cancer patients during treatment with a weekly combination of cetuximab plus irinotecan. METHODS: A total of 45 heavily pretreated metastatic colorectal cancer patients were prospectively evaluated for circulating levels of VEGF during the treatment with cetuximab plus weekly irinotecan. VEGF circulating levels were assessed at the following time points: just before and at 1, 21, 50 and 92 days after the start of cetuximab plus irinotecan treatment. RESULTS: Basal VEGF median levels were significantly decreased just 1 day after the first anticancer infusion (p = 0.016) and reached the highest statistical significance 92 days after the first infusion (p < 0.0001). A total of 22 patients showed a reduction in median VEGF circulating levels of at least 50% 92 days after the first infusion with respect to the basal time point. For patients with at least a 50% reduction in VEGF levels, the response rate was 45.5% compared with 8.7% in the nonreduced VEGF group (p = 0.014). The median time to progression was 6 months in the reduced VEGF group versus 3.9 months in the other patients (p < 0.0001). In addition, overall survival was longer in patients with VEGF reduction (11.0 months) than in patients without (9.6 months; p = 0.01). CONCLUSION: These data represent the first evidence that suggests a role of VEGF reduction in the prediction of efficacy of treatment with cetuximab plus weekly irinotecan in heavily pretreated advanced colorectal cancer patients.

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.
