Primaire uitkomstmaten
To identify biological effects of bevacizumab therapy and to visualize distribution kinetics and uptake of 111In-bevacizumab in the micro-environment of the tumor with gamma-camera imaging.
Achtergrond van het onderzoek
Observational study evaluating the anti-angiogenic and apoptotic response of bevacizumab in patients with surgically resectable melanoma.
Patients with surgically resectable melanoma, who are planned for surgery will be treated neo-adjuvant with bevacizumab therapy. The anti-angiogenic and apoptotic response will be evaluated by measuring hematological and histological parameters. The distribution kinetics of 111In-bevacizumab will be visualized by gamma-camera imaging. The patients will receive two injections of 111In-bevacizumab and four gamma-camera scans. The first 2 scans will serve as a baseline. After the second scans it will be possible to compare imaging data before and after treatment and hereby evaluate tumor response.
Doel van het onderzoek
To identify biological effects of bevacizumab and to visualize distribution kinetics of 111In-bevacizumab with gamma-camera imaging.
Onderzoeksopzet
VEGF-SPECT imaging at baseline and 2 weeks following bevacizumab treatment prior to surgical resection.
Onderzoeksproduct en/of interventie
1. Adminstration of 7.5 mg/kg bevacizumab;
2. VEGF-SPECT imaging.
