Study Description

Brief Summary

The purpose of this study is to to evaluate the correlation of overall objective response according to RECIST v1.1. criteria evaluated by conventional imaging techniques, morphologic response by CT, and histopathologic response in patients with resectable hepatic metastasis secondary to colorectal cancer treated with bevacizumab in combination with XELOX.

Outcome Measures

Primary Outcome Measures

1. Correlation of overall objective responses evaluated by conventional imaging techniques with the morphologic response evaluated by MDCT and the histopathologic response after the resection of hepatic metastases. [2016]

Secondary Outcome Measures

1. R0/R1/R2 resectability rate. [2016]

2. Progression-free survival (PFS), only in patients who do not undergo metastasis resection. [2016]

3. Recurrence-free survival (RFS) in patients who undergo metastasis resection. [2016]

4. Safety and toxicity (surgical and therapeutic) of the therapy graded according to CTC v.4.0 [2016]

5. Overall survival (OS) at 2 and 3 years. [2016]

6. Examine the influence of a potential predictive and prognostic tumour biomarker -mutations in K-RAS- after start of therapy on overall objective response [2016]

7. Examine the influence of a potential predictive and prognostic tumour biomarker -mutations in K-RAS- after start of therapy on surgical resection rate [2016]

8. Examine the influence of a potential predictive and prognostic tumour biomarker -mutations in K-RAS- after start of therapy on survival [2016]

9. Examine the influence of a potential predictive and prognostic tumour biomarker -mutations in K-RAS- after start of therapy on progression free survival [2016]

Patients with the diagnosis of liver metastasis presenting synchronically or after a disease-free interval. The primary tumor shall have been resected previously although the inverse approach may be acceptable if the tumor is not very symptomatic. Patients in whom combined surgery of the primary tumor and metastases is planned are not eligible.
