Outcome Measures

Primary Outcome Measures

Major Pathological Response Rate [Average 3 months (after resection of metastases)]
Major pathological response rate (MPRR) is defined as the proportion of patients presenting a major pathological response. Pathologic response will be evaluated according the Rubbia-Brandt Tumor Regression Grade classification .For patients with multiple colorectal metastases the global pathological response will be categorized based on the mean TRG of all metastases.: a major response is defined as a mean TRG < 3, a partial response is defined for patient presenting a mean TRG ≥3 and <4, and a no response for patient with a mean TRG ≥4.

Secondary Outcome Measures

progression free survival [at 6 months and at 12 months after randomization]
-Progression Free Survival (PFS) is defined as the time from randomization to the time of first event (relapse of the original mCRC, development of a new colorectal cancer or death due to any cause). Patients without any such event at the time of data analysis will be censored at the last date they were known to be event-free. PFS analysis will be based on tumour assessments and survival follow-up assessments.
Overall survival [At the end of the study]
The overall survival will be analyzed at the end of study (3 year of recruitment and one year of follow-up).
Clinical response rate [at time of surgery -]
Clinical response rate at time of surgery: Clinical tumour response will be measured according to the RECIST 1.1 criteria
Metabolic response rate [At time of surgery - average 3 months]
Metabolic response rate at time of surgery (in selected centres only, optional): Metabolic tumour response will be measured according to the EORTC criteria . PET-Scan evaluation remains optional to selected centres only.
post operative complications [one month after surgery]
. Severe pre- or postoperative complications within 30 days of surgery: surgery-associated bleeding requiring replacement with > 4 units of erythrocyte concentrates, wound infection, intra-abdominal infection, severe sepsis (American College of Chest physicians/Society of Critical Care Medicine, 1992), impaired wound healing, subphrenic or perihepatic abscess requiring drainage during hospital stay or within 30 days after the operation, re-laparotomy connected with the resection, a biliary fistula for more than 10 days with a discharge of > 100 mL/day, transient liver failure (bilirubin > 10 mg/dL lasting > 3 days), renal failure requiring dialysis, respiratory failure with renewed necessary mechanical ventilation, venous thromboembolism, cardiac failure, death of the patient as a result of the operation.
Curative resection rate [At time of surgery]
Curative resection rate (R0 resection) is defined by the surgical clearance (+/- radiofrequency ablation) of all detectable hepatic lesions with tumor-free margins at histo-pathological evaluation.
Chemotherapy-associated hepatotoxicity: [at time of surgery]
Systemic neo-adjuvant chemotherapy in mCRC frequently causes morphological lesions involving hepatic microvasculature . Sinusoidal obstruction, complicated by perisinusoidal fibrosis and veno-occlusive lesion of the non tumoral liver, should be included in the list of the adverse side-effects of colorectal systemic chemotherapy, in particular related to the use of oxaliplatin.

Eligibility Criteria

Criteria

Ages Eligible for Study:

18 Years and Older

Sexes Eligible for Study:

All

Accepts Healthy Volunteers:

Inclusion Criteria:

Female or male patients with at least 18 years at the time the informed consent is signed
ECOG performance status 0 or 1
Histological or cytological confirmed diagnostic of adenocarcinoma of the colon or rectum, with or without primary tumour in situ. Wild-type RAS and B-RAF tumor status.
Patients with potentially resectable metastatic disease at diagnosis and for whom a chemotherapy first in a curative intent is recommended . Resectability could be planed in one or multiple stage if indicated. As commonly admitted, resectability means the surgical clearance (+/- radiofrequency ablation) of all detectable (liver) lesions with tumor-free margins and compatible with an adequate hepatic reserve. Practically, bilateral tumor location, number and location of lesions, and inadequate hepatic reserve remain the main decisional factors.
Partial and minor resection of metastatic disease is allowed within 3 months before inclusion if patient has never received chemotherapy for mCRC.
Extra hepatic metastatic location is limited to 1 site.
Patients may have received adjuvant chemotherapy or (neo-) adjuvant chemo-radiotherapy to the pelvis, provided the last dose of chemotherapy was administered at least 6 months prior to inclusion (12 months for oxaliplatin). Previous radiotherapy to the pelvis is not an exclusion criterion.
Adequate haematological, renal and hepatic function as follows:

Haematological:

haemoglobin >9g/dl Neutrophils > 1.5 x 109/L Platelets > 100 x 109/L

Renal:

Creatinine< 1.5 x ULN (Upper Limit of Normal)

Hepatic:

Bilirubin < or equal 1.5 X ULN AST (Aspartate Aminotransferase),and ALT (Alanine Aminotransferase)< or equal 5 x ULN, Phos Alc< or equal 5 x ULN

Female patients must either be postmenopausal, sterile (surgically or radiation- or chemically-induced), or if sexually active using an acceptable method of contraception.
Male patients must be surgically sterile or if sexually active and having a pre-menopausal partner must be using an acceptable method of contraception.
Life expectancy of at least 3 months without any active treatment.

Exclusion Criteria:

1.Definitively non resectable mCRC at diagnosis
2.Prior chemotherapy or systemic therapy for mCRC. Adjuvant chemotherapy for colorectal cancer is not an exclusion criterion provided that it was completed more than 6 months prior to inclusion. Oxaliplatin-based chemotherapy must be completed more than 1 year prior to inclusion.
3.Prior utilization of cetuximab, panitumumab (or other anti-EGFR (epidermal growth factor receptor)therapy).
4.Previous radiotherapy delivered to the upper abdomen.
5 Non mesurable disease( RECIST 1.1 criteria)
6.Evidence of ascites, cirrhosis, portal hypertension, main portal venous tumour involvement or thrombosis as determined by clinical or radiologic assessment.
7.Prior major liver resection: remnant liver < 50% of the initial liver volume.
8.Non-malignant disease that would render the patient unsuitable for treatment according to this protocol.
9.Concurrent central nervous systems metastases
10.Peripheric neuropathy ≥ grade 2.
11.Interstitial lung disease
12.Pregnant or breast feeding.
13.The patient has previous or concomitant malignancies, except: Invasive malignancies in remission for more than 5 years and non melanoma skin cancer or carcinoma in situ of the cervix.
