Brief Summary
The clinical benefit of resection of the primary tumour in patients with synchronous unresectable metastases is not known. In the literature studies usually describe retrospective selected patients with synchronous metastases treated with or without resection of the primary tumour. All these studies are biased in patient selection and there are no prospective randomized studies on this topic. In patients with few or absent symptoms of the primary tumour, arguments both in favour and against initial resection have been presented, and therefore a randomized trial is warranted. Although recent publications suggest that resection of the primary tumour in synchronous metastasized colon cancer patients might not be necessary, this appears to be based on feasibility and not on clinical outcome. Several studies comparing large groups of patients with or without resection of the primary tumour suggest an improved survival when the primary tumour is resected. A potential benefit of resection of the primary tumour is to prevent complications of the primary tumour during chemotherapy treatment or during later stages of the disease. A recent analysis of the CAIRO and CAIRO2 data showed that metastatic colon cancer patients who had a resection of the primary tumour prior to study entry, had an improved survival compared to patients without a resection of the primary tumour. However, these patients were selected after the primary tumour was resected and therefore these results are not corrected for surgical morbidity and mortality. The investigators here propose a randomized trial in order to demonstrate that resection of the primary tumour does improve overall survival.

Outcome Measures
Primary Outcomes (1)
Overall survival
Overall survival of the intent-to-treat population
Time from randomisation until death, assessed up to 5 years
Secondary Outcomes (9)
Progression-free survival
Time from randomisation until first progression or death whichever comes first, asessed up to 5 years
Response to chemotherapy
Fist-line chemotherapy, assessed until progression
Systemic therapy related toxicity
Every 3 weeks during first-line treatment
Surgery related morbidity and mortality
30 days
Quality of life
Every 6 months from randomisation until first progression
- +4 more secondary outcomes
Study Arms (2)
Systemic treatment
ACTIVE COMPARATORFirst-line fluoropyrimidine-based chemotherapy with bevacizumab initiated within 4 weeks of randomization, followed by salvage therapy upon progression at the discretion of the local investigator. Surgery of primary tumour will be performed only when indicated by local signs or symptoms.
Surgery followed by systemic treatment
EXPERIMENTALSurgery within 4 weeks of randomization followed by fluoropyrimidine-based chemotherapy with bevacizumab until progression or unacceptable toxicity, followed by salvage therapy upon progression at the discretion of the local investigator
Interventions
Surgical resection of the colon tumour
First line fluoropyrimidine-based chemotherapy with bevacizumab. The chemotherapy regimen is to the discretion of the local investigator, who may choose between: 5FU/LV or capecitabine or capecitabine + oxaliplatin(CAPOX)or 5FU + oxaliplatin(FOLFOX 4 or FOLFOX 7)or 5FU + irinotecan (FOLFIRI) or capecitabine + irinotecan(CAPIRI)
Eligibility Criteria
You may qualify if:
- Histological proof of colorectal cancer
- Resectable primary tumour in situ with unresectable distant metastases
- No indication for neo-adjuvant (chemo)radiation
- No severe signs or symptoms related to the primary tumour (i.e. severe bleeding, obstruction, severe abdominal pain) that require immediate surgery or other symptomatic treatment (e.g. stenting)
- No prior systemic treatment for advanced disease
- Age ≥ 18 years
- WHO performance status 0-2
- Laboratory values obtained ≤ 4 weeks prior to randomization: Adequate bone marrow function (Hb ≥ 6.0 mmol/L, absolute neutrophil count ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L), renal function (serum creatinine ≤ 1.5x ULN and creatinine clearance, Cockroft formula, ≥ 30 ml/min), liver function (serum bilirubin ≤ 2 x ULN, serum transaminases ≤ 3 x ULN without presence of liver metastases or ≤ 5x ULN with presence of liver metastases)
- Expected adequacy of follow-up
- Written informed consent
- CT scan abdomen and CT thorax/X-thorax performed ≤ 4 weeks prior to randomization
You may not qualify if:
- Pregnancy, lactation
- Unresectable primary tumour (i.e. neurovascular encasement, substantial ingrowth in pancreatic head), or any condition preventing the safety or feasibility of resection of the primary tumour, i.e. massive ascites or extensive peritoneal disease
- Requirement of neoadjuvant (chmo)radiation therapy
- Second primary malignancy within the past 5 years with the exception of adequately treated in situ carcinoma of any organ or basal cell carcinoma of the skin
- Any medical condition that prevents the safe administration of systemic treatment
- Previous intolerance of fluoropyrimidines, known dihydropyrimidine dehydrogenase (DPD) deficiency
- Planned radical resection of all metastatic disease
- Uncontrolled hypertension, i.e. values consistently \> 150/100 mmHg
- Use of ≥ 3 antihypertensive drugs
- Significant cardiovascular disease \< 1 yr before randomization (symptomatic congestive heart failure, myocardial infarction, unstable angina pectoris, serious uncontrolled cardiac arrhythmia, cerebro vascular event)
- Chronic active infection
- Concurrent treatment with any other anti-cancer therapy as described per protocol
