Details and patient eligibility


This is a prospective randomized phase II trial was done in clinical oncology department at Kasr Alainy hospital, Cairo university (NEMROCK) to evaluate the role of intensification of chemotherapy in the first line for treatment of metastatic colorectal carcinoma by adding third agent to standard doublet regimen on oncological outcomes \& assess tolerance to the intensified treatment

Full description

Patients with histologically proven adenocarcinoma of the colon or rectum, with unresectable measurable metastatic disease, were enrolled and randomized in a 1:1 ratio. Patients were assigned to receive FOLFOXIRI (experimental arm) or FOLFIRI or FOLFOX4 (control arm) biweekly up to 12 cycles. Randomization was done by enclosed envelope method Evaluation of the patients for surgical resection of residual metastases was done every 12 weeks. In the case of secondary resection of metastases, patients completed with the same chemotherapy regimen received before resection up to 12 cycles Maintenance therapy with capecitabine for 6 months was administered for patients who achieved complete or partial tumor response. In case of disease progression, second line chemotherapy was then administered in both groups until tumor progression, the occurrence of an unacceptable adverse event, or patient refusal


64 patients




18 to 60 years old

standard duplet regimen (FOLFOX or FOLFIRI)
Active Comparator group
Regimen consisted of 180 mg/m² intravenous infusion of irinotecan for 60 min OR 85 mg/m² oxaliplatin day 1 only followed by a 200 mg/m² intra venous infusion of leucovorin for 120 min, a 400 mg/m² intravenous bolus of fluorouracil, and a 600 mg/m² continuous infusion of fluorouracil for 22 hr to be repeated on day 2
