Abstract

PURPOSE:

To evaluate the efficacy and the toxicity of front line FOLFOX4 combined with bevacizumab in patients with metastatsic CRC (mCRC).

PATIENTS AND METHODS:

Chemotherapy-naïve patients with mCRC, received bevacizumab (5 mg/kg every 2 weeks d1), oxaliplatin (85 mg/m2 on d1), leucovorin (200 mg/m2) on days 1 and 2 and 5-Fluorouracil (400 mg/m2 as i.v. bolus and 600 mg/m2 as 22 h i.v. continuous infusion on days 1 and 2) every 2 weeks.

RESULTS:

Fifty three patients (46 with a PS 0-1) were enrolled. Complete and partial response was achieved in eight (15.1%) and 28 (52.8%) patients, respectively (ORR: 67.9%; 95% C.I.: 53.8%-92%); 11 (20.7%) patients had stable disease and six (11.3%) progressive disease. With a median follow up period of 13.5 months, time to tumor progression was 11 months while the median survival has not yet been reached; the probability of 1-, 2- and 3- year survival was 79.8%, 63.8% and 58.3%, respectively; Two patients relapsed during the follow up period. Eight (15%) patients underwent metastasectomy with R0 resections. Grade 3-4 neutropenia occurred in 15.1% of patients and one (1.9%) of them presented febrile neutropenia. Non-hematologic toxicity included grade 3 diarrhea (7.6%) and grade 2 and 3 neurotoxicity in 16.9 and 15.1% of patients, respectively. One (1.9%) patient presented pulmonary embolism and one (1.9%) cardiac ischaemia. There was one (1.9%) sudden death after the first cycle.

CONCLUSION:

The combination of FOLFOX4/bevacizumab appears to be highly effective, well tolerated and merits further evaluation in patients with mCRC.
