Abstract

The management of patients with non-progressive metastatic colorectal cancer after six months of treatment has not yet been codified. The most relevant concerns are the effectiveness of maintenance vs discontinuation, and the tolerability of prolonged treatment. Here we report the case of a 72-year-old man affected by colorectal cancer with lung metastases who achieved a complete response after receiving capecitabine, oxaliplatin and bevacizumab for six months, and bevacizumab alone for six months. Bevacizumab was continued as maintenance regimen for more than three years. It was discontinued because of an arthroplasty. Fifty-eight months after beginning first-line treatment, the patient remains free from relapse. Adverse effects were minimal and easily controlled.

Keywords: Metastatic colorectal cancer; Bevacizumab; Maintenance

Core tip: A colorectal cancer patient with lung metastases received bevacizumab combined with chemotherapy for six months, and then bevacizumab monotherapy as maintenance treatment for more than three years. The patient achieved a complete response without evidence of side effects. He remains relapse free 58 mo after diagnosis.
