Abstract
Purpose of Review
Current systemic management of MCRC should include periods of intensive and less intensive treatment or even complete stop. Different systemic post-induction strategies have been evaluated in many trials. The aim of this article is to review the available data on maintenance strategies in MCRC and potential options to personalize choice of the respective strategy.
Recent Findings
Despite the large variability of clinical trials conducted in this setting, it can be concluded that intermittent chemotherapy does not seem to be inferior to continuous chemotherapy if at least 3 months of intensive induction treatment is applied, and active maintenance seem to be superior to complete stop after at least 3 months of induction treatment in terms of PFS and may add some benefit in terms of OS. The choice of the respective maintenance strategy may be personalized taking into account disease and patient characteristic, choice of induction treatment and response, treatment tolerability and quality of life.
Summary
Patients with metastatic colorectal cancer and no options of secondary resection or local ablation should be considered for a personalized maintenance approach.

The CAIRO3 study was designed to determine the efficacy of maintenance treatment with capecitabine plus bevacizumab versus observation. It showed that maintenance treatment with capecitabine plus bevacizumab after six cycles of CAPOX-B in patients with metastatic colorectal cancer prolongs progression free survival and does not compromise quality of life.

Randomized trial investigating different maintenance strategies after first-line induction treatment with fluoropyrimidine, oxaliplatin and bevacizumab. An active maintenance treatment, either with a fluoropyrimidine plus bevacizumab or with bevacizumab alone, is associated with a longer progression free survival, but choice of maintenance or post-induction strategy does not affect overall survival.

Ann Oncol. 2016;27(12):2203–10. doi:10.1093/annonc/mdw425. This was one of the first studies analysing quality of life during maintenance treatment. The study showed that continuation of an active maintenance treatment with fluoropyrimidine and bevacizumab after induction treatment was neither associated with a detrimental effect on health related quality of life when compared to bevacizumab alone or no active treatment.
