Colorectal cancer is the second leading cause of death from cancer in the developed countries. Although great efforts have been made to early diagnosis a relevant number of cases will present metastases. The natural history of metastatic Colorectal Cancer (mCRC) has dramatically evolved in the recent years thanks to the introduction of modern chemotherapy. Nowadays with the new drugs, such as oxaliplatin and irinotecan or modern drugs based on molecular targets (bevacizumab or cetuximab) the response rate has increased to 50% and the survival has been improved not only progression free survival, which has reached 12 months, but also overall survival which is longer than 2 years. Despite this progress many questions remain to be answered, mainly those related to the sequential regimens, drug rotation, alternant or intermitent schedules, optimal duration of chemotherapy, the role of maintenance chemotherapy and the role of doublets or triplets. The optimal duration of chemotherapy is very important because it has a direct influence on the patient quality of life, survival and costs. There are several studies addressing this topic and the alternatives we have, such as ├ó┬?┬?stop and go├ó┬?┬Ł, intermittent strategies or maintenance of only several agents and these studies reinforce the frequent behaviour of the oncologists to stop the treatment when the patient has obtained the maximum response. But there are some methodological problems in the analyzed trials which have determined that not all the professionals agree with this proposal. With this context it is essential to perform well designed clinical trials incorporating new drugs and addressing these questions. This presentation tries to review all these controversial points.
