[Clinical practice guideline: 2003 update of Standards, Options et Recommendations for first line palliative chemotherapy in patients with metastatic colorectal cancer (summary report)].

Context: The "Standards, Options and Recommendations" (SOR) project, which started in 1993, is a collaboration between the Federation of French Cancer Centres (FNCLCC), the 20 French Regional Cancer Centres, and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients.

Objectives: To update clinical practice guidelines for first line palliative chemotherapy in patients with metastatic colorectal cancer previously validated in 1995, then updated in 1997 and published again in 1998. These recommendations do not cover second line treatment.

Methods: The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts who define the CPGs according to the definitions of the Standards, Options and Recommendations project. Once the guidelines have been developed, they are reviewed by independent reviewers.

Results: This article is a summary version of the updated clinical practice guidelines with algorithms. The main questions addressed by the expert group in this update concerned (1) Which patients should be treated? (2) What is the best treatment duration? (3) Which treatment should be administered? The new data identified concerning which patients to treat and the duration of treatment were consistent with the data presented in the initial report and did not modify the original recommendations from 1997. The new data available represent stronger evidence than those in the original report (Two good-quality meta-analyses published since 1997). A new guideline concerning patients who are 75 years old or more has been added. Concerning, the new evidence identified has modified the guidelines for the therapeutic schema to adopt from 1997. These modifications concern irinotecan, oxaliplatin, oral fluoropyrimidines and methotrexate. Treatment with irinotecan or oxaliplatin associated with continuous 5FU infusion, modulated with folinic acid (LV5FU2-like) has become a standard. The use of oral fluoropyrimidines has become an option for patients who refuse hospitalisation or treatment by infusion. The use of methotrexate combined with 5FU is no longer recommended.
