title: [The prescribing of CA 15.3 in the Roubaix health insurance district].
abstract: OBJECTIVE
  Appreciate medical practice concerning CA 15.3 indications.
  
  
  METHODS
  Starting with dosages reimbursed to people on social security, the health service near the primary Health care assurance offices (caisse primaire d'assurance maladie) at Roubaix, conducted a study over a period of 3 months, in which they asked physicians for their reasons for prescribing CA 15.3.
  
  
  RESULTS
  Of the 205 questionnaires at their disposal, only 58 prescriptions conformed to the guidelines (28.3%). Prescriptions from specialists conformed in 48.9% of cases, as opposed to 12.8% from general practitioners.
  
  
  CONCLUSIONS
  The estimated assessment of the immediate additional expenditure will be shown to be 4 million Euros a year, over the whole of France.
