title: Dealing with metastatic breast cancer in elderly women: results from a French study on a large cohort carried out by the 'Observatory on Elderly Patients'.
abstract: BACKGROUND
  Treatment of elderly patients with metastatic breast cancer (MBC) is not clearly defined and seems to vary according to the subjective appreciation of the physician.
  
  
  METHODS
  After interviewing 107 French specialists qualified in oncology, data concerning 1009 MBC patients were collected: 500 patients were between 65 and 74 years and 509 were >75 years of age. Differences in diagnosis and treatment strategy were analyzed for both age groups to identify the physician's criteria of choice and the eventual use of the geriatric assessment among those criteria.
  
  
  RESULTS
  At diagnosis, synchronous metastatic disease was more frequent in patients over 75 years old (52% versus 39%; P<0.001). Physicians indicated that treatment was based on age and on a subjective evaluation of the patient's general status. Sixty-eight per cent of younger patients and only 31% of older ones received chemotherapy (P<0.001). In the older group drug doses were lower than those usually recommended in three-quarters of cases. Only 10% of physicians considered that they under-treat patients using the FEC 50 regimen. Over 75 years of age, hormone therapy was offered to most patients, including 8% with hormone-independent tumors. Geriatric covariates were never considered. Geriatricians rarely, if ever, played a role in the therapeutic decision.
  
  
  CONCLUSIONS
  Inclusion of elderly patients with MBC in prospective trials is warranted to define standards of care and reduce heterogeneity in the decision-making process.
