title: The consensus statements on adjuvant chemotherapy in breast cancer. Fact or artifact.
abstract: The decision of the National Cancer Institute, in November of 1985, in favor of adjuvant chemotherapy in the treatment of the premenopausal patient was based on the analysis of randomized clinical trials. The authors have carefully evaluated five papers dealing with the trials and found in each of them some problem in the performance or statistics which makes us question the interpretation of the findings of a statistically significant advantage for adjuvant chemotherapy in premenopausal patients. In view of this, we suggest that all the studies being considered need to be checked for their validity and if a significant number have similar flaws to those in the five trials noted, then we suggest that it is not possible to come to conclusions reported by the consensus panel.
