EXPRESSION OF CONCERN
Concerns have been raised by readers about the accuracy and validity of the data reported in the November 1, 2005, Journal of Clinical Oncology (JCO) article by Abdelkefi et al, entitled "Randomized Trial of Catheter-Related Bloodstream Infection by Continuous Infusion of Low-Dose Unfractionated Heparin in Patients With Hematologic and Oncologic Disease" (J Clin Oncol 23:7864–7870, 2005). When asked by JCO to provide evidence that the study was conducted, including primary source documents demonstrating that data were appropriately collected and analyzed, neither the authors nor the institution where the research took place was able to provide this information. Rather, the author informed JCO that the primary data were lost and not recoverable. Because JCO has no means of establishing the data or demonstrating that research results presented in this article are reproducible, JCO is publishing this Expression of Concern.
