The editors of Journal of Clinical Oncology identified a published paper in Annals of Oncology that appeared to represent a case of redundant publication involving the following articles: Long-term survival results of a randomized trial comparing gemcitabine plus cisplatin, with methotrexate, vinblastine,doxorubicin, plus cisplatin in patients with bladder cancer. Hans von der Maase, Lisa Sengelov, James T. Roberts, Sergio Ricci, Luigi Dogliotti, T. Oliver, Malcolm J. Moore, Annamaria Zimmermann, and Michael Arning. J Clin Oncol 2005; 23: 4602–4608. DOI:10.1200/JCO.2005.07.757. Long-term survival results of a randomized trial comparing gemcitabine/cisplatin and methotrexate/vinblastine/doxorubicin/cisplatin in patients with locally advanced and metastatic bladder cancer. J. T. Roberts, H. von der Maase, L. Sengeløv, P. F. Conte, L. Dogliotti, T. Oliver, M. J. Moore, A. Zimmermann and M. Arning. Ann Oncol 2006; 17 (Supplement 5): v 118–v 122. DOI:10.1093/annonc/mdj965. Following the Committee on Publication Ethics guidelines, the editors of Annals of Oncology have analyzed these two articles and after communication with several of the authors have confirmed that this in indeed the case and we, the editors, hereby retract the redundant Annals article to correct the published record. Annals of Oncology apologizes on behalf of all concerned.
