The International Journal of Clinical Oncology (IJCO) welcomes original and review papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Priority is given to high-quality clinical articles, including prospective randomized studies, rather than retrospective studies. Basic and translational studies will only be accepted if they have obvious clinical significance. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that their content has not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
