This letter must include a statement that affirms that all authors agree with the submission. Submission of an article for publication implies the transfer of the copyright from the author to the publisher upon acceptance. Accepted papers become the permanent property of Tumor Biology and may not be reproduced by any means, in whole or in part, without the written consent of the publisher and the Editor in Chief. It is the author's responsibility to obtain permission to reproduce illustrations, tables, etc. from other publications. When essential, number consecutively and type at the foot of the appropriate page.
Tables require a heading and figures a legend, also prepared on a separate sheet.
Due to technical reasons, figures with a screen background should not be submitted. On the back of each illustration, indicate its number, the author's name, and 'top' with a soft pencil. Color illustrations are reproduced at the author's expense. The number of references should not normally exceed 30. Material submitted for publication but not yet accepted should be noted as 'unpublished data' and not be included in the reference list.
