Novel Expanding Renal Cell Carcinoma Biomarkers
Identification of reliable molecular biomarkers that can complement clinical practice represents a fascinating challenge in any cancer field. Renal tumors are usually asymptomatic and incidentally identified during imaging studies due to unrelated causes. However, in 25-30% of patients the first diagnosis is accompanied by symptoms and associated with distant metastasis. Thus, early diagnosis may improve the disease progression also avoiding side effects of inadequate treatments. Moreover, the ability to categorize patients' risk of recurrence after radical treatment, or even predict benefit from a target therapy represent a compelling challenge. Here we reviewed the current state-of-the-art on RCC biomarkers, particularly focusing on the new approaches of genomics, liquid biopsy, proteomics and metabolomics.
The Société International d'Urologie (SIU), which owns and publishes the Société International d'Urologie Journal (SIUJ), does not require authors of papers published in the journal to transfer copyright. Instead, we ask authors to grant an exclusive licence that allows us to publish the article in SIUJ (and any derivative or related products or publications) and that allows us to sub-license such rights and exploit all subsidiary rights.
Authors retain the right to use their own articles for their own non-commercial purposes without seeking explicit permission from SIU.
The SIUJ publication licence expressly defines “non-commercial” as “not primarily intended for or directed towards commercial advantage or monetary compensation.” Although no activity is completely disconnected from commercial activity, the following are generally considered to be non-commercial uses:
- Reproduction of a reasonable number (no more than 100) of print copies of the published paper for personal use (e.g., sharing with colleagues, including in grant applications).
- Posting a copy of the published version of the paper on the author’s own or their institution’s website. The article must be accompanied by this statement: ‘This article has been published in the SIUJ: [full citation; link]’.
- Inclusion of the paper in a course pack, with a maximum of 100 copies to be used in the author’s institution. The copies must include the following acknowledgement: ‘This article has been published in the SIUJ: [full citation; link].’
As the distinction between commercial and non-commercial is not always clear, authors are strongly advised to seek permission from SIU for any use that may be considered to have a commercial aspect.
We ask the corresponding author to read the terms of the licence and then to grant this exclusive licence on behalf of all authors by indicating agreement to the following statement:
The corresponding author has the right to grant on behalf of all authors and does grant on behalf of all authors, an exclusive licence on a worldwide basis to the SIU and its licensees to permit this article (if accepted) to be published in the SIUJ and any other SIU products and publications and to exploit all subsidiary rights, as set out in our licence agreement.
