e14580 Background: It has been consistently proven that pivotal clinical trials (PCT) for drug registration or new drug indications (NDI), sponsored by the pharmaceutical industry, obtain better results than independent confirmatory studies (ICS). The interplay between PCT and ICS has supported better treatment selections and more realistic expectations: hope vs hype.The aim of this paper is to analyze the amount of ICS publications in Oncology within the last decade. Methods: All new FDA approved oncological drugs or NDI for solid tumors between 2005 and 2017 were taken into account. The PCT that led to their approval were identified, and between October and November 2019 a thorough search for related ICS (published or ongoing) was conducted on MEDLINE, ASCO Abstracts, NEJM, Lancet Oncology, JAMA, JCO, Cancer, PLOS ONE, PLOS Medicine and www.Clinicaltrials.gov. Results: Fifty-five new drugs or NDI were analyzed (Abemaciclib, Abiraterone, Ado-trastuzumab emtasine, Afatinib, Alectinib, Atezolizumab, Avelumab, Axitinib, Bendamustine, Bevacizumab, Brigatinib, Cabozantinib, Ceritinib, Cobimetinib, Crizotinib, Dabrafenib, Degarelix, Denosumab, Durvalumab, Eribuline mesylate, Everolimus, Ipilimumab, Irinotecan liposome, Ixabepilone, Lapatinib, Lenvatinib, Necitumumab, Neratinib, Nilotinib, Niraparib, Nivolumab, Olaparib, Osimertinib, Paclitaxel protein bound, Palbociclib, Panitumumab, Pazopanib, Pembrolizumab, Pertuzumab, Ramucirumab, Regorafenib, Ribociclib, Rucaparib, SipuleucelT, Sonidegib, Sorafenib, Sunitinib, Topotecan, Trabectedin, Trametinib, Trastuzumab, Vandetanib, Vemurafenib, Vismodegib, Ziv-afilbercept). Until November 30, 2019, no published or ongoing ICS were found in any of the cases. Conclusions: a) For the past decade, none of the PCT used for approval of new oncological drugs or NDI were replicated by ICS (without pharmaceutical industry sponsorship). b) We ignore the reasons for these approval methods but they raise suspicion and unnecessary discomfort. c) From an ethical point of view, patients’ Informed Consent must specify that expected results for the new drug or NDI are based exclusively on trials sponsored by the selling pharmaceutical company, unless other ICS are published. d) The current state of affairs can only be reverted if regulatory agencies and the scientific community demand ICS as part of the drug approval process or post-marketing duties.

e16075 Background: For the past three decades, it has been observed in developed countries an increase in the incidence of RCC, at the expense of small tumors incidentally found. This study compares the epidemiology, treatment and evolution of the patients (pt) with incidental RCC (Group A) or clinical RCC (Group B). Methods: Between 1/1/2001 and 11/30/2016, 29,440 new pt with histological diagnosis of cancer were incorporated to the IOHM database. We selected all those coded under the WHO ICD10 code C64. The medical records were reviewed, registering the epidemiological data, treatments and evolution of each patient Results: We identified 828 pt out of 29,940 pt (2.8%) who met the inclusion criteria. Group A = 507 pt (61%) and Group B = 321 pt (39%). The table below shows the characteristics of both groups. Conclusions: 1) In this cohort the incidental diagnosis of RCC represented 60% of the cases and correlated with early stages and less aggressive tumors. 2) The appropriate selection of patients allowed partial nephrectomies in 103/828 Pt. (12% of the cases). 3) With a median follow-up of 30 months the survival rate of this population exceeded 90% in the early stages and was close to 50% in advanced cases. [Table: see text]
