Differential distribution and enrichment of non-coding RNAs in exosomes from normal and Cancer-associated fibroblasts in colorectal cancer.
Exosome production from cancer-associated fibroblasts seems to be an important driver of tumor progression. We report the first in-depth biotype characterization of ncRNAs, analyzed by Next Generation Sequencing and Bioinformatics, expressed in established primary human normal and cancer-associated fibroblasts (CAFs) from cancer and normal mucosa tissues from 9 colorectal cancer patients, and/or packaged in their derived exosomes. Differential representation and enrichment analyses based on these ncRNAs revealed a significant number of differences between the ncRNA content of exosomes and the expression patterns of the normal and cancer-associated fibroblast cells. ncRNA regulatory elements…

Identification of quality care indicators in prostate cancer.
213 Background: Despite the attempts made to improve prostate cancer management with the development and implementation of clinical practice guidelines, the inefficiencies and differences that usually occur in ordinary clinical care of patients with prostate cancer significantly contribute to increase the variations in the patterns of care and patients outcomes, and costs to the health system. The goal of this project was to establish parameters for improving the care of patients with prostate cancer through the development and validation of quality indicators for the management of this disease. Methods: The ECO Foundation is a platform of experts representing the major Spanish hospitals i…

Implementation of the quality training program in Spain.
e18296 Background: The ECO Foundation is a collaboration of experts representing the major Spanish hospitals in the pursuit of excellence in cancer treatment. Since 2015, ECO has been collaborating with ASCO (American Society of Clinical Oncology) in quality initiatives in cancer care, like the QOPI (Quality Oncology Practice Initiative) program and the QOPI Certification Program (QCP). The Quality Training Program (QTP) is a 6-month program with 3 in-person learning sessions that prepares oncology teams to design implement and lead successful quality improvement activities in their practices. In 2018, ECO reached a new agreement with ASCO to implement this program in Spain. Methods: The Q…
Phase II Trial of Preoperative Irinotecan–Cisplatin Followed by Concurrent Irinotecan–Cisplatin and Radiotherapy for Resectable Locally Advanced Gastric and Esophagogastric Junction Adenocarcinoma
Purpose To determine in a Phase II trial whether preoperative irinotecan–cisplatin (IC) followed by concurrent IC therapy and radiotherapy (IC/RT) improved outcome in patients with resectable, locally advanced gastric adenocarcinoma (GC) or esophagogastric junction cancer (EGJC). Patients and Methods Patients with resectable Stage II–IV, M0 GC or EGJC made up the study population. The primary endpoint was pathologic complete response (pCR). Two courses of IC (irinotecan, 65mg/m 2 ; cisplatin, 30mg/m 2 on Days 1 and 8 every 21 days) were given. Patients without progression then received IC/RT, consisting of daily radiotherapy (45Gy) with concurrent IC (irinotecan, 65mg/m 2 ; cisplatin, 30mg/…

Treatment patterns for metastatic colorectal cancer in Spain
Abstract Purpose The primary aim of this retrospective study was to describe the treatment patterns according to the type of treatment received by patients with metastatic colorectal cancer (mCRC) in Spain. Methods This was a retrospective, observational, multicenter study performed by 33 sites throughout Spain that included consecutive patients aged 18 years or older who had received or were receiving treatment for mCRC. Results At the time of inclusion, of the 873 evaluable patients, 507 (58%) had received two lines, 235 (27%) had received three lines, 106 (12%) had received four lines, and the remaining patients had received up to ten lines. The most frequent chemotherapy schemes were th…

Efficacy of trifluridine and tipiracil (TAS-102) versus placebo, with supportive care, in a randomized, controlled trial of patients with metastatic colorectal cancer from Spain: results of a subgroup analysis of the phase 3 RECOURSE trial
[Purpose] TAS-102 is a combination of the thymidine-based nucleoside analog trifluridine and the thymidine phosphorylase inhibitor tipiracil. Efficacy and safety of TAS-102 in patients with metastatic colorectal cancer (mCRC) refractory or intolerant to standard therapies were evaluated in the phase 3 RECOURSE trial. Results of RECOURSE demonstrated significant improvement in overall survival (OS) and progression-free survival (PFS) with TAS-102 versus placebo [hazard ratio (HR) = 0.68 and 0.48 for OS and PFS, respectively; both P < 0.001]. The current analysis evaluates efficacy and safety of TAS-102 in the RECOURSE Spanish subgroup.
Analysis of Heritability and Shared Heritability Based on Genome-Wide Association Studies for Thirteen Cancer Types
BACKGROUND: Studies of related individuals have consistently demonstrated notable familial aggregation of cancer. We aim to estimate the heritability and genetic correlation attributable to the additive effects of common single-nucleotide polymorphisms (SNPs) for cancer at 13 anatomical sites.METHODS: Between 2007 and 2014, the US National Cancer Institute has generated data from genome-wide association studies (GWAS) for 49 492 cancer case patients and 34 131 control patients. We apply novel mixed model methodology (GCTA) to this GWAS data to estimate the heritability of individual cancers, as well as the proportion of heritability attributable to cigarette smoking in smoking-related cance…

Study on compliance with breakthrough cancer pain guidelines by medical oncologists in Spain.
e18260 Background: Breakthrough cancer pain (BTcP) has been shown to be a prevalent and poor prognostic factor for cancer patients, which remains undertreated and underdiagnosed. The Spanish Society for Medical Oncology (SEOM) developed a clinical practice guideline (CPG) for the treatment of cancer pain which specifically addressed the management of BTcP. Methods: With the objective of evaluate compliance with SEOM’ guideline, Fundación ECO designed a survey to identify awareness, perceptions, implementation and gaps, among Spanish medical oncologists. Results: A total of 83 oncologists with a median experience of 13 years responded. Although 87% of oncologists considered their clinical p…

Heatmap with dendrogram showing the over-represented sncRNAs in CAF exosomes supported by FDRs below 1E-04 with the GO terms and metabolic pathways annotated to the predicted target genes summarized in Table 2. The number of target genes is used to color the breaks. If a sncRNA has no target gene assigned to a metabolic pathway (absence), the intersecting cell is colored white; if a ncRNA has one target gene assigned to a pathway, the cell is colored gray; and if more than two target genes are assigned to a pathway, it is colored black. The clustering was inferred by using the complete linkage with the Euclidean distance measure. (PNG 578 kb)
