Association of mechanical bowel preparation with oral antibiotics and anastomotic leak following left sided colorectal resection: an international, m…
2018
INTRODUCTION: The optimal bowel preparation strategy to minimise the risk of anastomotic leak is yet to be determined. This study aimed to determine whether oral antibiotics combined with mechanical bowel preparation (MBP+Abx) was associated with a reduced risk of anastomotic leak when compared to mechanical bowel preparation alone (MBP) or no bowel preparation (NBP).METHODS: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 Left Sided Colorectal Resection audit was performed. Patients undergoing elective left sided colonic or rectal resection with primary anastomosis between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary out…
The colovescical fistula in diverticular disease: Laparoscopic approach in two different cases
2020
Highlights • The colovescical fistula is one of the complications of diverticular disease. • It can cause typical symptoms like pneumaturia and fecaluria affecting the quality of life and sometimes leading to death, usually secondary to sepsis. • We studied two patients with clinical, radiological and endoscopic diagnosis of colovescical fistula as a consequence of diverticular disease. • We performed a totally laparoscopic treatment with colonic resection and closure of the fistula with intracorporeal sutures. • The presence of a colovescical fistula significantly increases the difficult of the laparoscopic colonic resection.
Meta-analysis of mismatch repair polymorphisms within the cogent consortium for colorectal cancer susceptibility
2013
In the last four years, Genome-Wide Association Studies (GWAS) have identified sixteen low-penetrance polymorphisms on fourteen different loci associated with colorectal cancer (CRC). Due to the low risks conferred by known common variants, most of the 35% broad-sense heritability estimated by twin studies remains unexplained. Recently our group performed a case-control study for eight Single Nucleotide Polymorphisms (SNPs) in 4 CRC genes. The present investigation is a followup of that study. We have genotyped six SNPs that showed a positive association and carried out a meta-analysis based on eight additional studies comprising in total more than 8000 cases and 6000 controls. The estimate…
Hypoxia-inducible factor 1 alpha expression increases during colorectal carcinogenesis and tumor progression
2008
Abstract Background Hypoxia-inducible factor 1 alpha (HIF-1α) is involved in processes promoting carcinogenesis of many tumors. However, its role in the development of colorectal cancer is unknown. To investigate the significance of HIF-1α during colorectal carcinogenesis and progression we examined its expression in precursor lesions constituting the conventional and serrated pathways, as well as in non-metastatic and metastatic adenocarcinomas. Methods Immunohistochemistry and Western blot is used to analyse HIF-1α expression in normal colonic mucosa, hyperplastic polyps (HPP), sessile serrated adenomas (SSA), low-grade (TA-LGD) and high-grade (TA-HGD) traditional adenomas as well as in n…
Multisciplinary management of patients with liver metastasis from colorectal cancer
2016
Abstract: Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to res…
Estudio de acetilación de proteínas en líneas celulares humanas de cáncer colorectal KRAS mutado y salvaje
2016
El estado mutacional de KRAS es el principal predictor negativo de respuesta a terapias anti-factor de crecimiento epidérmico (EGFR) en pacientes diagnosticados de cáncer colorectal avanzado (CRC). Sin embargo existe datos contradictorios sobre las causas de la respuesta variable a estos fármacos diana de acuerdo con la presencia de mutaciones, de hecho publicaciones recientes han presentado datos no concluyentes sobre los pacientes portadores de mutaciones en el codón 13. En nuestro trabajo, hemos estudiado el impacto de la presencia de mutaciones en KRAS en proteínas intracelulares no histónicas. Para ello hemos utilizado diferentes líneas celulares de cáncer colorectal portadoras de dife…
Cancer in Elderly Onset Inflammatory Bowel Disease: A Population-Based Study.
2016
IF 10.383; International audience; OBJECTIVES: Cancer may be a complication of inflammatory bowel disease (IBD) or its treatment. In elderly onset IBD patients the risk of malignancy is of particular concern. We studied this risk in a population-based cohort of elderly onset IBD patients.METHODS: In a French population-based cohort, we identified 844 patients aged >60 years at IBD diagnosis from 1988 to 2006, including 370 Crohn's disease (CD) and 474 ulcerative colitis (UC). We compared incidence of cancer among IBD patients with that observed in the French Network of population-based Cancer Registries (FRANCIM). Confidence interval (CI) was estimated assuming a Poisson-specific law for ra…
Analysis of RET promoter CpG island methylation using methylation-specific PCR (MSP), pyrosequencing, and methylation-sensitive high-resolution melti…
2016
Background Already since the 1990s, promoter CpG island methylation markers have been considered promising diagnostic, prognostic, and predictive cancer biomarkers. However, so far, only a limited number of DNA methylation markers have been introduced into clinical practice. One reason why the vast majority of methylation markers do not translate into clinical applications is lack of independent validation of methylation markers, often caused by differences in methylation analysis techniques. We recently described RET promoter CpG island methylation as a potential prognostic marker in stage II colorectal cancer (CRC) patients of two independent series. Methods In the current study, we analy…
Efficacy of trifluridine and tipiracil (TAS-102) versus placebo, with supportive care, in a randomized, controlled trial of patients with metastatic …
2016
[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.
