1Transrectal ultrasound and magnetic resonance imaging measurement of extramural tumor spread in rectal cancer显示文摘AIM:To evaluate the agreement between transrectal ultrasound(TRUS) and magnetic resonance imaging(MRI) in classification of ≥ T3 rectal tumors.METHODS:From January 2010 to January 2012,86 consecutive patients with ≥ T3 tumors were included in this study.The mean age of the patients was 66.4 years(range:26-91 years).The tumors were all ≥ T3 on TRUS.The sub-classification was defined by the penetration of the rectal wall:a:0 to 1 mm;b:1-5 mm;c:6-15;d:> 15 mm.Early tumors as ab(≤ 5 mm) and advanced tumors as cd(> 5 mm).All patients underwent TRUS using a 6.5 MHz transrectal transducer.The MRI was performed with a 1.5 T Philips unit.The TRUS findings were blinded to the radiologist performing the interpretation of the MRI images and measuring the depth of extramural tumor spread.RESULTS:TRUS found 51 patients to have an early ≥ T3 tumors and 35 to have an advanced tumor,whereas MRI categorized 48 as early ≥ T3 tumors and 38 as advanced tumors.No patients with tumors classified as advanced by TRUS were found to be early on MRI.The kappa value in classifying early versus advanced T3 rectal tumors was 0.93(95% CI:0.85-1.00).We found a kappa value of 0.74(95% CI:0.63-0.86) for the total sub-classification between the two methods.The mean maximal tumor outgrowth measured by TRUS,5.5 mm ± 5.63 mm and on MRI,6.3 mm ± 6.18 mm,P = 0.004.In 19 of the 86 patients the following CT scan or surgery revealed distant metastases;of the 51 patients in the ultrasound ab group three(5.9%) had metastases,whereas 16(45.7%) of 35 in the cd group harbored distant metastases,P = 0.00002.The odds ratio of having distant metastases in the ultrasound cd group compared to the ab group was 13.5(95% CI:3.5-51.6),P = 0.00002.The mean maximal ultrasound measured outgrowth was 4.3 mm(95% CI:3.2-5.5 mm) in patients without distant metastases,while the mean maximal outgrowth was 9.5 mm(95% CI:6.2-12.8 mm) in the patients with metastases,P = 0.00004.Using the MRI classification three(6.3%) of 48 in the MRI ab group had distant metastases,while 16(42.1%) of the 38 in the MRI cd group,P = 0.00004.The MRI odds ratio was 10.9(95% CI:2.9-41.4),P = 0.00008.The mean maximal MRI measured outgrowth was 4.9 mm(95% CI:3.7-6.1 mm) in patients without distant metastases,while the mean maximal outgrowth was 11.5 mm(95% CI:7.8-15.2 mm) in the patients with metastases,P = 0.000006.CONCLUSION:There is good agreement between TRUS and MRI in the pretreatment sub-classification of ≥ T3 tumors.Distant metastases are more frequent in the advanced group.Sφren R Rafaelsen Chris Vagn-Hansen Torben Sφrensen John Plφen Anders Jakobsen 2012World Journal of Gastroenterology2012,18,36:14
2Gut-brain connection: The neuroprotective effects of the anti-diabetic drug liraglutide显示文摘Long-acting glucagon-like peptide-1(GLP-1) analogues marketed for type 2 diabetes(T2D) treatment have been showing positive and protective effects in several different tissues, including pancreas, heart or even brain. This gut secreted hormone plays a potent insulinotropic activity and an important role in maintaining glucose homeostasis. Furthermore, growing evidences suggest the occurrence of several commonalities between T2 D and neurodegenerative diseases, insulin resistance being pointed as a main cause for cognitive decline and increased risk to develop dementia. In this regard, it has also been suggested that stimulation of brain insulin signaling may have a protective role against cognitive deficits. As GLP-1 receptors(GLP-1R) are expressed throughout the central nervous system and GLP-1 may cross the blood-brain-barrier, an emerging hypothesis suggests that they may be promising therapeutic targets against brain dysfunctional insulin signaling-related pathologies. Importantly, GLP-1 actions depend not only on the direct effect mediated by its receptor activation, but also on the gut-brain axis involving an exchange of signals between both tissues via the vagal nerve, thereby regulating numerous physiological functions(e.g., energy homeostasis, glucose-dependent insulin secretion, as well as appetite and weight control). Amongst the incretin/GLP-1 mimetics class of anti-T2 D drugs with an increasingly described neuroprotective potential, the already marketed liraglutide emerged as a GLP-1R agonist highly resistant to dipeptidyl peptidase-4 degradation(thereby having an increased half-life) and whose systemic GLP-1R activity is comparable to that of native GLP-1. Importantly, several preclinical studies showed anti-apoptotic, anti-inflammatory, anti-oxidant and neuroprotective effects of liraglutide against T2 D, stroke and Alzheimer disease(AD), whereas several clinical trials, demonstrated some surprising benefits of liraglutide on weight loss, microglia inhibition, behavior and cognition, and in AD biomarkers. Herein, we discuss the GLP-1 action through the gut-brain axis, the hormone's regulation of some autonomic functions and liraglutide's neuroprotective potential.Emanuel Monteiro Candeias Inês Carolina Sebastio Susana Maria Cardoso Sónia Catarina Correia Cristina Isabel Carvalho Ana Isabel Plácido Maria Sancha Santos Catarina Resende Oliveira Paula Isabel Moreira Ana Isabel Duarte 2015World Journal of Diabetes2015,6,6:9
3Clinical significance of lymphadenectomy in patients with gastric cancer显示文摘Approximately thirty percent of patients with gastric cancer undergo an avoidable lymph node dissection with a higher rate of postoperative complication. Comparing the D1 and D2 dissections,it was found that there is a significant difference in morbidity,favoured D1 dissection without any difference in overall survival. Subgroup analysis of patients with T3 tumor shows a survival difference favoring D2 lymphadenectomy,and there is a better gastric cancer-related death and non-statistically significant improvement of survival for node-positive disease in patients with D2 dissection. However,the extended lymphadenectomy could improve stage-specific survival owing to the stage migration phenomenon. The deployment of centralization and application of national guidelines could improve the surgical outcomes. The Japanese and European guidelines enclose the D2 lymphadenectomy as the gold standard in R0 resection. In the individualized,stageadapted gastric cancer surgery the Maruyama computer program(MCP) can estimate lymph node involvement preoperatively with high accuracy and in addition the Maruyama Index less than 5 has a better impact on survival,than D-level guided surgery. For these reasons,the preoperative application of MCP is recommended routinely,with an aim to perform 'low Maruyama Index surgery'. The sentinel lymph node biopsy(SNB) may decrease the number of redundant lymphadenectomy intraoperatively with a high detection rate(93.7%) and an accuracy of 92%. More accurate stage-adapted surgery could be performed using the MCP and SNB in parallel fashion in gastric cancer.dezso tóth jános plósz miklós torok 2016World Journal of Gastrointestinal Oncology2016,8,2:8
