  • Diagnostic Value of Aberrant Methylation of Genes in Stool for Colorectal Tumor: A Meta-Analysis

    Objective To evaluate the diagnostic accuracy of the aberrant methylation of genes in stool for colorectal tumor. Methods Databases including The Cochrane Library, PubMed, EMbase, CBM, Web of Science, CNKI and WanFang Data were searched to collect the diagnostic trials on the aberrant methylation of genes in stool for colorectal tumor published from January 1990 to February 2012. QUADAS items were used to evaluate the quality of the included studies, and the meta-analysis was conducted using Meta-Disc 1.4 software. Results A total of 32 studies involving 3 951 patients were included. The results of meta-analysis showed that, for detecting the colorectal tumor, the weighted sensitivity, specificity, diagnostic odds ratio (DOR), area under the summary receiver operating characteristic (SROC) curve and Q were 92% (95%CI 91% to 93%), 63% (95%CI 61% to 65%), 20.79 (95%CI 15.13 to 28.57), 0.861 9 (SE=0.020 4), and 0.792 6 (SE=0.019 8), respectively. For detecting the colorectal cancer, the weighted sensitivity, specificity and area under the curve (AUC) were 91% (95%CI 89% to 92%), 75% (95%CI 73% to 77%), and 0.900 7, respectively. For detecting the colorectal adenoma, the weighted sensitivity, specificity and AUC were 79% (95%CI 76% to 83%), 75% (95%CI 73% to 77%), and 0.845 7, respectively. Conclusion With high sensitivity (92%) and moderate specificity (63%), aberrant methylation of genes in stool can be used as an optional noninvasive method for the diagnosis of colorectal tumor.

  • Clinical Effect of Restrict Rehydration Strategy on Elderly Patients with Colorectal Cancer in Fast-Track

    Objective To explore the effect of restrictive fluid administration on elderly patients with colorectal cancer in fasttrack.Methods From January 2008 to January 2009, the elderly patients (≥60 years old) diagnosed definitely as colorectal cancer were analyzed retrospectively, the clinical effects on post-operative early rehabilitation were studied and the difference between restrictive fluid regimen and tradition fluid regimen was compared. Results The difference of overall incidence of post-operative complications was statistically significant between the two groups (Plt;0.05). The incidences of anastomotic leakage and pulmonary infection of fluid restriction group were lower than those of tradition therapy group (Plt;0.05). The time of vent to normal, defecation to normal and postoperative first eating of fluid restriction group was shorter than those of tradition therapy group, the difference was statistically significant (Plt;0.05). Comparing the biochemical indicators, the difference of preoperative GLU 〔(6.70±2.93) mmol/L vs. (6.33±3.95) mmol/L〕, BUN 〔(5.84±2.03) mmol/L vs. (7.32±10.83) mmol/L〕and CREA 〔(76.19±19.85) μmol/L vs. (85.36±38.02) μmol/L)〕 was statistically significant (Plt;0.05), but the difference of postoperative results had no statistical significance. Conclusion Restrictive fluid regimen can reduce the incidence of common complications after colorectal surgery for elderly patients, and have a certain promoter action to the early rehabilitation after rectal surgery.

  • Case-Control Study of Colorectal Cancer Combined-Therapy in Multi-Disciplinary Team

    Objective  To discuss the performance of multi-disciplinary team (MDT) of colorectal cancer treatment within West China Hospital in Sichuan University. Methods  To compare the therapeutic effect between groups of MDT model and non-MDT model by retrospectively analyzing the data of patients who diagnosed colorectal cancer and accepted in-hospital therapy during December 2006 and May 2007. Results  The in-hospital days of the MDT model group during the perioperative period and in the surgical ward were less than that of the non-MDT model group ( Plt; 0. 05) , but there was no significant difference between the two groups about the total hospitalization time. And the MDT model group had a higher rate of cancer resection ( P lt; 0. 05) . Although the incidence of anastomotic leakage and bleeding as early postoperative complications didn’t show any variations between the two groups , the non-MDT model groupencountered more early postoperative ileus ( Plt; 0. 05) . During the 5- 10 months follow-up , there came out less cancer recurrence rate in the MDT model group than the other ( P lt; 0. 05) . And the morbidity of anastomotic stricture and ileus didn’t show any statistical difference between the two groups. Conclusion  The combined-therapy st rategy ofcolorectal cancer has showed a priority to routine ways , not only the more reasonable time arrangement for therapy , but also the more satisfied surgical outcomes. However , the factors correlated to the efficacy of the MDT model are not clear ; the MDT model still needs to be improved that a morereasonable and effective perioperative MDT model may come t rue.

  • Reporting Quality of Randomized Controlled Trials on Laparoscopic Surgery for Treating Colorectal Disease in Three SCI Indexed Journals

    Objective To investigate the reporting quality of randomized controlled trials (RCT) on laparoscopic surgery for treating colorectal disease in three SCI indexed. Methods We electronically retrieved the Ovid MEDLINE(R) from 1950 to present with Daily Updates for RCTs on laparoscopic surgery published in Diseases of the Colon amp; Rectum, International Journal of Colorectal Disease, or Colorectal Disease. The revised CONSORT statement and additional surgical items were adopted to assess the reporting quality. One point was assigned for each full description of an item, 0 for no description, and 0.5 for a partial description. Results A total of 20 RCTs were included and 8 RCTs were excluded. Their reporting quality was low. The average scores for the following items were relatively lower, 0.150 for settings where data collected; 0.250 for sample size estimation; 0.500 for sequence generation of randomization; 0.325 for allocation concealment; 0.150 for implementation; 0.475 for measurement of outcome; 0.150 for participant flow chart; 0.450 for adverse events; 0.450 for external validity; 0.400 for financial conflicts of interest; 0.250 for perioperative pharmacological treatment; 0.075 for perioperative nonphamacological treatment; 0.000 for participation of a trial methodologist; 0.350 for surgeon’s experience (years or position). Items with the lower scores were mainly in the methods and results section and surgical items. Conclusions The reporting quality of laparoscopic RCTs in these journals is low. Colorectal surgeons should rigorously evaluate reports in these journals before they apply to them in clinical practice.

  • Evidence of Colorectal Tumor in Colorectal Cancer Group of the Cochrane Collaboration

    Until Issue 2 in 2008, the Cochrane Database of Systematic Reviews had included 23 systematic reviews concerning colorectal tumors by the colorectal cancer group. These reviews involved prevention, diagnosis, treatment, prognosis and follow-up. The preventive ability of non-steroid anti-inflammatory drugs, accuracy of chromoscopy, shortterm outcomes of laparoscopic colorectal resection and outcomes of laparoscopic total mesorectal excision were confirmed. Meanwhile, the effect of dietary fibre in prevention, mechanical preoperative preparation, and prophylactic anastomotic drainage was questioned. Because of the low quality of trials, no firm conclusions were revealed in some reviews, such as traditional Chinese medicine in chemotherapy. Through the study of Cochrane systematic reviews, medical practitioners and researchers can obtain high-quality evidence, and identify future research direction in the field of colorectal cancer.
