Colorectal cancer (CRC) is an aggressive malignancy that has a poor prognosis. 5-Fluorouracil (5-FU) is a first line chemotherapeutic medication used in the treatment of gallbladder cancer; however, the efficacy is below satisfactory. Icariin is a natural compound that is conventionally reported to have activity against a variety of cancers.

Aim: To investigate the short-term outcome of laparoscopic total mesorectal excision (TME) in patients with mid and low rectal cancers.

Methods: A consecutive series of 138 patients with middle and low rectal cancer were randomly assigned to either the laparoscopic TME (LTME) group or the open TME (OTME) group between September 2008 and July 2011 at the Department of Colorectal Cancer of Shanghai Cancer Center, Fudan University and pathological data, as well as surgical technique were reviewed retrospectively. Short-term clinical and oncological outcome were compared in these two groups.

Objective: To prospectively evaluate the safety and efficacy of nickel- titanium temperature-dependent memory-shape device(CAR27) for colorectal anastomosis.

Methods: Sixty colorectal cancer patients were randomly divided into two groups and received colorectal anastomosis with CAR27 or traditional stapling device. Complications, bowel function return, and the extrusion of anastomosis ring were prospectively monitored.

Aim: To develop lymph node metastasis (LNM)-associated biomarkers for colorectal cancer (CRC) using quantitative proteome analysis.

Methods: Differences in protein expression between primary CRC with LNM (LNM CRC) and without LNM (non-LNM CRC) were assessed using methyl esterification stable isotope labeling coupled with 2D liquid chromatography followed by tandem mass spectrometry (2D-LC-MS/MS). The relationship to clinicopathological parameters and prognosis of candidate biomarkers was examined using an independent sample set.

Objective: To evaluate the safety and efficacy of a novel nickel-titanium memory alloy compression anastomosis ring(CAR27) for colorectal anastomosis.

Methods: One sigmoid cancer patient undergone lower anterior resection(LAR) received colorectal anastomosis with CAR27 on November 12, 2009. The following parameters were recorded during 4 weeks postoperative follow-up:colorectal anastomotic complication,first post-operation flatus and bowel movement, extrusion of ring device.

Objective: To explore the relationship between CpG island methylator phenotype(CIMP) and genetic instability in sporadic colorectal cancer(SCRC).

Methods: Seventy-one SCRC patients were enrolled in this study. Promotor methylation status of five genes including P14(ARF ), hMLH1, P16(INK4a), MGMT and MINT1 was detected with methylation specific PCR to confirm CIMP.

Aim: To explore the prognostic variables in rectal cancer patients undergoing curative total mesorectal excision and the effect of postoperative chemotherapy in advanced rectal cancer.

Methods: A total of 259 consecutive rectal cancer patients treated with curative total mesorectal excision between 1999 and 2004 were collected. p53, p21, PCNA, and CD44v6 were examined using immunohistochemistry (IHC).

Aim: To study the clinical characteristics of hereditary nonpolyposis colorectal cancer (HNPCC) in the Chinese population and discuss the identification and management of the patients with HNPCC.

Methods: A series of 140 patients with colorectal cancers (CRC) and HNPCC associated tumors from 30 families fulfilling the Amsterdam criteria were analyzed.

Results: A total of 118 patients had CRC.
