It is important for patients with colorectal cancer to receive standard and reasonable treatment. There are many clinical practice guidelines for diagnosis and treatment of colorectal cancer. However, the most influential guidelines are NCCN, ESMO and NICE guidelines. NCCN guidelines are the most world-renowned guidelines from National Comprehensive Cancer Network of the United States; ESMO guidelines are promulgated by the European Society for Medical Oncology; NICE guidelines are guidance of diagnosis and management for colorectal cancer issued by the National Institute for Health and Care Excellence of the United Kingdom. They are very similar in case management and treatment principles. However, there are still some differences in indications for drugs, treatment of hereditary colorectal cancer, laparoscopy indication and management of ileus. Here we discuss some of these differences and provide a reference for standardization of colorectal cancer treatment in China.

Objective To summarize the current status and development of therapy for anal canal cancer. Methods Application of Medline database and CHKD database, with "anal canal cancer", "chemotherapy", "radiotherapy", "abdominoperineal resection" as key words search literature about anal canal cancer published from January 1996 to June 2009. Retrieval criteria: the epidemiology of anal canal cancer; the etiology of anal canal cancer; the clinical manifestation and classification of anal canal cancer; strategies and development of therapy for anal canal cancer. Sixty-seven of them met the retrieval criteria, while finally 22 related papers were analyzed. Results Over the last 30 years, treatment of anal canal cancer has undergone a profound evolution. Combined-modality treatment combined with chemoradiotherapy (CRT), including three-dimensional conformal radiation therapy (3D-CRT), intensity modulated radiation therapy (IMRT), novel anti-tumor agent and salvage surgery, had resulted in a 5-year survival rate of approximately 80 %. Conclusion Anal canal cancer is a rare tumor. CRT has replaced surgery as the first choice of anal canal cancer. The development of molecular biology will likely lead to further proposals for trials of anal canal cancer.

Objective:To investigate the expressions of peroxisome proliferator-activated receptor gamma (PPARγ), estrogen re-ceptor alpha (ERα), and estrogen receptor beta (ERβ) in endometrial carcinoma and to analyze their correlations and clinical signifi-cance. Methods:Immunohistochemical assay and Western blot were used to detect the expressions of PPARγ, ERα, and ERβin normal endometrial tissues and well-differentiated, moderately differentiated, and poorly differentiated endometrial carcinomas. Results:PPARγexpression was significantly lower in endometrial carcinoma than in the normal endometrium and was intimately associated with cli-ni-copathologic variables. ERαexpression gradually decreased in moderately and poorly differenti-ated endometrial carcinomas. How-ever, no significant differences were found between the normal endometrium and well-differentiated endometrial carcinoma. ERβex-pression only decreased in the poorly differentiated endometrial carcinoma. No significant association was observed between ERβand clinicopathologic variables. Pearson correlation analysis showed a significant positive cor-relation between the expressions of PPARγand ERα. No correlations were observed between the expressions of ERαand ERβand between that of ERβand PPARγ. Conclusion:The expression lev-els of PPARγand ERαwere significantly associated with the clinicopathologic stage of endometrial carcinoma, and have essential functions in endometrial tumorigenesis and tumor progression.
