RESULTS Advanced gastric cancers with a high-risk macroscopic appearance were retrospectively identified by preoperative recorded images. A high-risk macroscopic appearance showed a significantly worse relapse free survival(RFS)(35.7%) and overall survival(OS)(34%) than an average risk appearance(P = 0.0003 and P < 0.0001, respectively). A high-risk macroscopic appearance was significantly associated with the 13^(th) Japanese Gastric Cancer Association(JGCA) pT(P = 0.01), but not with the 13^(th) JGCA pN. On univariate analysis for RFS and OS, prognostic factors included 13^(th) JGCA p Stage(P < 0.0001)and other clinicopathological factors including macroscopic appearance. A multivariate Cox proportional hazards model for univariate prognostic factors identified highrisk macroscopic appearance(P = 0.036, HR = 2.29 for RFS and P = 0.021, HR = 2.74 for OS) as an independent prognostic indicator. CONCLUSION A high-risk macroscopic appearance was associated with a poor prognosis, and it could be a prognostic factor independent of 13^(th) JGCA stage in p Stage Ⅱ/Ⅲ advanced gastric cancer.展开更多

Methods: One hundred cases with stage Ⅲ-Ⅳ NSCLC were randomly divided into two groups. The treated group (n=50) received CT combined with TCM, and the control group received CT alone. The percentage of T lymphocyte subset in peripheral blood and the change of natural killer (NK) cell count were observed after treatment. The QOL and tolerance of CT were also compared between the two groups after treatment. Results: In the treated group, CD3 cell count, CD4 cell count, CD4/ CDg ratio and NK cell activity were higher than those in control group, while CD8 cell count in the treated group was lower than that in the control group (P<0.05), and QOL and tolerance of CT in the treated group were also better (P<0.05). Conclusion: TCM combined with CT could raise the patients' ability in tolerating CT in stage Ⅲ-ⅣNSCLC.展开更多

It is estimated that over 35% of tumors are diagnosed at locally advanced disease, stage ⅠB2-ⅡB with an estimated 5-year overall survival of 60%. During the last decades, the initial treatment for these women has been debated and largely varies through different countries. Thus, radical concurrent chemoradiation is the standard of care in United Sated and Canada, and neoadjuvant chemotherapy followed by radical surgery is the first line of treatment in some institutions of Europe, Asia and Latin America. Until today, there is no evidence of which strategy is better over the other. This article describe the evidence as well as the advantages and disadvantages of the main strategies of treatment for women affected by uterine cervical cancer stage ⅠB2-ⅡB.展开更多

This paper focuses on a few of these biomarkers,namely microsatellite instability,loss of heterozygosity at chromosome 18q(LOH18q) and multi-gene assays,and discusses the clinical evidence behind their predictive or prognostic abilities. The results show that although there have been several newer prognostic factors identified,such as LOH18 q and multi-gene assays,none of these factors can predict benefit from treatment. Therefore,ongoing prospective clinical trials are still needed to further assess the role and optimal use of these tests.展开更多

The purpose of this study was to analyze prognostic factors associated with survival in a group of patients who underwent radical resection of stages Ⅱ and Ⅲ CRC.Methods A retrospective review was performed for 141 consecutive stages Ⅱ and Ⅲ patients who had undergone radical resection of coloractal adenocarcinoma between May 2003 and November 2003. Univariate and multivariate analyses were performed to assess the effect of record variables on disease free survival and overall survival.Results The median follow-up time was 59 months, and the 3-and 5-year survival rates were 76% and 68%,respectively. Four factors were independently associated with a worse disease-free survival： diabetes （hazard ratio （HR） 2.338; 95% confidence interval （CI） 1.011-5.407）, expression of cyclooxygenase-2 （Cox-2） （HR 0.335; 95% CI 0.126-0.888）, expression of matrix metalloproteinases 2 （MMP-2） （FIR 0.233; 95% CI 0.101-0.541）, expression of vascular endothelial growth factor （VEGF） （HR 0.295; 95% CI 0.088-0.996）. Four factors were independently associated with a worse overall survival： lymph nodes metastasis （HR 1.67; 95% CI 1.29-2.14）, Cox-2 positive （HR 0.056; 95% CI 0.247-0.731）, MMP-2 positive （HR 0.398; 95% CI 0.190-0.836）, VEGF （HR 0.364; 95% CI 0.090-0.716）.Conclusions Diabetes, expression of Cox-2, MMP-2 and VEGF were independently associated with a worse diseasefree survival. Lymph nodes metastasis, expression of Cox-2, MMP-2 and high level of VEGF predicted a poor overall survival.展开更多
