ABSTRACT
PURPOSE: The microRNA-34 (miR-34) family is important in tumor regulation. This study aimed to investigate the association of circulating miR-34 family proteins with clinicopathological features and their prognostic value in triple-negative breast cancer (TNBC) patients. MATERIALS AND METHODS: In this cohort study, 173 TNBC patients admitted to First People's Hospital of Shunde from May 1, 2009 to April 30, 2013 were enrolled. Meanwhile, 75 age-matched healthy women volunteers were identified as healthy controls (HCs). We examined the expression of miR-34 family (miR-34a/b/c) proteins in plasma collected from TNBC patients before any treatment was performed and from age-matched HCs using qPCR methods. RESULTS: The expressions of miR-34a/34b/34c were significantly lower in TNBC patients than in HC (p<0.001, p=0.027, p<0.001, respectively). miR-34a was correlated with tumor grade (p=0.038), lymph node positive (p=0.027), distant metastasis (p=0.004), and surgery (p=0.023); miR-34b was correlated with lymph node positivity (p=0.027); and miR-34c was correlated with tumor grade (p=0.017) and distant metastasis (p<0.001). Kaplan-Meier curve analysis displayed low expression of miR-34a as associated with worse overall survival (OS) (p=0.011), as well as miR-34c low expression (p=0.002). In addition, univariate and multivariate Cox proportional hazards regression was performed, and low expression of miR-34c (p=0.011) was found to be an independent risk factor for OS, as well as tumor grade (p=0.013), lymph node positive (p=0.050), and distant metastasis (p=0.021). CONCLUSION: In conclusion, this study demonstrated reduced miR-34a/c expression is highly associated with tumor progression and indicated worse prognosis. Also, miR-34c was an independent risk factor for OS in TNBC patients.

Objective To study the therapeutic of anastomotic leakage in post-esophagogastrectomy. Meth-ods There were 18 cases of anastomotic leakage in 127 cases with cancer of the thoracic esophagus who underwent esophagectomy were retrospectively studied. There were ten cases had anastomotic leakage of 67 cases of esophagogas-trectomy from 1995 to 2001 (first phase),the intestines nutrition sustain treatment taked rice water,fish soup and broth, there were eight cases had anastomotic leakage of 60 cases of esophagogastrectomy from 2002 to 2007 (second phase) ,the intestines nutrition sustain treatment taked supportan,fresubin. Results There were six cases death of 10 cases of anastomotic leakage at first phase, and there was any not death in the second phase. Conclusion When anastomotic leakage of esophagogastreetomy,it can elevate the cure rate with early diagncsis and treatment and intes-tines nutrition sustain treatment choose by supportan or fresubin.
ABSTRACT
Objective To study the clinical function of different incision in sentinel lymph node(SLN)biopsy in breast cancer.Methods 40 patients were early-stage breast cancer who were performed breast-conserving surgery for SLN biopsy with different incisions were retrospectively analyzed during November 2003 to November 2007.Results (1)Transversely incision(cleavage lines)were 35 cases;(2)arc incision were 3 cases;(3)one incision were 2 cases.Among the 40 cases,there are 30 cases which were performed breast-conserving surgery because the SLN and tumor-margin were negative with the quick frozen section during the operation,the rest of the SLN who had the contains cancer had to be performed mastectomy surgery.Conclusion When breast cancer conserving surgery are performed,transversely incision is the best incision for SLN biopsy.
