Objective: To evaluate the impact of esophagectomy and palliative treatment on short term and long term quality of life (QL) in patients with esophageal cancer. Methods: 88 consective patients treated with radical esophagectomy or palliative treatment were scored by European organization of cancer research and treatment (EORTC), QLQ C30 measurement of QL before treatment and at regular intervals until death or 3 years after operation. The cases were divided into 3 groups and mean scores were obtained from each group. Patients surviving more than 2 years were classified as group 1, with group 2 surviving less than 2 years, and group 3 undergoing palliative treatment. Results: Baseline functional and symptomatic QL scores were similar before treatment in the first and second group, which were higher than scores from the third group. Six weeks after esophagectomy, patients reported worse functional, symptom and global QL scores than before treatment. In the first group, QL scores returned to preoperative level within 9 months. However, improved symptom of dysphagia the second group never regained their former QL scores apart from dysphagia improved after surgery. QL scores of the third group were similar to those of the second group after treatment. Conclusion: Esophagectomy might have a negative impact on patients QL. This effect was found to be transient in the first group but inreversible in the second group. It might seem reasonable for patients in late stage to be treated palliatively.

Objective To explore the clinical significance of expression of DcR3/TR6 gene in the tissue of cardiac cancer and its correlation with survivin gene expression, Methods Two-step immnaohistochemistry technology was adopted to detect the expression of TR6 and survivin gene in 66 cases of cardiac cancer, none of the patients received prior chemotherapy. Results The positive expression rate of TR6 and survivin genes in cardiac cancer was 54.5% and 62.1% , respectively. The expression of TR6 was correlated with histology type,clinical stage and lymph node metastasis of cardiac cancer ( P<0.05 ). The positive expression rate of TR6 in cases that cardiac cancer with survivin expressed was significant higher than those without surviving expressed (χ2=15.145, P<0.01 ). Conclusions The expres-sion of TR6 and survivin can be regarded as valuable indicators for the diagnosis and prognosis of cardiac cancer.

Objective To investigate the role of preoperative peripheral blood neutrophil to lymphocyte ratio (NLR),platelet to lymphocyte ratio (PLR),prognostic nutritional index (PNI) in the prognosis of patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after radical operation.Methods This is a retrospective study,involving 426 surgically resected hepatitis B related hepatocellular carcinoma cases in a single center from 2003 to 2012.Results Kaplan-Meier analysis showed patients in NLR ≤ 1.62 group achieve higher rate of recurrence-free and overall survival than that in the NLR ＞ 1.62 group,the difference was statistically significant (P ＜ 0.005);Also PNI ＞ 49.42 group showed higher rate of overall survival significantly than PNI≤49.42 group (P ＜ 0.005).The results of Cox regression multivariate analysis further suggested that both NLR ＞ 1.62 (HR 1.74,P =0.007) and PNI ≤49.42 (HR 0.70,P =0.021) were independent risk factors for overall survival,NLR ＞ 1.62 (HR 1.45,P =0.03) was also an independent risk factor for recurrence-free survival.Conclusion The preoperative NLR and PNI may be independent risk factors for prognosis of patients with HBV-related HCC after radical operation.

Objective To explore the application value of fractional anisotropy(FA)values of magnetic resonance diffusion tensor imaging(DTI)parameters in rat rat glioma grading.Methods Sixty-seven female Wistar rats were divided into the experi-mental group(n=57)and control group(n=10)according to the random number table method.All the surviving rats were exam-ined by 3.0T DTI at 1-2 weeks(22 cases)and 3-4 weeks(35 cases)after inoculation,and the FA values of the tumor were ob-tained and compared with the pathological results.Results Among 57 tumor-loading rats,there were 18 low-grade gliomas and 39 high-grade gliomas.DTI showed that the FA value of high-grade gliomas was higher than that of the low-grade glioma,the differ-ence was statistically significant[(0.167 ± 0.035)vs.(0.147 ± 0.015),t=2.34,P<0.05].Conclusion The FA value of DTI pa-rameters can provide accurate,reliable and noninvasive imaging information for preoperative glioma grading.
