Meta-analysis:prognostic value of survivin in patients with pancreatic cancer

Objective： The aim of the study was to conduct a systematic review of the literature evaluating survivin expres- sion in pancreatic carcinoma as a prognostic indicator. Methods： The relevant literatures were searched using PubMed, EMBASE, and Chinese Biomedicine Databases. A meta-analysis of the association between survivin expression and overall survival in patients with pancreatic cancer was performed. Studies were pooled and summary hazard ratios （HRs） were calculated. Subgroup analysis according to the location of survivin expression was also performed. Results： Seven eligible studies with a total of 448 patients were included in this study. Combined HR suggested that survivin expression had an unfavorable impact on survival of pancreatic cancer patients （HR = 1.65, 95% CI： 1.02-2.68）. When stratified according to the location of survivin expression, the combined HR showed that expression in the cytoplasm was significantly associated with poor prog- nosis of pancreatic cancer patients （HR = 2.09, 95% CI： 1.29-3.40）. In contrast, survivin expression in the nucleus was not significantly associated with poor prognosis （HR = 0.83, 95% CI： 0.24-2.81）, and the heterogeneity was highly significant （I2 = 87.2%, P = 0.005）. Conclusien： Survivin expression was associated with a poor prognosis in patients with pancreatic cancer. Cytoplasmic expression of survivin may be a prognostic factor for pancreatic cancer patients. Based on the current obtained data, there was no evidence that survivin expression in the nucleus had a significant impact on patients＇ overall survival.     

Prognostic significance of ERCC1 expression in postoperative patients with gastric cancer

Aim： This study explored the correlation between the expression of excision repair cross-complementation group 1 （ERCC1） and the prognosis of gastric cancer patients. Methods： From January 2005 to December 2008, 605 patients who underwent radical surgery in The First Affiliated Hospital of Nanjing Medical University were enrolled. We conducted the follow-up every 6 months and its contents included a comprehensive medical history, tumor markers and abdominal ultrasound or CT and other imaging findings. Deadline was April 30, 2013 and follow-up time between 51 to 91 months. Survival time is calculated from the date of diagnosis to death or last follow-up date. Immunohistochemistry （IHC） was used to assess the expression of ERCCI in resected samples. The relationship between ERCCI expression and survival of patients was investigated. The comparison of count data were analyzed by Chi-square test. Median survival time （MST） and the 5-year survival rate were calculated by life table analysis. The Kaplan-Meier curves were used for survival analysis. Results： ERCC1 expression was positive in 412 patients （68.1%）. There is no significant difference between ERCCl-positive group and ERCCl-negative group in terms of the MST and 5-year survival rate （P=0.455）. The MST and 5-year survival rate have no significant difference （P=0.162） between group with chemotherapy and group with no chemotherapy in patients with ERCCl-positive expression. However, the MST and 5-year survival rate in patients with ERCCl-negative expression benefited more from with chemotherapy （P=0.019）. The ERCCl-positive patients survived longer than those ERCCl-negative patients （P=0.183） in subgroup with no adjuvant chemotherapy. In the subgroup analysis, ERCC 1 expression had no significant relationship with overall survival in patients with stage II or llI gastric cancer （P〉0.05）. Conclusions： ERCC1 might be a good prognostic factor for the patients of gastric cancer after radical resection. Patients with ERCC     

Operable Breast Cancer： a Clinical Analysis of 6,263 Cases

OBJECTIVE In Europe and America breast cancer commonly occurs in women of middle and old age, with a median age of about 57 years. Modified radical mastectomy now called standard radical mastectomy, has taken the place of traditional radical mastectomy. Patients with breast cancer at an early stage commonly receive BCT (breast conservative therapy). The TNM stage (especially the lymph node status) affects the prognosis, and adjuvant therapy can improve survival. In China, only a few reports have been pubIished studying large numbers of breast cancer patients. This study was designed to analyze the clinical features, surgical pattern and treatment outcome of resectable breast cancer, as well as to explore the prognostic factors and the effect of adjuvant therapy, with a goal to improve the level of diagnosis and treatment.METHODS Records of the 6,263 patients with resectable breast cancer who had been admitted into our hospital from June 1964 to June 2003 were analyzed retrospectively.RESULTS Of the 6,263 cases, 98.8% were female. Breast cancer occurred most frequently in patients of ages 40～49 years (41.0%), especially in patients 45～49 years old (25.2%). A breast lump, which occurred in 96.2% of the patients, was the main clinical manifestation. The overall 5- and 10-year survival rates were 75.16% and 40.44%. Of the patients in TNM stages 0-1,Ⅱ, and Ⅲ, the 5-year survival rates were 96.8%, 73.7% and 46.4% respectively and the 10-year survival rates were 78.7%, 64.6% and 33.5% respectively. The 5-, and 10-year survival rates were higher in the lymph node negative group than in the lymph node positive group (80.3% vs. 55.6%, and 59.2% vs. 31.9%, P＜0.01). Since the 1980s there was no significant difference in survival rates of patients who received a radical mastectomy compared to a modified radical mastectomy(P＞0.05). Of the 73 patients who underwent breast conservative therapy, no local recurrence or metastasis occurred during a maximal follow-up of 17 years. Of the patients in stage T2T4, the 5-, and 10-year survival rates were significantly higher in the group treated with adjuvant chemotherapy compared to the non-chemotherapy group (78.2% vs. 60.1%, and 48.9% vs. 30.7%, P＜0.01).CONCLUSION According to our data, breast cancer most frequently occurred in patients of ages 45～49 years. The TNM stage (especially the lymph node status) relates to breast cancer prognosis. The prognosis was worse in patients with positive lymph nodes compared to the patients with negative lymph nodes. The efficacy of a modified radical mastectomy is equal to that of a radical mastectomy, and breast conservative therapy can be applied to patients in an early stage. Adjuvant chemotherapy and endocrine therapy can improve the survival of resectable breast cancer patients.     

Expression of Bmi-1,P16,and CD44v6 in Uterine Cervical Carcinoma and Its Clinical Significance

Objective Bmi-1,a putative proto-oncogene,is a core member of the polycomb gene family,which is expressed in many human tumors.The pl6 protein negatively regulated cell proliferation,whereas CD44v6 is associated with proliferation as an important protein.Additionally,CD44v6 is an important nuclear antigen closely correlated to tumor metastasis.The present study aims to investigate the expression and significance of Bmi-1,pl6,and CD44v6 in uterine cervical carcinoma(UCC). Methods A total of 62 UCC,30 cervical neoplasic,and 20 normal cervical mucosal tissues were used in the current study.The expression of Bmi-1,pl6,and CD44v6 in these tissues was determined using immunohistochemical assay.The relationships among the expression of these indices,the clinicopathologic features of UCC,and the survival rate of UCC patients were also discussed.The correlation between Bmi-1 protein expression and pl6 or CD44v6 protein in UCC was analyzed. Results The expression of Bmi-1,p16,and CD44v6 was significantly high in cervical carcinoma compared with that in the cervical neoplasia and normal colorectal mucosa(P<0.05).The over-expression of Bmi-1 protein in UCC was apparently related to the distant metastasis(P<0.01) and the tumor,nodes and metastasis-classification,i.e.the TNM staging,World Health Organization(P<0.05). Nevertheless,the positive expression of pl6 protein in UCC was not significantly associated with the clinicopathologic features (P>0.05).The Kaplan-Meier survival analysis showed that the over-expression of Bmi-1 significantly decreased the survival rate of UCC patients(P<0.05).A strong correlation indicated that there was statistical significance between the expression of Bmi-1 and CD44V6 proteins in UCC(r=0.419,P<0.001). Conclusions The over-expression of Bmi-1 and CD44v6 protein closely correlate to the tumorigenesis,metastasis,and prognosis of UCC.Bmi-1 and CD44v6 may be used to predict the prognosis of cervical carcinoma.Bmi-1 may indirectly regulate the expression of CD44v6 in UCC patients.The positive expression of p16 protein is possibly associated with the tumorigenesis,but not with the metastasis or prognosis of UCC.     

Studies of Selective Arterial Perfusion plus Chemoembolization on Hepatic Metastasis from Rectal Cancer

OBJECTIVE To develop an effectual method for treating hepatic metas-tasis from rectal cancer. METHODS A randomized control study of celiac artery perfusion plus transcatheter hepatic arterial chemoembolization (TACE) (observation group) and intravenous chemotherapy (control group) for 99 cases with hepatic me-tastasis from rectal cancer was performed. The perfusion was repeated once at 4 weeks after the first treatment of 52 cases in the observation group, and it was subsequently repeated at an interval of 2 or 3 months. Using intrave-nous administration, the perfusion was repeated once every 3 weeks with 47 cases in the control group. RESULTS Three months after treatment, the patients in the observation group who showed a relief or elimination of a former superior abdominal pain amounted to 70.6%, and those with a diminution of their intrahepatic mass reached 55.8%. In the control group, the patients with a relief or disappear-ance of hepatalgia reached 20%, and those with a diminution of their intrahe-patic mass reached 10.6%. The 1, 2 and 3-year survival rates were 80.8%, 46.2% and 25.0% in the cases of the observation group and 61.7%, 19.1% and 4.3% in the control group, respectively. CONCLUSION For the patients who failed to receive a surgical opera-tion on their hepatic metastasis from rectal cancer, celiac artery perfusion plus TACE is a more effective regimen for improvement of the clinical symp-toms and extension of the survival time, compared to intravenous chemo-therapy, and is a better choice for palliative therapy.     

Investigation of the Effect of Neoadjuvant Chemotherapy on Stage Ⅱ Breast Cancer

OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage Ⅱ breast cancer. METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage Ⅱ,during the period of 1995 to 2001,were analyzed retrospectively.Among the patients,47 were treated with neoadjuvant chemotherapy,and 66 received no adjuvant therapy before surgery（control group）.After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen,the surgical procedure was conducted. RESULTS Complete remission（CR）was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission（PR）was reached for 22 cases.The rate of breast-conserving surgery was enhanced from 22.73%to 46.81%（P〈0.05）in the neoadjuvant treatment group. There was no difference in the 5-year overall survival（OS）and disease-free survival（DFS）rate between the two groups（P〉0.05）,but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group（P〈0.05）. CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage Ⅱ breast cancer and may improve the prognosis of the cases with clinical remission.     

肺癌患者外周血血小板活化标志物水平及其临床意义

Objective： To investigate the relationship between the activation markers of platelets and the lung cancer. Methods： Based on international stages of lung cancer in 1997, lung cancer patients of 120 cases diagnosed by pathology as well as with operation indication were selected as the experimental group. During the process of experiment, 60 cases concluded as healthy in the physical examination were chosen as control group. The activation markers of platelets were detected by FCM method. The experimental result would be processed by SPSS 11.5. Results： The level of activation markers of platelets in peripheral blood of lung cancer patients was significantly higher than those healthy people （P 〈 0.01）. The level of activation markers of platelets in peripheral blood of lung cancer patients on the seventh postoperative day was significantly lower than that before operation and on the first postoperative day （P 〈 0.01）. The level of activation markers of platelets in peripheral blood of lung cancer patients was closely related to the size of the primary tumor, lymph node status and stages, but not to the grade of cell differentiation, type of tumor, age, sex of the patients （P 〉 0.05）. Conclusion： Elevation of the level of activation markers of platelets in peripheral blood exists in lung cancer patients and the levels of activation marker of platelets plays an important role in tumor growth and lymphatic metastasis. The levels of activation markers of platelets maybe a predictor for prognosis.     

The mid-long term outcome of breast-conserving patients with different ages

OBJECTIVE Breast-conserving surgery has been a standard treatment for relatively small size of breast cancer. Younger breast cancer patients have more desire to conserve their breasts. This study was to investigate the clinicopathological characteristics and prognosis of younger breast cancer patients who received breastconserving treatment in China. METHODS The data of 232 breast cancer patients who received breast-conserving treatment in Cancer Hospital of Chinese Academy of Medical Science from January Ist, 1999 to December 31st, 2005, were collected and retrospectively analyzed. According to the age, the patients were divided into 2 groups： younger group （age ≤ 35 at the time of diagnosis） and elder group （age 〉35）. The clinical features of the patients in the 2 groups were compared, and their clinical characteristics, recurrence, metastasis and survival status were summarized. RESULTS In the 232 cases, younger patients accounted for 15.9% （37/232）, the elder 84.1% （195/232）. By December 2008, the median time of follow-up was 54 months （ranging from 2 months to 118 months）. Two patients （5.41% , 2/37） in the younger group and 5 patients （2.56% 5/195） in the elder group died. The 5-year overall survival rate （OS） in the younger and elder groups was 96.08% and 97.19%, respectively （X2= 0.69, P = 0.4066）. Local recurrence （LR） or distant metastasis （DM） presented in 5 patients （5/37, 13.51%） in younger group. LR or DM presented in 10 patients （10/195, 5.13%） in elder group. The 5-year disease-free survival （DFS） rate in the younger and elder groups was 82.58% and 95.52%, respectively （X2 = 4.02, P = 0.0451）. Lymph node status and the age of 35 years old or younger were the prognosis factors affecting the DFS of patients who received breast-conserving treatment （OR = 3.467, 95%CI： 1.048-11.472, P 〈0.05; OR = 0.245, 95%CI： 0.069-0.863, P 〈 0.05）. Lymph node status was the only prognostic factor affecting the DFS of younger group patients （OR = 7.357, 95%CI： 1.030-52.563, P 〈0.05）. CONCLUSION Though the younger and elder patients have the same mid-long term survival rate, younger patients are more likely to have recurrence or metastasis than the elder patients. Breast-conserving surgery given to the younger patients especially to the younger patients with lymph nodes positive should be contemplated cautiously.     

Over-expression of metastasis-associated in colon cancer-1 (MACC1) associates with better prognosis of gastric cancer patients

Objective: The aim of this study was to detect metastasis-associated in colon cancer-1 (MACC1) expression in Chinese gastric cancer and analyze the relationship between MACC1 expression and postoperative survival. Methods: The expression of MACC1 and c-MET protein in a sample of 128 gastric cancer tissues was detected by immunohistochemistry. A retrospective cohort study on the prognosis was carried out and data were collected from medical records. Results: The positive rate of MACC1 protein expression in gastric cancer was 47.66%, higher than that in adjacent noncancerous mucosa (P<0.001). MACC1 protein expression was not related to the clinicopathological variables involved. Kaplan-Meier analysis revealed that the survival of MACC1 positive group tended to be better than that of MACC1 negative group, particularly in patients with stage III carcinoma (P=0.032). Cox regression analysis revealed that MACC1 protein over-expression in gastric cancer tended to be a protective factor with hazard ratio of 0.621 (P=0.057). Immunohistochemical analysis showed that the positive rate of c-MET protein expression was much higher in cases with positive MACC1 expression in gastric cancer (P=0.002), but P53 expression was not associated with MACC1 expression. Conclusion: MACC1 over-expression implies better survival and may be an independent prognostic factor for gastric cancer in Chinese patients.
