ABSTRACT
Objective@#To analyze the clinical efficacy of thalidomide combined with TP regimen (taxol+cisplatin) in treatment of advanced gastric cancer.@*Methods@#A total of 60 patients with advanced gastric cancer in the Affiliated Cancer Hospital of Zhengzhou University from February 2016 to March 2018 were enrolled. The patients were divided into two groups by using random number table method: the observation group (32 cases) taking thalidomide, oral administration 100 mg based on TP regimen before going to bed; the control group (28 cases) taking TP regimen chemotherapy only. Both groups received 75 mg/m2 doses of cisplatin, intravenous infusion, 25 mg/m2 per day, for 3 d. Paclitaxel dose was 150 mg/m2, intravenous infusion for 1 day, 3-week was one course, and the efficacy was evaluated after at least 2 course of treatment.@*Results@#The incidence of gastrointestinal adverse reactions including nausea and vomiting was 21.8% (7/32) in the observation group, and was 64.3% (18/28) in the control group, and the difference was statistically significant (χ 2 = 11.051, P = 0.001), but there were no statistically significant differences in the incidence of morning faint, constipation, bone marrow suppression, liver and kidney injury and other adverse reactions between the two groups (all P > 0.05). The effective rates in the observation group and the control group were 43.8% (14/32) and 39.3% (11/28), respectively, and the disease control rates in the observation group and the control group were 84.4% (27/32) and 78.6% (22/28), respectively. There were no significant differences in the effective rates and the disease control rates between the two groups (χ 2 = 0.122, P = 0.726; χ2 = 0.336, P = 0.562). The improvement and significant improvement rate of sleeping quality, pain, Eastern Cooperative Oncology Group (ECOG) score was 71.9% (23/32), 53.1% (17/32), 56.2% (18/32), respectively in the observation group, and 17.9% (5/28), 14.3% (4/28), 21.4% (6/28), respectively in the control group, and the difference between the two groups was statistically significant (all P < 0.05).@*Conclusions@#Thalidomide combined with TP regimen in treatment of advanced gastric cancer patients can improve the efficacy of chemotherapy and the quality of life. It also has a good tolerance to side effects.
ABSTRACT
Objective@#To investigate the role of microRNA-96-5p in the proliferation and invasion of gastric cancer cells and its molecular mechanism.@*Methods@#From June 2015 to January 2017, 53 resected specimens were collected. The transcriptional levels of microRNA-96-5p and forkhead box Q1 (FoxQ1) in gastric cancer tissues and the matched para-cancerous tissues were quantified by quantitative real-time PCR (qRT-PCR). The expression of FoxQ1 protein was also detected by immunohistochemistry (IHC). The relationship between microRNA-96-5p expression and the clinicopathological features of gastric cancer and its correlation with FoxQ1 expression were analyzed. The expressions of miRNA-96-5p in gastric cancer tissue and adjacent normal tissue were detected by qRT-PCR. miRNA-96-5p mimics was transfected to BGC-823 gastric cancer cells. The effects of miRNA-96-5p on cell proliferation and invasion were detected by cell counting kit-8 (CCK-8) assay and Transwell assay, respectively. The protein expressions of FoxQ1, E-cadherin and vimentin were determined by western blot. The relationship between FoxQ1 and miRNA-96-5p expressed in BGC-823 cells was detected by dual-luciferase reporter assay.@*Results@#The median expression of miRNA-96-5p in gastric cancer tissue was 1.05, significantly lower than 3.23 of para-cancerous tissues (P<0.05). The positive rate of FoxQ1 expression in gastric cancer tissue was 71.7%, significantly higher than 28.3% of para-cancerous tissues (P<0.05). The expression of FoxQ1 was negatively corelated with the level of miRNA-96-5p (r=-0.613, P=0.006). The expression of miRNA-96-5p in gastric cancer cell BGC-823 was significantly decreased compared with normal gastric epithelial cell (0.96±0.08 vs 2.84±0.15, P<0.05). The results of CCK-8 assay and Transwell assay showed that overexpression of miRNA-96-5p significantly reduced the proliferation and invasion abilities of gastric cancer cells (P<0.05). Overexpression of miRNA-96-5p decreased the protein level of FoxQ1. Moreover, it upregulated the expression of E-cadherin and downregulated the expression of vimentin. The result of dual-luciferase-3′-UTR reporter assay confirmed that miRNA-96-5p binds to the 3′UTR of FoxQ1.@*Conclusion@#miRNA-96-5p may suppress the proliferation, migration and epithelial-mesenchymal transition (EMT) of gastric cancer cell by down-regulation of FoxQ1.
ABSTRACT
Objective@#To explore the clinical characteristics, treatment strategy and prognosis of adenoid cystic carcinoma of the head and neck (ACCHN).@*Methods@#A retrospective analysis of the clinical and follow-up treatment of 79 patients with ACCHN from June 2008 to July 2017 was conducted in the Cancer Hospital of Zhengzhou University.@*Results@#A total of 79 ACCHN cases, including 31 males and 48 females. The age ranged from 19 to 77 (median, 52).

ABSTRACT
Objective@#To explore the clinical characteristics, surgical procedures and prognosis of solid pseudopapillary tumor of the pancreas(SPTP).@*Methods@#The clinical and follow-up data of 55 cases with SPTP in Henan Tumor Hospital from June 2005 to April 2015 were retrospectively analyzed.@*Results@#There were 55 SPTP cases, including 7 males and 48 females. The age ranged from 16 to 76 (median, 33). Clinical presentations of SPTP were not specific. The mean size of the tumor was 7.6 cm (range from 2 to 25cm). Pancreatic head and tail were the most common locations of SPTP. All the patients received surgical resection with a definitive pathological diagnosis. Some immunohistochemical markers were mostly positive, including β-catenin, Vim, Syn, CD10, CD56, PR, etc. With a median follow-up of 53 months, the 1-year, 2-year and 5-year survival rate were 98.1%, 96.1% and 94.0%, respectively.@*Conclusions@#SPTP is an uncommon exocrine pancreatic neoplasm with low malignant potential, which frequently occurs in young women. Preoperative imaging can provide evidence for the selection of treatment modalities among which surgical resection ispreferred. Diagnosis still relies on pathology and immunohistochemistry.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the prognostic impact of different chemotherapy strategies on small cell esophageal carcinoma (SCEC).</p><p><b>METHODS</b>The clinical data of 62 patients with histologically confirmed SCEC treated in our department between January 2006 and April 2011 were retrospectively analyzed. There were 39 patients with limited stage (LS) and 23 patients with extensive stage (ES) SCEC according to the Veterans Administration Lung Study Group staging system. Cox's hazard regression model was used to determine the prognostic factors, and Chi-square test was used to detect the difference of frequencies among different groups. Kaplan-Meier and log-rank analyses were used to estimate and compare the survival rates.</p><p><b>RESULTS</b>The chemotherapy combined with local therapy group was significantly better than chemotherapy alone group in median survival time (MST) (20.8 vs. 7.6 months, P<0.05). The MST was 18.0 months and the 1-, 2-, and 3-year overall survival rates (OS) were 68.8%, 38.6%, and 20.9%, respectively, for all the 62 patients. Etoposide plus cisplatin or carboplatin (EP/CP) did not result in significantly longer MST, compared with that of the cases treated by other combination chemotherapy (P>0.05, for either LS or ES cases). Multivariate analysis showed that the VALSG stage, the number of chemotherapy cycles (≥ 4), and treatment modality are independent prognostic factors (P<0.05).</p><p><b>CONCLUSIONS</b>SCEC is a tumor characterized by high malignancy and poor prognosis. Chemotherapy combined with local therapy is an effective treatment for SCEC, and appropriate chemotherapy cycles (≥ 4) may improve the survival time. EP/CP, as commonly used multidrug chemotherapy regimen, is not superior to other combination chemotherapy.</p>

Treatment methods include surgery, radiotherapy and chemotherapy. The overall result is poor.
ABSTRACT
Primary esophageal small cell carcinoma (PESCC) is a rare disease first described by McKeown in 1952. PESCC is characterized by high malignancy, distant metastasis, and poor prognosis. The incidence of PESCC has significantly increased world-wide in recent years. However, practice guidelines that concern the histological origin, clinical diagnosis methods, therapies, and prog-nosis of PESCC are still not well established because of the paucity of cases and lack of large prospective randomized research. This ar-ticle aims to outline recent advances in the clinical and therapeutic aspects of PESCC as well as review the different opinions concerned to better understand PESCC and solve clinical problems.
ABSTRACT
Background and purpose:The recurrence and metastasis of gastric cancer seriously affect survival in patients.SOX gene as a regulatory factor of the classical Wnt pathway, may play an important role in the process. This study was to explore the expression of stem cell marker SOX-2 and β-catenin in gastric cancer and to analyze the relationship with recurrence and metastasis after operation.Methods:Immunohistochemistry was used to detect the expression of SOX-2 and β-catenin in 71 tumor samples from 71 cases after surgery for gastric cancer. The correlation between SOX-2 and β-catenin expression and the clinicopathological characteristics of gastric cancer and disease-free survival was analyzed.Results:The SOX-2 protein expression was associated with metastasis, lymph node inifltration or differentiation (P=0.011,P=0.036,P=0.034) in the 71 gastric cancer, but not with gender, age or T stage. β-catenin expression was correlated with metastasis, lymph node invasion or T stage (P=0.025,P=0.014,P=0.026), but was not related to differentiation, gender or age. The survival analysis showed that SOX-2 and β-catenin expression was closely associated with prognosis of patients, and metastatic rate in positive expression was higher than that in negative expression.Conclusion:The expression of SOX-2 and β-catenin is associated with the development, recurrence, metastasis of gastric cancer and may be used as a useful prognostic parameter to predict overall survival.
ABSTRACT
Objective To investigate the expression of β-catenin and Oct-4 in colonal carcinoma and explore the relationship with recurrence and metastasis after operation. MethodsImmunohistochemical analysis was used to evaluate the expression of β-catenin and Oct-4.The correlation of β-catenin and Oct-4 expression with tumor cell differentiation,T stage,N stage and metastasis was analyzed.The gene expression of Oct-4 was examined by RT-PCR in 20 frozen tumor tissues and normal tissues adjacent to tumor.Results Thirty-five patients had metastasis. The positive rates of β-catenin and Oct-4 expression were significantly higher in metastasis group than in the non-metastasis group (65.71％ vs 31.11％,51.43 ％vs 13.33 ％,x2 =9.843,P =0.002,x2 =13.605,P =0.001).Expression of β-catenin and Oct-4 was not associated with differentiation,T stage or N stage.The positive expression rate of Oct-4 in colonal carcinoma tissues was significantly higher than that in normal tissues.Metastatic rates in patients with positive expression of β-catenin and Oct-4 was higher than that in negative expression.The survival analysis showed that time of metastasis was significantly different in two groups of patients (P ＜0.05).Conclusion The expression of β-catenin and Oct-4 in tumor tissues is related to metastasis of colonal cancer after surgery and might be used to predict metastasis of colonal cancer after operation.
ABSTRACT
Objective To compare the short-term efficacy and adverse effects of docetaxe or oxaliplatin combined with capecitabine in the treatment of late-staged gastric cancer in aged patients. Methods Eighty-two aged patients with late-staged gastric cancer were randomly divided into two groups,of which 38 patients were treated group) ,and 44 patients were treated with oxaliplatin (100 mg/m2 ivgtt on 1st day) and eapecitabine (2000 mg/1 cycle). Results There is no failure of follow-up. In the docetaxe group,the effective rate was 52.63% (20/38) and 54.55 % (24/44) for the docetaxe and oxaliplatin group,respectively (P>0.05). The median progression-free survival(PFS) in the docetaxe group (6.1 months) was similar to that in the oxaliplatin group (6.3 months) (P>0.05). Gastrointestinal response,myelosuppression and neurotoxicity (Ⅰ or Ⅱ level) were the most common ad-verse effects observed in both groups (P>0.05). No chemotherapy-related death was observed. Conclusions The short-term efficacy of decetaxe or oxaliplatin combined with capecitabine in the treatment of late-staged gastric cancer in aged patients is similar,and the adverse effects are all within tolerance limits.
