  • In the present study, we investigated the effects of motesanib (AMG 706), a multikinase inhibitor alone and in combination with DuP-697, an irreversible selective inhibitor of COX-2, on cell proliferation, angiogenesis, and apoptosis induction in a human colorectal cancer cell line (HT29). Real time cell analysis (RTCA, Xcelligence system) was used to determine the effects on colorectal cancer cell proliferation. Apoptosis was assessed with annexin V staining and angiogenesis was determined with chorioallantoic membrane model. We found that motesanib alone exerted antiproliferative, antiangiogenic and apoptotic effects on HT29 colorectal cancer cells. Combination with DUP-697 increased the antiproliferative, antiangiogenic and apoptotic effects. Results of this study indicate that motesanib may be a good choice in treatment of colorectal tumors. In addition, the increased effects of combination of motesanib with DuP-697 raise the possibility of using lower doses of these drugs and therefore avoid/minimize the dose-dependent side effects generally observed.

  • Background: There is no consensus regarding the selection of treatment options for hepatocellular carcinoma (HCC) after initial transarterial chemoembolization (TACE). This meta-analysis aimed to explore the survival benefit of hepatic resection after initial TACE for the treatment of HCC. Materials and Methods: We searched three major databases to identify all relevant papers comparing the outcomes of hepatic resection after initial TACE versus TACE alone for the treatment of HCC. Hazard ratios (HRs) with 95% confidence intervals (95%CIs) were calculated to evaluate the survival benefit of hepatic resection after initial TACE over TACE alone. Results: Three of 2037 initially identified papers were included. All of them were cohort studies from Asia. There was a significantly better overall survival (OS) in patients undergoing hepatic resection after initial TACE than in those undergoing TACE alone (HR=0.63, 95%CI=0.52-0.76, P<0.00001). The heterogeneity among studies was not statistically significant (P=0.96; I2=0%). Conclusions: Hepatic resection could improve the OS of HCC patients treated with initial TACE. Further randomized controlled trials should be necessary to identify the target population for the sequential use of hepatic resection after initial TACE and to compare the outcomes between patients undergoing hepatic resection after initial TACE session versus those undergoing TACE alone.

  • Background and Objective: Protein expression in colon and rectal cancer (CRC) and paired normal tissues was examined by two-dimensional gel electrophoresis (2-DE) to identify differentially expressed proteins. Materials and Methods: Five fresh colorectal cancer and paired adjacent normal tissues were obtained and differentially expressed protein spots were determined using PDQuest software, with identification on the basis of MALDI-TOF mass spectra. Results: Compared with normal colorectal mucosa, protein abnormal expression of 65 spots varying more than 1.5 times were found in 2-DE gels from colorectal cancer samples (P<0.05); forty-two proteins were up-regulated and 23 were down-regulated; twelve protein spots were identified using mass spectrometry, of which 8 were up-regulated, includimng HSPB1and Annexin A4, while 4 were down-regulated, the results being consistent with Western blot findings. Conclusions: Two-dimensional electrophoresis reference maps for CRC tissues and adjacent normal mucosa (NMC) were established and 12 differentially expressed proteins were identified. Up-regulated HSPB1 and Annexin A4 may play many important roles in the pathogenesis of colorectal cancer.

  • Purpose: To investigate the efficacy and toxicity of a combination of gemcitabine with nedaplatin (GN) or cisplatin (GC) for patients with unresectable or recurrent esophagus squamous cell carcinoma. Methods: Gemcitabine was administered at 1 g/m2 intravenously on days 1 and 8; and nedaplatin or cisplatin were administered at 80 mg/m2 intravenously on day 1. We analyzed the response rate, overall survival time, progression-free survival time, and toxicity in 21 patients treated with GN and 27 patients treated with GC. Results: In patients treated with gemcitabine plus nedaplatin, the ORR was 47.6%, the median progression-free survival time was 4.1 months, and the median survival time was 9.3 months. In patients treated with gemcitabine plus cisplatin, the ORR was 48.2%, the median progression-free survival time was 3.9 months, and the median survival time was 9.1 months, respectively. There were no statistically significant differences in ORR, PFS and OS between the two groups. In both, the most commonly observed toxicities were thrombocytopenia and fatigue. Nausea and vomiting was more frequent in the GC group than in the GN group. Conclusion: Gemcitabine based chemotherapy was effective and tolerable for patients with unresectable or recurrent esophagus squamous cell carcinoma refractory to first line chemotherapy.

  • Background: Pretreatment serum p53 and epidermal growth factor receptor (EGFR) were assessed using enzyme-linked immunosorbent assay (ELISA) in patients with acute leukemia to analysis their roles in characterization of different subtypes of the disease. Materials and Methods: Serum samples from thirty two patients with acute myeloid leukemia (AML) and fourteen patients with acute lymphoid leukemia (ALL) were analysed, along with 24 from healthy individuals used as a control group. Results: The results demonstrated a significant increase of serum p53 and EGFR in patients with AML (p<0.0001) compared to the control group. Also, the results showed a significant increase of both markers in patients with ALL (p<0.05, p<0.0001 respectively). Sensitivities and specificities for these variables were 52% and 100% for p53, and 73.9%, 95.8% for EGFR. Serum p53 and EGFR could successfully differentiate between M4 and other AML subtypes, while these variables failed to discriminate among ALL subtypes. A positive significant correlation was noted between p53 and EGFR. Negative significant correlations were observed between these variables and both of hemoglobin (Hg) content and RBC count. Conclusions: Mutant p53 and EGFR are helpful serological markers for diagnosis of patients with AML or ALL and can aid in characterization of disease. Moreover, these markers may reflect carcinogenesis mechanisms.

  • Purpose: The purpose of this study is to examine the factors influencing symptom experience in patients with liver cirrhosis(LC). Method: A descriptive correlational study design was used. A convenience sample of 129 subjects was recruited from the gastroenterology department at two university hospitals in Seoul, Korea. Symptom experience in LC was measured with the instrument developed by the researcher based on Theory of Unpleasant Symptoms(Lenz et al, 1995) and the Child-Pugh Score, the Korean version of Profile of Mood States, and the Family Support Questionnaire were used to identify the factors influencing symptom experience. Results: The mean score of symptom experience was relatively low(M=41.67, SD= 24.71). Among individual symptoms, fatigue had the highest score in all dimensions. Fatigue, abdominal distension and/or peripheral edema, muscle cramps, dry mouth, and change in appearance were explored as symptoms needing management. In the regression analysis, symptom experience was found to be influenced significantly by anxiety/depression($R^2=.418$, p=.000) and the severity of LC(Child-Pugh Score)($R^2=.125$, p=.000). These variables explained 54.3% of the variance in symptom experience(F=63.607. p=.000). Conclusion: It suggests that nurses need to take into consideration psychological factor as well as physiological factor in symptom management for patients with LC.

  • Purpose: The aim of this study was to investigate the factors contributing to health-related quality of life (HRQOL) among patients with chronic hepatitis B (CHB). Methods: A cross-sectional, descriptive design was used. The sample included 114 patients in a gastroenterology outpatient department at one hospital located in G city. Data were collected using a structured questionnaire from June to December 2009. The collected data were analyzed using SPSS/WIN 15.0. Results: Health-related quality of life was most strongly related to age, sex, income, occupation, and the care provider. Old age, female gender, lower income, not having an occupation and having a non-medical person were associated with lower HRQOL ($R^2$=.03~.22, p=.041~<.001). Conclusion: CHB infection had a negative impact on HRQOL among the older, female gender, low socioeconomic status and not having medically knowledgeable care givers. Interventions beyond nursing care may be needed to improve the quality of health for patients with Chronic Hepatitis B.

  • Aim: The significance of the mucinous adenocarcinoma in TNM staging and prognosis for colorectal tumor patients is still controversial. The aim was to provide a meta-analysis for TNM staging and prognostic features of colorectal tumors. Methods: 30 individual case-control studies were finally included into this meta-analysis, involving a total of 444,489 cancer cases and 45,050 mucinous adenocarcinomas, of relations with TNM staging and prognostic features. Results: Compared to non-mucinous adenocarcinoma patients, the TNM IV stage accounted for a larger percentage of mucinous adenocarcinomas (OR=1.48, 95%CI 1.28-1.71, POR<0.001) and the prognosis was significantly poor (HR=1.06, 95%CI 1.04-1.08, P<0.001). After heterogeneity testing, the results was similar to the holistic approach outcome (HR=1.48, 95%CI 1.35-1.62, P<0.001). Conclusion: Compared to patients with non-mucinous adenocarcinomas, mucinous adenocarcinoma patients with later TNM staging make up a big percentage, and mucinous adenocarcinoma is an independent risk factor for poor prognosis.

  • Pain caused by chronic pancreatitis is medically intractable and resistant to conventional interventional or surgical treatment. We report a case of spinal cord stimulation (SCS) for intractable pain due to chronic pancreatitis. The patient had a history of nonalcoholic chronic pancreatitis and multiple emergency room visits as well as repeated hospitalization including multiple nerve block and morphine injection for 3 years. We implanted surgical lead at T6-8 level on this patient after successful trial of percutaneous electrode. The patient experienced a decreased visual analog scale (VAS) scores for pain intensity and amount of opioid intake. The patient was followed for more than 14 months with good outcome and no further hospitalization. From our clinical case, spinal cord stimulation on intractable pain due to chronic pancreatitis revealed moderate pain control outcome. We suggest that SCS is an effective, noninvasive treatment option for abdominal visceral pain. Further studies and long term follow-up are needed to fully understand the effect of SCS on abdominal visceral pain.

  • Background: The role of processed meat in the aetiology of squamous cell oesophageal cancer has been explored in detail. Methods: In the time period 1990-2005, a case-control study was conducted in Montevideo, Uruguay including 2,368 participants (876 cases of oesophageal cancer and 1,492 controls). Relative risks, approximated by the odds ratios, were estimated by multiple unconditional logistic regression. Results: Processed meat was positively associated with oesophageal cancer (upper quartile vs lower quartile OR 2.30, 95%CI 1.72-3.07), whereas salted meat intake was positively associated with squamous cell oesophageal cancer (OR 3.82, 95%CI 2.74-5.33). Finally other cured meats were positively associated with oesophageal cancer (OR 1.65, 95%CI 1.22-2.22). Conclusions: It could be concluded that processed meat consumption could be an important risk factor for the aetiology of squamous cell oesophageal cancer in Uruguay.
