| 1 | Hepatocellular carcinoma surveillance:An evidence-based approach显示文摘Hepatocellular carcinoma(HCC) makes up 75%-85% of all primary liver cancers and is the fourth most common cause of cancer related death worldwide. Chronic liver disease is the most significant risk factor for HCC with 80%-90% of new cases occurring in the background of cirrhosis. Studies have shown that early diagnosis of HCC through surveillance programs improve prognosis and availability of curative therapies. All patients with cirrhosis and high-risk hepatitis B patients are at risk for HCC and should undergo surveillance. The recommended surveillance modality is abdominal ultrasound(US) given that it is cost effective and noninvasive with good sensitivity. However, US is limited in obese patients and those with non-alcoholic fatty liver disease(NAFLD). With the current obesity epidemic and rise in the prevalence of NAFLD, abdominal computed tomography or magnetic resonance imaging may be indicated as the primary screening modality in these patients. The addition of alpha-fetoprotein to a surveillance regimen is thought to improve the sensitivity of HCC detection.Further investigation of serum biomarkers is needed. Semiannual screening is the suggested surveillance interval. Surveillance for HCC is underutilized and low adherence disproportionately affects certain demographics such as nonCaucasian race and low socioeconomic status. | Patrick S Harris Ross M Hansen Meagan E Gray Omar I Massoud Brendan M McGuire Mohamed G Shoreibah | 2019 | World Journal of Gastroenterology2019，25，13： | 31 |
| 2 | Hepatocellular carcinoma: Review of disease and tumor biomarkers显示文摘Hepatocellular carcinoma(HCC) is a common malignancy and now the second commonest global cause of cancer death. HCC tumorigenesis is relatively silent and patients experience late symptomatic presentation. As the option for curative treatments is limited to early stage cancers, diagnosis in non-symptomatic individuals is crucial. International guidelines advise regular surveillance of high-risk populations but the current tools lack sufficient sensitivity for early stage tumors on the background of a cirrhotic nodular liver. A number of novel biomarkers have now been suggested in the literature, which may reinforce the current surveillance methods. In addition, recent metabonomic and proteomic discoveries have established specific metabolite expressions in HCC, according to Warburg's phenomenon of altered energy metabolism. With clinical validation, a simple and non-invasive test from the serum or urine may be performed to diagnose HCC, particularly benefiting low resource regions where the burden of HCC is highest. | Jin Un Kim Mohamed I F Shariff Mary M E Crossey Maria Gomez-Romero Elaine Holmes I Jane Cox Haddy K S Fye Ramou Njie Simon D Taylor-Robinson | 2016 | World Journal of Hepatology2016，8，10： | 13 |
| 3 | Real time endoscopic ultrasound elastography and strain ratio in the diagnosis of solid pancreatic lesions显示文摘AIM To evaluate the accuracy of the elastography score combined to the strain ratio in the diagnosis of solid pancreatic lesions(SPL). METHODS A total of 172 patients with SPL identified by endoscopic ultrasound were enrolled in the study to evaluate the efficacy of elastography and strain ratio in differentiating malignant from benign lesions. The semi quantitative score of elastography was represented by the strain ratio method. Two areas were selected, area(A) representing the region of interest and area(B) representing the normal area. Area(B) was then divided by area(A). Sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV), and accuracy were calculated by comparing diagnoses made by elastography, strain ratio and final diagnoses.RESULTS SPL were shown to be benign in 49 patients and malignant in 123 patients. Elastography alone had a sensitivity of 99%, a specificity of 63%, and an accuracy of 88%, a PPV of 87% and an NPV of 96%. The best cut-off level of strain ratio to obtain the maximal area under the curve was 7.8 with a sensitivity of 92%, specificity of 77%, PPV of 91%, NPV of 80% and an accuracy of 88%. Another estimated cut off strain ratio level of 3.8 had a higher sensitivity of 99% and NPV of 96%, but with less specificity, PPV and accuracy 53%, 84% and 86%, respectively. Adding both elastography to strain ratio resulted in a sensitivity of 98%, specificity of 77%, PPV of 91%, NPV of 95% and accuracy of 92% for the diagnosis of SPL. CONCLUSION Combining elastography to strain ratio increases the accuracy of the differentiation of benign from malignant SPL. | Hussein Okasha Shaimaa Elkholy Ramy El-Sayed Mohamed-Naguib Wifi Mohamed El-Nady Walid El-Nabawi Waleed A El-Dayem Mohamed I Radwan Ali Farag Yahya El-sherif Emad Al-Gemeie Ahmed Salman Mohamed El-Sherbiny Ahmed El-Mazny Reem E Mahdy | 2017 | World Journal of Gastroenterology2017，23，32： | 11 |
| 4 | Viral hepatitis prevalence in patients with active and latent tuberculosis显示文摘AIM: To assess the prevalence of hepatitis B virus(HBV) and hepatitis C virus(HCV) infection and association with drug induced liver injury(DILI) in patients undergoing anti-tuberculosis(TB) therapy.METHODS: Four hundred and twenty nine patients with newly diagnosed TB- either active disease or latent infection- who were due to commence antiTB therapy between September 2008 and May 2011 were included. These patients were prospectively tested for serological markers of HBV, HCV and human immunodeficiency virus(HIV) infections- hepatitis B core antigen(HBc Ag), hepatitis B surface antigen(HBs Ag), hepatitis B e antigen, Ig G and Ig M antibody to HBc Ag(anti-HBc), HCV Ig G antibody and HIV antibody using a combination of enzyme-linked immunosorbent assay, Western blot assay and polymerase chain reaction techniques. Patients were reviewed at least monthly during the TB treatment initiation phase. Liver function tests were measured prior to commencement of antiTB therapy and 2-4 wk later. Liver function tests were also performed at any time the patient had significant nausea, vomiting, rash, or felt non-specifically unwell. Fisher's exact test was used to measure significance in comparisons of proportions between groups. A P value of less than 0.05 was considered statistically significant.RESULTS: Of the 429 patients, 270(62.9%) had active TB disease and 159(37.1%) had latent TB infection. 61(14.2%) patients had isolated anti-HBc positivity, 11(2.6%) were also HBs Ag positive and 7(1.6%) were HCV-antibody positive. 16/270 patients with active TB disease compared to 2/159 patients with latent TB infection had markers of chronic viral hepatitis(HBs Ag or HCV antibody positive; P = 0.023). Similarly the proportion of HBs Ag positive patients were significantly greater in the active vs latent TB infection group(10/43 vs 1/29, P = 0.04). The prevalence of chronic HBV or HCV was significantly higher than the estimated United Kingdom prevalence of 0.3% for each. We found no association between DILI and presence of serological markers of HBV or HCV. Three(5.3%) patients with serological markers of HBV or HCV infection had DILI compared to 25(9.5%) patients without; P = 0.04.CONCLUSION: Viral hepatitis screening should be considered in TB patients. DILI risk was not increased in patients with HBV/HCV. | Hesam Ahmadi Nooredinvand David W Connell Mahmoud Asgheddi Mohammed Abdullah Marie O'Donoghue Louise Campbell Melissa I Wickremasinghe Ajit Lalvani Onn Min Kon Shahid A Khan | 2015 | World Journal of Gastroenterology2015，21，29： | 7 |
| 5 | The oncofetal protein IMP3 is an indicator of early recurrence and poor outcome in mucoepidermoid carcinoma of salivary glands显示文摘Objective: Mucoepidermoid carcinoma(MEC) is the most common primary malignancy of the salivary glands. Insulin-like growth factor-II m RNA-binding protein-3(IMP3) is an important prognostic factor in some cancers and a tool that differentiates between benign and malignant pancreatic lesions. This study aimed to identify a relationship between the expression of IMP3 and the outcome of salivary gland MEC, as well as to differentiate MEC from pleomorphic adenoma(PA).Methods: Tissue specimens from 70 cases of salivary gland MEC, 40 cases of PA, and 10 cases with normal salivary gland were examined immunohistochemically for IMP3. The association among the expression of IMP3, clinicopathological characteristics and patient's survival was assessed.Results: IMP3 was present in 51.4% of MEC but absent in PA and normal salivary gland tissues. IMP3 expression was associated with age > 60 years, submandibular gland tumors, tumor size > 4 cm, high-grade tumors, lymph node metastasis, involvement of surgical margins, perineural invasion, distant metastasis, advanced TNM stage, tumor relapse, and death(P<0.05). Increased expression of IMP3, tumors of the submandibular gland, and lymph node metastasis were independent prognostic factors of disease-free survival(DFS). In addition, IMP3 was a strong predictor of overall survival(OS) together with distant metastasis and intermediate and high-grade tumors.Conclusions: IMP3 expression is highly important in evaluating the outcome of MEC. IMP3 can be used to differentiate MEC from PA of salivary glands. | Mohamed R.Elshafey Rehab A.Ahmed Mohamed I Mourad Essam T.Gaballah | 2016 | Cancer Biology & Medicine2016，13，2： | 5 |
| 6 | Annexin A2 as a biomarker for hepatocellular carcinoma in Egyptian patients显示文摘AIM To investigate the clinical utility of serum annexin A2(ANXA2) as a diagnostic marker for early hepatocellular carcinoma(HCC).METHODS This study was performed in HCC Clinic of Ain Shams University Hospitals, Cairo, Egypt and included: Group 1: Fifty patients with early stage HCC(Barcelona Clinic Liver Cancer stage A); Group 2: Twenty five patients with chronic liver disease; and Control Group: Fifteen healthy, age-and sex-matched subjects who were seronegative for viral hepatitis markers. The followinglaboratory investigations were done: Viral hepatitis markers [hepatitis B surface antigen and hepatitis C virus(HCV) antibodies], HCV RNA in HCV antibody-positive patients, serum alpha fetoprotein(AFP), and serum ANXA2 levels.RESULTS In this study, 88% of HCC patients(n = 44) were HCVpositive, while HBV infection represented only 8% of all HCC patients(n = 4); and two patients were negative for both viral markers. A highly significant difference was found between patients with HCC and chronic liver disease as well as controls with regard to serum ANXA2 levels(130, IQR 15-240; 15, IQR 15-17; and 17, IQR 15-30 ng/m L, respectively). The area under the curve of ANXA2 was 0.865; the cut-off value was established to be 18 ng/mL with a diagnostic sensitivity of 74% and a specificity of 88%, while the sensitivity and specificity of AFP at the cut-off value of 200 ng/dL were 20% and 100%, respectively.CONCLUSION Serum ANXA2 may serve as a biomarker for the early detection of HCC. | Mohamed K Shaker Hanzada I Abdel Fattah Ghada S Sabbour Iman F Montasser Sara M Abdelhakam Eman El Hadidy Rehab Yousry Ahmed K El Dorry | 2017 | World Journal of Hepatology2017，9，9： | 4 |
| 7 | Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases. | Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz | 2014 | The Journal of Biomedical Research2014，28，3： | 3 |
| 8 | Ascites and alpha-fetoprotein improve prognostic performance of Barcelona Clinic Liver Cancer staging显示文摘AIM: To assess how ascites and alpha-fetoprotein(AFP) added to the Barcelona Clinic Liver Cancer(BCLC) staging predict hepatocellular carcinoma survival.METHODS: The presence of underlying cirrhosis, ascites and encephalopathy, Child-Turcotte-Pugh(CTP) score, the number of nodules, and the maximum diameter of the largest nodule were determined at diagnosis for 1060 patients with hepatocellular carcinoma at a tertiary referral center for liver disease in Egypt. Demographic information, etiology of liver disease, and biochemical data(including serum bilirubin, albumin, international normalized ratio, alanine and aspartate aminotransferases, and AFP) were evaluated. Staging of the tumor was determined at the time of diagnosis using the BCLC staging system; 496 patients were stage A and 564 patients were stage B. Patients with mild ascites on initial ultrasound, computed tomography, or clinical examination, and who had a CTP score ≤ 9 were included in this analysis. All patients received therapy according to the recommended treatment based on the BCLC stage, and were monitored from the time of diagnosis to the date of death or date of data collection. The effect of the presence of ascites and AFP level on survival was analyzed.RESULTS:At the time the data were censored,123/496(24.8%)and 218/564(38.6%)patients with BCLC stages A and B,respectively,had died.Overall mean survival of the BCLC A and B patients during a three-year follow-up period was 31 mo[95%confidence interval(95%CI):29.7-32.3]and 22.7mo(95%CI:20.7-24.8),respectively.The presenceof ascites,multiple focal lesions,large tumor size,AFP level and CTP score were independent predictors of survival for the included patients on multivariate analysis(P<0.001).Among stage A patients,18%had ascites,33%had AFP≥200 ng/m L,and 8%had both.Their median survival in the presence of ascites was shorter if AFP was≥200 ng/m L(19 mo vs 24 mo),and in the absence of ascites,patients with AFP≥200 ng/m L had a shorter survival(28mo vs 39 mo).For stage B patients,survival for the corresponding groups was 12,18,19 and 22 mo.The one-,two-,and three-year survival rates for stage A patients without ascites and AFP<200 ng/m L were94%,77%,and 71%,respectively,and for patients with ascites and AFP≥200 ng/m L were 83%,24%,and 22%,respectively(P<0.001).Adding ascites and AFP≥200 ng/m L improved the discriminatory ability for predicting prognosis(area under the curve,0.618vs 0.579 for BCLC,P<0.001).CONCLUSION:Adding AFP and ascites to the BCLC staging classification can improve prognosis prediction for early and intermediate stages of hepatocellular carcinoma. | Asmaa I Gomaa Alzhraa Al-Khatib Wael Abdel-Razek Mohammed Saad Hashim Imam Waked | 2015 | World Journal of Gastroenterology2015，21，18： | 3 |
| 9 | Percutaneous aspiration and drainage with adjuvant medical therapy for treatment of hepatic hydatid cysts显示文摘AIM:To determine the efficacy and success of percutaneous aspiration irrigation and reaspiration(PAIR) in the management of hepatic hydatidosis.METHODS:Twenty-six patients with 32 hepatic hydatid cysts had PAIR.Twenty-two patients received at least 2 wk of drug therapy before the procedure was carried out to reduce the risk of recurrence from spillage during the procedure.The procedure was performed under local anesthesia with a 19-gauge 20 cm long needle,the cyst was punctured,cystic content(approximately 30 mL) was aspirated by a 12-14 F pigtail catheter and aspirated fluids were sent for analysis.Once the cyst was almost empty,two-thirds of the net amount of material aspirated was replaced by hypertonic saline and left in the cavity for about 30 min,with the catheter left in place for reaspiration of most of the fluid.When the amount of fluid drained was less than 10 mL per 24 h,the drainage catheter was removed.RESULTS:All 32 cysts showed evidence of immediate collapse after completion of the procedure,and before discharge from hospital,ultrasound examination showed fluid reaccumulation in all cysts.Serial follow-up showed a progressive decrease in the size and change in the appearance of cysts.To confirm the sterility of these cystic cavities,seven cysts were reaspirated on average 3 mo after the procedure.Investigations revealed no viable scolices.CONCLUSION:PAIR using hypertonic saline is very effective and safe with proper precautions. | Mohammed I Yasawy Abdelrahman E Mohammed Sammak Bassam Mohammed A Karawi Sohail Shariq | 2011 | World Journal of Gastroenterology2011，17，5： | 3 |
| 10 | Efficacy and safety of treatment of hepatitis C virus infection in renal transplant recipients显示文摘AIM: To assess the efficacy and safety of combinedpegylated interferon and ribavirin therapy in hepatitis C virus (HCV) infection in renal transplant recipients. METHODS: This is a retrospective chart review of post renal transplant patients who were positive for anti-HCV and HCV-RNA, and who have received treatment with combination of pegylated interferon and ribavirin between October 2003 and December 2008. Only patients with stable graft function and absence of evidence of cirrhosis and who received the therapy for continuous 48 wk were included. Nineteen patients (13 male and 6 female) were identified and included. The patient's complete blood count, liver and kidney prof ile, and cal- culated glomerular f iltration rate (GFR) were monitored every 6-8 wk while on treatment. HCV-RNA was tested at 12 wk for early virological response, at 48 wk for end of treatment response (ETR), and then retested at 24, and 48 wk after completion of therapy for sustained virological response (SVR). Liver biopsies were obtained before treatment from all patients and graft kidney biopsies were performed as required. RESULTS: Of the entire cohort, 9 patients (47.4%) showed an ETR and 8 had SVR (42.1%). Of the 8 patients with abnormal alanine aminotransferase (ALT) levels at baseline, 78.9% had their ALT normalized (including the virological non responders). ALT was normal in all responders at the end of therapy and at 24 wk post therapy (100%). Only one patient (5.3%) developed an increase in creatinine and decline in GFR from baseline towards the end of treatment. This patient's kidney biopsy revealed borderline rejection. There was no impact on response by HCV-genotype, initial HCV RNA load, age or sex of the patient or duration post transplant before commencement of therapy. All patients tolerated treatment in the same way as non-transplant with no unusual or increased occurrence of side effects. CONCLUSION: The combination of pegylated interferon and ribavirin is effective in suppressing HCV-RNA,with a low risk of graft rejection or failure in HCV infected renal transplant recipients. | Abdulrahman A Aljumah Mohamed A Saeed Ahmed I Al Flaiw Ibrahim H Al Traif Abduljaleel M Al Alwan Salem H Al Qurashi Ghormallah A Al Ghamdi Fayez F Al Hejaili Mohammed A Al Balwi Abdulla A Al Sayyari | 2012 | World Journal of Gastroenterology2012，18，1： | 2 |
