Background and Aim: Increasing evidence correlates the presence of systemic inflammation with poor survival in patients with hepatocellular carcinoma (HCC). The aim of this study was to investigate the prognostic significance of the blood neutrophil-to-lymphocyte ratio (NLR) in patients with advanced HCC who received sorafenib monotherapy. Methods: A total of sixty-five patients with advanced HCC, not eligible for locoregional therapy, treated with sorafenib were enrolled. Potential prognostic factors such as age, gender, tumoral characteristics, performance status and NLR were analyzed. Results: Median OS and TTP for the entire cohort were 10.0 months (95%CI, 7.6-12.3 months) and 4.5 months (95% CI, 4.0-4.9 months). The mean NLR at baseline was 2.89. The median OS of patients with a high NLR (>4) was 6.5 months (95%CI, 5.2-7.7 months) compared with 12.5 months (95%CI, 9.9-15.0) for patients with a normal NLR (${\leq}4$) (P=0.01). Age ${\leq}65$, NLR>4, extrahepatic metastases and vascular invasion were all predictors of poorer overall survival. Multivariate analysis showed that NLR > 4, vascular invasion and extrahepatic metastases were independent predictors of poorer overall survival. The median TTP of patients with a high NLR was 2.5 months (95%CI, 1.4-3.6 months) compared with 4.5 months (95%CI, 3.9-5.1 months) for patients with a normal NLR (P=0.012). Conclusions: High baseline NLR was associated with worse OS and TTP for patients with advanced HCC treated with sorafenib.

Purpose: Stage-IIIC colon cancer is an advanced disease; however, its oncologic outcomes and prognostic factors remain unclear. In this study, we aimed to determine the predictors of disease-free survival (DFS) in patients with stage-IIIC colon cancer. Methods: From a multicenter database, we retrospectively enrolled 611 patients (355 men and 256 women) who had undergone a potentially curative resection for a stage-IIIC colon adenocarcinoma between 2003 and 2011. The primary endpoint was the 5-year DFS. Results: The median age was 62 years; 213 and 398 patients had right-sided colon cancer (RCC) and left-sided colon cancer (LCC), respectively. The 5-year DFS in all patients was 52.0%; median follow-up time was 35 months (range, 1-134 months). A multivariate Cox regression revealed that female sex (hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.19-1.90; P < 0.01), right-sided tumor location (HR, 1.65; 95% CI, 1.29-2.11; P < 0.01), lymphatic invasion (HR, 1.52; 95% CI, 1.08-2.15; P < 0.01) and a high (${\geq}0.4$) metastatic lymph node ratio (HR, 3.72; 95% CI, 2.63-5.24; P < 0.01) were independent predictors of worse 5-year DFS. Female patients with RCC were 1.79 fold more likely to experience recurrence than male patients with LCC. Conclusion: Female sex and right-sided tumor location are associated with higher tumor recurrence rates in patients with stage-IIIC colon cancers. Aggressive treatment and close surveillance should be planned for patients in these groups.
Background: Recently, several studies have reported that elevated platelet counts may be associated with the poor prognosis of colorectal cancer. However, conclusions remain controversial. This meta-analysis was therefore designed to analyze and evaluate the prognostic role of preoperative or pretreatment thrombocytosis in patients with colorectal cancer. Materials and Methods: We searched PubMed, EMBASE, the Cochrane Library and Web of Science to March 29th, 2015. The citation lists of included studies were also hand-searched to identify further relevant trials. To investigate the association between thrombocytosis and prognosis of colorectal cancer, the 1-year, 3-year and 5-year survival of each studies were obtained. The odds ratio (OR) with its 95% confidence interval (CI) was used to evaluate the relation of overall survival (OS) between thrombocytosis and normal platelet counts (PLT). Likewise, disease free survival (DFS) was obtained and evaluated. The analysis was performed and assessed using Review Manager 5.2. Results: A total of 14 studies (N=5,566 participants, 11 including 4,468 for OS, 6 including 1,533 for DFS) were included in this meta-analysis, of which seven (N=3810) defined thrombocytosis as a platelet count ${\geq}400{\times}10^9/L$, and 375 (9.8%) patients exhibited pretreatment thrombocytosis. Thrombocytosis have a close relationship with the poor OS of colorectal cancer compared with normal PLT, with the pooled ORs of 1-year, 3-year and 5-year survival being 0.41 [95% CI 0.34-0.51; P<0.001], 0.28 [95% CI 0.21-0.38; P<0.001] and 0.26 [95% CI 0.20-0.34; P<0.001], respectively. For DFS, the same results were showed as the pooled ORs of 1-year, 3-year and 5-year survival respectively being 0.34 [95% CI 0.24-0.50; P<0.001], 0.31 [95% CI 0.23-0.43; P<0.001] and 0.25 [95% CI 0.18-0.34; P<0.001]. Conclusions: This meta-analysis indicated that thrombocytosis may predict poor prognosis for patients with colorectal cancer, and platelet counts may be a cost-effective and noninvasive marker.
Background: Hepatocellular carcinoma (HCC) is a common and aggressive malignancy. Despite of the improvements in its treatment, HCC prognosis remains poor due to its recurrence after resection. This study provides complete genetic profile for Egyptian HCC. Genome-wide analyses were performed to identify the predictive signatures. Patients and Methods: Liver tissue was collected from 31 patients with diagnosis of HCC and gene expression levels in the tumours and their adjacent non-neoplastic tissues samples were studied by analyzing changes by microarray then correlate these with the clinico-pathological parameters. Genes were validated in an independent set by qPCR. The genomic profile was associated with genetic disorders and cancer focused on gene expression, cell cycle and cell death. Molecular profile analysis revealed cell cycle progression and arrest at G2/M, but progression to mitosis; unregulated DNA damage check-points, and apoptosis. Result: Nine hundred fifty eight transcripts out of the 25,000 studied cDNAs were differentially expressed; 503 were up-regulated and 455 were down-regulated. A total of 19 pathways were up-regulated through 27 genes and 13 pathways were down-regulated through 19 genes. Thirty-seven genes showed significant differences in their expression between HCC cases with high and low Alpha Feto Protein ($AFP{\geq}600$ IU/ml). The validation for the microarray was done by real time PCR assay in which PPP3CA, ATG-5, BACE genes showed down-regulation and ABCG2, RXRA, ELOVL2, CXR3 genes showed up-regulation. cDNA microarrays showed that among the major upregulated genes in HCC are sets. Conclusion: The identified genes could provide a panel of new diagnostic and prognostic aids for HCC.
Purpose: A positive esophageal margin is encountered in a total gastrectomy not infrequently. The aim of this retrospective review was to evaluate whether a positive esophageal margin predisposes a patient to loco-regional recurrence and whether it has an independent impact on long-term survival. Materials and Methods: A retrospective review of 224 total gastrectomies for adenocarcinomas was undertaken. The Chisquare test was used to determine the statistical significance of differences, and the Kaplan-Meier method was used to calculate survival rates. Significant differences in the survival rates were assessed using the log-rank test, and independent prognostic significance was evaluated using the Cox regression method. Results: The prevalence of esophageal margin involvement was $3.6\%$ (8/224). Univariate analysis showed that advanced stage (stage III/IV), tumor size ($\geq$5 cm), tumor site (whole or upper one-third of the stomach), macroscopic type (Borrmann type 4), esophageal invasion, esophageal margin involvement, lymphatic invasion, and venous invasion affected survival. Multivariate analysis demonstrated that TNM stage, venous invasion, and esophageal margin involvement were the only significant factors influencing the prognosis. All patients with a positive esophageal margin died with metastasis before local recurrence became a problem. A macroscopic proximal distance of more than 6 cm of esophagus was needed to be free of tumors, excluding one exceptional case which involved 15 cm of esophagus. Conclusion: All of the patients with a positive proximal resection margin after a total gastrectomy had advanced disease with a poor prognosis, but they were not predisposed to anastomotic recurrence. Early detection and extended, but reasonable, surgical resection of curable lesions are mandatory to improve the prognosis.
Background: Overexpression or amplification of human epidermal growth factor receptor-2 (HER2) is associated with grade of malignancy and a poor prognosis in breast cancer (BC). The aim of this study was to evaluate of value of HER2 as a prognostic marker, and to analyze associations with common histopathological parameters in BC cases. Materials and Methods: Between of 2007 to 2014, 260 patients with BC referred to Oncology Clinic provided cancer tissue samples which underwent immunohistochemistry (IHC) for markers. ER and PR positivity was defined as ${\geq}10%$ positive tumor cells with nuclear staining. HER2-positive was defined as either HER2 gene amplification by fluorescent in situ hybridization (FISH) or scored as 3+ by IHC. For HER2 (2+), FISH was performed to determine HER2 positivity. Results: The mean age at diagnosis for the patients with HER2-negative was significantly higher than in HER2-positive cases. Also, there were significant correlations between histological grade, nuclear grade, lymph node metastasis, tumor size, ER status, PR status, p53 overexpression and Ki-67 index with HER2 expression. HER2-negative lesions were of higher grade and more likely to be ER-negative, PR-negative, p53-positive, lymph node metastasis, with a tumor size<2cm and also $Ki-67{\geq}20%$ as compared to the HER2-positive group. Conclusions: Contrary to the results of other studies, HER2-positive tumors in our study had a lower Ki-67 index and were p53-positive. Also, Ki-67 proliferation index ${\geq}20%$ in more studies was associated with p53-positive.Therefore, tumors which are HER2-positive and have a Ki-$67{\geq}20%$ had a more aggressive behavior compared to HER2-positive and Ki-67<20% lesions.
Background: Increasing evidence suggests that stromal monocarboxylate transporter 4 (MCT4) and carbonic anhydrase IX (CA IX) may play key roles in tumor development. However, their clinical value remains largely unexplored in gastric cancer (GC). The present study aimed to determine clinicopathological significance and prognostic values of stromal MCT4 and CA IX in GC. Materials and Methods: Specimens from 143 GC patients were immunohistochemically stained using polyclonal anti-MCT4 and anti-CA IX antibodies. Expression was correlated with patient clinicopathologic characteristics and survival data. Results: High stromal MCT4 expression was detected in 72 of 143 (50.3%) GCs and high CA IX in 74 (51.7%). Both high stromal MCT4 and CA IX were correlated with advanced TNM stage (p=0.000; p=0.000). High CA IX expression was positively related to depth of invasion (p=0.022) and positive lymph nodes (p=0.002) as well. Survival analysis indicated high expression of stromal MCT4 to be an independent factor in predicting poor overall survival (OS) (HR and 95%CI=1.962, 1.032-3.729, p=0.040) and disease free survival (DFS) (HR and 95%CI=2.081, 1.158-3.741, p=0.014) of GC patients. However, high CA IX expression exhibited no significant predictive value. Conclusions: These findings suggest that high expression of stromal MCT4 and CA IX proteins is significantly correlated with GC progression. High stromal MCT4 heralds worse outcome of GC patient, suggesting a novel candidate prognostic marker and therapeutic target.

Purpose: In this study, we investigated the clinical features and prognostic factors of early-onset sepsis (EOS) in neonatal intensive care unit (NICU) patients. Methods: A retrospective analysis was conducted on medical records from January 2010 to June 2017 (7.5 years) of a university hospital NICU. Results: There were 45 cases of EOS (1.2%) in 3,862 infants. The most common pathogen responsible for EOS was group B Streptococcus (GBS), implicated in 10 cases (22.2%), followed by Escherichia coli, implicated in 9 cases (20%). The frequency of gram-positive sepsis was higher in term than in preterm infants, whereas the rate of gram-negative infection was higher in preterm than in term infants (P<0.05). The overall mortality was 37.8% (17 of 45), and 47% of deaths occurred within the first 3 days of infection. There were significant differences in terms of gestational age (26.8 weeks vs. 35.1 weeks) and birth weight (957 g vs. 2,520 g) between the death and survival groups. After adjustments based on the difference in gestational age and birth weight between the 2 groups, gram-negative pathogens (odds ratio [OR], 42; 95% confidence interval [CI], 1.4-1,281.8) and some clinical findings, such as neutropenia (OR, 46; 95% CI, 1.3-1,628.7) and decreased activity (OR, 34; 95% CI, 1.8-633.4), were found to be associated with fatality. Conclusion: The common pathogens found to be responsible for EOS in NICU patients are GBS and E. coli. Gram-negative bacterial infections, decreased activity in the early phase of infection, and neutropenia were associated with poor outcomes.
Objective : The purpose of this study was to describe the clinical characteristics, treatment outcomes, and prognostic factors in patients with brain abscesses treated in a single institute during a recent 10-year period. Methods : Fifty-one patients with brain abscesses who underwent navigation-assisted abscess aspiration with antibiotic treatment were included in this study. Variable parameters were collected from the patients' medical records and radiological data. A comparison was made between patients with favorable [Glasgow Outcome Scale (GOS) ${\geq}4$] and unfavorable (GOS <4) outcomes at discharge. Additionally, we investigated the factors influencing the duration of antibiotic administration. Results : The study included 41 male and 10 female patients with a mean age of 53 years. At admission, 42 patients (82%) showed either clear or mildly disturbed consciousness (GCS ${\geq}13$) and 24 patients (47%) had predisposing factors. The offending microorganisms were identified in 25 patients (49%), and Streptococcus species were the most commonly isolated bacteria (27%). The mean duration of antibiotic administration was 42 days. At discharge, 41 patients had a favorable outcome and 10 had an unfavorable outcome including 8 deaths. The decreased level of consciousness (GCS <13) on admission was likely associated with an unfavorable outcome (p=0.052), and initial hyperglycemia (${\geq}140mg/dL$) was an independent risk factor for prolonged antibiotic therapy (p=0.032). Conclusion : We found that the level of consciousness at admission was associated with treatment outcomes in patients with brain abscesses. Furthermore, initial hyperglycemia was closely related to the long-term use of antibiotic agents.
Background : Although patients with stage IV non-small cell lung cancer are known to have a poor prognosis, the prognostic factors for survival have not been well evaluated. Such factors may be different from those for overall survival. This study was performed to analyze the prognostic factors for survuval and the variation of survival according to metastatic organ, in patients with stage IV non-small cell lung cancer. Materials and Methods : From January 1997 to December 2000, 151 patients with confirmed stage IV non-small cell lung cancer were enrolled into this study retrospectively. The clinical and laboratory data were analyzed using univareate Kaplan-Meied and Multivariate Cox regression models. Results : On univariate analysis, age, performance status, serum albumin level, weight loss, forced expiratory volume in one second (FEV1), systemic chemotherapy, the number of metastatic organs and serum lactate dehydrogenase (LDH) level were significant factors (p<0.05). In multivariate analysis, important factors for survival were ECOG performance (relative risk of death [RR]: 2.709), systemic chemotherapy (RR: 1.944), serum LDH level (RR: 1.819) and FEV1 (RR: 1.774) (p<0.05), Metastasis to the brain and liver was also a significant factor on univariate analysis). The presence of single lung metastasis was associated with better survival than that of other metastatic organs (p=0.000). Conclusion : We confirmed that performance status and systemic chemotherapy were independent prognostic factors, as has been recognized. The survival of stage IV non-small cell lung cancer patients was different according to the metastatic organs. Among the metastatic sites, only patients with metastasis to the lung showed bettrer survival than that of other sites, while metastasis of the brain or liver was associated with worse survival than that of other sites.
