Background: Systemic inflammatory response was shown to play an important role in development and progression of many cancer types and different inflammation-based indices were used for determining prognosis. We aimed to investigate the prognostic effects of neutrophil to lymphocyte ratio (NLR) and prognostic nutritional index (PNI) in patients with non-small cell lung cancer (NSCLC). Materials and Methods: NSCLC patients diagnosed in our institution were retrospectively reviewed. Demographic and clinicopathologic characteristics were recorded. NLR and PNI was calculated before the application of any treatment. Results: A total of 138 patients were included in the study. Patients were divided into two groups according to NLR (<3.24 or ${\geq}3.24$) and PNI (<49.5 or ${\geq}49.5$). While median overall survival was 37.0 (95% CI 17.5-56.5) months in the group with low NLR, it was calculated as 10.0 (95%CI 5.0-15.0) months in the group with high NLR (p<0.0001). While median overall survival was 7.0 (95%CI 3.5-10.5) months in the group with low PNI, it was calculated as 33.0 (95% CI 15.5-50.4) months in the group with high PNI (p<0.0001). Stage, NLR and PNI levels were evaluated as independent risk factors for overall survival for all patients in multivariate analysis (p<0.0001, p=0.04 and p<0.001, respectively). Conclusions: NLR (${\geq}3.24$) and PNI (<49.5) at diagnosis is an independent marker of poor outcome in patients with NSCLC. NLR and PNI is an easily measured, reproducible prognostic tests that could be considered in NSCLC patients.

Background: Breast cancer is the most common malignancy with the highest incidence rates among women worldwide. Triple-negative breast cancer (TNBC) disease is diagnosed more frequently in younger women, and is associated with a poor prognosis. Elevated levels of serum haptoglobin protein (Hp) are observed in many malignant diseases including breast cancer. We evaluated the expression and prognostic value of Hp among patients with TNBC. Materials and Methods: Serum Hp levels were determined by Elisa in 41 patients with TNBC and 10 normal individuals. Hp status was correlated with other clinico-pathological parameters including patient survival. Results: Of the 41 patients with TNBC, Hp over expression was detected in 24 (59%) by Elisa. Hp up-regulation was confirmed by Elisa based quantification in the serum of 41 TNBC patients against lower grades and 10 normal individuals. Survival analysis revealed that Hp ($p=2.016{\times}10^{-5}$), stage ($p=2.166{\times}10^{-5}$), distant metastasis ($p=2.217{\times}10^{-5}$), tumor size ($p=1.053{\times}10^{-5}$), and tumor grade (p=0.001), correlated with patient survival on univariate analysis. Multivariate analysis revealed that Hp (p=0.001), and grade of the disease (p=0.008) were independent predictors of survival. Conclusion: Our results indicate that serum levels of Hp may play a role as a potential serum biomarker and prognostic indicator among TNBC patients. Thus, Hp may present a new promising prognostic biomarker in TNBC patients, but independent validations are now necessary for confirmation.

Background: Hepatitis B virus (HBV) infection has been reported to be associated with inferior prognosis in hepatocellular and pancreatic carcinoma cases, but has not been studied with respect to non small cell lung cancer (NSCLC). The purpose of this study was to investigate the prognostic significance of HBV infection in advanced NSCLC patients. Materials and Methods: A retrospective cohort of 445 advanced NSCLC patients was recruited at our hospital from January 1, 2003 until August 30, 2014. Serum HBV markers were tested by enzyme-linked immunosorbent assay. COX proportional hazards analysis was used to evaluate associations of HBV infection with overall survival (OS). Results: Of 445 patients who were qualified for the study, 68 patients were positive for HBsAg, also considered as HBV infection. Patients in HBsAg negative group were found to have better OS (12.6 months [12.2-12.9]) than those in HBsAg positive group (11.30 months [10.8-11.9]; p=0.001). Furthermore, COX multivariate analysis identified HBV infection as an independent prognostic factor for OS (HR 0.740 [0.560, 0.978], p=0.034). Conclusions: Our study found that HBsAg-positive status was an independent prognostic factor for OS in patients with advanced NSCLC. Future prospective studies are required to confirm our findings.

Purpose: The diagnosis of pelvic fractures pattern has become to be essential in the decision making of treatment modality and reducing morbidity and mortality in multiple trauma patients. Sacroiliac joint (SIJ) disruption can cause life-threatening massive arterial bleeding. This study aimed to determine a method of predicting the prognosis and treatment direction with pelvis X-ray alone in the emergency room. We investigated whether SIJ disruption can be used alone as a poor prognostic factor. Methods: We analyzed the medical records and radiologic examination results of 167 patients with pelvic fractures from January 1, 2015 to December 31, 2016 retrospectively. Patients with pathologic fractures, thoraco-abdominal bleeding, and acetabulum fractures and pediatric patients (n=63) were excluded. Factors related to the clinical manifestations and treatments, such as transfusion and surgery, were statistically compared. Results: The cross-sectional analysis showed that there was no correlation between SIJ injury and sex; there were statistically significant relationships between occurrences of shock, conjoined fractures, transfusion, and surgeries. The hospitalization period and partial thromboplastin time and prothrombin time values increased. The logistic regression analysis showed that when an SIJ injury occurred, blood transfusion and hypotension possibilities increased. Conclusions: When pelvic fractures occur near the SIJ, blood transfusion and shock possibilities increase. Physicians must be aware of the high severity and poor prognosis of such fractures when these are diagnosed in the emergency room. And furthermore, the physician has to predict and prepare the intensive care and multidisciplinary approaches.

Background: The number of patients with oral cancer in India is increasing gradually (especially in younger people). Although the diagnostic modalities and therapeutic management of oral cancer are improving, the treatment outcome and prognosis of oral cancer remain poor. The absence of definite early warning symptoms for most head and neck cancers suggests that sensitive and specific biomarkers are likely to be important in screening for high-risk patients. Aims: To analyze serum adenosine deaminase (ADA) levels in oral squamous cell carcinoma (OSCC) cases who reported to our institute. Materials and Methods: A prospective study was performed on 100 histopathologically proven cases of OSCC (study group) and 100 normal healthy individuals (control group). Independent sample and one sample t-tests and one way ANOVA followed by Tuckey's POST HOC test were conducted for analysis. Results: Statistically significant increase in serum ADA levels was observed in OSCC cases compared to the control group. Also serum ADA level increased significantly with the histopathological grade. Conclusions: Serum ADA levels in OSCC may be a useful diagnostic and prognostic biomarkers in clinical practice and our findings suggest that a large-scale study is warranted to confirm clinical utility as a prognostic and diagnostic biomarker.

The purpose of this study was to evaluate the association of expression of ${\alpha}5{\beta}1$-integrin with clinicopathologic features and prognosis in cervical cancer. Levels of ${\alpha}5{\beta}1$-integrin in normal cervical mucosa and cervical cancer tissue were detected with immunohistochemistry. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance. ${\alpha}5{\beta}1$-integrin expression was detected in 84.6% (143/169) cervical cancer samples, significantly different from that in normal cervical mucosa (P < 0.05). Positive expression rates of ${\alpha}5{\beta}1$-integrin in patients with poor histologic differentiation, lymph node metastasis, and recurrence were elevated. Using Kaplan-Meier analysis, a comparison of survival curves of low versus high expression of ${\alpha}5{\beta}1$-integrin revealed a highly significant difference in human cervical cancer cases (P < 0.05), suggesting that overexpression of ${\alpha}5{\beta}1$-integrin is associated with a worse prognosis.The ${\alpha}5{\beta}1$-integrin promotes angiogenesis and associates with lymph node metastasis, vascular invasion and poor prognosis of cervical cancer. The current study indicated that ${\alpha}5{\beta}1$-integrin may be an independent prognostic factor for cervical cancer patients.

Cancer of the stomach is the second most frequent cancer-related death worldwide. The survival rate of patients with gastric cancer (GC) remains fragile. There is a requirement to discover biomarkers for prognosis approaches. Helicobacter pylori in the stomach is closely associated with the progression of GC. We identified the genes associated with poor/favorable prognosis in H. pylori-induced GC. Multivariate statistical analysis was applied on the Gene Expression Omnibus (GEO) dataset GSE54397 to identify differentially expressed miRNAs (DEMs) in gastric tissues with H. pylori-induced cancer compared with the H. pylori-positive with non-cancerous tissue. A protein interaction map (PIM) was built and subjected to DEMs targets. The enriched pathways and biological processes within the PIM were identified based on substantial clusters. Thereafter, the most critical genes in the PIM were illustrated, and their prognostic impact in GC was investigated. Considering p-value less than 0.01 and |Log2 fold change| as >1, five microRNAs demonstrated significant changes among the two groups. Gene functional analysis revealed that the ubiquitination system, neddylation pathway, and ciliary process are primarily involved in H. pylori-induced GC. Survival analysis illustrated that the overexpression of DOCK4, GNAS, CTGF, TGF-b1, ESR1, SELE, TIMP3, SMARCE1, and TXNIP was associated with poor prognosis, while increased MRPS5 expression was related to a favorable prognosis in GC patients. DOCK4, GNAS, CTGF, TGF-b1, ESR1, SELE, TIMP3, SMARCE1, TXNIP, and MRPS5 may be considered prognostic biomarkers for H. pylori-induced GC. However, experimental validation is necessary in the future.

Purpose: The liver is one of the most commonly injured organs in abdominal trauma. Surgery has played a major role in treating traumatic liver injury. Recently, it was reported that conservative treatment could be the first-line management for hemodynamically stable patients without combined intraabdominal surgical problems. The aim of this study was to examine the prognostic factors in traumatic liver injury. Methods: The medical records of 41 patients who were treated for traumatic liver injury at Seoul National University Bundang Hospital from March 2003 to October 2007 were retrospectively reviewed. Results: Among the 41 patients, 34 cases (82.9%) were managed nonsurgically, and 7 cases (17.1%) were managed surgically. Out of the 5 (12.2%) mortalities, 2 were encountered in those who underwent surgery, and 3 were encountered in those who were treated nonsurgically. Univariate analysis showed that the initial systolic blood pressure, the initial hemoglobin level, and the grade of liver injury were significant prognostic factors for survival. Multivariate analysis indicated that initial low systolic blood pressure was the only independent risk factor. Conclusion: Patients with unstable vital signs initially have a poor prognosis. Aggressive management might be helpful for improving the survival rate in these patients.

Objective : The incidence of primary CNS lymphoma(PCNSL) has been increasing recently. The purpose of this study is to establish of prognostic factors and treatment options for PCNSL. Methods : Thirty-one PCNSL patients were treated in our institute between 1985 and 1997. All patients were histologically confirmed via stereotactic biopsy or open biopsy. The authors retrospectively analyzed clinical characteristics of PCNSL and prognostic factors, including histological cell types, immunohistological cell types and treatment options of PCNSL. Our data were statistically analyzed using Kaplan Meier survival curve and multivariated ANOVA test. Results : The clinical and radiological characteristics of PCNSL were resembled to those of other reports. The most common histological subtype was diffuse large cell type(55.5%). In immunohistolgical study, the incidence of T-cell lymphoma(35.7%) was very higher than that of others. The radiotherapy could prolonged patients' survival(p=0.021). One-year and 3-year survival rate of PCNSL were 66.9% and 45.9%, respectively. One-year survival rate of B cell and T cell lymphoma were 72.7% and 50.0%, respectively. The patients with B-cell lymphoma showed better prognosis than patients with T-cell lymphoma(p=0.049). Conclusion : On the basis of our data, active radiotherapy could prolong patients' survival. the T-cell lymphoma revealed higher incidence than those of other reports and had poor prognosis than that of B cell lymphoma.
