Background: Platinum-hased chemotherapy for advanced non-small cell lung cancer (NSCLC) is still considered the first choice, presenting a modest survival advantage. However, the patients eventually experience disease progression and require second-line therapy. While there are reliable predictors to identify patients receiving first-line chemotherapy, very little knowledge is available about the prognostic factors in patients who receive second-line treatments. The present study was therefore performed. Methods: We retrospectively reviewed 107 patients receiving second-line treatments from August 2002 to March 2012 in the Dicle University, School of Medicine, Department of Medical Oncology. Fourteen potential prognostic variables were chosen for analysis in this study. Univariate and multivariate analyses were conducted to identify prognostic factors associated with survival. Result: The results of univariate analysis for overall survival (OS) were identified to have prognostic significance: performance status (PS), stage, response to first-line chemotherapy response to second-line chemotherapy and number of metastasis. PS, diabetes mellitus (DM), response to first-line chemotherapy and response to second-line chemotherapy were identified to have prognostic significance for progression-free survival (PFS). Multivariate analysis showed that PS, response to first-line chemotherapy and response to second-line chemotherapy were considered independent prognostic factors for OS. Furthermore, PS and response to second-line chemotherapy were considered independent prognostic factors for PFS. Conclusion: In conclusion, PS, response to first and second-line chemotherapy were identified as important prognostic factors for OS in advanced NSCLC patients who were undergoing second-line palliative treatment. Furthermore, PS and response to second-line chemotherapy were considered independent prognostic factors for PFS. It may be concluded that these findings may facilitate pretreatment prediction of survival and can be used for selecting patients for the correct choice of treatment.
Background: Although mucinous adenocarcinoma has been recognized for a long time, whether it is associated with a poorer prognosis in colorectal cancer patients is still controversial. Many studies put emphasis on mucinous adenocarcinoma containing mucin component ${\geq}50%$. Only a few studies have analyzed cases with a mucin component <50%. Objectives: This study aimed to analyze the prognostic value of different mucin component proportions in patients with stage III rectal cancer. Materials and Methods: Clinical, pathological and follow-up data of 136 patients with the stage III rectal cancer were collected. Every variable was analyzed by univariate analysis, then multivariate analysis and survival analysis were further performed. Results: Univariate analysis showed pathologic T stage, lymphovascular invasion, and histological subtype were statistically significant for DFS. Pathologic T stage was significant for OS. Histological subtype and lymphovascular invasion were independent prognostic factors in multivariate analysis for DFS, and histological subtype was the only independent prognostic factor for OS. Survival curves showed the survival time of mucinous adenocarcinoma (MUC) was shorter than non-MUC (adenocarcinomas with a mucin component <50% and without mucin component). Conclusions: Histological subtype (tumor with different mucin component) was an independent prognostic factor for both DFS and OS. Patients with MUC had a worse prognosis than their non-MUC counterparts with stage III rectal carcinoma.

Background: Previous studies have pointed to many different prognostic factors for small cell lung cancer (SCLC) but diabetes mellitus (DM) has not been clearly or consistently identified as of prognostic value. The aim of this study was to investigate the prognostic significance of the characteristics of patients and clinical laboratory tests in SCLC. Specifically, we investigated that the impact of DM for survival in the patients receiving first-line etoposide plus cisplatin (EP) chemotherapy. Methods: We retrospectively reviewed 161 patients with SCLC with a focus on DM and other potential prognostic variables were chosen for univariate and multivariate analyses with respect to survival. Result: Among the sixteen variables of univariate analysis, five were identified to have prognostic significance: performance status (PS) (p<0.001), stage (p=0.001), DM (p=0.005), serum albumin (p<0.001) and hemoglobin levels (p=0.03). Multivariate analysis showed PS, stage and serum albumin level to be independent prognostic factors for survival (p=0.02, p=0.02 and p=0.009 respectively), but DM was not an independnet factor. Conclusion: In conclusion, PS, stage and serum albumin level were identified as important prognostic factors, while DM at the time of diagnosis of SCLC did not have prognostic importance for survival.

Background: The majority of patients with gastric cancer in developing countries present with advanced disease. Systemic chemotherapy therefore has limited impact on overall survival. Patients eligible for chemotherapy should be selected carefully. The aim of this study was to analyze prognostic factors for survival in advanced gastric cancer patients undergoing first-line palliative chemotherapy. Methods: We retrospectively reviewed 107 locally advanced or metastatic gastric cancer patients who were treated with docetaxel and cisplatin plus fluorouracil (DCF) as first-line treatment between June 2007 and August 2011. Twenty-eight potential prognostic variables were chosen for univariate and multivariate analyses. Results: Among the 28 variables of univariate analysis, nine variables were identified to have prognostic significance: performance status, histology, location of primary tumor, lung metastasis, peritoneum metastasis, ascites, hemoglobin, albumin, weight loss and bone metastasis. Multivariate analysis by Cox proportional hazard model, including nine prognostic significance factors evident in univariate analysis, revealed weight loss, histology, peritoneum metastasis, ascites and serum hemoglobin level to be independent variables. Conclusion: Performance status, weight loss, histology, peritoneum metastasis, ascites and serum hemoglobin level were identified as important prognostic factors in advanced gastric cancer patients. These findings may facilitate pretreatment prediction of survival and can be used for selecting patients for treatment.
Background: Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease. Despite of proper treatment and improving treatment regimens, HLH patients still show a fatal prognosis. Therefore the evaluation of prognostic factor is important and there are many studies about hyperbilirubinemia as a prognostic factor in HLH. So we studied the prognostic value of hyperbilirubinemia in HLH children. Methods: A retrospective analysis was performed about 33 patients who were diagnosed with HLH at Pusan National University Hospital and Yangsan Pusan University Hospital between January 2000 to December 2012. We reviewed the clinical characteristics, laboratory findings, and results of treatment to identify hyper-bilirubinemia as a prognostic factor in HLH patients. Results: The median age of patients at diagnosis was 32 months. Most of patients presented with fever, pale appearance, abdominal pain and jaundice. Forty-eight point five percentage of patients showed normal serum bilirubiln level (<2.0 mg/dL) and 51.5% showed hyperbilirubinemia (${\geq}2.0mg/dL$). In normal serum bilirubin group, 1 patient (6.3%) was relapsed and 1 patient (5.9%) was relapsed in hyperbilirubinemia group. In the hyperbilirubinemia group, the mortality was higher than the normal bilirubin group but, there was no statistical significance. Conclusion: As a prognostic factor serum bilirubin at diagnosis in HLH patients, there was no significant correlation between hyperbilirubinemia and poor outcome. But, our study has a limitation that the number of patients is too small and almost showed good prognosis.

Introduction: Recent studies have indicated that down-regulation of the suppressor of cytokine signaling-1 (SOCS-1) gene results in tumor formation and that SOCS-1 acts as a tumor suppressor gene. SOCS-1 has been also suggested to function as a tumor suppressor with colorectal cancer. Objectives: In the present study, we aimed to determine the association of SOCS-1 expression in colorectal cancer tissues with clinicopathologic characteristics immunohistochemically and also to identify its prognostic significance. Materials and Methods: SOCS-1 expression was studied immunohistochemically in 67 patients diagnosed with resected colorectal carcinomas and 30 control subjects. Results: SOCS-1 expression was found in 46.3% of tumor tissues and 46.7% of the control group. Statistical analyses did not establish any significant association between SOCS-1 expression and clinicopathologic characteristics. Also, no significant association with SOCS-1 expression was found using progression-free survival and overall survival analyses (p=0.326 and p=0.360, respectively). Conclusions: Our results show that SOCS-1 has no prognostic significance in colorectal cancer.
The aim of this study was to identify the expression of zinc finger E-box binding homeobox 1 (ZEB1), its prognostic significance, and correlation between ZEB1 and infiltrating immune cells in lung cancer. Correlation between ZEB1 and telomerase was also analyzed in different types of cancers. RNA sequencing analysis and survival rates of patients were confirmed by Gene Expression Profiling Interactive Analysis (GEPIA). The Kaplan-Meier plotter and PrognoScan databases were used to analyze the prognostic value of ZEB1 in various cancers. The Tumor IMmune Estimation Resource (TIMER) was used to determine the correlation between ZEB1 and infiltrating immune cells. Lower ZEB1 expression was lower in lung cancer and was related to poor prognosis in lung adenocarcinoma (LUAD). ZEB1 expression exhibited a significantly positive correlation with infiltration levels of immune cells in LUAD and lung squamous cell carcinoma. Furthermore, we found that the ZEB1 expression correlated with subunits of telomerase. Our findings suggest ZEB1 as a potential biomarker to be used for prognostic significance and tumor immunology in lung cancer. The correlation between the expression of ZEB1 and telomere-related gene will help in understand the cancer-promoting mechanisms.
Purpose: The most important prognostic factors in gastric cancer are depth of invasion and lymph node metastasis. Therefore, the prognosis for serosa and lymph node negative gastric cancer is favorable. However, there is no general agreement on the prognostic factors in this subset of patients. This study was undertaken to evaluate the prognostic significances of venous invasion (VI), lymphatic invasion (LI), and perineural invasion (NI) in T1 and T2 gastric cancer without lymph node involvement. Materials and Methods: We retrospectively evaluated 206 patients with T1 and T2, lymph node negative gastric cancer who underwent a curative resection from 1989 to 1993 at Kangnam St. Mary's Hospital, Seoul, Korea. The Chi-square 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 the Cox regression method was used to evaluate independent prognostic significance. Results: The rate of VI, LI and NI correlated well with the depth of tumor invasion. The rates of VI (+) for T1 vs T2 was $0\%\;vs\;5.1\%$, of LI (+) was $5.6\%\;vs\;26.8\%$, and of NI (+) was $1.6\%\;vs\;26.8\%$ in NI (+). There were 13 recurrent cases, 10 cases out of the 13 were T2 gastric cancers, and the recurrence rate was higher in LI (+) and NI (+) cases than in LI (-) and NI (-) cases. The 5-year survival rates were $93.4\%$ in LI (-) cases, $77.4\%$ in LI (+) cases, $92.5\%$ in NI (-) cases, $74\%$ in NI(+) cases, $95.9\%$ in LI (-) NI (-) cases, and $73.9\%$ in LI (+) NI (+) cases. Multivariate analysis demonstrated that simultaneous LI and NI was the only significant factor influencing the prognosis. Conclusion: These results suggest that simultaneous lymphatic and perineural invasion may be an independent prognostic factor in patients with T1 and T2 gastric cancer without lymph node metastasis.

Objectives : The purpose of this study was to evaluate the clinical prognostic factors affecting facial palsy in 98 idiopathic facial palsy patients who were hospitalized and treated in 2015, using retrospective statistical analysis. Methods : We investigated patients with idiopathic facial nerve palsy, admitted to a Korean medical hospital in 2015, and examined patients' variables and therapeutic variables. For analysis of clinical data, an independent sample t-test, analysis of variance (ANOVA), and simple regression analysis were performed using IBM SPSS version 24.0. Results : 1. The initial degree of facial palsy showed statistical significance with age. The older the age, the more severe the initial palsy. 2. Following treatment degree of facial palsy was statistically significant with age, hypertension, and fasting blood sugar (FBS). The higher the value, the slower the recovery from facial palsy. There was a statistical significance with the number of treatments in a Korean medical hospital. The more frequent the treatment, the faster the facial palsy recovery. 3. Degree of facial palsy after 12 months was statistically significant with age, hypertension, diabetes, FBS, and the initial severity of facial palsy. The higher the value, the slower the facial palsy recovery. 4. Sex, left or right sided palsy, alcohol consumption, smoking, history of facial palsy, season of onset, total number of treatments and bio chemistry (BC), complete blood cell count (CBC), urinalysis (UA) factors had no statistical significance with prognosis of facial palsy. Conclusion : Age, season of onset, hypertension, diabetes, FBS, initial severity of facial palsy, and the number of treatments at a Korean medical hospital showed statistical significance. The number of treatments at the Korean medical hospital positively correlated with facial palsy prognosis, and the others variables showed a negative correlation with facial palsy prognosis.
Purpose: The most important prognostic factors in gastric cancer is the depth of invasion of the primary tumor and lymph node metastasis. The nodal staging of the 5th edition of the Union Internationale Contrala Cancrums (UICC) TNM classification in 1997 was changed based on the number of metastatic lymph node. We attempted to evaluate the prognostic significance of N2 group metastasis in pT3pN1 gastric cancer patients by comparing two different nodal staging systems. Materials and Methods: A retrospective analysis was made for 352 gastric cancer patients who underwent curative resection, including D2 dissection, from 1991 to 1997 at Asan Medical Center. A clinicopathologic comparison between two groups by using a nodal staging systems was summarized into a table. Cumulative survival rates were calculated by using the Kaplan-Meier method. The difference between the two groups was evaluated by using the log rank test with SPSS 11.5 for Windows Results: There were no statistical differences in clinicopathologic factors. However, there was a significant difference in survival rate between the two groups (P=0.0009). This suggests that N2 group metastasis in pT3pN1 gastric cancer patients has a clinical significance for predicting prognosis. Conclusion: Our results suggest a possibility of prognostic significance of N2 group metastasis. Therefore, anatomical location of the lymph node should be described.
