The Effect of Neoadjuvant Chemotherapy on Locally Advanced Gastric Cancer

Gastric Cancer

The aim of this study is to evaluate survival benefit of a neoadjuvant chemotherapy regimen in patient with resectable locally advanced gastric cancer in comparison with surgery alone.

Vestibular Schwannoma and Psychological Factors

Vestibular Schwannoma

The surgery of a vestibular schwannoma induces balance disorders which have a an impact on the patient's daily life and disrupt their quality of life. But the balance disorders don't seem to be the only ones factors that impaired the patient's quality of life. It has been alrealdy shown that emotional and psychological factors are also related to patient's quality of life. This study evaluates the relationship between the balance control compensation and these factors (i.e. emotional and psychological) in the vestibular schwannoma resection process.

Portal Hypertension and Liver Resection in Patients With Hepatocellular Carcinoma

Primary Liver Cancers

According to the BCLC guidelines, surgical resection of hepatocellular carcinoma complicating cirrhosis is restricted to patients with preserved liver function, single nodule without vascular invasion and with hepatic venous gradient below 10 mmHg. However, other guideline treatment, especially from eastern countries demonstrated that surgical resection is safe and feasible and provides better survival than the treatment recommended by the BCLC system for patients with similar stage. The primary goal of this study is to assess the impact of HVPG on short and long-term outcomes in HCC patients who undergo liver resection.

Immunological Markers Screening for Colorectal Cancer

Colorectal Cancer

Colorectal cancer incidence is increasing at an alarming rate in China. Recent reports concluded aberrant immunological function was associated with colorectal cancer outcome, however, the influence of immunocyte subgroup and immunologic factors on cancer outcome in colorectal cancer survivors is largely unknown.The investigators will explore the impact of immunocyte subgroup and immunologic factors on colorectal cancer disease-specific, disease-free and overall survival. The investigators will recruit approximately 5,000 patients as a prospective study cohort. During follow up, the investigators will explore the association of these factors with outcome of patients. The investigators believe that this project will improve the understanding of the impact of immunocyte subgroup and immunologic factors on colorectal cancer outcome.

Genome Wide SNP Array-based Approach to Detect Micro-cytogenetic Lesions and KIT Mutation to Improve...

Myeloid Leukemia

Core binding factor (CBF) positive acute myeloid leukemia (AML) consist of 15% of patients in overall AML, expected to harbor a favorable prognosis. However, around a half of cases relapses. Accordingly, more sophisticated classification in CBF positive AMLs is essential to achieve further improvement in the treatment outcome. The current study is designed to evaluate CBF positive AML patients with genome-wide SNP array and KIT mutation study in CBF positive AML patients diagnosed at the Samsung Medical Center and Hwasun Chonnam National University Hospital, Korea between 1994 and 2008. Construction of the CBF positive AML patient cohort: clinical database establishment (including treatment outcomes and prognosis) and extraction/storage of tumor cell DNAs from marrow samples, then processing of Affymetrix SNP array 6.0. Construction of prognostic predictive model using pharmacogenomics with the results of genotypes and copy number variations (CNVs). Detection of hidden microscopic cytogenetic lesions with SNP array technique, and correlation with clinical outcomes in CBF positive AML. Detection of KIT, FLT3/ITD, and NPM1 gene mutation and its correlation with clinical outcomes in CBF positive AML. The current study attempts to analyze genetic data of core binding factor (CBF) positive acute myeloid leukemia (AML) using genome wide SNP array technique with tumor DNAs collected at the time of diagnosis. To detect microcytogenetic lesions and will analyze its prognostic significance To analyze genome-wide genotypes and copy number variations (CNVs) using pharmacogenetic approach and will construct a prognostic predictive model To detect KIT, FLT3/ITD and NPM1 mutation and evaluate its prognostic significance. The present study will establish individualized therapy for CBF positive AML, will provide a basis for molecular marker guided clinical trial in CBF positive AML.

Validation of a Multi-gene Test for Lung Cancer Risk

Lung Cancer

The purpose of this study is to determine the validity of a multi-gene Lung Cancer Risk Test (LCRT). In the process, the investigators will establish a bank of NBEC samples and corresponding blood samples from individuals demographically at increased risk for lung cancer.

Establishment and Characterization of Patient-Derived Non-Small Cell Lung Cancer Xenografts and...

Non Small Cell Lung Cancer

Xenografts and cell cultures provide sufficient material for analyses at the protein, RNA and DNA level. Patient derived NSCLC xenografts and cell lines are available but none however are Asian in origin. Given the emerging evidence to suggest inter-ethnic differences in NSCLC biology, new models of preclinical drug evaluation should be designed and validated using Asian tumors. Furthermore, such models will allow studies of biological mechanisms of sensitivity and/or resistance and also the study of dynamic regulations under standardized conditions in the Asian context.

Usefulness of Interferon-gamma Release Assay in Diagnosing Pulmonary Nodules

Solitary Pulmonary Nodule

Among the causes of the solitary pulmonary nodule (SPN), benign causes including tuberculosis was noted on 15 to 60 percents in various studies. Although the characteristics of chest imaging is helpful in diagnosis and percutaneous needle biopsy for pulmonary nodule has been represented high diagnostic yield in many reports, but still surgical biopsy has been needed in definite diagnosis of pulmonary nodules in many cases. The aim of this study is to evaluate the usefulness of interferon-gamma release assay in addition to the percutaneous needle biopsy, in diagnosis of pulmonary nodules.

Response Evaluation in Malignant Pleural Mesothelioma

Malignant Pleural Mesothelioma

Recently, a few small trials have shown promising results on value of fluoro-2-deoxy-D-glucose and positron emission tomography imaging in response assessment in Malignant Pleural Mesothelioma. These studies considered different parameters in Positron Emission Tomography (PET) analysis, mainly the standardized uptake value and volume-based parameters such as total glycolytic volume.
