P1.05-025 PROGNOSTIC SIGNIFICANCE OF HEPATITIS B VIRUS TO<br />

Background: Hepatitis B virus (HBV) is considered to be a major cause of<br />

hepatocellular carcinoma. However, little is known about the role of chronic<br />

HBV infection in other malignancies. We aimed to determine HBV infection<br />

with other well established prognostic factors and performed multivariate<br />

survival analyses to evaluate its value in Chinese non-small cell lung cancer<br />

(NSCLC) patients. Methods: It is a retrospective evaluation of the impact of<br />

HBV infection status in 366 patients who underwent complete surgical<br />

resection for stage IB NSCLC NSCLC patients in Shanghai Chest Hospital from<br />

1998 to 2008. All the patients were Shanghai Niece and all the stage IB NSCLC<br />

patients didn’t receive adjuvant chemotherapy. The patients’ blood samples<br />

were tested with chemiluminescent immunoassay for the presence of HBV<br />

surface antigen (HBsAg), antibodies against HBV core antigen (anti-HBc), and<br />

antibodies against HBsAg (anti-HBs) before operation. Other variables in the<br />

analysis included age, gender, history of smoking and pathologic type. HBsAg<br />

positive was definite as HBV infection. Results:<br />

for searching potential biomarkers in lung cancer patient. Methods: EBC<br />

sample collected using specific device called R-tube, containing both the<br />

volatile organic compounds (VOCs) and non-volatile organic compounds<br />

(NVOCs), were obtained from patients with lung cancer (n = 20) and control<br />

healthy individuals (n = 5). The EBC samples were applied to high resolution<br />

metabolomics (HRM) based LC-MS for comparison of metabolic differences<br />

among healthy people and lung cancer patients in order to detect potential<br />

biomarkers. The multivariate statistical analysis was performed, including a<br />

false discovery rate (FDR) of q=0.05, to determine the significant metabolites<br />

between the groups. 2-way hierarchical clustering analysis (HCA) was done<br />

for determining the classification of significant features between the control<br />

healthy and lung cancer patients. The significant features were annotated<br />

using Metlin database (metlin.scripps.edu/) and the identified features were<br />

then mapped on the human metabolic pathway of the Kyoto Encyclopedia<br />

of Genes and Genomes (KEGG). This study was approved by Korea University<br />

Guro Hosipital Institutional review board (KUGH14273) Results: Using<br />

metablomics-wide associated study (MWAS), metabolic changes among<br />

healthy group and lung cancer patients were determined. The 2-way HCA<br />

identified the different metabolic profile in lung cancer patients from healthy<br />

control. The identified potential biomarkers are Acetophenone (m/z 103.0542,<br />

[M+H-H 2<br />

O] + ), P-tolualdehyde (m/z 138.0914, [M+NH4] + ), 2,4,6-Trichlorophenol<br />

(m/z 218.9134, [M+Na] + ) and 11(R)-HETE (m/z 343.2233, [M+Na] + ). The<br />

top 5 of affected KEGG pathways are Arachidonic acid metabolism,<br />

Glycerophospholipid metabolism, Bile secretion, Inflammatory mediator<br />

regulation of TRP channels and Tyrosine metabolism. Conclusion: Our result<br />

shows that Acetophenone, P-tolualdehyde, 2,4,6-Trichlorophenol and 11(R)-<br />

HETE are significantly higher in lung cancer patients. Acetophenone and<br />

2,4,6-Trichlorophenol are classified as a Group D human carcinogen approved<br />

by US Environmental Protection Agency (EPA), while 11(R)-HETE is associated<br />

with Arachidonic acid metabolism and P-tolualdehyde is related to xylene<br />

degradation pathway and degradation of aromatic compounds pathway. Our<br />

identified metabolites can be the potential biomarkers in EBC for the early<br />

and non-invasive detection of lung cancer.<br />

51 HBV infection cases (13.93%) were positive in stage IB NSCLC. The 5-year<br />

overall survival of patients without or with chronic HBV infection were 71.25%<br />

and 50.98% (P=0.028). Multivariate analyses revealed that gender, chronic<br />

HBV infection were significant predictive factors for overall survival (P< 0.05).<br />

Conclusion: The chronic HBV infection is a significant independent prognostic<br />

factor in stage IB non-small cell lung cancer.<br />

Background: Early and non-invasive detection of lung cancer is a desirable<br />

prognostic tool for prevention of lung cancer at early stages. Previously,<br />

unusual human breath smell of lung cancer patients detected by trained<br />

dogs played an important role in early detection of lung cancer. Which<br />

suggests that exhaled breath condensate (EBC) is a promising source<br />

Background: A multi-institutional squamous lung cancer consortium of<br />

investigators is developing prognostic signatures through the US NCI Lung<br />

SPECS (Strategic Partnership for Evaluation of Cancer Signatures) program.<br />

Six institutions contributed tumor specimens and published/unpublished<br />

expression-based prognostic signatures for validation using standardized<br />

sample cohorts (a primary validation cohort comprising institutional cases,<br />

and additional validation cohorts from two prospective cooperative group<br />

studies) and quality controlled assessment in independent laboratory and<br />

statistical cores. Here, we report on de novo prognostic signatures derived<br />

using the pooled institutional dataset. Methods: Highly quality-controlled<br />

cases of primary SCC from the pooled cohort (N=249) were analyzed to<br />

generate de novo prognostic signatures from among the 147 genes comprising<br />

pre-existing signatures, and from among all profiled genes. Minimax Concave<br />

Penalty (MCP) selection and Ward’s minimum variance clustering yielded<br />

survival analyses with 2 clusters that were evaluated using Cox regression and<br />

bootstrap cross validation (bCV; 500 iterations). Results: Two significantly<br />
