To reveal changes of peripheral markers and blood perfusion parameters in vivo tumor in the study of QL1101 and Avastin® in patients with Non-squamous Non-small Cell Lung Cancer

This Study evaluate the effect of Polymorphism in the Excision repair cross-complementing group 5 (ERCC5) (rs1047768 and rs751402) gene on the clinical outcome of Platinum-based regimens used in the treatment of Non-Small Cell Lung Cancer (NSCLC) patients

Erlotinib is an inhibitor of the epidermal growth factor receptor (EGFR) tyrosine kinase. Higher response rates were observed in a subset of patients with female gender, Asian ethnicity, no smoking history, mutations in EGFR tyrosine kinase, high EGFR gene copy number and adenocarcinoma histology. However, the therapeutic effect of Erlotinib is not confined to patients whose tumors harbor EGFR mutations and other predictors of efficacy of this agent. And these tests require time and sufficiently large specimens for processing, whereas many patients with advanced NSCLC are diagnosed based on cytology alone. This study was designed to evaluate FLT-PET or FDG-PET usefulness in the early assessment of treatment response and in predicting patient outcome after erlotinib monotherapy for patients with non-small cell lung cancer prospectively. Changes in tumor FLT or FDG uptake 7 days after the initiation of treatment will be compared between responders and nonresponders based on subsequent CT scans.

To establish a retrospective compilation of clinical, histopathological, treatment and follow-up (clinic pathological) data of previous non-small cell lung cancer (NSCLC) cases. To establish a prospective collection of clinic pathological information from NSCLC patients with corresponding blood and tissue samples To discover and validate molecular biomarkers of survival and treatment outcome in NSCLC One of the current difficulties in the management of lung cancer is the decision to treat and the type of treatment to select. Thus there is a need for additional prognostic (indicative of disease aggressiveness) and predictive (indicative of likely response to treatment) markers for lung cancer. To conduct a successful prognostic and predictive marker program, several factors are required, including: a comprehensive database linking clinical, histopathological, treatment and outcome characteristics of each case, a collection of samples linked to the database that is suitable for the testing of candidate markers, and a multi-disciplinary, interdepartmental level of expertise in the management of lung cancer. Objective 1: A review of the case records will be conducted to extract clinical, treatment and follow-up data Objective 2: Patients aged 21 years or more with newly diagnosed, untreated non-small cell lung cancer shall be approached for consent. Patients will be identified through the pathology records, and from the study investigators' clinic. After subject consent, baseline characteristics will be obtained. Follow up data on therapies received and toxicities encountered will be obtained. Tumor samples will be obtained only from patients with NSCLC undergoing surgery as part of routine clinical care. The surgical specimen will be sent to Pathology to verify the adequacy of the diagnostic sample as per usual practice. Blood will be collected at the baseline (or prior to any anti-cancer treatment) and will be sampled again at the time of relapse or disease progression. Collection will entail drawing 7ml blood into a Vacutainer CPT tube (Becton Dickinson, USA), centrifugation, extraction of a separated layer of mononuclear cells (MNC), labeling followed by storage below -80oC. The frequency of blood drawn will be about 1-5 times (7-35mls total). The number of times depends on whether the lung cancer relapses and in the advanced stage, how often the lung cancer relapses after treatment. DNA and RNA will be extracted by CSIS and stored in freezer space there. Stored samples will be used for investigation of prognostic and predictive markers of outcome and for discovery of novel molecular alterations Objective 3: Biomarker analysis of tumor and blood. Blood will be enriched for circulating tumor cells (CTC) using previously optimized methods (11) and DNA will be extracted from CTC and tumor using the Tri-Reagent (Molecular Research Center, Cincinatti, OH). DNA will be extracted from tumor, CTC and mononucleated cells and tested for somatic lung mutations by sequencing (2). Germline DNA will be analysed for genes linked to genetic risk for NSCLC and, for treatment toxicities, for genes related to NSCLC chemotherapy metabolic pathways. Tissue microarray (TMA) is a high-throughput method of analysing large numbers of formalin-fixed, paraffin-embedded tumor at a minimal cost and effort. To analyse the expression of proteins of putative relevance to EGFR function, cell proliferation, angiogenesis, apoptosis, metastasis, and hormonal, TMA will be utilised. PTEN and C/EBPa will also be analysed.

The purpose of our study is to investigate the association between respiratory muscle performance, functional capacity, dyspnea, anxiety/depression symptom, 1-year respiratory morbidity rate, and 1-year mortality in patients with primary stage IIIb and IV lung cancer.

Non-small cell lung cancer (NSCLC) has a poor prognosis if not caught early enough. One of the factors that may impact the ability to control NSCLC is low oxygen levels (hypoxia) inside the tumour. This study will use 18F-FAZA PET scans to assess whether patients have hypoxic tumours and to monitor the changes to the hypoxic areas of a tumour during currently available standard treatment. It is hypothesized that 18F-FAZA PET may predict response to treatment, local control, and/or survival in NSCLC.

The aim of this study is to evaluate if Electromagnetic navigation (ENB) in combination with rapid on site evaluation (ROSE) can improve diagnostic accuracy in those patients who fail to be diagnosed with conventional fluoroscopic assisted bronchoscopy (FBS) in combination with ROSE.

Promising new technology exists to examine small proteins that are shed by cancers into the blood stream. The purpose of this study is to see if there are differences in the proteins and protein levels in blood from individuals with early stage lung cancer compared to healthy adults.

Lung cancer is the main cause of mortality by cancer in France. The lung cancer stage at time of diagnosis is a major determinant of survival. To date, 75% of lung cancer are diagnosed at an advanced stage with worse survival). Lung cancer screening is based on low dose CT scan which allows to decrease lung cancer related mortality of 20% in patients aged 55-74 years-old with a history of tobacco consumption ≥ 30 PY active of who quite < 15 years. These criteria for eligibility for lung cancer screening lead to 1 to 2% of lung cancer diagnosis at the first CT scan. In our experience regarding 1 year of lung cancer surgical resection, only 45% of the patients presented criteria for lung cancer screening. Moreover, the duration of tobacco consumption would provide a better stratification of lung cancer risk compared to only PY. Therefore, other criteria for lung cancer screening eligibility could be proposed. Currently, 9 out of 10 lung cancer is linked with tobacco consumption which is also a major risk factor for atherosclerosis-associated cardiovascular events. Around 40% of patients with a lung cancer have a history of atherosclerosis-associated cardiovascular event, mainly coronary artery diseases and peripheral artery diseases. Main Objective: The objective is to compare the observed rate of lung cancer prevalence in our study to the rate of around 2 % observed in lung cancer screening trials in south Europe (France and Italy). The investigators hypothesize that the population of patients with a history of atherosclerotic cardiovascular event associated with tobacco consumption present a higher prevalence of lung cancer compared with the population of patients eligible for lung cancer screening program which is defined by age and history of tobacco consumption.

The investigators will prospectively recruit 100 NSCLC patients. The cfDNA samples will be gathered before the surgery and postoperatively 4-6 weeks after surgery and at 6 and 12 months follow-up visits. This study aims to investigate the role of ctDNA in NSCLC patients treated with curative intent surgery. Preoperative ctDNA will be compared to primary tumor DNA to investigate the concordance of mutations and gained mutations from possible primary tumor cancer stem cell. Preoperative ctDNA findings will be tested for associations with baseline characteristics as well as clinically important factors such as TNM stage, histopathological findings, and tumor volume. The investigators aim to identify molecular residual disease (MRD) using multiple ctDNA samples after the surgery and search the associations with clinical recurrence and survival, with possible correlation to palliative chemotherapy response Using multiple ctDNA samples, the investigators will gather information about tumor heterogeneity, diversity of disease genotypes, and dynamic changes in ctDNA. If additional data from palliative immunotherapy (PD-L1 inhibitors) is available, the effect of this will be evaluated in the study.
