Active clinical trials for "Lung Neoplasms"

The purpose of this study is to evaluate the use of Dynamic PET/CT as a tool to assess disease response to anti-cancer therapy in Lung Cancer patients.

The present study has been designed in order to characterize the incidence of patients with advanced non-small cell lung cancer (NSCLC) carrying epidermal growth factor receptor (EGFR) positive mutations and their clinical management in Galicia.

a. VEGFRs may be the biomarker which can predict the effect of bevacizumab in non small cell lung cancer

The presence of genetic alterations in the tyrosine kinase domain of the oncogene (eg. EGFR and ALK) is associated with the clinical response to tyrosine kinase inhibitors (TKIs) in patients with non-small cell lung cancers. Therefore, the detection of altered genetic alterations is useful for predicting the treatment response for TKIs in non-small cell lung cancer patients. However, good quality tumor tissues are available only in <50% of patients with inoperable lung cancer for mutation analysis. In this study, the investigators will detect and quantify the genetic alterations in plasma. the investigators will investigate if the serial measurement of cancer-derived genetic alterations in plasma can provide a means for monitoring disease progression, as well as treatment response. In addition the investigators will analysis the resistant mechanism of TKIs and chemotherapy with plasma tumor DNA.

Several arguments are in favor of a therapeutic monitoring for the erlotinib, therefore, a pharmacokinetic (PK) has been prepared using data from the literature. This model must be validated at concentrations achieved in practice. This is a preliminary study before the implementation of a randomized trial confirming the therapeutic monitoring of erlotinib through this model.

Lung cancer is the most common cause of cancer death in Canada. For approximately 30% of patients that present with locally-advanced non-small cell lung cancer (NSCLC), the standard treatment is curative-intent concurrent chemoradiotherapy. Outcomes remain poor, with 5-year survival of only 20%. Despite the long-held belief that higher radiation doses lead to improved overall survival (OS), the landmark randomized trial (RTOG 0617) showed the opposite. The investigators hypothesize that the inferior survival observed may be due to unexpected heart toxicity as secondary analysis revealed that the heart dose was a strong predictor of inferior OS. Up to now, change in heart function is typically detected histologically, requiring autopsy tissue. Therefore, a non-invasive marker of early heart damage is required. Hybrid PET-MRI has become available in Canada only recently. The ability to simultaneously perform metabolic imaging with functional and tissue imaging allows for novel assessment of heart toxicity. The primary objective is to examine the utility of hybrid PET-MRI and DCE-CT to assess acute changes in heart function and to measure inflammation before, and six weeks after NSCLC radiotherapy. A pilot of 20 patients with Stage I-III NSCLC will be enrolled. The findings of this study will aid in the design of new studies to reassess dose escalation for locally advanced NSCLC while limiting the risk of heart toxicity. FDG PET will be used to simultaneously assess both cardiac inflammation and tumour response. Quantitative DCE-CT will also be used to measure ventilation and perfusion changes in the normal lung and tumour after radiotherapy, providing image data that can comprehensively assess both tumour response and potential toxicity in both the heart and lungs. Such information is crucial in understanding the disease and its response to treatment. This data will also aid in the design of radiation techniques that spare the heart in other patients with any thoracic malignancies, including breast cancer, lymphoma, and esophageal cancer.

The investigators conduct the real world study to explore the efficacy and safety of Albumin-binding taxol in lung cancer .

This study evaluate the association of body composition (mainly free-fat mass), clinical and biochemical parameters with development of toxicity in patients under treatment with Carboplatin/Paclitaxel in advanced NSCLC.

Study on the tumor immune escape in advanced non-small cell lung cancer patients with EGFR and ALK mutant negative by NGS combined with RNAseq

Purpose of the study: To observe the efficacy and safety of Anlotinib Hydrochloric Therapy in Patients with advanced Lung cancer in real world. Subjects of the study: advanced Lung cancer. Methods of the study: This is a real world, prospective, Non-Interventional, Follow-up registration study. Patients will get Anlotinib according to their condition and willingness. Anlotinib will give orally, once daily on days 1-14 of a 21-day cycle. After the procedure, regular follow up after every cycle. End point: Primary end point: progression-free survival (PFS). Secondary end points: overall survival (OS), disease control rate (DCR), overall response rate (ORR).
