Filter by:The purpose of this study is to evaluate the addition of cisplatin to first-line chemotherapy with gemcitabine in elderly patients with non small cell lung cancer in terms of overall survival.
Activating somatic mutations of the tyrosine kinase domain of epidermal growth factor receptor (EGFR) have been characterized in a subset of patients with advanced NSCLC.The EGFR mutation rate was 30% in Chinese Non-small Cell Lung Cancer(NSCLC). Patients harboring these mutations in their tumors show excellent response to EGFR tyrosine kinase inhibitors (EGFR-TKIs). This randomized phase III trial is studying gefitinib to see how well it works compared to cisplatin-based chemotherapy in treating patients who have undergone surgery for stage II-IIIA(N1-N2) NSCLC with EGFR activating mutation in Asian population.
The purpose of this study is to determine if the images of the primary lesions of lung cancer and any metastatic lesions seen from the investigational SPECT/CT 99mTC-EC-DG scans are the same as the PET/CT 18F-FDG scans.
This clinical trial studies image-guided hypofractionated radiation therapy (RT) when given together with hypofractionated RT boost and combination chemotherapy in treating patients with stage II-III non-small cell lung cancer (NSCLC) that cannot be removed by surgery. RT uses high energy x-rays to kill tumor cells. Hypofractionated RT may be able to send x-rays directly to the tumor and cause less damage to normal tissue. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving RT together with combination chemotherapy may kill more tumor cells and allow doctors to save the part of the body where the cancer started
Cisplatin and pemetrexed combination or carboplatin, paclitaxel and bevacizumab are now considered as standard treatment in non-squamous cell lung carcinoma (NSCLC). Both main registrative trials are considered positive because they reached their objectives, but within them, the Quality of Life (QoL) of patients was not detailed neither has represented as primary objective of the studies. It is considered that, together with enhancements that are added to the knowledge of the biology of NSCLC, QoL may influence the therapeutic choice if one of the associations show to be better tolerated by the patient and favours an amelioration of his QoL.
Apatinib is a new kind of Vascular endothelial growth factor receptor(VEGFR) tyrosine kinase inhibitors (TKIs). The investigators have finished the preclinical and phase I and phase II clinical study for apatinib and found its satisfactory anti-tumor activity and tolerated toxicities. A disease-control rate of 75% was found in lung cancer patients. In the present phase III trial, the investigators will further evaluate the efficacy and toxicities of apatinib in the treatment of advanced non-squamous non-small cell lung cancer.
Lung cancer is the leading cause of cancer deaths in Taiwan. The carcinogen in the environment is a key role in the development of lung cancer, and one of its main resource is tobacco. Activated carcinogens in the organism lead to mutations of crucial oncogenes resulting in tumor development. Genes such as Cytochrome P-450 family, GST (glutathione S-transferase) family, UGT (UDP-Glucuronosyltransferase) family, ERCC-1(excision repair cross-complementing rodent repair deficiency),ERCC-4 and ERCC-5,are encoding antioxidant enzymes or involving in the DNA repair process and the production of some transcription factors. In recent years, many studies have shown the correlation between these genes and the susceptibility of lung cancer. Each gene has a different role in the tumor development pathway. CYP, UGT, GST, NAT2 (N-acetyltransferase 2) and NQO1(NAD(P)H:quinono oxidoreductase 1) involve in the production of antioxidant enzymes. The antioxidant enzymes can detoxificate hydrogen peroxide or defense against oxidative stress. However, the genetic polymorphisms may influence the function of detoxification, which cause the increase in the susceptibility of lung cancer. P53 and MDM2 genes play important roles in the production of tumor-suppression proteins and the regulation of transcription factors, which may regulate the growth and the apoptosis of cell cycle and influence the susceptibility of lug cancer. The polymorphisms in ERCC genes may cause the damage in the DNA repair process which might also cause increase in lung cancer susceptibility. The overexpression of epidermal growth factor receptor is highly correlated with increasing risk of the non-small cell lung cancers. The overexpression may induce the proliferation of cancer cells and the inhibition of the apatosis. Therefore, in recent years, EGFR has been widely studied as the new target of the drugs and the susceptibility of the lung cancer. In addition,the genetic polymorphisms in drug metabolism channel proteins, like OCT2 (organic cation transporter), ATP7A, ATP7B and ABC (ATP-binding cassette) transporter may have influence on the metabolism, the efficacy and the toxicity of the drugs.
The aim of the study is to assess current practice within PROP & lung teams, for treating asymptomatic patients with centrally located non-small cell lung cancer (NSCLC), and to observe outcomes for those patients receiving immediate or deferred RT. This is a prospective cohort trial. Patients will be managed by immediate radiotherapy (RT) or a deferred approach according to physicians' individual current clinical practice. Baseline and follow-up data collection will be structured to focus on patient-reported measures to describe clinical outcomes in the two management groups. Indications for prescribing RT and dose fractionation schedules will also be collected. A new intervention will not be introduced during this trial. Instead, a follow-up regimen will be offered to both groups of patients, so that RT can be offered to the deferred group of patients if/when symptoms develop, and we can monitor symptoms/toxicities and QoL in both groups of patients.
This an an open-label study to define the safety profile and the maximum tolerated dose and confirm the clinical effective dose of palifosfamide-tris given intravenously in combination with etoposide and carboplatin in a wide range of cancers which etoposide and carboplatin are normally given. Once the maximum dose of palifosfamide-tris is determined,a Phase II study using the 3 agents combined will begin.
Lung cancer and esophageal cancer remain the leading causes of cancer death worldwide. The main problem is lack of effective tool in early detection that accounts for the poor outcome of cancer. Clinically, over 80% of patients with cancer were at late stage when they were diagnosed. Therefore, it is important for us to find the biomarker that serve as the early prediction of cancer. The investigators have published that VEGFC over-expressed in non-small cell lung cancer. VEGFC plays a critical role in regulating motility of tumor cells, promotes proliferation of lymphatic endothelial cells and enhances migration and invasion. Investigator found that VEGFC over-expressed in the serum of esophageal cancer patients. Therefore, it is worthwhile to investigate the correlation between VEGFC, clinical lung cancer and esophageal cancer. MicroRNAs (miRNAs) are conserved, endogenous, small, and noncoding RNA molecules of 21~23 nucleotides that function as post-transcriptional gene regulators. Recent studies indicated that certain microRNAs reduced in cancer patients. Therefore it is important to investigate whether specific microRNA changed in certain kinds of cancer patients.
