Filter by:Epidermal growth factor receptor (EGFR) tyrosine kinase is one of most popular target molecules in the field of anticancer drug research. EGFR is highly expressed in many types of tumor cells, which could activate EGFR cytosolic kinase activity by binding to its ligand EGF, and regulates gene expression, cell proliferation, differentiation, apoptosis through different signal transduction pathways. Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), competitive to specifically combined with the EGFR kinase domain, thus inhibits its kinase activity, thereby blocking cancer cell proliferation or metastasis. At present, EGFR-TKI has been widely used in clinical activity, especially in patients with EGFR mutations, which had been proved to achieved a certain effect. But with the passage of time, a drug resistance is inevitable. At present, studies have found that the cessation of treatment immediately after EGFR-TKI resistance may lead to rapid progress of cancer. Chemotherapy, as one of the most widely accepted modality in cancer treatment, might also be one of the salvage therapies of target treatment. Therefore, in patients with better physical status (PS) scores, chemotherapy is commonly applicable. In January 2010, a study published in the journal of Clinical Lung Cancer reported the application of chemotherapy as salvage treatment for advanced non-small cell lung cancer (NSCLC) patients with resistant to first-line EGFR-TKI treatment. Of the 114 patients enrolled, 67 received sequential chemotherapy, the other 47 patients received best supportive care. The results showed that, sequential chemotherapy can improve the survival time of the patients, compared with chemotherapy and supportive care groups (11.2 months vs. 3.8 months, P< 0.01). Furthermore, in those who received sequential chemotherapy, a regimen containing paclitaxel got higher efficiency and disease control rate than those without (48.7% vs. 21.4%, 79.5% vs. 53.5% , P< 0.05), as well as longer progression-free survival (PFS, 5.1 months vs. 1.8 months, P< 0.01) and overall survival (OS, 12.7 months vs. 7 months, P< 0.01). Another study in Taiwan which enrolled 195 patients treated with at least 1 cycles sequential chemotherapy after first-line gefitinib shown similar results. Generally, gefitinib as a first-line treatment had PFS for 5 months, and the second-line treatment efficiency was 14.4%. Regimens of platinum or paclitaxel had a better treatment efficiency (50.6%). A poor therapeutic effect was reported for gefitinib as second-line therapy (5.6%). In total, the median OS of second-line treatment was 12.2 months. In addition, platinum containing regimens survival better (21.7 months vs. 8.9 months, P< 0.01); patients with mutant EGFR benefit more in a platinum-based chemotherapy (24.5 months vs. 8.5 months, P< 0.05). Bevacizumab (trade name Avastin ®) is a kind of recombinant humanized monoclonal immunoglobulin gamma-1 (IgG1) antibody, which can selectively inhibit the combination process of vascular endothelial growth factor (VEGF) and its receptor, Flt-1 and kinase domain receptor (KDR) in endothelial cells. A reduction of tumor angiogenesis, blood supply, oxygen and other nutrients supply could be obtained after the VEGF loss of its biological activity, thus inhibit tumor growth. The drug was approved for the first-line treatment of advanced colorectal cancer in 2004 by America food and Drug Administration (FDA),thus became the first for clinical use of drugs that targeting VEGF. As the first globally approved anti-angiogenic monoclonal antibody drugs, bevacizumab has approved for advanced colorectal cancer, lung cancer, breast cancer, renal cell carcinoma and malignant glioma patients, which was used in more than 500000 cases. In the field of advanced NSCLC treatment, clinical results confirm bevacizumab combined with chemotherapy can prolong OS and PFS of patients with NSCLC, and well tolerated. The thirty-fifth annual meeting of the European Society of Medical Oncology (ESMO) conference released a meta analysis results of bevacizumab combined with platinum chemotherapy for first-line treatment of advanced non squamous NSCLC. It is confirmed that, treatment with bevacizumab based chemotherapy for advanced non squamous NSCLC patients could achieve significant survival benefit, prolong remission time, and expected safety. Therefore, the investigators design this phase II to testify the efficacy and safety of bevacizumab + chemotherapy for EGFR-TKI resistant non squamous NSCLC.
This randomized phase II trial studies the safety and effects of acetylsalicylic acid (aspirin) taken continuously or intermittently on gene expression in the nasal tissue of current smokers. Smokers are at increased risk of developing lung cancer. Acetylsalicylic acid may be useful in preventing lung cancer.
EGFR-tyrosine kinase inhibitor(TKI)- ie, erlotinib, gefitinib, has been recommended as the first option for EGFR-mutated IIIb/IV NSCLC by serial trials as it prolonged patients' progression-free survival. The OPTIMAl trial indicated that those who received TKI and chemotherapy during the whole treatment window survived longest. Unfortunately, previous studies(INTACT, TRIBUTE et al) that concurrently combined TKI and cytotoxic regimens failed to improve survival in unselected patients. To avoid the potential synergistic antagonism, the FAST-ACT II trial committed a sequential strategy and find a superiority in the combination arm upon chemotherapy even in EGFR-mutated group. However, pharmaceutically, the continuous administration of an EGFR-TKI before subsequent chemotherapy in FAST-ACT II could obviate the effects of cytotoxic agents due to the erlotinib-induced G1 arrest. On the basis of these and other studies, the investigators hypothesized that a better sequential combination strategy of EGFR-TKI and chemotherapy (adding a EGFR-TKI wash-out window before chemotherapy) would be more efficacious than chemotherapy alone. In this study, the investigators investigate the efficacy(PFS:progression free survival), safety, and adverse-event profile of chemotherapy plus intermittent and maintenance of erlotinib, when these drugs were used as first-line treatment in who had non-squamous lung carcinoma with EGFR gene mutation in China.
This pilot clinical trial studies single photon emission computed tomography (SPECT)/computed tomography (CT) in measuring lung function in patients with cancer undergoing radiation therapy. Diagnostic procedures that measure lung function may help doctors find healthy lung tissue and allow them to plan better treatment.
This randomized pilot clinical trial studies body warming in improving blood flow and oxygen delivery to tumors in patients with cancer. Heating tumor cells to several degrees above normal body temperature may kill tumor cells.
This clinical trial studies whether screening methods used to diagnose cancer of the prostate, lung, colon, rectum, or ovaries can reduce deaths from these cancers. Screening tests may help doctors find cancer cells early and plan better treatment for lung cancer.
This phase I trial studies the side effects and the best dose of veliparib when given together with paclitaxel and carboplatin in treating patients with solid tumors that are metastatic or cannot be removed by surgery and liver or kidney dysfunction. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving veliparib together with paclitaxel and carboplatin may kill more tumor cells.
This study collects information on the side effects of proton therapy and detailed information on the proton therapy treatment plan itself. This may help researchers develop methods to predict the risk of side effects for future patients and learn the long-term benefit of proton therapy.
This research studies collecting and storing tissue and blood samples from patients with lung cancer who are undergoing surgery. Collecting and storing samples of tissue and blood from patients with lung cancer to study in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.
This clinical trial studies yoga-based rehabilitation in reducing physical and emotional side effects of living with cancer or its treatment. Yoga-based rehabilitation may reduce side effects and improve the quality of life of patients with breast, lung, or colorectal cancer.
