Filter by:The purpose of this project is to validate a new combined MRI and PET imaging technique as a biomarker or measure of glycolysis in brain tumors. To accomplish this, the investigators propose obtaining image-guided measures of tissue pH and biopsied tissue in tumor areas selected for bulk resection surgery. Investigators will then correlate the imaging measurements with pH, RNA expression, protein expression, and bioenergetics measurements of key glycolytic enzymes.
Leptomeningeal metastasis (LM) is a complication of advanced non-small cell lung cancer (NSCLC). The incidence of LM in NSCLC patients is around 3-5 %, reaching 9.4 % of those with an epidermal growth factor receptor (EGFR) mutation. Generally, the efficacy of systemic treatment for LM is limited due to the blood-brain barrier. Osimertinib has a high central nervous system penetration rate, making it the preferred first-line treatment for EGFR-mutant NSCLC. Previous studies indicated that osimertinib had shown promising efficacy in pretreated patients harboring EGFR mutations and LM. However, intracranial disease progression eventually develops, and the prognosis of patients with LM progression after osimertinib is poor. Recently, intrathecal chemotherapy with pemetrexed (IP) was reported to be an alternative treatment in patients with NSCLC and LM. The results from a phase I/II trial examining the efficacy and safety of IP in patients with EGFR-mutant NSCLC after the failure of previous TKI, and 83% of study enrollees received osimertinib before IP. The clinical response rate was 84.6%, and the median overall survival was 9.0 months. Despite initial promising efficacy, further trials are needed to verify these results. Therefore, the investigators plan to conduct a prospective study to examine the safety and effectiveness of IP combined with EGFR-TKI for patients with EGFR mutant NSCLC after osimertinib failure.
Patients with recurrent or metastatic uterine cervical squamous carcinoma have very poor prognosis. For eligible patients, radiotherapy remains the choice, which has the most effective impact on the survival periods. On the hand, anti-angiogenic therapy has been proved to be promising treatment for recurrent or advanced cervical carcinomas. This study aims to discover the objective response of combination therapy with nimotuzumab (an anti-epidermal growth factor receptor [EGFR] IgG1 humanized monoclonal antibody) and radiotherapy in recurrent or metastatic uterine cervical squamous carcinoma in a single-arm, open, phase 2 clinical trial. The primary endpoint is the objective response rate evaluated by imaging methods. The second endpoints are the progression-free survival and overall survival. The treatment toxicity is regarded as one the second endpoint.
The aim of this study is to investigate the efficacy and safety of intercalated combination of erlotinib and radiotherapy for patients with EGFR-mutant, unresectable, locally advanced NSCLC, and to explore a new treatment strategy for this subset. After Induction by erlotinib, local radiotherapy is intercalated, and followed by 24-week erlotinib maintenance.
Patient with Non-Small Cell Lung Cancer (NSCLC) that might have a genetic change (mutation) in the Epidermal Growth Factor Receptor (EGFR) are invited to take part in this study. This research study is evaluating a new blood test that is capable of detecting an EGFR mutation in cancer without a biopsy.
