Filter by:In 2007 and 2013, the American College of Chest Physicians (ACCP) guidelines applied the diagnostic criteria of sMPLC （synchronous multiple primary lung cancers）, and the diagnostic criteria of Martini and Melamed were extended and developed, Summarized as: (1) different histological types, different genetic characteristics, or different origin of carcinoma in situ; (2) the histological type is the same, the tumor is located in different lung or different lung lobes, the common lymphatic drainage site of lung cancer is not cancerous, and there is no extrapulmonary metastasis at the time of diagnosis. Postoperative staging of each tumor was carried out in sMPLC patients, if all of them were stage I lung adenocarcinoma, whether adjuvant therapy could fully refer to the treatment principle of stage I NSCLC was considered, whether the benefit of subsequent application of adjuvant chemotherapy was still unclear, and whether adjuvant therapy was needed or not has been determined. High-throughput sequencing, also known as "Next generation" sequencing (NGS), is characterized by sequencing of hundreds of thousands to millions of DNA molecules in parallel, and generally shorter reads.For multiple tumor lesions resected by sMPLC, only biopsy gene information from a single cancer focus may not be enough to identify all active driver gene mutations from the tumor. Therefore, NGS sequencing was proposed for all cancer lesions of sMPLC patients to reflect the full picture of gene mutation in such patients. The investigators initiated this prospective clinical study to detect lung cancer related genes in tumor tissues and patients with at least 2 tumors that were confirmed as invasive adenocarcinoma by pathology after sMPLC resection (residual non-resectable or non-qualitative pulmonary nodules). At the same time, application of NGS technology to test lung cancer related genes in patients' tumor tissues and blood, patients with lung cancer drive genes were followed up to explore whether different drive genes had an impact on patients' disease progression. In order to investigate the type of gene that causes disease recurrence in patients, tissue or blood test was performed again when disease recurrence occur.
Epilepsy is a major disease of the nervous system (WHO, 2015), as well as the second most common neural disease. It has been recorded that there have been 65 million epilepsy patients all over the world, more than 10 million in China, resulted in high morbidity, high mortality, heavy social and social psychological burden. Due to complex etiology, which genetic playing a large part for 70%-80%, easy to recurrent, as well as various seizure types, a great heterogeneity in clinical manifestation, epilepsy is difficult to treat in general, at least 33% patients. At present, It's still a big challenge in early warning, choice of treatment, efficacy and severe adverse reaction rate, prognosis assessment. Lack of precise diagnosis based genetic and molecular bio-markers for treatment are the main key points. Recently, clinical phenotype classifications of epilepsy have been refined, the exist researches had made a progress in gene mutation mechanism and targeted therapy, which pushed epilepsy being another disease could be precise treated after tumor. It's sure to provide a breakthrough for another neural diseases if epilepsy precise treatment project are successful.
Johns Hopkins clinical research office quality assurance group will monitor and audit this study at Johns Hopkins. The Sub Investigator at each site will be responsible for internal monitoring at their site.
