BACKGROUND Postoperative radiotherapy (PORT) for thymic tumor is still controversial. The object of the study is to evaluate the role of PORT for stage I to III thymic tumors. METHODS The Chinese Alliance for Research in Thymomas (ChART) was searched for patients with stage I to III thymic tumors who underwent surgical resection without neoajuvant therapy(More)
BACKGROUND To compare surgical outcomes of thoracoscopic and laparoscopic esophagectomy with open esophagectomy in order to study the learning curve of minimally invasive surgery for esophageal cancers. METHODS Among 109 esophageal cancer patients retrospectively studied, 59 patients underwent minimally invasive esophagectomy (MIE) and 50 underwent open(More)
BACKGROUND It is so far not clear that how myasthenia gravis (MG) affected the prognosis of thymoma patients. The aim of this assay is to compare the postoperative survival between patients with thymoma only and those with both thymoma and MG. METHODS The Chinese Alliance for Research in Thymomas (ChART) registry recruited patients with thymoma from 18(More)
Short-range continuous-wave Doppler radar sensors have been mainly used for noncontact detection of various motions. In this paper, we investigate the feasibility to implement the function of a remote mouse, an input device of a computer, by recognizing human gestures based on a dual-channel Doppler radar sensor. Direct conversion architecture, symmetric(More)
In this study, we investigate the group delay distortion of a signal due to the presence of dispersion in transmission systems, and propose an approach to eliminate the distortion by dispersion compensation based on engineered material dispersion. We demonstrate that utilizing the anomalous frequency response of a dispersive material, envelope distortion of(More)
BACKGROUND The 7th edition Union for International Cancer Control esophageal cancer staging system has changed the pathological N stage from N0, N1 (the existence state of regional lymph node metastasis) to N0, N1, N2, and N3 (number of regional lymph node metastasis). This study was designed to analyze the influencing factors of early recurrence in(More)
BACKGROUND To evaluate the surgical outcomes of tumor resection with or without total thymectomy for thymic epithelial tumors (TETs) using the Chinese Alliance for Research in Thymomas (ChART) retrospective database. METHODS Patients without preoperative therapy, who underwent surgery for early-stage (Masaoka-Koga stage I and II) tumors, were enrolled for(More)
OBJECTIVES Surgeons at different institutions worldwide choose different types of operations for thymic tumours. It is not known whether these differences affect the outcomes of the patients. METHODS A total of 1430 patients with Masaoka-Koga pathological Stage I-II thymic tumours without myasthenia gravis or pre-treatment were identified from the(More)
BACKGROUND The aim of this study is to investigate the value of pretreatment biopsy for histological diagnosis and induction therapies in the management of locally advanced thymic malignancies. METHODS The clinical pathological data of patients with thymic tumors in the Chinese Alliance for Research in Thymomas (ChART) who underwent biopsy before(More)
BACKGROUND To compare the predictive effect of the Masaoka-Koga staging system and the International Association for the Study of Lung Cancer (IASLC)/the International Thymic Malignancies Interest Group (ITMIG) proposal for the new TNM staging on prognosis of thymic malignancies using the Chinese Alliance for Research in Thymomas (ChART) retrospective(More)
