We present 250 cases of thymomas with emphasis on their clinical staging and follow-up. The patients were 120 males and 130 females between the ages of 13 and 92 years. Surgical resection was performed and histopathologic material evaluated in every case. Grossly, the tumors resected varied in size from 3 to 20 cm in greatest diameter. According to our proposed staging system, 31 cases were sta...

Accurate staging of cancer is of fundamental importance to treatment selection and planning. Current staging paradigms focus, first, on a detailed delineation of the primary tumour in order to determine its suitability for resection, and, thereafter, on assessment of the presence of metastatic spread that would alter the surgical approach, or mandate non-surgical therapies. This approach has, a...

Introduction: Rectal cancer staging provides critical information concerning the extent of the disease. The information gained from staging is used to determine prognosis, to guide management, and to assess response to therapy. Accurate staging is essential for directing the multidisciplinary approach to therapy. This study focuses on the evaluation of MRI in preoperative staging of rectal canc...

PURPOSE Surgical resection as part of a multimodality approach in malignant pleural mesothelioma (MPM) has a high morbidity and mortality. Because mediastinal lymph node (MLN) metastases are a negative prognostic factor, preoperative staging is of paramount importance. Transesophageal endoscopic ultrasound with real-time guided fine needle aspiration (EUS-FNA) enables accurate MLN staging in lu...

Many staging systems of hepatocellular carcinoma (HCC) were established; however, there is no consensus on which is proper in predicting prognosis. This study aims to evaluate various commonly used staging systems of HCC. Patients who underwent surgery during 2001-2007 were included. All patient data were retrospectively staged using six staging systems, that are American Joint Committee on Can...

OBJECTIVE To evaluate the feasibility of integrating robot-assisted technology in the performance of laparoscopic staging of gynecologic malignancies. METHODS Seven patients underwent robot-assisted laparoscopic staging procedures for gynecologic cancers. Data were collected and analyzed as a retrospective case series analysis. RESULTS We attempted 7 robot-assisted laparoscopic staging proc...

Rectal cancer is associated with a high risk of metastases and local recurrence; recurrence rates after surgical treatment being up to 32%. An accurate staging at the time initial diagnosis therefore very important. Magnetic Resonance Imaging (MRI) already established as an tool for preoperative rectal has resulted in marked improvements accuracy.
 Material Methods: This study used MRI com...

BACKGROUND Many liver staging systems that include the tumor stage and the extent of liver function have been developed. However, prognosis assessment for hepatocellular carcinoma (HCC) remains controversial. In this study, the performances of 7 staging systems were compared in a cohort of patients with HCC who underwent non-surgical treatment. METHODS A total of 196 consecutive patients with...

PURPOSE This study is to evaluate the Hangzhou criteria (HC) for patients with HCC undergoing surgical resection and to identify whether this staging system is superior to other staging systems in predicting the survival of resectable HCC. METHOD 774 HCC patients underwent surgical resection between 2007 and 2009 in West China Hospital were enrolled retrospectively. Predictors of survival wer...
