INTRODUCTION Positron emission tomography (PET) is a mainstay in the preoperative evaluation of various cancers. In gastric cancer however, its role in the initial staging remains contentious. Presented is a case series of three gastric patients wherein the use of fluorodeoxyglucose (18F-FDG) PET/CT (computer tomography) as part of the initial staging was inconsequential to treatment, demonstra...

BACKGROUND The validity of N classification of the 7th edition of the American Joint Committee on Cancer/Union Internationale contre le Cancer (AJCC/UICC) tumor-node-metastasis (TNM) staging system is still under debate. The purpose of this study was to evaluate the prognostic efficacy of the 7th edition of the AJCC/UICC TNM staging system (focusing on N stage), in comparison with the 6th editi...

OBJECTIVES Accurate staging of oesophageal cancer (OC) is vital. Bibliometric analysis highlights key topics and publications that have shaped understanding of a subject. The 100 most cited articles investigating radiological staging of OC are identified. METHODS The Thomas Reuters Web of Science database with search terms including "CT, PET, EUS, oesophageal and gastro-oesophageal junction c...

BACKGROUND AND OBJECTIVES Treatment of colonic cancer patients is highly dependent on the depth of tumor invasion (T-stage) as well as the extension of lymph node involvement (N-stage). We aimed to systematically review the accuracy of endoscopic ultrasound (EUS) for staging of colonic cancer proximal to the rectum. PATIENTS AND METHODS Men and women with colonic adenocarcinomas were included...

Various techniques, including standard bronchoscopy, transthoracic needle aspiration and mediastinoscopy, are used for diagnosis and staging of lung cancer. Minimizing the number of invasive procedures for lung cancer diagnosis and staging is preferred, however, and a growing number of bronchoscopic techniques are being used. Currently available techniques for the initial diagnosis of lung canc...

despite many advances in the treatment of breast cancer, it is still the second most common cause of death in women in the united states. it has been shown that inflammation plays a major role in the treatment of these cancers and inflammatory factors enhance tumor growth, invasion, metastasis, and vascularization. in this study, we would like to analyze peripheral blood neutrophil-lymphocyte r...

OBJECTIVE To classify automatically lung tumor-node-metastases (TNM) cancer stages from free-text pathology reports using symbolic rule-based classification. DESIGN By exploiting report substructure and the symbolic manipulation of systematized nomenclature of medicine-clinical terms (SNOMED CT) concepts in reports, statements in free text can be evaluated for relevance against factors relati...

The growing role of multimodal treatment plans for advanced gastric cancer has contributed to the development of more accurate preoperative staging strategies. The high diagnostic efficacy of video-laparoscopy as regards the M factor has been reported by many; preoperative laparoscopy therefore permits to avoid unhelpful surgical exploration in case of peritoneal dissemination of tumor or liver...

The tumor, lymph node, metastasis (TNM) classification system that has been in use worldwide since the 1980s was built on the premise that the anatomic extent of a majority of solid tumors is one of the most robust prognostic markers in cancer management. The TNM system is used by physicians and cancer registrars to categorize patients into important groups for treatment planning, clinical tria...

BACKGROUND Accurate staging is crucial for treatment selection and prognosis prediction in patients with rectal cancer. Point spread function (PSF) reconstruction can improve spatial resolution and signal-to-noise ratio of PET imaging. The aim of this study was to evaluate the effectiveness of 18F-FDG PET/CT with PSF reconstruction for initial staging in rectal cancer compared with conventional...
