Background: Staging of non-small cell lung cancer (NSCLC) is important for determining choice of treatment and prognosis. The accuracy of FDG-PET scans for staging of lymph nodes is too low to replace invasive nodal staging. It is unknown whether the accuracy of integrated FDG-PET/CT scanning makes invasive staging redundant. Methods: In a prospective study, the mediastinal and/or hilar lymph n...

For many years, small cell lung cancer (SCLC) has been staged using the Veterans Affairs classification system, which includes only 2 stages: limited (primary tumor and regional lymph nodes within a tolerable radiation field) and extensive (anything beyond limited stage). The TNM staging system used for non-small cell lung cancer is also prognostic for SCLC and should be integrated into the cla...

Staging provides essential prognostic information relevant for choosing adequate therapy and should also identify patients with resectable distant metastases. Preoperative staging consists of clinical examination, blood counts, liver and renal function tests, carcino-embryonic antigen (CEA), chest X-ray or CT scan, CT scan of the abdomen, and colonoscopy of the entire large bowel, i.e. with pos...

Small cell lung cancer (SCLC) has been primarily classified as limited or extensive, with limited stage confined to the primary tumor and regional lymph nodes. In the future, the TNM staging system should be integrated into the classification of SCLC. The appropriate staging work-up for patients with SCLC has traditionally included contrast-enhanced computed tomography (CT) scans of the chest a...

AIMS PET-CT scans are routinely performed in patients with lung cancer after investigation by chest x-ray (CXR) and CT scan, when these have demonstrated potentially curable disease. If the majority of patients with lung cancer potentially suitable for curative treatment could be identified earlier in the diagnostic pathway on the basis of CXR findings they could be referred for PET-CT imaging ...

introduction: squamous cell carcinoma (scc) is the most common head and neck malignancy. to decrease the side effects of treatment and mortality from disease relapse, careful staging for the proper treatment plan is necessary. the main purpose of this prospective study is to compare the diagnostic value of computed tomography (ct) and magnetic resonance im-aging (mri) in oral scc and its lymph ...

INTRODUCTION Esophageal cancer staging has been performed through bronchoscopy, computerized tomography (CT), positron emission tomography (PET), and endoscopic ultrasound (EUS). Whereas CT and PET scan provide assessments of distant metastasis, bronchoscopy importantly diagnoses tracheobronchial involvement, complementing chest CT findings. EUS is the most accurate examination for T and N stag...

Routine staging includes physical examination, chest X-ray, head and neck endoscopy, and head and neck CT scan or MRI. A thoracic CT scan may be carried out to rule out metastatic disease. Squamous cell head and neck cancer should be staged according to the TNM system and grouped into the following categories (Table). T4 tumors are subdivided into T4a resectable and T4b unresectable. Stage IV i...

positron emission tomography (FDG-PET)/CT scan for staging demonstrated hypermetabolic FDG uptake in the lung mass (figure 1A) and an unexpectedly focal FDG uptake in the left paraspinal muscle (figure 1B). Physical examination was normal. Biopsy from the muscle showed infiltration with cells of adenocarcinoma. A revision of the initial CT scan revealed a mass in the left paraspinal muscle whic...
