Nodal staging

چکیده
Lymph node metastases are a poor prognostic indicator in many tumours and therefore accurate identification during staging is important prior to commencing treatment. The presence of lymph node metastases can significantly alter patient management and therefore accurate diagnosis of the presence and extent of nodal disease can help optimise patient management. In this review, the radiologic features that aid in the differentiation of malignant and benign lymph nodes are discussed. The keys to successful interpretation on cross-sectional computed tomography (CT) and magnetic resonance imaging of nodal metastases are highlighted. The clinical role of positron emission tomography-CT imaging for nodal staging is discussed and emerging imaging techniques that may further improve nodal staging accuracy are surveyed.

Lymph Node Ratio for Nodal Staging in Colorectal Cancer - a Promising, but Premature Tool
10-14 regional lymph nodes, nodal staging in stage III colorectal cancer, which is solely based on the number of metastatic lymph nodes, would be inaccurate in certain circumstances. Recently, the metastatic lymph-node ratio has been suggested as an alternative tool for nodal staging in stage III colorectal cancer [2-4]. Also, after preoperative chemoradiation therapy in rectal cancer patients,...
متن کاملComparison between 18F-Fluorodeoxyglucose Positron Emission Tomography and Sentinel Lymph Node Biopsy for Regional Lymph Nodal Staging in Patients with Melanoma: A Review of the Literature
Aim. to compare (18)F-Fluorodeoxyglucose positron emission tomography (FDG-PET) to sentinel lymph node biopsy (SLNB) for regional lymph nodal staging in patients with melanoma. Methods. We performed a literature review discussing original articles which compared FDG-PET to SLNB for regional lymph nodal staging in patients with melanoma. Results and Conclusions. There is consensus in the literat...
متن کاملStaging lung cancer: role of endobronchial ultrasound
Accurate staging is the first step in the management of lung cancer. Nodal staging is quite important for physicians to be able to judge the primary operability of patients harboring no distant metastasis. For many years, mediastinoscopy has been considered a "gold standard" modality for nodal staging. Mediastinoscopy is known to be a highly sensitive procedure for mediastinal staging and has b...
متن کاملcTNM vs. pTNM: the effect of not applying ultrasonography in the identification of cervical nodal disease
Accurate clinical staging of oral squamous cell cancer can be quite difficult to achieve especially if nodal involvement is identified. Radiologically-assisted clinical staging is more accurate and informs the clinician of loco-regional and distant metastasis.In this study, we compared clinical TNM (cTNM) staging (not including ultrasonography) to pathological TNM (pTNM) staging in 245 patients...
متن کاملValidation of EBUS-TBNA-integrated nodal staging in potentially node-positive non-small cell lung cancer
OBJECTIVE Nodal staging of lung cancer is important for selecting surgical candidates. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was evaluated as a modality for nodal staging of patients with potentially node-positive non-small cell lung cancer (NSCLC). METHODS Endobronchial ultrasound-guided transbronchial needle aspiration was used for nodal staging of NSC...
متن کاملEmergency surgery for colorectal cancer does not result in nodal understaging compared with elective surgery.
BACKGROUND It has been suggested that inadequate lymph node harvest may result in pathologically understaged or indeterminate staging of patients with colorectal cancer (CRC). We compared the adequacy of nodal staging in patients undergoing emergency surgery compared with elective surgery for CRC. METHODS Using a prospectively collected CRC surgery database at a tertiary care centre, we perfo...
