Endoscopic ultrasonography for gastric cancer: does it influence treatment?

摘要: This study aimed to evaluate the utility and shortcomings of endoscopic ultrasound (EUS) in tumor node metastasis (TNM) staging gastric cancer its influence on treatment. The series included 126 patients (65 men 44 women) with who underwent EUS from July 1997 June 2003 at National University Hospital, Singapore. final analysis 109 ranging age 29 97 years (mean, 63.13 years). for primary disease: Specimen histology was available 102 surgery. accuracy 79% T1, 73.9% T2, 85.7% T3, 72.7% T4. overall 80.4%. nodes: sensitivity detecting nodal disease 74.2% N0, 78% N1, 53.8% N2, 50% N3. Overall, N by showed a 82.8%, specificity 74.2%, positive predictive value 85.4%, negative 70.2%, an 77.7%. Radical gastrectomy proposed 95 basis computed tomography (CT) scan, 87 (91.6%) Preoperative accurately predicted operative strategy 89% patients. No significant predictor achieved performing logistic regression correct T stage using adjusting location (middle part/distal third/whole stomach vs proximal/cardioesophageal) (p = 0.873), operator 0.546), subject’s sequence (initial 50 last cases) 0.06). Ultrasound is most accurate reliable method preoperative carcinomas, it mandatory if tailored therapeutic approach planned according stage.
