Abstract :

Introduction: Accurate staging of carcinomas of stomach is helpful in improving the prognosis. USG is initial modality of choice when investigating non–specific complaints where in doubtful cases or if USG suggests a resectable stomach malignancy, computed tomography (CT) often provides additional information. Objectives: To evaluate the diagnostic accuracy of USG and computed tomography (CT) for staging of carcinoma stomach. Methodology: 50 patients were selected for the study for which they underwent USG and computed tomography (CT) examination after explaining the entire procedure and the risks involved. Results: In Our study, stomach cancer was most common in 6th decade followed by 5th decade, with stomach cancers were more common in males compared to females with ratio of 1.17:1.0. Patients presented with weight loss (80%) as most common symptom followed by early satiety (70%) and poor appetite (68%). Most of gastric cancer arises from distal stomach (72) followed by proximal stomach (20%) and diffuse involvement of stomach in 8%. The most common histo–pathological type is adenocarcinoma (90%). CT is more sensitive in detecting stomach cancer (96%) while Trans–abdominal USG has lower sensitivity of 46%. Accuracy rates for each T stage with MDCT is 50% for T1, 71.3% for T2, 72.7% for T3 and 100% for T4 while with trans–abdominal US is 50% for T1, 66.67% for T2, 81.81% for T3 and 71.42% for T4. Sensitivity, specificity and accuracy of CT in detecting nodal metastasis (N–stage) was 86.11 %, 78.57 % and 84 % respectively and sensitivity, specificity and accuracy of trans–abdominal US in detecting nodal metastasis (N–stage) was 75 %, 64.28 % and 72 % respectively. Most common metastatic feature was peritoneal nodules (44%) followed by liver (18%), lung (12%) and ovarian metastasis (12%). Conclusion: USG being less expensive and radiation free, is the first line investigation in patients of stomach cancers but CT remains the investigation of choice as it is superior diagnostic imaging modality than USG prior to treatment which improved detection and characterization of tumor contribute to better diagnostic accuracy and consequently reduction of invasive procedure which lead to significant reduction of mortality and morbidity from tumor.
