Significance of Gastric Wall Thickening Detected in Abdominal CT Scan to Predict Gastric Malignancy

Abstract

Background Early diagnosis of gastric cancer is one of the most important parameters affecting the survival of the disease. In this study, we aimed to stress the importance of antrum wall thickness in CT examination. Method The study included 111 patients between ages of 18 and 95 who had antral wall thickening in computed tomography and also had endoscopic evaluation performed in the same clinic. The patients were divided into two groups as benign and malignant according to the pathology results. The thickness of the antrum wall in computed tomography, hemoglobin and albumin levels, and age was compared among these two groups. Parameters with significant differences were further analyzed by multivariate analysis using logistic regression analysis. Results Of the 111 patients included in the study, 57 were male and 54 were female. Mean age was 65 years. Fifty-one patients were classified as benign and 60 patients as malignant. Mean age of the malignant patients was 70, while that of benign patients was 59 (p < 0.05). Antrum wall thickness was 13.68 ± 3.27 mm in malignant patients and 9.22 ± 2.17 mm in benign patients (p < 0.05). Similarly, hemoglobin level was significantly different in malignant and benign patients (10.78 ± 1.57 g/dl and 12.64 ± 1.43 g/dl, respectively; p < 0.05). Albumin levels were 3.36 ± 0.57 mg/dl in malignant patients and 3.97 ± 0.57 mg/dl in benign patients (p < 0.05). Conclusion Evaluation of antrum wall thickness, age, hemoglobin, and albumin values together may contribute to distinguishing the benign and malignant pathologies involving this region in patients with suspected stomach wall thickening in abdominal CT scan.

Value of multiphase contrast-enhanced CT with three-dimensional reconstruction in detecting depth of infiltration, lymph node metastasis, and extramural vascular invasion of gastric cancer

“…It is believed that GC enhancement peaks most often in the portal venous phase (17,18). In our current study, comprehensive assessment of the differentiation degree of GC by multiphase CECT improved the accuracy of GC diagnosis; similarly, the CT enhancement differences among GC with 3 different differentiation degrees were the largest in the portal venous phase, and the observation was easiest at the time of peak enhancement.…”

The Use of Clinical Parameters as Adjuncts to Endoscopic Evaluation of Mural Thickening on Conventional Computed Tomography in Diagnosing Malignancy

“…Certainly, MT in isolation poses a dilemma given the fact that some malignancies have been identified in asymptomatic patients [30]. It is this very cohort that poses the biggest clinical challenge.…”

The value of inflammatory markers in diagnosing acute appendicitis in pregnant patients

“…There are reports showing that elevated CAR levels were associated with aggressive tumor behavior and poor prognosis in oncology patients. [33][34][35] Qin et al [10] and Gibson et al [12] reported that high CAR values reflected the severity of infection in the acute phase of inflammatory bowel disease. Both studies showed that elevated CAR values were associated with the extent and severity of the infection.…”
