Abstract
Introduction: Gastric tumor is relatively common disease entity in day to day radiologicpratice.Gastric cancer acounts for the majority of gastric neoplasm followed by GIST andgastric lymphoma. Imaging plays a vital role in diagnosis and staging of gastric neoplasmparticularly gastric cancer.Computed tomography remains the most common and widespreadtool for the staging of the diseasesThe role of computed tomography in the study of gastric carcinoma is mainly for preoperativelocal and distant staging; post-therapeutic control and follow-up
Method: The study was conducted at TASH ,Addis Ababa ,Ethiopia from September 2019 toAugust 2020.Hospital based retrospective cross sectional study was conducted to address thespecific objective during study period. The Study was conducted among patients being evaluatedat Tikur Anbessa Specialized Hospital oncology department who have both MDCT result reported by senior radiologist and pathology result . Data was collected by evaluating the MDCT report and biopsy result from pathology and oncology department by using structuredquestionnaires. The data was checked for clarity and completeness. Computerized data analysiswas conducted by using SPSS version 20 software.
Result: Total of 80 gastric tumor patients were evaluated .66(82.5%) were gastric cancer12(15.5%) were gastric GIST and 2(2.5%) were primary gastric lymphoma. The age range ofgastric cancer were 25 to 85 years with mean age of 52.6 year.The mean age of GIST was 54year and the age range of the 2 lymphoma were 35 to 54 years.56.7 % of gastric cancer weremen and 66 % of GIST were men. This study showed that 56 % of gastric cancer wereintestinal histologic type, 33. 4 % were diffuse histologic type and 10.6% were indeterminate histologic adenocarcinoma .Acuracy of MDCT for staging T4 tumor is 90.9% and 44.5 % forT3 .
Conclusion: MDCT has relatively high diagnostic sensitivity and specificity for detection anddiagnosis of gastric tumor .It has high acuracy to differentiate gastric GIST from other gastrictumor . MDCT has high acuracy for correctely staging T4 tumor but it had relatively low acuracy of staging T2, T3 tumor and nodal staging
