Abstract

INTRODUCTION

Gastric cancer accounts for nearly half a million deaths each year all over the world. Dynamic abdominal CT is used for preoperative diagnosis and staging of gastric cancers. Preoperative staging must be done correctly, so the patient can get the proper treatment options such as neoadjuvan chemotherapy. To further clarify of preoperative role of dynamic abdominal CT; we compared preoperative CT findings with postoperative, and histopathological findings.

METHODS

Patients’ records, who underwent gastric operation for gastric cancer, between 2016 to 2019 were analyzed retrospectively. All preoperative CT findings were compared with surgical and histopathological findings statistically, and also preoperative CT images were evaluated by another radiologist postoperatively.

RESULTS

For 3 year period total 103 patients were diagnosed and operated for gastric cancer in our clinic. The population was comprised of 76 (73.7%) male and 25(24.2%) female patients who were averagely 67 years old. All of the patşents have preoperative dynamic abdominal CT. Preoperative CT findings for staging and also diagnosis were insufficient for 16 (15.84 %) patients of 101. The treatment options, mortality and morbidity rates for 16 patients did not change, because additional imaging technics (PET CT, MRI, EUS) and endoscopy were performed to these patients preoperatively.

DISCUSSION AND CONCLUSION

Dynamic abdominal CT has a major role for preoperative diagnosis and staging of gastric tumors, but some cases could be misevaluated, so that preoperative evaluation of gastric tumors should be done with dynamic CT and if necessary MRI, PET CT, EUS or endoscopy.
