AIM: The aim of this study was to evaluate the reliability of thin-slice hydro-multidetector row computed tomography (MDCT) in assessing resectability and lymph node staging of gastric cancer.
METHODS: Sixty-one patients (37 males, 24 females; mean age 61 years) with gastric cancer, and whose surgery was planned, underwent preoperative abdominopelvic hydro-MDCT at slice thickness of 5 mm. We evaluated the tumor stage, depth of tumor invasion into the gastric wall, metastasis of lymph node, and presence/absence of distant metastases on the CT images produced with multiplanar reconstruction (MPR) and hydro-CT technique. The results were compared with pathological and surgical findings. Diagnostic accuracy was also analyzed.
RESULTS: Of 61 patients with gastric cancer, 6 (14%) were inoperable, 45 (68%) were advanced stage, and 10 (16%) were early stage gastric cancer patients. The detection rate of the primary tumor was 97% for MDCT; the overall accuracy of MDCT in the determination of the depth of invasion and serosal involvement when compared with pathological staging were 84% and 95%, respectively; the overall accuracy rate in lymph node staging was 73.5%.
CONCLUSION: MDCT can improve the accuracy of preoperative T and N staging of gastric cancer and will contribute to treatment strategies for patients with advanced stage gastric cancer.
