Abstract:
An accurate preoperative evaluation of lymph nodes(LNs) in gastric cancer is a prerequisite for successful surgery and favorable prognosis. We retrospectively analyzed the Ct accuracy in perigastric LN localization and LN staging of gastric cancer as well as the size criteria for the metastasized LN in 64 patients who hed undergone a surgery for gastric cancer. The results of perigastric LNs evaluation by CT are as follows; sensitivity 67%(64/95), specificity 90%(839/929), accuracy 88%(903/1024). Of 95 pathologically metastasized LN groups, 66 could be retrospectively identified on Ct scans(69%). In LN staging, CT was correct in 60%(38/64), overstaged in 32%(21/64), and understaged in 8%(5/64). The perigastric LN groups which were easily localized on CT were #3, 7, 8, and 13. The mean size of metastasized LNs on CT according to the I.N group was #3 (13mm), #4(9mm), #6 (10mm), #7(10.5mm), #8 (10mm), #9 (11mm), #13 (9mm).
