Extraluminal cancer spreadings such as peritoneal dissemination, liver metastases, lymph node metastases and infiltration to surrounding organs were examined in 236 patients with gastric cancer by ultrasound (US). Peritoneal dissemination was found in 36 of 236 cases. Ascites, nodules in the cul-de-sac and thickned wall of the transverse colon could be detected by US in 24 of 36 cases (sensitivity of 67%). Liver metastases were detected in 18 out of 23 cases (78%). Infiltration to the surrounding organs, mainly to the pancreas, was impossible to demonstrate by US. Sensitivity was 44% (17/39).
Lymph node metastases in the region around the celiac axis were indicated in 30 of 40 cases (75%) by US. Para-aortic nodal metastases were also detected in 27 of 34 cases (79%). Ultrasonic images of para-aortic lymph node metastases were classified into four figures: i) plate type, ii) sandwich type, iii) unilateral multiple type, iv) unilateral solitary type.
These types were not necessarily the same in indication of laparotomy, selection of combined or adjuvant therapy, significance of nodal dissection and also prognosis. Solitary involved para-aortic node near the left renal vein should be removed in a case free from peritoneal dissemination or liver metastases.
Ultrasound could be very useful in screening patients with gastric cancer for peritoneal dissemination, liver metastases and lymph node metastases.
