Objective To detect the micrometastasis status and necessity of dissection of lymph nodes of hepatodudenal ligament in advanced gastric antral cancer. Methods Eighty-six lymph node samples of hepatodudenal ligament which were negative in routine pathological examinations were collected from 45 gastric antral cancer patients with radical dissection.The expressions of CK20 mRNA were detected for the existence of micrometastasis by RT-PCR. Results Micrometastasis was found in 46 out of 86 lymph nodes(53.49%) and 23 out of 45 patients(51.11%),significantly different from the routine pathological examinations(both P
