title: [Study on metastasis and micrometastasis in No.14v lymph nodes of patients with lower third gastric cancer].
abstract: OBJECTIVE
  To study the metastasis and micrometastasis in No.14v lymph nodes in patients with lower third gastric cancer.
  
  
  METHODS
  A retrospective study was performed. A total of 53 patients undergoing radical resections by a single surgeon for lower third gastric cancer in the Department of General Surgery at the Affiliated Hospital of Qingdao Medical College were included. Conventional pathological section was used to detect lymph nodes metastasis and telomere TRAP-ELISA was used to identify the micrometastasis in No.14v lymph nodes.
  
  
  RESULTS
  A total of 96 lymph nodes were dissected from the No.14v group and lymph nodes metastasis were discovered in 9 patients by conventional pathological section. Forty-four patients had no metastasis on conventional pathological examination, of whom 13(29.6%) were found to have micrometastasis. The overall metastatic rate was 41.5%(22/53). Metastasis and micrometastasis in the No.14v lymph nodes were associated with Borrmann types, depth of invasion, No.6 lymph nodes metastasis, tumor diameter, and TNM staging(P<0.05).
  
  
  CONCLUSIONS
  No.14v lymph nodes in patients with lower third gastric cancer is associated with a high incidence of metastasis and micrometastasis. The status of No.6 lymph nodes may be used as an useful indicator for No.14v lymph nodes metastases during the operation.
