[Application of jejunal interposition after radical proximal gastrectomy].

Objective: To explore an ideal method of digestive tract reconstruction and tolerance to adjuvant chemotherapy after radical proximal gastrectomy.

Methods: Thirty patients in the reconstruction group were treated by jejunal interposition, and other 30 patients received gastroesophagostomy (control group). The operation time, operation risk, occurrence of reflux esophagitis and postoperative 1-, 3-, 6-month nutrition statuses were evaluated.

Metastatic pattern of lymph node and surgery for gastric stump cancer.

Background And Objectives: Metastatic pattern of lymph node (LN) and surgery options for gastric stump cancer (GSC) remain controversial. The aim of this study was to investigate LN metastasis and lymphadenectomy for GSC for curative purposes.

Methods: Sixty-seven patients with GSC were analyzed retrospectively.

[Significance of COX-2, p53, proliferating cell nuclear antigen and nm23 expressions in gastric cancer and its behavior].

Background & Objective: Molecular biological studies indicated that abnormal expression of cyclooxygenase-2(COX-2), p53, proliferating cell nuclear antigen(PCNA), and nm23 correlate with the development of gastric cancer, but the relationship between abnormal expression of above gene proteins and the biological behavior of gastric cancer was not yet clear. This study was designed to investigate the relationship between expressions of COX-2, p53, PCNA, and nm23 and the clinicopathological behavior in gastric cancer.

Methods: The expressions of COX-2, p53, PCNA, and nm23 were detected by using immunohistochemical(SP) method.
