D2 Gastrectomy (d2 + gastrectomy)
Selected AbstractsD2 gastrectomy , a safe operation in experienced hands,INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 6 2005R.S. Date Summary In the contemporary practice, surgery is the only potentially curative treatment available for gastric cancer. However, there is no consensus on the extent of surgical resection. Advantages of D2 gastrectomy in terms of morbidity, mortality, local recurrence and survival are confirmed in Japanese as well as some European trials. In our hospital, all patients with operable gastric cancer are treated with D2 gastrectomy along with splenectomy and distal pancreatectomy followed by jejunal pouch reconstruction. The study was undertaken to evaluate our practice in terms of postoperative morbidity and mortality. All the patients who had total gastrectomy for gastric carcinoma from January 1995 to December 2000 were included in the study. During this 6-year period, 33 patients underwent potentially curative D2 gastrectomy. Postoperative morbidity and mortality were 18 and 9%, respectively. There were no anastomotic leaks. Three (9%) patients developed dysphasia, of which two (6%) had anastomotic stricture requiring dilatation. We feel D2 gastrectomy with splenectomy and distal pancreatectomy when performed electively is a safe procedure in experienced hands. Oesophago-jejunal anastomosis can be safely performed using circular stapler.

The expression of Cdx2 and nuclear PTEN was studied using immunohistochemistry of paraffin-embedded tumor specimens from 99 patients who underwent radical D2 gastrectomy between 1999 and 2001. Cdx2 and nuclear PTEN expression were detected in 39.6% (36 of 91) and 70.3% (64 of 91) of gastric cancer cases, respectively. There was a negative correlation between Cdx2 expression and Lauren classification (p=0.032), and between nuclear PTEN expression and lymph node metastasis (p=0.049). Patients with Cdx2-positive, or nuclear PTEN-positive expression had higher survival rates than those with Cdx2-negative or nuclear PTEN-negative expression (p<0.001 and p=0.003, respectively). Co-expression of Cdx2 and nuclear PTEN showed significantly lower levels in diffuse- or mixed-type cancers than in intestinal-type cancers (p=0.005). Multivariate analysis revealed that Cdx2 expression was an independent prognostic indicator of gastric cancer (p=0.014). These data suggest that combined analysis of Cdx2 and nuclear PTEN expression can have significant value in distinguishing histological types of gastric cancer and assessing prognosis in patients with gastric cancer.
