The effect of preoperative treatments on lymph node counts after total gastrectomy in esophagogastric adenocarcinoma.

For esophagogastric adenocarcinoma, PCRT reduced total LNs count after total gastrectomy with D2 lymphadenectomy, whereas PCT did not. In the PCRT group, LNs count was lower in both radiation target and peritarget areas than in the SF group but only in radiation target area than in the PCT group. The correlation between TRGs and total LNs count remained unclear.
