Objective:
To investigate the related factors of recurrence of early gastric cancer (EGC) after endoscopic resection.
Methods:
Clinicopathologic data of 169 patients with EGC who underwent endoscopic resection and periodically followed up by the Chinese PLA General hospital were analyzed retrospectively.
Results:
During a follow-up of 13 - 57 months (median time 24.5 months), 12 patients had gastric cancer again and the recurrence rate was 7.1% (12/169). The recurrence time varied from 3 to 36 (28 ± 23) months and the median time was 18 months. The recurrence rates of 0.5 year, 1(st) year, 2(nd) year and 3(rd) year were 1.18% (2/169), 3.55% (6/169), 9.91% (11/111) and 12.24% (12/98), respectively. Eleven patients had gastric cancer again within 2 years after resection. Undifferentiated histology (including poorly differentiated carcinoma and signet ring cell carcinoma), submucosal infiltration and lymphovascular invasion of the primary lesion of EGC were related to the postsurgical recurrence (all P < 0.05).
Conclusion:
Most recurrence of EGC occurred within 2 years after endoscopic resection and is related with undifferentiated histology, submucosal infiltration and lymphovascular invasion. It is important for these patients to receive endoscopy follow up.
