ARTICLE HIGHLIGHTS
Research background
Borrmann type IV (B-4) gastric cancer (GC) accounts for about 10% of all GC cases in Asia. Some B-4 patients were found to have no distant metastasis by preoperative detection and underwent curative surgery, which was defined as circumscribed B-4 in our study.
Research motivation
Research of clinicopathological characteristics and prognosis in B-4 is rare, especially for the circumscribed B-4 patients.
Research objectives
In this study, we aimed to identify the factors related to prognosis and postoperative peritoneal cavity metastasis (PPCM) for circumscribed B-4 patients and to further explore the appropriate therapeutic strategies.
Research methods
A total of 117 circumscribed B-4 patients were included in this study. Survival analysis and Pearson correlation analyses were performed to identify the factors related to prognosis.
Research results
Subtotal gastrectomy combined with chemotherapy could significantly improve the long-term survival time for circumscribed B-4. Positive lymph node staus was the only factor correlated with PPCM, and chemotherapy was useful for suppressing PPCM in patients with subtotal gastrectomy but not in those with total gastrectomy.
Research conclusions
Lymph node status is an independent prognostic factor for circumscribed B-4 patients. Subtotal gastrectomy and chemotherapy could effectively improve prognosis and suppress PPCM.
Research perspectives
This study recommended reasonable treatment schedules for circumscribed B-4 patients, but a multi-center study on a larger scale is necessary in the future.
