The prognosis of gastric remnant cancer is considered to be poor compared with that of primary cancer.
This study was conducted to elucidate the differences of clinicopathologic findings and treatment results between 59 patients with gastric remnant cancer (GRC) and 579 patients with primary proximal gastric cancer (PGC).
There was no significant difference in the incidence of lymph node metastasis between GRC and PGC. However, changes in the metastatic pattern to lymph nodes were observed in GRC. In GRC, the tumor easily invaded the neighboring organs due to the adhesions around the remnant stomach, resulting in a low resectability with curative intent. The 5-year survival rate after curative resection for advanced GRC was 50.9%. GRC patients without serosal invasion had a good prognosis.
Although the survival rate after curative resection for GRC patients was similar to that of PGC, GRC patients without serosal invasion had a better prognosis. Therefore, early detection is an important way to improve overall survival in GRC.
与原发性胃癌相比，残胃癌的预后被认为较差。
本研究旨在阐明59例残胃癌（GRC）患者与579例原发性近端胃癌（PGC）患者在临床病理特征和治疗结果上的差异。
GRC与PGC的淋巴结转移发生率无显著差异。然而，在GRC中观察到淋巴结转移模式的变化。在GRC中，由于残胃周围的粘连，肿瘤容易侵犯邻近器官，导致根治性切除的可切除性较低。进展期GRC根治性切除后的5年生存率为50.9%。无浆膜侵犯的GRC患者预后良好。
尽管GRC患者根治性切除后的生存率与PGC相似，但无浆膜侵犯的GRC患者预后较好。因此，早期检测是提高GRC总体生存率的重要途径。
