Gastric stump cancer is often described as a tumor with a poor prognosis and low resectability rates.
To compare the pathological characteristics of gastric stump cancer patients with those of patients with proximal gastric cancer.
This retrospective study was based on the demographic and pathological data of patients diagnosed with gastric cancer and treated at Assaf Harofeh Medical Center during an 11 year period. The patients were divided into two groups: those undergoing proximal gastrectomy for proximal gastric cancer and those undergoing total gastrectomy for gastric stump cancer.
Patients with gastric stump cancer were predominantly male, older (P = 0.202, not significant), and had a lower T stage with less signet-ring type histology, fewer harvested and fewer involved lymph nodes (P = 0.03, statistically significant) and less vascular/lymphatic involvement than patients with proximal gastric cancer.
The lower incidence of involved lymph nodes and lymphovascular invasion in gastric stump cancer as compared to proximal gastric cancer in this study may imply that the prognosis of gastric stump cancer may be better than that of proximal gastric cancer. However, to verify this assumption a study comparing patient survival is required.
残胃癌常被描述为一种预后较差且切除率较低的肿瘤。
比较残胃癌患者与近端胃癌患者的病理特征。
这项回顾性研究基于11年间在阿萨夫·哈罗费医疗中心被诊断为胃癌并接受治疗的患者的人口统计学和病理数据。患者被分为两组：因近端胃癌接受近端胃切除术的患者和因残胃癌接受全胃切除术的患者。
与近端胃癌患者相比，残胃癌患者以男性为主，年龄较大（P = 0.202，无统计学意义），T分期较低，印戒细胞型组织学较少，获取的淋巴结和受累淋巴结较少（P = 0.03，有统计学意义），血管/淋巴管受累较少。
本研究中，与近端胃癌相比，残胃癌的淋巴结受累和淋巴血管侵犯发生率较低，这可能意味着残胃癌的预后可能优于近端胃癌。然而，要验证这一假设，需要进行一项比较患者生存率的研究。
