目的探讨16-SCT对胃癌淋巴结转移的评估,给外科治疗确定淋巴结清除范围提供依据。方法统计经胃镜、病理学检查证实的141例胃癌患者的临床资料,分析其16-SCT表现,并与手术、病理学检查结果做对照分析。结果16-SCT显示早期胃癌22例,进展期胃癌119例。早、中、晚期胃癌淋巴结转移率依次呈递增趋势(P<0.05)。浸润型(BorrⅢ、Ⅳ)胃癌的淋巴结转移率(76.5%)明显高于局限型(BorrⅠ、Ⅱ)胃癌的淋巴结转移率(43.2%)。肿瘤直径<4cm、4～8cm和>8cm的淋巴结转移率依次增加,有显著性差异(P<0.01)。结论16-SCT扫描对中晚期胃癌诊断价值较大,可指导临床手术和治疗方案的制订。
Objective To investigate the evaluation of 16-SCT in lymph node metastasis of gastric cancer and provide basis for the surgical treatment of lymph node clearance. Methods The clinical data of 141 cases of gastric cancer confirmed by endoscopy and pathology were analyzed and their 16-SCT findings were analyzed. The results of the 16-SCT were compared with the results of surgery and pathology. Results 16-SCT showed 22 cases of early gastric cancer and 119 cases of advanced gastric cancer. The rate of lymph node metastasis in early, middle and advanced gastric cancer showed an increasing tendency (P <0.05). The rate of lymph node metastasis (76.5%) in infiltrating type (Borr Ⅲ) gastric carcinoma was significantly higher than that in type Ⅰ (Ⅱ) gastric cancer (43.2%). Lymph node metastasis rate of tumor with diameter <4cm, 4 ~ 8cm and> 8cm increased in turn, with significant difference (P <0.01). Conclusion 16-SCT scan is more valuable for the diagnosis of advanced gastric cancer and can guide the development of clinical surgery and treatment.
