目的探讨胃癌卵巢转移患者的临床病理特点及误诊原因。方法对1990年1月至2004年6月发生的52例胃癌卵巢转移患者的临床资料、病理结果及误诊原因进行回顾性分析。结果胃癌卵巢转移患者平均年龄(40.15±1.28)(22￣64)岁,常以卵巢转移灶为首发表现。B超检查以混合性包块或实质性包块为主要表现,多伴有腹腔积液,双侧卵巢转移瘤占76.9%。血清C A125升高,平均(99.85±14.23)U/m L,但显著低于同期原发性卵巢癌(P<0.05)。术前诊断准确率低(46.1%)。结论胃癌卵巢转移与原发性恶性肿瘤无可靠的鉴别诊断标准,卵巢转移瘤超声、C T等影像检查技术无特异性,术前诊断需行多方面的综合分析。 Objective To investigate the clinicopathological features and misdiagnosis of patients with gastric cancer with ovarian metastasis. Methods The clinical data, pathological findings and the causes of misdiagnosis in 52 cases of gastric cancer with ovarian metastasis from January 1990 to June 2004 were analyzed retrospectively. Results The average age of patients with gastric cancer metastasis (40.15 ± 1.28) (22 ~ 64) years old, often with ovarian metastasis as the first performance. B-ultrasound to mixed mass or substantive mass as the main performance, and more associated with ascites, bilateral ovarian metastases accounted for 76.9%. Serum C A125 increased (mean, 99.85 ± 14.23) U / m L, but significantly lower than that of primary ovarian cancer (P <0.05). The accuracy of preoperative diagnosis was low (46.1%). Conclusion There is no reliable diagnostic criteria for ovarian metastasis of gastric cancer and primary malignant tumor. The imaging techniques such as ultrasound and C T of ovarian metastatic tumor are nonspecific. The preoperative diagnosis should be comprehensively analyzed in many aspects.
