BACKGROUND: Metastatic adenocarcinoma to the uterine cervix from gastric cancer is rare, and the clinicopathologic features of this metastasis are unclear. METHODS: A clinicopathologic review of 16 patients with metastatic adenocarcinoma to the uterine cervix from gastric cancer was performed. RESULTS: The ages of the patients ranged from 29 to 57 years, and 81.3% of the patients were premenopausal. Nine of the patients had undergone gastrectomy previously. In 11 patients the histologic type of the gastric cancer was poorly differentiated adenocarcinoma and, in 5 patients, signet ring cell carcinoma. The cervical metastasis was diagnosed 11-121 months (mean, 57.5 months) after the diagnosis of the gastric cancer in 10 of the patients. In six patients, the cervical metastasis was discovered synchronously or before the diagnosis of the gastric cancer. The colposcopic findings were normal in 57.1%, but 56.3% had abnormal cervical smears. In all patients, tumor cells were present in the dilated lymphatics of the cervix. Metastases to the uterine body and bilateral ovaries were common, and half of the patients had metastases to the paraaortic lymph nodes. Extirpation of the cervix was performed in six patients. The prognosis was poor, regardless of the treatment method. CONCLUSIONS: The route of metastasis to the cervix is surmised to be retrograde lymphatic, and this extension is often slow. Periodic gynecologic examinations should be performed indefinitely for premenopausal female patients with advanced gastric cancer.
