From 1941 through 1983, a total of 66 patients with sacrococcygeal teratoma were seen, representing 41 percent of the total of 162 patients with teratomas from all anatomic sites seen over this period. Forty-six (70 percent) of the patients with sacrococcygeal teratomas were female and 34 (52 percent) were neonates. Younger patients had a significantly better prognosis. Approximately half (48 percent) of the patients had benign tumors. Of the other 34 patients, 19 (29 percent) had frank malignancy, being either a purely malignant tumor or a tumor with malignant mixed with benign elements, and 15 (23 percent) patients had tumors containing embryonic but no malignant components. Patients with tumors containing mature adult or embryonic tissues have a good prognosis. However, malignant sacrococcygeal teratoma portends a bleak prognosis irrespective of therapy (in this series only one patient survived among 19 patients with an average survival of 16 months after diagnosis).
从1941年到1983年，共诊治了66例骶尾部畸胎瘤患者，占同期所见来自所有解剖部位的162例畸胎瘤患者总数的41%。骶尾部畸胎瘤患者中46例（70%）为女性，34例（52%）为新生儿。年龄较小的患者预后明显较好。约一半（48%）的患者患有良性肿瘤。在其他34例患者中，19例（29%）为明确的恶性肿瘤，即单纯恶性肿瘤或恶性与良性成分混合的肿瘤，15例（23%）患者的肿瘤含有胚胎组织但无恶性成分。含有成熟成人或胚胎组织的肿瘤患者预后良好。然而，恶性骶尾部畸胎瘤无论接受何种治疗，预后都很黯淡（在本系列中，19例患者中只有1例存活，诊断后平均存活16个月）。
