松果体区和它的异位肿瘤是一种罕见的脑部肿瘤,以往报告例数均较少,本文作者报告了25例病例,22例接受了Co~(60)或10MeV直线加速器的放射治疗,12例死亡,根据其中11例尸检所见,结合1960年以来文献报告的100多例材料复习,提出了治疗的改进意见。作者强调这种肿瘤的手术切除或活检的危险性,而全部放疗病人的中数生存期是10年,五年健在率是63%,一般认为可用放射治愈。生长在松果体区和异位到下丘脑的肿瘤有松果体
The pineal region and its ectopic tumors are rare brain tumors. The number of previously reported cases was small. The authors reported 25 cases, and 22 cases received radiation from a Co~(60) or 10MeV linear accelerator. Treatment, 12 deaths, according to 11 cases of autopsy findings, combined with more than 100 cases of material review reported in literature since 1960, proposed improvements in treatment. The authors emphasize the risk of surgical resection or biopsy of this type of tumor, and the median survival time for all radiotherapy patients is 10 years, and the five-year survival rate is 63%. It is generally believed that radiation therapy can be used. Tumors in the pineal region and ectopic to the hypothalamus have pineal glands
