1978년 1월부터 1985년 12월까지 경희의대 부속병원 치료방사선과에서 상행정맥 증후군으로 방사선치료를 받은 환자 21명을 대상으로, 분할조사방법과 치료 총선량에 따른 초기종상의 완화와 치료에 대한 반응 및 생존율을 관찰하여 다음과 같은 결과를 얻었다. 1) 고 선량 치료군에서는 $54.5\%(6/11)$에서 치료 $1\~2$일 후에 증상의 판화를 보였으며 $81.7\%(9/11)$에서 치료 $3\~4$일내에 증상의 완화를 나타내었다. 2) 일반분할조사가 각각 $29\%,\;50\%$를 나타낸 것보다는 월등히 많은 환자에서 조기에 증상완화를 보였으나 두 군간의 생존율에는 유의한 차이가 없었다. 3) 치료후의 반응 판정에서는 총 선량 3,000c0y이상 치료한 군에서는 대부분이 반응을 나타냈으나, 3,000cGy이하를 치료한 군의 5예에서는 모두 반응을 나타내지 않았다. To access the result of radiation therapy for 8 years experiences, 21 patients who were treated with superior vena cava syndrome had been analysed according to dose fractionation and total dose. The results are as follows; 1. In high fractionate dose group, six of eleven patients $(54.5\%)$ exhibited relief of symptoms in 1-2 days, and additional three patients of nine $(81.7\%)$ within 34 days, while standard fractionated dose treatment is not effective to achieve initial relief of symptoms. 2. Graded response by total dose was correlated with total dose rather than dose fractionation. 3. Overall one year survival rate with superior vena cava syndrome was $9.1\%$ and mean survival was 4.2 months.

The normal intracranial structures are relatively resistant to therapeutic radiation, but may react adversely in a variety of ways, and the damage to nerve tissue may be slow in making its appearance, and once damage has occurred the patient recovers slowly and incompletly. Therefore, it is important to consider the possibility of either recurrent tumor or late adverse effect in any patient who has had radiotherapy. The determination of morphological/pathological correlation is very important to the rapeutic radiologist who used CT scans to define a treatment volume, as well as to the clinician who wishes to explain the patient's clinical state in terms of regress, progression, persistence, or recurrence of tumor or radiation-induced edema or necrosis. The authors are obtained as following results; 1. The field size(whole CNS, large, intermediate, small field) was variable according to the location and extension of tumor and histopathologic diagnosis, and the total tumor dose was 4,000 to 6,000 rads except one of recurred case of 9.100 rads. The duration of follow up CT scan was from 3 months to 5 year 10 months. 2. The histopathologic diagnosis of 9 cases were glioblastoma multiforme(3 cases), pineal tumor (3), oligodendroglioma (1), cystic astrocytom (1), pituitary' adenoma (1) and their adverse effects after radiation therapy were brain atrophy (4 cases), radiation necrosis(2), tumor recurrence with or without calcification (2), radiation-induced infarction(1). 3. The recurrent symptoms after radiation therapy of brain tumor were not always the results of regrowth of neoplasm, but may represent late change of irradiated brain. 4. It must be need that we always consider the accurate treatment planning and proper treatment method to reduce undesirable late adverse effects in treatment of brain tumors.
