Abstract
[한글]

배경 및 목적: 최근에 새로운 항암제인 temozolomide가 도입되어 악성 교종 환자의 치료에 적용되고 있다. 이에 저자는 악성 교종에 대한 temozolomide 항암 치료가 procarbazine을 이용한 이전의 항암치료보다 더 효과적인지 또한 종양제거술과 방사선치료와 병행 할 때 더욱 효과가 있는지 확인하고자 본 연구를 진행하였다.

방법: 1997년 1월부터 2003년 6월까지 연세대학교 의과대학 세브란스병원에서 병리조직학상 악성교종으로 진단 후 temozolomide치료(종양제거술 후 방사선 치료 및 temozolomide 치료를 받은 환자)를 받은 22명과 PCV 치료(종양제거술 후 방사선 치료 및 procabazine 병행 항암치료를 받은 환자)를 받은 18명의 임상기록지를 후향적으로 검토 분석하였다.

결과: temozolomide치료군에서 평균 생존 기간(overall survival)은 19.5개월 이었으며 6개월 무재발생존율(6-month progression free survival)은 81.8%이었다. procarbazine치료군의 경우는 각각17.5개월, 55.6%를 보여 temozolomide치료군에서 통계적 유의성을 보이는 더 좋은 치료 결과를 보였다. 무재발생존율이 6개월 미만인 경우에도 생존율에 있어temozolomide 치료를 시행한 군에서 procarbazine치료군보다 유의하게 효과적이었다. 75%이상의 종양을 제거한 군, 7,000cGy 이상의 방사선치료를 받은 군, 4회 이상의 temozolomide치료를 받은 군에서 생존율이 높았다.

결론: 악성 교종 환자에서 항암치료를 추가하는 것이 유리할 것으로 생각되며 temozolomide항암 치료가 procabazine을 이용한 이전의 항암치료보다 더욱 효과적이고 안전하다. 특히 재발한 경우나 KPS 가 낮은 환자에서 유용하다. 또한 종양제거술 및 방사선치료와 병행할 때 temozolomide 치료가 더욱 좋은 결과를 보인다.





[영문]Object: The malignant glioma composed 50%-60% of supratentorial glial tumor and was regarded as incurable because of the high frequency of recurrence. There were remarkable advances of microsurgery, radiation therapy and chemotherapy of brain tumor last four decades. However the overall life span of patient with malignant glioma was not prolonged. Recenty, the new alkylating agent,temozolimide(TMZ), had been known to have anti-tumor activities against malignant glioma. Authors conducted clinical study using temozolomide to confirm the effectiveness and safety in supratentorial malignant glioma. Authors compared them with PCV therapy and analyzed prognosis when combined with surgical resection of tumor mass and external radiation therapy.

Method: We analyzed retrospectively the medical records of 40 patients who had been treated and pathologically diagnosed as glioblastoma or anaplastic astrocytoma at Severance Hospital from January, 1997 to June, 2003. The patients were classified into two groups: The temozolomide-treated group who underwent surgical resection of tumor followed radiotherapy and single agent temozolomide chemotherapy, enrolling 22 patients. The PCV-treated group who underwent surgical resection of tumor followed radiotherapy and procarbazine combination chemotherapy (procarbazine,CCNU,vincristine), including 18 patients.

Result: The overall survival and 6 month progression free survival(PFS) rate were 19.5 month and 81.8% in TMZ-treated group, but 17.5 month and 55.6% for PCV-treated group. In patients with PFS less than 6 month, and KPS less than 70, the survival rate of TMZ-treated group was higher than that of PCV-treated group, which had a statistical significance(p=0.0179, p=0.0025 respectively). Surgical resection of tumor mass more than 75%, followed with 7,000cGy external radiation and TMZ therapy more than four cycles had showed better prognosis

Conclusions:

1. Chemotherapy is a useful treatment modality for supratentorial malignant glioma.

2. Temozolomide therapy for supratentorial malignant glioma is more effective and safe than procarbazine therapy, especially in recurred cases and patient with low KPS .

3. Temozolomide therapy for supratentorial malignant glioma showed better prognosis when combined with surgical resection of tumor mass and external radiation therapy.
