수술중 방사선 치료는 우리나라와 같이 위암환자가 많은 경우에 그 이용 범위가 넓고 특히 국소적으로 진행된 경우에 효과가 있으므로 앞으로 그 이용가치가 높다고 하겠다. 저자들은 국소적으로 진행된 두 명의 위암환자에서 일반외과, 마취과, 치료방사선과가 합동으로 수술중 치료를 시행 하였기에 문헌 고찰과 함께 보고하는 바이다.
Stomach cancer is the most popular tumor in Korea but the prognosis following extensive surgery and chemotherapy has not improved for many years. Conventional external radiotherapy also has some limitation, namely, a cancerocidal dose can not be delivered to tumors because of low radiation tolerance of adjacent critical sensitive organs. In order to overcome these limitations of curative surgery and external radiotherapy, intraoperative radiotherapy was proposed in many centers and the results were excellent. We treated two cases of locally advanced gastric cancers with IORT by using NEC 18 MeV Linear Accelerator after standard subtotal resection of the stomach. After treatment, the patients are in good conditions so far, but in order to evaluate the effectiveness of IORT, a study will be performed on the survival rates between patients treated by IORT and those treated by surgery alone.
