강내 조사를 이용한 비인강압 치험2예

Two Cases of Nasopharyngeal Carcinoma Treated with Co-60 HDR ICR

저자들은 비인강암의 포괄적인 방사선 치료의 일부로서 외부 방사선 치료에 뒤이은 고선량율 강내조사를 시행하여 부작용이나 합병증 없이 종양의 완전관해를 얻었기에 문헌고찰과 함께 보고하는 바이다.

The primary treatment modality of malignant tumors of the nasopharynx is radiation therapy owing to its inaccessibility to surgical intervention. Over the last two decades there were many changes in techniques of delivery, which include the use of higher doses of radiotherapy, the use of wide radiation field, including the elective radiation of the whole neck, the combined use of brachy- and teletherapy, and the use of split-course therapy. In spite of these advances local and regional recurrences remain the major cause of death. As a boost therapy after external irradiation, high-dose-rate intracavitary irradiation using remote control afterloading system(RALS) was used in two patients. Our results were satisfactory, however, this procedure should only be performed by those who have developed enough expertise in the use of intracavitary techniques for the treatment of nasopharyngeal cancer and have a supportive team including a physicist, dosimetrist, nurse, and trained technologist.
