High Dose Radiotherapy of an Esophageal Cancer Patient with Cardiac Pacemaker Implantation-A Case Report

一位植入心臟節律器之85歲男性病人被診斷出罹患食道癌。經多團隊會議討論後，病人不適合化學治療或手術，因此決定單獨使用放射治療。腫瘤位置相當接近節律器的線路，所以，即便文獻建議不要讓節律器吸收劑量超過200 cGy，節律器仍然無可避免吸收了高劑量的輻射。在放射腫瘤科和心臟內科的密切合作下，病人順利完成了放射治療。腫瘤的吸收劑量6000 cGy，而節律器的吸收劑量為5777 cGy。在治療結束後三個月的追蹤，腫瘤完全消除，節律器也無功能異常。就我們所知，在台灣，這是第一個分享如何藉由放射腫瘤科和心臟內科的密切合作，即使節律器無可避免接受高劑量輻射，仍可以成功地以放射治療來治療癌症病人的病例報告。

An 85-year-old man who had artificial pacemaker implantation was diagnosed to have esophageal cancer. The patient was ineligible for surgery or chemotherapy as the agreement of multidisciplinary tumor board. So radiotherapy alone was planned. The location of tumor is very close to the lead of pacemaker. Thus, the pacemaker absorbed high dose of radiation inevitably although the published literature strongly suggested that the pacemaker should not be in the direct field or absorb radiation dose higher than 200 cGy. Under close cooperation between the radiation oncologist and the cardiologist, the patient underwent the radiotherapy smoothly. The prescribed dose was 6000 cGy to tumor and 5777 cGy to pacemaker. The tumor got complete remission and no malfunction of pacemaker was noted at three months' follow up. To our knowledge, this is the first case report in Taiwan to demonstrate how to successfully use radiotherapy to treat a cancer patient with pacemaker implantation under the close cooperation of radiation oncologist and cardiologist.
