我们根据临床需要研制了食管腔内灌注器，能将高浓度抗癌药物长时间存留于病变食管腔内，对肿瘤产生直接杀伤作用，且不易引起全身毒性反应，术前使用还可减少术后转移及复发机会。１９９７年１月至６月临床试用２７例，近期效果良好，有效率７３３％。肿瘤组织内最高药... We have developed an esophageal lumen perfusion device based on clinical needs. It can store high-concentration anticancer drugs in the esophageal cavity for a long period of time. It has a direct killing effect on tumors and is not likely to cause systemic toxicity. Preoperative use can also reduce Postoperative metastasis and recurrence opportunities. From January to June 1997, 27 cases were clinically tested. The recent results were good and the effective rate was 73. 3%. The highest drug in tumor tissue...
