전이성 또는 재발성 식도암에 대한 Cisplatin , Etoposide 및 5 - Fluorouracil ( PEF ) 복합화학요법의 치료 효과

Esophageal cancer is widely disseminated in more than 80% of patients at the time of diagnosis and the prognosis of advanced esophageal cancer is dismal with a median survival of 5 to 8 months. Therefore, systemic chemotherapy has assumed an important role in the treatment of these patients. Among various combination chemotherapy regimens, the combination of cisplatin and 5-fluorouracil has been one of the most effective for esophageal cancer because of their synergism. Etoposide, although reported ineffective as a single agent, has been shown to be synergistic with cisplatin in vitro and in vivo. So, we conducted a phase 2 trial to evaluate the effect of a combination of cisplatin, etoposide and 5- FU (PEF) in patients with metastatic or recurrent esophageal cancer. Thirty-four patients with measurable lesion(s) received cisplatin (20㎎/㎡ i.v. Day 1~5), etoposide (100㎎/㎡ i.v. Day 1, 3 & 5) and 5-FU (800㎎/㎡ continuous i.v. for 12 hours, Day 1~5). Of 30 evaluable patients, 1(3.3%) had a complete response and 11(37%) had partial responses. The median duration of response was 29 weeks. The overall median survival was 34 weeks and the survival time in the responders was longer significantly than that of the non-responders. There was no significant prognostic factor influencing the response rate. Among total 135 cycles of chemotherapy, leukopenia was observed in 36% and thrombocytopenia in 4%. There was no treatment-related death. Main non-hematologic toxicities were neurotoxicity (17%), nephrotoxicity (3%), and stomatitis (10%) and diarrhea (10%). All the toxicities were mild and well tolerated. Conclusion: A combination chemotherapy of cisplatin, etoposide and 5-FU (PEF) was effective and well tolerated in patients with metastatic or recurrent esophageal cancer.
