摘要
Background This phase II study evaluated the efficacy and toxicity of combination chemotherapy with nedaplatin and 5-fluorouracil (5-FU) for metastatic esophageal squamous cell carcinoma. %26lt;br%26gt;Methods Eligibility criteria included squamous cell carcinoma with organ metastasis, ECOG performance status (PS) 0-2, %26lt;= 75 years, measurable disease, and adequate organ function. Chemotherapy consisted of 5-FU (800 mg/m(2)/day) on days 1-5 and a 2-h infusion of nedaplatin (90 mg/m(2)) on day 1, repeated every 4 weeks. Therapy was continued until disease progression or intolerable adverse events. The primary end point was response rate. Secondary end points included overall survival, progression-free survival, and toxicities. %26lt;br%26gt;Results Forty-two patients (39 men, 3 women; median age 59 years; range 44-70 years) were enrolled. Twenty-one, 21, and 0 patients had PS 0, 1, and 2, respectively. 23, 6, 3, and 18 patients had a history of surgical resection, radiotherapy, adjuvant chemotherapy, and no therapy, respectively. Among the 38 eligible patients, 1 and 14 complete and partial responses were observed, respectively; the overall response rate was 39.5 % (90 % confidence interval: 26.1-54.1 %). The median survival time was 8.8 months. The one-year survival rate was 32.9 %. Grade 4 neutxopenia and thrombocytopenia were observed in 7 and 2 % of 41 patients, respectively. Grade 3 nausea, diarrhea, and stomatitis were observed in 12, 2, and 2 %, respectively. %26lt;br%26gt;Conclusion Combination therapy with nedaplatin and 5-FU is highly active and well tolerated in metastatic or recurrent esophageal squamous cell cancer and is therefore a chemotherapy option for esophageal squamous cell carcinoma.
