The role of chemotherapy in locally advanced or metastatic gastric cancer has been controversial, but chemotherapy has recently been shown to relieve tumor-related symptoms, improve quality of life and prolong survival when compared with best supportive care. Furthermore, palliative chemotherapy is also cost-effective. "Second-generation" combination chemotherapy regimens were developed in the 1980s with high activity in advanced or metastatic gastric cancer (EAP, FAMTX, PELF, ECF). In randomized studies, EAP demonstrated no difference in activity but a significantly higher overall toxicity and toxic death rate than FAMTX, and the ECF (epirubicin, cisplatin, 5-fluorouracil) regimen gave a survival and response advantage, tolerable toxicity, better quality of life and was more cost-effective than FAMTX.
Sixty patients with locally advanced or metastatic gastric cancer were treated with the ECF regimen (21 weeks of 5-fluorouracil given by continuous infusion through a central line at 200 mg/m2 for 24-hr combined with cisplatin at 60 mg/M2 iv and epirubicin at 50 mg/M2 iv beginning on day 1 and repeated every 3 weeks for 8 courses). There were 42 males and 18 females, with a median age of 64 years (range, 40-74). The median performance status was 1. The histologic type was adenocarcinoma in 44 patients and undifferentiated carcinoma in 16 (27%). Three patients had locally advanced disease (5%) and 57 had metastatic disease (95%). Seven patients (12%) had received prior chemotherapy for advanced disease.
All patients were assessable for toxicity and 55 for response (5 had insufficient treatment). Toxicity was mild or moderate, and there was no toxic death. Incidence of WHO toxicity > or = 2 was nausea and vomiting in 3%, mucositis in 3%, leukopenia in 7%, anemia in 3%, and thrombocytopenia in 2%. Port-a-Cath toxicity was thrombosis in 4, dislocation in 2 and infection in 3 patients. Seven complete responses and 13 partial responses (overall response rate, 36%) were achieved, with a response rate of 39% in untreated and 17% in pretreated patients. Nine patients (16%) had stable disease and 26 (47%) progressive disease. Most patients felt symptomatically improved on ECF.
Our study confirms that the ECF regimen has a favorable pattern of toxicity and is feasible on an outpatient basis. However, it did not confirm the high response rate reported in other phase II trials.
化疗在局部晚期或转移性胃癌中的作用一直存在争议,但最近研究表明,与最佳支持治疗相比,化疗可缓解肿瘤相关症状、提高生活质量并延长生存期。此外,姑息性化疗还具有成本效益。20世纪80年代研发出了“第二代”联合化疗方案,对晚期或转移性胃癌具有较高活性(EAP、FAMTX、PELF、ECF)。在随机研究中,EAP在活性方面无差异,但总体毒性和毒性死亡率显著高于FAMTX,而ECF(表柔比星、顺铂、5-氟尿嘧啶)方案在生存期和缓解方面具有优势,毒性可耐受,生活质量更好,且比FAMTX更具成本效益。
60例局部晚期或转移性胃癌患者接受ECF方案治疗(通过中心静脉持续输注5-氟尿嘧啶21周,剂量为200mg/m²,持续24小时,联合顺铂60mg/M²静脉注射和表柔比星50mg/M²静脉注射,从第1天开始,每3周重复1次,共8个疗程)。男性42例,女性18例,中位年龄64岁(范围40 - 74岁)。中位体能状态为1。组织学类型为腺癌44例,未分化癌16例(27%)。3例为局部晚期疾病(5%),57例为转移性疾病(95%)。7例患者(12%)曾因晚期疾病接受过化疗。
所有患者均可评估毒性,55例可评估缓解情况(5例治疗不足)。毒性为轻度或中度,无毒性死亡。世界卫生组织(WHO)毒性≥2级的发生率为:恶心呕吐3%,黏膜炎3%,白细胞减少7%,贫血3%,血小板减少2%。植入式静脉输液港毒性表现为4例血栓形成,2例移位,3例感染。获得7例完全缓解和13例部分缓解(总缓解率36%),未治疗患者的缓解率为39%,曾接受治疗患者的缓解率为17%。9例患者(16%)病情稳定,26例(47%)病情进展。大多数患者在接受ECF治疗后症状有所改善。
我们的研究证实,ECF方案具有良好的毒性模式,且在门诊可行。然而,本研究未证实其他II期试验报道的高缓解率。
