"Optimal" chemotherapy for advanced ovarian cancer has constantly evolved over the last 2 decades through the conduct of prospective randomized clinical trials. Because 3 such important trials have recently disclosed provocative results there are reasons to believe in the emergence of new "standard" treatment approaches for this disease towards the end of this century. 1) The Intergroup trial found a survival advantage for intraperitoneal cisplatin as compared to intravenous cisplatin following optimal debulking surgery. 2) In the EORTC-GCCG trial, which recruited patients with bulky disease at completion of primary surgery, survival was prolonged when interval debulking surgery was performed after 3 cycles of chemotherapy. 3) Paclitaxel-cisplatin was associated with a marked survival advantage in comparison with cisplatin-cyclophosphamide in the GOG trial, which enrolled suboptimally debulked patients. These trials clearly have important implications for the future management of ovarian cancer patients and from a health economy point of view: for these reasons, two of them (2 + 3) have been repeated by other groups, and results of these confirmatory trials should be available soon. There are a number of new treatment options for "Platinum-resistant" patients including docetaxel, topotecan, gemcitabine, oxaliplatin: but none of them is "optimal". An active search for new drugs in this setting remains a high priority. Finally, with the expanding knowledge of the molecular biology of cancer in general and ovarian cancer in particular, one can now start thinking of new molecular targets for treatment intervention including transmembrane tyrosine kinase growth factor receptors, matrix metalloproteinases, the vascular endothelial growth factor and so on....
在过去20年里,通过开展前瞻性随机临床试验,晚期卵巢癌的“最佳”化疗方案不断演变。由于最近有3项如此重要的试验公布了引人注目的结果,因此有理由相信在本世纪末会出现针对这种疾病的新“标准”治疗方法。1) 国际协作组试验发现,在进行最佳肿瘤细胞减灭术后,腹腔内使用顺铂比静脉使用顺铂具有生存优势。2) 在欧洲癌症研究与治疗组织-妇科癌症协作组(EORTC-GCCG)试验中,该试验招募了初次手术结束时患有大块肿瘤的患者,在化疗3个周期后进行间隔肿瘤细胞减灭术可延长生存期。3) 在妇科肿瘤学组(GOG)试验中,与顺铂-环磷酰胺相比,紫杉醇-顺铂对肿瘤细胞减灭不充分的患者具有显著的生存优势。这些试验显然对卵巢癌患者的未来治疗具有重要意义,从卫生经济学角度来看:出于这些原因,其中两项试验(2 + 3)已被其他研究小组重复进行,这些验证性试验的结果应很快就会公布。对于“铂耐药”患者有多种新的治疗选择,包括多西他赛、拓扑替康、吉西他滨、奥沙利铂:但它们都不是“最佳的”。在这种情况下积极寻找新药仍然是当务之急。最后,随着对癌症尤其是卵巢癌分子生物学认识的不断扩展,现在人们可以开始思考新的治疗干预分子靶点,包括跨膜酪氨酸激酶生长因子受体、基质金属蛋白酶、血管内皮生长因子等等……
