Cisplatin-based multiple-drug chemotherapy is currently considered the most effective treatment for advanced and metastatic urothelial cancers. We treated 15 patients with locally advanced urothelial cancers of the upper urinary tract using the cisplatin-based multiple-drug regimen in a neoadjuvant setting. The regimens administered were: M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin); MEC (methotrexate, etoposide and cisplatin), or M-VEC (methotrexate, vinblastine, epirubicin and cisplatin). Total nephroureterectomy was performed in all patients and response was evaluated pathologically Of 15 patients 2 (13%) achieved a pathological complete response, 6 (40%) a pathological partial response, for an overall response rate of 53% (95% confidence limits 29-77%). The median durations of response were 54 months for patients with a pathological complete response and 15.5 months for patients with a pathological partial response. One of six patients with a pathological partial response and 4 of 7 with no remission died of cancer. While a positive relationship between the pathological response and prognosis was observed, adequate follow-up is needed to assess the ability of neoadjuvant chemotherapy to improve the prognosis of patients with locally advanced urothelial cancer of the upper urinary tract.
以顺铂为基础的多药化疗目前被认为是晚期和转移性尿路上皮癌最有效的治疗方法。我们在新辅助治疗中使用以顺铂为基础的多药方案治疗了15例上尿路局部晚期尿路上皮癌患者。所采用的方案为:M-VAC(甲氨蝶呤、长春碱、阿霉素和顺铂);MEC(甲氨蝶呤、依托泊苷和顺铂),或M-VEC(甲氨蝶呤、长春碱、表柔比星和顺铂)。所有患者均接受了根治性肾输尿管切除术,并进行了病理反应评估。15例患者中,2例(13%)达到病理完全缓解,6例(40%)达到病理部分缓解,总缓解率为53%(95%置信区间29-77%)。病理完全缓解患者的中位缓解持续时间为54个月,病理部分缓解患者为15.5个月。6例病理部分缓解患者中有1例,7例未缓解患者中有4例死于癌症。虽然观察到病理反应与预后之间存在正相关关系,但需要进行充分的随访以评估新辅助化疗改善上尿路局部晚期尿路上皮癌患者预后的能力。
