单次高剂量化疗周期可产生超过50%的反应率。然而,5年无病生存率(DFS)为15-20%。延长DFS的一个最重要的预测指标是达到完全缓解(CR)。增加达到完全缓解的患者比例可以提高无病生存期。对诱导化疗至少有部分反应(PR)的转移性乳腺癌患者接受了三个单独的高剂量化疗周期,包括外周血祖细胞支持和G-CSF。第一次强化为紫杉醇(825 mg/ m2),第二次强化为美伐兰(180 mg/ m2),第三次强化为环磷酰胺6000 mg/ m2 (1500 mg/ m2 /day× 4),硫替帕500 mg/ m2 (125 mg/ m2 /day× 4)和卡铂800 mg/ m2 (200 mg/ m2 /day× 4)(CTCb)。61名妇女参加了研究,其中60名完成了所有三个周期。紫杉醇输注后,大多数患者出现可逆性,主要是感觉多神经病变。在30例可测量疾病的患者中,12例转化为CR, 9例转化为PR*, 5例进一步PR,总有效率为87%。中毒死亡率为5%。没有患者在研究中取得进展。30%的患者无进展,中位随访31个月(1-43个月),总生存率为61%。三个连续的高剂量化疗周期是可行的,并导致高有效率。挑战仍然是维持反应,并提供机会评估消除最小残留疾病的战略。
A single high-dose cycle of chemotherapy can produce response rates in excess of 50%. However, disease-free survival (DFS) is 15–20% at 5 years. The single most important predictor of prolonged DFS is achieving a complete response (CR). Increasing the proportion of patients who achieve a complete response may improve disease-free survival. Women with metastatic breast cancer and at least a partial response (PR) to induction chemotherapy received three separate high-dose cycles of chemotherapy with peripheral blood progenitor support and G-CSF. The first intensification was paclitaxel (825 mg/m 2), the second melphalan (180 mg/m 2) and the third consisted of cyclophosphamide 6000 mg/m 2 (1500 mg/m 2/day× 4), thiotepa 500 mg/m 2 (125 mg/m 2/day× 4) and carboplatin 800 mg/m 2 (200 mg/m 2/day× 4)(CTCb). Sixty-one women were enrolled and 60 completed all three cycles. Following the paclitaxel infusion most patients developed a reversible, predominantly sensory polyneuropathy. Of the 30 patients with measurable disease, 12 converted to CR, nine converted to a PR*, and five had a further PR, giving an overall response rate of 87%. The toxic death rate was 5%. No patient progressed on study. Thirty percent are progression-free with a median follow-up of 31 months (range 1–43 months) and overall survival is 61%. Three sequential high-dose cycles of chemotherapy are feasible and resulted in a high response rate. The challenge continues to be maintenance of response and provides the opportunity to evaluate strategies for eliminating minimal residual disease.
