SGO:腹膜内灌注化疗可提高卵巢癌患者生存率

2013-04-07 沈牡丹 译 医学论坛网

  3月9日,妇科肿瘤学会在洛杉矶召开的妇科肿瘤年会上,研究人员通过研究分析876名晚期卵巢癌患者的长期随访数据得出结论:与接受标准静脉内(IV)化疗的晚期卵巢癌患者相比,接受密集的腹膜内(IP)化疗的患者,生存率显著较高。研究人员建议,卵巢癌女性应该更多的接受腹膜内化疗疗,建议随访10年。   研究人员的一项中位随访期超过10年的分析显示,接受IP化疗的晚期卵巢癌患者比接受IV化疗的患者

  3月9日,妇科肿瘤学会在洛杉矶召开的妇科肿瘤年会上,研究人员通过研究分析876名晚期卵巢癌患者的长期随访数据得出结论:与接受标准静脉内(IV)化疗的晚期卵巢癌患者相比,接受密集的腹膜内(IP)化疗的患者,生存率显著较高。研究人员建议,卵巢癌女性应该更多的接受腹膜内化疗疗,建议随访10年。

  研究人员的一项中位随访期超过10年的分析显示,接受IP化疗的晚期卵巢癌患者比接受IV化疗的患者生存率延长了17%。IP组生存时间中位数超过5年(62个月),而IV组生存时间中位数为4年(51个月)。中位数的定义是接受化疗后的患者,生存时间的峰值与峰谷值的中间值。

  研究还显示,完成大部分或完成全部的推荐6周期IP化疗的女性比完成4周期或更少周期治疗的患者生存时间长。5年后得出的随访结果是,59%完成5-6周期IP化疗患者在世,33%完成3-4周期治疗的患者仍在世,而仅有18%完成1-2周期治疗的患者仍在世。不能接受完整6周期IP治疗的患者均在中途改为IV化疗,以完成剩下的周期。

  加利福尼亚州奥兰治镇南加利福尼亚凯撒医疗集团妇科肿瘤卫生组织负责人、加利福尼亚大学欧文医学院妇产科学助理教授Devansu Tewari博士说:“太多女性不能接受关于IP化疗利弊的解释,其实IP化疗可能救她们的命。要注意,IP化疗应由有经验的医生进行,以便最好的处理相应的风险与副作用。”

  每年,22000多名女性确诊为卵巢癌,15000多名女性死于卵巢癌。标准IV化疗将药物自血液流经全身,而IP化疗则直接作于腹部。此举不仅将高浓度的化疗药用得其所,还能让化疗药物吸收得更缓慢,让药物更充分的作用于暴露的癌肿。国家癌症研究所推荐将IP用于已接受最佳手术的晚期卵巢癌患者。

  IP化疗更精确,一些副作用也更强,如四肢麻木、腹痛等,一些女性因而不能完成推荐的6周期治疗。年轻女性、身体素质较好的女性或可能完成更多周期的IP。

  国家癌症研究所资助,妇科肿瘤领域的专家组成了妇科肿瘤组(GOG)。GOG从妇科肿瘤医生到护士到研究员,均致力于保持临床试验的最高标准,专注于研究女性盆腔恶性肿瘤,如卵巢癌、子宫癌、宫颈癌。

  Tewari 博士说:“毫无疑问,应向晚期卵巢癌患者普及IP化疗。患者应咨询有经验的专业妇科肿瘤医生或临床肿瘤医生以确定最好的治疗方案。起码患者应该让有IP治疗经验、能决定其是否适合IP治疗的专家来诊疗。”

原文标题:Bathing abdomen in chemotherapy gives ovarian cancer patients better chance of survival

LOS ANGELES (March 9, 2013)– Patients with advanced ovarian cancer who undergo intensive treatment with chemotherapy that bathes the abdomen are significantly more likely to live longer than those who receive standard intravenous (IV) chemotherapy, according to a study that analyzed long-term follow-up from two landmark Gynecologic Oncology Group (GOG) trials comprising 876 patients. Results of the study are being presented at the Society of Gynecologic Oncology (SGO) Annual Meeting on Women’s Cancer in Los Angeles, March 9-12.
Women who receive the treatment in the form of intraperitoneal, or IP chemotherapy are 17 percent more likely to survive longer than those who have IV chemotherapy, according to the analysis, which had a median follow-up of more than 10 years. Median survival was more than five years (62 months) for patients in the IP group and about four years (51 months) for patients in the IV group. Median is defined as the number separating the upper and lower half of a study population......
