目的 探讨转移性去势抵抗性前列腺癌(metastatic castration-resistant prostate cancer,mCRPC)患者多西他赛化疗后总生存期(overall survival,OS)的影响因素. 方法 回顾性分析2005年11月至2011年9月接受多西他赛化疗的115例mCRPC患者的临床资料.确诊年龄49~81岁,中位数为65岁.确诊时PSA值2.9~4000.0μg/L,中位数为100.0μg/L.Gleason评分≤7分26例,≥8分89例.化疗时年龄51~82岁,中位数为68岁.化疗前基线PSA值0.8~4066.4μg/L,中位数为90.5μg/L.基线血红蛋白(Hb)浓度68~150 g/L,中位数为121 g/L.基线碱性磷酸酶(alkaline phosphatase,ALP)浓度为33~1083 U/L,中位数为110 U/L.激素敏感时间2~114个月,中位数为23个月.115例均有骨转移,其中16例伴有内脏器官转移.接受多西他赛化疗1~16个周期,平均6个周期.患者均进行随访,对可能影响化疗疗效的因素进行单因素生存分析,并将其中有统计学意义的指标纳入多因素分析.生存函数分析采用Kaplan-Meier法,采用Logrank法进行显著性检验. 结果 本组115例随访2~74个月,中位时间为45个月.87例死亡,28例生存.中位OS为(17.0±1.9)个月.单因素生存分析结果显示,化疗前PSA值、基线Hb浓度、ALP浓度、乳酸脱氢酶(lactate dehydrogenase,LDH)浓度、谷氨酰转肽酶(gamma-glutamyl transpeptidase,GGT)浓度、ECOG评分、激素敏感时间及化疗周期数与OS相关(P<0.05).Cox模型多因素分析显示,基线ALP≥110 U/L、Hb<110 g/L、激素敏感时间<23个月及化疗周期数<6个是较短OS的独立预后因素(P<0.05). 结论 化疗前基线ALP浓度、Hb浓度、激素敏感时间及化疗周期数是mCRPC患者多西他赛化疗后OS的独立预后因素.  相似文献

目的:研究雌二醇氮芥/多西他赛/泼尼松(Estramustine/Prednisone/Docetaxel,E/D/P)联合治疗多西他赛/泼尼松(Prednisone/Docetaxel,D/P)失败后转移性去势抵抗性前列腺癌(mCRPC)患者的的疗效和安全性。方法:2005年11月~2015年7月我院40例D/P治疗失败的mCRPC患者接受了E/D/P联合治疗方案。将血清PSA水平降低50%作为主要终点。并对其化疗毒性进行评价。结果:所有患者接受了185个周期的E/D/P治疗。40例均符合安全性评价,35例符合疗效评价。总中位无生化进展生存期为17.1周,中位总生存期为85.7周,62.8%(22/35)的患者有治疗应答,E/D/P应答者的总生存期明显优于E/D/P无应答者(104.6周vs.65.1周)。尽管在15%的患者中有3~4级的嗜中性粒细胞减少症,但这种联合治疗方案总体上是可以耐受的。结论:回顾性资料表明,雌二醇氮芥能有效逆转多西他赛的耐药性,延长生存期。E/D/P联合治疗D/P失败后的mCRPC患者的治疗效果明显,且毒性可接受。  相似文献

内分泌治疗是进展期前列腺癌的主要治疗方法。然而,大部分患者在12~18个月的治疗后将逐渐发展成为去势抵抗性前列腺癌(CRPC),传统化学治疗对其疗效欠佳,其中位生存期仅为1年左右。虽然目前多西他赛联合泼尼松已经成为CRPC治疗的一线化疗方案,然而CRPC的治疗策略的选择仍然是临床难题。目前可供选择的CRPC治疗方案包括肾上腺合成抑制治疗、免疫治疗、靶向治疗以及化学治疗等,本文结合近年来文献综述CRPC的治疗策略。  相似文献

随着人们生活方式的改变以及前列腺特异性抗原筛查的普及,前列腺癌的诊断和治疗更为重要。尽管内分泌治疗对于进展性前列腺癌有治疗效果,但最终会进展为去势抵抗性前列腺癌,从而严重影响患者的生存期。近年来,研究者对于去势抵抗性前列腺癌的治疗做出了巨大努力,包括新的内分泌治疗、细胞毒性的化学治疗、免疫治疗以及以骨转移为靶点的治疗方式逐步问世,本文就这些新的治疗进展进行综述,以期为临床医生及进展性前列腺癌患者提供更多的治疗选择,延长总体生存期,提高生活质量。  相似文献

In the past 5 years, the treatment and understanding of metastatic castrate resistant prostate cancer (CRPC) have improved dramatically. Our understanding of the mechanisms of castration resistance has allowed for the development of new drugs to target prostate cancer, and our understanding of genetic mutations may give us new tools with which to more accurately diagnose and be able to predict the course of this heterogeneous disease. This article summarizes the recent advances in the understanding of the development of CRPC, as well as the new drugs and targets, which have evolved from this basic research.  相似文献

BackgroundThe administration of docetaxel chemotherapy is one therapeutic option to delay disease progression and increase overall survival in metastatic castration resistant prostate cancer (mCRPC). However, about 15% of patients are primary resistant to chemotherapy and hence would benefit from an alternative mCRPC treatment. Despite intensive research, there are no robust clinical validated biomarkers to predict mCRPC therapy response. Thus, the aim of the study was to determine KDM5D expression in archival radical prostatectomy specimens of patients medicated with docetaxel at time of mCRPC development in order to correlate KMD5D expression with treatment response.MethodsWe used in situ hybridization (ISH) (RNA scope 2.5 HD) to determine KDM5D expression in tissue samples of 28 prostate cancer patients. KDM5D status was correlated to chemotherapy response (PSA and radiographic response).ResultsData revealed that KDM5D is significantly overexpressed in tumor cells (P<0.0001) but also in benign cells (P<0.02) of those patients who responded to chemotherapy compared to non-responders.ConclusionsTo summarize, KDM5D is a promising novel biomarker predicting response to docetaxel chemotherapy already at the time of localized disease and thus potentially avoiding metastatic biopsies in the mCRPC stage of disease.  相似文献

Several new compounds are now available for castration resistant prostate cancer (CRPC). Individual costs range between $40,000 and $93,000 with mean survival extensions from 2.4 to 4.8 months. Currently, it remains unclear how patients with prostate cancer (PCa) value the effect of these therapies in the setting of CRPC.

Objective

To assess patient understanding of core cancer concepts, opinions on the cost and overall benefit of CRPC drugs, whether out-of-pocket costs would change opinions and whether patients would ultimately opt out of CRPC drug treatment for an end-of-life (EOL) premium.

Patients and methods

We conducted a qualitative survey among patients with various PCa states ranging from active surveillance to CRPC and from various familial, financial and educational demographics. Through a series of hypothetical scenarios, we extrapolated opinions on CRPC drug value, efficacy and monetary worth. We assessed patient willingness to accept an EOL ($50,000) premium in lieu of CRPC drug treatment. Statistically, chi-squared analysis and Fisher’s exact test were used when appropriate.

Results

In total, 103 patients completed the questionnaire, one-half of whom did not understand “advanced PCa” state and more than one-third of the concept of palliative care despite multiple meetings with Urologists. Patients willingness-to-pay and proposed drug value was higher than that accepted by government when government funded, with costs exceeding $250,000 per person, but lower than that accepted by government when self-funded. A majority (60%) would accept/consider the EOL premium in the setting of CRPC. Patients with higher education were more skeptical about CRPC drug value and more likely to accept the EOL premium (P = 0.003.)

Conclusion

Patients have an incomplete understanding of their own disease prognosis and its therapeutic options. This ultimately influences patient decision-making. Education, income and out-of-pocket costs diminished opinion of CRPC drugs considerably. As such, an EOL premium should be considered in subsets of patients.  相似文献

Background

The optimal number of 3-wk docetaxel plus prednisone (DP) cycles for metastatic castration-resistant prostate cancer (mCRPC) is unclear.

Objective

A retrospective analysis of two clinical trials was performed to evaluate the association of the number of cycles with overall survival (OS).

Design, setting, and participants

An exploratory analysis compared outcomes of 332 men who received DP in the TAX-327 trial, which stipulated up to 10 cycles, and 220 men who received DP in CS-205, a randomized phase 2 trial comparing DP plus AT-101 (bcl-2 inhibitor) versus DP plus placebo, which allowed up to 17 cycles.

Measurements

Patients who completed 10 cycles of DP without progression in both trials were included. Men in both arms of CS-205 were combined for analysis, as no significant differences in outcomes were observed. OS was estimated from the date of cycle 10 docetaxel infusion.

Results and limitations

The number of men receiving 10 cycles was similar (p = 0.26) in the two trials (166 [50.0%] in TAX-327 vs 99 [45.0%] in CS-205; the latter group received a median of five additional cycles). Six- and 12-mo estimated survival after cycle 10 was 92.2% (95% confidence interval [CI], 86.9-95.4%) and 74.6% (CI, 67.2-80.5%) in TAX-327, compared with 92.8% (CI, 85.5-96.5) and 63.4% (CI, 51.8-72.9%) in CS-205. Subanalyses suggested that <10 cycles may have a negative impact and prostate-specific antigen (PSA) declines at cycle 10 may carry a favorable impact. The significance of continued PSA declines up to 17 cycles is unclear. Limitations of a retrospective analysis apply.

Conclusions

A survival benefit was not detected with >10 cycles of DP in men with mCRPC in this retrospective hypothesis-generating analysis.  相似文献
