Phase II study of liposome-encapsulated doxorubicin plus cyclophosphamide,followed by sequential trastuzumab plus docetaxel as primary systemic therapy for breast cancer patients with HER2 overexpression or amplification

Purpose of the studyTrastuzumab combined with sequential chemotherapy with taxanes and anthracyclines as primary systemic therapy achieved high rates of pathologic complete response (pCR). Non-pegylated liposome-encapsulated doxorubicin (NPLD) has shown equal efficacy but minor cardiotoxicity compared to doxorubicin. This phase II study aimed to evaluate the activity and safety of trastuzumab with sequential chemotherapy for early or locally advanced HER2 positive BC.MethodsPreoperative treatment included NPLD (60 mg/mq iv) plus cyclophosphamide (600 mg/mq iv) every 3 weeks for 4 cycles followed by docetaxel (35 mg/mq iv) plus trastuzumab (4 mg/mq loading dose iv, then 2 mg/mq iv) weekly for 16 weeks. Primary endpoint was pCR defined as the absence of residual invasive cancer both in the breast and regional nodes. Clinical staging was exploratory evaluated by CT-PET.Results43 pts were treated from december 2005 to September 2011, 39 of them were evaluable for the purpose of study. Median age was 53 years (range: 31–78), the majority of pts had tumour stage cT2 (63%), tumour grade 3 (86%), clinical nodes involvement N+ (77%), ER positive (56%) and Ki-67 ≥20% (77%). pCR was reported in 19 (49%) of 39 pts. There was an association between Ki-67 ≥20% at baseline and pCR (p = 0.018). No cardiac toxicity or discontinuation of trastuzumab was reported. CT-PET modified the clinical stage for 10 patients showing new loco-regional lymph nodes.ConclusionsThis study confirms that integrating anti-HER2 therapy in primary treatment for HER2 positive breast cancer is active. NPLD is a safe option to minimize cardiotoxicity.     

Randomized phase II study of sunitinib versus standard of care for patients with previously treated advanced triple-negative breast cancer

PurposeThis randomized, open-label phase II study compared the efficacy of sunitinib monotherapy with that of single-agent standard-of-care (SOC) chemotherapy in patients with previously treated advanced triple-negative breast cancer (TNBC).MethodsPatients with advanced TNBC, relapsed after anthracycline- and taxane-based chemotherapy, were randomized to receive either sunitinib (37.5 mg/day) or the investigator's choice of SOC therapy. Progression-free survival was the primary endpoint.ResultsMedian progression-free survival was 2.0 months with sunitinib and 2.7 months with SOC chemotherapy (one-sided P = 0.888). Median overall survival was not prolonged with sunitinib (9.4 months) compared with SOC chemotherapy (10.5 months; one-sided P = 0.839). The objective response rate was 3% with sunitinib and 7% with SOC chemotherapy (one-sided P = 0.962).ConclusionsSunitinib monotherapy did not improve efficacy compared with SOC chemotherapy in patients with previously treated advanced TNBC, for which identification of effective treatments and therapeutic targets remains an urgent need.Trial registrationNCT00246571.     

胫骨近端关节内骨折治疗方案的选择

The effectiveness of the TAX 327 nomogram in predicting overall survival in Chinese patients with metastatic castration-resistant prostate cancer

Based on the results of TAX 327, a nomogram was developed to predict the overall survival of metastatic castration-resistant prostate cancer （mCRPC） after first-line chemotherapy. The nomogram, however, has not been validated in an independent dataset, especially in a series out of clinical trials. Thus, the objective of the current study was to validate the TAX 327 nomogram in a community setting in China. A total of 146 patients with mCRPC who received first-line chemotherapy （docetaxel or mitoxantrone） were identified. Because clinical trials are limited in mainland China, those patients did not receive investigational treatment after the failure of first-line chemotherapy. The predicted overall survival rate was calculated from the TAX 327 nomogram. The validity of the model was assessed with discrimination, calibration and decision curve analysis. The median survival of the cohort was 21 months （docetaxel） and 19 months （mitoxantrone） at last follow-up. The predictive c-index of the TAX 327 nomogram was 0.66 （95% CI： 0.54-0.70）. The calibration plot demonstrated that the 2-year survival rate was underestimated by the nomogram. Decision curve analysis showed a net benefit of the nomogram at a threshold probability greater than 30%. In conclusion, the present validation study did not confirm the predictive value of the TAX 327 nomogram in a contemporary community series of men in China, and further studies with a large sample size to develop or validate nomograms for predicting survival and selecting therapies in advanced prostate cancer are necessary.     

Four‐year allograft survival in a highly sensitized combined liver–kidney transplant patient despite unsuccessful anti‐HLA antibody reduction with rituximab,splenectomy, and bortezomib

Although donor‐specific lymphocytotoxic antibodies are regarded as a contraindication for kidney transplantation (KTx), the data available for liver or combined liver or kidney transplantation (cLKTx) are scarce. Here, we report a case of a highly sensitized young man receiving his sixth liver and second kidney graft. Multiple anti‐HLA antibodies were present at the time of transplantation. As a result of suspected antibody‐mediated graft damage, the patient was treated with rituximab, plasmapheresis, intravenous immunoglobulins, splenectomy, and bortezomib to decrease the antibody production. So far, patient and allograft survival has reached 4 years despite failure to achieve a permanent reduction of anti‐HLA antibodies, and particularly nondonor directed antibodies.     

ICUD-EAU International Consultation on Bladder Cancer 2012: Non–Muscle-Invasive Urothelial Carcinoma of the Bladder

Context

Our aim was to present a summary of the Second International Consultation on Bladder Cancer recommendations on the diagnosis and treatment options for non–muscle-invasive urothelial cancer of the bladder (NMIBC) using an evidence-based approach.

Objective

To critically review the recent data on the management of NMIBC to arrive at a general consensus.

Evidence acquisition

A detailed Medline analysis was performed for original articles addressing the treatment of NMIBC with regard to diagnosis, surgery, intravesical chemotherapy, and follow-up. Proceedings from the last 5 yr of major conferences were also searched.

Evidence synthesis

The major findings are presented in an evidence-based fashion. We analyzed large retrospective and prospective studies.

Conclusions

Urothelial cancer of the bladder staged Ta, T1, and carcinoma in situ (CIS), also indicated as NMIBC, poses greatly varying but uniformly demanding challenges to urologic care. On the one hand, the high recurrence rate and low progression rate with Ta low-grade demand risk-adapted treatment and surveillance to provide thorough care while minimizing treatment-related burden. On the other hand, the propensity of Ta high-grade, T1, and CIS to progress demands intense care and timely consideration of radical cystectomy.     

局部进展期胃癌术前化疗的疗效分析

目的 探讨局部进展期胃癌术前化疗的疗效及安全性,以及影响术前化疗胃癌患者复发死亡的因素.方法 回顾性分析2007年7月至2011年6月间复旦大学附属中山医院肿瘤内科收治的49例局部进展期胃癌患者的临床资料.采用Cox比例风险模型来分析新辅助化疗患者复发死亡的危险因素.结果 其中48例患者化疗后在术前接受了影像学评估,术前化疗的有效率和疾病控制率分别为33.3％(16/48)和93.8％(45/48);另有1例因在化疗期间胃穿孔行急诊手术而未接受影像学评估.治疗后89.8％(44/49)的患者获得根治手术,其中90.9％的患者(40/44)接受了D2淋巴结清扫术.术后淋巴结转阴率为30.6％(15/49);术后病理有反应32例,其中2例获得完全病理缓解.术前化疗期间血液学毒性反应主要为白细胞下降,非血液学毒性反应主要为恶心呕吐,以1～2级为主.49例患者平均住院时间为11.6 d,其中2例(4.1％)分别因术后胰漏和胰周渗液而延长了住院时间.49例患者均接受了术后随访,中位随访时间为21.6个月,中位无复发生存期为29.6个月(95％CI:24.0～35.2),中位总生存期为34.6个月(95％CI:29.8～39.4).多因素预后分析显示,影像学疗效(P.=0.038,RR=0.168,95％CI:0.031～0.904)和病理反应(P=0.007,RR=0.203,95％CI:0.064～0.642)是影响本组患者术后复发死亡的独立因素.结论 术前化疗对于局部进展期胃癌具有较高的疾病控制率和R0切除率;影像学疗效和病理反应是影响局部进展期胃癌术前化疗患者最重要的预后指标.
