Clinical features and prognostic factors for extracranial oligometastatic breast cancer in China

Evidence of an oligometastatic state in metastatic breast cancer (MBC) is relatively limited. The aim of our study was to investigate the clinical features and prognostic factors for extracranial oligometastatic breast cancer and to identify the best treatment approaches in this select population. Fifty postoperative inpatients diagnosed with extracranial oligometastatic breast cancer at the National Cancer Center in China between 2009 and 2014 were consecutively enrolled. Oligometastatic breast cancer was defined as MBC with three or fewer metastatic lesions confined to one organ; de novo Stage IV disease and local-regional recurrence were excluded. The median progression-free survival (PFS) and overall survival (OS) times were 15.2 and 78.9 months, respectively, and the 2-year PFS and 5-year OS rates were 40% and 58%, respectively. First-line treatment approach with standard systemic treatment + surgical resection for all metastatic lesions was an independent prognostic factor for prolonged PFS (hazard ratio = 0.32; 95% confidence interval [CI], 0.14-0.73; P = .006) and OS (hazard ratio = 0.35; 95% CI, 0.14-0.86; P = .022). Subgroup analysis showed that patients with a disease-free interval (DFI) ≥24 months, one metastatic lesion or the hormone receptor (HR) + subtype were more likely to get benefit from resection. Patients with oligometastatic breast cancer have a relatively good prognosis. Surgical resection for metastatic lesions could significantly improve PFS and OS. Further prospective research is warranted to confirm the results and to develop biomarkers for better patient selection.     

重组人血管内皮抑制素和沙利度胺联合化疗治疗转移性结直肠癌的临床观察

目的 观察重组人血管内皮抑制素（恩度）、沙利度胺与细胞毒药物联合治疗晚期结直肠癌的疗效和安全性。方法 研究纳入47例2006年1月至2013年1月于中国医学科学院肿瘤医院接受恩度、沙利度胺联合细胞毒药物治疗的转移性结直肠癌患者。分别按照实体瘤的疗效评价标准（RECIST）1.0和国立癌症研究所毒性判定标准（NCI-CTC）4.0评价疗效和毒副反应,同时随访其生存情况。具体给药方案：恩度15 mg/d,加入生理盐水500 ml静脉滴注,d1~d10;沙利度胺150 mg或200 mg,每晚睡前顿服,d1~d10;14 d为1周期。与恩度和沙利度胺联用的化疗方案均为双周方案,包括奥沙利铂+氟尿嘧啶类药物（18例）,奥沙利铂+雷替曲塞（1例）,伊立替康+氟尿嘧啶类药物（26例）及伊立替康+雷替曲塞（2例）。结果 一线、二线、三线及三线以上接受含恩度+沙利度胺联合化疗方案者的中位生存期依次为26.1（95%CI： 21.9~30.2）、15.3（95%CI：9.5~21.0）和7.5（95%CI：4.2~10.7）个月,中位无进展生存期依次为：11.1（95%CI：8.6~13.7）、7.9（95%CI：4.7~11.2）和4.2（95%CI：1.5~7.0）个月,有效率依次为63.1%、37.5%和16.7%,疾病控制率依次为84.2%、68.7%和66.7%。全组的常见不良反应多为1~2级,包括白细胞减少、中性粒细胞减少、贫血、恶心和呕吐,3、4级毒副反应包括中性粒细胞减少（8.5%）、血小板减少（6.4%）、恶心（4.3%）、呕吐（4.3%）、便秘（4.3%）、疲乏（2.1%）和周围神经毒性（2.1%）。结论 恩度、沙利度胺联合细胞毒药物对初治和复治的转移性结直肠癌患者有较好的疗效及安全性。
