Pediatr Blood Cancer:中性粒细胞减少饮食与食品安全指南对小儿肿瘤患者感染率的有效性

中性粒细胞饮食(ND)是为了避免细菌进入宿主的胃肠道,减少感染。由于缺乏支持ND的证据,小儿肿瘤科医生对ND是否有用仍有争议。这项前瞻性随机对照试验评估了随机接受食品和药物管理局批准的食品安全指南(FSG)与ND加FSG在一个周期化疗期间的儿科肿瘤患者中中性粒细胞感染率的差异。

 

接受骨髓抑制性化疗的小儿肿瘤患者符合条件。中性粒细胞增多症感染是主要结果,定义为(i)发热伴中性粒细胞增多症或(ii)因临床感染和中性粒细胞增多症入院治疗。中性粒细胞增多症感染率用独立样本的Student's t检验进行比较。通过全面的病历复查确定记录的感染情况,组间采用χ2检验进行比较。

 

结果显示,150例患者被随机分配到FSG(n = 73)或ND+FSG(n = 77)。最常见的诊断为急性淋巴细胞白血病(32%)和肉瘤(32%)。两组患者发生中性粒细胞感染的比例无明显差异。FSGs 33%与ND + FSGs 35%(P = 0.78)。随机加入ND+FSGs的患者报告称,与单纯服用FSGs的患者相比,遵循饮食疗法需要更多的努力。

 

综上所述,该研究结果表明,ND对接受骨髓抑制性化疗的小儿肿瘤患者预防感染方面,与FSG相比,ND没有任何益处,患者和家属需要付出更多的努力来坚持。护理癌症患儿的机构应考虑用消炎药指南取代ND指南。

J Clin Oncol:肿瘤化疗期间,究竟该不该补充抗氧化剂?

尽管有报道称在癌症治疗期间可广泛使用膳食补充剂,但关于其安全性或有效性的相关数据很少。考虑到一些补充剂,特别是抗氧化剂,可能会降低化疗的细胞毒性,Ambrosone等人开展了一项前瞻性研究以评估补充剂的使用与乳腺癌预后之间的关系。本研究对1134位采用环磷酰胺、阿霉素和紫杉醇化疗的乳腺癌患者在化疗前和化疗过程中补充剂的应用情况进行调查。并对患者入组后6个月的复发率和存活率进行评估。结果显示在治疗前

Cell Death Dis:维生素D可增强口腔鳞状细胞癌对顺铂化疗的敏感性!

化疗药物耐受性是癌症发生发展及癌症患者死亡率提高的一个主要原因。开发提高化疗药物敏感性的安全策略是目前生物医学研究所面临的挑战。近期研究表明,补充维生素D可以降低多种癌症的患病风险。但是在化疗过程中维生素D所行使的作用目前仍不明确。研究人员发现维生素D能够促使口腔癌细胞对顺铂敏感,并可部分逆转对顺铂的耐药性。通过RNA序列研究发现LCN2(脂质运载蛋白2)是一个重要的调控因子。顺铂可以通过减少LC

Cancer Immunol Immunother:混合多肽疫苗组合多烯紫杉醇和地塞米松治疗去势抵抗性前列腺癌研究

之前人们开发了一种包含20种混合多肽(KRM-20)的新的癌症疫苗来诱导细胞毒性T淋巴细胞,从而抵抗12种不同的肿瘤相关的抗原。最近,有研究人员在II期试验中调查了是否KRM-20组合多烯紫杉醇和地塞米松能够在去势抵抗性前列腺癌(CRPC)患者中增强抗肿瘤作用。研究是一个双盲、安慰剂对照和随机II期研究,研究人员在日本10个医疗中心招募了无化疗CRPC患者。符合要求的患者以1:1的比例随机分配在K

J Clin Oncol:乳腺癌治疗对患者工作能力的影响

乳腺癌治疗的副作用会对患者的工作能力产生负面影响。既往报告缺乏详细的临床数据或与健康相关的患者报告预后(PROs),也没有前瞻性地评估治疗和相关后遗症对就业的综合影响。研究人员采用法国的一个关于I-III期乳腺癌的前瞻性的临床队列研究,来评估乳腺癌治疗对患者的工作能力的影响。该队列共招募了1874位有工作的、还有5年以上时间才退休(≤57岁)的乳腺癌患者。主要评估指标是确诊乳腺癌后2年未返回工作(

Lancet Oncol:系统化疗联合西妥昔单抗不能用于早期可切除结肠癌肝转移患者

研究发现,尽管西妥昔单抗-化疗对部分晚期不可切除肿瘤患者有效,但对于早期可切除结肠癌肝转移患者,系统化疗仍是手术后的首选治疗手段
