Eur Raidol:肝脏<1cm的异常强化结节,如何判断良恶性?

本研究旨在验证钆塞酸肝脏MRI中亚厘米(≤1 cm)动脉性异常强化和肝胆管异常低信号病变(SAELs)评估肝细胞肝癌(HCC)风险的意义,并将结果发表在Eur Raidol上。

本研究旨在验证钆塞酸肝脏MRI中亚厘米(≤1 cm)动脉性异常强化和肝胆管异常低信号病变(SAELs)评估肝细胞肝癌(HCC)风险的意义,并将结果发表在Eur Raidol上。

SAEL是指钆塞酸增强MRI中变现为亚厘米富血供结节,肝胆期呈低信号。本研究共纳入了46例患者包含52处SAEL病变。HCC最终诊断由病理学却或在随访中呈现>1 cm并具有典型肝癌影像学特征的结节。评价SAEL的恶性率及支持HCC的影像学表现。

SAEL的恶性率为57.7% (30/52)。在诊断中,所有有进展为HCC的SAEL均进行了根除性治疗。恶性SAEL发生静脉期或动态晚期廓清较良性SAEL更常见(57.7% vs. 30.6%; P = 0.01)。如果SAEL出现廓清认为是HCC,敏感性、特异性和阳性预测值分别为83.3%、50%、69.4%。

本研究表明,在有患HCC风险的患者中,钆塞酸增强MRI中的SAEL具有高度恶性潜能。然而,密切的观察有助于孤立性SAEL的诊断。廓清现象有助于提示为恶性。

拜耳公司宣布,国家食品药品监督管理总局(CFDA)批准口服多激酶抑制剂瑞戈非尼(商品名:拜万戈)用于既往接受过索拉非尼治疗的肝细胞癌(HCC)患者。关键性III期RESORCE试验结果显示,与安慰剂相比,瑞戈非尼可使总生存期得到显著性改善。索拉非尼后序贯使用瑞戈非尼治疗可使患者的中位总生存期达26个月。瑞戈非尼是在华首个获批用于HCC二线治疗的新药,此次批准拓展了经索拉非尼治疗出现进展后使用瑞戈非

Hepatology:雄激素受体过度表达与AR-mTOR在肝细胞癌中的意义!

肝细胞癌(HCC)在男性中的发病率较高,这可能由于雄激素受体(AR)与HCC的发病机制有关。然而,AR表达及其在HCC中的确切作用仍然存在争议。此前在HCC中进行的抗雄激素和抗AR的相关临床试验未能显示出其临床益处。近期,一项发表在Hepatology上的研究发现,在大约37%的HCC肿瘤的细胞核中存在AR的过表达,并且,其与晚期疾病阶段和患者的存活不良相关。在HCC细胞中,AR过度表达显着改变A
