Cancer:胃肠道间质瘤病人或患其它癌症的风险较高

2015-05-05 佚名 生物谷

近日,来自加州大学圣地亚哥分校医学院的研究人员在杂志Cancer上刊登了其最新研究成果,他们首次进行了一项基于人口的调查,将胃肠道间质瘤(GIST)同其它癌症的发病风险相互联系了起来,研究结果表明,在5.8名GIST患者中就有1人在疾病诊断前或者诊断后患其它恶性肿瘤。 研究者表示,GIST患者更易于患其它肉瘤疾病、非霍奇金淋巴瘤、类癌瘤、黑色素瘤、结直肠癌、胰腺癌以及非小细胞肺癌等癌症;而仅

近日,来自加州大学圣地亚哥分校医学院的研究人员在杂志Cancer上刊登了其最新研究成果,他们首次进行了一项基于人口的调查,将胃肠道间质瘤(GIST)同其它癌症的发病风险相互联系了起来,研究结果表明,在5.8名GIST患者中就有1人在疾病诊断前或者诊断后患其它恶性肿瘤。

研究者表示,GIST患者更易于患其它肉瘤疾病、非霍奇金淋巴瘤、类癌瘤、黑色素瘤、结直肠癌胰腺癌以及非小细胞肺癌等癌症;而仅有5%的GIST患者存在遗传性障碍,促使其患多发性的良性或恶性肿瘤,本文研究表明,这些GIST患者患癌或许并不局限于上述症状,但具体的机制目前尚不清楚。

后期研究者将通过更多的研究来揭示GIST和其它癌症之间的关联,诊断为GIST的病人通常会进行基于其它癌症的额外筛查,而这些其它癌症往往是患者最易感的;研究者在美国人群中研究发现,患者在GIST诊断前癌症发生的流行率会增加44%,而在GIST诊断后患其它癌症的风险会增加66%,而患者最常见的肿瘤则为泌尿生殖道、乳腺、呼吸道及血液肿瘤等。

非西班牙裔病人在GIST诊断前患其它癌症的发病率较高,肿瘤尺寸小于10厘米的患者相比肿瘤尺寸较大的患者而言患第二种癌症的可能性较大;而肿瘤尺寸小于2厘米的患者患其它恶性肿瘤的可能性是最高的,而这与GIST诊断前后无关。
