Abstract

High-risk human papillomaviruses (HPVs) are considered risk factors in the origin of several human malignancies, such as breast, cervical, head and neck, as well as colorectal cancers. However, there are no data reported on the HPV status in colorectal cancer in the State of Qatar. Therefore, we herein examined the presence of high-risk HPVs (16, 18, 31, 33, 35, 45, 51, 52, and 59), using polymerase chain reaction (PCR) in a cohort of 100 Qatari colorectal cancer patients, and their association with tumor phenotype. We found that high-risk HPV types 16, 18, 31, 35, 45, 51, 52, and 59 were present in 4, 36, 14, 5, 14, 6, 41, and 17% of our samples, respectively. Overall, 69 (69%) of the 100 samples were HPV positive; among these, 34/100 (34%) were positive for single HPV subtypes, while 35/100 (35%) of the samples were positive for two or more HPV subtypes. No significant association was noted between the presence of HPV and tumor grade, stage, or location. However, the presence of coinfection of HPV subtypes strongly correlated with advanced stage (stage 3 and 4) colorectal cancer, indicating that the copresence of more than one HPV subtype can significantly worsen the prognosis of colorectal cancer. The results from this study imply that coinfection with high-risk HPV subtypes is associated with the development of colorectal cancer in the Qatari population.

摘要

高危型人乳头瘤病毒(HPV)被认为是多种人类恶性肿瘤发病的危险因素,如乳腺癌、宫颈癌、头颈癌以及结直肠癌。然而,卡塔尔国尚无关于结直肠癌患者HPV感染状况的报道。因此,我们采用聚合酶链反应(PCR)检测了100例卡塔尔结直肠癌患者队列中高危型HPV(16、18、31、33、35、45、51、52和59型)的存在情况及其与肿瘤表型的关系。我们发现,高危型HPV 16、18、31、35、45、51、52和59型在我们的样本中所占比例分别为4%、36%、14%、5%、14%、6%、41%和17%。总体而言,100个样本中有69个(69%)HPV呈阳性;其中,34/100(34%)为单一HPV亚型阳性,而35/100(35%)的样本为两种或更多HPV亚型阳性。HPV感染与肿瘤分级、分期或位置之间未发现显著关联。然而,HPV亚型合并感染与晚期(3期和4期)结直肠癌密切相关,这表明多种HPV亚型共存可显著恶化结直肠癌的预后。本研究结果表明,高危型HPV亚型合并感染与卡塔尔人群结直肠癌的发生有关。
