尽管在包括日本在内的大多数国家,人乳头瘤病毒 (HPV) 16 是导致宫颈癌的原因,但在蒙古和缅甸人群中,宫颈癌与 HPV 类型的关系尚不清楚。我们检测了 40 名日本、32 名蒙古和 30 名缅甸宫颈癌患者的福尔马林固定和石蜡包埋宫颈组织中 HPV 的表达。我们使用抗 HPV16 和抗 HPV 1、6、11、16、18 和 31 混合物进行免疫组织化学,然后将其与 Ki-67 和 p63 的表达相关联。日本、蒙古和缅甸宫颈癌患者中分别有 72%、65% 和 50% 的 HPV 16 被检出,而 40 名患者中的 5 名 (13%)、32 名患者中的 8 名 (25%) 和 30 名 HPV 16 阴性癌症患者中的 7 名 (23%) 分别对鸡尾酒中包含的其他 HPV 类型呈阳性。在日本和蒙古样本中,HPV 16 阳性患者的 Ki-67 标记指数 (LI) 和 p63 LI 显着高于 HPV 16 阴性患者。 p63 表达与日本和蒙古的 III 期和 IV 期显着相关。这些发现表明 HPV 16 可能与细胞增殖活性和肿瘤进展有关,可能取决于宫颈癌中 p63 的表达。此外,用于区分 HPV 类型的免疫组织化学检测在临床上也可能对宫颈癌有用。
Although human papillomavirus (HPV) 16 is the cause of cervical cancer in most countries including Japan, the involvement of cervical cancer with HPV types in Mongolian and Myanmar populations is largely unknown. We examined the expression of HPV in formalin-fixed and paraffin-embedded cervical tissues from 40 Japanese, 32 Mongolian, and 30 Myanmar cervical cancer patients. We performed immunohistochemistry using anti-HPV16 and anti-HPV 1, 6, 11, 16, 18 and 31 cocktail and then correlated it with the expression of Ki-67 and p63. HPV 16 was detected in 72%, 65% and 50% of Japanese, Mongolian and Myanmar cervical cancer patients, respectively, whereas 5 (13%) of the 40 patients, 8 (25%) of the 32 patients and 7 (23%) of the 30 patients in HPV 16-negative cancers were positive for other HPV types included in the cocktail, respectively. Ki-67 labeling index (LI) as well as p63 LI was significantly higher in HPV 16-positive patients than in HPV 16-negative ones in the Japanese and Mongolian samples. p63 expression was significantly associated with stage III and IV in Japan and Mongolia. These findings suggest that HPV 16 may be associated with cell proliferative activity and tumor progression, possibly depending upon the expression of p63 in the cervical cancer. In addition, immunohistochemical detection for distinguishing the type of HPV may also be useful for cervical cancer in the clinical setting.
