摘要 目的观察SOX4和P53在卵巢浆液性乳头状癌中的表达,初步探讨其生物学行为及临床意义。方法应用免疫组化EnVision法检测SOX4和P53在60例卵巢浆液性乳头状癌(卵巢癌组)和10例卵巢浆液性乳头状瘤(对照组)中的表达,并分析它们之间的关系以及与肿瘤的临床分期、细胞分级和预后之间的关系。结果卵巢癌组中SOX4的表达显著低于对照组(P<0.01),而P53的表达则显著高于对照组(P<0.05),但两者在肿瘤不同临床分期和细胞分级间表达差异均无统计学意义(P>0.05)。卵巢癌组中SOX4与P53的表达存在负相关(rs=-0.28,P<0.05);P53的表达与肿瘤的细胞分级呈正相关(rs=0.29,P<0.05)。患者的中位生存时间为31.84个月,5年无瘤生存率为26.05%;患者的年龄、临床分期和术后化疗与预后存在明显相关(P<0.05);而P53、SOX4的表达和肿瘤的细胞分级与预后均未见明显相关(P>0.05)。结论 P53基因突变与卵巢浆液性乳头状癌的发生密切相关,与肿瘤的细胞分级明显相关;卵巢浆液性乳头状癌中SOX4的表达下调,与P53的高表达呈负相关,SOX4参与了P53基因突变通路的调控,为进一步研究卵巢浆液性乳头状癌的发生机制提供了新思路。
