摘要: 子宫内膜癌是女性生殖道常见的恶性肿瘤,在我国发病率仅次于宫颈癌,治疗方式包括手术治疗及辅助治疗(放疗、化疗和内分泌治疗等),通常应用于Ⅰb~Ⅳ期患者。然而,过度治疗和无效治疗会导致部分Ⅰ~Ⅱ期患者治疗后复发,并导致高级别(grade 3,G3)子宫内膜样腺癌(endometrial endometroid carcinoma,EEC)临床结局差异显著。分子特征评价可指导病理疑难型和罕见型子宫内膜癌患者精准治疗,多聚酶ε基因(POLE)突变型子宫内膜癌铂类化疗耐药性高,部分抗细胞毒性T淋巴细胞相关抗原4/细胞程序性死亡蛋白1(CTLA4/PD1)及磷脂酰肌醇3激酶/有丝分裂原活化蛋白激酶(PI3K/MEK)治疗有效;错配修复基因表达缺陷型子宫内膜癌常规放化疗耐药性高,部分抗细胞程序性死亡蛋白配体1/融合蛋白(PD-L1/B7-H4)治疗有效;高拷贝数变异型子宫内膜癌PI3K及周期蛋白依赖性激酶(CDK)抑制剂联合应用效果较好,还可考虑降低区域扩增基因表达水平相关靶向治疗;低拷贝数变异型子宫内膜癌鼠双微体蛋白4(MDM4)抑制剂治疗可能有效。通过层次聚类分析发现预后相关基因与子宫内膜癌预后显著相关,检测其表达水平可与分子分型相结合预测患者预后。现就美国癌症基因组计划(The Cancer Genome Atlas,TCGA)分子分型与本课题组发现的预后相关基因在子宫内膜癌精准辅助治疗中的临床意义作一总结。

Abstract: Endometrial carcinoma is a common malignant tumor in female genital tract. The incidence of endometrial carcinoma is second only to cervical cancer in China. The treatment methods include surgical treatment and adjuvant therapy (radiotherapy, chemotherapy, endocrine therapy), which are usually used in patients with stageⅠb ~ Ⅳ. However, overtreatment and ineffective treatment may lead to recurrence in some patients with stage Ⅰ to Ⅱ, and lead to significant differences in clinical outcomes of endometrial endometroid carcinoma (EECs) with high grade (grade 3, G3). The evaluation of molecular characteristics can be used to guide the accurate treatment of endometrial carcinoma with pathological difficulties and rare types. The resistance to platinum chemotherapy in endometrial carcinoma with polymerase ε gene (POLE) mutation is high. Anti-cytotoxic T lymphocyte antigen 4/programmed death protein 1 (CTLA4/PD1) antibody and phosphatidylinositol kinase 3/mitogen activator inhibitor (PI3K/MEK) were effective for POLE. Mismatch repair gene expression deficient endometrial carcinoma is highly resistant to conventional radiotherapy and chemotherapy. Anti-cell programmed death protein ligand 1/fusion protein (PD-L1/B7-H4) antibody is effective in the treatment of microsatellite instability. The combination of PI3K and cyclin dependent kinase (CDK) inhibitors could be used to reduce the level of regional  gene expression in copy number high group. Double microbody protein 4 (MDM4) inhibitors may be effective in the treatment of copy number low group. By hierarchical cluster analysis, some prognostic genes were found to be significantly correlated with the prognosis, and the expression level of these genes could be combined with molecular typing to predict the prognosis of endometrial carcinoma. We will summarize the clinical significance of TCGA molecular typing and the prognostic genes found by our team in precise adjuvant therapy of endometrial carcinoma.
