[Abstract]Objective To evaluate the value of combined detection of antigen 199 (CA199), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA) and alpha fetoprotein (AFP) in the diagnosis of ovarian cancer, so as to provide reference for the diagnosis of ovarian cancer, and to intervene as early as possible and promote the prognosis of patients. Methods Selected patients with ovarian cancer and benign ovarian tumors admitted to our hospital from August 2018 to October 2019, 80 cases each were selected as observation group 1 and observation group 2. In addition, 80 healthy subjects in the same period were selected as the control group. After review and approval by the hospital ethics committee, the participants informed and agreed to cooperate, the observation group 1, observation group 2 and the control group were all tested for CEA, CA125, CA199, and AFP, and the corresponding test results of the three groups were compared and combined the positive rate of tests and individual tests.

卵巢癌是女性常见恶性肿瘤疾病,临床中发现,近年来此类疾病患病率呈明显递增趋势[1]。卵巢癌发病率仅次于宫颈癌和子宫内膜癌,但其病死率在生殖系统恶性肿瘤中居首位。卵巢癌早期阶段患者无典型临床症状,且缺乏特异的早期筛查标志物,早期诊断困难,多数患者发现情况下已处在晚期阶段,甚至扩散到子宫、盆腔等器官,所以需尽早采取有效的诊断、治疗措施,从而提高患者的生存质量[2]。研究发现,血清肿瘤标志物变化先于影像学、临床症状,检测操作方便,患者耐受度高[3]。因此在临床中可用于肿瘤的鉴别诊断、临床分期、预后判断等,指导临床诊疗,改善患者预后,目前卵巢癌病理类型复杂,复发率高,预后差。诊断及临床分期判断时仍缺乏高灵敏度、高特异度的肿瘤标志物。虽然,类抗原CA125、CA199等是肿瘤组织的特殊抗原,是诊断卵巢癌的敏感标志物,但是单项检测漏诊率较高,所以为了提高诊断准确性,开始尝试联合检测手段,且检验阳性率较高[4]。基于此,本文就我院同期的卵巢癌、卵巢良性肿瘤患者以及健康体检者为例进行研究,分析CEA、CA125、CA199、AFP联合检测价值。 1 资料与方法 1.1 一般资料 研究对象选自2018年8月至2019年10月,获得医院伦理委员会批准,选取对象包括卵巢癌患者、卵巢良性肿瘤患者、健康体检者,各选取80例,分别作为观察1组、观察2组、对照组。纳入标准:①参与患者、家属知情同意。②基线资料完整,参与者具有配合能力。排除标准:①人类免疫缺陷病毒感染等疾病患者。②精神病史等丧失配合能力患者。③心、肝、脾、肾等内脏器官病变患者。 观察1组:年龄22~68岁,平均(47.50±5.60)岁;经病理确诊,卵巢浆液性囊腺癌35例,卵巢黏液囊腺癌25例,透明细胞癌以及子宫内膜样腺癌各10例。 观察2组:年龄23~66岁,平均(47.02±5.30)岁;经病理确诊,成熟性囊性畸胎瘤38例,黏液性囊腺瘤16例,浆液性囊腺瘤以及混合性囊腺瘤各13例。
