摘要:

目的 探讨肿瘤病灶体积与子宫体积比值(T/U)、病灶组织中Ki-67蛋白、p16蛋白表达与子宫内膜癌病理学特征及复发的关系。 方法 选取经黔东南州人民医院病理学检查证实的150例子宫内膜癌患者进行随访观察,其中有28例患者随访2年后出现复发,122例患者未出现复发,对比两组患者手术时T/U及病灶组织中Ki-67蛋白、p16蛋白表达差异,并按照不同病理学特征分别对比上述指标,并对比不同T/U、Ki-67蛋白、p16蛋白表达患者的无复发生存时间差异。 结果 复发组患者的T/U值、Ki-67蛋白阳性表达率均显著高于非复发组,p16蛋白阳性表达率显著低于非复发组,差异有统计学意义(P < 0.05);T/U ≥ 0.18的子宫内膜癌患者中Ⅲ期患者占比、组织学低分化患者占比均显著高于T/U < 0.18的子宫内膜癌患者,差异有统计学意义(P < 0.05);Ki-67蛋白阳性表达的子宫内膜癌患者中Ⅲ期患者占比、组织学低分化患者占比、发生淋巴结转移的患者占比均显著高于Ki-67蛋白阴性表达的子宫内膜癌患者,差异有统计学意义(P < 0.05);p16蛋白阳性表达的子宫内膜癌患者中Ⅲ期患者占比、组织学低分化患者占比、发生淋巴结转移的患者占比均显著低于p16蛋白阴性表达的子宫内膜癌患者,差异有统计学意义(P < 0.05)。T/U ≥ 0.18的子宫内膜癌患者术后2年无复发生存时间短于T/U < 0.18的患者(χ2 = 6.962,P = 0.008);Ki-67阳性表达的子宫内膜癌患者术后2年无复发生存时间短于Ki-67阴性表达的患者(χ2 = 4.815,P = 0.028);p16蛋白阳性表达的子宫内膜癌患者术后2年无复发生存时间长于p16蛋白阴性表达的患者(χ2 = 4.279,P = 0.039)。FIGO分期为Ⅲ期、发生淋巴结转移、肌层浸润深度≥ 1/2、T/U值≥ 0.18、Ki-67蛋白阳性表达是子宫内膜癌手术后复发的危险因素(P < 0.05);p16蛋白阳性表达是子宫内膜癌手术后复发的保护性因素(P < 0.05)。 结论 子宫内膜癌患者T/U、Ki-67蛋白和p16蛋白表达与肿瘤发生发展有一定的关系,可能会增大患者手术后复发的风险。

Abstract:

Objective To investigate the correlation between the ratio of lesion volume to uterine volume (T/U), the expression levels of Ki-67 and p16 proteins in lesion tissue, and the recurrence risk of endometrial cancer. Methods A total of 150 patients diagnosed with endometrial carcinoma through pathological examination at Qiandongnan Prefecture People's Hospital were enrolled for follow-up observation. Among them, 28 patients experienced recurrence after a 2-year follow-up period, while 122 patients remained recurrence-free. The expression differences of Ki-67 protein and p16 protein in T/U and lesion tissues during surgery were compared between the two groups. Furthermore, these indexes were analyzed based on different pathological features, and the variation in relapse-free survival time was assessed among patients with distinct T/U status as well as Ki-67 and p16 protein expressions. Results The T/U value and the positive expression rate of Ki-67 protein were significantly higher in the relapsed group compared to the non-relapsed group, while the positive expression rate of p16 protein was significantly lower in the relapsed group (P < 0.05). Additionally, patients with T/U ≥ 0.18 had a significantly higher proportion of stage Ⅲ patients and patients with low histological differentiation compared to those with T/U < 0.18 (P < 0.05). Furthermore, patients with positive expression of Ki-67 protein exhibited a significantly higher proportion of stage Ⅲ patients, patients with low histological differentiation, and lymph node metastasis compared to those with negative expression of Ki-67 protein (P < 0.05). The proportion of stage Ⅲ patients exhibiting positive p16 protein expression, low histological differentiation, and lymph node metastasis was significantly lower compared to those with negative p16 protein expression (P < 0.05). Patients with endometrial cancer having a T/U ≥ 0.18 experienced shorter recurrence-free survival time 2 years post-surgery in comparison to patients with T/U < 0.18 (χ2 = 6.962, P = 0.008). Patients displaying positive Ki-67 expression had a shorter recurrence-free survival time 2 years after surgery than those with negative Ki-67 expression (χ2 = 4.815, P = 0.028). The recurrence-free survival time 2 years after surgery for patients expressing p16 protein positively was longer than that for patients expressing it negatively (χ2 = 4.279, P = 0.039). The presence of FIGO stage Ⅲ, lymph node metastasis, depth of myographic invasion ≥1/2, T/U value ≥ 0.18, and positive expression of Ki-67 protein were identified as significant risk factors for postoperative recurrence in endometrial cancer (P < 0.05). Conversely, the positive expression of p16 protein was found to be a protective factor against recurrence in endometrial carcinoma following surgery (P < 0.05). Conclusion The expression of T/U, Ki-67 protein, and p16 protein in endometrial cancer patients is associated with tumor progression and may augment the risk of postoperative recurrence.
