摘要:
目的 分析胆囊肉瘤样癌(GBSC)的临床病理特征、诊疗方法及预后。 方法 回顾性分析2015年1月—2023年4月郑州大学第一附属医院收治的16例胆囊肉瘤样癌患者的临床资料,包括患者的一般资料、临床表现、影像学特点、病理学特点和治疗方式等,并进行随访。采用Kaplan-Meier法进行生存分析,并绘制生存曲线,Log-rank检验比较组间差异。 结果 16例患者中男6例,女10例,年龄(62.9±8.4)岁。主要临床表现为右上腹痛13例(81.3%)、恶心5例(31.3%)、腹胀4例(25.0%)、纳差3例(18.8%)、乏力2例(12.5%)、发热2例(12.5%)、黄疸1例(6.3%),3例为无症状体检发现。其中81.3%(13/16)的患者初诊时处于疾病晚期(Ⅲ/Ⅳ期)。组织病理学表现:镜下观部分癌细胞呈梭形,核分裂像多见且异形性明显。免疫组化分析显示:Vimentin阳性表达率100%(16/16),AE1/AE3阳性表达率100%(16/16),CK8/18阳性表达率100%(16/16),81.3%(13/16)的患者Ki-67增殖指数高表达(≥50%),中位数为70%(范围:20%~90%)。16例患者均行手术治疗,根治性手术11例,姑息性手术5例,其中R0切除者9例,R1切除者2例,R2切除者5例,7例术后接受辅助治疗。16例患者均取得有效随访,随访0.5~26.0个月,中位随访时间11.0个月。至随访结束,2例患者存活,14例患者死亡,死亡原因均为肿瘤复发或转移,中位生存时间为10.0个月,术后1年、2年累积生存率分别为31.3%、8.3%。预后分析显示TNM分期(χ2=6.727,P=0.009)、手术方式(χ2=7.508,P=0.006)、切缘情况(χ2=7.934,P=0.005)、辅助治疗(χ2=4.608,P=0.032)与患者预后相关。 结论 胆囊肉瘤样癌的临床表现无特异性,确诊依赖免疫组化,大多数患者初诊时疾病处于晚期,总体预后较差,目前尚无针对性治疗方法,切缘阴性的根治性手术及辅助治疗可提高患者的生存率。 Abstract:Objective To investigate the clinicopathological features, diagnosis and treatment methods, and prognosis of gallbladder sarcomatoid carcinoma (GBSC). Methods A retrospective analysis was performed for the clinical data of 16 patients with GBSC who were admitted to The First Affiliated Hospital of Zhengzhou University from January 2015 to April 2023, including general information, clinical manifestations, imaging features, pathological features, and treatment modality, and follow-up was performed for all patients. The Kaplan-Meier method was used to perform the survival analysis and plot the survival curve, and the Log-rank test was used for comparison between groups. Results Among the 16 patients, there were 6 male patients and 10 female patients, with a mean age of 62.9±8.4 years. The main clinical manifestations were right upper abdominal pain in 13 patients (81.3%), nausea in 5 patients (31.3%), abdominal distension in 4 patients (25.0%), poor appetite in 3 patients (18.8%), weakness in 2 patients (12.5%), fever in 2 patients (12.5%), and jaundice in 1 patient (6.3%), and 3 patients were asymptomatic and were found to have this disease by physical examination. Of all patients, 81.3% (13/16) were in the advanced stage (stage Ⅲ/Ⅳ) at the time of initial diagnosis. Histopathological examination showed that some cancer cells were spindle-shaped under the microscope, with marked nuclear division and noticeable heteromorphism. Immunohistochemistry showed a positive expression rate of 100% (16/16) for Vimentin, AE1/AE3, and CK8/18, and Ki-67 proliferation index was highly expressed in 81.3% (13/16) of the patients (≥50%), with a median of 70% (range 20% — 90%). All 16 patients underwent surgical treatment, with radical surgery in 11 patients and palliative surgery in 5 patients, among whom 9 received R0 resection, 2 received R1 resection, and 5 received R2 resection, and 7 patients received adjuvant therapy after surgery. Effective follow-up was achieved for all 16 patients, with a follow-up time of 0.5 — 26.0 months and a median follow-up time of 11.0 months. By the end of follow-up, 2 patients survived and 14 patients died due to tumor recurrence or metastasis, with a median survival time of 10.0 months, and the 1- and 2-year cumulative survival rates after surgery were 31.3% and 8.3%, respectively. The prognostic analysis showed that TNM stage (χ2=6.727, P=0.009), surgical approach (χ2=7.508, P=0.006), margin condition (χ2=7.934, P=0.005), and adjuvant therapy (χ2=4.608, P=0.032) were associated with the prognosis of patients. Conclusion The clinical manifestations of GBSC lack specificity, and a confirmed diagnosis relies on immunohistochemical analysis. Most patients are in the advanced disease at the time of initial diagnosis and tend to have a poor prognosis. There are currently no targeted therapies for this disease, and radical surgery with negative margins and adjuvant therapy can improve the survival rate of patients. -
