摘 要:目的分析恶性胸膜间皮瘤(MPM)患者临床特征及分子标志物与预后的关系,探讨影响MPM预后的因素。方法收集北京肿瘤医院1996年6月至2012年5月收治的79例经病理组织学或细胞学确诊的MPM患者的临床及病理资料,随访至死亡或2012年10月31日,主要观察终点为总生存期。采用SPSS16.0统计分析软件进行单因素分析,了解可能影响总生存期及预后的因素。采用免疫组织化学法定性检测腺苷酸合成酶(TS)的表达,荧光原位杂交法检测棘皮动物微管相关类蛋白4-肿瘤组织间变淋巴瘤激酶(EML4-ALK)基因重排,并分析其与含培美曲塞化疗方案疗效和生存期的关系。结果全组中位总生存期(MST)为15.5个月(95%CI为10.6-20.4)。与生存期显著相关的治疗因素包括接受手术、全身化疗、化疗方案中是否含培美曲塞及是否接受二线或以上方案治疗等,各组MST为:接受手术的患者为5.4个月(95%CI为3.6-7.3),低于未手术者的17.7个月(95%CI为11.8-23.5,P=0.030);接受全身化疗的患者为18.0个月(95%CI为12.3-23.8),长于未接受该方案者的7.9个月(95%CI为1.1-14.7,P=0.001);接受含培美曲塞方案化疗的患者为21.9个月(95%CI为14.1-29.7),长于未接受该方案者的8.8个月(95%CI为4.2-13.4,P=0.000);曾接受二线及以上化疗方案的患者为21.0个月(95%CI为12.7-29.3),长于未曾接受此治疗者的12.1个月(95%CI为6.4-17.8,P=0.022)。42例患者曾用含培美曲塞方案化疗,客观缓解率为33%(14/42),疾病控制率为79%(33/42),中位无病进展生存期(PFS)为4.8个月(95%CI为3.6-6.0),MST为21.9个月(95%CI为14.1-29.7)。29例患者中TS表达阳性6例;32例中EML4-ALK基因重排阳性6例。Ts表达与培美曲塞为基础化疗方案的PFS显著相关(P=0.0Objective To identify potential prognosis related clinical and molecular factors in malignant pleural mesothelioma ( MPM ). Methods Seventy-nine patients with MPM treated in Beijing Cancer Hospital from June 1996 to May 2012 were enrolled in this study. Clinical and pathological data were collected, including age, gender, smoking status, treatment, response, and molecular biomarkers such as thymidylate synthetase (TS) expression, echinoderm microtubule-associated protein-like 4-anaplasticlymphoma kinase (EML4-ALK) gene rearrangement. The primary endpoint was overall survival (OS). SPSS 16. 0 statistical analysis software was used for univariate analysis. The expression of TS was detected by immunohistochemistry (IHC). Fluorescence in situ hybridization (FISH) was performed to detect EML4- ALK gene rearrangement. Efficacy of the chemotherapy regimen including pemetrexed was analyzed with these molecular biomarkers. Results The median survival time (MST) of all patients was 15.5 months (95%CI: 10. 6 -20. 4). Univariate survival analysis revealed that treatment factors including receiving operation, systemic chemotherapy, pemetrexed-based chemotherapy and capability of receiving second ( or above) line chemotherapy were significantly related with OS. The MST of patients receiving operation was 5.4 months ( 95 % CI: 3.6 - 7.3 ) , significantly shorter than the 17.7 months ( 95 % CI: 11.8 - 23.5 ) in those who didn' t receive operation ( P = 0. 030). Patients receiving systemic chemotherapy had a longer MST of 18.0 months (95% C1:12. 3 -23.8 ) as compared to the 7.9 months (95% CI:I. 1 - 14. 7 ) in those who didn' t (P = 0. 001 ). The MST of pemetrexed-based chemotherapy was 21.9 months (95% CI: 14. 1 - 29. 7) compared with 8.8 months (95% CI:4. 2 - 13.4) of regimens without pemetrexed (P =0. 000). For patients capable of receiving second (or above ) line chemotherapy the MST was longer (21.0 months, 95% CI: 12. 7- 29.3�
