To assess the efficacy of radical surgery combined with recombinant adenoviral human p53 (rAd-p53) gene therapy in treatment of resectable non-small cell lung cancer.
A total of 163 patients with resectable NSCLC meeting the inclusion criteria were randomly assigned to two groups: radical surgery alone (S) and radical surgery plus surgical wound surface injection of 2 x 10 rAd-p53 units (SP). All patients were followed up for at least 3 years for efficacy and safety. Study endpoints were loco-regional recurrence or distant metastasis (Rec-Met) rate as primary endpoints, and progression free survival (PFS), overall survival (OS) and safety assessments as secondary endpoints.
Recurrence or metastasis (Rec/Met) after surgery were 24/82 (29.27%) in SP group and 37/81 (45.68%) in S group. The difference in the Rec/Met rate was statistically significant (p = 0.0304) by chi-square test. The hazard ratios after adjusting of age and disease stage (S vs. SP) of PFS and OS are 1.772 (95% CI, 1.102 to 2.848) and 2.047 (95% CI, 1.109 to 3.377), respectively. The 3 years PFS and OS for SP vs. S were 71.9% vs. 46.9%, and 88.4% vs. 67.0%, respectively. Differences in PFS and OS between two treatment groups were significant with the p values of 0.0165 and 0.0191, respectively, using Log-Rank test.
The wound surface injection of rAd-p53 showed efficacious effects in preventing recurrence or metastasis and improving PFS and OS after a radical surgery in patients with NSCLC.
评估根治性手术联合重组人p53腺病毒(rAd-p53)基因治疗可切除非小细胞肺癌的疗效。
163例符合纳入标准的可切除非小细胞肺癌患者随机分为两组:单纯根治性手术组(S组)和根治性手术加手术创面注射2×10个rAd-p53单位组(SP组)。所有患者均随访至少3年,评估疗效和安全性。研究终点以局部区域复发或远处转移(Rec-Met)率为主要终点,无进展生存期(PFS)、总生存期(OS)和安全性评估为次要终点。
SP组术后复发或转移(Rec/Met)为24/82(29.27%),S组为37/81(45.68%)。经卡方检验,Rec/Met率差异有统计学意义(p = 0.0304)。调整年龄和疾病分期后(S组 vs. SP组),PFS和OS的风险比分别为1.772(95%CI,1.102至2.848)和2.047(95%CI,1.109至3.377)。SP组与S组的3年PFS分别为71.9%和46.9%,3年OS分别为88.4%和67.0%。采用Log-Rank检验,两个治疗组之间的PFS和OS差异均有统计学意义,p值分别为0.0165和0.0191。
rAd-p53创面注射对NSCLC患者根治性手术后预防复发或转移、改善PFS和OS有显著效果。
