目的

分析非小细胞肺癌(nonsmall-cell lung cancer, NSCLC)表皮生长因子受体(epidermal growth factor receptor, EGFR)突变亚型的临床病理和预后意义。

方法

选择2016 年1 月至2022 年6 月我院收治的接受EGFR 基因检测127 例突变型晚期NSCLC 患者。 采用直接测序法进行EGFR 突变检测,根据突变位点分为四组:外显子(E)18 突变组、E19 突变组、E20 突变组、E21 突变组。 根据突变模式将E19 缺失突变分为三种亚型组:密码子缺失(codon deletion, CD)组、密码子替换和跳变(codon substitutions and skipping, CSS)组、CD 或CSS 加单核苷酸变异(single nucleotide variants, SNV)(CD/CSS+SNV)组。 主要观察指标为无进展生存期(progression-free survival, PFS)和总生存期(overall survival,OS)。

结果

EGFR 突变中,常见E19 缺失73 例(57.48%),其次为E21 突变40 例(31.50%),E18 突变6 例(4.72%),E20 突变8 例(6.30%)。 患者中位随访时间为22.23 个月(3.02~60 个月)。 E19 突变患者的中位PFS 和中位OS 时间最长(13 个月、30.59 个月),长于E18 突变(9 个月、10.85 个月)、E20 突变(10 个月、19.48 个月)和E21 突变(10 个月、16.92 个月)(P<0.05)。 多因素分析模型中,E19 突变是NSCLC 患者PFS 和OS 的影响因素(P<0.05)。 E19 突变患者中,CD/CSS+SNV 组中位PFS 和中位OS(43 个月、51.25 个月)长于CD 组(12 个月、29.87 个月)和CSS 组(10 个月、20.66 个月)(P<0.05)。 CD/CSS+SNV 组缺失碱基和缺失氨基酸数(12.80±2.88 个、4.40±0.91 个)低于CD 组(14.87±0.88 个、4.98±0.33个)和CSS 组(16.73±3.35 个、5.81±0.98 个)(P<0.05)。

结论

与E18/20/21 突变患者相比,E19 缺失突变患者PFS 和OS 预后好,提示E19 缺失是EGFR 突变型NSCLC 患者PFS 和OS 的预测因子。 E19突变患者中CD/CSS SNV 与PFS 和OS 长显著相关。

Objective

To investigate the prognostic value of plasma circulating tumor DNA (EGFR)in epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) in patients with advanced nonsmall cell lung cancer (NSCLC).

Methods

This study reviewed 127 patients with mutant advanced NSCLC who underwent EGFR gene testing in our hospital between January 2016 and June 2022. EGFR mutation was detected by direct sequencing method and divided into four groups according to mutation sites: exon (E) 18 mutant group, E19 mutant group, E20 mutant group, and E21 mutant group. In addition, E19 deletion mutations were divided into three subtype groups based on mutation patterns: codon deletion (CD), codon substitution and skipping (CSS), and CD or CSS plus single nucleotide variant (SNV) (CD/CSS+SNV). The main outcome measures were progression-free survival (PFS) and overall survival (OS).

Results

Among EGFR mutations, E19 deletion was the most common73cases (57.48%), followed by E21 mutation 40cases(31.50%), E18 mutation 6cases(4.72%), and E20 mutation 8 cases (6.30%). The median follow-up time for all NSCLC patients was 22.23 months (range 3.02 to 60 months). Patients with E19 mutation had the longest median PFS and OS duration (13 months,30.59 months), and were significantly longer than those with E18 mutation (9 months, 10.85 months), E20 mutation (10 months, 19.48 months), and E21 mutation (10 months, 16.92 months) (P<0.05). In the multivariate analysis model, E19 mutation was an independent influencing factor for PFS and OS in NSCLC patients (P<0.05). Among patients with E19 mutations, the median PFS and median OS (43 months, 51.25 months) in the CD/CSS+SNV group were significantly longer than those in the CD group (12 months, 29.87 months) and CSS group (10 months, 20.66 months) (P<0.05). The number of missing bases and missing amino acids in CD/CSS+SNV group (12.80±2.88, 4.40±0.91) were significantly lower than those in CD group (14.87±0.88, 4.98±0.33) and CSS group (16.73±3.35, 5.81±0.98) (P<0.05).

Conclusion

Compared with patients with E18/20/21 mutations, patients with E19 deletion mutations have a better prognosis for PFS and OS, suggesting that E19 deletion is a predictor of a better prognosis for PFS and OS in patients with EGFR mutant NSCLC. In addition, CD/CSS SNV was significantly associated with longer PFS and OS in patients with E19 mutations.
