Abstract

Background: Lung cancer is the malignant tumor with high incidence and mortality in China, and more than 30% of non-small cell lung cancer (NSCLC) patients are in the locally advanced stage at the first-time diagnosis. Currently, neoadjuvant epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) combined with radical surgery is effective in the treatment of unresectable stage III EGFR-mutated NSCLC (NSCLCm), and related studies are gradually increasing. But the feasibility of neoadjuvant EGFR-TKI combined with radical surgery for unresectable stage III EGFR-mutant lung squamous cell carcinoma (LUSQm) remains controversial.

Case description: This report presented a successful case of neoadjuvant target-therapy with aumolertinib, the third-generation EGFR-TKI, combined with radical surgery for a stage IIIA LUSQm female patient. After four cycles (28 days/cycle) of neoadjuvant target-therapy, the tumor had a partial response on imaging evaluation and pathological evaluation after surgery showed complete tumor response. The neoadjuvant target-therapy was well tolerated. All adverse events (AEs) that occurred during the treatment were grade I, including decreased platelets, impaired liver function, and diarrhea. The patient was instructed to continue taking Aumolertinib for 3 years after surgery. At the cut-off date of April 1, 2024, the patient had no recurrence after 20 months of treatment.

Conclusions: The result of patient treatment demonstrated the potential feasibility of neoadjuvant Aumolertinib monotherapy for locally advanced LUSQm. The report provides some support for neoadjuvant target-therapy for LUSQm.

表皮生长因子受体突变肺鳞癌的新辅助奥莫拉替尼单药治疗:病例报告。
背景肺癌是我国发病率和死亡率较高的恶性肿瘤,30%以上的非小细胞肺癌(NSCLC)患者初诊时已处于局部晚期。目前,新辅助表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)联合根治性手术治疗不可切除的Ⅲ期EGFR突变NSCLC(NSCLCm)效果显著,相关研究也逐渐增多。但新辅助EGFR-TKI联合根治性手术治疗不可切除的III期EGFR突变肺鳞状细胞癌(LUSQm)的可行性仍存在争议:本报告介绍了一例第三代表皮生长因子受体抑制剂(EGFR-TKI)奥莫乐替尼(aumolertinib)新辅助靶向治疗联合根治性手术治疗IIIA期LUSQm女性患者的成功案例。经过四个周期(28 天/周期)的新辅助靶向治疗后,肿瘤在影像学评估中出现部分反应,手术后的病理学评估显示肿瘤完全反应。新辅助靶向治疗的耐受性良好。治疗期间发生的所有不良反应(AEs)均为 I 级,包括血小板减少、肝功能受损和腹泻。患者被要求在术后继续服用奥美乐替尼3年。截至2024年4月1日,患者在治疗20个月后没有复发:患者的治疗结果证明了新辅助奥美替尼单药治疗局部晚期LUSQm的潜在可行性。该报告为LUSQm的新辅助靶向治疗提供了一定的支持。
