这的药物化治疗及药物选择听到《J Cardiothorac Surg》在 2022 Dec 19;17(1):324.发表了一篇题目为《Osimertinib showed efficacy on contralateral multiple ground-glass nodules after segmentectomy for lung adenocarcinoma harboring primary EGFR-T790M mutation: a case report and review of the literature》肿瘤靶向药物治疗基因检测临床研究文章。该研究由Haijun Dong, Jianbin Zhang, Weiwei Min, Qibin Shen等完成。促进了肿瘤的正确治疗与个性化用药的发展,进一步强调了基因信息检测与分析的重要性。这项研究报告了一个多发磨玻璃样结节(mGGNs)合并原发EGFR T790M突变肺腺癌的病例,其对肿瘤诊断和治疗有以下几点启示: 对于mGGNs的鉴别诊断具有参考价值,提醒需要与原发多发肺癌进行鉴别,结合病理和分子检测进行确认。 对EGFR T790M突变阳性的肺腺癌患者,手术切除可能是贼佳治疗选择。 对于残余mGGNs,可以继续采用Osimertinib等EGFR-TKI目标治疗。 不同病灶对EGFR-TKI治疗反应存在异质性,提示存在克隆进化或耐药机制。 EGFR-TKI可作为mGGNs术后残余病灶的有效治疗手段,但需要进一步优化治疗策略。 该研究支持对肺癌进行基因检测指导正确用药的重要性,EGFR状态预测EGFR-TKI疗效。 总之,该研究通过一个典型病例阐明了EGFR突变阳性肺癌正确诊治策略,也提出了mGGNs个体化治疗的参考方案,对这类患者的临床管理具有一定的指导意义。

肿瘤治疗检测基因临床应用结果
靶向药物研究立项的依据:肺部多发磨玻璃结节(mGGNs)已被定义为同时性多原发性肺癌(SMPLC),SMPLC与肺内转移瘤的鉴别难度很大,其治疗仍存在争议。病例介绍:我们报道一例mGGNs与原发性EGFR-T790M突变肺腺癌同时发生,患者行左上肺病灶治好性切除,右肺各叶残留mGGNs继续奥希替尼治疗。这些 mGGNs 对奥希替尼表现出不同的反应。药物指导及病因判断的依据:我们报告了 mGGNs 术后治疗的成功策略。对于无法有效切除的,则进行了化疗、放疗、立体定向放疗、免疫治疗和靶向治疗。 EGFR-TKI治疗策略显示出显着优势,但如何达到更好的治疗效果还需要更多研究。关键词:表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI);多发磨玻璃结节 (mGGNs);同步多原发性肺癌 (SMPLC)。
肿瘤发生与革命国际数据库描述:
Background: Multiple ground-glass nodules (mGGNs) in the lung has been defined as synchronous multiple primary lung cancer (SMPLC), it is has been very difficult challenging to differentiate SMPLC from intrapulmonary metastases, and its treatment remains controversial.Case presentation: We report a case simultaneously involving mGGNs and lung adenocarcinoma harboring primary EGFR-T790M mutation, in which the patient underwent the radical resection of lesions in the left upper lung, and continued the osimertinib treatment for the residual mGGNs in all lobes of the right lung. These mGGNs displayed different responses to osimertinib.Conclusions: We reported a successful strategy on the postoperative treatment for mGGNs. For those that cannot be completely resected, the chemotherapy, radiotherapy, stereotactic body radiation therapy, immunotherapy and targeted therapy have been performed instead. The EGFR-TKI therapy strategy showed significant advantages, but how to achieve even better therapeutic effect needs more researches.Keywords: Epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI); Multiple ground-glass nodules (mGGNs); Synchronous multiple primary lung cancer (SMPLC).
