腫瘤治療檢測(cè)基因臨床應(yīng)用結(jié)果

使用分子靶向藥物實(shí)現(xiàn)更好的治療反應(yīng)和長(zhǎng)期預(yù)后的個(gè)性化醫(yī)療是肺癌治療的常見(jiàn)做法。然而，在找到合適的機(jī)構(gòu)進(jìn)行基因檢測(cè)及基因批量測(cè)試開(kāi)始為普能病人使情況下，藥物治療會(huì)繼續(xù)進(jìn)行，而不會(huì)檢測(cè)到罕見(jiàn)突變。佳學(xué)基因收集到一個(gè)腫瘤基因檢測(cè)報(bào)告的病例，該患者為男性年齡為 67 歲的男性，他被診斷患有腺癌 T1cN3M1a，IVA 期。 在7 年前使用 EGFR 突變基因檢測(cè)進(jìn)行的初步篩查和 ALK 免疫組化檢測(cè)均為陰性。盡管一線細(xì)胞毒性聯(lián)合化療非常有效，而且臨床觀察到原發(fā)病灶逐漸消退。但是在最近的支氣管鏡重新活檢后，通過(guò)基因組測(cè)試檢測(cè)到 RET 融合。此外，佳學(xué)基因檢測(cè)能夠從 7 年前的胸腔積液細(xì)胞塊獲得的 FFPE 標(biāo)本中確認(rèn) RET。隨后給予分子靶向藥物塞爾帕替尼(selpercatinib)，對(duì)原發(fā)灶和包括腦轉(zhuǎn)移在內(nèi)的所有轉(zhuǎn)移灶非常有效。腫瘤靶向藥的基因檢測(cè)描述了一個(gè) RET 融合陽(yáng)性肺癌病例，其中分子靶向治療和細(xì)胞毒性藥物顯示出強(qiáng)烈的反應(yīng)，并且長(zhǎng)期治療得到很好的維持。 7年未確診的RET融合突變?cè)俅位顧z標(biāo)本，二代測(cè)序能夠正確診斷。關(guān)鍵詞：RET融合肺癌；重新活檢病例報(bào)告檢測(cè)到RET突變；基因突變；重新活檢； selpercatinib。

腫瘤發(fā)生與革命國(guó)際數(shù)據(jù)庫(kù)描述：

Personalized medicine, utilizing molecular-targeted drugs to improve therapeutic response and long-term prognosis, has become standard in the treatment of lung cancer. However, in cases predating the availability of gene batch tests, medical treatment proceeded without detecting rare mutations. We present the case of a sixty-seven-year-old man diagnosed with adenocarcinoma T1cN3M1a, stage IVA. Initial screening conducted 7 years ago, using EGFR mutation and ALK immunohistochemical tests, yielded negative results. Although first-line cytotoxic combination chemotherapy proved remarkably effective, a gradual regression of the primary lesion was observed. Subsequent bronchoscopic re-biopsy identified RET fusion through gene panel testing. Additionally, RET was confirmed in FFPE specimens obtained from pleural effusion cell blocks collected 7 years ago. Administration of the molecular-targeted drug selpercatinib following the diagnosis displayed high efficacy in treating the primary lesion and all metastatic lesions, including brain metastases. We present a case of RET fusion-positive lung cancer, where molecular targeted therapy and cytotoxic drugs elicited a significant response, leading to long-term therapy maintenance. Next-generation sequencing accurately diagnosed the RET fusion mutation using the re-biopsy specimen, which had gone undiagnosed for 7 years. Keywords: RET fusion lung cancer; case report on RET mutation detected through re-biopsy; gene mutation; re-biopsy; selpercatinib.
