近日,泛生子在2021年美國癌癥研究協(xié)會年會(AACR2021)發(fā)布了22項(xiàng)全新研究成果。

       近日,泛生子在2021年美國癌癥研究協(xié)會年會(AACR2021)發(fā)布了22項(xiàng)全新研究成果。企業(yè)運(yùn)用RNA融合檢測、新型MSI檢測生信算法模型、“一步法”等創(chuàng)新技術(shù),及Onco PanscanTM、肉瘤全體系基因檢測等核心產(chǎn)品,攜手13家國內(nèi)頂級醫(yī)院,圍繞中國人群深入分析肺癌、腸癌、胰 腺癌、神經(jīng)系統(tǒng)腫瘤、胸腺癌等多癌種遺傳、突變、融合特征分布,驗(yàn)證并挖掘多癌種免疫治療標(biāo)志物有效性,以及罕見案例和新型療法,進(jìn)而為癌癥精準(zhǔn)診療方式、診療產(chǎn)品設(shè)計等提供重要啟示(附研究列表)。

       泛生子首席醫(yī)療官胡云富博士表示:“作為基礎(chǔ)研究與臨床應(yīng)用的橋梁,泛生子始終致力于為二者建立良性互促關(guān)系,全力推動轉(zhuǎn)化醫(yī)學(xué)發(fā)展。本次研究成果,基于企業(yè)創(chuàng)新技術(shù)及產(chǎn)品,助力多癌種基因組學(xué)的特征分析及技術(shù)優(yōu)化路線探索,并為新產(chǎn)品設(shè)計提供思路。如在軟組織肉瘤領(lǐng)域,通過RNA融合檢測技術(shù),大幅提高融合檢出率,為更多肉瘤患者提供獲益可能;在遺傳性腫瘤領(lǐng)域,Li-Fraumeni綜合征篩查方法的提出也將提升該類患者檢出率,為其提供更多干預(yù)機(jī)會;在結(jié)直腸癌領(lǐng)域,KMT2C/2D失活突變的分析也將為免疫治療適用患者提供更多獲益可能。此外,罕見病例挖掘及其新型療法的嘗試,將推動該類型患者的診療研究進(jìn)一步發(fā)展。”

       探索技術(shù)優(yōu)化路線

       為打破DNA-seq針對檢測基因融合所存在的局限性,研究2288對常規(guī)技術(shù)進(jìn)行優(yōu)化,在RNA層面實(shí)現(xiàn)了更精準(zhǔn)、高效、低耗的融合基因突變檢測,在142人的軟組織肉瘤隊(duì)列中進(jìn)行評估及驗(yàn)證。研究顯示相比DNA單獨(dú)檢測,DNA+RNA綜合檢測對于軟組織肉瘤融合的檢出率提高了177%,可為更多肉瘤患者提供臨床獲益可能。

       研究2080對NGS MSI生信算法進(jìn)行了多重優(yōu)化,并與金標(biāo)準(zhǔn)PCR對比,在2523例泛癌種大樣本中進(jìn)行驗(yàn)證。結(jié)果表明,優(yōu)化后的算法與金標(biāo)準(zhǔn)PCR檢測方法一致性達(dá)99.9%。其中MSI-H陽性預(yù)測率PPV為98.73%,MSS陰性預(yù)測率NPV為99.92%。

       關(guān)注遺傳性腫瘤特征

       兩項(xiàng)研究(#1464、#2557)通過對胚系突變的深入分析,為Li-Fraumeni綜合征提供了篩查方法,探討了中國人群胰 腺癌患者遺傳特征及具體分布,為遺傳性腫瘤篩查及診療提供證據(jù)及思路。

       探索基因突變及融合特征

       九項(xiàng)研究(#2217、#2163、#2223、#2216、#2215、#2313、#2252、#2183、#2182)分別對軟組織肉瘤、黑色素瘤、神經(jīng)內(nèi)分泌腫瘤、非小細(xì)胞肺癌、胸腺癌、小腸腺癌、壺腹癌等多個癌種進(jìn)行突變、融合特征多維度探索,尋找潛在精準(zhǔn)治療靶點(diǎn)、耐藥靶點(diǎn)及有效應(yīng)對措施。

       挖掘免疫治療標(biāo)志物

       四項(xiàng)研究(#1639、#1640、#1641、#1681)分別探討了KMT2C/D失活突變、DDR信號通路相關(guān)基因變異、ARID1A突變以及BRCA1/2突變對泛癌種免疫治療療效的預(yù)測作用,為免疫治療提供啟示。

       關(guān)注罕見案例及新型療法

       五項(xiàng)研究(#0803、#0422、#1209、#1199、#0625)分別在林奇綜合征相關(guān)肺癌、轉(zhuǎn)移性黑色素瘤、間變性甲狀腺癌、甲狀腺乳頭狀癌以及脂肪肉瘤患者中檢測出特殊的分子異常。研究通過分子檢測輔助患者進(jìn)行診斷分型,為患者采用新型的靶向治療、免疫治療方案,最終使患者成功獲益。
