Abstract:Objective? To explore a genetic marker model that can accurately predict the patient's survival status and improve the success rate of prostate cancer treatment.Methods? Using gene expression profiling data and clinical data of prostate cancer patients, the genes with significant correlation with patient survival time were selected as features to construct a prognostic model, and the accuracy of model prediction was verified. Results? A prognostic marker model consisting of three molecular markers including ENSG00000101844, ENSG00000107077 and ENSG00000117461 was constructed. The prognostic marker model showed better predictive performance and could effectively improve the accuracy of prognosis evaluation of prostate cancer.Conclusion? The mRNA prognostic marker model can effectively predict the survival status of patients, and has high prediction accuracy, practicability and stability. It provides possibility for the application of molecular prognosis markers in actual clinical practice, and also selects patients. Provide a more accurate guidance on reasonable treatment options, and provide a theoretical basis for the development of medical device products for detecting the prognosis of prostate cancer.

目前,治療癌癥的方法雖然有很多種,但是不同癌癥療法在不同患者的實(shí)際治療中效果參差不齊。因此針對(duì)不同的患者應(yīng)選擇其適合的療法,而癌癥的預(yù)后判斷是癌癥患者進(jìn)行個(gè)體化治療的前提。在此背景下,預(yù)后標(biāo)記物的研究顯得尤為重要。前列腺癌已成為危害男性健康的主要惡性腫瘤之一,在歐美發(fā)達(dá)國(guó)家及地區(qū),其發(fā)病率已躍居至男性惡性腫瘤發(fā)病率的首位[1,2]。根據(jù)最新的10 年統(tǒng)計(jì)數(shù)據(jù),前列腺癌在大多數(shù)國(guó)家的發(fā)病率急劇上升,其中尤以亞洲、北歐和西歐地區(qū)的增長(zhǎng)最為快速[3]。我國(guó)前列腺癌的發(fā)病率目前雖然不高,但其趨勢(shì)卻不容樂(lè)觀,伴隨著我國(guó)社會(huì)經(jīng)濟(jì)的飛速發(fā)展,人們生活及飲食習(xí)慣的改變,人口老齡化日益加劇,前列腺癌的發(fā)病率也在不斷上升且增長(zhǎng)的速度更為快速,現(xiàn)已成為我國(guó)男性泌尿生殖系統(tǒng)中最常見(jiàn)的惡性腫瘤[4]。本文收集了前列腺癌患者的基因表達(dá)譜數(shù)據(jù)和樣本臨床數(shù)據(jù),篩選出與患者生存時(shí)間顯著相關(guān)的基因作為特征來(lái)構(gòu)建預(yù)后模型,最終構(gòu)建的以3個(gè)基因?yàn)榻M合的預(yù)后標(biāo)志物模型表現(xiàn)出較好的預(yù)測(cè)性能,提高了前列腺癌預(yù)后的準(zhǔn)確性。
