異時性結(jié)直腸癌肝轉(zhuǎn)移療效的真實世界研究及熱消融后早期復(fù)發(fā)的預(yù)測模型構(gòu)建摘要：背景：結(jié)直腸癌是世界上最常見的惡性腫瘤之一，肝轉(zhuǎn)移是結(jié)直腸癌最常見的轉(zhuǎn)移部位，而異時性結(jié)直腸癌肝轉(zhuǎn)移療效的真實世界研究及熱消融后早期復(fù)發(fā)的預(yù)測模型構(gòu)建尚未得到足夠研究和探討。目的：通過對100例異時性結(jié)直腸癌肝轉(zhuǎn)移患者在真實世界中的臨床資料進行分析，探究異時性結(jié)直腸癌肝轉(zhuǎn)移的治療效果以及熱消融后早期復(fù)發(fā)的預(yù)測模型構(gòu)建。方法：收集100例異時性結(jié)直腸癌肝轉(zhuǎn)移患者的臨床資料，包括臨床表現(xiàn)、手術(shù)方式、治療方案、生存時間、復(fù)發(fā)情況等信息，并進行統(tǒng)計學(xué)分析。結(jié)果：異時性結(jié)直腸癌肝轉(zhuǎn)移的治療效果受到多個因素的影響，包括腫瘤大小、轉(zhuǎn)移數(shù)量、手術(shù)方式、治療方案等。熱消融后早期復(fù)發(fā)的預(yù)測模型構(gòu)建需要考慮腫瘤大小、腫瘤數(shù)量、最大腫瘤影像學(xué)直徑、熱消融時間等因素。結(jié)論：異時性結(jié)直腸癌肝轉(zhuǎn)移的治療效果受到多個因素的影響，熱消融后早期復(fù)發(fā)的預(yù)測模型構(gòu)建需要綜合考慮多個因素，這需要得到更多的研究和探討。
