【摘要】:目的:研究梅奧分期中分層因素在HCCA患者預后中的作用,評價梅奧分期對預后的預測價值。梅奧分期和AJCC的TNM分期系統(tǒng)(第七版)對肝門膽管癌患者生存期的預測價值進行對比研究。方法:收集青島大學附屬醫(yī)院在2004-02-01至2013-01-01期間治療的可進行梅奧分期的335例肝門膽管癌患者的臨床資料。所有病例隨訪至2016年9月30日。根據(jù)患者的各種臨床資料,通過入選標準,對收入本研究的病例進行核對,符合排除標準的予以排除,最終確認研究對象。根據(jù)基線資料的定義,收集需要的臨床數(shù)據(jù)。用于梅奧分期的資料主要通過影像學資料獲得,而TNM分期的資料主要是根據(jù)手術病理結果獲得。采用Kaplan-Meier生存曲線和log-rank檢驗的方法對各個指標進行單因素分析,得到有統(tǒng)計學意義的影響因素。然后將上述影響因素導入Cox回歸分析,建立Cox風險比例模型,得到有統(tǒng)計學意義的與預后有關的獨立因素。使用Kaplan-Meier生存曲線和log-rank檢驗分別對兩種分期系統(tǒng)與生存期的關系進行相關性分析,并進行系統(tǒng)內(nèi)部的兩兩對比,評估分期系統(tǒng)內(nèi)部的區(qū)分度和整體的單一趨勢。使用ROC曲線對兩種分期系統(tǒng)進行單一趨勢性分析,通過其面積,比較其在HCCA患者預后中的評估能力。結果:至2016年9月30日,共283例患者死亡,40例無隨訪資料或拒絕參加此研究,12例患者刪失,刪失比例4.1%。中位生存期為12.4個月,1年、2年、3年生存率分別為(51.9±2.9)%,(21.1±2.5)%、(12.6±1.9)%。單因素分析中,認為腫瘤最大直徑3cm(P0.001)、白蛋白≥35g/L(P0.001)、腫瘤轉移(P0.001)、淋巴結轉移(P0.001)、治療方式(P0.001)、前白蛋白≥200g/L(P=0.015)、ECOG評分(P0.001)、Bismuth-Corlete分型(P0.001)、CA19-9≥1000U/ml(P=0.003)、血管受累(P=0.037)對HCCA的預后有影響。通過COX回歸分析,發(fā)現(xiàn)腫瘤最大直徑3cm(P=0.046)、Bismuth-Corlete分型(P0.001)、腫瘤轉移(P=0.004)、治療方式(P0.001)、白蛋白≥35g/L(P0.001)、ECOG評分(0.001)為預后的獨立危險因素。根據(jù)Kaplan-Meier生存曲線變化和log-rank檢驗結果,顯示兩種分期系統(tǒng)均和患者生存期相關(P0.001),分期級別越晚,預后情況越差。通過分期內(nèi)部的兩兩對比,發(fā)現(xiàn)梅奧分期內(nèi)部各分期之間異質性很好,優(yōu)于TNM分期。對兩種系統(tǒng)的預后評估能力進行單一趨勢性分析,發(fā)現(xiàn)梅奧分期ROC曲線下的面積最大(AUC=0.587),優(yōu)于TNM分期(AUC=0.501)。結論:基于單中心小樣本研究,梅奧分期可用于術前患者預后評估,預測價值優(yōu)于TNM分期,可以提供較好的分層能力。梅奧分期中的腫瘤轉移、腫瘤最大直徑3cm和ECOG評分是影響預后的獨立因素,而CA19-9≥1000U/ml是否可以作為3期的評估指標,需要進一步的研究。根治性手術切除和提高患者術前白蛋白水平,可明顯提高患者預后的生存期。
[Abstract]:Objective: to study the role of stratified factors in Mayo staging in the prognosis of HCCA patients. To evaluate the prognostic value of Mayo staging and AJCC TNM staging system (version 7th) in predicting the survival of patients with hilar cholangiocarcinoma. Clinical data of 335 patients with hilar cholangiocarcinoma treated for Mayo staging up to 2013-01-01. All cases were followed up until September 30th 2016. Through the inclusion criteria, the cases included in this study were checked, excluded according to the exclusion criteria, and the study object was finally confirmed. According to the definition of baseline data, Collect the necessary clinical data. The data used for Mayo's staging are obtained primarily through imaging data, The data of TNM staging were obtained mainly according to the results of operation and pathology. Kaplan-Meier survival curve and log-rank test were used to analyze the single factor of each index. The influencing factors were obtained, and the Cox risk ratio model was established by introducing the above factors into the Cox regression analysis. Kaplan-Meier survival curve and log-rank test were used to analyze the relationship between the two staging systems and survival time respectively, and the internal comparison was made. To evaluate the degree of differentiation within the staging system and the overall single trend. The ROC curve was used to analyze the single trend of the two staging systems, and their area was used to compare their ability to evaluate the prognosis of patients with HCCA. Results: by September 30th 2016, The median survival time was 12.4 months, 1 year, 2 years and 3 years survival rates were 51.9 鹵2.9%, 21.1 鹵2.5% and 12.6 鹵1.9%, respectively. It is considered that the maximum diameter of tumor is 3cm / L P0.001U, albumin 鈮,
