Embodiment 1

[0089] Embodiment 1: sample collection and sample processing

[0090] (1) A total of 302 HCC patients who were unwilling or unable to undergo surgical resection in the First Affiliated Hospital of Zhengzhou University from June 2016 to May 2020 received DEB-TACE as initial treatment were included. Inclusion criteria were: 1) age > 18 years; 2) liver function Child-Pugh A or B grade; 3) Eastern Cooperative Oncology Group (ECOG) score 0-2 points; HCC that is willing or unresectable and has at least one measurable lesion; 5) has not received other treatments such as surgery, cTACE, ablation or targeted drugs; 6) DEB-TACE is the initial treatment. Exclusion criteria: 1) Child-Pugh C grade of liver function; 2) ECOG score 3-4 points; 3) invasion of hepatic vein or inferior vena cava; 4) complete obstruction of main portal vein; 5) suffering from other malignant tumors; 6) Incomplete clinical or follow-up data; 7) Severe heart, liver and kidney dysfunction, abnormal coagulation fun...

Embodiment 2

[0097] Example 2: Screening of independent factors associated with survival after DEB-TACE in patients with liver cancer

[0098] (1) Univariate Cox regression analysis was used to analyze the clinical factors that may be related to the survival of patients with liver cancer after DEB-TACE:

[0099] In the modeling group, SPSS 21.0 statistical software was used to conduct univariate Cox regression analysis on the clinical factors that may be related to the survival of patients with liver cancer after DEB-TACE, and to evaluate the prognostic value of clinical factors on the survival of patients with liver cancer after DEB-TACE . Through single factor Cox regression analysis, it was found that aspartate aminotransferase, glutamyl transpeptidase, alkaline phosphatase, alpha-fetoprotein expression, bilirubin, ascites, tumor diameter, tumor number, proportion of tumor to liver, presence or absence Tumor capsule, presence or absence of portal vein invasion, presence or absence of d...

Embodiment 3

[0110] Example 3: Establishment of a survival prediction model for patients with liver cancer after DEB-TACE

[0111] The independent prognostic factors related to the survival of patients with liver cancer after DEB-TACE obtained by multivariate Cox regression analysis were assigned, and the assigned values ​​are shown in Table 3.

[0112] Table 3 Assignment of independent prognostic factors related to survival after DEB-TACE in patients with liver cancer

[0113] variable assignment distant metastasis With distant metastasis = 1, without distant metastasis = 0 ALRI ≤40＝0，＞40＝1 Child-Pugh classification A=0, B=1 tumor diameter ≤5cm=0, >5cm=1 tumor to liver ratio ≤1 / 2＝0，＞1 / 2＝1 portal vein invasion no=0, yes=1 Alpha-fetoprotein expression ≤400ng / mL=0, >400ng / mL=1

[0114]According to the results of multivariate Cox regression analysis, the risk function expression of each factor was established with the β value of t...

Abstract

The invention belongs to the field of medical biotechnology, and specifically discloses a kit for predicting the prognosis of liver cancer treated with drug-loaded microsphere chemoembolization. Reagents and / or instruments for Pugh grade, proportion of tumor to liver, status of portal vein invasion, status of distant metastasis of tumor. The kit of the present invention can predict the survival period of liver cancer patients after DEB-TACE treatment according to the clinical indicators before DEB-TACE treatment of liver cancer patients, evaluate the prognosis of liver cancer patients with DEB-TACE treatment, and help interventional doctors to screen suitable DEB-TACE before operation. The patient population treated by TACE can also facilitate clinicians to accurately assess the prognosis of patients and formulate individualized follow-up plans based on expected survival.

Description

technical field [0001] The invention belongs to the technical field of medicine and biology, and in particular relates to a kit for predicting the prognosis of liver cancer treated with drug-loaded microsphere chemoembolization. Background technique [0002] According to the 2020 Global Cancer Statistics Report, primary liver cancer is one of the most common malignant tumors and has become the third leading cause of tumor-related death worldwide, among which hepatocellular carcinoma (HCC) is the most common pathological type. The onset of HCC is insidious, and most patients are already in the middle and advanced stages when they are diagnosed, losing the chance of radical surgery. For these patients, transarterial chemoembolization (TACE) is recognized as the most effective treatment. In recent years, due to the advantages of drug-eluting beads (DEB) that can be loaded with chemotherapeutic drugs and localized sustained and slow release in the tumor, drug-eluting beads chem...
