Lipoprotein a is an Independent Risk Factor for Overall Survival in Patients With Pancreatic Cancer: a Propensity Score Matching Analysis

March 12, 2024 updated by: jingxue

Background: This study aims to assess the prognostic significance of serum lipoprotein (a) [Lp (a)] levels on overall survival (OS) and progression free survival (PFS) in individuals diagnosed with pancreatic cancer through the utilization of propensity score matching (PSM).

Methods: A retrospective analysis was conducted on the clinicopathological data of 364 patients diagnosed with pancreatic cancer at the Affiliated Hospital of Qingdao University from January 2019 to December 2022. The cut-off value for Lp (a) was determined based on one-year survival rates after diagnosis. Patients were then categorized into the high and low Lp (a) groups. We applied PSM analysis to minimize selection bias. The study compared OS and PFS between two groups by Kaplan-Meier method and analyzed differences using the log-rank test. Additionally, univariate and multivariate Cox-regression analyses were performed to identify prognostic factors among patients.

Study Population

This research involved the inclusion of 364 individuals who were diagnosed with pancreatic cancer at the Affiliated Hospital of Qingdao University from January 2019 to December 2022, following pathological confirmation. The criteria for inclusion were as follows: (1) Adult patients aged over 18 years; (2) Patients with histologically confirmed pancreatic cancer through surgical or puncture procedures; (3) Complete lipid profiles available within one week prior to diagnosis. Exclusion criteria were as follows: (1) Presence of concurrent malignancies; (2) History of previous treatments such as pancreatectomy, chemotherapy, or radiation therapy; (3) Incomplete clinicopathological information.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
OS
Time Frame: 1-30months
The primary endpoint was overall survival (OS), defined as the time from pathological diagnosis to either death or the most recent follow-up.
1-30months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
PFS
Time Frame: 1-10months
The secondary measure was the duration from the initial diagnosis to disease progression, referred to as progression-free survival (PFS). Both are measured in months.
1-10months
