Overview

In recent years, advances in protein post-translational modification (PTM) research have revealed histone succinylation as a novel epigenetic modification mechanism critically involved in tumor initiation, progression, and prognosis. Succinylation alters protein physicochemical properties and functions, thereby modulating cellular metabolism, proliferation, and apoptosis. Aberrant histone succinylation in tumor cells demonstrates significant correlations with tumor type, staging, and clinical outcomes, offering new avenues for early cancer diagnosis. This project utilizes blood serum samples to quantify histone succinylation levels through modification-specific antibody-based detection. Integrated with clinical data, this approach enables early, rapid, and accurate pan-cancer diagnosis, achieving tumor screening via a single-tube blood test. It represents a paradigm shift in precision oncology from "gene-driven" to "epigenetic-metabolic-driven" early detection.

Primary Objective To evaluate differential expression of serum histone succinylation between malignant solid tumor patients and healthy controls, thereby validating its early detection value. Secondary Objectives To determine correlations between serum histone succinylation levels and: Tumor types Tumor stages To statistically analyze associations of serum histone succinylation with: Therapeutic efficacy (surgical intervention, radiotherapy, systemic therapy) Clinicopathological variables

Outcomes

Primary Outcomes

Evaluate the positive rate of serum histone succinylation in patients with malignant solid tumors

Evaluate the positive rate of serum histone succinylation in malignant solid tumor patients versus healthy individuals through Western blot analysis, quantify the percentage difference between the two groups, and thereby validate its potential for early cancer screening

Time frame: 2025.08.01-2026.12.31

Secondary Outcomes

Define the relationship between histone succinylation modifications in serum and different tumor types as well as tumor staging

Analyze the relationship between histone succinylation modifications in serum and therapeutic efficacy (specifically surgery, radiotherapy, and systemic therapy)。
