- Gastric cancer patients enrolled in this study must meet all of the following criteria:
- Male or female, aged ≥18 and ≤95 years.
- Histopathologically confirmed gastric cancer, as defined by the 2024 edition of the Chinese Society of Clinical Oncology (CSCO) Guidelines for the Diagnosis and Treatment of Gastric Cancer.
- No prior anti-tumor treatment (including radiotherapy, chemotherapy, targeted therapy, or immunotherapy).

About this study
This study focuses on the discovery of protein biomarkers for the early diagnosis of gastric cancer and the development of corresponding detection methods. By employing advanced mass spectrometry-based proteomic technologies, the investigators conducted an in-depth analysis of a large cohort of clinical samples to identify specific protein biomarkers capable of accurately distinguishing gastric cancer patients from healthy individuals. The findings from this research are expected to facilitate the development of novel non-invasive or minimally invasive diagnostic approaches, thereby improving early detection, enhancing patient prognosis, and increasing survival rates.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Gastric cancer | Patients with histopathologically confirmed gastric cancer | |
| Non Gastric Cancer | Healthy controls or patients with histologically confirmed precancerous gastric lesions that have not yet progressed to malignancy. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Diagnostic Performance of the Serum Protein Biomarker-Based Model for Gastric Cancer
Evaluation of the sensitivity and specificity of a diagnostic model constructed using key serum protein biomarkers for the early detection of gastric cancer.
Measured: 3 years
Secondary outcomes (3)
Predictive performance of the serum protein model for the progression risk from precancerous gastric lesions to gastric cancer
Predictive performance of the serum protein model for the progression risk from precancerous gastric lesions to gastric cancer, evaluated by prediction accuracy and area under the ROC curve (AUC).
Measured: 3 years
Predictive performance of the serum protein model for response to neoadjuvant therapy in gastric cancer
Predictive performance of the serum protein model for response to neoadjuvant therapy in gastric cancer, assessed by prediction accuracy and AUC.
Measured: 3 years
Prognostic performance of the serum protein model in gastric cancer patients
Prognostic performance of the serum protein model in gastric cancer patients, measured by prediction accuracy and AUC.
Measured: 3 years
