The construction of Gene detection technology flow
At this stage, a small panel targeted high-throughput sequencing process for gastrointestinal stromal tumors was established, and the association of tumor-associated mutation profiles in different patients with clinical stage was initially explored.
It is planned to collect about 100 cases of gastrointestinal stromal tumors after surgery (freezing tissue or FFPE sections), DNA extraction and high-throughput sequencing of small panels, and analysis of the relationship between the mutation spectrum of each sample and the corresponding patient clinical data (staging).

Establishment of non-invasive gene testing technology process
In this stage, we plan to establish a small panel of peripheral blood cfDNA targeting high-throughput sequencing process, and verify the consistency of peripheral blood cfDNA and tissue gDNA in gene detection of gastrointestinal stromal tumors.
About 50 patients were planned to be enrolled.
Peripheral blood was collected once for each patient and the blood volume was 10mL.
Meanwhile, the tumor tissue samples were collected within 5mm in diameter, depending on the size of the lesion .
DNA extraction and small panel sequencing were performed for the two types of samples of the patients respectively, and the DNA sequencing results of the two types of samples were compared, and the clinical data of the corresponding patients were referenced to evaluate the consistency of the results of peripheral blood cfDNA and tissue gDNA for the gene detection of gastrointestinal stromal tumor.

DNA extraction and small panel sequencing were conducted for each patient sample.
Based on the indicator results of the previous mutant spectrum for each stage of gastrointestinal stromal tumor, the clinical stage classification of patients and the benign and malignant nodules were determined by the mutant spectrum, and compared with the real clinical data of patients

Prospective cohort (double-blind recommended)
Peripheral blood of about 150 patients was collected once and the blood volume was 10mL .
Meanwhile, the tumor tissue samples were collected within 5mm in diameter, depending on the size of the lesion.
Patients focus on the early stage of stromal tumors or those whose size under gastroenteroscopy is between 2 and 5 cm.
DNA extraction and small panel sequencing were conducted for each patient sample.
Based on the indicator results of the previous mutation spectrum for each stage of gastrointestinal stromal tumor, the clinical stage classification of patients and the benign and malignant nodules were determined by the mutation spectrum, and compared with the real clinical data of patients.
