Diagnostic Test: EUS-guided portal vein and hepatic vein aspiration
EUS-guided portal vein and hepatic vein aspiration |
- Variant allelic fraction (expressed in %) of serum ctDNA from HVB, PVB and peripheral blood [ Time Frame: 3 months ]Plasma DNA will be extracted using the QIAamp Circulating Nucleic Acid Kit (Qiagen), and the concentration of the circulating tumor DNA will be reported in variant allelic fraction (expressed in %)
- Variant allelic fraction (expressed in %) of Genomic and proteomic analysis of ctDNA [ Time Frame: 3 months ]If ctDNA is identified, further genomic and proteomic analysis will be performed. It will be measured in terms variant allelic fraction (expressed in %)
- Staging of the GI cancer [ Time Frame: 3 months ]The pathological TNM staging of the resected specimen will be recorded.
- Recurrence [ Time Frame: 5 years ]any recurrence of the tumor will be recorded
- Overall survival [ Time Frame: 5 years ]overall survival will be recorded
- Progression-free survival [ Time Frame: 5 years ]progression free survival will be recorded
- Technical success rate of EUS-PVA and HVA [ Time Frame: 1 day ]The technical success rate of the EUS guided procedure will be recorded. Reasons for failure of the cases will be recorded.
- Adverse events of EUS-PVA and HVA [ Time Frame: 30 days ]the adverse events of the EUS procedure will be recorded
