Adenocarcinoma, Circulating Tumor Cell, Ethmoid Sinus Tumor
Conditions
Brief summary
The role of this transversal study is to assess the specificity and sensitivity of liquid biopsy to detect circulating cells tumor of adenocarcinoma of the ethmoid. Blood sample of participants will be collected at the moment of the surgical procedure or recurrence diagnosis; immediately after surgery; at day 8-10; at month 2-3 of postoperative follow-up. Two comparison groups will be studied: one age and gender-matched group and one professional exposure-matched group to assess the sensitivity and specificity of liquid biopsy
Interventions
DIAGNOSTIC_TESTLiquid biopsy
For cases: 60 mL blood sample (40 ml for CellSave analysis and 20ml for collection) at visit1 then 20 ml for CellSave analysis at visit2 and visit3 For controls: 40 ml (20ml for CellSave analysis and 20ml for collection) at visit1
