Minimally Invasive Detection of Lymphatic Micrometastases in Pancreatic Cancer (Sonoma)

April 1, 2022 updated by: Mayo Clinic
The major goal of this project is to reduce unnecessary pancreatic resections, namely resection in those patients with non-regional lymph node metastatses that cannot be cured with surgical resection. By combined minimally invasive methods for non-surgical biopsy and highly sensitive molecular assays for cancer cells, we believe we can increase the ability to detect distant lymph node metastases prior to surgical resection, and direct those patients for more appropriate therapy (including possible neo-adjuvant chemotherapy with or without surgery). We hypothesize that the combination of EUS-FNA and polymerase chain reaction (PCR) of a multimarker panel will increase the sensitivity for malignant lymph nodes compared with EUS-FNA cytology in patients with pancreatic ductal adenocarcinoma.
