Study Description

Brief Summary:

This study focuses on three different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract and pancreatic masses.

On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses and Lymph nodes are less developed.

The study therefore comprises two sub-studies, one on the pancreatic cysts, and another on pancreatic masses and lymph nodes.

1. Cysts The primary hypothesis of the study is that using nCLE in addition to EUS-FNA and tissue sampling allows better characterization of pancreatic cysts and improves appropriate therapeutic decision-making.

   For physicians, integrating nCLE into the diagnostic algorithm of pancreatic cysts could impact patient management by :

   • Ruling out malignancy for patients with benign appearing nCLE images.
   • Characterizing more malignant tumors in the pancreas.
2. Pancreatic masses and Lymph nodes The primary hypothesis of the study is that in vivo imaging of lymph-nodes near the gastrointestinal tract and pancreatic masses during EUS-FNA procedures is feasible and that descriptive criteria can be defined to further differentiate the different types of lesions.

Condition or disease	Intervention/treatment	Phase
Pancreatic Cyst; Pancreatic Neoplasms; Pancreatic Adenoma; Pancreatic Cancer; Pancreatic Islet Cell Tumors; Lymph Node; Lymphadenopathy	Procedure: EUS-FNA; Device: nCLE	Not Applicable

Detailed Description:

1. Medical background Pancreatic cancer is the fourth leading cause of cancer-related death in the United States. This disease is associated with a high mortality rate: the 5-year survival rate is estimated to be 4%. This is mainly due to the fact that the disease is often discovered at an already advanced disease state, which carries a dismal prognosis.

   1.1. Pancreatic Cysts

   Pancreatic cysts are quite rare, but are being increasingly recognized due to the expanding use of cross-sectional imaging. They are classified into three main classes:

   • Pseudocysts
   • Serous cysts : either serous cystic neoplasms (SCN) or Solid pseudo-papillary neoplasm (SPN)
   • Mucinous cystic neoplasms : either Intraductal Papillary Mucinous Neoplasm (IPMN) or mucinous cystadenomas/mucinous cystadenocarcinoma(MCN) Mucinous cystic neoplasms are considered to be malignant or pre-malignant and are considered for surgical resection, whereas pseudocysts and serous cysts are considered benign and with a low potential for malignancy. Pseudocysts and serous cysts are usually only considered for surgical resection when symptomatic or enlarging.

   1.2. Pancreatic masses Pancreatic solid masses can be either exocrine or endocrine tumors, or metastatic.Exocrine tumors are by far the most common type of pancreas cancer. Most of them are malignant. About 96% of cancers of the exocrine pancreas are adenocarcinomas, which is the most aggressive form of pancreas cancer.Endocrine tumors are uncommon. They represent 4% of pancreas tumors. They are known as neuroendocrine tumors (NETs), or islet cell tumors. These tumors can be benign or malignant.

   1.3. Lymph nodes Lymph nodes are examined in a patient with a suspicion of, or confirmed, cancer, as part of the staging. They may be either normal, inflammatory, or malignant.

2. Clinical background

   2.1. EUSFNA Endoscopic Ultrasound (EUS) is the diagnostic method of choice when a pancreatic lesion is found incidentally on cross-sectional imaging. Endoscopic UltraSound-guided Fine Needle Aspiration (EUS FNA) (respectively Endobronchial Ultrasound-guided Fine Needle Aspiration (EBUS FNA)) are procedures where a target tissue in proximity to the GI tract (respectively the pulmonary tract) is biopsied using a fine needle guided in real time by an ultrasound probe fixed at the tip of an endoscope.It may therefore be applied to pancreatic lesions, or lymph nodes examination.

   2.2. nCLE The principle of needle-based Confocal Laser Endomicroscopy (nCLE) is to image organs within or adjacent to the GI or respiratory tracts with a miniprobe inserted through an endoscopic needle. The fundamental technology as well as the principle of operation of nCLE are substantially similar to pCLE.

3. Clinical evidence More than 100 patients have already underwent an nCLE procedure, in the past studies. A first feasibility study enabled to define the final type of probe which would fit into a EUSFNA needle, and the INSPECT study enabled to define interpretation criteria on the micro-structure of pancreatic cysts. Less data is available on pancreatic masses and lymph nodes, except for a few images done in the first feasibility study.

4. Objectives

   4.1. Cysts 4.1.1. The primary objective of the study is to assess the diagnostic performance of the Cellvizio nCLE system in diagnosing pancreatic cysts, when associated with other diagnostic information.

   4.1.2. The secondary objectives are to assess the potential impact of the Cellvizio nCLE system on patient management and validate the interpretation classification criteria that were created during the previous INSPECT study on cysts.

   4.2. Pancreatic masses and Lymph nodes 4.2.1. The primary objective of the study is to define criteria of nCLE sequences in lymph nodes and pancreatic masses.

   4.2.2. The secondary objectives are to evaluate feasibility and safety of the Cellvizio nCLE during EUS-FNA procedures, build an atlas of images of nCLE sequences of pancreatic masses and lymph nodes, and, finally, retrospectively assess the diagnostic performance of nCLE in the diagnosis of pancreatic masses and lymph nodes, when associated with other diagnostic information
