The Florida pancreas collaborative next-generation biobank: Infrastructure to reduce disparities and improve survival for a diverse cohort of patients with pancreatic cancer

Background: Well-annotated, high-quality biorepositories provide a valuable platform to support translational research. However, most biorepositories have poor representation of minority groups, limiting the ability to address health disparities. Methods: We describe the establishment of the Florida Pancreas Collaborative (FPC), the first state-wide prospective cohort study and biorepository designed to address the higher burden of pancreatic cancer (PaCa) in African Americans (AA) compared to Non-Hispanic Whites (NHW) and Hispanic/Latinx (H/L). We provide an overview of stakeholders; study eligibility and design; recruitment strategies; standard operating procedures to collect, process, store, and transfer biospecimens, medical images, and data; our cloud-based data management platform; and progress regarding recruitment and biobanking. Results: The FPC consists of multidisciplinary teams from fifteen Florida medical institutions. From March 2019 through August 2020, 350 patients were assessed for eligibility, 323 met inclusion/exclusion criteria, and 305 (94%) enrolled, including 228 NHW, 30 AA, and 47 H/L, with 94%, 100%, and 94% participation rates, respectively. A high percentage of participants have donated blood (87%), pancreatic tumor tissue (41%), computed tomography scans (76%), and questionnaires (62%). Conclusions: This biorepository addresses a critical gap in PaCa research and has potential to advance translational studies intended to minimize disparities and reduce PaCa-related morbidity and mortality

The Role of Endoscopic Ultrasonography in the Diagnosis and Staging of Pancreatic Cancer

Pancreatic cancer is the fourth leading cause of cancer-related death and the second gastrointestinal cancer-related death in the United States. Early detection and accurate diagnosis and staging of pancreatic cancer are paramount in guiding treatment plans, as surgical resection can provide the only potential cure for this disease. The overall prognosis of pancreatic cancer is poor even in patients with resectable disease. The 5-year survival after surgical resection is ~10% in node-positive disease compared to ~30% in node-negative disease. The advancement of imaging studies and the multidisciplinary approach involving radiologists, gastroenterologists, advanced endoscopists, medical, radiation, and surgical oncologists have a major impact on the management of pancreatic cancer. Endoscopic ultrasonography is essential in the diagnosis by obtaining tissue (FNA or FNB) and in the loco-regional staging of the disease. The advancement in EUS techniques has made this modality a critical adjunct in the management process of pancreatic cancer. In this review article, we provide an overall description of the role of endoscopic ultrasonography in the diagnosis and staging of pancreatic cancer

Minimally Invasive Mediastinal Staging of Non–Small-Cell Lung Cancer: Emphasis on Ultrasonography-Guided Fine-Needle Aspiration

Background: Mediastinal staging in patients with non–small-cell lung cancer (NSCLC) is crucial in dictating surgical vs nonsurgical treatment. Cervical mediastinoscopy is the “gold standard” in mediastinal staging but is invasive and limited in assessing the posterior subcarinal, lower mediastinal, and hilar lymph nodes. Less invasive approaches to NSCLC staging have become more widely available. Methods: This article reviews several of these techniques, including noninvasive mediastinal staging of NSCLC, endobronchial ultrasound (EBUS) and fine-needle aspiration (FNA), endoscopic ultrasound (EUS) and FNA, and the combination of EBUS/EUS. Results: Noninvasive mediastinal staging with computed tomography and positron-emission tomography scans has significant false-negative and false-positive rates and requires lymph node tissue confirmation. FNA techniques, with guidance by EBUS and EUS, have become more widely available. The combination of EBUS-FNA and EUS-FNA of mediastinal lymph nodes can be a viable alternative to surgical mediastinal staging. Current barriers to the dissemination of these techniques include initial cost of equipment, lack of access to rapid on-site cytology, and the time required to obtain sufficient skills to duplicate published results. Conclusions: Within the last decade, these approaches to NSCLC staging have become more widely available. Continued study into these noninvasive techniques is warranted

An open-label, single-arm pilot study of EUS-guided brachytherapy with phosphorus-32 microparticles in combination with gemcitabine +/- nab-paclitaxel in unresectable locally advanced pancreatic cancer (OncoPaC-1): Technical details and study protocol.

Current treatment options for patients with unresectable locally advanced pancreatic cancer (LAPC) include chemotherapy alone or followed by chemoradiation or stereotactic body radiotherapy. However, the prognosis for these patients remains poor, with a median overall survival <12 months. Therefore, novel treatment options are needed. Currently, there is no brachytherapy device approved for pancreatic cancer treatment. Hereby, we present the protocol of a prospective, multicenter, interventional, open-label, single-arm pilot study (OncoPac-1, Clinicaltrial.gov-NCT03076216) aiming to determine the safety and efficacy of Phosphorus-32 when implanted directly into pancreatic tumors using EUS guidance, for patients with unresectable LAPC undergoing chemotherapy (gemcitabine ± nab-paclitaxel)
