Vaccine Therapy Combined With Adjuvant Chemoradiotherapy in Treating Patients With Resected Stage I or Stage II Adenocarcinoma (Cancer) of the Pancreas

RATIONALE: Vaccines made from gene-modified pancreatic cancer cells may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy, such as fluorouracil, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Giving vaccine therapy together with chemotherapy and radiation therapy after surgery may kill any remaining tumor cells.

PURPOSE: This phase II trial is studying how well giving vaccine therapy together with adjuvant chemoradiotherapy works in treating patients with resected stage I or stage II adenocarcinoma (cancer) of the pancreas.

Machine Learning for Recurrence Risk of Pancreatic Cancer After Radical Resection

Recurrence of Pancreatic Cancer(PCa) is a multifactorial event. Based on the clinicopathological characteristics and imaging data of patients with PCa, the investigators used image processing and machine learning algorithms to build a more comprehensive and robust model, and added some unused features to explore its clinical application value.

A retrospective analysis of patients with PCa who underwent radical resection at Zhejiang Cancer Hospital (Hangzhou, China) from January 2013 to December 2020. The database was extracted from the preoperative demographics, blood markers, and surgical pathology information of patients undergoing radical PCa surgery in the investigators' hospital. The investigators used the PyRadiomics platform to extract image features.

Early Detection Initiative for Pancreatic Cancer

The Early Detection Initiative for Pancreatic Cancer is a multi-center prospective study to determine if algorithm-based screening in patients with glycemically defined new onset hyperglycemia and diabetes has the potential for earlier detection of pancreatic ductal adenocarcinoma.

A Pilot Study to Assess Changes in Tumor Biology Following Second-line Treatment With Pembrolizumab Plus Lenvatinib in Patients With Advanced Pancreatic Ductal Adenocarcinoma

This is a clinical research study to learn if pembrolizumab in combination with lenvatinib can help to control pancreatic ductal adenocarcinoma.

Sorafenib, Pemetrexed, and Cisplatin in Treating Patients With Advanced Solid Tumors

RATIONALE: Sorafenib and pemetrexed may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Sorafenib may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with pemetrexed and cisplatin may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of sorafenib when given together with pemetrexed and cisplatin in treating patients with advanced solid tumors.

Study of Sotorasib Combined With Chemotherapy for Second Line Treatment of Pancreas Cancer

This is a multicenter, non-randomized, open-label, phase Ib/II study to evaluate the safety, tolerability and efficacy of sotorasib in combination with chemotherapy for patients with advanced KRAS p.G12C mutant pancreatic cancer with progression of disease after first line treatment. There will be a safety lead in to determine the safety and tolerability of the sotorasib in combination with standard chemotherapy. A Simon two-stage design will be employed to evaluate the efficacy of sotorasib in combination with standard of care second line chemotherapy.

Improving Pancreas Radiotherapy Plans Using Respiration-driven Anatomic Deformation: A Pilot Study

The overall aim of this study is to investigate a novel &#x0022dual instance&#x0022 planning method to make use of the respiratory motion to improve pancreatic radiation therapy (RT) treatment planning.

Specific Aim 1: Acquire patient abdominal MRI and CT at both deep inspiration (INSP) and expiration (EXP) positions and characterize the changes in geometric relationships between the INSP and EXP instances for tumor and normal tissues including stomach, duodenum and bowel. We hypothesize that INSP and EXP MRI and CT characterization will allow identification of patients who may benefit from the dual instance planning method.

Specific Aim 2: Develop, investigate and evaluate plans based on free breathing, single instance breath hold, and the novel dual instance anatomical information. We hypothesize that use of the dual instance method will lead to improved plans, demonstrated by the ability to increase dose to the target, while maintaining the clinically-accepted normal tissue dose constraints.

A Phase II Randomized Study of Gemcitabine and Nab-paclitaxel in Combination With S- 1/LV (GASL) or Oxaliplatin (GAP) as First-line Treatment for Metastatic Pancreatic Cancer

Gemcitabine and nab-paclitaxel are one standard of care for metastatic pancreatic adenocarcinoma (mPDAC) but the progression free survival (PFS) of the regimen is only 5.5 months. Previous phase II study showed gemcitabine and nab-paclitaxel plus cisplatin had a PFS of 10.1 months in mPDAC. This study will evaluate the efficacy and safety of gemcitabine, nab-paclitaxel plus S-1/LV (GASL) against gemcitabine, nab-paclitaxel plus oxaliplatin (GAP) in patients with mPDAC.

PANCREATIC DISEASE COHORT A Registry and Biospecimen Bank to Better Understand Pancreatic Disease

The specific aims of this project are to create a registry, as well as a biospecimen bank for individuals with pancreatic disease (e.g. pancreatic adenocarcinoma, pancreatitis, intraductal papillary mucinous neoplasm (IPMN) mucinous cystic neoplasm (MCN), and pancreatic intraepithelial neoplasia (PanIN) or have been determined to be at high-risk for pancreatic cancer. Biospecimen can be defined as blood, urine, tissue, stool, or saliva samples. Therefore, no hypothesis is to be tested. The personal data derived from the registry, correlated with biological information derived from the biospecimens will allow for future investigative studies of pancreatic cancer etiology and tumor biology. The long-term goals of the study are to advance the knowledge of the etiology and epidemiology of pancreatic cancer. It is anticipated that the knowledge derived will ultimately lead to improvements in the diagnosis, prevention, detection,and treatment of pancreatic cancer.

Pilot Project for Cardiopulmonary and Functional Evaluation in Patients With Pancreatic Cancer Associated Cachexia

Cachexia is a systemic catabolic syndrome with apparent effect on skeletal muscles, tolerance to chemotherapy, early toxicity and quality of life; however, its effect on cardiopulmonary function is not well understood. Preclinical studies demonstrated diaphragmatic muscle wasting(29) and left ventricular wasting and fibrosis associated with mouse cachexia models.(40) Many patients, who experience cancer cachexia, describe a generalized debility and a sense of breathlessness(41) despite adequate oxygenation in the peripheral blood as measured by pulse oximetry. Whether this is related to deconditioning associated with chemotherapy or related to direct effect on cardiac and diaphragmatic muscles remains unknown. In this pilot study, the investigators propose to perform a preliminary evaluation of the cardiopulmonary function in patients with pancreatic cancer, who are likely to develop cachexia, to assess for the feasibility of performing a larger prospective study to understand the impact of cancer cachexia on cardiopulmonary function. This pilot study will provide the foundation to potentially identify cachexia in early stages (pre-cachexia) to develop pharmacological or exercise based interventions to prevent or delay its progression. Based on clinical experience and published literature, it is expected that 60-70% of patients will have >10% weight loss during the course of this disease. More commonly, this is associated with clinical or radiographic disease progression, but certainly it can happen throughout the course of the disease even without disease progression.
