Elizabeth M. Jaffee, M.D., deputy director of the Sidney Kimmel Comprehensive Cancer Center and the associate director of the Bloomberg~Kimmel Institute for Cancer Immunotherapy, discussed what patients with pancreatic cancer need to know about immunotherapy and answered audience questions about clinical trials, COVID-19, and side effects, among other topics. There are a number of good centers. A key to unlocking pancreatic cancer immunotherapy may be treating early-stage pancreatic cancer, when peripancreatic inflammation promoted by the microbiome potentiates oncogenic signaling and suppresses innate and adaptive immunity. We don't know that being on immunotherapy helps, but it certainly doesn't hurt and make you more susceptible. What I can tell you is there a number of clinical trials that are ongoing looking at that right now. Several pancreatic cancer antigens have been identified that are shared by the majority of pancreatic tumors and include carcinoembryonic antigen (CEA), mucin‐1 (MUC‐1), and the product of mutated KRAS.23 All these antigens have the potential to be used as vaccines for pancreatic cancer. Chris Macdonald, head of research at Pancreatic Cancer UK said: "These findings are very encouraging and offer real hope that a new, innovative immunotherapy treatment for pancreatic cancer … There's a lot of work ongoing, a lot of studies. 190.5K views | +1 today. That's why it's taking a little bit longer. Dr. Elizabeth Jaffee: Yeah, that's a great question. If your immune system is otherwise functioning, if you're not on high doses of chemotherapy, if you haven't had a bone marrow transplant, if you're not immunocompromised where your immune system just can't function well, then you're like anyone else when it comes to COVID, you're susceptible to COVID, but not really any more so. *Immunotherapy results may vary from patient to patient. Arthur N. Brodsky, Ph.D. 2018 was a big year for cancer immunotherapy, with several approvals in new cancer types as well as a number of promising breakthroughs with the potential to dramatically improve how patients are treated in the future. The only time compassionate use really of benefit is if you have a drug, whether it's immunotherapy or non-immunotherapy, that's been shown to work in that patient population. What are some common side effects of immunotherapy that your patients have experienced? Another important difference is PD-L1. And are there any new early detection tests?". According to the American Cancer Society, the estimated number of new pancreatic . What I could tell you is that because it's so rare, it's not as easy to study. Genetically modified mouse models that develop spontaneous pancreatic tumors are an important model for studying the effects of the tumor microenvironment on response to immunotherapy. Pancreatic adenocarcinoma (PAC) is the seventh leading cause of cancer-related death in both sexes, causing more than 331,000 deaths per year globally .An estimation of … Challenge yourself in 2021 with our '21 Challenge to journal, get creative, correspond with friends, or anything else that brings joy and reflection. It should only be done in clinical trials, Brian Brewer: One of our patient audience members ... Well not a patient. And again, this is very important. Introduction. The aim of this review is to discuss the preclinical and clinical studies that have focused on different immuno-oncology approaches applied to pancreatic cancer, which we assign to the “dark side” of immunotherapy… The impact of immunotherapy on the survival of pancreatic adenocarcinoma patients who received definitive surgery of the pancreatic tumor: a retrospective analysis of the National Cancer Database. And so basically we need to make sure we can get the best quality that have the ability to come into that tumor and kill that tumor in order to have success with immunotherapy against pancreatic cancer. What we now know is that we can take just even a small piece of a tumor, pancreatic tumor, or any other kind of tumor, and within a week, we can sequence those tumors and find out what all the mutations are, or the proteins that make that cancer different from the normal tissue. A phase II clinical trial of gemcitabine with vismodegib, a Hedgehog antagonist used to deplete stroma, showed no survival benefit in pancreatic cancer patients.36 Subsequent studies have reported stroma depletion may actually enhance tumor growth underscoring the complex role that stroma plays in tumor biology.37 Despite the conflicting results of tumor response to stroma‐depleting therapies, the tumor microenvironment plays a significant role in tumor biology and in modulating the immune recognition of pancreatic cancer (Figure 1B). Therapeutic challenges and current immunomodulatory strategies in targeting the immunosuppressive pancreatic tumor microenvironment. So immunotherapy currently is able to help maybe 15 to 20% of all cancer patients with metastatic disease. And if it's due to the immunotherapy, we would treat it quickly. So these proteins or antigens that pancreatic cancers express come in different categories. Solid tumors such as pancreatic cancer, colon cancer, and breast cancer contain an average of 33 to 66 somatic mutations that result in altered protein production and, in turn, could lead to the expression of “foreign” antigens. And for pancreatic cancer, the one that we're testing most readily is mutated KRSA. Immunotherapy and pancreatic cancer There’s an urgent need for improved treatment options for pancreatic cancer. Most of the cancers that do respond to immunotherapy have very high numbers of mutations. There is also an FDA-approved immunotherapy drug, Keytruda®, for pancreatic cancer … Here, we review novel immunotherapy strategies currently under investigation to (1) confer antigen specificity, (2) enhance T cell effector function, and (3) neutralize immunosuppressive elements within the tumor microenvironment that may be rationally combined to untangle the web of immune resistance in PDA and other tumors. And so we're going to have to develop new agents, and some of them are already being tested in the clinics, in order to be able to make immunotherapy work well. Results from “COMBAT Trial” show pancreatic cancer patients can greatly benefit from immunotherapy. In this review we will briefly describe the limited success that has been seen with immune checkpoint blockade and pancreatic cancer vaccines and explore the unique tumor microenvironment of pancreatic cancer that acts to limit the effectiveness of immunotherapy. Targeting and modulating the tumor immune microenvironment could not only switch the immune system toward anti-cancer, but also may improve sensitivity toward established chemotherapy. Targeting the Tumor Microenvironment: An Unexplored Strategy for Mutant KRAS Tumors. A good point, a good outcome of telemedicine is that I can reach people all over the country. Pancreatic cancer tumors are composed of malignant cancer cells surrounded by an abundant desmoplastic stroma (Figure 1A). How has this changed your practice? Chris Macdonald, head of research at Pancreatic Cancer UK said: "These findings are very encouraging and offer real hope that a new, innovative immunotherapy treatment for pancreatic cancer … Use the link below to share a full-text version of this article with your friends and colleagues. Thank you so much, Dr. Jaffee. Oncolytic Viruses and Immune Checkpoint Inhibition: The Best of Both Worlds. Scientists often refer to pancreatic tumors as being … Patients with pancreatic cancer show poor response to checkpoint blockade with anti‐CTLA‐4 and anti‐PD1/anti‐PD‐L1 immunotherapies. Herein, we comprehensi vely reviewed the history and highlights of the interactions among pancreatic cancer, the gut microbiota and therapeutic efficacy and showed the promising future of manipulating the gut microbiota to improve clinical outcomes of pancreatic cancer. Dendritic cells and macrophages are the inflammatory cells that can either help the cancer grow or they can help bring in the T cells if they are taught to recognize the tumor. Theranostic Approach for Pancreatic Cancer. Learn more. Brian Brewer: Thanks so much Dr. Jaffee. They don't have a formalized program like PanCAN, but they can also help and refer you. Brian Brewer: I think this might be related, but we have a question coming in. Is there, is immunotherapy- Another question coming in. Dr. Elizabeth Jaffee: Yes, it's a great question. The aim of this review is to discuss the preclinical and clinical studies that have focused on different immuno-oncology approaches applied to pancreatic cancer, which we assign to the “dark side” of immunotherapy, in the sense that it represents one of the solid tumors showing less response to this type of therapeutic strategy. Patients who received the GVAX vaccine 2 weeks prior to surgical resection had an increased frequency of tumors positive for PD‐L1 (12.5% of resected tumors in the unvaccinated group vs 25% of resected tumors in the GVAX group), suggesting this as a likely mechanism of immune resistance.32 Building on these results, GVAX is currently being studied in a clinical trial with or without nivolumab for patients with resectable pancreatic cancer at Johns Hopkins University (NCT02451982; clinicaltrials.gov). The incidence of pancreatic cancer has been increasing while its 5-year survival rate has not changed in decades. I'd like to remind before we get going with the questions, we already have a bunch of rolling in as you're talking, which is exactly what we like to see, that if you haven't yet submitted a question or if you think of one as we talk, please feel free to submit those through the Q&A box. Murine models for familial pancreatic cancer: Histopathology, latency and drug sensitivity among cancers of Palb2, Brca1 and Brca2 mutant mouse strains. Simply select your manager software from the list below and click on download. Thus, pan‐depletion of FAP+ fibroblasts in humans is not a safe or feasible treatment approach. A key component of pancreatic cancer’s lethality is its acquired immune privilege, which is … And we've been developing vaccines targeting a few of those shared antigens. That means the cancer … So we have the shared antigens. So depending on where you live, you may want to contact one of those institutions, but I can tell you that we also will, you contact one institution and we'll all tell you about the best studies out there for you. And now you have to give immune modulating agents, such as anti-PD-1 and anti-CTLA-4, and also other agents that might target those pathways I was telling you about that define heterogeneity of the cancer. Treatment of tumor‐bearing mice with CSF1R blockade did result in enhanced effector T‐cell tumor infiltration and reduced tumor growth.
