UK Early Detection Initiative for Pancreatic Cancer
Pancreatic ductal adenocarcinoma (PDAC) is the most lethal common cancer (five-year survival is 5-7%). For ~80% of patients, PDAC is detected after disease spread, limiting treatment options. At the time of diagnosis, ~65% of PDAC patients have diabetes mellitus (DM). In ~15% of cases, DM is longstanding, however for >50% of PDAC patients DM is new–onset, with the DM diagnosis coming, on average, 13 months prior to PDAC being identified. Thus, new-onset DM (NOD) is an early warning sign of the presence of PDAC, and individuals with NOD are the largest high-risk group for PDAC. Approximately 1% of adults diagnosed with type 2 DM (T2DM) actually have PDAC-associated DM, a form of type3c DM (T3cDM). The scientific/medical community currently cannot distinguish PDAC-associated DM from T2DM and individuals with NOD are not screened. The US Consortium of Chronic Pancreatitis, Diabetes and Pancreatic Cancer is launching a collection of individuals with NOD. Similar initiatives in Europe are underway. Additional contributions are required; a UK component of the international NOD cohort will ensure that future biomarker-driven screening is relevant to the UK population/healthcare system, and will increase national awareness of the link between NOD and PDAC.
With programme funding from Cancer Research UK, the aim of our work at Liverpool is to develop a diagnostic test for use in individuals newly diagnosed with DM which will identify those most at risk of a diagnosis of PDAC, allowing them to be screened.
Individuals >50 years, newly diagnosed with DM are being recruited (target 2,500) from UK hospitals and general practice. Biosamples and questionnaire/clinical data are being collected to GCP and standardised to US and European collections. While recruitment is ongoing, further biomarker development for the high-risk NOD group is being undertaken. The specificity of biomarkers with potential to distinguish T3cDM (which harbours PDAC-associated DM) from T2DM will be tested in existing high-risk cohorts, including a pilot-scale collection of individuals with NOD (PANDIA) and the European Registry of Hereditary Pancreatitis and Familial Pancreatic Cancer (EUROPAC). Protocols for biomarker discovery using NOD will be developed/refined. The sensitivity/specificity for the detection of PDAC by combined biomarker and epidemiological/clinical feature analysis will be evaluated in the international NOD cohort. The cost-effectiveness of diagnosing PDAC earlier will be assessed. UK-NOD samples will be made available for research on early PDAC detection.
It is anticipated that our work will enable stratification of individuals with new-onset DM for PDAC risk, making it feasible in future to screen for PDAC in individuals with new-onset DM.
Validating candidate biomarkers for future use in pancreatic cancer detection amongst individuals with new-onset diabetes
Pancreatic cancer (PC) is set to become the second biggest cancer killer by 2030. Five year survival is less than five percent, largely due to late diagnosis.
At the time of PC diagnosis, half of PC patients have diabetes. PC-associated diabetes (called type 3C) can occur up to 3 years prior to PC diagnosis, however, it is mistaken for type 2 diabetes, and general practitioners miss this vital early warning sign of PC.
Approximately 1% of individuals diagnosed with type 2 DM have PC-associated diabetes, making new-onset diabetes the largest high-risk group for PC. Screening all new cases of type 2 diabetes (>250,000/year UK) would be prohibitively costly and mis-diagnosis would lead to dreadful consequences (major surgery/pancreas removal for cancer-free individuals).
In work funded by North West Cancer Research, we aim is to develop a blood test by which PC-associated DM can be distinguished from type 2 DM, allowing earlier PC diagnosis. We have analysed blood from PC patients and controls, and have identified proteins that distinguish PC-associated DM from long-standing type 2 DM. We established the UK’s first collection of individuals with new-onset diabetes, and now seek to test the specificity of our markers for PC-associated diabetes versus new-onset type 2 DM. We will also test markers in additional high-risk groups, where diabetes is monitored.
The accuracy of candidate markers, particularly their ability to give a negative result in cancer-free individuals will be established, paving the way for future testing in larger cohorts of individuals with new-onset diabetes and eventual screening of individuals with new-onset DM for PC.
Preclinical evaluation of Nrf2 inhibition as a means to improve chemotherapeutic efficacy in patients with pancreatic cancer
Pancreatic cancer is a devastating disease, usually causing death within one year of diagnosis. One of the reasons for this terribly poor prognosis is the failure of tumours to respond to chemotherapy. It is estimated that as few as 10% of patients respond to currently used treatments, such as gemcitabine.
The reasons for resistance of pancreatic cancer tumours to treatment are many-fold and our group is currently investigating how the levels of proteins involved in the drug uptake and metabolism relate to outcome for patients in randomised controlled clinical trials. However, an important source of drug resistance, which has received limited attention in pancreatic cancer, is the ability of cancer cells to protect themselves from chemical stress induced by chemotherapeutic drugs. A key protein orchestrating this cellular defence against chemotherapeutic drugs is Nrf2.
During inflammation or when our normal cells are exposed to environmental chemicals which cause the overproduction of highly damaging chemicals (such as, reactive oxygen species), the levels of Nrf2 are raised and induce the expression of genes involved in detoxification, thus protecting ourselves from chemical damage. The majority of pancreatic cancer cells have high Nrf2 and/or respond to chemotherapy by raising Nrf2 levels. In this way, Nrf2 protects pancreatic cancer cells from chemotherapy.
In work funded by Pancreatic Cancer Research Fund, we are currently undertaking preclinical analysis of the interplay between the Nrf2 pathway and the response to chemotherapy in pancreatic cancer. We will document the activation of Nrf2 in response to gemcitabine in cultured human pancreatic cancer cells and using sophisticated clinically relevant mouse models of oxidative stress and pancreatic cancer. Crucially, we will examine how best to inhibit Nrf2, such as to increase the cellular response to gemcitabine.
Our work will pave the way for combining Nrf2 inhibitors and chemotherapy in pancreatic cancer patients for the improved management of this disease.
