The authors investigated whether immunoediting occurs in human cancers. Using PDAC samples from Short-Term and Long-Term survivors, the authors found that when the immune system recognises an immunogenic antigen (neoantigen) in a primary tumour, this induces the antigen to be subsequently eliminated in the recurrent tumour. Tumours evolve under a stronger immune pressure lose more immunogenic neoantigens, thus show less heterogeneity. The authors further propose that a fundamental function of the immune system is to maintain integrity of the host genome.

Intravital imaging technology guides FAK-mediated priming in pancreatic cancer precision medicine according to Merlin status

Sci Adv. 2021 Oct;7(40):eabh0363. doi: 10.1126/sciadv.abh0363.
The authors highlight the potential clinical benefits of utilising targeted short-term inhibition of focal adhesion kinase (FAK) in pancreatic ductal adenocarcinoma (PDAC), to pre-treat the environment around the tumour to increase chemosensitivity of the cancer. Transient FAK inhibition ‘priming’ resulted in reduction of PDAC metastatic spread and sensitised the cells to subsequent chemotherapy treatment. FAK inhibition priming was also found to render a subtype of pancreatic cancer patients with high FAK and low expression of the tumour suppressor Merlin, more responsive to chemotherapy.

The APGI contributed 175 genomes to the Pan-Cancer Project, a global effort that has created a resource of over 2600 cancer genome of 38 different tumour types. Researchers across the globe will use the database to study pancreatic and other cancers, bringing better diagnosis and treatments within reach.

Genetic counselling and personalised risk assessment in the Australian pancreatic cancer screening program

Hered Cancer Clin Pract. 2019 Oct 23;17:30. doi: 10.1186/s13053-019-0129-1.
Screening trial participants report their experience of genetic counselling (and testing where appropriate) for pancreas cancer (PC) susceptibility. They report multiple benefits, including improved understanding of genetic and environmental risks, reassurance and a motivation to help younger generations. Most are interested in genetic testing for PC susceptibility and want genetics review when further testing becomes available. We also assess the utility of PancPRO, a PC risk estimation model, to estimate a person’s individual risk based on their family history. Personalised risk assessments may improve risk communication and patient education during genetic counselling consultations.
CAF hierarchy driven by pancreatic cancer cell p53-status creates a pro-metastatic and chemoresistant environment via perlecan

Nat Commun. 2019 Aug 12;10(1):3637. doi: 10.1038/s41467-019-10968-6.
Aggressive pancreatic cancer cells change their environment (matrix) to enable easier spreading of the cancer (metastasis). This is done by a production of a molecule called ‘perlecan’ to remodel the matrix, easily allowing metastasis and also protecting them against chemotherapy. Together with targeting the cancer cells themselves with chemotherapy, there are important benefits in targeting the cells that produce the matrix, namely fibroblasts.

The paperwork required for contemporary research has drastically increased. One example is a Material transfer agreement (MTA) which is a common vehicle for exchanging materials. This paper investigates ways to minimise delays in research that requires access to materials on reasonable terms.

The complexities involved in returning genome-scale research results to study participants and the assessment of the impact on their clinical care and health outcomes have been analysed. The benefit of returning results can be substantial and valuable, even though it is labour-intensive and the rates of finding clinically applicable information are likely to be low in large-scale genomic studies.

This paper uncovers a promising new approach to treating pancreatic cancer by targeting the tissue around the tumour. This is done by a course of fasudil which is a drug that makes tumours softer and makes the blood vessels around tumours ‘leaky’. Subsequent treatment with standard-of-care chemotherapy for pancreatic cancer resulted in double the survival time and impaired metastasis.
