CONTROL NETs TR
CONTROL NETs translational substudy
Principcal Investigator: Dr Ben Lawrence
Tumour: NeuroEndocrine Tumours (NETs)
Peptide Receptor Radionuclide Therapy (PRRT) is an effective treatment for neuroendocrine tumours (NETs). CONTROL NETs, an AGITG study in follow up, tested whether adding chemotherapy to PRRT will make it more effective, the results are currently demonstrating an encouraging increase in tumour shrinkage. Normally we know who can benefit from PRRT, because their NET tumours will light up on a special type of PET scan (Gallium68 PET). However, we don’t have a way of knowing which patients will benefit from adding chemotherapy to the PRRT. The most likely way of finding who will benefit from chemotherapy is testing for a gene called MGMT.
This substudy of the CONTROL NETs trial will investigate whether testing MGMT in several ways at the same time (‘multi-omic testing’), and combining the results of these tests, can predict who will benefit from adding chemotherapy to PRRT. If it works, we will be able to identify who needs to have chemotherapy with PRRT, and who can have PRRT on its own.
MASTERPLAN Microbiome Substudy
Understanding the effect of chemotherapy on microbial composition of pancreatic ductal adenocarcinoma (PDAC) patients
Principal Investigator: Prof David Goldstein
Tumour: Pancreatic Cancer
Pancreatic cancer is the fourth most common cause of cancer death in Australia and it is critical to develop a new treatment for patients with pancreatic cancer who have limited life expectancy. Increasing body of research suggest that bacteria within human body may be responsible for the development and survival of pancreas cancer. There is an emerging idea that changing gut bacteria may improve the effects of chemotherapy.
The MASTERPLAN Microbiome study is a translational research substudy within the MASTERPLAN trial to collect serial bacterial samples from patients receiving chemotherapy as part of MASTERPLAN trial. The main goal is to describe how the gut bacteria will change before and after chemotherapy.
MASTERPLAN Proteomics Substudy
Principal Investigator: A/Prof Michelle Hill
Tumour: Pancreatic Cancer
Glycoprotein biomarkers are special proteins that can be used for early detection and monitoring the course of disease progression. Glycoprotein biomarkers may have prognostic value for pancreatic cancer. Through analysis of GAP trial patient samples collected prior to surgery and chemotherapy, we were able to identify proteins that correlated with overall survival (2 years), and proteins that correlated with progression free survival (1 year).
MASTERPLAN Proteomics substudy plans to measure serum levels of glycoprotein biomarkers using multiple reaction monitoring (MRM). The substudy will comprise 60 pretreatment samples from the MASTERPLAN trial.
Radiological And subjective measures of Nutrition, Diet and sarcOpenia – a Masterplan Substudy
Principal Investigators: Ms Belinda Steer and Ms Katie Benton
Tumour: Pancreatic Cancer
Pancreatic cancer is associated with a high prevalence of weight loss and malnutrition, and evidence suggests that changes in body composition, which means changes in the amount of muscle, fat, fluid and/or other tissues in our body, affects outcomes in all stages of pancreatic cancer. A loss of muscle tissue can impact general function and well-being, as well as the development of side effects from cancer treatment. Identifying and treating this early, through improved assessment techniques, could lead to improved outcomes for patients with PC.
A simple measurement of weight, or body mass index (BMI), as is currently commonly used, does not accurately identify those at most risk, or changes in muscle tissue. The most accurate way to measure body composition, using CT scans, requires skilled staff and is time consuming. In comparison, malnutrition and loss of muscle mass can be identified with a quick-to-use tool called the Patient Generated Subjective Global Assessment (PG-SGA). The PG-SGA is commonly used by dietitians when completing nutrition assessments in patients with pancreatic cancer. The relationship between the PG-SGA malnutrition diagnosis and CT-diagnosed low muscle mass has not yet been investigated in pancreatic cancer. Given the PG-SGA tool is widely accessible and low cost, comparing its use to the gold standard CT-assessed body composition is warranted. This may improve the management of patients with pancreatic cancer in the future.
This substudy of MASTERPLAN aims to identify how a standard instrument used by dietitians to assess for malnutrition performs against a gold standard.
RANDoMS is currently recruiting at select MASTERPLAN sites.
Fear of Recurrence Substudy
Principal Investigator: A/Prof Sue-Ann McLachlan
Tumour: Colorectal Cancer and Rectal Cancer
Fear of Cancer Recurrence (FCR) is defined as “fear, worry, or concern relating to the possibility that cancer will come back or progress” and is one of the most common unmet needs for help amongst cancer survivors. Previous research also suggests that FCR is not associated with objective risk of recurrence; rather that FCR may remain high in some individuals even when risk of recurrence is low. The availability of a growing number of genomic assays to predict risk of cancer recurrence across several cancer types no studies have investigated the relationship of being informed of high-risk of recurrence based on genomic profiling or forgoing standard therapy based on a low- risk genomic profile, and FCR.
Personalised medicine is likely to bring about new challenges with respect to FCR. A better understanding will allow clinicians to detect and direct those with significant FCR to psychological help and supportive care. This study will provide the first information about FCR when using molecular information to determine adjuvant chemotherapy for patients with stage III colon cancer and advanced rectal cancer.
The aim the Fear of Recurrence Substudy is to assess Fear of Cancer Recurrence levels using a validated self-reporting questionnaire in the context of a randomised clinical trial (the DYNAMIC-III study and DYNAMIC-Rectal).
Fear of Recurrence substudy is currently recruiting at DYNAMIC-III and DYNAMIC-Rectal sites.
