Researchers are studying the effects of adding olaparib, a PARP inhibitor, after surgery and chemotherapy in patients with pancreatic cancer that has been surgically removed and who have mutations in BRCA1, BRCA2, or PALB2 genes. This phase II trial aims to see if olaparib can improve relapse-free survival compared to placebo. The study also evaluates overall survival and differences in outcomes based on mutation type and prior chemotherapy treatment. Participants are randomly assigned to receive either olaparib or a placebo orally twice daily in 28-day cycles for up to 12 cycles, unless the disease progresses or side effects occur. During the treatment, patients will have CT or MRI scans and blood samples taken regularly. After treatment, participants will be followed up at 30 days, every 4 months for the first year, then every 6 months for up to 10 years. Throughout the study, patients will undergo imaging and blood tests to monitor their health and detect any recurrence of cancer. The main outcome measured is the time from randomization to disease recurrence or death. Researchers will also track overall survival for up to 10 years. Safety will be monitored, and participants will be observed regularly after treatment to assess long-term effects and disease status.

Researchers are collecting blood and tissue samples from people with and without cancer to help evaluate new tests that could detect cancer early. This study aims to create a set of blinded blood samples from both cancer and non-cancer patients to validate these tests, focusing on multiple cancer types and stages. The goal is to improve early cancer detection through laboratory research. Participants complete a questionnaire at the start and provide blood samples at registration and again 12 months later. Those diagnosed with cancer may also have tissue samples collected at these times. The study includes patients with various cancer types and stages, as well as individuals without cancer, with some allowing enrollment before full cancer confirmation under specific conditions. During the study, researchers review the collected samples and questionnaire data to assess test performance by tumor type and clinical stage at diagnosis. Participants are followed for one year after completing the study. Key measurements include the provision of a blinded reference set of cancer versus non-cancer blood samples to support future clinical trials focused on blood-based multi-cancer early detection.

Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

This research aims to compare two methods of monitoring pancreatic cysts and to identify biomarkers that may help detect the risk of these cysts turning into pancreatic cancer. The study evaluates whether more frequent monitoring or less frequent monitoring leads to better patient outcomes and explores various blood and imaging biomarkers for improved risk prediction. Participants are observed through two different surveillance approaches that were previously randomized but are now closed to new enrollment. One approach involves lower intensity monitoring with MRI, CT, or endoscopic ultrasound EUS scans spaced out over years, while the other involves higher intensity monitoring with more frequent imaging based on cyst size. Throughout the study, patients may also provide blood samples and undergo biopsies, fine needle aspirations, or surgery as needed. Participants are followed up regularly for five years from registration, with imaging and blood tests at intervals depending on their assigned monitoring method. Researchers collect data on clinical features, anxiety, quality of life, financial distress, healthcare costs, and outcomes such as the development of concerning pancreatic cyst features or pancreatic cancer. The study uses these measures to assess the effectiveness of monitoring strategies and the predictive value of biomarkers.
