Cancer of unknown primary site

This study tests the immunotherapy drug atezolizumab in 200 people with advanced solid tumors (breast, lung, GI, and others). Researchers use each person's tumor DNA to see if it predicts a response. Participants get the same dose every 3 weeks. The goal is to see if DNA analysis…

This early-phase study tests whether adding the experimental drug ipatasertib to standard chemotherapy and radiation is safe and effective for people with advanced head and neck cancer. Ipatasertib may help stop cancer cell growth. About 46 participants will receive the combinati…

This trial is testing whether adding an experimental drug called F520 to standard chemotherapy (paclitaxel plus carboplatin) helps people with cancer of unknown primary — a cancer that has spread but whose original site cannot be found. About 402 adults aged 18 to 75 who have not…

This early-phase trial is testing whether adding the immunotherapy drug pembrolizumab (Keytruda) to radiation therapy before and during surgery can help treat head and neck cancers that have persisted or come back. About 45 adults with resectable tumors will receive the combinati…

This study tests the drug nivolumab in people with advanced rare cancers that have a specific marker (PD-L1). The goal is to see if the drug can shrink or control the tumors when other treatments have stopped working. Up to 28 adults will receive treatment for up to 12 months, an…

This phase 2 trial is testing whether the immunotherapy drug dostarlimab can work better than standard chemotherapy as a first treatment for people with rare, advanced cancers that have a specific genetic flaw called dMMR/MSI. The study includes 120 adults with cancers like pancr…

This early-stage trial is testing a powerful mix of five chemotherapy drugs for people with advanced upper gastrointestinal cancers, including pancreatic and stomach cancers. The study uses each person's genetic profile to adjust the dose of one of the drugs (irinotecan) to try t…

This study is testing a new tool that uses DNA methylation patterns to figure out where a cancer started when doctors can't find the original tumor. Researchers will analyze tissue samples from 120 people with cancer of unknown primary. If it works, this could help guide more per…

This study tests a dye called pegsitacianine that makes cancer cells glow during surgery. It is for 120 adults with head and neck cancer, including those with an unknown primary tumor. The goal is to see if the dye helps surgeons find and remove all cancer tissue safely.

This study aims to learn more about oropharyngeal carcinoma, a type of throat cancer that can be linked to HPV. Researchers will collect blood samples from 1,000 patients before treatment and at six follow-up visits, and also gather tumor tissue when available. The goal is to bet…

This study enrolls 7,000 people with various cancers who have had or will have treatment aimed at a cure. Researchers collect blood, tissue, urine, and saliva samples over time to look for tiny bits of cancer DNA left behind. The goal is to find any remaining cancer as early as p…

This study tests whether offering hearing tests close to home or remotely increases how many head and neck cancer patients get their hearing checked during treatment. Many patients on cisplatin chemotherapy or radiation near the ear can lose hearing, but not all complete recommen…

This study is building a huge registry of information and biological samples from adults with or at risk for many types of cancer, as well as healthy volunteers. Researchers will use this resource to study what causes cancer and how to better prevent, detect, and treat it. The re…

This study aims to collect and analyze tumor samples from 10,000 adults with advanced solid cancers (like breast, lung, or colon cancer) to create a province-wide gene database. The goal is to help doctors identify which targeted drugs or clinical trials might work best for each …

This study is testing whether genetic testing of tumors and blood can help doctors choose better treatments for people with rare cancers. About 400 adults with rare solid tumors or lymphomas will have their tumors genetically analyzed. A team of experts will review the results an…

This study looks at why people with head and neck cancer follow (or don't follow) swallowing exercises after radiation. Researchers will use blood tests and questionnaires to see if immune system proteins or feelings about the disease affect exercise habits. The goal is to find w…

This study is looking at how cancer genetic testing works in people from different ethnic backgrounds. Researchers will collect blood samples and genetic information from 1,800 adults with various solid tumors. The goal is to find cancer-related gene mutations and see if current …

Cancer of Unknown Primary (CUP) is a rare cancer where doctors cannot find where it started, and it is often deadly within months. This study will test a blood-based genomic test in 100 people with CUP to see if it can find genetic changes that point to new treatment options. The…

This study is testing a computer model called the CLOVER score, which uses machine learning to predict whether a person with a blood clot might have an undiagnosed cancer. Researchers will check the model's accuracy in 500 patients over two years. If it works well, doctors could …
