Laparoscopic surgery for gynecological and remote procedures
This trial tests a laparoscopic surgical system for gynecological and remote surgeries. It may help patients who need minimally invasive surgery and can follow the study plan.
Nantong, JiangsuAges 18–80 - NCT06643793RecruitingPhase 2
Irinotecan liposome combo for advanced colorectal cancer
This trial tests a new form of the chemotherapy drug irinotecan (called irinotecan liposome) combined with two other chemo drugs and a targeted therapy (bevacizumab) for people with advanced colorectal cancer that has already been treated with oxaliplatin. The goal is to see if this combination can shrink tumors or slow the cancer's growth.
Nanjing, JiangsuAges 18–75 - NCT06522919RecruitingPhase 2
Immunotherapy and chemotherapy for advanced colorectal cancer
This trial tests a sequence of treatments for people with a specific type of advanced colorectal cancer (called pMMR or MSS) that has not responded to earlier therapies. Patients first receive an immunotherapy combination (pembrolizumab plus a personalized dendritic cell vaccine) followed by a chemotherapy pill (trifluridine/tipiracil) plus bevacizumab. The goal is to see if this sequence can help control the cancer.
Meldola, Forlì CesenaAges 18 years+ - NCT06685289RecruitingPhase 2
Donafenib and capecitabine after surgery for biliary cancer with high risk of return
This trial tests whether taking donafenib and capecitabine pills after surgery can help prevent biliary cancer from coming back in people who have a high risk of recurrence. It is for patients whose cancer was completely removed but had certain features that make recurrence more likely.
Nanjing, JiangsuAges 18–75 - NCT06707233RecruitingPhase 2
Y-90 radioembolization for large liver cancer (over 7 cm)
This trial tests a treatment called Y-90 radioembolization (SIRT) for people with liver cancer that is too large to be removed surgically. The treatment delivers tiny radioactive beads directly to the tumor through the liver's blood supply, which may shrink the tumor and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT06796634Recruiting
Cold plasma for cancer in the abdomen
This trial tests whether a special cold gas (called cold atmospheric plasma) can help destroy cancer cells left in the abdomen after surgery. It's for people with certain cancers that have spread to the belly lining.
Ghent, East-FlandersAges 18 years+ - NCT06796270Recruiting
Short-course radiation for nasopharyngeal cancer
This trial tests a shorter course of radiation therapy for people with nasopharyngeal cancer, a type of head and neck cancer. The goal is to see if a hypofractionated (fewer, larger doses) approach is safe and effective.
Haikou, HainanAges 18–75 - NCT04859530Recruiting
Smartphone AI test for cervical cancer screening
This study checks whether a smartphone-based AI tool can help screen for cervical cancer. You may be offered the AI-assisted screening during a clinic visit to see if it works well when visualizing the cervix.
Dschang, MenouaAges 30–49 - NCT06796517Recruiting
Immunotherapy for relapsed or refractory lymphoma
This trial tests immunotherapy for people with certain types of lymphoma (diffuse large B cell, primary mediastinal, high grade, or Burkitt) that came back or didn't respond to previous treatment. It aims to see if a new immune-based approach can help.
SeoulAges 19–74 - NCT04929912Recruiting
Registry for people treated with electroporation for cancer
This study is a real-world registry that collects information about people who have already received cancer treatment using electroporation methods. It may help researchers learn which treatments are used in practice and what outcomes people experience.
LondonAges Any age - NCT04957511Recruiting
Testing gut bacteria in gynecologic cancer patients on immunotherapy
This study looks at how gut bacteria may relate to how well immunotherapy works in people with advanced or returning gynecologic cancer. You may be asked to give stool samples several times so researchers can measure changes in your gut microbiome.
Orlando, FloridaAges 18 years+ - NCT05451303Recruiting
Testing for oral and throat cancer risk with a mouth test
This trial studies how well an at-home or clinic mouth test (OralViome Cancer Testing System) can detect signs of risk for oral or throat cancer. You may benefit by getting cancer-risk testing if you are considered high risk, though results will guide whether further evaluation is needed.
New York, New YorkAges 18 years+ - NCT05841420RecruitingPhase 2
Lower-intensity chemo for fragile pancreatic cancer patients
This Phase 2 trial compares a standard gemcitabine approach versus a reduced-dose combination chemotherapy for people with pancreatic cancer that can’t be removed by surgery. It aims to find a treatment that works while being safer for “fragile” patients who can’t tolerate full-dose chemotherapy.
AalborgAges 18 years+ - NCT05937438RecruitingPhase 1/Phase 2
Radiation then immunotherapy after esophagus surgery
This trial studies giving radiation right after esophagus surgery, followed by immunotherapy, to keep the cancer from coming back. It is for people with a specific type and stage of esophageal squamous cell carcinoma.
Hefei, AnhuiAges 18–75 - NCT05911230Recruiting
MRI test to tell tumor return from temporary treatment effects
This study uses an advanced MRI scan to help doctors tell the difference between true tumor regrowth and “pseudoprogression,” which is a temporary treatment-related change that can look like progression. If it works, it may guide the safest next steps, including whether surgery is helpful.
BaselAges 18 years+ - NCT06174428Recruiting
Study of a new oral and throat cancer test
This study is testing a new, simple test that looks for signs of oral or throat cancer. If you have a suspicious spot or symptom, this test might help find out if it's cancer.
St Louis, MissouriAges 18 years+ - NCT06729346Recruiting
Finding hidden tumors during bladder cancer surgery
This study tests if a special light (NBI) can find bladder tumors that standard white light misses during surgery. It may help ensure more complete tumor removal.
Rawalpindi, Punjab ProvinceAges 18–75 - NCT06492395RecruitingPhase 3
Three treatments for large liver cancer with portal vein spread
This trial tests adding a second liver-directed treatment (hepatic artery infusion) to the usual combination of targeted therapy (lenvatinib) and chemoembolization (DEB-TACE) for people with large liver cancer that has spread into the portal vein, to see if the triple therapy works better.
Guangzhou, GuangdongAges 18–75 - NCT06324721Recruiting
Understanding arm swelling after breast cancer treatment
This study looks at why some people feel arm swelling (lymphedema) after breast cancer treatment even when tests don't show swelling. It follows people who are about to have breast surgery with lymph node removal and checks how they feel over time.
Leuven, Vlaams-BrabantAges 18 years+ - NCT06620627Recruiting
Blood test for early cancer detection before colonoscopy
This study is testing a new blood test that might help find cancer early. If you are 40 or older and planning a routine screening colonoscopy, you may be able to join. You will give a blood sample before the colonoscopy, and the researchers will see if the test can detect signs of cancer.
Austin, TexasAges 40 years+ - NCT06626672Recruiting
Digital Health Program for Kids with Heart Defects
This study uses digital tools to promote healthy habits in children (ages 8–14) with congenital heart disease. It aims to support both the child and their family in staying active and well.

Antibiotics before surgery for advanced rectal cancer
This trial tests if taking antibiotics before standard treatment can improve outcomes for people with advanced rectal cancer that requires surgery.
São Paulo, São PauloAges 18 years+ - NCT06799793Recruiting
AI screening for early colorectal cancer detection
This study uses an artificial intelligence model to analyze test results from the fecal immunochemical test (FIT) to help find colon cancer early. You may benefit if you are 50-69 and had a positive FIT result as part of a screening program.
