Watch-and-wait after chemo-radiation plus immunotherapy for esophagus cancer
This Phase 2 study tests whether adding an immunotherapy drug (camrelizumab) to standard chemo-radiation can help some people with operable esophagus cancer avoid immediate surgery, using a “watch and wait” approach. If it works, it may reduce the need for early surgery for carefully selected patients.
Hanzhou, ZhejiangAges 18–75 - NCT04108936Recruiting
Long-term study of CRS/HIPEC for cancer spread in the abdomen
This study follows people who have cancer that looks like it has spread along the lining of the abdomen. It looks at outcomes over time for a treatment called CRS/HIPEC, which is designed to remove tumor from the abdomen and bathe it with heated medicine.
Regensburg, BavariaAges 18–80 - NCT05529615Recruiting
Blood DNA test guides chemotherapy after colon cancer surgery
This trial checks a blood test called circulating tumor DNA to help choose the best time and approach for chemotherapy after colon cancer surgery. It aims to reduce recurrence by identifying people who may benefit from treatment based on changes seen in the blood.
Beijing, Beijing MunicipalityAges 18–75 - NCT05276037Recruiting
PET/CT scan to guide liver transplant decisions in liver cancer
This trial studies how a whole-body PET/CT scan using a “tracer” called 18F-FDG can help decide which people with liver cancer (HCC) may benefit from a liver transplant. It may help the transplant team better sort out who is likely to do well after transplant.
AntwerpAges 18–80 - NCT03308916Recruiting
Screening for liver scarring risk using noninvasive tests
This study checks people who are at higher risk for liver scarring by using noninvasive tests. If those tests suggest significant scarring, the study may consider further testing, but not everyone will need a biopsy.
OdenseAges 30–75 - NCT04389086RecruitingPhase 3
Chemotherapy before surgery for recurring rectal cancer
This trial tests an “induction chemotherapy” treatment before surgery for people whose rectal cancer has come back in the local area. The goal is to shrink/control the cancer early and improve outcomes after treatment.
GhentAges 18 years+ - NCT05524090Recruiting
Program to prepare for surgery in locally advanced pancreatic cancer
This trial studies an “implementation program” to help patients with locally advanced pancreatic cancer get ready for the next steps after chemotherapy. It may help improve care planning and outcomes for people whose cancer has not grown after initial treatment.
Amsterdam, North HollandAges 18 years+ - NCT05534906Recruiting
Detecting very early liver cancer and tracking its natural course
This study looks at how well doctors can detect small, early liver cancer and then follow how it changes over time. It may help your care team choose the best next steps based on earlier, clearer detection.
Oxford, OxfordshireAges 18–100 - NCT05539105Recruiting
Watching recovery after surgery for upper stomach cancer
This study keeps track of how people recover after surgery to remove the upper part of the stomach and nearby lymph nodes. It mainly helps doctors understand which surgical reconstruction methods work best and how patients do over time.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05541601Recruiting
Study to detect liver cancer early in people with cirrhosis
This study follows people with cirrhosis to see how best to detect liver cancer early. If you qualify, you may receive regular monitoring that could help find liver cancer sooner, when treatment is more likely to work.
Oxford, OxfordshireAges 18–100 - NCT05537129Recruiting
Laparoscopic vs open stomach surgery for stomach cancer
This trial compares two ways surgeons remove the entire stomach (total gastrectomy): laparoscopic (small keyhole cuts) versus open surgery (one larger cut). It’s testing which approach is safer and works better for people with certain stages of stomach cancer.
Shanghai, Shanghai MunicipalityAges 20–80 - NCT05528783Recruiting
Testing FIT-DNA to guide follow-up after colon cancer surgery
This trial checks a stool test called FIT-DNA after colorectal (colon) cancer surgery. It aims to see whether this test can help doctors monitor for recurrence during follow-up and decide how closely to watch.
Guangzhou, GuangdongAges 18–80 - NCT03948438Recruiting
Endoscopic treatment for Zenker’s diverticulum symptoms
This trial looks at an endoscopic (camera-based) procedure to help symptoms from Zenker’s diverticulum, which is a swallowing-related pouch. If you have symptoms and you’re not pregnant or breastfeeding, this study may be worth considering.
RozzanoAges 18 years+ - NCT05408897Recruiting
Blood test to predict risk after surgery for high-risk GIST
This study uses a “liquid biopsy” blood test to look for leftover cancer signals after surgery. It aims to predict how well treatment will work and how likely the cancer is to come back in people with high-risk GIST.
Beijing, Beijing MunicipalityAges Any age - NCT05546086Recruiting
Beijing health study for adults who live in Beijing
This study collects health information from adults (18+) who are permanent residents of Beijing. It aims to learn patterns about health in the local population and how different factors may affect outcomes over time.
BeijingAges 18 years+ - NCT05547529RecruitingPhase 3
Chemo and radiation before surgery versus chemo alone for esophageal cancer
This trial studies whether adding radiation to chemotherapy before surgery works better for people with operable (resectable) squamous cell esophageal cancer. It aims to improve outcomes by comparing two different treatment plans before the operation.
MoscowAges 18–70 - NCT04673955Recruiting
Real-world treatment study for metastatic bowel cancer with BRAF mutation
This real-world study looks at how doctors’ standard treatment works for metastatic colorectal cancer that has a specific BRAF mutation (BRAF V600E). It focuses on patients who are already starting—or will soon start—encorafenib plus cetuximab, using routine care rather than extra trial treatment.
Braunau am Inn, Upper AustriaAges 18 years+ - NCT03747588Recruiting
Laparoscopic versus open surgery for pancreas cancer
This study compares two ways of doing pancreaticoduodenectomy (a major surgery to remove parts of the pancreas and nearby tissue): minimally invasive (often smaller incisions) versus open surgery. It may help clarify which approach works best when the cancer looks potentially removable.
Beijing, Beijing MunicipalityAges 18–75 - NCT05563922RecruitingPhase 2
Testing a plan to preserve the anus after rectal chemo-radiation
This Phase 2 study tests a “total neoadjuvant” (chemo plus radiation before the main treatment) plan to see if some people with low rectal cancer can keep their anus. It may help you avoid permanent colostomy if your cancer responds well and you meet the study rules.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05563012RecruitingPhase 2
Short radiation plus chemo and PD-1 immunotherapy for stomach cancer
This Phase 2 trial tests whether giving a short course of radiation before surgery, along with chemotherapy and a PD-1 immunotherapy drug, can improve treatment outcomes for locally advanced stomach cancer. It may help shrink the tumor before surgery and strengthen the immune system’s attack on cancer.
Wuhan, HubeiAges 18–75 - NCT03280511RecruitingPhase 2
After surgery chemo sprayed into the abdomen for high-risk colon cancer
This Phase 2 study tests whether spraying chemotherapy into the abdomen (through a small procedure) after colon cancer surgery can lower the chance the cancer comes back. It is meant for people with high-risk tumor features but who have had surgery and have no proven relapse yet.
OdenseAges 18 years+ - NCT04280822RecruitingPhase 3
Immunotherapy plus chemo versus chemo alone before surgery
This Phase 3 trial tests whether adding immunotherapy to chemotherapy before surgery works better than chemotherapy alone for resectable esophageal cancer. The goal is to improve outcomes after tumor shrinkage before the operation.
Zhengzhou, HenanAges 18–75 - NCT05566249Recruiting
Safety study of ArtiSential during rectal cancer surgery
This trial checks whether a tool called ArtiSential can be used safely and practically during planned rectal cancer operations. It may help the surgical team prepare and perform the operation more smoothly, but the main goal is safety and feasibility.
SeoulAges 18–80 - NCT04527861Recruiting
Minimally invasive single-incision surgery for colon cancer
This trial compares a single-incision laparoscopic operation versus the usual laparoscopic operation for colorectal (colon or “high rectum”) cancer. It looks at cancer outcomes and may help determine which approach is safer and works better for the right patients.
