Before-surgery chemotherapy vs immediate surgery for colon cancer
This trial compares giving chemotherapy before surgery versus going straight to surgery for certain stage II/III colon cancers. It may help shrink the tumor and improve outcomes by testing which approach works best for high-risk cases.
Guangzhou, GuangdongAges 18–75 - NCT05206890Recruiting
Registry study of fluzoparib for ovarian, tube, or peritoneal cancer
This is an observational (non-interventional) study that tracks how fluzoparib is used to treat ovarian, fallopian tube, or primary peritoneal cancer in real-world care. It may help doctors better understand how well the treatment works and what side effects patients experience.
Wuhan, HubeiAges 18 years+ - NCT04974346RecruitingPhase 3
Radiation to prevent spread in cervical cancer lymph nodes
This Phase 3 trial tests whether adding a preventive radiation treatment to lymph node areas near the abdomen helps stop cervical cancer from spreading. It aims to improve outcomes for people with certain cervical cancer stages and lymph node results on PET-CT.
Hangzhou, ZhejiangAges 18–75 - NCT04947059RecruitingPhase 3
Stop bladder cancer coming back with medicine after bladder surgery
This trial tests whether putting chemotherapy medicine directly into the bladder right after surgery helps prevent bladder cancer from coming back. It compares gemcitabine versus epirubicin given as an immediate bladder “wash-in.”
Larissa, Larissa/ThessalyAges 18–100 - NCT04712305Recruiting
Urine test to predict kidney cancer response to immunotherapy
This study uses an at-home-style urine test (urine “omics,” meaning detailed lab information) to help predict how well immunotherapy may work for advanced kidney cancer. If you join, your urine results may help doctors tailor treatment choices and better understand who benefits most.
TaipeiAges 20 years+ - NCT05044117RecruitingPhase 3
Capecitabine pills after chemoradiation for head and neck cancer
This trial tests whether taking capecitabine pills on a steady, low schedule after standard treatment can help keep locally advanced head and neck squamous cell cancer from coming back or spreading. You may be eligible if your cancer is stage III–IV and you have finished certain radiation/chemo treatments on time, without current spread.
Guangzhou, GuangdongAges 18–70 - NCT05221372Recruiting
Sampling study for lung cancer patients on targeted pills
This trial collects blood samples from adults with advanced lung cancer that has a specific gene change and who are already taking targeted pill treatment (TKIs). The goal is to learn from these samples and how they relate to the cancer in patients on standard therapy.
RotterdamAges 18 years+ - NCT05241119Recruiting
Lymph node mapping to guide surgery after chemotherapy
This study tests using a special carbon-based tracing method to help doctors check which lymph nodes to treat during surgery after you finish chemotherapy. It may improve how accurately the surgical plan targets cancer in the armpit (axillary) lymph nodes.
Shenyang, LiaoningAges 18–70 - NCT05246475Recruiting
PET-MRI scan study for oxygen levels in head and neck tumors
This study uses a combined PET-MRI scan to measure how much oxygen a head and neck tumor has. It may help doctors understand tumor “oxygen levels,” which can relate to how tumors grow and respond to treatment.
Turku, G102881Ages 18–80 - NCT04845828Recruiting
Sentinel node biopsy versus full node removal in early uterine cancer
This study compares two ways to check lymph nodes during surgery for early-stage endometrial (uterine) cancer: sentinel node biopsy versus removing more lymph nodes. It may help find whether the less extensive approach can stage the cancer accurately with fewer side effects.
SeoulAges 20–80 - NCT05257434Recruiting
Body composition test after liver, bile duct, or pancreas cancer surgery
This study looks at how well people do after surgery for liver, bile duct, or pancreas cancer, using a body composition test (the “inBody” test). It may help doctors understand which body changes after surgery are linked to better or worse recovery.
KochiAges 18–90 - NCT04007783Recruiting
Test of a new plan for jaw reconstruction and implants
This study checks whether the “O-bridge protocol” helps people who need jaw surgery—either for osteonecrosis of the jaw or for oral/jaw tumors—followed by dental implant placement to support fixed teeth (not removable dentures). The goal is to improve your ability to eat, speak, and get a stable tooth replacement plan after surgery.
AntwerpAges 18 years+ - NCT05242861Recruiting
Reviewing outcomes after brachytherapy for women’s cancers
This study looks back at medical records to understand results after brachytherapy (a form of cancer radiation delivered from inside or close to the tumor) in women with gynecologic cancer. It may help doctors improve future treatment decisions, but you would not have to receive an experimental treatment.
Hangzhou, ZhejiangAges 18–80 - NCT05266534Recruiting
Terlipressin or oxytocin during open fibroid surgery
This trial compares two injected medicines (terlipressin vs carbetocin) given into the uterus during open fibroid (myomectomy) surgery to see which one reduces blood loss and helps maintain hemoglobin. It may help patients by targeting lower bleeding during surgery.
MaadiAges 16–40 - NCT04787354RecruitingPhase 3
Choosing the best length of oxaliplatin after stomach surgery
This trial tests whether giving oxaliplatin for a shorter or longer time works best after curative surgery for stage II–III stomach (or stomach–esophagus junction) cancer. It aims to improve outcomes while balancing side effects from chemotherapy.
Gyeonggi-doAges 19 years+ - NCT05268692RecruitingPhase 2/Phase 3
Pancreatic cancer chemo before surgery, then two drug combinations
This trial studies giving chemotherapy before planned surgery for pancreatic cancer, followed by additional treatment with two drug combinations. It may help shrink the cancer and improve how well surgery works.
KochiAges 18–85 - NCT05260619RecruitingPhase 2
Lenalidomide after response for primary brain lymphoma
This trial studies lenalidomide taken after your first treatment has worked for primary central nervous system lymphoma (PCNSL). It aims to help keep the lymphoma from coming back by testing lenalidomide as ongoing “maintenance” treatment.
Seongnam-si, Please SelectAges 19 years+ - NCT04363983Recruiting
Study of immune and tumor interactions in digestive cancers
This study looks at how tumors in the digestive system interact with the body’s immune system and the surrounding environment. Results may help improve understanding of these cancers and guide future treatments.
Boulogne-BillancourtAges 18 years+ - NCT04480203Recruiting
Digital coping tools after new breast cancer diagnosis
This trial tests two online programs designed to help people cope after being diagnosed with breast cancer. It may help you manage stress and emotions during treatment or recovery.
OsloAges 20–69 - NCT02661139Recruiting
Registry of jaw reconstruction for cancer patients who need implants
This study is a “real-world” registry that follows people with jaw problems related to cancer or cancer treatment. It looks at how well jaw reconstruction with dental implants and fixed teeth works when removable dentures are not suitable.
BrugesAges Any age - NCT03785743Recruiting
Compare keyhole vs open surgery for pancreatic cancer
This trial compares two ways of doing surgery for pancreatic cancer: keyhole (small cuts) versus open surgery (one larger cut). It’s meant to see which approach works better for people who are well enough for either option.
Wuhan, HubeiAges 18–75 - NCT04682470Recruiting
Research study following young adults with cancer
This is an observational study that follows young adults with a confirmed cancer diagnosis to learn more about their experience and care. It does not test a new drug, but your information may help improve future cancer treatment and support.
Amsterdam, North HollandAges 18–39 - NCT05201430RecruitingPhase 3
FOLFOXIRI vs CapeOX before surgery for locally advanced rectal cancer
This trial compares two chemotherapy plans given before rectal cancer surgery to see which helps more people and works better for disease control. If you have locally advanced rectal cancer and have not had treatment yet, this study may be an option.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04190849Recruiting
Children’s liver fat disease registry in Europe
This is a registry study collecting information about children and teens with fatty liver disease that isn’t caused by alcohol. It aims to better understand this condition and may help future research and treatments.
