Ultrasound for arm tissue after breast cancer
This study uses ultrasound to examine arm tissue in women who have had breast cancer. It aims to see if ultrasound can reliably detect changes in arm soft tissue, which may help identify or prevent arm swelling and stiffness after treatment.
AntwerpAges 18 years+ - NCT06181656Recruiting
Pneumonia Vaccine Study for Esophageal and Liver Cancer Patients
This trial studies how well the pneumonia vaccine works in people with esophageal or liver cancer who have low white blood cell counts after chemoradiation. It aims to see if the vaccine can still protect them from infection.
Houston, TexasAges 18 years+ - NCT06181812Recruiting
Genetic testing for lung adenocarcinoma
This study looks at inherited genetic changes in people with a type of lung cancer called lung adenocarcinoma. The goal is to find gene variants linked to the disease, which may help guide future treatment decisions.

Testing a tool to guide treatment for triple-negative breast cancer
This study is testing a research tool that may help doctors choose the best treatment for people with advanced triple-negative breast cancer. You will have a biopsy and blood draw to help see how the tool works.
LondonAges 18 years+ - NCT06182657Recruiting
Nasopharyngeal cancer response to induction chemotherapy
This study looks at how well nasopharyngeal cancer (NPC) responds to the first round of chemotherapy before other treatments. It aims to see if the amount of tumor shrinkage can help predict outcomes and guide future care for people with advanced NPC.
Nanchang, JiangxiAges 18 years+ - NCT06182917Recruiting
MRD detection for ovarian cancer with low CA125
This study looks at whether a blood test (MRD) can predict how well treatment works for ovarian cancer patients who do not have high CA125 levels, helping doctors choose better therapies.
Chengdu, SichuanAges Any age - NCT06183268Recruiting
Proton therapy for head and neck cancer skin side effects
This study looks at how proton therapy affects skin in people with head and neck cancer. It aims to better understand and manage skin reactions during treatment.
Knoxville, TennesseeAges 18 years+ - NCT06184035RecruitingPhase 1/Phase 2
Testing a radioactive drug for advanced solid tumors
This trial tests a new radioactive drug, 177Lu-SN201, for people with advanced solid tumors that have not responded to other treatments. The goal is to see if it can shrink tumors and to find the best dose.
Adelaide, South AustraliaAges 18 years+ - NCT06183983Recruiting
Advanced MRI for better glioblastoma radiation
This trial tests whether using advanced MRI scans before radiation therapy can help doctors target the tumor more precisely and possibly improve outcomes for people with glioblastoma. It aims to make radiation treatment more personalized.
Rotterdam, South HollandAges 18 years+ - NCT06184152Recruiting
Comparing two scans to find liver cancer early
This trial compares two types of imaging scans (CEUS and AMRI) to see which one is better at finding liver cancer (HCC) in patients who have an unclear spot on their liver (an indeterminate nodule). It is for people with cirrhosis who have at least one such nodule but no confirmed liver cancer yet.
Ann Arbor, MichiganAges 18 years+ - NCT06184880Recruiting
Physical activity program for sedentary cancer patients
This trial tests whether a remote physical activity program can help reduce time spent sitting for people with new upper aerodigestive tract cancer. If you qualify, you may be able to take part in exercise sessions from home.
ValenceAges 18 years+ - NCT06184516RecruitingPhase 2
Bladder cancer study: testing a tool to see if womb and ovaries can be saved
This trial is testing a decision-making tool to help women with bladder cancer choose whether to keep their uterus, ovaries, and other pelvic organs during bladder removal surgery. It may help maintain quality of life after surgery.
Gainesville, FloridaAges 18–99 - NCT06184698RecruitingPhase 2
Liposomal irinotecan, chemotherapy, and bevacizumab for advanced colorectal cancer
This trial tests a combination of liposomal irinotecan, two chemotherapy drugs (leucovorin and 5-fluorouracil), and bevacizumab as a second-line treatment for people with colorectal cancer that has spread and cannot be removed by surgery.

This trial tests two procedures—irreversible electroporation and stereotactic body radiotherapy—for people whose colorectal cancer has spread to the liver (1–3 tumors near major blood vessels or bile ducts) and can't be surgically removed or treated with heat. The goal is to see if these approaches can safely destroy those hard-to-reach tumors.
