MR-guided linac boost for gynecologic cancers when brachytherapy isn’t possible
This study tests a targeted radiation “boost” delivered using an MRI-guided machine for certain gynecologic cancers when the usual treatment (brachytherapy) can’t be done. It may help improve control of the cancer while still aiming for cure.

Safety study of laparoscopic surgery for large stomach GISTs
This study looks at how safe laparoscopic surgery is for stomach GISTs that are 5 cm or larger. If you’re eligible and choose to participate, your team will plan and perform surgery and track safety outcomes.
Fuzhou, FujianAges 18–75 - NCT05938322Recruiting
Ketogenic diet during pelvic cancer radiation treatment
This trial studies whether a very low-carbohydrate (ketogenic) diet can be followed safely while you receive neoadjuvant radiation for locally advanced rectal cancer. It may help researchers understand effects related to nutrition and treatment tolerance during radiation.
RomeAges 18–75 - NCT05938192Recruiting
Treatments for HPV-related genital tract changes
This trial studies treatment approaches for conditions caused by human papillomavirus (HPV) in the female genital tract. It may help people whose HPV-related disease is being evaluated for new or combined treatment options.
Milan, LombardyAges 18 years+ - NCT05939063Recruiting
Testing two surgery approaches for early left pancreatic cancer
This trial compares two ways of doing surgery in people with early, left-sided pancreatic cancer that can be removed. It may help find the approach with better outcomes while aiming to keep the operation safe and effective.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05939401Recruiting
Tissue study during and after anal cancer treatment
This study looks at how anal cancer tissue and samples change during and after treatment. Your participation may help doctors understand treatment response, especially for people with newly diagnosed or returning anal cancer.
GothenburgAges 18 years+ - NCT05939830Recruiting
Skipping axillary lymph node surgery after treatment response
This study looks at whether some breast cancer patients can safely skip a surgery that removes lymph nodes in the armpit after their initial (pre-surgery) treatment shows the armpit is likely clear. It may reduce surgical side effects if the armpit truly responds well.
NanjingAges 18–70 - NCT05939661RecruitingPhase 2
Total treatment before surgery for early rectal cancer
This Phase 2 study tests a “total neoadjuvant” approach, meaning you receive cancer treatment before surgery, to improve safety and effectiveness for rectal cancer. It may help by shrinking the tumor and planning a more effective operation, while researchers carefully track side effects.
OsakaAges 18 years+ - NCT05939687RecruitingPhase 3
Mesh placement to help prevent complications after bowel surgery
This Phase 3 trial tests whether placing a protective mesh during stoma closure can lower the risk of complications after low anterior resection surgery. It may help people heal more safely and reduce stoma-related problems.
MoscowAges 18–85 - NCT05940272Recruiting
Communication training for doctors treating large B-cell lymphoma
This study tests a communication training program for providers who care for people with large B-cell lymphoma. The goal is to improve how clinicians talk with patients, especially during difficult treatment periods like relapse.
New York, New YorkAges 18 years+ - NCT05940259Recruiting
68Ga PET/CT scan for prostate cancer imaging
This trial looks at a specific PET/CT scan using a tracer called 68Ga to create detailed images of prostate cancer. It may help doctors see where cancer is in the body more clearly.
Beijing, Beijing MunicipalityAges 18–75 - NCT05940415Recruiting
Active surveillance without prostate biopsy for low-risk suspects
This study checks whether people with a low chance of prostate cancer can be monitored closely without having an immediate prostate biopsy. It uses PSA blood tests and prostate MRI to sort who may safely wait.
Hefei, AnhuiAges 18 years+ - NCT05940311Recruiting
Blood test for melanoma with BRAF V600E mutation
This trial studies a very sensitive blood test to detect melanoma-related genetic changes in people with BRAF V600E. It may help track the disease more closely and guide care in advanced or high-risk situations.
RomeAges 18 years+ - NCT05940532RecruitingPhase 2
Sutimab plus chemotherapy for advanced lung cancer needing radiation
This trial tests a cancer-fighting antibody (sugemalimab) added to standard chemotherapy for stage III lung cancer that can’t be removed by surgery but may be treated with radiation. It aims to improve control of your cancer while checking safety and side effects.
ChangshaAges 18–75 - NCT05940493RecruitingPhase 2
Abemaciclib for newly diagnosed grade 3 meningioma
This trial tests abemaciclib, a targeted medicine, to see if it can help people with newly diagnosed grade 3 meningioma after standard radiation treatment. It may help by slowing tumor growth or improving outcomes after initial therapy.
