Virtual reality cognitive training during brain tumor radiotherapy
This trial tests whether a computer-based cognitive training program in a virtual reality setting can help children think and learn while they are getting radiation for a brain tumor. You and a parent will decide together if it’s a good fit, and the child must be able to complete the study tasks.
Memphis, TennesseeAges 8–22 - NCT05950594RecruitingPhase 2
MRI and blood tests study in soft tissue sarcoma
This Phase 2 trial looks at how two test approaches (an MRI-based scan and blood tests) work in people with a larger, grade 2 or 3 soft tissue sarcoma. It may help researchers learn better ways to measure the disease and guide care.
Toronto, OntarioAges 18–100 - NCT05943210Recruiting
Molecular testing of rectal cancer after short-course radiation
This study looks at molecular (tumor biology) features of rectal cancer in people receiving standard short-course radiation. Your tissue and/or samples may be used to better understand the cancer and how it responds to treatment.
Chicago, IllinoisAges 18–90 - NCT05946577Recruiting
Links tinnitus and hearing changes after head and neck cancer treatment
This study looks at how tinnitus (ringing in the ears) and hearing problems may develop after radiotherapy alone or with certain chemotherapy for high-risk head and neck cancer. The goal is to better understand who is more likely to experience these side effects.
