Short-course proton vs photon radiation before rectal surgery
This study compares two types of pre-surgery radiation—protons versus standard photons—in people with high-risk rectal cancer. The goal is to shrink and control the tumor while safely getting you ready for surgery, and to see which approach works better.
Stockholm, SolnaAges 18 years+ - NCT04539977RecruitingPhase 2
PD-L1 antibody plus chemotherapy for limited-stage small-cell lung cancer
This Phase 2 study tests whether adding a PD-L1 antibody to chemotherapy helps people with newly diagnosed limited-stage small-cell lung cancer live longer and control the cancer better. It may benefit patients who have not had any prior cancer treatment for SCLC and can meet health and lab requirements.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04541654Recruiting
Study of families with TP53 gene changes in Li-Fraumeni syndrome
This study is looking at how people in families with certain TP53 gene changes (including Li-Fraumeni syndrome) develop health problems over time. It may help doctors better understand risk and improve care for affected families.
Boston, MassachusettsAges Any age - NCT04547166RecruitingPhase 2/Phase 3
New targeted immune drug plus bevacizumab and chemo for colon cancer
This trial studies serplulimab (an immune-related drug) together with bevacizumab and chemotherapy to treat metastatic colorectal (colon) cancer that cannot be removed with surgery. It aims to see whether this combination improves outcomes and is safe.
Guangzhou, GuangdongAges 18–75 - NCT04547725Recruiting
Surgery plus chemotherapy for stomach cancer in the belly lining
This study tests whether a thorough surgery to remove stomach cancer in the abdomen, followed by chemotherapy given through the belly and by vein, can improve outcomes. It’s for people newly diagnosed with stomach cancer that has limited spread to the belly lining.
TaipeiAges 20–75 - NCT04549688Recruiting
Active surveillance with focused ultrasound for prostate cancer
This trial studies whether a high-intensity focused ultrasound treatment can help people with localized prostate cancer while still avoiding traditional full-dose treatment for some patients. It may be an option for certain intermediate-risk cases where the cancer is confined to the prostate.
Tønsberg, VestfoldAges 18–80 - NCT04551378Recruiting
Study of how COVID affected young people with cancer
This study looks at how the COVID-19 pandemic affected the experiences of teenagers and young adults with cancer, including people who finished treatment. It may help improve support for cancer patients and survivors during public health crises.
Houston, TexasAges 18–39 - NCT04550845Recruiting
Study to teach genetics to men at risk for prostate cancer
This study aims to understand how men at higher risk for prostate cancer understand genetics terms, using an educational video. It may help improve patient education about genetic testing, especially for people who find these terms confusing.
