Removing the main kidney tumor during immunotherapy for advanced kidney cancer
This trial tests whether removing or burning (ablating) the main kidney tumor helps people with advanced kidney cancer who are already doing well on immunotherapy. Researchers want to see if combining local treatment with ongoing immunotherapy can improve outcomes.
RomaAges 18 years+ - NCT06910449Recruiting
Radiation after lung lining surgery for spread cancer
This trial tests a type of radiation therapy (hemithoracic arc radiotherapy) for people whose cancer has spread beyond the lung and who have already had surgery to remove the lining of the lung. The goal is to see if this radiation helps control the disease.
Cairo, Fom ElkhaligAges 18 years+ - NCT06911684RecruitingPhase 2
Combination therapy before surgery for rectal cancer
This trial tests a combination of radiation, two immunotherapy drugs (iparomlimab and tuvonralimab), a targeted therapy (regorafenib), and chemotherapy (CAPOX) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can shrink the tumor and improve outcomes for people whose tumors have normal mismatch repair proteins (pMMR/MSS).
Guangzhou, GuangdongAges 18–75 - NCT06923345RecruitingPhase 2
Modified long-course radiation and chemo with immunotherapy for rectal cancer
This trial tests a treatment plan involving radiation, chemotherapy, and an immunotherapy drug (a PD-1 inhibitor) for people with a specific type of high-risk rectal cancer. The goal is to see if this combination helps shrink the tumor before surgery.
Guangzhou, GuangdongAges 18–75 - NCT06950073Recruiting
Second radiation treatment for lung cancer in the chest
This study tests whether giving a second course of radiation to the chest (called retreatment) can control lung cancer that has come back or a new cancer that started there. People who have already had radiation to their chest and are healthy enough for more may be eligible.
