AngersAges 18 years+ - NCT06889545Recruiting
Comparing ways to measure frailty before surgery in older adults
This trial compares different ways to measure frailty in people aged 70+ before surgery lasting at least 2 hours, to see which tool works best.
HamburgAges 70 years+ - NCT06640881RecruitingPhase 2
Repeat breast-conserving surgery with partial reirradiation
This trial tests a new approach for women whose breast cancer has returned in the same breast after earlier surgery and radiation. Instead of removing the whole breast, doctors will remove only the tumor again and give a small, focused dose of radiation before surgery, aiming to preserve the breast.
AmsterdamAges 50 years+ - NCT05350722Recruiting
Single pre-surgery radiation for low-risk breast cancer
This trial tests a single, shorter course of radiation given before breast surgery for people with low-risk, hormone-receptor–positive breast cancer. It may help treat the breast tumor while reducing the number and length of radiation treatments.
SydneyAges 40 years+ - NCT03360838Recruiting
Prediction test for confusion after heart surgery in older adults
This study uses a short, self-answered thinking test before elective heart surgery to help predict who may develop confusion afterward. The goal is to improve early identification and care planning for patients at higher risk.
BaselAges 60 years+ - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT03516708RecruitingPhase 1/Phase 2
Epacadostat with pre-op radiation for locally advanced rectal cancer
This trial studies whether adding epacadostat (a cancer drug) to standard pre-operative chemoradiation can improve outcomes for people with locally advanced rectal cancer. It’s designed to see if the added treatment is safe and potentially more effective before surgery.
Orange, CaliforniaAges 18 years+ - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.
Guangzhou, GuangdongAges 18–75 - NCT03748485Recruiting
Chemo after surgery for certain stage III colon cancer
This trial studies whether adding chemotherapy after surgery helps people with colon cancer that was diagnosed before surgery as stage III and later found to be without certain high-risk features. It may help lower the chance the cancer comes back, but you must meet specific surgery and health criteria.
Guangzhou, GuangdongAges 18–75 - NCT03875781RecruitingPhase 3
Chemo before rectal surgery, without pelvic radiation
This Phase 3 study tests whether giving chemotherapy before rectal surgery can work as well as standard treatment that usually includes pelvic radiation. It aims to reduce the need for pelvic radiation while still keeping the cancer under control.
Le Kremlin-Bicêtre, Île-de-France RegionAges 18 years+ - NCT03926949Recruiting
Pre-surgery IV nutrition for malnourished adults
This trial tests giving nutrition through an IV before surgery to help adults who are malnourished. It may improve how you do around the time of the operation and support recovery.
Edmonton, AlbertaAges 18 years+ - NCT04031677RecruitingPhase 3
Surgery with or without chemotherapy for high-risk retroperitoneal sarcoma
This trial studies whether adding chemotherapy before surgery helps people with high-risk retroperitoneal (abdominal-area) leiomyosarcoma or liposarcoma. The goal is to improve outcomes while comparing surgery alone versus surgery plus neoadjuvant chemotherapy.
Birmingham, AlabamaAges 18 years+ - NCT04261244RecruitingPhase 3
Neoadjuvant radiation study for one-sided breast cancer
This Phase 3 study tests a specific plan that combines chemotherapy (and sometimes targeted medicines) with radiation before surgery for one breast. It may help shrink breast cancer and improve treatment timing, based on how well tumors respond.
AhausAges 18 years+ - NCT04288999RecruitingPhase 3
Surgery plus chemo versus chemo-radiation then surgery for recurrent rectal cancer
This study compares two treatment plans for locally recurrent rectal cancer: (1) surgery plus chemo, or (2) chemo plus radiation first, then surgery, followed by chemo. It aims to see which approach works better in controlling the cancer and helping patients recover.
ChibaAges 20–80 - NCT04427293RecruitingPhase 1
Testing lenvatinib and pembrolizumab before breast cancer surgery
This early-phase trial tests whether lenvatinib plus pembrolizumab given before surgery can help treat early-stage triple-negative breast cancer. If you qualify, you would receive study medicines before your planned operation to remove the tumor and nearby lymph nodes.
Chicago, IllinoisAges 18 years+ - NCT04493996Recruiting
Cognitive training before heart surgery to protect memory
This trial tests whether brain-focused cognitive training before elective heart surgery can help reduce memory and thinking problems afterward. If you qualify, you may do language-based thinking exercises and complete short brain tests around the time of surgery.
Bad NauheimAges 18 years+ - NCT04495088RecruitingPhase 3
Before vs after chemotherapy for locally advanced rectal cancer
This Phase 3 study compares giving chemotherapy before rectal surgery versus giving it after surgery, using a tailored plan based on your risk. The goal is to see which timing helps more people with locally advanced rectal cancer stay cancer-free and live longer.
MannheimAges 18 years+ - NCT04525989Recruiting
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+ - NCT04571736Recruiting
Web and video support during thyroid surgery planning
This study tests a pre-surgery video support program and a secure website to help people prepare for thyroid surgery. It may improve understanding and follow-through by collecting your answers before the operation.
