This phase 2 trial tested adding the immunotherapy drug durvalumab to a standard chemotherapy regimen (docetaxel, oxaliplatin, S-1) before and after surgery in 68 patients with resectable stomach or gastroesophageal junction cancer. The main goal was to see how many patients had …

This phase II study tested whether adding trastuzumab (a targeted therapy) to standard chemotherapy could help people with advanced stomach or gastroesophageal junction cancer. Unlike typical patients, these participants had tumors that tested negative for HER2 in tissue but posi…

This phase II trial tested the chemotherapy drug paclitaxel in 40 patients with advanced or metastatic gastrointestinal stromal tumor (GIST) whose cancer had stopped responding to three standard treatments: imatinib, sunitinib, and regorafenib. The study focused on patients with …

This study tested whether using intravascular ultrasound (a tiny camera inside the artery) to guide stent placement in the leg is better than the usual X-ray guidance. One hundred people with blocked leg arteries were randomly assigned to one of the two methods. The goal was to s…

This study looked at how effective and safe niraparib is for Korean women with epithelial ovarian cancer. It included 850 patients who took niraparib as maintenance therapy or as a later treatment. Researchers measured how long patients lived without their cancer getting worse an…

This study tested whether aflibercept injections into the eye can improve areas of poor blood flow in the retina of people with diabetic retinopathy. 38 adults with nonproliferative diabetic retinopathy received the treatment. The goal was to see if the drug could reduce the risk…

This study tested a new way to deliver chemo directly to liver tumors using a wrist artery instead of the groin. Thirty-eight patients with liver cancer took part. The goal was to see if the wrist approach is safe, feasible, and effective, with fewer complications and faster reco…

This study tested a wearable heart monitor called Cardea SOLO against a standard 12-lead EKG to see if it could better detect paroxysmal atrial fibrillation (a temporary irregular heartbeat) in people who had a stroke of unknown cause and have an enlarged heart. 257 participants …

This study tests whether a special PET scan using a radioactive tracer called FES can accurately detect breast cancer that has spread to lymph nodes under the arm. Researchers will scan 71 people with estrogen-positive breast cancer and compare the results to standard methods. If…

This study tested whether giving the antibiotic cefoxitin using a target-controlled infusion pump works better than the standard method to prevent surgical site infections in patients having colon or rectal surgery. About 2,500 adults took part. The goal was to see if the new met…

This study tested whether using a motion-tracking exergame (Nintendo Ring Fit) in bed is safe and doable for patients who cannot walk. 26 adults who were bedridden after organ transplants or critical care played personalized exercise games for 30 minutes daily over two weeks, sup…

This study tested whether a rehabilitation program using a smartphone app (MORA) could help bedridden hospital patients improve their physical function. Twenty-five adults who could not walk used the app to do personalized exercises twice daily for two weeks. The goal was to see …

This study tested whether a mobile app that lets cancer patients report their symptoms to their doctor can reduce unplanned hospital visits. 166 adults with solid cancers on systemic therapy participated. Half used the app before clinic visits, while the other half had usual care…

This study uses ultrasound to measure the distance between the subclavian vein and nearby risky structures like the lung and artery. Researchers will compare two ultrasound probe positions (above vs below the collarbone) and check if arm position changes the safety margins. About…

This study looked back at the records of nearly 7,000 adults who had a liver transplant to see if taking statins beforehand lowered their risk of major heart problems. Researchers checked for events like heart attack, stroke, and heart failure within 30 days after surgery. The go…

This study looked back at the medical records of 90 adults with neck and arm pain caused by a pinched nerve. Researchers wanted to see if MRI scans could predict who would get good pain relief from a procedure called a stellate ganglion block, where numbing medicine is injected n…

This study looked at whether a patient's abdominal circumference (belly size) is linked to how long surgery takes to remove a pheochromocytoma, a rare adrenal tumor. Researchers reviewed records of 159 adults who had the surgery. The goal was to see if belly size could help docto…

Researchers analyzed data from over 640,000 adults who had non-cardiac surgery to create a model that predicts the chance of dying within 30 days, 180 days, and one year after surgery. The model uses information from hospital records and national death registries. This study is c…

This completed study looked at 98 adults with acute myeloid leukemia (AML) in first remission who received a stem cell transplant from a matched sibling, matched unrelated, or half-matched family donor. All patients got the same chemotherapy conditioning before transplant. Resear…

This completed study involved 146 patients with blood cancers who received a stem cell transplant from a donor. Researchers collected blood and tissue samples over a year to study immune cells linked to graft-versus-host disease (GVHD), a common complication where donor cells att…
