Carboplatin Chemotherapy Before Surgery for People With High-Risk Prostate Cancer and an Inherited BRCA1 or BRCA2 Gene Mutation
Recruiting
This phase II trial tests how well carboplatin before surgery works in treating patients with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene mutation. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping, or slowing the growth of tumor cells. Giving carboplatin before surgery may shrink tumors in patients with h... Read More

Ramucirumab and Paclitaxel or FOLFIRI in Advanced Small Bowel Cancers
Recruiting
This phase II trial studies how well ramucirumab and paclitaxel or the FOLFIRI regimen (leucovorin calcium, fluorouracil, and irinotecan hydrochloride) work in treating patients with small bowel cancers that have spread extensively to other anatomic sites (advanced) or are no longer responding to treatment (refractory). Ramucirumab is a monoclonal antibody that attaches to and inhibits a molecule called VEGFR-2. This may restrain new blood vessel formation therefore reducing nutrient supply to t... Read More

Comparing Radiation Therapy to Usual Care for Patients With High-Risk Bone Asymptomatic Metastases
Recruiting
This phase III trial compares the effect of adding radiation therapy to usual care on the occurrence of bone-related complications in cancer patients with high-risk bone metastases that are not causing symptoms (asymptomatic). High-risk bone metastases are defined by their location (including hip, shoulder, long bones, and certain levels of the spine), or size (2 cm or larger). These bone metastases appear to be at higher risk of complications such as fracture, spinal cord compression, and/or pa... Read More

Comparing Impact of Treatment Before or After Surgery in Patients With Stage II-IIIB Resectable Non-small Cell Lung Cancer
Recruiting
This phase III trial compares standard therapy given after surgery (adjuvant) to standard therapy given before and after surgery (perioperative) in treating patients with stage II-IIIB non-small cell lung cancer (NSCLC) that can be removed by surgery (resectable). The usual approach for patients with resectable NSCLC is chemotherapy and/or immunotherapy before surgery, after surgery, or both before and after surgery. This study is being done to find out which approach is better at treating patie... Read More

Genetic Testing in Guiding Treatment for Patients With Brain Metastases
Recruiting
This phase II trial studies how well genetic testing works in guiding treatment for patients with solid tumors that have spread to the brain. Several genes have been found to be altered or mutated in brain metastases such as NTRK, ROS1, CDK, PI3K, or KRAS G12C. Medications that target these genes such as abemaciclib, paxalisib, entrectinib and adagrasib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Genetic testing may help doctors tailor treatment for... Read More

Gemcitabine and Cisplatin Without Cystectomy for Patients With Muscle Invasive Bladder Urothelial Cancer and Select Genetic Alterations
Recruiting
This phase II trial studies how well gemcitabine hydrochloride and cisplatin work in treating participants with invasive bladder urothelial cancer. Drugs used in chemotherapy, such as gemcitabine hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
