Comparing Radiation Therapy to Usual Care for Patients With High-Risk Bone Asymptomatic Metastases
NCT06745024
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

Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy
NCT04379570
Recruiting
This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treat... Read More

Gemcitabine and Cisplatin Without Cystectomy for Patients With Muscle Invasive Bladder Urothelial Cancer and Select Genetic Alterations
NCT03609216
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.

Olanzapine Versus Megestrol Acetate for the Treatment of Loss of Appetite Among Advanced Cancer Patients
NCT04939090
Recruiting
This phase III trial compares the effects of olanzapine versus megestrol acetate in treating loss of appetite in patients with cancer that has spread to other places in the body (advanced). Olanzapine may stimulate and increase appetite. This study aims to find out if olanzapine is better than the usual approach (megestrol acetate) for stimulating appetite and preventing weight loss.

Regional Radiotherapy in Biomarker Low-Risk Node Positive and T3N0 Breast Cancer
NCT03488693
Recruiting
The purpose of this study is to compare the effects on low risk breast cancer receiving usual care that includes regional radiation therapy, with receiving no regional radiation therapy. Researchers want to see if not giving this type of radiation treatment works as well at preventing breast cancer from coming back.
