Malignant Neoplasms

CONSTELAR is a prospective, single-arm, multi-specialty registry designed to evaluate the safety and intraoperative performance of the RonovoTM robotic surgical platform in adult patients undergoing elective oncological surgery. The study enrolls patients across four surgical specialties (Digestive Surgery, Thoracic Surgery, Urology, and Gynecology) at a single academic center. Primary endpoints include 30-day and 90-day complication rates (Clavien-Dindo classification), operative times, conversion rates, estimated blood loss, and device-related technical failures. Secondary endpoints encompass length of hospital stay, Intensive Care Unit (ICU) admission, readmission/reoperation rates, and oncological surgical outcomes (resection margins, lymph node harvest). The study aims to provide initial safety and feasibility data to support the regulatory pathway for the RonovoTM platform in Latin America.

The goal of this first in human, Phase 1, multi-center, open-label, and 2-part study is to learn whether DEG6498 is safe and tolerable in participants with advanced solid tumors. It will also learn about DEG6498 pharmacokinetics (PK) profile and potential antitumor activity. The main questions it aims to answer are: * what is an appropriate dose to be given to participants? * are the side effects of treatment manageable? Participants who are treated in this study will receive DEG6498 orally once a day and be closely monitored by the treating physicians.

The purpose of this clinical trial is to learn the safety and effects of the study medicine (PF-07799544) alone or in combination as a potential cancer treatment for adults with advanced solid tumors. The study will be conducted in two parts: PF-07799544 as a single agent (Phase 1a) and PF-07799544 in combination with another study medicine called PF-07799933 (Phase 1b). Phase 1a is no longer open for enrollment. In Phase1b (noted as "this study"), we are seeking participants who have: * a solid tumor which is metastatic or recurrent (excluding colorectal cancer) * tumor with the mutation (abnormal gene) called "BRAF V600" * received required prior treatment for cancer per cohort assigned. All participants in this study will receive both study medicines. Both study medicines are tablets that are taken by mouth at home twice a day. Participants will receive study medicines until their cancer is no longer responding, unacceptable side effects, or 2 years. Participants may continue to receive study therapy beyond 2 years. We will examine the experiences of people receiving the study medicines. This will help us determine if the study medicines are safe and effective.

This single-center prospective cohort study investigates the association between body composition parameters and setup errors in 120-150 patients receiving radiotherapy with thermoplastic mask immobilization. Body composition (skeletal muscle mass, body fat percentage, phase angle, fat-free mass) will be measured using bioelectrical impedance analysis at baseline and at fraction 20. Setup errors (six degrees of freedom) will be recorded via daily cone-beam computed tomography. The primary outcome is the association between baseline body composition and setup errors. Secondary outcomes include the relationship between body composition changes during radiotherapy and setup error evolution, and identification of threshold values for clinically significant setup error increases. This study will provide evidence on whether body composition-beyond BMI-predicts radiotherapy setup accuracy, potentially enabling personalized immobilization and image-guided strategies.

Selected individuals suspected of having or with prior biopsy proof of malignant disease will be seen in the Urologic Oncology Branch, NCI. Blood samples may be collected at the time of the initial visit and at periodic intervals during the course of the disease. These samples will be stored in the tissue bank of the Urologic Oncology Branch. Aliquots of malignant and normal tissue will be collected at the time of surgery and stored in the tissue bank, Urologic Oncology Branch, NCI. These materials will be used in the research efforts of the Urologic Oncology Branch, NCI....

The purpose of this research is to understand how radiotherapy and other cancer treatments impact sexual function in female cancer patients and to try to answer a question about why some patients who receive radiotherapy are more likely to have side effects than others. The results of this study may improve our understanding of why sexual side effects occur and in turn develop predictive models and biomarkers of sexual side effects and other side effects that may impact sexual function. The results of this study may also lead to improvements in the techniques used to deliver radiotherapy or the development of interventions that will prevent or reduce sexual side effects and improve quality of life for female patients with cancer.

Phase I study of YKYY031 for injection in patients with advanced solid tumors

"This study is a phase 2, randomized study to evaluate the efficacy and safety of SLC-3010 in combination with axitinib versus axitinib monotherapy as second-line treatment in patients with locally advanced or metastatic clear cell renal cell carcinoma (ccRCC). This study includes a screening period, a treatment period, and a follow-up period. All patients will complete a screening period of up to 28 days. During the treatment period, patients will receive either SLC-3010 in combination with axitinib or axitinib monotherapy. Treatment may continue until the occurrence of unacceptable toxicity related to the study intervention, patient refusal for further participation, or disease progression. The patients will be followed up for disease progression and survival for up to 2 years after discontinuation of the study intervention, or until death, consent withdrawal, or the end of this clinical trial, whichever occurs first. For patients who withdraw consent, survival will be followed up via telephone or site visits every 2 months up to death or 12 months after the first administration of the last patient, whichever occurs first, depending on their consent for follow-up. This study consists of two parts: Part 1 is the safety run-in phase for SLC-3010 in combination with axitinib, and Part 2 is a randomized phase 2 trial to compare SLC-3010 in combination with axitinib and axitinib monotherapy.
