The goal of this clinical trial is provide new treatment for patients with advanced melanoma who have failed previous immunotherapy. The main questions it aims to answer are: - Efficacy of PD1 monoclonal antibody combined with recombinant human adenovirus type 5 injection in patients with advanced malignant melanoma. - Safety of PD1 monoclonal antibody combined with recombinant human adenovirus type 5 injection in patients with advanced malignant melanoma.
The purpose of this research study is to test new ways to improve the usefulness of the world's first total-body positron emission tomography (PET)/computed tomography (CT) scanner (EXPLORER) by collecting data from PET scans using one of three different imaging agents: 18F-PSMA; 18F-FES; or, 68Ga DOTATATE. These imaging agents are approved by the FDA to be used for patients diagnosed with prostate cancer (18F-PSMA), neuroendocrine tumor (68Ga DOTATATE), or breast cancer (18F-FES).
The purpose of this study is to investigate the pathologic features, complications, and prognostic factors of functioning adrenal adenoma and suggest follow-up algorithms for adrenal incidentaloma.
Background: Sleep disturbances are among the most common and severe symptoms reported by people with primary brain tumors (PBT). Smart wearable devices like Fitbits may be able to give detailed data about people s sleep and circadian rhythms. In this study, researchers will use Fitbits to learn more about sleep disruptions caused by tumors. This might help them design better future treatment and supportive care studies. Objective: To describe sleep disturbances and circadian disruption in people with PBT. Eligibility: English-speaking adults ages 18 and older who have PBT and are enrolled in the NIH study, ...
This research is being done to determine if CEST Magnetic Resonance Imaging and F-dopa PET are feasible techniques to detect metabolic differences between tumor and brain.
This study will provide continuing availability to tazemetostat for people that have previously completed participation in a tazemetostat study, either with monotherapy (single drug treatment) or combination therapy. The aim of the study will be to assess the long-term safety of tezemetostat.
A retrospective crosssectional observational study of the effects of oncological treatment and frequent general anesthesia on neuropsychological development, psychosocial functioning (in terms of anxiety, depression, peer relations, perceived cognitive functioning and potential trauma) and health related quality of life in children and young adults who were treated or screened for retinoblastoma.
To determine the minimum scan duration for fluorine-18 positron-emitting radioactive isotope-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) scans performed on a total-body PET/CT scanner that results in non-inferior image quality to 18F-FDG PET/CT scans performed on a conventional PET/CT scanner. The subject population will be patients being staged for lung cancer, lymphoma, or melanoma.
This is a study to allow continued treatment for participants enrolled in studies of BXQ-350. This study is intended only for those who have completed the required study observation period or are still on treatment upon the closure of their respective BXQ-350 clinical study. The additional treatment is optional and voluntary.
This research aims to explore the relationship between hormonal receptor expression and the clinical and histopathological characteristics of meningiomas. The underlying hypothesis is that hormonal receptor expression, as well as the methylation profile of their gene promoters, are associated with specific aspects of meningiomas and patients' clinical outcomes. The main objective is to study the correlation between the immunohistochemical expression of hormonal receptors and clinicopathological data. The secondary objectif is to study the correlation between the methylation profile of hormonal receptor gene promoters and their...
