Active clinical trials for "Carcinoma"

The Exalenz clinical investigation is a multicenter, non-randomized, study of the ¹³C-Octanoate Breath Test (OBT). The present study is a feasibility trial, which aims to evaluate the capability of the OBT measurement to differentiate between presence and absence of HCC determined by Magnetic Resonance Imaging (MRI) in patients with chronic liver disease.

This research study is studying biomarkers in tissue samples from patients with stage III, stage IV, or recurrent endometrial cancer. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.

The purpose of this study is to determine the feasibility and toxicity of combining SBRT and TACE for unresectable HCC and to evaluate the Health Related Quality of Life (HRQL) associated with combined therapy.

The investigators will first use our previously collected serum samples and surgical/biopsied tissues from HBV-related HCC patients undergoing radiotherapy. The consistency of junctional clones by Capture NGS needs to be tested between both pre- and post-RT serums, and serial changes in copy numbers of vh-DNA by ddPCR are quantified in the representative cases. The same junction clones from pre-post-RT serums and surgical tissues will be confirmed and the copy number changes of vh-DNA be correlated with RT response and disease-control status. The investigators plan to identify HBV integrations by Capture NGS and quantify the specific vh-DNA by ddPCR as personalized biomarkers from the same-patient serum samples. The investigators will further correlate clinical response and recurrence/metastasis with serial changes of vh-DNA copy numbers. The investigators have been prospectively collecting plasma samples from HBV-related HCC patients before/after RT, at 1, 4, 7 months, and at recurrence/metastasis. The investigators plan to confirm the viable role of pre-/post-RT changes of plasma vh-DNA copies of the same junction clone in post-RT response and prognosis. Moreover, The investigators will explore the recurrent/metastatic tumors arising from the original or a de novo one by identifying their clonality with HBV integration patterns. The true value of this novel HBV chimera vh-DNA will be revealed. The results will also support the consolidative use of personalized vh-DNA for earlier evaluating treatment response after RT, for post-RT disease monitoring, and for differentiating clonality at recurrence to design future clinical trial on combinational treatment.

Clinical trials can sometimes favor certain demographic groups. Additionally, there is limited research that delves into the factors that influence participation in clinical study, both positive and negative. The goal is to identify the obstacles and challenges that prevent participation in hepatocellular carcinoma clinical research, as well as the reasons for withdrawal or discontinuation. Insights gained from this study will ultimately benefit those with hepatocellular carcinoma who may be invited to participate in clinical research in the years to come.

In this prospective cohort study, investigators will conduct ultrasound surveillance of the nodal basins of patients with head and neck cutaneous squamous cell carcinoma (cSCC) whose tumors are considered high risk and staged by the Brigham and Women's Hospital (BWH) tumor staging system. The study will enroll patients with tumors staged T2a and who are also immunosuppressed (from solid organ transplant, hematologic malignancy or autoimmune disease), T2b (sentinel lymph node negative), and T3 (sentinel lymph node negative). After two years of surveillance, outcomes regarding local recurrence, nodal metastasis, disease specific death, and overall survival will be compared with historical controls with the overall hypothesis that ultrasound surveillance will detect subclinical disease earlier and help improve outcomes.

This phase IV trial studies how well an investigational scan (18F-fluciclovine PET-CT) works for the measurement of therapeutic response in patients with prostate cancer that has spread to other places in the body (metastatic). 18F-fluciclovine is a radioactive substance that is used in this study with PET-CT imaging scans that may help doctors learn about response to standard therapy in patients with prostate cancer.

An observational study of Cxbladder performance for detection or rule-out of upper tract urothelial cancer. Subjects will be prospectively recruited to a single arm observational study to validate the performance characteristics of Cxbladder for suspected (UTUC) or for patients with a history of UTUC and are under surveillance for recurrence of disease.

To compare the prognosis and adverse reactions of unresectable hepatocellular carcinoma receiving stereotactic radiotherapy combined with hepatic arterial chemoembolization and conversion hepatectomy

This observational cohort study was aimed to evaluate the hearing toxicity at multiple time points from baseline to 1 year after radical chemoradiotherapy among nasopharyngeal carcinoma patients.
