Filter by:Evaluation of the prognostic potential of tumor-infiltrating lymphocytes and PD-L1 expression in non-metastatic squamous cell carcinoma of the head and neck
Extranodal extension (ENE) refers to the spread of head and neck squamous cell carcinoma (HNSCC) outside the lymph nodes. It is a well-known factor that indicates a poorer prognosis and outcome for patients who have undergone surgical removal of the cancer. In such cases, it is recommended to combine chemotherapy with radiation therapy after surgery. As the number of cases of HNSCC related to the human papillomavirus (HPV) is increasing, treatment approaches have shifted towards using radiation therapy as the primary treatment method instead of surgery. This raises an important question about the significance of ENE observed through imaging tests (referred to as iENE) and its impact on the prognosis. Unfortunately, this question remains unanswered. The objective of this project is to conduct a comprehensive study across multiple medical institutions. The investigators will gather data including scan results, histopathology reports, and data from patient charts from individuals who have been treated for head and neck cancer. The aim is to analyze and correlate the findings between the pathological evidence of ENE and the imaging results, while also assessing the prognostic value of iENE. Additionally, the investigators will explore the influence of HPV status on these factors. By collecting and analyzing this data, the investigators hope to establish standardized criteria that can assist radiologists in accurately identifying ENE through imaging tests. This research is essential for enhancing our understanding of HNSCC and improving the effectiveness of diagnostic procedures and treatment planning.
To evaluate the efficacy and safety of Streptococcus salivarius K12 for prevention and treatment of oral mucositis in patients undergoing radiotherapy for malignant head and neck tumors.
Phase 1 study evaluating the safety and efficacy of BRG01 in subjects with relapsed/ metastatic EBV-positive nasopharyngeal carcinoma (NPC). BRG01 is a Chimeric Antigen Receptor T-Cell therapy targetting on the specific protein of EBV, which is expressed on the EBV associated cancer cells. This study adopts the traditional "3+3" dose escalation design. Approximately12~18 EBV+ NPC subjects will be enrolled to evaluate the safety of BRG01. An internal safety review team (SRT) will review the safety data and make recommendations on further study conduct and progression to subsequential cohorts. Subjects will be enrolled into 3 cohorts of different doses, designated as cohort A, B and C.Cohort A: 3.0x10^6 CAR-T cells/kg,3 subjects, Cohort B: 9.0x10^6 CAR-T cells/kg,3 subjects, and Cohort C:1.5x10^7 CAR-T cells /kg, 6 subjects,respectively. Subjects in each cohort will follow the same treatment schedule and procedural requirements.
The study is designed to evaluate the safety, tolerability, radiation dosimetry and pharmacokinetics 89Zr-TLX250 (also known as 89Zr-DFO-girentuximab) Positron Emission Tomography/Computed Tomography (PET/CT) in adult Chinese patients with indeterminate renal masses or Suspected Recurrent Renal Clear Cell Carcinoma
The purpose of this study is to learn about the effectiveness of the first and later lines of medicines on clinical outcomes in people with mRCC. The study includes participants who: - are 18 years old or above and have mRCC - took medicines that use the bodies immunity to fight against cancer as their first choice of treatment - took other medicines after taking the above first choice of treatment This is a study that looks into the data collected through a particular database from selected academic clinical sites participating in this study. The data of interest include: - the length of time between the start of a patient's treatment and the end of treatment - the length of time between the start of treatment and death - physician assessment of a patient's response to treatment We will compare the experiences of people receiving different combinations of treatments and see if there are any differences in the effectiveness of these medicines.
To readdress basal cell carcinoma (BCC) in the periocular region to prove histologically controlled surgical treatment efficacy and to identify high-risk characteristics.
The goal of this interventional clinical trial is to evaluate the dose of radiation of Technetium-99m macroaggregated-albumin (99mTc-MAA) after an intra-arterial injection to the whole body and non-liver critical organs in patients who are undergoing evaluation for SIR-Spheres treatment for hepatocellular carcinoma.
Adult patients suspected of Squamous Cell Carcinoma of Unknown Primary (SCCUP) will be prospectively enrolled at a tertiary head & neck cancer center at Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark. All patients will undergo Magnetic Resonance Imaging (MRI) and Positron Emission Tomography-Computerized Tomography (PET-CT) prior to examination in general anesthesia. During general anesthesia, Intraoperative Transoral Ultrasound (ITUS) will be performed prior to panendoscopy. Detected tumors will be registered with specified oropharyngeal sub-locations. Blinded to ITUS, a consultant head & neck surgeon will perform panendoscopy. After examination, the surgeon is unblinded to ultrasound results. Final histopathology results from location-specified biopsies performed will be used as reference standard. The overall detection rate will be compared between ITUS, panendoscopy, PET-CT and MRI with sensitivity and specificity analysis. Oropharynx sub-location specific detection rate of ITUS vs. panendoscopy will be compared with logistic regression analysis.
Radiotherapy is one of the main treatments for head and neck Carcinoma. The incidence of radiotherapy-related adverse events is greater than 90%, and severe adverse events may lead to the interruption of radiotherapy. Interruption of radiotherapy on the one hand affects the efficacy of tumor treatment, on the other hand seriously affects the quality of life of patients. Investigators intend to conduct a randomized, controlled clinical study of multidisciplinary nutritional and psychological care for patients receiving radiotherapy for head and neck carcinoma, with a view to reducing the rate of radiotherapy interruption and improving the quality of life of patients with radiotherapy for head and neck carcinoma through a whole-course multidisciplinary care model.
