Active clinical trials for "Carcinoma"

This phase II trial tests how well an imaging procedure called fludeoxyglucose F-18 (FDG) positron emission tomography/computed tomography (PET/CT) works in predicting response to standard of care chemotherapy prior to surgery in patients with HER2-positive stage IIa-IIIc breast cancer. FDG is a radioactive tracer that is given in a vein before PET/CT imaging and helps to identify areas of active cancer. PET and CT are imaging techniques that make detailed, computerized pictures of areas inside the body. The use of FDG-PET/CT may help doctors better decide if a patient needs more or less treatment before surgery in order to get the best response. This study evaluates whether FDG-PET/CT is useful in predicting a patient's response to standard of care chemotherapy.

Complete removal of cancer encircled by a secure margin of healthy tissue is the aim of surgical oncology. A close or positive surgical margin reported by pathologist typically ends in adjuvant therapies (re-surgery and/or radiotherapy), which come with prognostic risks and financial cost. Therefore, ex-vivo imaging of removed cancer tissue may assist in margin evaluation. In this study, investigators aimed to investigate the correlation of 3D ultrasound to histopathology to assess tongue tumor margin status.

Hypotheses: The addition of tumour bed boost after BCS in women with non-low risk DCIS reduces the risk of local recurrence (invasive or intraductal recurrence in the ipsilateral breast). The risk of local recurrence in the shorter fractionation arm is not worse than that for the standard fractionation arm. A molecular signature predictive of invasive recurrence of DCIS will be detectable and the molecular signature may eventually have clinical utility for therapy individualization. Overall Objectives: To improve the outcome of women with non-low risk DCIS treated with breast conserving therapy. To individualize treatment selection for women with DCIS to achieve long term disease control with minimal toxicity.

The goal of this single-arm prospective study is to evaluate the application of serum DNA methylation for HCC patients with normal alpha-fetoprotein. The main question it aims to answer is . Is the dynamic change of serum DNA methylation correlated to recurrence or treatment response of HCC

Rationale: In patients with medullary thyroid cancer (MTC), molecular imaging is used to assess the extent of disease in the primary diagnostic process and follow-up period to determine possible therapeutic options. The currently most used tracer in clinical practice, F-18 labelled fluorodeoxyglucose (18F-FDG), does not accurately detect MTC tumors with an indolent growth rate. A new, complimentary tracer is warranted to detect different subtypes. Objective: The primary objective is to assess the feasibility of using the F-18 labelled prostate specific membrane antigen (18F-PSMA) PET/CT for (re)staging patients with medullary thyroid cancer. The secondary objective is to compare the ability to detect MTC with the 18F-PSMA PET/CT to that of the 18F-FDG PET/CT. Study design: Prospective, single-centre, feasibility study. Study population: Patients (18 years of age or older) with biochemically and cytological/histological confirmed MTC, for whom the indication of an 18F-FDG PET/CT for tumor staging has already been determined on clinical grounds. Main study parameters/endpoints: The primary outcome of this study is the performance (lesion-based//patient-based sensitivity) of the 18F-PSMA PET to detect MTC lesions in patients with cytologically/histologically confirmed disease. Secondarily, the performance of the 18F-PSMA PET will be compared to the 18F-FDG PET/CT.

This is a study of pembrolizumab as consolidation therapy for a patient with small cell carcinoma of the ovary, hypercalcemic type (SCCOHT).

To evaluate the ability of [68Ga]N188 to detect nectin-4 overexpression in patients with urothelial carcinoma, especially in patients with recurrent or advanced bladder cancer.

This early phase I trial evaluates the use of hypoxia (lack of oxygen) as a measure in determining the outcome of Y90 selective internal radiation therapy in patients with liver cancer that has spread to a limited number of sites (oligometastatic). Radioembolization with Y90 is a minimally invasive procedure that combines embolization and radiation therapy to treat metastatic liver cancer. Tiny beads filled with radioactive isotope Y-90 are placed inside the blood vessel that provide blood supply to the tumor. This will block the blood flow to the tumor cells while providing a high radiation dose without harming healthy normal tissue.

This pilot clinical trial studies intensity-modulated accelerated partial breast irradiation (APBI) before surgery in treating older patients with estrogen receptor positive or progesterone receptor positive stage I breast cancer. APBI is a specialized type of radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

The purpose of this study is to see how useful the information provided from Positron Emission Tomography (PET) scans can be in the actual planning and delivery of radiation treatment to patients who have head and neck cancers. Patients participating in this study, will have (in addition to their routine tests) a PET scan before and during their radiation treatment. Following the intervention, patients will be followed as per standard practice.
