This study aims to use the new molecular probe 18F-PSMA for the diagnosis,staging ,recurrence monitoring and evaluation of the prostate cancer.By compared with the conventional imaging methods (whole body bone scintigraphy and MRI) and molecular imaging methods (11C-choline PET/CT),we hope to find the advantages of 18F-PSMA PET/CT in the diagnosis and metastases of prostate cancer, and lay the foundation for the further clinical transformation.
For now, neoadjuvant chemoradiotherapy is routinely performed for T3N1-2M0 rectal cancer. However, there are lots of complications following neoadjuvant chemoradiotherapy, such as Wound-related complications, anastomotic leakage, anastomotic stenosis, sexual dysfunction, testicular or ovary failure. Patients undergoing resection for rectal cancer had low rates of local recurrence and long disease-free survival regardless of whether an APR, CAA or low AR was performed. The main purpose of preoperative radiotherapy is to lower the local recurrence. For the T3N1-2M0 rectal cancer with negative circumferential resection margin based on MRI assessment, we suppose might not necessary to receive neoadjuvant chemoradiotherapy, for operation can achieve the negative circumferential resection margin.
ERCP with brush cytology has a poor to moderate accuracy in unclear biliary lesions. Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) for cytology may override some of these shortcomings. The current prospective study, performed in a tertiary University center, aims to study the feasibility, the accuracy and the clinical value of combinatory ERCP and EUS in unclear biliary lesions.
This is a multicentre, non-randomized, open-label, Phase I/II clinical trial of MDG1011, an investigational medicinal product (IMP), consisting of patient-derived autologous T cells, persistently transduced with a Preferentially Expressed Antigen in Melanoma (PRAME)-specific human leukocyte antigen (HLA)-A*02:01-restricted T cell receptor (TCR).
This phase Ib trial studies the side effects and best dose of copanlisib and nivolumab and side effects of copanlisib given together with nivolumab and ipilimumab in treating patients with solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or lymphoma. Copanlisib stops tumors from growing by blocking proteins that are known to be important for tumor cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving copanlisib together with nivolumab or with nivolumab and ipilimumab may work better in treating patients with solid tumors or lymphoma.
Breast cancer is the most prevalent cancer affecting women. To treat locally advanced breast cancers, neoadjuvant chemotherapy (NACT) is often carried out before surgery to reduce the tumour size to allow breast conservation surgery. However, treatment response for individual patients varies, where the tumour may not respond to treatment and the quality of patient care is compromised if the NACT treatment plan is not optimised. Therefore, the assessment of NACT efficacy is beneficial for the early identification of these patients and appropriate management of treatment. Breast tumours have unique features compared to healthy tissue, including abnormal tissue structure and biochemical composition. With NACT there are specific changes to such tumour features indicating tumour treatment response. The purpose of this study is to establish how the changes to breast tumour features following NACT treatment are seen in non-invasive imaging. This study will look at scans of breast tumours using magnetic resonance imaging (MRI). Changes to tissue structure will be measured by advanced diffusion MRI techniques and changes to tumour related biochemical substances will be measured by advanced magnetic resonance spectroscopy techniques. The investigators aim to assess if these techniques can provide information on the tumour treatment response following subsequent rounds of NACT treatment. In this longitudinal study, 25 patients undergoing NACT will be recruited for four repeated MRI investigations over the course of NACT treatment. Magnetic resonance (MR) measurements of tissue microstructure and biochemical composition will be compared against histological measurements and radiological assessments of treatment response. The study will recruit patients undergoing treatment at the NHS Grampian. This research is funded by Friends of ANCHOR, Tenovus Scotland Grampian and the NHS Grampian Endowment Research Fund.
This is a Phase 1 study of central nervous system (CNS) locoregional adoptive therapy with autologous CD4 and CD8 T cells lentivirally transduced to express a HER2-specific chimeric antigen receptor (CAR) and EGFRt, delivered by an indwelling catheter in the tumor resection cavity or ventricular system in children and young adults with recurrent or refractory HER2-positive CNS tumors. A child or young adult with a refractory or recurrent CNS tumor will have their tumor tested for HER2 expression by immunohistochemistry (IHC) at their home institution or at Seattle Children's Hospital. If the tumor is HER2 positive and the patient meets all other eligibility criteria, including having a CNS catheter placed into the tumor resection cavity or into their ventricular system, and meets none of the exclusion criteria, then they can be apheresed, meaning T cells will be collected. The T cells will then be bioengineered into a second-generation CAR T cell that targets HER2-expressing tumor cells. The patient's newly engineered T cells will then be administered via the indwelling CNS catheter for two courses. In the first course they will receive a weekly dose of CAR T cells for three weeks, followed by a week off, an examination period, and then another course of weekly doses for three weeks. Following the two courses, patient's will undergo a series of studies including MRI to evaluate the effect of the CAR T cells and may have the opportunity to continue receiving additional courses of CAR T cells if the patient has not had adverse effects and if more of their T cells are available. The hypothesis is that an adequate amount of HER2-specific CAR T cells can be manufactured to complete two courses of treatment with three doses given on a weekly schedule followed by one week off in each course. The other hypothesis is that HER-specific CAR T cells safely can be administered through an indwelling CNS catheter to allow the T cells to directly interact with the tumor cells for each patient enrolled on the study safely can be delivered directly into the brain via indwelling catheter. Secondary aims of the study will include to evaluate CAR T cell distribution with the cerebrospinal fluid (CSF), the extent to which CAR T cells egress or traffic into the peripheral circulation or blood stream, and, if tissues samples from multiple time points are available, also evaluate the degree of HER2 expression at diagnosis versus at recurrence.
This is a Phase 1 open-label, dose-escalation, safety and pharmacokinetic study of rucaparib administered twice daily (BID) to Japanese patients with a solid tumor who have failed previous standard treatment for their cancer. A recommended dose of rucaparib for Japanese patients will be determined in a dose-escalation portion and then further evaluated in a dose-expansion portion of the study.
Endometrial cancer is the most common malignant tumor of the female genital tract in our means. The diagnosis is made by endometrial biopsy sampling with anatomopathological analysis which pinpoints the cell line and the level of cell differentiation. Its treatment is surgical with adjuvant treatment (chemotherapy or radiotherapy) besides, depending on the staging. Thus far, in the first diagnosis it is only request the tumor marker CA125 in serum, but there are studies that identify the HE4 protein in blood as a feasible marker for endometrial cancer. Furthermore, the staging changes the surgical and the adjuvant treatment: in its early stages, surgery is based on hysterectomy and double adnexectomy, however, in later stages it is necessary to add pelvic and paraaortic lymphadenectomy with the associated comorbidity. This makes extremely important that the preoperative diagnosis is accurate. The aim of this study is to identify and characterize the HE4, Ki67, p53 and other potential biomarkers in endometrial tissue in order to diagnose patients with disease only with a biopsy. Moreover, the investigators are searching for connections among these markers and prognostic factors such as grade of cell differentiation, cell line, lymphatic affectation, tumor stage or even features as survival or disease free survival.
