Filter by:Study Purpose: A multicenter prospective study to evaluate the outcome of second breast cancer surveillance with abbreviated breast MR (AB-MR) or ultrasound (US) in addition to annual mammography in women with BRCA1/2 mutation testing Study Scheme: - AB-MR, US, and digital mammography will be performed on the same day and interpreted independently at baseline and then after 1 year. - After completion of study, patients are followed-up for at least 1 year.
The purpose of this prospective, parallel-group, cohort study is to implement phenotype-guided targeted therapy based on functional signal transduction pathway (STP) activity in recurrent ovarian cancer patients using a novel mRNA-based assay. Existing targeted drugs with tolerable toxicity profiles are used to investigate the therapeutic value beyond their approved indication, which are deemed beneficial in the select group of patients with a relevant predominantly active functional STP, in order to improve survival and maintain quality of life.
Brain metastases are the most common intracranial tumors in adults. Whole-brain radiation therapy (WBI) increases the median survival of patients with brain metastases up to 3-6 months, but WBI can lead to the decline of cognition and quality of life, with short local control time. The use of SIB(simultaneous integrated boost) technology can increase the local control rate. Hippocampus avoidance can effectively reduce the cognitive impairment caused by WBI.This study was designed to evaluate the safety and efficacy of selective brain radiotherapy (EBI)(based on SIB and hippocampus, inner ear avoidance )in NSCLCs with limited brain metastases.
This randomized, open label study will evaluate a nurse and pharmacist led clinic conducted remotely from Grand River Regional Cancer Centre at Grand River Hospital (GRRCC/GRH) using OTN teleconferencing as a platform for patients with prostate cancer receiving oral chemotherapy agents.
This is a multicenter prospective controlled trial of percutaneous laser ablation(PLA) versus conventional surgery for the treatment of papillary thyroid microcarcinoma (PTMC).
The purpose of this study is to identify potential risk factors for and determine the rate of pathological fracture for patients which having spine metastases from breast cancer and be defined as potentially unstable (SINS 7-12) according to the Spinal Instability Neoplastic Score (SINS). The investigators' analysis will provide robust data about the development of spinal instability and help identify the optimal timing of local surgery treatment.
The purpose of this study is to learn whether our own made predictive algorithm can be used as a clinical practical decision support for patients with NSCLC spinal metastasis. The scoring system consists of the use of EGFR-TKI, KPS, Age, SCC, CA125 and smoking history. By predicting survival doctors could determine which patients are suitable for palliative therapy.
INTRAMET examines prospectively the effectiveness of an intraoperative radiotherapy immediate after the surgical resection of brain metastases. Patients won't receive further radiation therapy of the intraoperatively treated lesion.
Cisplatin, anthracyclines, bleomycin and trastuzumab can cause severe cardiovascular or pulmonary toxicity. Why some patients are susceptible to extreme toxicity of cancer treatment is largely unknown. Unraveling extreme cardiovascular toxic responses in cancer patients may help understand the pathophysiology of cardiovascular toxicity of these agents and help in understanding the more subtle, long-term cardiovascular side effects that affect a larger part of cancer survivors. With induced pluripotent stem cells we will obtain patient-derived cells to recapitulate and mimic and study pathological (cardiovascular) responses and (cardiovascular) toxicity in vitro.
The primary objective is to prove non-inferiority of thermal ablation compared to hepatic resection in patients with at least one resectable and ablatable colorectal liver metastases (≤3cm) and no extrahepatic disease.
