This is a non-controlled, open label, Phase II Study of ipilimumab combined with a Stereotactic Radiosurgery. The study included an induction phase of four IV infusions of Ipilimumab at 10 mg/kg every 3 weeks associated with a stereotactic radiosurgery performed 3 days before 2nd ipilimumab administration. A Maintenance phase included Ipilimumab, IV, 10 mg/kg once every 12 weeks, starting at week 24, in the absence of PD, unacceptable toxicity or withdrawal of consent or disease progression. The primary objective is the overall survival. The Secondary objectives include safety, ORR, PFS and peripheral blood absolute lymphocyte count (ALC) as a predictive biomarker.
The purpose of this study is to determine the safety of adoptive transferring autologous IKDC-like cells
This clinical trial was designed to investigate the efficiency and toxicity of fractionated stereotactic radiotherapy(FSRT) combined with Temozolomide(TMZ) for refractory brain metastases.
The purpose of this study is to see if capecitabine can be taken safely with different doses of lapatinib in patients with HER-2 positive breast cancer involving brain (brain metastases) and/or in spinal fluid (leptomeningeal disease).
With rapid advances in molecular oncology, the availability of preclinical in vitro cell models and in vivo animal models with specific genomic aberrations is critical for improved prediction of clinical outcomes in cancer patients. One of the most widely used preclinical models is conventional cell lines, such as the NCI-60 panel of cell lines;these cell lines are widely used in preclinical testing for novel targeted drugs, partially owing to the low expense and reduced labor associated with cell culture compared with other preclinical models, such as animal xenografts. However, recent studies have shown that accumulation of genetic aberrations in cancer cell lines occurs with increasing passage number. These models also lack the heterogeneity of tumors and do not exhibit a proper microenvironment, highlighting the limitations of cell-based models. Consistent with this, Johnson et al. demonstrated that in vivo activities of the cell lines within the NCI-60 panel did not closely correlate with corresponding human cancers. Therefore, to better preserve the genomic integrity and tumor heterogeneity observed in patients, patient-derived xenograft (PDX) models are being used more frequently. PDX is generated by directly transplanting freshly resected patient tumors into immunocompromised murine hosts with or without an intermediate in vitro culture step. This PDX model is an improvement over cell lines because it can provide both an appropriate tumor microenvironment and heterogeneity of tumor cells. However, the engraftment success rates and growth rates of implanted tumors are highly variable depending on the tumor type, possibly due to insufficient numbers of hematopoietic cells and/or ineffective microenvironmental cues in the mouse stroma. The extent to which tumor cells from freshly resected tumors are able to withstand mechanical stresses and xenotransplantation barriers is also unclear. Furthermore, the use of PDX models for application in clinical oncology is limited owing to the time required for PDX establishment (> 4 months) since most patients with refractory cancer live less than 1 year. Recently, PDC line models have been suggested as an alternative preclinical model to be used as a prediction tool for preclinical drug sensitivity. Therefore, in this study, the investigators aimed to overcome these potential barriers of pre-existing models by examining the capacity of PDC line models to recapitulate the histological and genomic features of primary patient tumors. In selected cases, the investigators screened drug sensitivity in vitro using PDC lines and compared the results with real-life clinical treatment outcomes.
The purpose of this study is to evaluate the safety and effectiveness of robot-assisted simultaneous resection in selected patients with sigmoid colon cancer or rectal cancer liver metastases, and compared with the traditional open procedure.
This study aims to prove that a strategy of first line local ablation of colorectal liver metastases with microwaves is not inferior to liver resections in terms of survival rates at three years with secondary endpoints being survival at five and ten years, interventional complication rates, length of stay, ablation precision measurements, need for further interventions and health-economic analysis. A cohort of 100 patients treated with CT guided microwave ablation of 1-5 metastases <31mm in size will be followed and compared with propensity scored matched controls from the Swedish liver surgery registry - Sweliv. The study is a multi-institutional effort by the Hepato Pancreatico Biliary (HPB) units in Stockholm Sweden, Bern Switzerland and Groningen in the Netherlands.
The purpose of this multicenter study is to assess a diagnostic strategy concerning differential diagnosis between radiation necrosis and relapse in brain metastases treated with radiosurgery. Two non-invasive tests - positron emission tomography (PET) with 1F-fluoro-ethyl-tyrosine (FET) and magnetic resonance spectroscopy (MRS) - will be compared to histology in a cohort of patients presenting growing lesions 6 months after radiosurgical treatment. The results of this study should help to earlier diagnosis of recurrences after radiosurgery and to perform an appropriate treatment for patients.
The main purpose of this 3-part study is to evaluate the safety and efficacy of the study drug known as LY2880070 in participants with advanced or metastatic solid tumors.
