Filter by:The purpose of this study is to evaluate whether HIFU-assisted liver resection (HIFU-AR) results in reduced blood loss compared to standard liver resection in patients with LM.This is a prospective, monocentric, randomized (1:1 ratio), comparative, open-label Phase II study.
This phase I pilot trial studies the side effects of stereotactic radiosurgery and nivolumab in treating patients with newly diagnosed melanoma that has spread to the brain or spine. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor to more precisely target the cancer. Monoclonal antibodies, such as nivolumab may interfere with the ability of tumor cells to grow and spread. Giving stereotactic radiosurgery together with nivolumab may be a better treatment for melanoma.
This phase II clinical trial studies how well thermal ablation and spine stereotactic radiosurgery work in treating patients with cancer that has spread to the spine (spine metastases) and is at risk for compressing the spinal cord. Thermal ablation uses a laser to heat tumor tissue and helps to shrink the tumor by destroying tumor cells. Stereotactic radiosurgery delivers a large dose of radiation in a short time precisely to the tumor, sparing healthy surrounding tissue. Combining thermal ablation with stereotactic radiosurgery may be a better way to control cancer that has spread to the spine and is at risk for compressing the spinal cord.
This study aims at estimating the incidence of second primary malignancies as well as the overall survival among metastasized prostate cancer (mPC) and metastasized castrate-resistant prostate cancer (mCRPC) patients not treated with radium-223-dichloride.
Conventional vertebroplasty is an effective option in the treatment of bone lesions (osteoporotic and neoplastic). It is indicated as an analgesic treatment and aims at reinforcing a compressed vertebrae or at risk of fracture. The main adverse event related to vertebroplasty use is the cement leakages that might be responsible for significant clinical impairments. Kyphoplasty is a recent alternative strategy of vertebroplasty, based on the insertion on balloon through the needle into the targeted vertebrae and then inflation of the balloon prior to cement injection into the space. In an osteoporotic setting, kyphoplasty allow reducing the incidence of cement leakage. To date, no data from randomized study are available in the population of cancer patients.
RECIST criteria for evaluating tumor response are often inadequate for the evaluation of anti-angiogenic drugs. An evaluation model of tumor perfusion with contrast-enhanced ultrasonography was developed at Gustave Roussy. It assesses the tumor vascular response through the analysis of 7 different parameters. Several studies (four at IGR, involving 117 patients, and a multicenter study involving 400 patients) showed that CEUS allows early evaluation of the effect of anti-angiogenic drugs. Two of these parameters are particularly interesting for the early identification of patients responding (or not) to treatment. Those are area under curve , and area under the wash-out. To further validate the use of these parameters, it is essential to measure and describe the level of their intra-patient variability.
Monitoring of circulating endothelial cells (CEC and mature cells called progenitors called CEP) or circulating tumor cells (CTC) in adult patients with metastatic cancer, possibly treated with targeted therapy.
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 evaluate the efficacy of spinal analgesia for minor laparotomic hepatectomy compared with epidural analgesia, monitoring visual analog scale (VAS). The investigators expect at least the same post-operative pain control in the two groups (non inferiority of pain control with spinal analgesia compared to epidural analgesia). Second endpoint is to verify whether after spinal analgesia there is a decrease in patient's length of hospitalization according to enhanced recovery after surgery (ERAS) principles.
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.
