Filter by:This is a non-randomized, open-label, multi-site study to collect safety and efficacy data on an intraoperative imaging system, the LUM Imaging System (LUM015 imaging agent in conjunction with the LUM imaging device), in identifying residual cancer in the tumor bed of female breast cancer patients. During the study, study physicians and clinical staff will complete hands-on training in anticipation of the upcoming pivotal study. Site-specific or user-specific issues related to the use of the device will be identified and addressed. Additionally, the data collected in the study will be used to continue training the tumor detection algorithm of the device. In this study, patients will be injected with LUM015 prior to surgery. The study physicians will perform lumpectomy procedures according to his or her institution's standard of care practice. After the main specimen removal is completed, the study physician will use the LUM Imaging Device to image the tumor bed. Therapeutic shaves will be removed based on the recommendation of the LUM Imaging System. Patients will be followed until their first standard of care post-operative follow-up visit.
This study is designed to confirm the efficacy, safety, and tolerability of blinatumomab in patients with MRD of B- precursor ALL in complete hematological remission including patients with relapse after SCT. The study aims to expand experience generated in previous trials in patients with MRD positive ALL with a focus on additional specific questions.
This phase II trial studies how well an umbilical cord blood transplant with added sugar works with chemotherapy and radiation therapy in treating patients with leukemia or lymphoma. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. The umbilical cord blood cells will be grown ("expanded") on a special layer of cells collected from the bone marrow of healthy volunteers in a laboratory. A type of sugar will also be added to the cells in the laboratory that may help the transplant to "take" faster.
To assess the feasibility, Residual Tumor, complication rate and survival of totally laparoscopic primary cytoreduction in carefully selected patients with Advanced Ovarian Cancer, compared with abdominal primary cytoreduction in a single-Institution, single-surgeon prospective series.
A single-centre, randomised clinical trial of patients affected by periampullary cancer who underwent pancreaticoduodenectomies which included two different types of specimen margination: arm A (multicolour inking) and arm B (monocolour inking). The randomisation of the specimen was made after the resection, blinded for the surgeons involved in the operation. The primary endpoint was the overall R1 resection rate and its difference between the two arms. The secondary endpoints were the R1 resection rate in each margin and its difference between the two arms, and the impact of margin status on survival. A sample size of 18 patients was required.
Cryopreservation of ovarian tissue is offered to young girls and women aged under 35 who have to undergo sterilizing gonadotoxic treatment, with the aim of preserving their fertility. The main part of the ovary is preserved, as primordial and primary follicles are resistant to freezing / thawing protocols. In the absence of other techniques (in vivo maturation, injecting isolated ovarian follicles, etc.) autografting this cryopreserved tissue is currently the only technique allowing fertility to be restored. Autograft is possible only if the indication for ovary cryopreservation is a non-neoplastic pathology or a malignant pathology with a low risk of ovarian metastasis. In other cases of neoplastic pathologies, particularly in cases of acute leukemia, tissue cannot as yet be re-used due to the lack of any codified technique for evaluating residual disease (MRD). The team has for two years been developing and validating a technique to look for residual disease in fragments of ovarian cortex in cases of acute leukemia. This technique is based on an original protocol for dissociating ovarian tissue to obtain a population of isolated ovarian cells that may be analyzed by multicolor flow cytometry. The specificity and sensitivity of the technique have been demonstrated in an experimental model. This model consists in using 8 color flow cytometry to look for characterizable leukemia cells added in different dilutions to a population of isolated ovarian cells taken from model ovarian cortex and up to a dilution of 10-5. When the molecular markers were present on diagnosis, they were found by Real-Time Quantitative Polymerase Chain Reaction (RQ-PCR) with the same dilutions. The model tissue came from laparoscopic ovarian drilling in patients with polycystic ovary syndrome. The main objective of this project is to validate techniques that have been previously codified with different populations of leukemia cells that may be characterized. The investigators then aim to adapt and validate this technique to look for MRD using 8 color flow cytometry on cryopreserved fragments of ovarian cortex from leukemia patients that are at risk of metastasis. Secondary objectives will be to implement procedures for oncological qualification of grafts in cases of malignant pathology and to consider the recommendations for using this cryopreserved ovarian tissue through the autograft technique for these indications.

Acute myeloid leukemia(AML) patients with favorable and intermediate cytogenetics at diagnosis are generally excluded from first-line allo-SCT. However, these patients may eventually relapse in some cases. Our previous study found that stratification of treatment based on cytogenetics and therapeutic response could benefit low and intermediate AML. To further verify the results, we conducted a prospective multi-center study. The purpose of this study is to establish risk stratification based on cytogenetics and minimal-residual-disease (MRD) analysis to determine whether a MRD-directed therapy for low and intermediate AML patients has positive results in terms of overall survival.
In this study, the investigators seek to evaluate bone marrow and blood samples and treatment responses to see if Minimal Residual Disease (MRD) can be used as a predictive method of response to treatment in amyloidosis.
Study purpose is to assess the prognostic role of Minimal Residual Disease (defined as medullary expression of WT1 gene), performed at Baseline and during treatment according to clinical practice. MRD results will be relate to treatment outcome and survival analysis variables (Overall Survival, Disease Free Survival, Cumulative Incidence of Relapse)
