Sentinel™ Trial: A Prospective Study Evaluating the Performance and Clinical Benefit of Personalized...
CancerThe Sentinel™ Trial is a non-randomized, large-scale observational trial designed to: 1) evaluate the ability of circulating tumor DNA (ctDNA)-based minimal residual disease (MRD) testing to detect recurrence in advance of standard-of-care techniques across solid tumors, and 2) determine the clinical benefit of therapy in ctDNA-positive participants. The study offers the opportunity to 1) serially monitor participants for ctDNA changes, 2) define ctDNA kinetics across tumor and therapy types, 3) identify participants with ctDNA evidence of MRD, and 4) understand the clinical benefit of ctDNA status on treatment outcomes.

Assessment and Determination of Chemotherapy Resistance in Newly-Diagnosed or First Relapse Leukemia...
LeukemiaThe objective of this protocol is to collect leukemia cell specimens from adults (18 years of age) diagnosed with acute leukemia at time of initial diagnosis and, if applicable, at time of first relapse. These specimens, in conjunction with a de-identified data set, will be utilized prospectively to determine potential chemotherapy resistance in this patient population. The specific aims of this study are as follows: To collect peripheral blood specimens from patients diagnosed with acute leukemia at time of initial diagnosis and, if applicable, at time of first relapse To evaluate the leukemia cells in the blood specimens for chemotherapy resistance utilizing the Hem(A)+ technology To develop a body of evidence from acute leukemia patients that demonstrates the applicability of the Hem(A)+ assay to determine the following: Predict responders and non-responders to common chemotherapeutic agents Track treatment results and comparison to prediction results from the assay Identify optimal chemotherapy doses for each patient Identify the most efficacious pharmaceutical agent combinations

Sentinel Lymph Node Procedure in Ipsilateral Invasive Breast Cancer Relapse
Invasive Breast CancerIpsilateral Recurrence1 moreSentinel lymph node biopsy (SLNB) has become the standard procedure for staging of patients with clinically node-negative breast cancer. Breast-conserving surgery (BCS) has also been a standard treatment for patients with early breast cancer. However, approximately 10% of patients with BCS develop ipsilateral breast tumor recurrence (IBTR), and mastectomy or resection of the recurrent tumor is generally performed. There are no specific guidelines available regarding staging and treatment of the regional lymph nodes. However, the reported risk of axillary lymph node metastasis among patients with local recurrence after breast surgery and a previous negative sentinel node biopsy of 26 % is too high to be ignored. Moreover, evaluation of the regional lymph node basins might be helpful to decide on the indication for adjuvant radiotherapy and systemic treatment. For these reasons it seems sensible to perform a regional lymph node staging procedure in patients with locally recurrent breast cancer. In general practice, this would mean that patients with recurrent breast cancer and a previous negative sentinel node biopsy would receive an axillary lymph node dissection (ALND) and that patients with a previous ALND would receive no additional axillary staging. Lymphatic drainage after previous breast surgery and/or radiotherapy would be altered and it remains questionable whether SLNB at the time of surgery for IBTR (second SLNB) is technically feasible and ALND can safely be omitted. In this study, investigators propose for all patients the realization of SLNB procedure and systematically ALND whatever the results of SLNB analysis, only on patients previously treated with breast conservative surgery. The aim of this study is to evaluate on a homogeneous prospective multicentric cohort of patients the feasibility and the accuracy of a second SLNB procedure for IBTR.

Recurrent Predictive Power of Circulating Tumor Cells for Non Small Cell Lung Cancer Patients
Lung Cancer RecurrentFrom literature review, circulating tumor cell was demonstrated its possible role in disease relapse. It was rare nit could be identified in all lung cancer patients. In addition, circulating tumor cell usual aggregate to form circulating tumor micro-emboli and caused distant metastases. Therefore, circulating tumor cell could play a role in detect disease relapse and appropriate treatment could be given more earlier and further prolong patients' survival. However, the detail clinical significance of circulating tumor still remains unknown. The aim of this study was evaluate the clinical significance, including present timing, numbers, and correlation to disease relapse, of circulating tumor cell in lung cancer patients. The investigators want to clarify the clinical significance between circulating tumor cell and clinical presentation of lung cancer in order to establish new prediction model and improve lung cancer patients' survival.

Prediction of Hepatocellular Carcinoma Recurrence After Curative Treatment by Monitoring Circulating...
Hepatocellular CarcinomaThe goal of the REMNANT study is to confirm the clinical value of detecting a new biomarker, ctDNA (circulating tumor DNA), in the follow-up of patients with operated liver cancer. In order to meet this objective, this biomarker will be measured in your blood before and after surgery, at three and six months.

Recurrence Rate After Laparoscopic Repair of Large Hiatal Hernia
Hiatal Hernia LargePatients who underwent laparoscopic repair of large hiatal hernias and anterior fundoplication with mesh are examined for their recurrence rate one year after surgery.

Rituximab to Prevent Recurrence of Proteinuria
FSGSProteinuriaThe investigators propose to study novel targets of rituximab in podocytes, with a particular focus on recurrent focal segmental glomerulosclerosis (FSGS). The proposed study has strong clinical implications, since it may extend the approved indications for rituximab treatment to recurrent FSGS as well as to other proteinuric diseases. Furthermore, it will offer new insights into the role of sphyngomyelin related enzymes in podocyte function in health and disease, thus allowing the identification of novel targets for antiproteinuric drug development. Finally, the proposed study offers the opportunity to identify a correlation between the patient's specific clinical outcome and the experimental results obtained after exposing podocytes to patient sera in the presence or absence of rituximab. Therefore, it may lead to the development of an assay for the pre-transplant identification of patients at high-risk for recurrent disease and, among them, may allow the identification of those patients that will respond to rituximab.

Recurrent Grade 1 Follicular LymphomaRecurrent Grade 2 Follicular Lymphoma2 moreThis study is designed as a Phase II/III, multi-center trial, comparing two transplant strategies to determine whether non-myeloablative allogeneic Hematopoietic Stem Cell Transplantation (HSCT) will improve long-term progression-free survival compared to autologous HSCT. Recipients will be biologically assigned to the appropriate treatment arm depending on the availability of a Human Leukocyte Antigen (HLA) matched sibling.
