Active clinical trials for "Lymphatic Metastasis"

Gastric cancer with para-aortic lymph node (PAN) involvement is regarded as advanced disease, and only chemotherapy is recommended from the guidelines. In unresectable cases, neoadjuvant chemotherapy could prolong survival if conversion to resectability could be achieved.

The purpose of this research study is to determine how feasible and accurate identifying and removing specific lymph nodes in the axilla (armpit) after neoadjuvant systemic therapy is when patients present with breast cancer that has spread to lymph nodes in the axilla. The specific lymph nodes removed would be determined at the time of diagnosis. If a biopsy proves that cancer has spread to a lymph node, a titanium clip will placed in it to mark it for future removal. That lymph node will be removed after systemic therapy and compared with the rest of the lymph nodes removed from that region.

The aim of the present study is to prospectively compare oncological and functional results of penile radical inguinal lymphadenectomy performed with an open versus videolaparoscopic technique. The main questions it aims to answer are: evaluated the oncological and functional results of inguinal lymphadenectomy performed with minimally invasive techniques using videolaparoscopic instruments vs open inguinal lymphadenectomy according to the standard technique. Participants will undergo treatment of the primary lesion and contextual inguinal lymphadenectomy: Groin 1: open lymphadenectomy performed by a surgical team with extensive experience in traditional surgery Groin 2: laparoscopic lymphadenectomy performed by a surgical team with extensive experience in minimally invasive surgery. The results of these procedures will be prospectively collected and compared.

The purpose of this study is to use Chemo-radio-immunotherapy and maintenance therapy with Nivolumab and Ipilimumab in order to achieve improved outcome in patients with locally advanced cervical cancer.

The primary aim of this study is evaluate the impact of hippocampal-sparing prophylactic cranial irradiation (HS-PCI) on survival status in patients with nodal-positive (locally advanced) adenocarcinoma by comparing overall survival rates of patients undergoing HS-PCI to that of patients without this intervention. In addition, this study aims to investigate whether HS-PCI is detrimental on neurocognitive function and to evaluate its impact on the patient's quality of life.

This study is a clinical feasibility trial that will contribute to the clarification of whether sentinel node mapping with indocyanine green (ICG) provides a better basis for staging of colorectal cancer.

Almost 50 % of papillary thyroid cancer (PTC) patients have central lymph node metastases (CLNM), which are associated with a high risk of persistent or recurrent disease. However, the practice of performing a prophylactic central lymph node dissection (PCLND) routinely remains controversial. The proponents argue that without a PCLND, PTC patients with positive lymph nodes have an increased risk of local recurrence, and postponed node dissection leads to with 5-6 fold higher risk of morbidity. If performed, PCLND in clinical node negative patients increases staging to pN1 in more than 50% of the cases without increasing survival. The complication rate in PCLND is lower when compared to a technically challenging re-exploration in recurrent disease, with reported incidences of 0.6% and 7.3-20%, respectively. Opponents of routine PCLND point out the lack of randomized clinical trials and object to treatment-induced hypo-parathyroidism and recurrent nerve damage for the N0 patients. Currently, no diagnostic tool is available which reliably identifies these patient categories. Therefore, there is a clear need for novel diagnostic imaging modalities that overcome this issue. Molecular Fluorescence Guided Surgery (MFGS) is potentially such a diagnostic tool. The administration of NIR fluorescent tracers can increase detection accuracy of cancer and nodal metastatic tissue using macroscopic MFGS. Therefore, we aimed to identify a GMP-produced near infrared (NIR) tracer that potentially has a high target-to-background ratio in PTC compared to normal thyroid tissue. Tyrosine-protein kinase Met (c-Met) is significantly upregulated at the protein level in PTC compared to normal thyroid tissue. The investigators therefore hypothesize that the GMP-produced NIR-fluorescent tracer EMI-137 (targeting c-Met, peak emission at 675 nm range) might be useful for intraoperative imaging of PTC and nodal metastases. The investigators' aim is to investigate if the administration of EMI-137 is a feasible approach to detect PTC nodal metastases. Ultimately, this method might be useful to improve patient selection for CLND. Eventually, we might also be able to visualize multifocality, more selective lateral neck dissections and asses residual tissue after thyroidectomy. Ultimately, all of these strategies may reduce overtreatment, morbidity, and costs while maintaining the same or better effectiveness with a lower recurrence rate and improved quality of life.

Background: People with prostate, bladder, or kidney cancer often have their cancer spread (metastasize) to lymph nodes. It is important for your doctor to know if this has occurred but currently it can be hard to determine if this has occurred on standard imaging studies like computed tomography (CT) or magnetic resonance imaging (MRI). This study uses an agent called Ferumoxytol to identify lymph nodes that might be involved by cancer. Objective: - To see how well Ferumoxytol can detect lymph node metastases in patients with prostate, bladder, or kidney cancer. Eligibility: -Adults over age 18 with prostate, bladder, or kidney cancer with lymph node involvement. Design: Participants will be screened with a medical history. Participants will have blood drawn and a physical exam. Their vital signs will be measured. They will answer questions about their health and current medications. Participants should not have a history of iron overload or have an allergy to Ferumoxytol. Participants will have a magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder with a strong magnetic field. Participants will lie on a table that slides in and out of the scanner. They will have a standard sensor, known as a coil, wrapped around their abdomen to improve the scan. This is like a small blanket with wiring inside. Participants will need to lie still on the scanning table for about 1 hour. Participants will have an ultrasound. This uses harmless sound waves to provide pictures of organs or tissues inside the body. Participants will receive an injection of Ferumoxytol through an intravenous line. A very thin plastic tube will be inserted into a vein in order to inject the agent. Participants will have another MRI and ultrasound 24 and 48 hours after injection. The study will follow participants medical course for at least 1 year.

The purpose of this research study is to see if a specific kind of MRI can identify small and otherwise undetected abnormal lymph nodes in patients with thyroid cancer who are undergoing surgery. The MRI is called Ultra-Small Superparamagnetic Iron Oxide Magnetic Resonance Imaging (USPIO MRI), and uses an experimental contrast agent (ferumoxytol), to try to identify these lymph nodes. The MRI uses magnetic waves to take images (pictures) of the body and is commonly used in medical testing. Ferumoxytol is FDA approved as an iron replacement product for the treatment of iron deficiency anemia in adult patients with chronic kidney disease. In this research study, the investigators want to see if Ferumoxytol will help to identify very small metastases that are not usually seen on standard MRI scans. If the use of USPIO MRI with the experimental agent ferumoxytol identifies very small metastases in lymph nodes, your surgeon may decide to remove them. After the surgery, the nodes will be stored and then analyzed to assess the ability of USPIO MRI and ferumoxytol to detect cancer in very small metastases in the lymph nodes.

RATIONALE: Diagnostic procedures using fludeoxyglucose F 18 and a surgical probe may help find lymph node metastases in patients with early-stage non-small cell lung cancer. PURPOSE: This clinical trial is studying how well fludeoxyglucose F 18 works in detecting lymph node metastasis in patients with stage I or stage II non-small cell lung cancer that can be removed by surgery.
