Active clinical trials for "Lymphatic Metastasis"

To evaluate the survival impact of extensive lymphadenectomy as part of debulking surgery in stage IVB ovarian cancer with supradiaphragmatic lymph node metastasis.

The status of axillary lymph node (ALN) is an important reference indicator for breast cancer surgery and systemic treatment, which is also an important prognostic indicator for breast cancer. Therefore, it is extremely important for surgeons to accurately determine whether axillary lymph nodes have metastasis and the number of metastatic lymph nodes. The value of ultrasound diagnosing the status of axillary lymph nodes was controversial in recent publications. Therefore, there is a high need to prove the accuracy and precision of ultrasound for axillary lymph node metastasis in breast cancer patients. The aim of this study is to assess the usefulness of ultrasound in the diagnosis of axillary lymph node status in breast cancer patients by gathering in vivo and vitro ultrasonographic parameters to build a clinical useful categorization system

Lymph node status is of major prognostic importance in non-metastatic rectal cancer. For oncological reasons, central arterial ligation of the inferior mesenteric artery (IMA) is suggested. However, there is no conclusive evidence presented for this procedure. This study aimed at investigating the localisation of lymph node metastases and the role of central versus peripheral arterial ligation of in rectal cancer specimens.

This study proposes to establish a CT radiomics-based prediction model for identifying metastasis lymph nodes in esophageal cancer.

Single-institution retrospective analysis for predictive factors of prostate cancer patients presenting with isolated or limited lymph node (LN) recurrence (1-3 lesions) on F-Ccholine PET-CT (CholPET) treated with SBRT between January 2010 and July 2015.

In renal cell carcinoma (RCC) patients, lymph node metastases detection and treatment are the most critical issues in daily clinical decision-making. Indeed, conversely to other oncological settings, a) nodal status imaging, b) sentinel node technique and c) standard lymphadenectomy have been demonstrated inadequate in the staging and management of RCC patients. A novel, accurate, standardized imaging technique is urgently needed in RCC setting to detect macro and micro nodal invasion, to identify those patients who are at higher risk of having nodal metastases, to accurately plan the best management. Recent studies suggested combining 18F-FAZA PET with CT scanning in the detection of cancer-induced hypoxia.The investigators propose to test 18F-FAZA PET-CT in detecting nodal metastases to improve the management of RCC patients.

In this study, we aimed to develop a predictive model of lymph node yield in a series of colon cancer resection specimens with detailed anatomic and surgical technique data.

The aim of this study is intending to provide the optimal procedures of lymph node sorting for pathological examination after curative surgery for gastric cancer, which can discriminate the differences of the status of lymph node metastasis, pTNM classification and prognostic outcome of gastric cancer patients.

To establish and validate a suitable and practical nomogram for primary hospitals to predict the risk of central lymph node metastasis (CLNM) among thyroid papillary carcinoma (PTC) patients based on clinical and ultrasound characteristics among Chinese population，1000 PTC patients were retrospectively reviewed who underwent bilateral thyroidectomy or lobectomy plus central lymph node dissection（CLND） between June 2014 and September 2019 in Sun Yat-sen Memorial Hospital (Guangzhou, South China), and then LASSO regression analysis was performed to screen out the possible predictors. Another 200 PTC patients from the First Affiliated Hospital of Zhengzhou University (Zhengzhou, North China) who underwent bilateral thyroidectomy or lobectomy plus CLND between March 2019 and November 2020 were enrolled to construct the nomogram. The area under the receiver operating characteristic (ROC) curves (AUC), calibration curves and decision curve analysis (DCA) were used to evaluate the nomogram.

Indocyanine green (ICG) is a water-soluble organic dye that is cleared totally through the hepatobiliary system. It has a half-life of 3-4 mins, which allows repeated applications. Near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) imaging has been recently introduced, and has been suggested as a useful tool for the identification and preservation of the parathyroid glands (PGs) during total thyroidectomy (TT). ICG can also be used for sentinel lymph node (SLN) biopsy to predict the micrometastases in central lymph nodes (CLN) in thyroid carcinoma, and central lymph node dissection can reduce local recurrence.
