Filter by:Existing models do poorly when it comes to quantifying the risk of Lymph node metastases (LNM). This study generated elastic net regression (ELR), random forest (RF), extreme gradient boosting (XGB), and a combined (ensemble) model of these for LNM in patients with T1 esophageal squamous cell carcinoma.
The oncologic benefit of lateral neck dissection (LND) during index operation for sporadic medullary thyroid carcinoma (MTC) basing on basal calcitonin (bCT) levels has been questioned due to the potential post-operative complications. This study aims to evaluate desmoplastic reaction (DSR), as predictor of nodal metastases, for definition of surgical strategy. Data from pathological report of MTC after operations between 1997 and 2022 were collected. The primary endpoint of the study was evaluating the risk factors for nodal metastases. The secondary endpoints analyzed the correlations between DSR and nodal metastases and the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of DSR for nodal metastases.
The goal of this observational study is to learn about in health conditions of ESCC. The main question[s] it aims to answer are: •Lymph node metastasis(LNM) in cervical paraesophageal or supraclavicular which influence OS more. Participants will describe the main status quo after surgery Researchers will compare Lymph node metastasis(LNM) in cervical paraesophageal and supraclavicular to see if dead.
The prognostic implications of lymph node metastasis in colorectal cancer patients at an early stage, specifically T1/2 stage, are relatively unfavorable. Therefore, understanding the clinical and molecular traits relevant to metastasis in T1/2 stage are of substantial clinical importance.
In 2020, Sarda-Inman et al., developed the Ultrasound Neck Node Reporting and Data System (UNN-RADS) scale that allows decision-making about when it is appropriate to perform FNA of a cervical lymph node, evaluating seven ultrasonographic descriptors (shape, margins, echogenicity, echogenicity of the hilum, vascularity and the presence/absence of calcifications, and cystic degeneration), features that have been associated with metastatic lymph nodes, with scores ranging from 0 to 3 points, which allows categorize into 5 different risk groups. Thus, the objective of this study is to evaluate the ultrasound characteristics of metastatic LN in patients undergoing TC follow-up and to validate the UNN-RADS scale for the diagnosis of LN Metastasis in Patients with a history of TC.
The lymph node status is difficult to be assessed preoperatively, this study aimed to develop a scoring system for predicting the risk of LNM in cervical cancer patients before operation.
In our multicenter retrospective study, preoperative CA 19.9 levels predicts the presence of lymph node metastasis at final histology in patients underwent pancreatoduodenectomy for pancreatic ductal adenocarcinoma .
The objective of the study is the analysis of lymphadenectomy in the course of right hemicolectomy, in relation to the radicality of the surgical resection that is performed. In particular, the investigators wants to inquire how according to precise standards regarding surgical radicalness and consequently the anatomical piece that is obtained it is possible to correlate a certain number of lymph nodes and their possible positivity. The lead center is the General and Thoracic Surgery Department of the University of Ferrara. Prof. Anania is the responsible for the enrollment of patients and the coordination with the collaborating centers in the six month-study
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.
Image-guided navigation surgery allows for full utilization of pre-operative imaging during surgery, and has the potential of reducing both irradical resections and morbidity. In this study we will randomize patients which will undergo an abdominal lymph node dissection in order to evaluate the actual technical and clinical benefit of navigation
