Filter by: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
The goal of this observational study is to identify predictive factors and to develop a risk model predicting para-aortic lymph node metastasis in patients with locally advanced cervical cancer based on the analysis of surgical staging results. The main questions it aims to answer are: - What are the risk factors to predict para-aortic lymph node metastasis in patients with locally advanced cervical cancer? - What is the indication for prophylactic extended-field radiation therapy in patients with locally advanced cervical cancer Individual data of patients with locally advanced cervical cancer treated with surgical staging at our institution from 2020 to 2022 were pooled analysed.Multivariate Logistic regression analysis was used to identify the predictive factors and to develop the prediction model.
In this study, we aim to develop and validate an easy-to-use machine learning prediction model to preoperatively identify the lymph node metastasis status for rectal cancer patients by using these clinical data from three hospitals.
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.
To evaluate the survival impact of extensive lymphadenectomy as part of debulking surgery in stage IVB ovarian cancer with supradiaphragmatic lymph node metastasis.
This is a prospective, multicenter, self-controlled phase 3 clinical trial designed to evaluate the safety and efficacy of an integrin αVβ3-targeted imaging, 99mTc-3PRGD2 SPECT/CT, for diagnosis of lung cancer and mapping the lymph node metastases. The pathological results will be considered as the gold standard and the conventional metabolic imaging by 18F-FDG PET/CT will be used for a head-to-head comparison. The primary objective of this study is to evaluate the efficacy of 99mTc-3PRGD2 SPECT/CT in mapping of lymph node metastasis according to the nodal mapping system released by the International Association for the Study of Lung Cancer in 2009 (IASLC-2009). The secondary objectives include evaluation of 99mTc-3PRGD2 SPECT/CT in detection of lung cancer and the safety of 99mTc-3PRGD2 injection in human beings.
This study explores the feasibility of sentinel lymph node identification in pharynx and larynx cancers using flexible endoscopy-guided tracer injection.
