[18F] Fluorocholine FCH Positron Emission Tomography (PET)/Computed Tomography (CT) for Detection...

Prostate Cancer

The objective of this trial is to assess the value of 18F-choline PET/CT for the detection of regional lymph node metastases from prostate cancer. In addition, the investigators want to evaluate whether 18F-choline PET/CT can replace lymphadenectomy for the staging of prostate cancer.

To Accurately Assess Lymph Node Response to NACT by Wire Localization of Clip-marked Lymph Nodes...

NeoplasmBreast3 more

The investigator developed this protocol to accurately assess lymph node response to neoadjuvant chemotherapy in clinical stage N1 (cN1) breast cancer patients. Accuracy of sentinel lymph node biopsy (SLNB) alone and in combination with the removal of wire-localized-clip-marked nodes will be analyzed. New model to predict lymph node pathological complete remission (pCR) so as to safely avoid axillary lymph node dissection in cN1 breast cancer patients is sought for.

PET in Guiding Cervical Lymphadenectomy (ECTOP-2003)

Esophageal Cancer

Esophageal cancer is the eighth most common cancer around the world, with more than 450000 new cases per year. Esophagectomy with radical lymphadenectomy (2-field lymphadenectomy) is the mainstay of treatment in many countries for patients with esophageal cancer. To improve the survival, 3-field lymphadenectomy combined with cervical lymphadenectomy was started in 1980s. More potential positive lymph nodes were found during more extended lymphadenectomy, offering more accurate TNM staging, affecting consequent treatment. However,3-field-lymphadenectomy was associated with increased surgical morbidity and mortality. Positron emission tomography (PET) is used for detecting distant metastases and lymphatic involvement. The aim of the study is to evaluate the role of PET in predicting cervical lymph metastases of patients with thoracic esophageal squamous cell carcinoma, and to determine if investigators can use PET to guide future cervical lymphadenectomy.

Predictors of Para-aortic Lymph Node Metastasis of Cervical Cancer

Locally Advanced Cervical Cancer

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.

System to Evaluate the Risk of Lymph Node Metastasis Preoperatively in Cervical Cancer

Cervical Cancer

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.

Fluorescence Surgery for Sentinel Node Identification in Melanoma

MelanomaLymph Node Metastasis

Sentinel node biopsy is a surgical procedure used to find melanoma lymph node metastasis (i.e. groin/axilla) in very early stages. This study aims to add a new technology over the standard procedure - a fluorescent contrast (indocyanine green) using special light (near infra-red) - looking for more precise diagnosis of the presence of the lymph node metastasis.

Clinical Validation of a Predictive Model for the Presence of Cervical Lymph Node Metastasis in...

Papillary Thyroid Cancer

This research study is performed to compare the accuracy of two methods of lymph node evaluation: research method versus standard method. Standard method is what is usually performed as standard of care where the radiologist evaluates the images overall and decides whether each node seen should or should not be biopsied. In the research method, a second radiologist will evaluate the ultrasound images of the lymph nodes separately, and use a small specific checklist of ultrasound appearance to determine whether each node should or should not be biopsied. Results of both the standard and research method will be used to decide which node(s), if any should be biopsied. Neck ultrasound examination, lymph node evaluation by standard method and subsequent lymph node biopsy are part of the standard clinical care. It is less likely but possible that the research method may identify additional lymph nodes for biopsy to check if that lymph node contains thyroid cancer.
