Article Abstract
Purpose: Current diagnostic modalities for differentiating between benign and malignant cervical lymph nodes in patients with thyroid cancer are imprecise and time-consuming. The real-time intraoperative detection of malignancy in suspicious lesions could improve the medical management of these patients. This human study was undertaken to evaluate a precise, newly developed Electrical Lymph-Node Scanning (ELS) system to facilitate the effective treatment of cervical LNs in thyroid cancer patients.
Methods: Using the ELS, we examined a collective 109 radiologically suspicious lymph nodes from 36 patients after dissection and compared the ELS results with the histopathological findings.
Results: A total of 27 involved lymph nodes were correctly diagnosed, while 75 reactive or free lymph nodes were correctly identified as uninvolved lymph nodes by ELS (as 3 false negatives and 4 false positives) with total sensitivity and specificity of 90% and 94.9%, respectively. The corresponding negative and positive predictive values were 87.1% and 96.2%, respectively.
Conclusions: Results from this clinical study demonstrate the value of the ELS as a surgical assist adjunct for differentiating equivocal lesions during neck dissection surgery for patients with different types of thyroid cancer.

Objective: This study aims to systematically evaluate the inter- and intra-observer agreement regarding lesions with uncertain malignancy potential in Ga-68 PSMA PET/CT imaging of prostate cancer patients, utilizing the PSMA-RADS 2.0 classification system, and to emphasize the malignancy evidence associated with these lesions.
Methods: We retrospectively reviewed Ga-68 PSMA PET/CT images of patients diagnosed with prostate cancer via histopathology between December 2016 and November 2023.
Number of Examined Lymph Nodes in the Highest Quartile Enhances Staging and Prognosis for Patients with Esophageal Cancer Receiving Neoadjuvant Therapy.

Cancer Center, Renmin Hospital of Wuhan University, Wuhan, China.
Background: The optimal number of examined lymph nodes (ELN) for accurate staging and prognosis for esophageal cancer patients receiving neoadjuvant therapy remains controversial. This study aimed to evaluate the impact of ELN count on pathologic staging and survival outcomes and to develop a predictive model for lymph node positivity in this patient population.
Methods: Data were extracted from the Surveillance, Epidemiology, and End Results (SEER) database and a multicenter cohort.
Impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in right-sided colon cancer: a prospective randomized controlled trial.

Department of Gastrointestinal Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, China.
Aim And Background: This study investigates the impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in patients undergoing radical surgery for right-sided colon cancer. Given that postoperative diarrhea can significantly affect the quality of life, we examined whether dissection boundaries influence these outcomes.
Methods: This was a prospective, randomized controlled trial conducted at a high-volume tertiary hospital.
MRI at 0.55 T for Assessment of Pancreatic Intraductal Papillary Mucinous Neoplasms: An Intraindividual Comparison Versus 1.5-T and 3-T MRI.

Mid-field (0.55-T) MRI may offer an alternative to higher field strengths for pancreatic intraductal papillary mucinous neoplasms (IPMNs) surveillance given high-quality MRCP sequences enabled by longer T2 relaxation times and greater patient comfort resulting from a larger bore and reduced acoustic noise. However, SNR is lower at 0.
