Lymphedema is a common complication in breast carcinoma patients undergoing axillary lymph node dissection. Although there is a significant reduction in the lymphedema rate with sentinel lymph node biopsy compared to axillary lymph node dissection, there is some risk after sentinel lymph node biopsy. Axillary reverse mapping, an emerging concept aims at identifying and preserving the draining lymph node of the arm that is invariably devoid of malignancy. This concept if validated may prevent lymphedema in breast carcinoma patients. Axillary reverse mapping node can be identified using a radiotracer or blue dye. We describe the procedure using filtered Tc-SC.

Basophil-Derived IL-4 Production and Its Potential Pro-Tumoural Role in Th2-Polarisation Within Sentinel Lymph Nodes of Primary Cutaneous Melanoma.

Chronic inflammation in the tumour microenvironment (TME) via Th2-polarisation promotes melanoma progression and metastasis, making it a target for immunotherapy. Interleukin (IL)-4 is considered essential for Th2-polarisation in the TME; however, its source remains unknown. Basophils have been postulated as one of its sources.

Background: Lymph node upstaging represents a quality criterion for standardized lymphadenectomy in lung cancer surgery. The aim of the study was to compare whether the quality of standardized lymphadenectomy in lung cancer surgery is comparable in minimally invasive (video-assisted thoracoscopic surgery) and the open approach (thoracotomy). Furthermore, factors associated with lymph node upstaging were assessed, as was its impact on overall survival and progression-free survival.

Individuals diagnosed with Castleman disease (CD) and TAFRO syndrome (characterized by thrombocytopenia, anasarca, fever, bone marrow fibrosis, and organomegaly) displays a wide range of clinical symptoms, including varying patterns of lymph node enlargement, systemic inflammation, and impaired organ function. Some patients may present with both CD and TAFRO syndrome concurrently. A retrospective study conducted across multiple centers in Japan examined 321 cases to determine if the quantity and position of swollen lymph nodes could forecast the clinical progression and intensity of these conditions.

To explore the safety and clinical efficacy of radiofrequency ablation (RFA) for papillary thyroid microcarcinoma (PTMC) located in the isthmus. This prospective study enrolled patients with single isthmus PTMC admitted to General Surgery Department of 983rd Hospital of Joint Logistic Support Force of PLA from 2017 to 2022. After ablation, the ultrasound and contrast-enhanced ultrasound (CEUS) were performed to follow up the outcomes at 1, 3, 6, 12, 18, and 24 months.

Purpose: To develop and validate a prostate-specific membrane antigen (PSMA) PET/CT based multimodal deep learning model for predicting pathological lymph node invasion (LNI) in prostate cancer (PCa) patients identified as candidates for extended pelvic lymph node dissection (ePLND) by preoperative nomograms.
Methods: [Ga]Ga-PSMA-617 PET/CT scan of 116 eligible PCa patients (82 in the training cohort and 34 in the test cohort) who underwent radical prostatectomy with ePLND were analyzed in our study. The Med3D deep learning network was utilized to extract discriminative features from the entire prostate volume of interest on the PET/CT images.
