In 169 patients with lung cancer the usefulness of physical examination and Daniel's biopsy in detection of metastases to supraclavicular and scalene lymph nodes were evaluated. In 35 patients with palpable lymph nodes and in 25 patients with nonpalpable lymph nodes metastases were confirmed by histological examination. The sensitivity, the specificity and the likelihood ratio of physical examination in detection lymph nodes metastases were respectively: 58%, 86% and 4.1. In 6 patients (5%) among 119 with nonpalpable lymph nodes the positive Daniel's biopsy was the diagnostic procedure. In 5 patients with non-small carcinoma and in 3 patients with malignant mesothelioma positive results of Daniel's biopsy enabled a change of cancer staging and giving up the eventual surgical operation.

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.

A 36-year-old woman with a history of neck swelling was diagnosed with papillary thyroid carcinoma, a common but typically slow-growing thyroid cancer with a good prognosis. Despite frequent lymph node metastasis, mortality rates are low. This cancer can rarely spread to unusual areas like the axillary region.

Background: Prospective randomized trials have demonstrated noninferior survival between sublobar resection and lobectomy in healthy non-small cell lung cancer (NSCLC) patients with tumors ≤2cm. However, some patient attributes are not well represented in randomized trials and uncertainty remains in the widespread applicability of randomized trial nodal dissection protocols.
Methods: Patients with ≤2cm, node-negative NSCLC (cT1N0) in the Society of Thoracic Surgeons prospective database were linked to Medicare survival data using a probabilistic matching algorithm.
