Objective: Our purpose was to evaluate the usefulness of integrated 18F-FDG PET/CT in the detection and characterization of nonpalpable supraclavicular lymph node metastasis in patients with the initial diagnosis of lung cancer.
Subjects And Methods: This study was conducted from May 2005 to May 2006 and included 32 consecutively registered lung cancer patients in whom supraclavicular lymph nodes were not palpable but were identified on contrast-enhanced CT or exhibited increased FDG uptake on integrated PET/CT. Three patients had bilateral nodes, for a total of 35 nodes in the 32 patients. Results of cytologic analysis of a specimen obtained with sonographically guided fine-needle aspiration (n = 27), normal initial and follow-up sonographic findings (n = 3), and no change in the size of supraclavicular lymph nodes on follow-up sonography (n = 2) were the reference standards. The presence of supraclavicular lymph node metastasis was determined with integrated PET/CT (uptake greater than that of surrounding tissue) and contrast-enhanced CT (node short-axis diameter of 5 mm or more). The diagnostic efficacies of these methods in the detection of supraclavicular lymph node metastasis were compared.
Results: Supraclavicular lymph node metastasis was diagnosed cytologically in 12 (34%) of 35 lesions. The diagnostic accuracies of integrated PET/CT and contrast-enhanced CT in the detection of supraclavicular lymph node metastasis were 71% and 66%, respectively; the difference was not statistically significant. Although the difference was not statistically significant, the sensitivity (92%) and negative predictive value (93%) of integrated PET/CT were higher than those of contrast-enhanced CT.
Conclusion: Because of its high sensitivity and negative predictive value, integrated PET/CT is useful in the detection and characterization of nonpalpable supraclavicular lymph nodes in lung cancer patients.

Background: The second-line treatment of neuroendocrine tumors (NETs) of unknown primary origin remains uncertain. This report presented a patient who received octreotide plus IBI-318 plus anlotinib as a second-line treatment for multiple metastatic NETs of unknown primary lesions after the failure of octreotide plus everolimus.
Case Presentation: A 32-year-old male patient presented with elevated CEA (197.

Background: This study aimed to assess combined supraclavicular lymph node dissection (SLND) and radiotherapy (RT) versus standalone radiotherapy for efficacy in newly diagnosed breast cancer patients with ipsilateral supraclavicular lymph node metastasis (ISLNM).
Methods: Totally 143 ISLNM patients treated between 2014 and 2021 in two medical institutions were examined retrospectively. Patients were divided into two groups to undergo combined SLND and radiotherapy (surgery + RT, n = 73) or radiotherapy alone (RT, n = 70).

Aim: We aimed (1) to determine optimal PET-CT SUV and ultrasound (US) features associated for malignant smallintermediate size supraclavicular lymph nodes (SCN) and (2) to evaluate technical efficacy of core needle biopsy (CNB). Materials and methods: Between 2020 and 2023, CNB of SCN with short-axis less than 15 mm were included. PET-CT was evaluated for optimal SUV cut-off value.

Background: Automation in radiotherapy presents a promising solution to the increasing cancer burden and workforce shortages. However, existing automated methods for breast radiotherapy lack a comprehensive, end-to-end solution that meets varying standards of care.
Purpose: This study aims to develop a complete portfolio of automated radiotherapy treatment planning for intact breasts, tailored to individual patient factors, clinical approaches, and available resources.

The occurrence of genital lymphedema with lower extremity involvement is rare. There is no standard approach in the management of combined genital and lower extremity lymphedema (CGLL). The limited literature available on the management of CGLL reveals the use of multiple procedures, including vascularized lymph node transfer (VLNT), lymphovenous anastomosis (LVA), and debulking.
