Immunomodulation of salivary gland function due to cancer therapy
Oral Diseases, EarlyView.Abstract Functional salivary glands (SG) are essential for maintaining oral health, and salivary dysfunction is a persistent major clinical challenge. Several cancer therapies also have off‐target effects leading to SG dysfunction. Recent advances highlight the role of SG immune populations in homeostasis, dysfunction and gland regeneration.

Pituitary Adenoma Segmentation [PDF]
arXiv, 2011 Sellar tumors are approximately 10-15% among all intracranial neoplasms. The most common sellar lesion is the pituitary adenoma. Manual segmentation is a time-consuming process that can be shortened by using adequate algorithms. In this contribution, we present a segmentation method for pituitary adenoma.

Cancer Innovation, Volume 4, Issue 3, June 2025.For cN0 parotid carcinoma, preventive neck dissection may prolong PFS of higher grade tumor types or low‐ and moderate‐differentiation PC, although it does not improve OS. Therefore, neck dissection should be performed in these cohorts. ABSTRACT Objective This study aimed to explore the prognostic effect of neck dissection and to identify risk factors ...

Diagnosis and Treatment of Primary Tracheobronchial Tumors
Cancer Medicine, Volume 14, Issue 9, May 2025.ABSTRACT Background Primary tracheobronchial tumors (PTBTs) are rare but life‐threatening, accounting for approximately 0.2% of all respiratory neoplasms. Owing to their nonspecific clinical symptoms, PTBTs are often initially misdiagnosed as bronchial asthma or bronchitis in the early stages.
