Assessment of intratumor heterogeneity for preoperatively predicting the invasiveness of pulmonary adenocarcinomas manifesting as pure ground-glass nodules.

Background: The increased use of low-dose computed tomography (CT) for lung cancer screening has improved the detection of ground-glass nodules. However, as the clinical utility of CT findings to predict the invasiveness of pure ground-glass nodules (pGGNs) is currently limited, differentiating pGGNs that indicate invasive adenocarcinoma (IAC) from those that represent other histological entities is challenging. We aimed to quantify intratumor heterogeneity of lung adenocarcinomas characterized by pGGNs on CT to assess its efficacy in predicting IACs before surgery.

Objective: We sought to develop a predictive model to preoperatively identify patients with hepatocellular carcinoma (HCC) at risk of undergoing futile upfront liver resection (LR).
Methods: Patients undergoing curative-intent LR for HCC were identified from a large multi-institutional database. Futile LR was defined by death or disease recurrence within six months postoperatively.
Segmentectomies: 5-Year Experience Of A Center.

Thoracic Surgery Department - Hospital de Santa Marta, Centro Hospitalar Universitário Lisboa Central, Portugal.
Introduction: Segmental anatomical resections have been a subject of debate in recent years. There is increasing evidence that these procedures may offer some advantages in the treatment of early-stage lung cancer, with overall survival (OS) and disease-free survival (DFS) similar to those seen in lobar anatomical resections.
Materials And Methods: We conducted a retrospective analysis of patients who underwent segmentectomy at Santa Marta Hospital (HSM) between January 2018 and September 2022.
Role of neck dissections in the management of carotid body tumors.

Division of Otolaryngology - Head and Neck Surgery, Department of Surgery Dalhousie University Halifax Nova Scotia Canada.
Objective: Carotid body tumors (CBTs) are rare neoplasms of the paraganglia at the carotid bifurcation. While typically benign, CBTs occasionally exhibit malignancy, metastasizing to nearby lymph nodes. Histopathologic analysis alone is insufficient to confirm malignancy, requiring metastases to non-neuroendocrine tissue for a definitive diagnosis.

Surgical Unit, Centre Hospitalier Vétérinaire St Martin, Allonzier La Caille, France.
Objectives: To report the compartmental location of feline aural inflammatory polyps within the tympanic bulla.
Materials And Methods: Nine client-owned cats with clinical signs and middle ear filling consistent with feline aural inflammatory polyps were prospectively pre-selected and underwent unilateral or bilateral ventral bulla osteotomy. Preoperative and surgical findings, complications and outcomes were recorded.
