CT‐derived quantitative imaging metrics for pathological assessment of stage I pulmonary invasive adenocarcinoma: For the diagnostic examination, uAI Intelligent Imaging System was employed

VIEW, EarlyView.
This study explored uAI‐derived quantitative CT features for pathological grading of stage‐I invasive lung adenocarcinoma. Using 5‐fold cross‐validation, the Random Forest model achieved optimal discriminatory performance (mean AUC = 0.799). Attenuation and texture CT features enable non‐invasive grading and may assist clinical decision‐making ...

A broad-range polymerase chain reaction on a formalin-fixed, paraffin-embedded tissue is a powerful diagnostic tool, but requires cautious interpretation: a case report

Frontiers in Medicine
A woman in her mid-50s with Lynch syndrome and a history of malignant neoplasms was found to have a superior vena cava (SVC) thrombus and a necrotic mediastinal mass on surveillance imaging.

Mediastinal aortopulmonary paraganglioma

, 2017
Mediastinal paragangliomas are rare neural-crest derived tumors arising from para-aortic sympathetic chain ganglia in the middle mediastinum and paravertebral ganglia in the posterior mediastinum. They are extremely rare tumors, accounting for 1 to 2 per

Current Advances of Treatments, Therapeutic Targets, Biomarkers, Novel Drugs, and Machine Learning for Hypopharyngeal Squamous Cell Carcinoma

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Hypopharyngeal squamous cell carcinoma (HSCC) is an aggressive subtype of head and neck squamous cell carcinoma with insidious onset, early metastasis, and dismal prognosis. Conventional multimodal therapy achieves limited survival benefit, highlighting an urgent need for refined precision strategies.

Effects of Lymphatic and Venous Invasion Status on Postoperative Prognosis and Metastasis Pattern in Patients With Esophageal Squamous Cell Carcinoma: A Retrospective Cohort Study

World Journal of Surgery, EarlyView.
Lymphovascular invasion (LVI) is a recognized predictor of poor postoperative outcomes in patients with esophageal squamous cell carcinoma (ESCC). However, only a few studies have evaluated lymphatic invasion (LI) and venous invasion (VI) separately across contemporary perioperative strategies.

Resection and a rare type of reconstruction of the superior vena cava with the left brachiocephalic vein [PDF]

Folia Medica
Resection and reconstruction of the superior vena cava (SVC) are required in a selected group of patients with anterior mediastinal tumors and lung neoplasms. We present the case of a 63-year-old woman who underwent invasive type B2 thymoma resection and

Secondary neoplasms of the esophagus [PDF]

, 1987
A review of 62 cases of esophageal involvement by secondary neoplasms is reported. The common routes of esophageal involvement are by direct extension of the tumor from the contiguous or adjacent organs (45.2%), via mediastinal nodes (35.5%), and ...

Interventional oncology in children: Where are we now?

Journal of Medical Imaging and Radiation Oncology, EarlyView.
Abstract Paediatric Interventional Oncology (IO) lags behind adult IO due to a scarcity of specific outcome data. The suboptimal way to evolve this field is relying heavily on adult experiences. The distinct tumour types prevalent in children, such as extracranial germ cell tumours, sarcomas, and neuroblastoma, differ strongly from those found in ...

Thymic carcinoma

Clinical and Biomedical Research, 2016
Thymic carcinomas are a heterogeneous group of aggressive, invasive epithelial malignancies. Their incidence is rare, occurring predominantly in middle-aged men. Here we present the typical imaging findings of a thymic carcinoma.

Lung V5 and Planning Target Volume/Lung Volume Ratio as Independent Risk Factors for ≥Grade 2 Radiation Pneumonitis after Moderately Hypofractionated Radiotherapy: A Retrospective Study

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Lung V5 and the planning target volume/lung volume ratio were identified as independent dosimetric risk factors for clinically significant radiation pneumonitis following moderately hypofractionated radiotherapy for lung cancer. Maintaining V5 < 35% may help mitigate this risk in clinical practice.
