Results of Pulmonary Resection: Sarcoma and Germ Cell Tumors

Pulmonary metastasis can be present in as frequently as 88% and 80%, respectively, of patients with sarcoma and germ cell tumour with metastatic disease. In both sarcoma and germ cell tumour, pulmonary metastatectomy may be the only means of rendering a patient disease-free. Sublobar (wedge or segmentectomy), lobectomy, and, rarely, pneumonectomy can be safely performed to achieve complete resection. Bilateral disease can be resected via staged thoracoscopy/thoracotomy, median sternotomy, or clamshell thoracotomy. Finally, multiple resections and re-resections in select patients have resulted in improved survival. The main principle of pulmonary metastatectomy is complete resection. In the appropriately selected patient 5-yr survival rates of as high as 35-52% for sarcoma, and 80% for germ cell tumour can be realized

Diagnosing microscopic pancreatic neuroendocrine tumor using 68-Ga-DOTATATE PET/CT: case series

Neuroendocrine tumors (NETs) are an uncommon diagnosis which often present asymptomatically or with vague symptoms. They can originate from many different organs such as the GI tract, lungs, pancreas and others. 68Gallium DOTATATE positron emission topography/computed topography has been shown to be an effective imaging modality for diagnosing NET and evaluating management options for patients. Here, we present two cases of positive findings in the distal pancreas on the DOTATATE PET/CT scans without any morphological lesion found to be NET in a healthy 48-year-old male and 68-year-old male

Modelli di reti neurali per l'apprendimento in-graph e on-graph.

La tesi affronta il problema dell'apprendimento automatico in domini strutturati, con un focus su grafi solo parzialmente etichettati (in-graph learning). I nuovi modelli neurali proposti integrano ed estendono al caso in-graph un modello per l'apprendimento su grafi completamente etichettati
