Prognostic value of haematological parameters and [F]FDG PET/CT metabolic parameters in head and neck cancer.

Aim: To determine the usefulness of neutrophil/lymphocyte (N/L) and platelet/lymphocyte (P/L) ratios as well as quantitative [F]FDG PET/CT parameters as prognostic factors for overall survival (OS), cancer-specific survival (CSS) and progression-free survival (PFS) in patients with head and neck squamous cell carcinoma (HyN).

Material And Methods: Sixty-six patients (56 men) diagnosed with HyN carcinoma were retrospectively assessed over an 8-year interval. Maximum SUV (SUV), metabolic tumour volume (MTV) and total lesion glycolysis (TLG) parameters were determined from the PET/CT study at diagnosis.

18F-FDG PET/CT in Extranodal Burkitt Lymphoma.

Burkitt lymphoma (BL) is a poorly differentiated non-Hodgkin B-cell lymphoma, more frequent in children than in adults. The extranodal debut of the disease is rare. We report a 43-year-old male patient with history of dyspnea.
