BACKGROUND Low-dose spiral CT of the chest effectively detects early-stage lung cancer in high-risk individuals. The high rate of benign nodules and issues of making a differential diagnosis are critical factors that currently hamper introduction of large-scale screening programmes. We investigated the efficacy of repeated yearly spiral CT and selective use(More)
Neoangiogenesis and enhanced glucose metabolism in neoplasms are likely to be activated by the same biochemical stimulus; hypoxia. A correlation between these two parameters has been postulated. The objective of this study was to evaluate the relationship between Fluoro-desoxi-glucose uptake at positron emission tomography scan and angiogenesis in lung(More)
Sézary syndrome (SS) is a rare form of cutaneous T-cell lymphoma (CTCL) characterized by a distinct metastatic pattern mainly involving blood and skin. Chemokines and their receptors play a critical role in cellular recruitment and homing to tissues and in the metastatic process of several tumors including non-Hodgkin T-cell lymphomas (NHLs). Here we report(More)
Sézary syndrome (SS) is an incurable leukemic variant of cutaneous T-cell lymphoma and its pathogenesis is still unknown. Diagnosis/prognosis may strongly ameliorate the management of SS individuals. Here, we profiled the expression of 470 microRNAs (miRNAs) in a cohort of 22 SS patients, and we identified 45 miRNAs differentially expressed between SS and(More)
PURPOSE The study investigated the feasibility of a positron-sensitive hand-held detector system for the intraoperative localisation of tumour deposits resulting from intravenous [(18)F]FDG administration. METHODS A total of 17 patients (12 receiving preoperative [(18)F]FDG PET imaging) with various histologically proven malignancies were included.(More)
PURPOSE The human TESTIN (TES) gene is a putative tumor suppressor gene in the fragile chromosomal region FRA7G at 7q31.1/2 that was reported to be altered in leukemia and lymphoma cell lines. In this report, we investigated the effect of TES gene expression in vivo to evaluate a possible role of TES gene in human cancer. EXPERIMENTAL DESIGN We have(More)
Several studies investigated the potential role of imaging modalities in prostate cancer patients in case of biochemical recurrence. However, the role of molecular imaging has not been well established yet. Considering the results of the literature and of our own experience, we tried to summarize the potential applications of (11)C-choline PET/CT in(More)
In this study, we used single nucleotide polymorphism and comparative genomic hybridization array to study DNA copy number changes and loss of heterozygosity for 28 patients affected by Sézary syndrome (SS), a rare form of cutaneous T-cell lymphoma (CTCL). Our data identified, further confirming previous studies, recurrent losses of 17p13.2-p11.2 and(More)
Chemokine and chemokine receptors expressed by normal and neoplastic lymphocytes play a key role in cell recruitment into skin and lymph nodes. The aim of this study was to get further insights into the role of chemokines in pathogenesis and progression of cutaneous T-cell lymphoma (CTCL) with particular regard to Sézary Syndrome (SS), a CTCL variant with(More)
Several case reports describing the coexistence of sarcoidosis and malignancy have been published. Therefore, sarcoidosis should always be considered as a differential diagnosis when a cancer patient develops lymphadenopathy. Positron-emission tomography (PET) 2-[18F]-fluoro-2-deoxy-d-glucose (FDG) combined with computed tomography (CT) is widely used for(More)
