Italian Oncological Pain Survey (IOPS): a multicentre Italian study of breakthrough pain performed in different settings.

Objective: A survey of breakthrough pain (BTP) was performed in five palliative care units (PCU), seven oncology departments (ONC), and nine pain clinics (OPC).

Methods: A standard algorithm was used to confirm the diagnosis of BTP of patients refereed to different settings.

Results: 1,412 evaluable cancer patients were enrolled.

CD99 inhibits neural differentiation of human Ewing sarcoma cells and thereby contributes to oncogenesis.

Ewing sarcoma (EWS) is an aggressive bone tumor of uncertain cellular origin. CD99 is a membrane protein that is expressed in most cases of EWS, although its function in the disease is unknown. Here we have shown that endogenous CD99 expression modulates EWS tumor differentiation and malignancy.

Biological indicators of prognosis in Ewing's sarcoma: an emerging role for lectin galactoside-binding soluble 3 binding protein (LGALS3BP).

Starting from an experimental model that accounts for the 2 most important adverse processes to successful therapy of Ewing's sarcoma (EWS), chemoresistance and the presence of metastasis at the time of diagnosis, we defined a molecular signature of potential prognostic value. Functional annotation of differentially regulated genes revealed 3 major networks related to cell cycle, cell-to-cell interactions and cellular development. The prognostic impact of 8 genes, representative of these 3 networks, was validated in 56 EWS patients.

Overcoming resistance to conventional drugs in Ewing sarcoma and identification of molecular predictors of outcome.

Purpose: The improvement of Ewing sarcoma (EWS) therapy is currently linked to the discovery of strategies to select patients with poor and good prognosis and of modified treatment regimens. In this study, we analyzed the molecular factors governing EWS response to chemotherapy to identify genetic signatures to be used for risk-adapted therapy.

Patients And Methods: Microarray technology was used for profiling 30 primary tumors and seven metastases of patients who were classified according to event-free survival.
