Aim: We aimed to evaluate the amount and quality of the RNA obtained from lymph nodes of non-Hodgkin lymphomas (NHLs) patients using fine-needle aspiration cytology (FNAC), and to develop strategies to overcome eventual technical drawbacks.

Materials And Methods: Twenty-six patients with NHL and 10 tonsils from children submitted to tonsillectomy underwent FNAC. The aspirates were performed using both cytoaspirator (sample A) and syringe and needle (sample B).

Methylation of p16 gene is a relatively frequent molecular finding in multiple myeloma (MM), but its clinical implication is disputable. Cell cycle regulators are now recognized as active in the control of angiogenesis, which is an integral component of pathogenesis and a target for new treatment modalities of this disease. On such background, we focused on determining whether loss of p16 function by methylation could be associated with increased angiogenesis and VEGF expression, and the prognostic relevance of p16 methylation in 50 untreated, newly diagnosed MM patients.

Many patients with follicular lymphoma (FL) achieve response after treatment but complete remission (CR) rates are very low. Thus the majority of them will relapse, mainly those in advanced stage disease, due to the persistence of residual disease. Therefore, this study had the following aims: to determine the presence of bcl-2/IgH rearrangement in peripheral blood of early and advanced stage FL patients after treatment and to correlate it with their clinical situation at the same moment.
