The definition of the role of positron emission tomography (PET) in peripheral T-cell lymphomas (PTCLs) is still under investigation. The purpose of the present observational retrospective study was to assess the early prognostic value of PET after the first three cycles of therapy (PET+3), evaluating visual data in de novo PTCL patients treated in first line with standard chemotherapy and followed by both PET and computed tomography scan. Of 27 PET+3-negative patients, 19 also had a negative PET at the end of treatment (PET+6), whereas 8 of 27 had a positive final one; 6 of 7 PET+3-positive patients had a positive PET+6, whereas only 1 patient had a negative PET+6. Estimated overall survival plotted according to PET+3 results showed 78.6% for negative patients and 21.4% for positive patients at 88.7 months with a significant difference. Patients with negative PET+3 had superior progression-free survival of 72.6% compared with 16.7% of PET+3-positive patients. At the time of this analysis, 17 of 19 (89.5%) patients with negative PET+3 are in continuous complete response (CCR) and only 1 of 7 (14.2%) patients with positive PET+3 is still in CCR. In conclusion, our results indicate that positive PET+3 is predictive of a worse outcome in PTCL, and this significant statistical difference between the two curves could be clinically informative. Larger and prospective studies and harmonization of PET reading criteria are needed. © AlphaMed Press 2014.

Myelofibrosis (MF) is the most severe among the classical Philadelphia-negative myeloproliferative neoplasms that also include essential thrombocytemia and polycythemia vera. Myelofibrosis is characterized by numerous genetic lesions, often variously associated with each other, and by an aggressive clinical phenotype leading to severely reduced survival. Also, the inflammatory microenvironment plays a key role in disease initiation and progression. Because of the complexity of its pathogenesis and the variability of clinical features, MF is a disease that requires a personalized approach and remains orphan of curative treatments besides allogeneic transplantation. JAK2 inhibitors have marked a remarkable progress, because they alleviate systemic symptoms and reduce splenomegaly but have a limited effect on survival, on mutation load, and on marrow fibrosis. Here, we review the main contributing factors to MF pathogenesis and prognosis, focusing on how these factors relate to therapeutic choices. We discuss results from ongoing studies of JAK2 inhibitors and report on new therapeutic strategies that proved effective in early preclinical and clinical trials, including combination treatments, antifibrotic agents, and telomerase inhibitors.
