Adrenal lymphoma: presentation, management and prognosis.
International audienceAim:This study aimed to identify the clinical, radiological and prognostic features of primary adrenal lymphoma (PAL) in order to diagnose the disease more accurately.Materials and methods:A retrospective multi-centre study was conducted on the clinical, biological and radiological features as well as the treatment and overall survival outcomes in PAL.Results:Between 1994 and 2014, 28 patients from five regions of eastern France were diagnosed with primary adrenal lymphoma. The revealing symptoms were a worsening general state (77%), weight loss (77%) and abdominal pain (42%). Biological features of PAL were almost omnipresent: increased LDH, β2 microglobulin, CRP or ferritinaemia levels. The PAL was bilateral in 20 cases (71%), adrenal insufficiency was searched for in 11 patients and found in eight (73%). CT scans showed masses of various sizes measuring up to 180 mm. On MRI, the lesions were hypointense in T1 and hyperintense in T2. When done, positron emission tomography with fluorodeoxyglucose (FDG-PET) showed locations not seen on the CT and revealed extra-adrenal locations in 70% of examinations. Adrenalectomy brought no benefit. The overall survival rate was poor (61.9% at 2 years) despite polychemotherapy.Conclusion:The clinical presentation of PAL comprised major general symptoms. Adrenal insufficiency was very common in patients with bilateral involvement but was not systematically tested. PET was an efficient examination to visualize extra-adrenal locations. The preliminary results of MRI to distinguish between PAL and adrenocortical carcinoma should be confirmed. Further studies are needed to establish an optimal strategy for the management of these primary adrenal lymphoma

Mitochondrial apoptosis is induced by Alkoxy phenyl-1-propanone derivatives through PP2A-mediated dephosphorylation of Bad and Foxo3A in CLL
Protein phosphatase 2 A (PP2A) is a tumour suppressor whose strong inhibition underlies the phosphorylation-dependent, anti-apoptotic mechanisms in Chronic Lymphocytic Leukemia (CLL). Inactivation of PP2A is due to the cooperative action of the phosphorylation of Y307 of its catalytic subunit by the aberrant cytosolic pool of the Src Family Kinase Lyn and the interaction with its protein inhibitor SET, which is overexpressed in CLL. In this study, we developed a library of compounds, the most potent being the one named CC11, which restores PP2A activity by disrupting the PP2A/SET complex, thereby triggering the mitochondrial pathway of apoptosis. This process involves the recruitment of the pro-apoptotic BH3-only proteins Bad and Bim to mitochondria, the former upon direct dephosphorylation and the latter being newly expressed upon dephosphorylation and activation of its transcription factor FoxO3a. These findings highlight that PP2A antagonizes the prosurvival pathways controlled by Akt, which phosphorylates and thereby suppresses a variety of pro-apoptotic factors and tumour suppressors including Bad and FoxO3a. Furthermore, the PP2A-mediated pro-apoptotic effect of CC11 is synergistically potentiated by the abrogation of Lyn's activity. Our results show that CC11 represents a promising lead compound for a new therapeutic rationale aimed at abrogating the aberrant oncogenic signals in CLL

Rituximab plus Lenalidomide in Advanced Untreated Follicular Lymphoma
Rituximab plus chemotherapy has been shown to be effective in patients with advanced-stage, previously untreated follicular lymphoma; nevertheless, most patients will have a relapse. Combination immunotherapy with lenalidomide and rituximab is an immunomodulatory regimen that has shown promising activity in patients with indolent B-cell non-Hodgkin's lymphoma
