Aims: This study, conducted in a 'field-practice' scenario, investigates the effectiveness and safety of everolimus in the second-line treatment of metastatic renal cell carcinoma (mRCC) patients. Patients & methods: mRCC patients, who started everolimus 10 mg/day after failure of first-line VEGF receptor-targeted tyrosine kinase inhibitor, were included in this study. Study end points were treatment response, progression-free survival and tolerability. Results: In total, 100 patients were assessed; the median duration of everolimus treatment was 7.1 months (95% CI: 5.7-8.5). A total of 19% of patients experienced a partial response and 62% of patients reached a stable disease. Median progression-free survival was 8 months (95% CI: 6.7-9.3). A total of 75% of patients experienced adverse events; no grade 4 adverse events were reported. Conclusion: These findings, obtained in a 'field-practice' scenario, support the use of everolimus for mRCC patients who failed one VEGF receptor-targeted tyrosine kinase inhibitor. © 2015 Future Medicine Ltd.

We describe three cases of lymph proliferative diseases characterized by the presence of lymphoma cells expressing the KSHV/HHV-8 antigen with or without EBV expression. The patients were HIV seronegative without serous effusions. One case was diagnosed as KSHV-germinotropic lymphoproliferative disorder due to the presence of atypical plasmablasts involving germinal centers. These plasmablasts were positive for MUM1 and vIL6, co-expressed EBV and LNA-1of HHV-8/KSHV, and showed a polyclonal pattern of Ig gene rearrangements on PCR. The disease was localized and the prognosis was good. In two other cases, a diagnosis of KSHV/HHV-8-related diffuse large cell B-lymphoma morphology was made. The lymphoma cells were anaplastic or frankly pleomorphic, expressed KSHV but not EBV, and were positive for CD20, MUM1, PAX-5, and vIL6. In both cases the prognosis was poor. On the basis of the features observed, we raise three considerations: (1) KSHV-related lymphoproliferative disorders represent a distinctive and heterogeneous group of diseases with variable clinico-pathologic findings and immunophenotypes (BCL6-/MUM1+/CD138- and BCL6+/MUM1+/CD138- or BCL6-/MUM1+/CD138+). (2) Although the pathogenic mechanism of HHV8 in lymphomagenesis is unclear, the presence the viral DNA in lymph nodes of HIV- patients is not a simply opportunistic infection, but is directly implicated in the pathogenesis of KSHV-related diseases; the activation of IL-6 receptor signalling may play an important role in most cases. (3) The different prognoses among different diseases with KSHV etiology may be related to the fact that the pathogenic potential appears to be constrained by a competent immune system. © 2011 The Japanese Society of Hematology.
