Glomerulonephritis after Alemtuzumab Treatment for Multiple Sclerosis: A Report of Two Cases.

Introduction: Alemtuzumab, a humanized monoclonal antibody indicated for the treatment of adult patients with active relapsing-remitting multiple sclerosis (MS), has been associated with increased risk of autoimmune adverse events, including thyroid disorders, immune thrombocytopenia, and renal diseases. Renal immune-mediated adverse events, which have been reported in 0.3% of patients treated with alemtuzumab in MS clinical trials, typically occur within 39 months after the last drug administration.

Conventional and digital Ki67 evaluation and their correlation with molecular prognosis and morphological parameters in luminal breast cancer.

Digital counting methods were developed to decrease the high intra- and inter-observer variability of immunohistochemical markers such as Ki67, with most presenting a good correlation coefficient (CC). Since Ki67 is one of the major contributors to Oncotype DX, it is conceivable that Ki67 expression and the recurrence score (RS) obtained by the multigene panel are positively correlated. We decided first to test to what extent conventional and digital Ki67 quantification methods correlate in daily practice and, second, to determine which of these methods correlates better with the prognostic capacity of the Oncotype DX test.

More than ancillary records: clinical implications of renal pathology examination in tumor nephrectomy specimens.

Background: Nephrectomy is the management of choice for the treatment of renal tumors. Surgical pathologists primarily focus on tumor diagnosis and investigations relating to prognosis or therapy. Pathological changes in non-neoplastic tissue may, however, be relevant for further management and should be thoroughly assessed.
