Lenalidomide, an immunomodulatory agent that enhances antibody-dependent cell-mediated cytotoxicity, has the potential to synergize with rituximab, an anti-CD20 mAb. We hypothesized that the addition of lenalidomide to rituximab would improve clinical outcomes in patients with B-cell lymphomas who were previously rituximab resistant, defined as no response to or progression of lymphoma within 6 months of rituximab-based therapy. ⋯ This trial is the first to show that the combination of lenalidomide and rituximab overcomes prior rituximab resistance in patients with indolent B-cell and mantle cell lymphomas.

The increasing prevalence of distant metastases from non-small cell lung cancer (NSCLC) indicates an urgent need for novel therapeutic modalities. Brain metastasis is particularly common in NSCLC, with severe adverse effects on clinical prognosis. Although the molecular heterogeneity of NSCLC and availability of various targeted agents suggest personalized therapeutic approaches for such brain metastases, further development of appropriate preclinical models is needed to validate the strategies. ⋯ Therefore, PDXs from NSCLC brain metastases may better represent the heterogeneous advanced NSCLC population and could be utilized as preclinical models to meet unmet clinical needs such as drug screening for personalized treatments.

The control of cell death involves a complex interaction of multiple proteins. In a study published in the January 1, 2000, issue of Clinical Cancer Research, Tanaka and colleagues demonstrated that one of the proapoptotic proteins, survivin, was frequently expressed in breast cancer. In the subsequent years, effectors of apoptosis have translated into important prognostic indicators and potential therapeutic targets.

Randomized Controlled Trial Multicenter Study
Aspirin, NSAIDs, and risk of prostate cancer: results from the REDUCE study.
A recent meta-analysis showed that aspirin was associated with reduced prostate cancer risk. As anti-inflammatory medications lower PSA levels, whether these findings reflect reduced prostate cancer detection or lower prostate cancer risk is unknown. We tested the association between aspirin and nonaspirin NSAID use on prostate cancer diagnosis in REDUCE, where all men received biopsies at 2 and 4 years largely independent of PSA. REDUCE tested dutasteride for prostate cancer risk reduction in men with a PSA of 2.5 to 10.0 ng/mL and a negative prestudy biopsy. ⋯ Among men with a negative biopsy, aspirin and/or NSAID use was associated with decreased prostate cancer risk. Additional studies are warranted.

The anti-programmed death-1 (PD-1) antibody nivolumab (BMS-936558) has clinical activity in patients with metastatic melanoma. Nivolumab plus vaccine was investigated as adjuvant therapy in resected stage IIIC and IV melanoma patients. ⋯ Nivolumab with vaccine is well tolerated as adjuvant therapy and demonstrates immunologic activity with promising survival in high-risk resected melanoma, justifying further study.
