Neurosurgical resection is the standard treatment for subependymal giant-cell astrocytomas in patients with the tuberous sclerosis complex. An alternative may be the use of everolimus, which inhibits the mammalian target of rapamycin, a protein regulated by gene products involved in the tuberous sclerosis complex. ⋯ Everolimus therapy was associated with marked reduction in the volume of subependymal giant-cell astrocytomas and seizure frequency and may be a potential alternative to neurosurgical resection in some cases, though long-term studies are needed.

Multicenter Study
Brentuximab vedotin (SGN-35) for relapsed CD30-positive lymphomas.
Hodgkin's lymphoma and anaplastic large-cell lymphoma are the two most common tumors expressing CD30. Previous attempts to target the CD30 antigen with monoclonal-based therapies have shown minimal activity. To enhance the antitumor activity of CD30-directed therapy, the antitubulin agent monomethyl auristatin E (MMAE) was attached to a CD30-specific monoclonal antibody by an enzyme-cleavable linker, producing the antibody-drug conjugate brentuximab vedotin (SGN-35). ⋯ Brentuximab vedotin induced durable objective responses and resulted in tumor regression for most patients with relapsed or refractory CD30-positive lymphomas in this phase 1 study. Treatment was associated primarily with grade 1 or 2 (mild-to-moderate) toxic effects. (Funded by Seattle Genetics; ClinicalTrials.gov number, NCT00430846.).

The Medicare Modernization Act led to moderate reductions in reimbursement for androgen-deprivation therapy (ADT) for prostate cancer, starting in 2004 and followed by substantial changes in 2005. We hypothesized that these reductions would lead to decreases in the use of ADT for indications that were not evidence based. ⋯ Changes in the Medicare reimbursement policy in 2004 and 2005 were associated with reductions in ADT use, particularly among men for whom the benefits of such therapy were unclear.
