Association of 21-gene assay (OncotypeDX) testing and receipt of chemotherapy in the Medicare breast cancer patient population following initial adoption.
This study looked at trends in the association of 21-gene assay testing and receipt of chemotherapy in the Medicare breast cancer patient population following initial adoption from 2001 to 2011. The investigators looked at updated SEER-Medicare data from 2004 and 2011. The cohort included 26,009 patients who met inclusion criteria. Assay use was associated with a decrease in absolute percentage use of chemotherapy by 4.5%, which became even more pronounced from 2008-2011 with a decrease of 6.8%.

Characterization of the quality of electroconvulsive therapy among older Medicare beneficiaries.
Electroconvulsive therapy (ECT) is an important therapy for treatment-resistant depression and is especially effective for elderly individuals with depression. This study provides the first US nationally representative description of ECT in the elderly. The investigators concluded that despite substantial evidence of efficacy, ECT use remained rare among elderly patients with depression.

Effects of newly developed chemotherapy regimens, comorbidities, chemotherapy-related toxicities on the changing patterns of the leading causes of death in elderly patients with colorectal cancer.
This study examined the effects of newly developed chemotherapy regimens, comorbidities, and chemotherapy-related toxicities on the changing patterns of the leading causes of death in elderly patients with colorectal cancer (CRC). It found that the risks of CRC-specific death decreased with diagnostic time periods only in chemotherapy recipients.
