The reasons blacks have higher mortality rates from colorectal cancer (CRC) than non-Hispanic whites are not fully understood. Blacks have higher rates of vitamin D deficiency than non-Hispanic whites, and vitamin D deficiency has been associated with CRC. The authors of this report investigated the association of vitamin D deficiency with excess risk for CRC mortality for blacks in the Third National Health and Nutrition Examination Survey (NHANES III) that was conducted from 1988 to 1994. ⋯ The current findings were consistent with the hypothesis that vitamin D deficiency contributes to excess African-American mortality from CRC.

Comparative Study
Local, regional, and systemic recurrence rates in patients undergoing skin-sparing mastectomy compared with conventional mastectomy.
Although the use of SSM is becoming more common, there are few data on long-term, local-regional, and distant recurrence rates after treatment. The purpose of this study was to examine the rates of local, regional, and systemic recurrence, and survival in breast cancer patients who underwent skin-sparing mastectomy (SSM) or conventional mastectomy (CM) at our institution. ⋯ SSM is an acceptable treatment option for patients who are candidates for immediate breast reconstruction. Local-regional recurrence rates are similar to those of patients undergoing CM. Cancer 2011. © 2010 American Cancer Society.
