Breast cancer is currently viewed as a heterogeneous disease made up of various subtypes, with distinct differences in prognosis. Our goal was to study the distribution and to characterize the clinical and biological factors that influence the behavior and clinical management of the different molecular breast cancer subtypes in premenopausal African-American women. ⋯ The high prevalence of the basal-cell-like subtype in young premenopausal African-American women aged <35 years may contribute to the poorer prognosis observed in this cohort of African-American women.

Review Meta Analysis
A systematic review and meta-analysis of the randomized controlled trials on adjuvant intraperitoneal chemotherapy for resectable gastric cancer.
The purpose of this systematic review and meta-analysis was to determine the effectiveness and safety of adjuvant intraperitoneal chemotherapy for patients with locally advanced resectable gastric cancer. ⋯ The present meta-analysis indicates that HIIC with or without EPIC after resection of advanced gastric primary cancer is associated with improved overall survival. However, increased risk of intra-abdominal abscess and neutropenia are also demonstrated.

Randomized Controlled Trial Comparative Study
Preoperative immunonutrition suppresses perioperative inflammatory response in patients with major abdominal surgery-a randomized controlled pilot study.
Perioperative administration of immunoenriched diets attenuates the perioperative inflammatory response and reduces postoperative infection complications. However, many questions still remain unresolved in this area, such as the length of diet administration, diet composition, and the mechanisms involved. We performed an open, randomized, triple-arm study comparing the effect of two perioperative feeding regimens with a postoperative one. ⋯ Perioperative administration of an immunoenriched diet significantly reduces systemic perioperative inflammation and postoperative complications in patients undergoing major abdominal cancer surgery, when compared with postoperative diet administration alone. A shortened preoperative feeding regimen of 2 days with Impact enriched with glycine (Impact plus) was as effective as Impact administered for 5 days preoperatively.

Multicenter Study
Outcomes for women with ductal carcinoma-in-situ and a positive sentinel node: a multi-institutional audit.
A positive sentinel lymph node (SLN) has been reported in 6% to 13% of patients with ductal carcinoma in situ (DCIS). Although it is well established that nodal status for invasive disease is prognostically important, the clinical relevance of a positive SLN in patients with DCIS remains undetermined. ⋯ SLN biopsy for high-risk DCIS patients is a mean of detecting those who may have unrecognized invasive disease and therefore are at risk for distant disease.

Early age at onset is often considered a poor prognostic factor for colon cancer. The aim of this study was to determine the association between age, clinicopathologic features, adjuvant therapy, and outcomes following colon cancer resection. ⋯ Younger patients undergoing complete resection of stage I-III colon cancer had DSS similar to older patients. However, younger patients had more nodes retrieved from their specimens and were more likely to receive adjuvant therapy, especially for node-negative disease. These factors may have contributed to their overall favorable outcome.
