Stress can play an important role in development of cancer-related fatigue (CRF) by activating the hypothalamic-pituitary-adrenal (HPA) axis, the sympathetic nervous system (SNS), and altering the immune system. This study examined the influence of catechol-O-methyltransferase (COMT) Val158Met genotypes on salivary markers of HPA axis (cortisol), SNS (α-amylase) and immune (IgA) systems, as well as on CRF in breast cancer survivors (BCS). One-hundred BCS participated. ⋯ No differences in salivary flow rate or IgA concentration (P > 0.20) were found. The results suggest that BCS carrying Met/Met genotype exhibit greater dysfunction of the HPA axis and SNS system associated with severe CRF. This study is important because it strives to understand biological factors that predispose some BCS to higher levels of CRF.

Metastatic breast cancer (MBC) patients with rapid disease relapse after neo/adjuvant chemotherapy including anthracyclines and taxanes have limited treatment options and their efficacy is marginal. Two phase III studies compared ixabepilone plus capecitabine vs. capecitabine alone as first-line treatment in MBC patients pretreated with anthracyclines and taxanes in the neo/adjuvant setting. Here we report the efficacy and safety of these treatments in a prespecified subset of patients whose disease relapsed within 12 months. ⋯ Patients with breast cancer with early relapse following neo/adjuvant treatment with anthracyclines and taxanes may benefit from ixabepilone plus capecitabine. (ClinicalTrials.gov identifiers: NCT00080301 and NCT00082433.).

The standard treatment for Paget's disease of the breast is mastectomy. Since it is frequently associated with underlying carcinoma, many surgeons are reluctant to choose breast conserving surgery for Paget's disease. ⋯ As Paget's disease is frequently accompanied by underlying intraductal and/or invasive carcinoma, patients should be carefully selected for breast conserving surgery.

Review Comparative Study
Is there a case for anti-HER2 therapy without chemotherapy in early breast cancer?
Trastuzumab in combination with chemotherapy is now standard of care for patients with early HER2-positive cancers larger than 1 cm. Some patients however may not need or simply may not want chemotherapy with its associated toxicities. For example patients with small (<1 cm. ⋯ In neoadjuvant trials the combination of trastuzumab and pertuzumab without chemotherapy have achieved pathological complete remission rates in a significant minority of patients, suggesting that a subgroup exists for whom anti-HER2 therapy alone may be as effective as with additional chemotherapy. Trials and prospective studies are now warranted to investigate this issue further in selected patients and these must be accompanied by tissue collection to try to identify predictive biomarkers. Meanwhile there is already enough circumstantial evidence to justify anti-HER2 therapy alone in selected patients for whom chemotherapy is contraindicated.
