AbstractCrown-like structures of the breast (CLS-B), defined by the clustering of macrophages (identified using CD68 immunohistochemical staining) to surround a dying adipocyte, are a sign of adipose-tissue inflammation. In human cohorts, CLS-B positively correlates with older age, obesity, dyslipidemia and higher levels of glucose, insulin, C-reactive protein and IL-6. In an existing cohort of early-stage breast cancer patients, CLS-B were identified using H&E stained histologic sections (hCLS-B), and by CD68 immunohistochemistry (CD68 + CLS-B). We examined associations of H&E and CD68-detected CLS-B with clinicopathologic features using χ2 tests, with metabolic factors using Wilcoxon rank sum tests and with disease free and overall survival using Cox regression models. hCLS-B were detected in 59 of 163 patients with slides (36.2%) and CD68 + CLS-B in 37 of 119 patients with paraffin blocks (31.1%). hCLS-B were positively correlated with higher weight (p = 0.003), BMI (p = 0.0008) and C-reactive protein (p = 0.045). CD68 + CLS-B were positively correlated with higher weight (p = 0.006), BMI p = 0.001), leptin (p = 0.034), insulin (p = 0.008) and Homeostasis Model Assessment (p = 0.027). CD68 + CLS-B were associated with poor distant disease-free with a hazard ratio (HR) of 2.81, 95% confidence interval (CI) 1.20–6.57, and overall survival with HR 3.97 (1.66–9.48), while hCLS-B were not associated with either: HR for distant recurrence 0.59 (0.26–1.30); HR for death 1.04 (0.50–2.16). The presence of hCLS-B and of CD68 + CLS-B were associated with obesity; CD68 + CLS-B were associated with insulin resistance and adverse prognosis. Similar patterns were not seen for hCLS-B. Research is needed to understand the biologic basis for these differences.

Circulating Levels

Introduction: Anthracycline-based chemotherapies are widely used chemotherapeutic agents for treatment of breast cancers, but these agents increase inflammation in the cardiovascular system. Circulating levels of high sensitivity C-reactive protein (hsCRP) have been validated to assess the degree of inflammation in adults. While exercise has been shown to reduce hsCRP in patients with coronary artery diseases, it is unclear whether high intensity interval training (HIIT) reduces hsCRP in breast cancer patients undergoing anthracycline-based chemotherapy. Hypothesis: We hypothesized that a group of participants that performed the 8-week HIIT intervention would demonstrate maintenance in hsCRP level compared to a group of participants that did not perform HIIT. Methods: Thirty breast cancer survivors were randomized to either the HIIT or control (CON) group. The HIIT group participated in 8 weeks of supervised exercise sessions 3 times/week. The CON group was asked to maintain their current activity levels. Fasting (≥ 12 hours) blood (∽30 cc) was obtained from the antecubital and hsCRP was measured by immunoturbidimetric assay. A paired t-test and 2x2 (group x time) repeated measures ANOVA were used to evaluate changes in hsCRP. Results: At baseline, there were no group differences in age (46.9±9.8 yrs), BMI (31.0±7.5 kg/m 2 ) and blood pressure (123.4 ± 16.8/72.3.9 ± 5.6 mmHg; p>0.05). Following 8 weeks, hsCRP did not significantly change (7.1±2.7 to 8.7±3.5 mg/L) in the HIIT group (p=0.21). However, there was a significant within-group change in the CON group (6.0±3.2 to 10.9.1±2.3 mg/L; p=0.02). There was no group x time interaction following 8 weeks (P=0.93). Conclusions: An 8-week HIIT intervention maintained circulating levels of hsCRP in breast cancer patients receiving anthracycline-based chemotherapy. Future large randomized controlled trials are warranted to investigate the impact of exercise-induced reductions in inflammation while undergoing anthracycline-based chemotherapy.

Oral Ulcers

Background This study was designed to assess oral ulcerative mucositis, C-reactive protein, blood pressure, heart rate and thyroid function in breast cancer patients in relation to the occurrence of posttraumatic stress disorder (PTSD). Methods A total of 120 female breast cancer patients and women 100 healthy subjects were enrolled in this study. PTSD status was assessed by questionnaire. Before and after treatment (modified radical mastectomy and chemotherapy), serum samples were collected and measured for levels of triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH) and high-sensitivity C-reactive protein (hs-CRP) by ELISA. Oral ulcerative mucositis was evaluated by the number and duration of oral ulcers and the degree of pain. Results Breast cancer patients experienced long-term PTSD and had elevated serum T3 and T4 levels. Patients experienced more severe pain and longer duration of oral ulcers compared with the healthy group. Oral ulcers were significantly associated with PTSD score in terms of the number of ulcers (p=0.0025), the degree of pain (p<0.0001) and the duration of ulcers (p<0.0001). Conclusion These findings support that thyroid function is altered in breast cancer patients with PTSD. Elevation of T3 and T4 and oral ulcerative mucositis might be indicative of the emotional status of breast cancer patients.
