Background and Objectives: The purpose of this study is to evaluate the level of oxidative stress before and after breast cancer surgery. Materials and Methods: Malondialdehyde (MDA) level was tested using a thiobarbituric acid (TBA) assay based on the release of a color complex due to TBA reaction with MDA. The glutathione S-transferase (GST) activity was evaluated by enzymatic conjugation of reduced glutathione (GSH) with 1-chloro-2,4-dinitrobenzene. The level of total glutathione (reduced GSH and oxidized GSSG) was detected using a recycling system by 5,5-dithiobis(2-nitrobenzoic acid). The levels of the indices were determined in the serum of 52 patients before surgery, two hours and five days after surgery, and in 42 healthy women. Results: In the patients over 50 years old the level of MDA was higher after surgery in comparison with before surgery, and GST activity was lower in comparison with the control. The GSH + GSSG level in both ages groups after surgery was lower than in the control. Significant differences of MDA level were detected in patients with stage III after surgery compared to the control. The level of GSH + GSSG was significantly lower in the patients with I–III stages compared to the control. Conclusion: The most expressed changes demonstrate the significance of MDA as a marker to evaluate oxidative stress in breast cancer patients. The degree of oxidative stress depends on the patient’s age and stage of disease. (1) Malondialdehyde can be used as an oxidative stress marker; (2) A higher stage of the disease and older age correspond to a higher rise of malondialdehyde, suggesting more intensive oxidative stress.

FCS8829, a 4-page fact sheet by Martha C. Monroe and Barbara F. Shea, is intended for breast cancer patients who are preparing for their lumpectomy or mastectomy surgery. It helps patients understand what to expect before and after surgery. Includes information on understanding medical procedures and coping physically and psychologically. Also features quotes and experiences from other breast cancer patients. Published by the UF Department of Family, Youth and Community Sciences, April 2007.

               Oxidative stress occurs as a result of disturbance in the balance between the production of reactive oxygen species (free radicals) and antioxidant defenses. Markers of oxidative stress were measured the markers of oxidative stress in breast cancer patients after diagnosis of breast cancer and compared these plasma blood levels controls This study was conducted to three markers of oxidative stress ;these are (SOD) enzyme ,malondialdehyde (MDA)and8-iso-prostaglandinF2α plasma of patients with breast cancer and compare with controls .In this study ;  the mean MDA (ng/ml) levels for the breast cancer patients and the controls were55.91±3.31 and40.61±3.76  respectively, while the SOD (pg/ml) levels were1530.37±80.4 and1851.4 9±93.65  respectively and the 8-iso-PGF2α (ng/ml ) levels were 40.16±3.31 and 30.16±2.34  difference of the mean were statistically significant (p value <0.05).

Objective: To evaluate the effectiveness and feasibility of Managing Cancer and Living Meaningfully (CALM), which is used to reduce chemotherapy-related cognitive impairment (CRCI), relieve psychological distress, and improve quality of life (QOL) in Chinese breast cancer survivors (BCs). Methods: Seventy-four BCs were enrolled in this study. All patients were randomly assigned to either the CALM group or the care as usual (CAU) group. All patients were evaluated by the Functional Assessment of Cancer Therapy–Cognitive Function (FACT-Cog), Distress Thermometer (DT), and the Functional Assessment of Cancer Therapy–Breast (FACT-B) before and after CALM or CAU application to BCs with CRCI. We compared the differences in all these scores between the CALM group and the control group and analyzed the correlation between cognitive function and QOL. Results: Compared with the CAU group, the performance of the CALM group on the FACT-Cog, DT, and FACT-B showed significant differences before and after CALM ( t = −18.909, −5.180, −32.421, P = .000, .000, .000, respectively). Finally, there was a positive correlation between cognitive function and QOL in breast cancer patients before ( r = 0.579, P = .000) and after ( r = 0.797, P = .000) treatment. Conclusions: The present results indicated that CALM has salutary effects on the improvement of cognitive impairment and QOL and relieves psychological distress in breast cancer patients, which may be due to a positive correlation between psychological distress and cognitive function or QOL.

<b><i>Introduction:</i></b> The aim of this study was to evaluate the accuracy and reliability of the Magseed magnetic marker in breast cancer surgery. <b><i>Methods:</i></b> Thirty-nine patients with 41 implanted Magseeds undergoing surgical treatment in 3 surgical oncology departments were included in the retrospective trial to study pilot use of the Magseed magnetic marker in the Czech Republic for localisation of breast tumours or pathological axillary nodes in breast cancer patients. <b><i>Results:</i></b> Thirty-four breast cancer and 7 pathological lymph node localisations were performed by Magseed implantation. No placement failures, or perioperative detection failures of Magseeds were observed (0/41, 0.0%), but one case of Magseed migration was present (1/41, 2.4%). All magnetic seeds were successfully retrieved (41/41, 100.0%). Negative margins were achieved in 29 of 34 (85.3%) breast tumour localisations by Magseed. <b><i>Conclusion:</i></b> Magseed is a reliable marker for breast tumour and pathological axillary node localisation in breast cancer patients. Magseed is comparable to conventional localisation methods in terms of oncosurgical radicality and safety.

SummaryWe studied the occurrence of myocardial infarction (MI), ischaemic stroke (IS) and pulmonary embolism (PE) before and after breast cancer hospitalisation compared with cancer-free controls. For this, women with a first breast cancer hospitalisation during 2000–2007 were selected from the PHARMO Record Linkage System, including drug use and hospitalisations of three million inhabitants in the Netherlands, and matched 1:10 by age to cancer-free women. The occurrence of MI, IS and PE were assessed in the 12 months before and after breast cancer hospitalisation. The study included 11,473 breast cancer patients, with a mean (± SD) age of 59 (± 14) years. Breast cancer patients were two to three times as likely as their cancer-free controls to have had a hospitalisation for PE, MI or IS in the 12 months before diagnosis, though prevalence was <1% in all groups. Breast cancer patients experienced an extreme high risk of PE in the first six months after diag- nosis (hazard ratio [HR] 23.5, 95% confidence interval [CI] 11.1–49.7 compared to controls), which declined gradually to a four times increased risk (HR 3.6, 95%CI 2.4–5.5) more than 12 months after breast cancer hospitalisation. However, incidence was low: less than five events per 1,000 person years during all time periods. For MI and IS we did not observe significant increased HRs after breast cancer hospitalisation compared to controls. Breast cancer patients seem to have a higher risk profile to develop MI and IS, and receive treatment that increases the risk of PE compared to cancer-free controls, although the frequency of hospitalisations was low.
