Introduction: Breast cancer is one of the most common malignancy in women and is the leading cause of cancer related death worldwide. Reactive oxygen species (ROS) play an important role in the development of tumours. Several mechanisms leading to oxidative stress have been proposed in cancer patients. In this study we aimed to measure and compare the levels of zinc, superoxide dismutase, catalase, vitamin C, vitamin E, and malondialdehyde in breast cancer patients and age matched healthy controls. Methods: In this comparative cross sectional study, 30 confirmed breast cancer cases and 30 age and sex matched controls were enrolled after taking their consent. Blood sample was collected in EDTA vial, and the parameters of oxidative stress were evaluated by spectrophotometric and atomic absorption spectrophotometric methods. Results: Zinc and MDA level were significantly higher (p<0.001) in cases (106.4 µg/dl and 7.12 nmol/ml) compared to controls (89.8µg/ dl and 3.99nmol/ml). In contrast, there were lower catalase, vitamin C and E levels in cases (28.7±14.56, 0.92±0.35 and 0.68±0.13 mg/dl) compared to controls (37.1±14.7,1.62±0.59 and 1.02±0.22 mg/dl) and were statistically significant (p<0.05 and p<0.001). Whereas, superoxide dismutase was lower in cases compared to controls, but was not statistically significant. Conclusion: Zinc was found to be higher in our study as it is a pivotal element in all rapidly growing tissues. Enhanced lipid peroxidation observed in the circulation of breast cancer patients in our study can be attributed to over production of ROS and deficiency of antioxidant defences. Oxidative stress in cancer cells may trigger excessive consumption of antioxidants as a compensatory mechanism which lead to its lower concentration.

For breast cancer, chemotherapy is the most common treatment in the world. In breast cancer patients, oxidative stress leads to accumulation of free radicals, which generate more oxidative stress during chemotherapy. This chemotherapeutic approach also leads to enhanced generation of reactive oxygen species and increased oxidative stress as a result. Blood samples were collected from 30 subjects (15 patients who received wheat grass juice (WGJ) and 15 patients who were only on chemotherapy) in the age range 25-60. The goal of the present investigation was to study the relationship between oxidative stress and breast cancer by measuring the non-enzymatic antioxidant levels of Glutathione reductase (GSH) and Malondialdehyde (MDA), which are the markers of lipid peroxidation in breast cancer patients and effect of wheat grass juice on these markers. From the results obtained, it was clear that MDA levels were higher whereas GSH levels decreased in breast cancer patients compared with normal controls. Significant changes in the MDA and GSH values were observed between the group receiving WGJ and the group receiving only chemotherapy. The administration of WGJ along with the treatment reduces the extent of oxidative damage and related complications in breast cancer patients.

Background: Oxidative stress occurs as a result of the disturbance in the balance between the production of reactive oxygen species (free radicals) and antioxidant defenses. This is regarded as a possible etilogical factor in production of breast carcinoma, which is the most cmmon cancer among the females both globally as well as in India. Oxidative stress also plays an important role in progression of cancer breast. This study was conducted to compare the levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in breast cancer patients and normal age matched female participants.Methods: This study was conducted in AVBR Hospital, Sawangi (Meghe) among 30 female breast cancer patients admitted in the surgery ward for treatment after being diagnosed with the disease, who attended the hospital from July 2016 to June 2017. Breast cancer patients of stage I and II were included in the study. Patients suffering from any other diseases apart from breast cancer like diabetes, hypertension, thyroid illnesses and other sort of cancers are excluded from the study. For each of the study participant, age and sex matched controls were selected who were mostly the relatives of patients attending the hospital and were devoid of any illnesses. Venous blood sample was collected from all the patients as well as the controls that were used for determination of the levels of SOD (superoxide dismutase) and MDA (malondialdehyde). Written informed consent was taken from all the study participants before drawing the blood samples.Results: Authors have measured the markers of oxidative stress in breast cancer patients after diagnosis of breast cancer and compared theses blood levels with those of the controls. The mean MDA (nmol/ml) levels for the breast cancer patients and the controls were 26.14 and 15.83 respectively, while the SOD (U/gm Hb) levels were 0.12 and 0.16 respectively and the difference of the mean were statistically significant (p value <0.01).Conclusions: There is presence of increased oxidative stress in breast cancer patients as compared to the healthy controls.

Background Complementary and alternative medicine (CAM) is becoming more common in medical practice, but little is known about the concurrent use of CAM and conventional treatment. Therefore, the aim was to investigate the types of CAM used and their prevalence in a regional patient cohort with breast cancer (BC). Methods BC patients were interviewed with a structured questionnaire survey on the use of CAM in southern Taiwan at an Integrative Breast Cancer Center (IBCC). The National Centre for Complementary and Integrative Health (NCCIH) classification was used to group responses. Over a period of 8 months, all patients receiving treatment for cancer at the IBCC were approached. Results A total of 106 BC patients completed the survey (response rate: 79.7%). The prevalence of CAM use was 82.4%. Patients who were employed, were receiving radiotherapy and hormone therapy, and had cancer for a longer duration were more likely to use CAM ( P < .05). Multivariate analysis identified employment as an independent predictor of CAM use (OR = 6.92; 95% CI = 1.33-36.15). Dietary supplementation (n = 69, 82.1%) was the type of CAM most frequently used, followed by exercise (n = 48, 57.1%) and traditional Chinese medicine (n = 29, 34.5%). The main reason for using CAM was to ameliorate the side effects of conventional therapies. Almost half (46.4%) of these CAM users did not disclose that they were using it in medical consultations with their physicians. Most chose to use CAM due to recommendations from family and friends. Conclusion A large portion of BC patients at the IBCC undergoing anti-cancer treatment courses used CAM, but less than half discussed it with their physicians. Given the high prevalence of CAM, it would be justifiable to direct further resources toward this service so that cancer patients can benefit from a holistic approach to their treatment.

BACKGROUND: Cancer is a disease caused by abnormal growth of body cells that turn malignant and continue to grow uncontrollably. One of the treatments for breast cancer is mastectomy. The quickness of decision-making determines the survival rate of prognosis patients. OBJECTIVE: This study aimed to determine the relationship of self-acceptance with decision-making duration in cancer patients to perform a mastectomy. METHODS: An analytic observation method with cross-sectional design. The samples were taken by purposive sampling method with 50 samples of breast cancer patients. Data collected include age, last level of education, marital status, profession, stage of cancer during mastectomy, self-acceptance score, and decision-making duration to perform a mastectomy. RESULTS: The data analyzed with the Kruskal–Wallis test. The test showed the relationship of self-acceptance (p = 0.027) with decision-making duration in breast cancer patients to perform a mastectomy. CONCLUSION: In Conclusion, there is a relationship of self-acceptance with decision-making duration in breast cancer patients to perform a mastectomy.

(1) Background: Evidence suggests that organizational processes of hospitals have an impact on patient-professional interactions. Within the nurse-patient interaction, nurses play a key role providing social support. Factors influencing the nurse-patient interaction have seldomly been researched. We aimed to examine whether the process organization in hospitals is associated with breast cancer patients’ perceived social support from nurses.; (2) Methods: Data analysis based on a cross-sectional patient survey (2979 breast cancer patients, 83 German hospitals) and information on hospital structures. Associations between process organization and perceived social support were analyzed with logistic hierarchical regression models adjusted for patient characteristics and hospital structures.; (3) Results: Most patients were 40–69 years old and classified with UICC stage II or III. Native language, age and hospital ownership status showed significant associations to the perception of social support. Patients treated in hospitals with better process organization at admission (OR 3.61; 95%-CI 1.67, 7.78) and during the hospital stay (OR 2.11; 95%-CI 1.04; 4.29) perceived significantly more social support from nurses.; (4) Conclusions: Designing a supportive nursing work environment and improving process organization in hospitals may create conditions conducive for a supportive patient-nurse interaction. More research is needed to better understand mechanisms behind the associations found.

Abstract Gallic acid has been identified as an antioxidant component of the edible and medicinal plant Peltiphyllum peltatum. The present study examined its potential protective role against sodium fluoride (NaF)-induced oxidative stress in rat erythrocytes. Oxidative stress was induced by NaF administration through drinking water (1030.675 mg m-3 for one week). Gallic acid at 10 mg kg-1 and 20 mg kg-1 and vitamin C for positive controls (10 mg kg-1) were administered daily intraperitoneally for one week prior to NaF administration. Thiobarbituric acid reactive substances, antioxidant enzyme activities (superoxide dismutase and catalase), and the level of reduced glutathione were evaluated in rat erythrocytes. Lipid peroxidation in NaF-exposed rats significantly increased (by 88.8 %) when compared to the control group (p<0.05). Pre-treatment with gallic acid suppressed lipid peroxidation in erythrocytes in a dose-dependent manner. Catalase and superoxide dismutase enzyme activities and glutathione levels were reduced by NaF intoxication by 54.4 %, 63.69 %, and 42 % (p<0.001; vs. untreated control group), respectively. Pre-treatment with gallic acid or vitamin C significantly attenuated the deleterious effects. Gallic acid isolated from Peltiphyllum peltatum and vitamin C mitigated the NaF-induced oxidative stress in rat erythrocytes.

Chemotherapy drugs used to kill or inhibit proliferation of cancer cell that are cytotoxic and causing side effect for breast cancer patients. The side effect of chemotherapy drugs is decreasing the appetite which causing decrease in energy and protein intake, and could affect nutritional status. This study aim to determine the relationship between appetite with energy and protein intake of post chemotherapy breast cancer patients. This research was an analytic observational research using cross sectional design and purposive sampling conducted at Dr. Ramelan Navy Hospital Surabaya with a sample size of 50 patients. Correlation between appetite with energy and protein intake were analyzed using Pearson correlation. The average of energy and protein intake were 976.3±304.2 kcal and 29.4±12.9 g. Pearson correlation test showed signifi cant correlation between appetite as chemoteraphy side effect with energy intake (p=0.000; r=-0.558) and protein intake (p=0.000; r=-0.504). Decreasing of appetite due to chemoterapy reduce the energy and protein intake of breast cancer patient. Patient are suggest to consume foods in small portion but often to maintain adequate energy and protein intake.
