As the second most popular cancer in the world, breast cancer affects millions of people and causes a large number of deaths every year. Identifying the genetic marker is one of approaches of early diagnosis for following cancer and give a correct treatment. Many recent studies have shown several SNPs including rs10941679 (located at the uptream of MRPS30 gene) are strongly associated with breast cancer in European and other populations. The association between rs10941679 and breast cancer in Vietnamese population has been investigated in this study using High Resolution Melt (HRM) method as a tool for genotyping. HRM was designed on Umelt sofware and was optimized based on annealing temperature and MgCl2 concentration gradient in order to have 3 distinct melting curves from 3 genotypes of rs10941679. The optimal HRM conditions were selected with Tm=58 oC and MgCl2=3.0 mM and 100 Cases/control samples were genotyped by the optimimal HRM condition. The results showed that the frequency of the risk allele G in case and control group were 48.5 % and 54.0 %, respectively. Regression analysis on the presense of the risk allele and risk allele-containing genotypes has shown no association between rs10941679 and breast cancer in Vietnamese population (OR = 0.80; 95% CI = [0.54 – 1.19]; PG = 0.27; PGG/GA = 0.56). The power of this result was estimated to be 12.02 %. To obtain the power up to 90 %, the sample size up to 1691 cases/controls is needed. Due to its low posibility in the assocation with breast cancer in Vietnamese population, rs1094169 is not recommended for further study in finding the genetic for markers cancer in Vietnamese population.

Background: We aimed to investigate the associations of breast cancer (BC) and cancer-related chemotherapies with cytokine levels, and cognitive function. Methods: We evaluated subjective and objective cognitive function in BC patients before chemotherapy and 3~9 months after the completion of chemotherapy. Healthy volunteers without cancer were also compared as control group. Interleukins (IL) 2, 4, 5, 6, 10, 12p70, 13, 17A, 1β, IFNγ, and TNFα were measured. Associations of cancer status, chemotherapy and cytokine levels with subjective and objective cognitive impairments were analyzed using a regression model, adjusting for covariates, including IQ and psychological distress. Results: After adjustment, poorer performance in semantic verbal fluency was found in the post-chemotherapy subgroup compared to controls (p = 0.011, η2 = 0.070); whereas pre-chemotherapy patients scored higher in subjective cognitive perception. Higher IL-13 was associated with lower semantic verbal fluency in the post-chemotherapy subgroup. Higher IL-10 was associated with better perceived cognitive abilities in the pre-chemotherapy and control groups; while IL-5 and IL-13 were associated with lower perceived cognitive abilities in pre-chemotherapy and control groups. Our findings from mediation analysis further suggest that verbal fluency might be affected by cancer status, although mediated by anxiety. Conclusions: Our findings suggest that verbal fluency might be affected by cancer status, although mediated by anxiety. Different cytokines and their interactions may have different roles of neuroinflammation or neuroprotection that need further research.

Background. A new strategy of breast cancer management is required for effective disease prevention and control. Immunotherapy is one of promising options.Objective: to evaluate the effect of immunoadjuvant polyoxidonium on pathmorphological changes in breast tumors.Materials and methods. The study was performed in 75 patients with breast cancer: 50 patients received polyoxidonium in a neoadjuvant regimen (main group), 25 patients did not receive polyoxidonium (control group). Polyoxidonium at a dose of 12 mg was administered intramuscularly 1 time per day on the days 1, 2, 3, 5 and 7 before surgery; on the day 8, radical mastectomy was performed in patients of both groups, followed by histological examination and determination of the grade of therapeutic pathomorphosis of the tumor.Results. The proportion of cases with grade I therapeutic pathomorphosis was 58 %, grade II therapeutic pathomorphosis – 6 %. Pathomorphosis in metastatic lymph nodes was observed in 22.7 % of cases.Conclusion. The anti-tumor effect of polyoxidonium was confirmed on the basis of the induction of pathomorphosis of the tumor tissue of breast cancer.

Background: Breast cancer patients who undergo mastectomy encounter numerous problems, the most annoying of which is lymphedema followed by pain and decreased function in the affected limb. Objectives: This study examined the effect of self-care training on upper limb function and pain after breast surgery. Methods: This quasi-experimental study was performed on two groups of 60 patients with breast cancer in the Oncology Ward of Zahedan University of Medical Sciences in 2021. The patients were selected based on the inclusion criteria and through convenience sampling and were then randomly divided into intervention and control groups. The patients in the intervention group attended self-care training and exercise programs implemented in five sessions in addition to the routine care. One and three months after the intervention, upper limb function and pain were measured with DASH and McGill pain questionnaires. The repeated measures analysis of variance (ANOVA) and Bonferroni test were used to compare the pre-, and post-intervention mean scores and mean differences in the two groups. Results: The mean scores of upper limb function one and three months after the training program in the intervention group were lower than the mean scores of the control group. In other words, the quality of upper limb function was not significantly different despite the changes in the first month, but upper limb function significantly improved three months after the intervention (P < 0.001 vs. P = 0.06). The mean pain scores before, one month, and three months after the intervention in the intervention group were 10.4, 35.7, and 6.26, respectively, and the corresponding values in the control group were 10.8, 41.7, and 21.1, respectively, showing significant differences between the two groups, with the intervention group having lower pain scores than the control group (P = 0.001). Conclusions: Since lymphedema and its consequences, including decreased upper limb function and pain, are very serious issues, medical staff can give priority to this training program and implement it to prevent and control these complications.

Objective: To evaluate the effect of moxibustion on relieving breast cancer–related lymphedema. Materials and Methods: A randomized controlled trial was conducted in our institution from March 2016 to March 2017. All patients (N = 48) with cancer-related lymphedema were allocated to 2 groups: a treatment group, in which moxibustion was performed, and a control group, in which pneumatic circulation was performed with compression garments worn every day. Therapeutic efficacy was evaluated by measuring arm circumference (wrist crease, 10 cm proximal to wrist crease, elbow crease, and 10 cm proximal to elbow crease) and determining the Revised Piper Fatigue Scale score and Visual Analog Scale score for swelling before and after treatment. Results: All patients were treated for 4 consecutive weeks. Compared with 0 week after treatment, the affected-side arm circumference after 4 weeks’ treatment decreased in both treatment and control groups; the difference value in the treatment group was superior to that in the control group. Compared with the controls, moxibustion resulted in a lower Visual Analog Scale score. The Revised Piper Fatigue total scores were improved in both the moxibustion and control group, and there was no significant difference between the 2 groups. Moxibustion reduced the behavioral, sensory, emotional, and cognitive Revised Piper Fatigue scores, but only the behavioral and sensory scores improved in the control group. Conclusion: Moxibustion has potential effect on breast cancer–related lymphedema. We present promising preliminary data for larger randomized trials to enable accurate evaluation of moxibustion as a lymphedema treatment.

This research emphasizes the nurse’s role in incorporating Islamic teaching through the care practices provided in order to promote spiritual well-being in Muslim women with breast cancer undergoing chemotherapy. In addition, religion and spirituality have been recognized as the primary resources for coping. The aim of the study, therefore, was to explore the impact of an Islam-based caring intervention on the spiritual well-being of Muslim women with cancer. Furthermore, data were collected using a questionnaire and, also, the Functional Assessment of Chronic Illness Therapy-Spiritual well-being (FACIT-Sp) on baseline (Time 1), days 3 (Time 2), 23 (Time 3), and 44 (Time 4). The results showed the significant impact of an Islam-based caring intervention on the participants’ level of spiritual well-being. In addition, the mean scores varied between the intervention and control group over time. Based on the reflection, participants stipulated feeling peace of mind, closer to God, spirit for further life, and healthier.

Fifty-nine evaluable patients under 65 years of age with measurable metastatic breast cancer and without prior chemotherapy were randomly assigned to treatment with fluorouracil, Adriamycin (Adria Laboratories, Columbus, OH), and cyclophosphamide (FAC) at standard or high doses (100% to 260% higher than standard FAC) following a dose escalation schedule. Patients randomized to the high-dose FAC received the first three cycles of therapy within a protected environment. Subsequent cycles for this group were administered at standard doses of FAC in an ambulatory setting, the same as for the control group. After reaching 450 mg/m2 of Adriamycin, patients in both groups continued treatment with cyclophosphamide, methotrexate, and fluorouracil until there was disease progression. Analysis of pretreatment patient characteristics showed an even distribution for most known pretreatment factors, although the control group had slightly (but nonsignificantly) more favorable prognostic characteristics. Fourteen patients (24%) achieved a complete remission (CR) and 32 (54%) achieved a partial remission (PR), for an overall major response rate of 78%. There were no differences in overall, CR, or PR rates between the high-dose FAC and control groups. The median response durations were 11 and 10 months for the protected environment and control groups, respectively, and the median survival was 20 months for both groups. Hematologic, gastrointestinal (GI), and infection-related complications were significantly more frequent and severe in the group treated with high-dose chemotherapy. Stomatitis, diarrhea, and skin toxicity were dose-limiting. However, there were no treatment-related deaths. High-dose induction combination chemotherapy with the agents used in this study failed to increase the response rate or survival duration, and resulted in a substantial increase in toxicity.

To observe the clinical effect of nano-carbon adsorption of 5-fluorouracil (5-FU) on Breast cancer lymph node metastasis in New Zealand rabbits. A breast cancer animal model was established by local injection of a VX2 tumor tissue suspension in thirty New Zealand rabbits. An observation group, control group A, and control group B were established using a random number table, with ten rabbits in each group. Once tumors with a diameter ≥5 mm were identified in the lymph nodes, the animals received the intervention. The observation group had nano-carbon-5-FU suspension subcutaneously injected, control group A had 5-FU subcutaneously injected through the ear margin, and control group B had 5-FU subcutaneously injected; all received a drug dose of 30 mg · kg–1. Half of the animals in the three groups were killed following treatment for thirty minutes, while the rest of the animals were killed following treatment for seven days. Tumors and lymphatic metastases were removed. Tumor and lymphatic metastasis volume were compared. H&E stained sections were used to determine the ND of tumor cells. A dTUP TUNEL assay using Terminal Deoxynucleotidyl Transferase (TdT) was used to assess tumor cell apoptosis. The expression level of casapase-3 mRNA in tumors and lymphoid tissues was determined using RT-PCR. After treatment for 30 mins, the observation group exhibited a significantly higher 5-FU concentration in lymph node metastases, and significantly lower 5-FU concentrations in plasma and tumors. Nano-carbon can increase the 5-FU concentration in tumor tissue, as well as enhance the clinical effect of drugs on lymph node metastases.

90 Background: Breast cancer is one the most prevalent cancers among Iranian women. One of the complementary therapies is reflexology. The extant paper has been provided with the objective of determining the effect of reflexology on quality of life of patients with breast cancer undergoing chemotherapy in the breast disease center. Methods: This study is a randomized clinical trial which has been applied to 60 patients suffering from breast cancer under chemotherapy in breast diseases center, in 2012. The patients were selected randomly in three test, control and placebo groups. In test group, reflexology was implemented for 3 weeks and each session lasted half an hour. In placebo group, only relaxation techniques were implemented for 3 weeks, each session lasted 20-30 minutes. Control group received the routine therapies of breast cancer center. Results: Data were collected by standard questionnaires of EORTIC QLQ-C30.V.3 and EORTIC QLQ-BR23.V.3. The questionnaires were filled before intervention and two weeks after applying study. There was no significant difference in demographic characteristics or quality of life score of three groups, before intervention. Total score of quality of life was higher in interventional group compared to placebo group before and two weeks after intervention (p < 0.001) Results also indicated a significant difference in total score of quality of life between three test, placebo, and control groups after intervention (p < 0.001). A considerable improvement was noticed in the different aspects of quality of life in the test group compared to two other placebo and control groups. Conclusions: Reduction of pain, anxiety, nausea, and other symptoms related to cancer in patients suffering from cancer are assumed as the important cases of nursing cares focus, and precise nursing may diminish these symptoms considerably. Using reflexology in patients suffering from breast cancer may improve the quality of life as an effective method, and can be recommended for use in patients with breast cancer if it is supervised by health system personnel.

Objectives –To analyse the cause of death pattern in the cohorts of women included in the Swedish randomised mammography screening trials by comparing the groups of invited and control women both with each other and with the general population of Swedish women. Setting –Since 1977 four randomised trials of mammography screening have been performed in Sweden: Malmö, Kopparberg and ÖOstergötland (the two county trial), Stockholm, and Gothenburg. Design –Overview of four randomised mammography screening trials. Results –The total numbers of deaths in the invited and control groups respectively were 15 695 and 11 887 corresponding to a relative risk (RR) of 1.00. There were no significant differences between the invited and control groups for cause-specific mortality, except for breast cancer. When the total mortality in the invited and the control groups was compared with that for Swedish women in general the standardised mortality ratio was close to 100. Conclusions –The cause of death pattern in the invited group was, except for breast cancer, very similar to that in the control group, showing that the groups were comparable. Similarly, the total mortality including breast cancer mortality in the control group was almost identical to that in Swedish women in general. The same was true, with the exception of breast cancer, for the invited group. These observations confirm that the trial cohorts are representative of Swedish women and indicate that the quantitative results from these trials may safely be generalised to the Swedish population.

Abstract Background The value of preoperative breast MRI as an adjunct technique regarding its effect on re-excision rates has been a subject of discussion. No survival data regarding preoperative breast MRI are available from randomized studies. Methods Ten-year follow-up of the POMB randomized multicentre study was analysed, evaluating MRI and its effect on disease-free survival (DFS) and overall survival (OS). Patients with newly diagnosed breast cancer were randomized to either preoperative MRI or conventional imaging. Kaplan–Meier plots were used to analyse DFS and OS, and Cox regression to estimate hazard ratios (HRs). Results A total of 440 patients, aged 56 years or less, with newly diagnosed breast cancer were randomized to either preoperative MRI (220) or conventional imaging (220; control). Median follow-up for each group was 10 years. DFS rates were 85.5 and 80.0 per cent for the MRI and control groups respectively (P = 0.099). The risk of relapse or death was 46 per cent higher in the control group (HR 1.46, 95 per cent c.i. 0.93 to 2.29). OS rates after 10 years were 90.9 and 88.6 per cent in the MRI and control groups respectively (P = 0.427). The risk of death was 27 per cent higher in the control group (HR 1.27, 0.71 to 2.29). Locoregional, distant, and contralateral recurrence outcomes combined were increased in the control group (P = 0.048). A subgroup analysis of patients with breast cancer stages I–III showed that preoperative MRI improved DFS compared with conventional imaging, but this did not reach statistical significance (P = 0.057). Conclusion After 10 years of follow-up, preoperative breast MRI as an adjunct to conventional imaging resulted in slightly, but non-significantly, improved DFS and OS. Registration number: NCT01859936 (http://www.clinicaltrials.gov).
