    Cognitive impairment, colloquially termed "chemobrain", occurs in 10-40% of all cancer patients, and is an emerging target of cancer survivorship research.
    This study reviews published qualitative studies to explore cognitive impairments or chemobrain among breast cancer survivors, with particular attention given to the impact on quality of life.
    Using keywords, we searched ten electronic databases (CINAHL, EMBASE, Proquest, OVID SP, MEDLINE, Oxford Journal, Science Direct, PubMED).
    Of 457 papers, seven relevant papers were included. Data was extracted and concepts were analysed using a meta ethnography approach. Four second order intepretations were identified, on the basis of which, four third order intrepretations were constructed. Linked together in a line of argument, was a consistent account on their struggles to self-manage the chemobrain impairments that impact their daily lives. Five concepts emerged from the analysis of the primary findings: i) real experiences of cognitive changes, ii) calls for help, iii) impact of cognitive impairments, iv) coping and v) survivorship and meaning. Further synthesis resulted in four new order intepretations: i) The chemobrain struggle, ii) The substantial impact of chemobrain on life domains, iii) The struggle to readjust and to self manage, and iv) 'thankful yet fearful' representation.
    Awareness of cognitive changes were context-dependent on healthcare settings and cultural contexts as strong determinants. Subjects verified the existence of chemobrain but healthcare providers mis-recognised, under-recognised, and sometimes negated it perhaps due to its unknown aetiology. Asian breast cancer survivors appear less vocal than their western counterparts.
    The current literature on the lived experiences of how women experienced chemobrain provides a consistent report that chemobrain is real, persistent and with detrimental impacts on quality of life - manifested as a constant struggles. A greater awareness of the effects of chemobrain with improved functional assessment and interventions is warranted.

    Here, we present a case of tonic pupil associated with occult breast cancer as a paraneoplastic neuro-ophthalmology syndrome. A 45-year-old woman developed progressive photophobia and blurred vision due to unilateral Adie's tonic pupil. Magnetic resonance image of her brain and neurological examination (including deep tendon reflexes) were normal at first visit. Follow-up examinations performed by ophthalmologist every 6 month without any change in her condition. After 2 years, patient discovered a mass in her breast which identified to be malignant after diagnostic procedures. Despite surgical and medical treatment for cancer, no change in the ocular condition was happened.

    BACKGROUND: Venous thromboembolism (VTE) is a serious complication of cancer and its treatment. The current study assessed the risk and clinical predictors of VTE in breast cancer patients by time since diagnosis.

    METHODS: This Swedish population-based study included 8338 breast cancer patients diagnosed from 2001 to 2008 in the Stockholm-Gotland region with complete follow-up until 2012. Their incidence of VTE was compared with the incidence among 39,013 age-matched reference individuals from the general population. Cox and flexible parametric models were used to examine associations with patient, tumor, and treatment characteristics, accounting for time-dependent effects.

    RESULTS: Over a median follow-up of 7.2 years, 426 breast cancer patients experienced a VTE event (cumulative incidence, 5.1%). The VTE incidence was 3-fold increased (hazard ratio [HR], 3.28; 95% confidence interval [CI], 2.87-3.74) in comparison with the incidence in the general population and was highest 6 months after diagnosis (HR, 8.62; 95% CI, 6.56-11.33) with a sustained increase in risk thereafter (HR at 5 years, 2.19; 95% CI, 1.80-2.67). Independent predictors of VTE included the following: older age, being overweight, preexisting VTE, comorbid disease, tumor size > 40 mm, progesterone receptor (PR)-negative status, more than 4 affected lymph nodes, and receipt of chemo- and endocrine therapy. The impact of chemotherapy was limited to early-onset VTE, whereas comorbid disease and PR-negative status were more strongly associated with late-onset events.

    CONCLUSIONS: This study confirms the long-term risk of VTE in breast cancer patients and identifies a comprehensive set of clinical risk predictors. Temporal associations with patient, tumor, and treatment characteristics provide insight into the time-dependent etiology of VTE. Cancer 2017;123:468-475. © 2016 American Cancer Society.

    The incidence of synchronous bilateral infiltrating breast cancer has been reported to be 2%. However, synchronous unilateral infiltrating ductal carcinoma and infiltrating lobular carcinoma (ILC) are very rarely reported. We present a woman with palpable ILC who was later found to have synchronous well-circumscribed ductal carcinoma on further imaging. We also discuss the use of diagnostic approaches such as ultrasonography, mammography and histopathology. This case highlights the importance of careful assessment of concurrent lesions in the breast in the presence of an existing carcinoma.

    X-ray microradiography of surgically excised breast specimens offers the possibility of morphological characterization of calcifications. When combined with digital imaging techniques there exists added potential for obtaining valuable basic quantitative morphometric information regarding differences between microcalcifications in tissues exhibiting evidence of fibrocystic change, benign and malignant tumours. A total of 157 excised breast specimens from 84 patients were microradiographed using a Softex Super Soft X-ray unit and Kodak AA high resolution industrial film. A Quantimet 570C image analysis system was used to digitize and analyse the microradiographs. Of the 157 microradiographs, 51 (from 30 patients) revealed microcalcification clusters. The existence of significant differences between the three identified categories of tissue were indicated by clustering parameters. These included the number of particles per cluster, area of clusters, maximum distance to nearest neighbour, and geometric mean distance to nearest neighbour. The distribution pattern index (DPI), another of the clustering parameters used in this study, has been observed to be a particularly powerful discriminator. The value for fibrocystic change was found to be significantly smaller (0.514) than that for benign tumour (0.796) whilst that for benign tumour was observed to be significantly larger than that for malignant tumour (0.604) at a p-value of less than 0.05 (Kruskal-Wallis one-way analysis of variance).

    BACKGROUND: Scalp cooling has been shown in several studies to be an effective method in preventing chemotherapy-induced alopecia (CIA). Data on the use of scalp cooling in Asian countries are limited, and evidence for its use and efficacy among our patients are not available.

    OBJECTIVE: The aim of this study was to assess the effectiveness and tolerability of scalp cooling among breast cancer patients in our study population.

    METHODS: Consecutive breast cancer patients receiving FE75C, FE100C, FE100C-D, docetaxel75 or docetaxel, and cyclophosphamide (TC) at our treatment center were recruited and allocated to the treatment (scalp cooling, DigniCapTM system) or control group in this prospective nonrandomized controlled study. The assessment of alopecia was carried out using the World Health Organization grading system and clinical photographs.

    RESULTS: Seventy patients were recruited, but only 25 completed the study and were evaluable for analysis. Five of 12 patients (42%) in the scalp cooling group managed to preserve hair. Two of three patients who received FE75C and TC regimens had minimal hair loss. All patients treated with FE100C had severe hair loss. Half of all patients who received scalp cooling throughout chemotherapy rated the treatment as reasonably well tolerated. The most common reason for discontinuing scalp cooling was intolerance to its side effects.

    CONCLUSION: Scalp cooling is potentially effective in reducing CIA caused by docetaxel, TC, and FE75C chemotherapy regimen. However, it was not well tolerated by our study population. The dropout rate was high, and this needs to be taken into consideration when pursuing further trials in a similar setting.

    AIMS: Heart failure (HF) patients diagnosed with breast cancer (BC) may have a higher risk of death, and different HF presentation and treatment than patients without BC.

    METHODS AND RESULTS: A total of 14 998 women with incident HF (iHF) or prevalent HF (pHF) enrolled in the Swedish HF Registry within and after 1 month since HF diagnosis, respectively, between 2008 and 2013. Patients were linked with the National Patient-, Cancer-, and Cause-of-Death Registry. Two hundred and ninety-four iHF and 338 pHF patients with BC were age-matched to 1470 iHF and 1690 pHF patients without BC. Comorbidity and treatment characteristics were compared using the χ2 tests for categories. Cox proportional hazard models assessed the hazard ratio (HR) and 95% confidence intervals (95% CIs) of all-cause and cardiovascular mortality among HF patients with and without BC. In the pHF group, BC patients had less often myocardial infarction (21.6% vs. 28.6%, P

    BACKGROUND: Breast cancer is the leading cause of cancer-related death among women in Malaysia. A diagnosis is very stressful for women, affecting all aspects of their being and quality of life. As such, there is little information on quality of life of women with breast cancer across the different ethnic groups in Malaysia. The purpose of this study was to examine the quality of life in Malay and Chinese women newly diagnosed with breast cancer in Kelantan.

    MATERIALS AND METHODS: A descriptive study involved 58 Malays and 15 Chinese women newly diagnosed with breast cancer prior to treatment. Quality of life was measured using the Malay version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast-specific module (QLQ-BR23). Socio-demographic and clinical data were also collected. All the data were analyzed using SPSS version 20.0.

    RESULTS: Most of the women were married with at least a secondary education and were in late stages of breast cancer. The Malay women had lower incomes (p=0.046) and more children (p=0.001) when compared to the Chinese women. Generally, both the Malay and Chinese women had good functioning quality-of-life scores [mean score range: 60.3-84.8 (Malays); 65.0-91.1 (Chinese)] and global quality of life [mean score 60.3, SD 22.2 (Malays); mean score 65.0, SD 26.6 (Chinese)]. The Malay women experienced more symptoms such as nausea and vomiting (p=0.002), dyspnoea (p=0.004), constipation (p<0.001) and breast-specific symptoms (p=0.041) when compared to the Chinese.

    CONCLUSIONS: Quality of life was satisfactory in both Malays and Chinese women newly diagnosed with breast cancer in Kelantan. However, Malay women had a lower quality of life due to high general as well as breast-specific symptoms. This study finding underlined the importance of measuring quality of life in the newly diagnosed breast cancer patient, as it will provide a broader picture on how a cancer diagnosis impacts multi-ethnic patients. Once health care professionals understand this, they might then be able to determine how to best support and improve the quality of life of these women during the difficult times of their disease and on-going cancer treatments.

    PURPOSE: Patient self-management enables living with a chronic disease effectively. This study examines the effectiveness of a 4-week self-management programme to enable self-management of the numerous after-effects and with breast cancer as a chronic disease.
    METHODS: Upon ethical approval, 147 multiethnic survivors (stages I-III breast cancer) received either a 4-week self-management intervention (n = 68) or usual care (n = 78) on a controlled clinical trial in a medical centre. The facilitator-led group intervention provides self-management support and skills for managing the medical, emotional and role tasks. Survivors completed the pre- and post-intervention measures on quality of life, distress and participation inventory.
    RESULTS: Multiple analyses of covariance (adjusted for baseline measures) showed significant differences between groups [F(6, 129) = 2.26, p = 0.04 at post-test and F(6, 129) = 4.090, p breast cancer, by enabling them to better self-manage the numerous medical, emotional and role tasks. Further randomised trials are warranted.
    IMPLICATION FOR CANCER SURVIVORS: Survivors receiving self-management programme report improved HRQL compared with those on usual care. Although time can attenuate the participation limitation and distress of survivors, self-management programmes could help to increase patients' self-efficacy for better self-management.

    BACKGROUND: Breast cancer is one of the most feared diseases among women and it could induce the development of psychological disorders like anxiety and depression. An assessment was here performed of the status and to determine contributory factors.

    MATERIALS AND METHODS: A cross-sectional study was conducted among breast cancer patients at University Kebangsaan Malaysia Medical Center (UKMMC), Kuala Lumpur. A total of 205 patients who were diagnosed between 2007 until 2010 were interviewed using the questionnaires of Hospital Anxiety and Depression (HADS). The associated factors investigated concerned socio-demographics, socio economic background and the cancer status. Descriptive analysis, chi-squared tests and logistic regression were used for the statistical test analysis.

    RESULTS: The prevalence of anxiety was 31.7% (n=65 ) and of depression was 22.0% (n=45) among the breast cancer patients. Age group (p= 0.032), monthly income (p=0.015) and number of visits per month (p=0.007) were significantly associated with anxiety. For depression, marital status (p=0.012), accompanying person (p=0.041), financial support (p-0.007) and felt burden (p=0.038) were significantly associated. In binary logistic regression, those in the younger age group were low monthly income were 2 times more likely to be associated with anxiety. Having less financial support and being single were 3 and 4 times more likely to be associated with depression.

    CONCLUSIONS: In management of breast cancer patients, more care or support should be given to the young and low socio economic status as they are at high risk of anxiety and depression.

    Breast carcinoma is the most common primary tumor producing intraocular metastasis. Metastases to the iris and ciliary body are relatively rare. The authors report a case of a 61-year-old lady, operated for carcinoma of the left breast 3 years back, who presented with symptoms and signs of acute narrow-angle glaucoma in the right eye. A diffuse whitish plaque-like mass in the upper nasal quadrant of the iris with an episcleral nodule on the limbus in the corresponding area and all the signs of acute narrow-angle glaucoma were present in the right eye. Intraocular pressure was controlled medically. Fine-needle aspiration cytology from the episcleral nodule showed malignant cells. Histopathology of the excised nodule showed metastatic poorly differentiated carcinoma, and the cellular pattern was similar to the carcinoma of the breast. There was no other metastasis anywhere in the body. Fine-needle aspiration cytology from an external lesion of the eye is a less invasive and easier procedure than paracentesis to diagnose the metastatic nature of the lesions. The rare features in our case are the clinical presentation as acute glaucoma and the ocular structures being the first and only site of metastasis.

    Breast recurrence of acute lymphoblastic leukaemia (ALL) after stem cell transplant is uncommon, with less than 20 reported cases in the literature. In the majority of cases, the lesions developed without simultaneous involvement of other sites or graft-versus-host disease (GvHD). We describe the first case of simultaneous bilateral breast and ovarian relapses after allografting in ALL, occurring in an 18-year-old female Chinese patient while she was having oral and hepatic chronic GvHD, persistent haematological remission and donor haematopoiesis. She received radiotherapy and chemotherapy, which resulted in resolution of the breast and ovarian lesions, and remained disease free ten months after the onset of the relapse. This case suggests that there may be different mechanisms for bone marrow vs. extramedullary relapses and a complex relationship between GvHD and graft-versus-leukaemia.

    Gastrointestinal disturbances, such as nausea and vomiting, are considered amongst the main adverse effects associated with oral anticancer drugs due to their fast release in the gastrointestinal tract (GIT). Sustained release formulations with proper release profiles can overcome some side effects of conventional formulations. The current study was designed to prepare sustained release tablets of Capecitabine, which is approved by the Food and Drug Administration (FDA) for the treatment of advanced breast cancer, using hydroxypropyl methylcellulose (HPMC), carbomer934P, sodium alginate, and sodium bicarbonate. Tablets were prepared using the wet granulation method and characterized such that floating lag time, total floating time, hardness, friability, drug content, weight uniformity, and in vitro drug release were investigated. The sustained release tablets showed good hardness and passed the friability test. The tablets' floating lag time was determined to be 30-200 seconds, and it floated more than 24 hours and released the drug for 24 hours. Then, the stability test was done and compared with the initial samples. In conclusion, by adjusting the right ratios of the excipients including release-retarding gel-forming polymers like HPMC K4M, Na alginate, carbomer934P, and sodium bicarbonate, sustained release Capecitabine floating tablet was formulated.
