    The Malaysian Tualang honey (TH) is not only cytotoxic to human breast cancer cell lines but it has recently been reported to promote the anticancer activity induced by tamoxifen in MCF-7 and MDA-MB-231 cells suggesting its potential as an adjuvant for the chemotherapeutic agent. However, tamoxifen produces adverse effects that could be due to its ability to induce cellular DNA damage. Therefore, the study is undertaken to determine the possible modulation of the activity of 4-hydroxytamoxifen (OHT), an active metabolite of tamoxifen, by TH in non-cancerous epithelial cell line, MCF-10A, in comparison with MCF-7 cells.

    OBJECTIVE: This study was conducted to determine the prevalence and severity of menopausal symptoms and their associated risk factors among postmenopausal breast cancer patients receiving adjuvant endocrine therapy.

    METHODS: Postmenopausal breast cancer patients on endocrine therapy were recruited at three hospitals in Malaysia. Presence and severity of menopausal symptoms were determined using the Menopause Rating Scale. Sociodemographic and clinical data were collected from medical records.

    RESULTS: A total of 192 patients participated in this study. Commonly reported symptoms were musculoskeletal pain (59.9%), physical and mental exhaustion (59.4%), and hot flushes (41.1%). Multivariate analyses indicated that increasing number of years after menopause until the start of endocrine therapy was significantly associated with less likelihood of reporting menopausal symptoms and musculoskeletal pain. Patients with primary or secondary education levels reported significantly less menopausal urogenital symptoms compared to patients with a tertiary education level. Patients using aromatase inhibitors were twice as likely to experience musculoskeletal pain compared to patients using tamoxifen (odds ratio, 2.18; 95% confidence interval, 1.06-4.50; p

    It is now increasingly common for breast cancer patients to receive adjuvant tamoxifen therapy for a period of up to 10 years. As survival rate increases, managing tamoxifen ocular toxicities is important for patients' quality of life. Macular pigments in photoreceptor cells protect against free radical damage, which can cause macular degeneration. By reducing macular pigment concentration, tamoxifen may increase the risk of macular degeneration. Here, we compared macular pigment optical density (MPOD) and central macular thickness between breast cancer patients on tamoxifen adjuvant therapy (n = 70), and a control group (n = 72). Multiple regression analysis indicated that MPOD decreases with increasing tamoxifen dosage, up to a threshold of about 20 g, after which MPOD plateaus out. Mean MPOD in the treatment group (mean = 0.40) was significantly lower (p-value = 0.02) compared to the control group (mean = 0.47) for the left eye, and for the right eye (treatment mean = 0.39; control mean = 0.48; p-value = 0.009). No significant difference in mean central macular thickness was found between the treatment and the control group (p-values > 0.4). In the control group, MPOD and central macular thickness showed significant correlation (r∼0.30; p-values tamoxifen dosage, and highlight the potential of tamoxifen to reduce macular pigment concentration through an unknown mechanism that does not depend on macular thinning solely.
