3.Factors Influencing Distress in Premenopausal Patients with Breast Cancer Undergoing Endocrine Therapy
Journal of Korean Clinical Nursing Research 2019;25(1):15-24
PURPOSE: The purpose of this study was to investigate relationships among menopausal symptoms, functional status, and distress and to identify factors influencing distress in premenopausal breast cancer patients who had been on endocrine therapy. METHODS: A descriptive correlational study was conducted. Data were collected using questionnaires from 140 patients with breast cancer undergoing endocrine therapy at a general hospital. Data were analyzed using descriptive statistics, t-test, ANOVA, Tukey HSD test, Pearson's correlation analysis and hierarchical regression analysis. RESULTS: The mean scores for menopausal symptom, functional status, and distress were 19.65±7.86, 2.67±0.33 and 3.69±2.19, respectively. The menopausal symptoms and distress were positively correlated (r=.76, p<.001). The menopausal symptoms and functional status (r=−.43, p<.001) and functional status and distress (r=−.31, p<.001) were negatively correlated. The most influential factor for distress was menopausal symptoms (β=.79, p<.001). CONCLUSION: Based on the findings of this study, developing nursing intervention programs focusing on decreasing menopausal symptoms and distress are recommended.

This study was aimed to investigate the reversible effect of tetrandrine, toremifene and their combination on multidrug resistance of K562/A02 cell line. The IC(50) (the concentration causing 50% inhibition of cell growth) of adriamycin (ADR) were assayed by MTT method, the expression of MDR1 mRNA was measured by RT-PCR, the concentration of p-glycoprotein (P-gp) and intracellular ADR were detected by flow cytometry. The results showed that the IC(50) of ADR on K562/A02 and K562 cells were 57.43 and 1.16 mg/L, respectively. The IC(50) of ADR on K562/A02 cells after treatment with tetrandrine, toremifene and both combination were 14.12, 20.74 and 9.14 mg/L respectively, but both drugs did not influence the IC(50) of ADR on K562 cells. Pretreating K562/A02 cells with toremifene (2.5 micromol/L), tetrandrine (1 micromol/L) or both for 72 hours partially restored the sensitivity of K562/A02 cells to ADR. Tetrandrine and toremifene (alone or combination) elevated the ADR concentration in K562/A02, down regulated the expressions of P-gp and MDR1 mRNA. It is concluded that multidrug resistance of K562/A02 cells can be partially reversed by tetrandrine or toremifene, the combination of both drugs shows a higher synergistic reversal effect.

Prostate cancer is a most common malignant neoplasm in males. In recent years, its incidence has been rising dramatically in China. Patients with recurrent prostate cancer may be treated with androgen deprivation strategies, but most cases will eventually develop into androgen-independent prostate cancer (AIPC). Until recently, chemotherapy has been shown to be effective in palliating the symptoms of the disease but not in improving survival. Current strategies for the treatment of AIPC have shown significant palliation, but no definitive increase in survival. Molecular mechanisms underlying the development of androgen-independent prostate cancer (AIPC) are poorly understood. However, there is growing evidence that different molecular profiles may result in the development of AIPC. In this paper, we not only review the molecular mechanism of AIPC, but also present some of the promising management principles and systemic chemotherapy options against AIPC.

7.Endocrine Therapy for Breast Cancer.
The Ewha Medical Journal 2014;37(2):83-91
Breast cancer is the second most common cancer in Korean women and its mortality rate has increased steadily. Although breast cancer is heterogeneous tumor, hormone receptor-positive tumors comprise about 75 percent of all breast cancers. Therefore endocrine therapy that works by targeting estrogen receptor is a pivotal treatment for breast cancers. There are selective estrogen receptor modulators, such as tamoxifen and raloxifene, aromatase inhibitors, such as anastrozole, letrozole and exemestane, fulvestrant and luteinizing hormone-releasing hormone agonists used in endocrine therapy. Endocrine therapy is effective in treating early breast cancer as an adjuvant therapy and metastatic breast cancer as a palliative therapy. Also in women who are at high risk for breast cancer, tamoxifen or raloxifene can prevent breast cancer. Studies for neoadjuvant endocrine therapy are emerging. Considering side effects of each drug and overcoming drug resistance are needed to maximize effectiveness of treatment and advance endocrine therapy.

PABCREATIC neuroendocrine tumours are uncommon neoplasms of the pancreas. They may cause a clinical syndrome due to hormone overproduction. Glucagonoma is a rare kind of pancreatic tumors. Here we report a case of glucagonoma. Hypercalcemia occurred when the patient underwent octreotide acetate long-acting release.

Primary endocrine therapy (PET) is often included as a treatment option in elderly women with operable breast cancer. Elderly women tend to have pre-existing comorbidities and are often reluctant to undergo surgery. The benefit of surgery needs to be weighed against a relatively higher potential for operative morbidity and mortality, and a limited life expectancy. But while PET can provide relatively good locoregional control, it is not curative in nature and the possibility of local complications and metastasis remains. We retrospectively reviewed the outcome of PET in a series of 19 elderly women, older than 70 years of age, who had presented with operable non-metastatic breast cancer. Only about a third of these women were deemed medically unfit for surgery; the rest had declined surgery. Compliance was an issue, with almost half of these patients defaulting treatment and follow-up. Local control was achieved in most patients, but disease progression did occur in 5 patients. Three of these patients received additional treatment; which included surgery in 1 patient. PET should therefore not be considered an equivalent alternative to surgery in elderly women who were fi t to undergo surgery. However, having observed that only 1 of the 6 deaths in our study was related to breast cancer, PET does have a role in women whose life expectancy is more likely to be limited by coexisting morbidities than the breast cancer itself.
