Four cycles of docetaxel and cyclophosphamide as adjuvant chemotherapy in node negative breast cancer: A real-world study.

INTRODUCTION: The optimal number of cycles of adjuvant docetaxel and cyclophosphamide (DC) in patients with node negative breast cancer is not known. We aimed to analyse the survival outcomes of patients with node negative and human epidermal growth factor receptor (HER2)-negative breast cancer treated with four cycles of DC. METHODS: Patients with node negative and HER2-negative breast cancer treated with four cycles of DC after surgery in a large Canadian province from 2008 to 2012 were identified. We analysed the 4-year and 9-year invasive disease free survival (iDFS) and overall survival (OS). Cox regression models were constructed to examine the associations of clinical characteristics with survival outcomes. RESULTS: A total of 657 patients were eligible for the current analysis. The median age was 53 years and 71.2% of patients had hormone receptor-positive breast cancer. Approximately three-fourths of patients had grade III tumours. At a median follow-up of nine years, the 4-year iDFS and OS were 91.0% and 95.5% and the corresponding 9-year rates were 80.5% and 88.0%, respectively. On multivariable Cox regression analysis, grade III tumour predicted worse iDFS (hazard ratio [HR], 2.15; 95% confidence interval [CI], 1.09-4.21; P = 0.026) and OS (HR, 3.15; 95% CI, 1.18-8.45; P = 0.022). CONCLUSIONS: Adjuvant chemotherapy with four cycles of DC in a select population of node negative breast cancer was associated with encouraging long-term survival. In the absence of a randomized comparison between four and six cycles of DC, this study presents real-world evidence to consider four cycles of DC as a reasonable option.

Health education to diabetic patients before the start of Ramadan: Experience from a teaching hospital in Dammam.

BACKGROUND AND OBJECTIVE: Studies have shown that pre-Ramadan structured educational program for patients with diabetes mellitus (DM) is beneficial. In this study, our aim was to evaluate the degree of adherence of treating physicians to such programs and their influence on the patient's knowledge and behavior. MATERIALS AND METHODS: This cross-sectional study was carried out on adult patients with DM attending a university hospital, who were observed while fasting during Ramadan 1436/2015. Data was collected using a questionnaire-based interview. Baseline characteristics were obtained, and patients were asked whether they had had pre-Ramadan education or not and who the provider was. Patients' knowledge of the components of the recommended structured pre-Ramadan educational program was also tested. Comparison between patients who had the education and those who did not was done using Chi-square test and independent samples Student's t-test; p ≤ 0.05 was considered statistically significant. RESULTS: A total of 298 patients with type 1 or type 2 DM were included in the study; 75.5% of the patients were aged 40 years or older. Only 30% had pre-Ramadan education delivered mainly by diabetic educators or the treating physicians (52% and 44%, respectively). Patients who had the education were younger (mean age: 45.6 ± 17.4 vs. 50.3 ± 14.4, respectively, p = 0.0048), had higher educational qualifications, were more likely to be employed, and self-monitored their blood glucose more frequently (p = 0.0001). There was no difference between the two groups with regard to their knowledge of diet and exercise. CONCLUSION: The adherence to the pre-Ramadan educational program by the treating physician was low. It is necessary to increase the awareness about the importance of these programs among health-care professionals. The programs should target the less educated, the unemployed, and older patients.
