Background: Breast cancer is the second leading cause of death due to cancer in women. Triple negative breast cancer (TNBC) is a subgroup with unique behavior. There is a controversy in organ involvement in metastasis. In this study, we planned to define the prognostic factors, survival, and recurrence incidence of patients., Materials and Method: Among the 583 patients with breast mass referred to hematology and oncology clinic in Shariati hospital, Tehran, Iran from March 2005 to March 2015, fifty four patients entered the survival analysis whom we followed for two years until March 2017. Overall survival (OS) and disease-free survival (DFS) and Cumulative recurrence incidences (RI) were estimated. Univariate and multivariate Cox proportional hazards regression was performed to assess risk factors in predicting OS and DFS., Results: Median follow up for the patients was 5.00 years. The five-year OS, DFS and RI were 86.13% (95% CI (71.42-93.59), 63.09% (95% CI (47.04-75.49) and 32.15% (95% CI (19.52-47.43) respectively. Among the factors studied OS, DFS and RI differed significantly only between patients with and without nodal involvement (P = 0.004, P = 0.003, and P = 0.02 respectively). On the other hand, based on the univariate modeling, patients with nodal involvement had a higher risk of breast cancer-specific death (HR: 17.99, P = 0.004). Furthermore, patients with nodal involvement had a higher risk of breast cancer-specific death or recurrence (HR = 5.64, P = 0.008). In Multivariate model, just the nodal involvement significantly changed the hazard for OS (HR = 23.91, P = 0.001). As the nodal involvement was the only significant risk factor at the 0.2 level of significance, we can consider the hazard ratio of lymph node positivity in DFS univariate models as adjusted hazard., Conclusion: The only factor with significant effect on OS, DFS and RI was nodal involvement in the pathology report., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To evaluate the relationship between serum lipids including cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglyceride and erectile dysfunction (ED)., Materials and Methods: From January 2000 to June 2003, 100 patients with organic ED, who were referred to our center, were selected and their lipid profile (Cholesterol, Triglyceride, HDL, LDL) were assessed. The results were compared with those in 100 healthy individuals., Results: Mean age of men in the study and control groups were 43.72 +/- 9.76 and 43.59 +/- 10.51 years, respectively. Mean plasma cholesterol and LDL levels in individuals suffering from erectile dysfunction were significantly higher than controls (P = 0.04 and P = 0.02, respectively). However, no difference in the mean plasma triglyceride and HDL levels was seen. Odds Ratios for high plasma cholesterol level (>240 mg/dl) and high plasma LDL level (>160 mg/dl) were 1.74 and 1.97, respectively (r2 = 0.04 and r2 = 0.04). Using linear regression analysis, the regression coefficient for cholesterol and LDL versus the International Index of Erectile Dysfunction Questionnaire (IIEF) score were -0.036 and -0.035, respectively (95% confidence interval: 0.98 - 2.5 for cholesterol and 1.13 - 2.81 for LDL)., Conclusion: The impact of total cholesterol and particularly LDL on men's erectile function underlines the role of hyperlipidemia treatment in prevention of ED and emerges a holistic management in ED patients.
