Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts. Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire. Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09). There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045). Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01) and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007), while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002). Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40) were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

Background: Triple-negative breast cancer (TNBC) carries a poor prognosis and therapeutic options are limited to date. The aim of this study was to investigate to what extent the epidermal growth factor receptor (EGFR), vascular endothelial growth factor receptor 2 (VEGFR2), hypoxia inducible factor-1 alpha (HIF-1?) and insulin-like growth factor-1 receptor (IGF-1R) are expressed in TNBC and to determine if these expressions have a predictive role. Methods: Of 923 breast cancer patients who were treated and followed in Academic Center for Education, Culture and Research (ACECR) from 2006-2010, 104 of them had TNBC. Immunohistochemistry analyses were performed on tissue microarray blocks with antibodies for EGFR, VEGFR2, HIF-1? and IGF-1R. Results: We analyzed tumor samples from 104 patients with classic primary invasive ductal carcinoma (IDC). Fifteen patients (14%) were in stage I, 46.6% in stage II, 30.1% in stage III and 5.8% in a metastatic stage (stage IV). The median overall survival (OS) was 48 months. EGFR was expressed in 15 (14%), VEGFR2 in 63 (61%), IGF-1R in 81 (78%) and HIF-1? in 57 (55%) samples. EGFR expression was significantly associated with poor outcome in terms of OS (P = 0.021, OR = 3.9). Conclusions: Among the four investigated tumor markers, only EGFR was significantly associated with survival of patients with TNBC.

Background: Inflammatory breast cancer (IBC), a subgroup of locally advanced breast cancer (LABC), is diagnosed based on clinical findings, and seems to be different from other types of LABC. The purpose of this study was to compare clinicopathological characteristics and outcomes between inflammatory and non-inflammatory LABC patients at Breast Cancer Research Center (BCRC), Tehran, Iran. Methods: The medical records of all patients who were diagnosed as LABC in BCRC since 1997 to 2011 were extracted from the database. Then, clinical and pathological characteristics and overall survival of IBC patients were compared with non-inflammatory LABC (NI-LABC). Results: A total number of 340 patients were identified as LABC from which 17 patients (5%) were diagnosed as IBC. Menopausal status, body mass index (BMI), family history of breast cancer, nodal status, and Her2/neu and PR positivity were not statistically different between IBC and NI-LABC groups. The difference in estrogen receptor (ER) between the two groups was significant (P = 0.028). Median duration of follow-up was 26.50 months. Patients with IBC had overall survival of 27.9 months (95% CI: 22.7–33.1) which was lower than patients in the NI-LABC group with a survival of 118.9 months (95% CI: 107.3–130.6) (P = 0.015). The difference between the disease-free survivals of the two groups were also statistically significant (P < 0.001). Conclusions: Compared to NI-LABC, IBC is more frequently ER negative and more commonly associated with lower survival rate. These findings reinforce the idea that IBC has a more aggressive biology and more unfavorable outcome than NI-LABC and needs close follow-up.
