Purpose: The protective effect of Allium vegetables against carcinogenesis has been reported in experimental studies particularly focusing on the gut. Therefore, we conducted a hospital-based matched case-control study to explore the association between dietary Allium consumption and risk of breast cancer among Iranian women in northwest Iran. Methods: A validated, quantitative, food frequency questionnaire was completed in 285 women (aged 25–65 years old) newly diagnosed with histopathologically confirmed breast cancer (grade II, III or clinical stage II, III) in Tabriz, northwest Iran, and the completed questionnaires were included in an age- and regional-matched hospital based-control study. The odds ratios (ORs) and 95% confidence intervals (95% CI) were estimated using conditional logistic regression models. Results: Multivariate analysis showed that there was a negative association between the consumption of raw onion and risk of breast cancer after adjustment for covariates (OR, 0.63; 95% CI, 0.40–1.00); however, this association was insignificant. On the other hand, there was a positive association between consumption of cooked onion and risk of breast cancer, after adjustment for covariates (OR, 1.54; 95% CI, 1.02–2.32). However, reduced risk of breast cancer was associated with higher consumption of garlic and leek with adjusted ORs of 0.41 (95% CI, 0.20–0.83) and 0.28 (95% CI, 0.15–0.51), respectively. Conclusion: Our findings suggest that high consumption of certain Allium vegetables, in particular garlic and leek, may reduce the risk of breast cancer, while high consumption of cooked onion may be associated with an increased risk of breast cancer.

Background: A protective effect of resistant starch (RS) containing foods on carcinogenesis has been shown from several lines of experimental evidence for gastrointestinal cancers. Therefore, we aimed to investigate the association between RS contained foods and breast cancer (BC) risk in a hospital-based, age- and origin-matched, case-control study. Materials and Methods: A validated, semi-quantitative, food frequency questionnaire (FFQ) was completed by 306 women newly diagnosed with BC aged 25 to 65 years, and 309 healthy women as matched controls. Odds ratios (ORs) and 95% confidence intervals (95%CI) were estimated using conditional logistic regression models. Results: Reduced BC risk was associated with the highest tertile of whole-wheat bread and boiled potato consumption with adjusted ORs at 0.34 (95%CI: 0.19-0.59) and 0.61 (95%CI: 0.37-0.99), respectively. Among consumers of whole-wheat bread, the protective role of cereals remained relatively apparent at higher intakes level of fiber rich breads at adjusted models (OR=0.53, 95%CI: 0.28-1.01). Moreover, high intake of legumes was found out to be a significant protective dietary factor against risk of BC development with an OR of 0.01 (95%CI: 0.03-0.13). However, consumption of white bread and biscuits was positively related to BC risk. Conclusions: Our results show that certain RS containing foods, in particular whole wheat bread, legumes and boiled potato may reduce BC risk, whereas higher intake of white bread and biscuits may be related to increased BC risk.

Due to lack of sufficient data on characteristics of breast cancer patients and risk factors for developing metastasis in Iran this study was designed to understand clinical aspects impacting on survival. A cross-sectional study on breast cancer patients was conducted in an oncology clinic of the university hospital between 1995 and 2010. Data were retrieved from medical records and included age, menopausal status, tumor diameter, number of involved nodes, histopathological type, estrogen and progesterone receptor expression, c-erbB-2, primary and secondary metastasis sites, overall survival, disease free interval and type of chemotherapy protocol. The results were analyzed with SPSS 13 software. The mean age of the patients was 49.2 (27-89) years. The primary tumors were mainly ER positive (48%) and PR negative (49.3%). The status of lymph nodes dissected and examined in these patients was unknown in 19 patients (25.3%) while 18 patients (24%) had positive lymph nodes with no report on the number of involved nodes. All of the patients had received antracyclin based chemotherapy in an adjuvant or metastatic setting. Adjuvant hormonal therapy was administered to receptor positive patients. In average, overall survival after recurrence was 30 months (95%CI 24.605-35.325) for non-skeletal versus 42 months (95%CI 31.211-52.789) for skeletal metastasis (P= 0.002). The median survival was also greater for receptor positive patients; 39 months (95%CI 33.716-44.284) for PR+ versus 26 months (95%CI 19.210-32.790) for PR- (P=0.047) and 38 months (95%CI 32.908-43.092) for ER+ versus 27 months (95%CI 18.780-35.220) for ER- patients (P=0.016). No relation was found between site of first metastasis and hormone receptor, age, tumor diameter, DFI and menopausal status. Sites of metastasis were independent of age, size of the tumor, menopausal and hormone receptor status in this study. Overall survival provided significant relations with respect to receptor status and bone metastasis.

Background: Breast cancer is the most frequently occurring cancer among Iranian women; however limited studies have been conducted to address survival rates. Objective: The objective was to examine survival rates in Tabriz (Northwest of Iran) and comparing with those of data reported from other cities and countries. Methods: Survival rates were calculated for one, three, five, seven and ten years for 271 breast cancer patients referred to one university clinic during 1997-2008. Results: Survival analysis demonstrated a lower survival rate compared to western countries. Conclusions: Survival rates for our patients are similar/better than other cities in Iran, but lower than certain European countries and the US. Further studies with a higher number of patients are now required.

Background Interstitial lung disease (ILD) includes a heterogeneous group of disease entities. Idiopathic pulmonary fibrosis (IPF) is ultimately fatal, and accurate diagnosis of IPF is critical to clinical decision making. Visual interpretation of chest high resolution CT (HRCT) is subjective and has limited reproducibility, especially with early disease. So we have previously developed attention-gated deep learning algorithm to diagnosis IPF and machine learning to predict IPF progression. The overall aim of IS-IPF is to collect the data from two centers of excellence and evaluate the robustness of the algorithm. We present the preliminary data of the patients studied following disease classification by the multidisciplinary review committees (MDCs) at UCLA and Asan Medical Center (AMC). Methods The IS-IPF study plans to include 234 IPF and 266 non-IPF cases from two large ILD centers (UCLA and AMC). Eligible patients were evaluated in ILD MDC, were >18 years old, had a HRCT, pulmonary function testing, and a committee diagnosis of IPF or non-IPF. Relevant demographic information was collected from the medical record. Results Total 185 IPF and 266 non-IPF patients’ HRCT images have been collected in the IS-IPF study. By center, 51 IPF and 133 non- IPF patients’ HRCT were collected from UCLA, and 134 IPF and 133 non-IPF patients’ HRCT were collected from AMC. On MDC diagnosis, non-IPF cohorts consisted of 33% hypersensitivity pneumonitis, and 67% other connective tissue disease-ILD. Mean age was 61 years (63 IPF and 58 non-IPF), and 63% were male (82% IPF and 57 % non-IPF). Up to date, the predicted FVC was 74.7% and the predicted DLco was 61.6 % in the IPF cohort. Data collection is on-going. Conclusions These well-characterized cohorts will be used to evaluate HRCT image signatures for distinguishing IPF from other ILD, and predicting patient-specific IPF progression within 2 years of diagnosis.
