Prophylactic and ongoing use of topical betamethasone 0.1% during chest wall RT for breast cancer delays occurrence of ARD but does not prevent it. Petrolatum has no effect on the prevention of ARD in these patients.
Objective: We conducted a hospital-based, case-control study to examine the association between dietary patterns and the risk of oesophageal squamous cell carcinoma in Iran. Design: A total of forty-seven patients with oesophageal squamous cell carcinoma and ninety-six controls underwent face-to-face interviews. Factor analysis was used to detect dietary patterns. Multivariate logistic regression was used to estimate OR and 95 % CI. Results: We defined two major dietary patterns in this population: 'healthy diet' (high in vegetables, nuts, fruits, low-fat dairy and fish) and 'western diet' (high in solid oil, sugar, sweets, tea, eggs, pickles and processed meat). Both healthy and western pattern scores were divided into two categories (based on medians). Higher healthy pattern scores were significantly associated with decreased risk of oesophageal squamous cell carcinoma (high: second median v. low: first median, OR 5 0?17, 95 % CI 0?19, 0?98). An increased risk of oesophageal squamous cell carcinoma was observed with the western pattern (high: second median v. low: first median, OR 5 10? 13, 95 % CI 8?45, 43?68). Conclusions:The results of the present study suggested that diet might be associated with oesophageal carcinoma.
Breast cancer is a major cause of morbidity and cancer related mortality among women. The prevalence of breast cancer was reported as increasing in most of the Asian countries (Aini abdullah et al., 2013;Najafi et al., 2013). Iran is also sharing the same experience. The etiology of breast cancer is largely unknown; therefore there is no established primary prevention strategy. So, the main strategy is the establishment of screening protocols and early detection programs, which at least theoretically can improve the survival rates. Despite the increasing incidence, the survival rates of breast cancer patients in many developed countries were substantially improved. According to national cancer registry project report, breast cancer is the most common cancer and also the most common cause of cancer-related deaths of female population in Iran (Mohagheghi et al., 2009).According to international agency for research on
<b><i>Introduction:</i></b> Radiation dermatitis (RD) is a side effect of radiation therapy (RT) which is experienced by over 90% of patients being treated for breast cancer. The current clinical trial was conducted to measure the preventative effects of a boron-based gel on several different clinical outcomes (dermatitis, erythema, dry desquamation, and moist desquamation) after 25 radiotherapy sessions. <b><i>Methods:</i></b> This research used a double-blind parallel-group design with a placebo control (<i>n</i> = 76) and randomized group (<i>n</i> = 181), with all participants being between 18 and 75 years old. Fifteen minutes before each radiotherapy, participants in the intervention group were given a gel containing 3% sodium pentaborate pentahydrate, while those in the placebo group received a gel with no chemical substance. Dermatitis, erythema, dry desquamation, and moist desquamation were compared between the 2 groups. <b><i>Results:</i></b> At baseline, there were no significant differences between the groups (<i>p</i> > 0.05), except for body mass index. After 14 days of treatment, dermatitis (98.7% vs. 9.9%; <i>p</i> < 0.001), erythema (96.1% vs. 12.2%; <i>p</i> < 0.001), dry desquamation (50% vs. 3.9%; <i>p</i> < 0.001), and moist desquamation (18.4% vs. 0.6%; <i>p</i> < 0.001) were much more common in the placebo group than the intervention group. To prevent dermatitis, erythema, dry desquamation, and moist desquamation in 1 patient, on average, 1.1 (95% confidence interval [CI]: 1.1–1.2), 1.2 (95% CI: 1.1–1.3), 2.2 (95% CI: 1.7–2.9), and 5.6 (95% CI: 3.8–11.0) patients need to be treated, respectively. <b><i>Conclusion:</i></b> The boron-based gel has a significant preventive effect on several categories of RD which might be used by clinicians in breast cancer.
AIM: Cancer treatments specially with new high Tec radiotherapy equipment's calling daily progression in method and predictive factors affecting treatment goals. Due to important effect of oxygen on cells radio sensitivity, tumor blood circulation and it's antigens like ABO blood groups maybe an important predictive factor for radiotherapy response and it is adverse events. The aim of this study was the assessment of the hematological manifestations of local radiotherapy and association with ABO blood groups. METHODS: In this observational study, 2 ml of peripheral blood were taken from 152 patients with routine 3D conformal radiotherapy treatment course and the blood parameters achieve and documented at four stage during treatment courses. The data were analyzed by repeated measurement andone-way ANOVA. RESULTS: Statistically signifi cant reductions of the platelets, white blood cells (WBC), and lymphocytes counts were demonstrated. Also an increased percentage of polymorphonuclear cells during local radiotherapy exposure was found. The changes in WBC counts were observed to be in association with ABO blood groups. The other evaluated factors were not signifi cantly associated with ABO blood groups. CONCLUSIONS: Our results showed an association between radiotherapy patients ABO blood groups and some hematological changes in their blood circulation (Fig. 7, Ref. 23).
