Together, these findings suggest that BMI is associated with blood DNA methylation at a large number of CpGs across the genome, several of which are located in or near genes involved in ATP-binding cassette transportation, tumour necrosis factor signalling, insulin resistance and lipid metabolism.
PurposeLittle is known about the occurrence, timing and prognostic factors for first and also subsequent local (LR), regional (RR) or distant (DM) breast cancer recurrence. As current follow-up is still consensus-based, more information on the patterns and predictors of subsequent recurrences can inform more personalized follow-up decisions.MethodsWomen diagnosed with stage I-III invasive breast cancer who were treated with curative intent were selected from the Netherlands Cancer Registry (N = 9342). Extended Cox regression was used to model the hazard of recurrence over ten years of follow-up for not only site-specific first, but also subsequent recurrences after LR or RR.ResultsIn total, 362 patients had LR, 148 RR and 1343 DM as first recurrence. The risk of first recurrence was highest during the second year post-diagnosis (3.9%; 95% CI 3.5–4.3) with similar patterns for LR, RR and DM. Young age (<40), tumour size >2 cm, tumour grade II/III, positive lymph nodes, multifocality and no chemotherapy were prognostic factors for first recurrence. The risk of developing a second recurrence after LR or RR (N = 176) was significantly higher after RR than after LR (50 vs 29%; p < 0.001). After a second LR or RR, more than half of the women were diagnosed with a third recurrence.ConclusionsAlthough the risk of subsequent recurrence is high, absolute incidence remains low. Also, almost half the second recurrences are detected in the first year after previous recurrence and more than 80% are DM. This suggests that more intensive follow-up for early detection subsequent recurrence is not likely to be (cost-)effective.Electronic supplementary materialThe online version of this article (doi:10.1007/s10549-017-4340-3) contains supplementary material, which is available to authorized users.
Objective The purpose of this study was to explore differences in sedentary behavior, length of hospital stay, and discharge destination of patients before and after the Ban Bedcentricity implementation at ward-level. Methods The Ban Bedcentricity innovation and implementation procedure were implemented at the cardiothoracic surgery, cardiology, and orthopedics-traumatology wards. Sedentary behavior data were collected 2 weeks before and after the implementation using behavioral observations and analyzed with Pearson’s chi-square. Length of hospital stay and discharge destination data were collected from all admitted patients and analyzed with multiple and logistic regression analyses. Results Behavioral observations showed that in 52% of the observations patients were lying in bed before implementation and 40% after implementation at the cardiothoracic surgery, 64% and 46% at the cardiology, and 53% and 57% at the orthopedics-traumatology wards. The mean length of hospital stay after implementation (compared to before implementation) was 5.1 days at the cardiothoracic surgery (n = 1923; mean + +0.13 days; 95%CI = −0.32 to +0.60), 2.6 days at the cardiology (n = 2646; mean = −0.22 days; 95%CI = −0.29 to −0.14), and 2.4 days at the Orthopedics-Traumatology wards (n = 1598; mean = +0.28 days = 95%CI = +0.06 to +0.50). After the implementation, more patients were discharged home from the cardiothoracic surgery (odds ratio [OR = 1.23]; 95%CI = 1.07 to 1.37) and cardiology wards (OR = 1.37; 95%CI = 1.22 to 1.49), and no statistically significant difference was found at the orthopedics-traumatology ward (OR = 1.09; 95%CI = 0.88 to 1.27). Conclusions The outcomes indicate beneficial outcomes after the implementation with less sedentary behavior and proportionately more patients being discharged home, compared to before the implementation. However, little information is available about the adoption and fidelity of Ban Bedcentricity, therefore, outcomes should be interpreted with caution. Impact This multifaceted innovation to reduce sedentary behavior of patients during the hospital stay seems to be promising, with outcomes indicating less sedentary behavior in patients and more patients being discharged home after the implementation.
12074 Background: Female Hodgkin lymphoma (HL) survivors treated with chest radiotherapy (RT) at a young age have a strongly increased risk of breast cancer (BC). Recently concern has been raised that anthracyclines may also increase BC risk, based on studies in childhood cancer survivors with/without a history of chest RT. So far, the association between anthracyclines and BC risk has not been examined in cancer survivors treated at adolescent/adult ages. Now that RT dose and volumes are decreasing, the potential contribution of anthracyclines to BC risk is an important issue. Methods: We assessed BC risk in a cohort of 2314 female 5-year HL survivors, treated at ages 15-50 years and diagnosed between 1965 and 2008 in 20 Dutch hospitals. Treatment factors were time-dependently included in the analysis, focusing on the effect of anthracycline exposure on BC risk. Results: After a median follow-up of 18.8 years, 258 women developed invasive BC or ductal carcinoma in situ as a subsequent malignancy. The 30-year cumulative incidence was 15.0% (95% Confidence Interval (CI) 12.8-17.4%). Mantle field RT (or other RT involving both axillae) was associated with increased risk of BC (Hazard ratio (HR) 1.9; 95% CI 1.2-2.8) compared to no supradiaphragmatic RT or RT to the neck only (Table 1). Gonadotoxic treatment (>4.2 g/m2 procarbazine or pelvic RT) significantly decreased this risk. In a multivariable analysis, anthracycline exposure was associated with increased BC risk (HR 1.8; 95% CI 1.3-2.5) in patients who received a cumulative dose of >200 mg/m2. Among patients exposed to gonadotoxic treatment, the HR of BC associated with >200mg/m2 anthracyclines was 3.8 (95% CI 2.0-7.2), with a trend for higher risk with higher anthracycline dose (HR 1.58 per 100mg/m2 anthracycline, p<0.001). Conclusions: Our results suggest an association of anthracyclines with BC risk in HL survivors. Also when accounting for the protective effect of gonadotoxic treatment on RT-associated BC risk, anthracyclines significantly contributed to a higher BC risk.[Table: see text]
