Cross-Sectional Study on MRI Restaging After Chemoradiotherapy and Interval to Surgery in Rectal Cancer: Influence on Short- and Long-Term Outcomes

Background. The time interval between CRT and surgery in rectal cancer patients is still the subject of debate. The aim of this study was to first evaluate the nationwide use of restaging magnetic resonance imaging (MRI) and its impact on timing of surgery, and, second, to evaluate the impact of timing of surgery after chemoradiotherapy (CRT) on short- and long-term outcomes. Methods. Patients were selected from a collaborative rectal cancer research project including 71 Dutch centres, and were subdivided into two groups according to time interval from the start of preoperative CRT to surgery (= 14 weeks), and the long-interval group included a higher proportion of cT4 stage and multivisceral resection patients. Pathological complete response rate (n = 34 [15.2%] vs. n = 47 [18.7%], p = 0.305) and CRM involvement (9.7% vs. 15.9%, p = 0.145) did not significantly differ. Thirty-day surgical complications were similar (20.1% vs. 23.1%, p = 0.943), however no significant differences were found for local and distant recurrence rates, disease-free survival, and overall survival. Conclusions. These real-life data, reflecting routine daily practice in The Netherlands, showed substantial variability in the use and timing of restaging MRI after preoperative CRT for rectal cancer, as well as time interval to surgery. Surgery before or after 14 weeks from the start of CRT resulted in similar short- and long-term outcomes

Decrease in foetal and neonatal mortality in the Netherlands; comparison with other Euro-Peristat countries in 2004, 2010 and 2015

OBJECTIVE: To compare changes in foetal, neonatal and perinatal mortality in the Netherlands in 2015, relative to 2004 and 2010, with changes in other European countries and regions. DESIGN: Descriptive population-wide study. METHOD: Data from 32 European countries and regions within the Euro-Peristat registration area were analysed. These countries and regions were grouped into: the Netherlands, Scandinavia, Western Europe and Eastern Europe. International differences in registration and policies were taken into account by using rates from 28 weeks gestation for foetal mortality and for 24 weeks gestation and beyond for neonatal mortality. Ranking was based on individual countries and regions. RESULTS: Foetal mortality decreased by 24% in the Netherlands, from 2.9 per 1,000 births in 2010 to 2.2 per 1,000 births in 2015; neonatal mortality decreased by 9%, from 2.2 to 2.0 per 1,000 live births. Perinatal mortality (the sum of foetal mortality and neonatal mortality) decreased by 18% from 5.1 to 4.2 per 1,000 births. The Netherlands moved from the 18th place in the European ranking in 2004 to the 10th place in 2015. CONCLUSION: Foetal, neonatal and perinatal mortality in the Netherlands decreased in 2015 when compared with 2004 and 2010. The country's position in the European ranking also improved. Explanations for this decrease are related to changes in the areas of organisation of care, population and risk factors. When mortality rates in other European countries and regions - particularly Scandinavia - are considered there is room for further improvement

Survival and causes of death in extremely preterm infants in the Netherlands

Objective In the Netherlands, the threshold for offering active treatment for spontaneous birth was lowered from 25 +0 to 24 +0 weeks' gestation in 2010. This study aimed to evaluate the impact of guideline implementation on survival and causes and timing of death in the years following implementation. Design National cohort study, using data from the Netherlands Perinatal Registry. Patients The study population included all 3312 stillborn and live born infants with a gestational age (GA) between 24 0/7 and 26 6/7 weeks born between January 2011 and December 2017. Infants with the same GA born between January 2007 and December 2009 (N=1400) were used as the reference group. Main outcome measures Survival to discharge, as well as cause and timing of death. Results After guideline implementation, there was a significant increase in neonatal intensive care unit (NICU) admission rate for live born infants born at 24 weeks' GA (27%-69%, p<0.001), resulting in increased survival to discharge in 24-week live born infants (13%-34%, p<0.001). Top three causes of in-hospital mortality were necrotising enterocolitis (28%), respiratory distress syndrome (19%) and intraventricular haemorrhage (17%). A significant decrease in cause of death either complicated or caused by respiratory insufficiency was seen over time (34% in 2011-2014 to 23% in 2015-2017, p=0.006). Conclusions Implementation of the 2010 guideline resulted as expected in increased NICU admissions rate and postnatal survival of infants born at 24 weeks' GA. In the years after implementation, a shift in cause of death was seen from respiratory insufficiency towards necrotising enterocolitis and sepsis
