Neuroblastoma is one of the most commonly diagnosed extracranial solid tumors in infancy; however, the etiology of neuroblastoma remains largely unknown. Previous genome-wide association study (GWAS) indicated that several common genetic variations (rs110419 A > G, rs4758051 G > A, rs10840002 A > G and rs204938 A > G) in the LIM domain only 1 (LMO1) gene were associated with neuroblastoma susceptibility. The aim of this study was to evaluate the correlation between the four GWAS-identified LMO1 gene polymorphisms and neuroblastoma risk in a Southern Chinese population. We genotyped the four polymorphisms in 256 neuroblastoma cases and 531 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the strength of the associations. False-positive report probability was calculated for all significant findings. We found that the rs110419 A > G polymorphism was associated with a significantly decreased neuroblastoma risk (AG vs. AA: adjusted OR = 0.65, 95% CI = 0.47–0.91; GG vs. AA: adjusted OR = 0.58, 95% CI = 0.36–0.91; AG/GG vs. AA: adjusted OR = 0.63, 95% CI = 0.46–0.86), and the protective effect was more predominant in children of age > 18 months, males, subgroups with tumor in adrenal gland and mediastinum, and patients in clinical stages III/IV. These results suggested that LMO1 gene rs110419 A > G polymorphism may contribute to protection against neuroblastoma. Our findings call for further validation studies with larger sample size.
Background
To compare the efficacy of total and conventional laparoscopic hepaticojejunostomy (TLH and CLH) in children with choledochal cysts (CDCs).
Methods
Data from patients undergoing TLH and CLH between August 2017 and December 2018 were retrospectively analyzed. Intraoperative blood loss, time for jejunum-cojejunum anastomosis, time to oral intake, postoperative hospital stay, hospitalization expenses, and postoperative complications were compared.
Results
All 55 patients (TLH = 30, CLH = 25) were successfully treated without conversion to open surgery. In the TLH and CLH groups, the time to oral intake was 3.57 ± 0.19 d and 4.56 ± 0.27 d, respectively (t = 3.07, P < 0.01), the postoperative hospital stay was 5.50 ± 0.28 d and 7.00 ± 0.74 d (t = 2.03, P < 0.05), and the hospitalization expenses were CNY 40,085 ± 2447 and CNY 26,084 ± 2776 (t = 3.79, P < 0.001). There were no significant differences in intraoperative blood loss (9.57 ± 3.28 ml vs 8.2 ± 1.13 ml, t = 0.37, P = 0.72) or time for jejunum-cojejunum anastomosis (80.5 ± 2.46 min vs 75.00 ± 2.04 min, t = 1.68, P = 0.10). The median follow-up periods of the TLH and CLH groups were 17 and 16 months, respectively. Overall complication rates were comparable between the two groups (10% vs 8%, χ2 = 0.07, P = 0.79).
Conclusions
TLH in children with CDCs has the advantages of rapid gastrointestinal functional recovery and a short hospitalization. However, hospitalization is relatively expensive.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
