Octogenarians are more often viewed as high-risk surgical candidates. This increased risk is attributed to an age-related decline in physical function and reserve capacity coupled with the presence of various underlying diseases. There are no current guidelines or consensus on the optimal treatment strategy for this cohort of complex patients. The aim of this systematic review and meta-analysis was to compare the efficacy and safety of laparoscopic colorectal resection versus open colorectal resection in octogenarians. The meta-analysis was conducted following all aspects of the Cochrane Handbook for Systematic Reviews and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A systematic literature review was carried out using the following databases: MEDLINE, Embase, PubMed, the Cochrane Library, Google Scholar and OVID. Only studies comparing outcome of laparoscopic and open colorectal resections in the elderly population (≥80 years) were selected. The data collected included the patient demographics, interventions, observed outcome and sources of bias. When performing the statistical analysis, we used the odds ratio for categorical variables and the weighted mean difference for continuous variables. The results of this systematic review and pooled analysis demonstrated the safety and potential benefits of laparoscopic colorectal resection in octogenarians. LC can reduce the length of hospital stay, intraoperative blood loss, time to return of normal bowel function, and incidence of postoperative pneumonia, wound infection, and postoperative ileus.
Background:To investigate the association between fasting blood glucose (FBG) levels and the risk of incident primary liver cancer (PLC) in Chinese males, a large prospective cohort was performed in the current study.Methods:A total of 109 169 males participating in the routine checkups every two years were recruited in the Kailuan male cohort study since May 2006. Cox proportional hazards regression models and restricted cubic spline (RCS) were used to evaluate the association between levels of baseline FBG and the risk of incident PLC.Results:Compared to the males with normal FBG (3.9⩽FBG<6.1 mmol l−1), the males with impaired fasting glucose (IFG: 6.1⩽FBG<7.0 mmol l−1) and diabetes mellitus (DM: FBG ⩾7.0 mmol l−1) had a 60% (95% CI: 1.09–2.35) and a 58% (95% CI: 1.07–2.34) higher risk of incident PLC, respectively. Subgroup analysis found that IFG increased the risk of PLC among the non-smoker (HR=1.73, 95% CI: 1.01–2.98) and current alcohol drinker (HR=1.80, 95% CI: 1.03–3.16). While DM increased the risk of PLC especially among the males with normal BMI (<25 kg m−2) (HR=1.76, 95% CI: 1.05–2.94) and the HBV negativity (HR=1.89, 95% CI: 1.16–3.09), RCS analysis showed a positive non-linearly association between the FBG levels and the risk of PLC (p-overall=0.041, p-non-linear=0.049).Conclusions:Increased FBG may be an important and potentially modifiable exposure that could have key scientific and clinical importance for preventing PLC development.
Objective
The main aim of this study was to investigate the association of polymorphisms in long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) with the risk of esophageal squamous cell carcinoma (ESCC) in a Chinese population.
Methods
A total of 245 ESCC patients and 490 gender- and age-matched cancer-free controls were genotyped for four tag single nucleotide polymorphisms (SNPs) of MALAT1 (rs3200401 C > T, rs1122709 C > G, rs664589 C > G, and rs619586 A > G). Statistical analyses including chi-squared test and logistic regression were performed to identify the association between the tag SNPs and risk of ESCC, and false discovery rate (FDR) <25% was applied to adjust for multiple comparisons.
Results
We found that rs3200401 C > T polymorphism of MALAT1 was significantly associated with increased risk of ESCC (CT vs CC: adjusted OR =1.59, 95% CI =1.07–2.35,
P
=0.021; TT vs CC: adjusted OR =2.27, 95% CI =1.04–4.96,
P
=0.039; dominant model [CT+TT vs CC]: adjusted OR =1.68, 95% CI =1.16–2.43,
P
=0.006). In the stratified analysis, rs3200401 TT and CT/TT genotypes were associated with increased risk of ESCC compared with CC genotype in subgroup of never drinking (TT vs CC: adjusted OR =2.34, 95% CI =1.02–5.34,
P
=0.044; CT/TT vs CC: adjusted OR =1.52, 95% CI =1.02–2.26,
P
=0.041). However, compared with AA genotype, MALAT1 rs619586 GG was associated with decreased risk of ESCC in ever drinking subgroup (GG vs AA: adjusted OR =0.38, 95% CI =0.15–0.99,
P
=0.049). The results remained significant after FDR adjustment (FDR value <0.25) except for the comparison between rs619586 GG and AA genotype in ever drinking subgroup.
Conclusion
Taken together, our findings proposed that polymorphism rs3200401 C > T in MALAT1 gene is associated with increased risk of ESCC. Since the association between rs619586 A > G polymorphism and ESCC risk was not significant after FDR adjustment, there was a minor possibility that rs619586 A > G might be a protective factor for ESCC.
