The effect of age on survival after endoscopic resection versus surgery for T1a esophageal cancer.

ABSTRACT: BACKGROUND:Endoscopic resection has emerged as a treatment option for T1a esophageal cancer, but the impact of age on patient selection for surgery versus endoscopic resection has not been well studied. We hypothesized that endoscopic resection would be associated with improved survival compared with surgery in older patients with early esophageal cancer and worse survival in younger patients. METHODS:The National Cancer Database was used to identify patients with cT1aN0M0 esophageal cancer (2010-2015) treated with endoscopic resection or esophagectomy. The relationship between age and treatment effect on survival was modeled with an interaction term in a Cox proportional hazards regression. The primary outcome was overall survival. RESULTS:A total of 831 patients met study criteria: A total of 448 patients (54%) underwent endoscopic resection, and 383 patients (46%) underwent esophagectomy. In a multivariable Cox model, the interaction term between patient age and type of treatment was nonsignificant (P = .11), suggesting that age did not influence the effect of endoscopic resection compared with surgery on survival. In 285 propensity score-matched patients receiving endoscopic resection or surgery, surgery was associated with similar survival compared with endoscopic resection (hazard ratio, 1.40; 95% confidence interval, 0.97-2.03). CONCLUSIONS:Endoscopic resection was associated with similar survival compared with surgery in patients with cT1a esophageal cancer regardless of age. Endoscopic resection can be considered for patients at low risk of nodal involvement across all age groups as an alternative to surgery for T1a esophageal cancer.

Project description:BackgroundEsophagectomy for esophageal cancer is associated with a substantial risk of life-threatening complications and a limited long-term survival. This study aimed to clarify the controversial questions of how age influences short-term and long-term survival.MethodsThis population-based cohort study included almost all patients who underwent curatively intended esophagectomy for esophageal cancer in Sweden in 1987-2010, with follow-up through 2016. The exposure was age, analyzed both as a continuous and categorical variable. The probability of mortality was computed using a novel flexible parametric model approach. The reported probabilities are proper measures of the risk of dying, and the related odds ratios (OR) are therefore more suitable measures of association than hazard ratios. The outcomes were 90-day all-cause mortality, 5-year all-cause mortality, and 5-year disease-specific mortality. A novel flexible parametric model was used to derive the instantaneous probability of dying and the related OR along with 95% confidence intervals (CIs), adjusted for sex, education, comorbidity, tumor histology, pathological tumor stage, and resection margin status.ResultsAmong 1737 included patients, the median age was 65.6 years. When analyzed as a continuous variable, older age was associated with slightly higher odds of 90-day all-cause mortality (OR 1.05, 95% CI 1.02-1.07), 5-year all-cause mortality (OR 1.02, 95% CI 1.01-1.03), and 5-year disease-specific mortality (OR 1.01, 95% CI 1.01-1.02). Compared with patients aged < 70 years, those aged 70-74 years had no increased risk of any mortality outcome, while patients aged ≥ 75 years had higher odds of 90-day mortality (OR 2.85, 95% CI 1.68-4.84), 5-year all-cause mortality (OR 1.56, 95% CI 1.27-1.92), and 5-year disease-specific mortality (OR 1.38, 95% CI 1.09-1.76).ConclusionsPatient age 75 years or older at esophagectomy for esophageal cancer appears to be an independent risk factor for higher short-term mortality and lower long-term survival.

Project description:ObjectivesTo investigate the treatment effects of endoscopic submucosal dissection (ESD) versus endoscopic mucosal resection (EMR) for early gastric cancer (EGC).DesignMeta-analysis.MethodsWe systematically searched three electronic databases, including PubMed, EmBase and the Cochrane library for studies published with inception to January 2018. The eligible studies should be evaluated for the efficacy and safety of ESD versus EMR for patients with EGC. The summary ORs and standard mean differences (SMDs) with 95% CIs were employed as effect estimates. Sensitivity analyses were conducted to evaluate the impact of single study on overall analysis. Subgroup analyses were performed for investigated outcomes to evaluate the treatment effects of ESD versus EMR for patients with EGC with specific subsets.ResultsEighteen studies, with a total of 6723 patients with EGC, were included in final analysis. The summary ORs indicated that patients with EGC who received ESD were associated with an increased incidence of en bloc resection (OR: 9.00; 95% CI: 6.66 to 12.17; p<0.001), complete resection (OR: 8.43; 95% CI: 5.04 to 14.09; p<0.001) and curative resection (OR: 2.92; 95% CI: 1.85 to 4.61; p<0.001) when compared with EMR. Furthermore, ESD was associated with lower risk of local recurrence (OR: 0.18; 95% CI: 0.09 to 0.34; p<0.001). In addition, there was no significant difference between ESD and EMR for the risk of bleeding (OR: 1.26; 95% CI: 0.88 to 1.80; p=0.203). Though, ESD was correlated with greater risk of perforation (OR: 2.55; 95% CI: 1.48 to 4.39; p=0.001), and longer operation time (SMD: 1.12; 95% CI: 0.13 to 2.10; p=0.026) as compared with EMR. Additionally, several different features observed in included studies and patients could bias the effectiveness of ESD versus EMR in patients with EGC.ConclusionsESD is superior than EMR for en bloc resection, complete resection, curative resection and local recurrence, while it increased perforation risk and longer operation time.
