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:BackgroundEsophagectomy is still advised as an additional treatment for patients with superficial esophageal cancer (EC, T1a-T1b) after endoscopic resection (ER). However, esophagectomy often deteriorates the general condition of EC patients. In recent years, adjuvant chemoradiotherapy (CRT) has been recognized as a reliable, non-surgical treatment that can improve the prognosis. How to combine ER with adjuvant therapy to bring maximal benefits to patients has become a hot clinical research hot topic. However, the current studies have mostly been conducted retrospectively, in single centers, and with small clinical samples; there have been few prospective and large sample size randomized controlled trials (RCTs). The aim of this systematic review and meta-analysis was to compare the outcomes of adjuvant CRT versus esophagectomy in the treatment of early EC, and to provide a reference for clinical research and practice.MethodsA comprehensive and extensive literature search was performed via the databases of PubMed, Cochrane Library, Embase, and Web of Science online and all randomized cohort studies and retrospective cohort studies were collected. The quality of research was evaluated according to Cochrane's quality standards, and statistical analysis was conducted with Stata 13.0 and RevMan 5.3 software and followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA).ResultsA total of 9 cohort studies, including 790 patients, were included for meta-analysis. The long term effects of the esophagectomy group were better than those of the CRT after ER group [odds ratio (OR) =6.08, 95% confidence interval (CI): 1.96 to 18.84, P=0.002] in disease-free survival (DFS) [hazard ratio (HR) =0.24, 95% CI: 0.07 to 0.85, P=0.03] and overall survival (OS) (HR =1.02, 95% CI: 0.57 to 1.82, P=0.94). Other survival indicators showed no significant difference (P>0.05).ConclusionsThe 2 groups showed no significant results in OS. Although we found that CRT may be suitable for patients with high-risk of relapse or unable to tolerate surgery, it cannot totally replace surgical treatment; further randomized trials are required to verify this view.
