RESUMO

BACKGROUND/AIMS: High-quality colonoscopy is essential to reduce colorectal cancer-related deaths. Little is known about colonoscopy quality in non-academic practice settings. We aimed to evaluate the quality of colonoscopies performed in community hospitals and nonhospital facilities. METHODS: Colonoscopy data were collected from patients referred to six tertiary care centers after receiving colonoscopies at community hospitals and nonhospital facilities. Based on their photographs, we measured quality indicators including cecal intubation rate, withdrawal time, adequacy of bowel preparation, and number of polyps. RESULTS: Data from a total of 1,064 colonoscopies were analyzed. The overall cecal intubation rate was 93.1%. The median withdrawal time was 8.3 minutes, but 31.3% of colonoscopies were withdrawn within 6 minutes. Community hospitals had longer withdrawal time and more polyps than nonhospital facilities (median withdrawal time: 9.9 minutes vs. 7.5 minutes, p < 0.001; mean number of polyps: 3.1 vs. 2.3, p = 0.001). Board-certified endoscopists had a higher rate of cecal intubation than non-board-certified endoscopists (93.2% vs. 85.2%, p = 0.006). A total of 819 follow-up colonoscopies were performed at referral centers with a median interval of 28 days. In total, 2,546 polyps were detected at baseline, and 1,088 were newly identified (polyp miss rate, 29.9%). Multivariable analysis revealed that older age (odds ratio [OR], 1.032; 95% confidence interval [CI], 1.020 to 1.044) and male sex (OR, 1.719; 95% CI, 1.281 to 2.308) were associated with increased risk of missed polyps. CONCLUSION: The quality of colonoscopies performed in community hospitals and nonhospital facilities was suboptimal. Systematic reporting, auditing, and feedback are needed for quality improvement.

RESUMO

This study investigated the outcomes of allogeneic hematopoietic cell transplantation (allo-HCT) in acute myeloid leukemia (AML) patients with monosomal karyotypes (MK). A total of 114 AML patients who received allo-HCT were retrospectively analyzed. At the time of diagnosis, 13 patients were categorized with a favorable cytogenetic risk, 78 with an intermediate risk, and 23 with an adverse risk. MK was found in 12 patients among 23 with adverse cytogenetic risk. Pretransplant disease status was active disease in 5 cases (45.5%) in the adverse-risk without MK group, and 8 cases (66.7%) in the corresponding group with MK, 15 (19.2%) in the intermediate group and 4 (30.8%) in the favorable group. In multivariate analysis, active disease before transplant (hazard ratio, HR 3.913, p < 0.001), acute graft-versus-host disease (GVHD) ≥grade 2 (HR 1.908, p = 0.048) and chronic GVHD (HR 0.364, p = 0.001) affected overall survival (OS). The initial cytogenetic risk groups were not a significant risk factor for OS in allogeneic settings. The 2-year OS rate was 44.0 ± 15.9% without MK and 20.7 ± 17.9% with MK (p = 0.246). However, the OS rate was better for patients with chronic GVHD (p = 0.025). In conclusion, a survival benefit was observed for MK-positive patients with chronic GVHD in an allogeneic setting. However, the prognosis still remained poor for patients with MK.
