ABSTRACT

INTRODUCTION: Serum albumin (Alb) levels have been found to be independent predictors of all-cause mortality in a community-based population, but whether this is the case for serum cholinesterase (ChE) levels is uncertain. This study aimed to determine whether serum ChE levels are independent predictors of all-cause mortality in a community-based population. METHODS: A total of 3,504 subjects (mean age 62.5 years) from Takahata, Japan, participated and were followed up for 13.5 years (median 13.2 years). Based on baseline serum Alb and ChE levels, subjects were stratified by interquartile range as low, middle, and high. The correlation between serum Alb and ChE levels was examined by calculating correlation coefficients. The association between each group and all-cause mortality was examined by Kaplan-Meier and Cox proportional hazards analyses. RESULTS: During follow-up, 568 subjects died. There was a positive correlation between serum Alb and ChE levels (r = 0.30). Kaplan-Meier analysis showed that all-cause mortality in the low group was significantly higher for both serum Alb and ChE levels (log-rank p < 0.01). Adjusted Cox proportional hazards analysis showed that the serum Alb level was not an independent predictor of all-cause mortality (hazard ratio [HR] 1.18, 95% confidence interval [CI], 0.95-1.46 for all-cause mortality in the low group compared to the middle group), whereas the serum ChE level was an independent predictor of all-cause mortality (HR 1.30, 95% CI, 1.06-1.59 for all-cause mortality in the low group compared to the middle group). CONCLUSION: The serum ChE level is an independent predictor of all-cause mortality in the general community-based population.

ABSTRACT

Objective: In this study, we provide long-term outcome data of patients with primary central nervous system lymphoma. Methods: The long-term outcomes of PCNSL patients diagnosed between 1982 and 2006 were reviewed. Neurological late neurotoxicity symptoms, neuroradiological brain atrophy and leukoencephalopathy were evaluated. Surviving patients completed the Quality of Life Questionnaire-30 and Brain Cancer Module-20. The differences in overall survival were assessed using the Kaplan-Meier method and log-rank test. The differences between groups in terms of each investigated parameter were analyzed using the Wilcoxon signed-rank test. Results: Among 112 PCNSL patients, there were 33 (29.4%) long-term (> 5 years) survivors. The median survival of all long-term survivors was 105.7 months; of these, 8 (7.1%) were alive at the latest follow-up, with a mean survival time of 170.2 months (range, 121.8­286.4). Clinical assessment revealed severe neurotoxicity in 14 patients (42.4%), moderate neurotoxicity in 5 (15.1%), and normal status in 14 (42.4%). Correlations were seen between the neuroradiological imaging score changes and neurocognitive condition (P=0.0001), neurocognitive condition and the whole brain irradiation dose (P=0.0004), and atrophy and the whole brain irradiation dose (P=0.0035). Conclusions: A more severe clinical condition was found to be associated with increasing age and whole brain irradiation dose in long-term survivors with PCNSL.
