Method One thousand seven hundred and six patients with newly diagnosed NPC (1320 from the primary cohort and 386 from the validated cohort) from January 2010 to March 2014 were enrolled. Clinical features and 12 immune-related variables were analyzed. Results A high absolute lymphocyte count (ALC; >3.2 × 109/L) correlated with a poor prognosis of patients with NPC. Significant OS differences were discovered between patients with high ALC and no ALC elevation (p < 0.05, in primary cohort), showing similar prognostic risk to patients with advanced NPC (p > 0.05, in validated cohort). ALC improved the predictive performance of the basic tumor-node-metastasis prognostic model (p = 0.025), which was reliably validated in the external independent cohort. Conclusion High ALC is a surrogate marker for improved prognostic risk stratification in NPC. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Immediate or interval abscess tonsillectomy? A systematic review and meta-analysis

A systematic review and meta-analysis Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Feb 15. doi: 10.1007/s00405-022-07294-x. Online ahead of print. ABSTRACT OBJECTIVES: Peritonsillar abscess is a common complication of acute tonsillitis. However, no consensus has been reached yet on the optimal treatment of this condition. Therefore, this study aimed to compare clinical outcomes of immediate and interval abscess tonsillectomy. METHODS: The databases of PubMed, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for completed studies published until the 1st of November 2021. Comparative studies assessing intraoperative and postoperative outcomes of immediate and interval abscess tonsillectomy were considered, with the primary outcome being postoperative hemorrhage. Operative time, intraoperative blood loss, postoperative pain, and duration of hospital stay were classed as secondary outcomes. A random-effects pairwise meta-analysis of both randomized a nd non-randomized trials was conducted. Subgroup analysis linked to the randomization of trials was executed. Quality assessment was performed, utilizing the Cochrane risk of bias tool and ROBINS-I tool for randomized and non-randomized trials, respectively. RESULTS: Data from 265 cases stemming from six trials were pooled together. For postoperative bleeding rates, no statistically significant difference between immediate and interval tonsillectomy was detected (OR = 1.26; 95% CI 0.27, 5.86; p = 0.77). By contrast, longer hospital stay was observed for patients subjected to interval tonsillectomy (SMD = - 0.78; CI - 1.39 to- 0.17; p = 0.01). For operative time and intraoperative blood loss, no statistically significant difference was noticed between immediate and interval tonsillectomy (SMD = 1.10; 95% CI - 0.13, 2.33; p = 0.08; and SMD = 0.04; 95% CI - 0.49, 0.57; p = 0.88; respectively). CONCLUSIONS: This study shows that quinsy tonsillectomy appears to be a safe meth od, providing full abscess drainage and instant relief of the symptoms. Moreover, quinsy tonsillectomy was not associated with a statistically higher postoperative hemorrhage incidence rate than immediate tonsillectomy.
