Preoperative neutrophil-to-lymphocyte ratio and plateletto- lymphocyte ratio as new prognostic factors for patients with colorectal cancer.

PURPOSE: The objective of this study was to preoperatively evaluate blood platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) for their prognostic value in patients with colorectal cancer (CRC). METHODS: We retrospectively reviewed 347 patients who underwent colorectal surgery for CRC in the Istanbul Education and Research Hospital and the Antalya Education and Research Hospital. The prognostic value of preoperative PLR, NLR, and other clinical and laboratory parameters was assessed with univariate and multivariate analysis. RESULTS: Median overall survival (OS) was 61.8 months [95% CI for hazard ratio (HR) 46.24-77.14]. Significant parameters in univariate analysis, which were the preoperative levels of carcinoembryonic antigen (CEA) (p=0.055), albumin (p=0.003), hemoglobin (p=0.012), PLR (p=0.004), and NLR (p=0.054) were assessed by multivariate analysis which showed that only albumin retained its significance (p=0.008). Median OS was 70.1 vs 44.8 months with PLR ? 180 vs PLR > 180 (log rank; p=0.005). Median OS was "Not reached" (NR) vs 43.5 months with NLR ? 3 vs NLR > 3 (log rank; p=0.012). CONCLUSIONS: This study showed that preoperative levels of CEA, albumin, PLR, and NLR have significant prognostic value for patients with CRC.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA): Our outcomes from Turkey.

OBJECTIVES: The Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) was described in 2016 and had its case series published. This study aimed to present the largest TOETVA case series performed in Turkey. MATERIAL AND METHODS: Data from 52 patients who underwent TOETVA procedure between February 2018 and October 2019 were analyzed retrospectively. Demographic data, duration of operation, blood loss, rate of conversion to open surgery, radiological findings, pathological outcomes, and complications were analyzed. RESULTS: All patients were female. Mean duration of the operation was 192 ± 45 minutes, mean blood loss was 39 ± 47 mL, and the ratio of surgical site infection was 6% (3/50). In two (4%) patients, TOETVA was converted to open surgery. Temporary and permanent recurrent laryngeal nerve (RLN) paralysis was observed in 2 (4%) and 0 patients, respectively. Temporary and permanent hypoparathyroidism was observed in 10 (20%) and 0 patients, respectively. CONCLUSION: TOETVA procedure is the most recently defined NOTES technique for endocrine surgery. In experienced healthcare centers, TOETVA can achieve outcomes similar and even better than the ones obtained with open surgery. The complication rates, durations of operation, surgical site infection, and blood loss parameters that we observed in our experience are similar to the ones reported in the literature.
