Purpose: Stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) are increasingly used as initial therapies for brain metastases (BM). We aimed to assess the outcomes of SRS/FSRT in patients aged ≥ 65 years who had 1-10 BM from non–small cell lung cancer (NSCLC). Materials and Methods: We retrospectively reviewed 91 elderly NSCLC patients with 222 BM who were treated with SRS/FSRT at two institutions between 2010 and 2020. The primary endpoint was overall survival (OS) after SRS/FSRT. In addition, in-field local control (IFLC) within the treated field was evaluated. Statistical analysis was performed to identify the prognostic factors affecting OS and IFLC. Results: During a median follow-up of 18 months, the median OS was 32 months. The 1- and 2-year survival rates were 69.8% and 56.1%, respectively. In multivariate analysis, the NSCLC-specific graded prognostic assessment (GPA) score (p=0.007) and administration of systemic therapy (p=0.039) were defined as prognosticators affecting OS. The median IFLC period was 31 months, and the 1- and 2-year IFLC rates were 75.9% and 57.6%, respectively. The total BM volume (p=0.042) significantly affected IFLC. No severe adverse events were reported after SRS/FSRT. Conclusion SRS/FSRT is an effective upfront treatment option for BM arising from NSCLC in elderly patients, with a good OS without severe side effects. Higher GPA score and active systemic treatment were associated with improved OS, indicating that elderly patients are significant candidates for SRS/FSRT.

Background: The Controlling Nutritional Status (CONUT) score is an immunonutritional test tool based on serum albumin, total cholesterol, and lymphocyte counts. It has been studied as a simple prognostic predictor for various carcinomas. This study aimed to investigate the association between preoperative CONUT scores and the clinicopathological characteristics in papillary thyroid carcinoma (PTC) patients. Methods: This study included 2,403 PTC patients who underwent total thyroidectomy between 2012 and 2016 at a single tertiary medical center. The CONUT scores were calculated based on preoperative blood tests. The clinicopathological characteristics were retrospectively reviewed. The patients were categorized by the CONUT score (relatively low, 0–2; relatively high, 3–5). Results: Among the 2,997 PTC patients who underwent total thyroidectomy at Pusan National University Hospital between 2012 and 2016, those without preoperative blood test were excluded (n=149). Finally 2,403 patients were analyzed after excluding 439 patients taking lipid-lowering drugs and six patients without available T stage data after surgery. Based on the CONUT score, the relatively high score group had a lower body mass index (23.7±3.3 kg/m2 vs. 21.9±2.9 kg/m2, P<0.001), more advanced T stage (T stage 3/4, 5.9% vs. 11.4%, P=0.045), and higher extrathyroidal extension (2.1% vs. 7.6%, P=0.005). Conclusion Patients included in this large, single-center study all had a preoperative CONUT score of 0–5, but this study demonstrated that higher preoperative CONUT scores were significantly associated with advanced T stage and extrathyroidal extension. The CONUT score, which can be easily used in clinical practice, is thought to be helpful in predicting the aggressiveness of PTC.

Methods: In total, 176 stent-assisted coil embolization procedures were investigated. Among them, 77 ruptured and 99 unruptured aneurysms were grouped and compared respectively. In the ruptured group, only SAPT (aspirin) was administered after the procedure. Meanwhile, in the unruptured group, dual antiplatelet therapy (DAPT) (aspirin and clopidogrel) was administered before and after the procedure following standard guidelines. We compared both groups in regards to thromboembolic complications by analyzing post procedural diffusion-weighted images (DWI), hyperacute thrombosis during the procedure, and post-procedural symptoms. Results: The single antiplatelet therapy ruptured intracranial aneurysm (SAPT-RIA) group had 77 saccular aneurysms (62 ICA, 3 MCA, 4 ACA, 8 posterior circulation) with a mean diameter of 8.07 mm. The dual antiplatelet therapy unruptured intracranial aneurysm (DAPT-UIA) group had 99 aneurysms (81 ICA, 5 MCA, 3 ACA, 10 posterior circulation) with a mean diameter of 6.32 mm. DWI positivity rates were similar between groups, but hyperacute thrombosis was higher in the SAPT-RIA group (10.4%) compared to none in the DAPT-UIA group. Each group had one symptomatic complication. Conclusions SAPT could be a viable option for the peri-procedural management of SAC in acutely ruptured cases.
