Survival Benefits of Laparoscopic Gastrectomy in Elderly Patients With Gastric Cancer: Focusing on Preoperative Nutritional and Inflammatory Status.

BACKGROUND/AIM: Laparoscopic gastrectomy (LG) may have greater clinical benefits as a less invasive surgery for elderly patients with gastric cancer (GC). Therefore, we aimed to evaluate the survival benefit of LG in elderly patients with GC, especially focusing on preoperative comorbidities, and nutritional and inflammatory status. PATIENTS AND METHODS: Data collected from 115 patients aged ≥75 years with primary GC who underwent curative gastrectomy, comprising 58 patients who underwent open gastrectomy (OG) and 57 patients who underwent LG, were retrospectively reviewed (total cohort), and 72 propensity-matched patients (matched cohort) were selected for survival analysis. The aim of the study was to determine short- and long-term outcomes, and the clinical markers to identify a population who may benefit from LG in elderly patients. RESULTS: The complication and mortality rates as a short-term outcome in the total cohort and overall survival (OS) as a long-term outcome in the matched cohort did not differ significantly between the groups. In the total cohort, advanced tumor stage and ≥3 comorbidities were independent factors for poor prognosis in terms of OS [hazard ratio (HR)=3.73, 95% confidence interval (CI)=1.78-7.78, p<0.001 and HR=2.50, 95% CI=1.35-4.61, p<0.01, respectively]. The surgical approach was not an independent risk factor for postoperative complications (grade ≥III) and OS. In subgroup analysis of the total cohort, patients with a neutrophil-lymphocyte ratio (NLR) ≥3 in the LG group demonstrated a trend toward greater OS (HR=0.26, 95% CI=0.10-0.64, interaction p<0.05). CONCLUSION: LG might offer greater survival benefits than OG in frail patients such as those with high NLR.

Solitary fibrous tumor of the lung: a case report.

Solitary fibrous tumors (SFTs) are relatively rare neoplasms that commonly occur in the pleura. The pathological feature of SFTs is a proliferation of spindle-shaped cells in interlacing or storiform fascicles. SFTs appear to derived from pluripotential submesothelial cells, but not the covering mesothelium. SFTs distinctively show diffuse staining for CD34 but lack staining for smooth muscle markers. We herein report a relatively rare case of a 68-year-old male patient without symptoms, who underwent resection for what was considered to be SFT.
