The aim of the present study was to determine the most meaningful preoperative prognostic factor of cancer-related death in ovarian cancer patients by comparing potentially prognostic systemic inflammatory response (SIR) markers. The levels of fibrinogen, albumin, C-reactive protein (CRP), and serum cancer antigen-125 (CA-125) and the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) were evaluated in 190 ovarian cancer patients to identify predictors of overall survival (OS) and progression-free survival (PFS) using univariate and multivariate analyses. Patients with a PLR >203 had a shorter PFS and OS than the patients in PLR ≤203 group (11 vs. 24 months and 28 vs. 64 months). Univariate analyses revealed that tumor stage, postoperative residual tumor mass, ascites, and the levels of all SIR markers were associated with PFS and OS. Multivariate analysis revealed that PLR was independently associated with PFS (hazard ratio [HR] 1.852, 95% confidence interval [CI] 1.271-2.697, P = 0.001) and OS (HR 2.158, 95%CI 1.468-3.171, P< 0.001), as well as tumor stage and postoperative residual tumor mass. In contrast, fibrinogen remained significant only for PFS (HR 1.724, 95%CI 1.197-2.482, P = 0.003). Patients with a PLR >203 were more prone to have advanced tumor stage (P = 0.002), postoperative residual tumor mass >2 cm (P = 0.032), malignant ascites (P < 0.001), and all the other elevated SIR markers (P < 0.001). Preoperative PLR is superior to other SIR markers (CA-125, NLR, fibrinogen, CRP, and albumin) as a predictor of survival in ovarian cancer patients.

Gastric metastases from lung adenocarcinoma are rare and usually asymptomatic. A 61-year-old woman was referred to our department because of a right lower pulmonary mass found on a chest X-ray film in August 2012. Right lower lobectomy was performed for pulmonary adenocarcinoma. Four months later, she developed epigastric discomfort. A fluoro-deoxy-glucose positron emission tomography/computed tomography (FDG-PET/CT) scan showed a malignancy at the cardias of the stomach. A biopsy diagnosed poorly differentiated carcinoma and a gastric carcinoma was suspected. She underwent a subtotal gastrectomy and part of esophagectomy. The histologic diagnosis was metastasis from the pulmonary adenocarcinoma. She visited us again for her increasing level of carcinoembryonic antigen (CEA) after two months. FDG-PET/CT showed multiple malignant lesions in her liver, considering metastases from pulmonary origin. As she harbored activating epidermal growth factor receptor (EGFR) mutation, she received erlotinib from April, 2013. She survives 4 years after the lung resection and is still on erotinib treatment with complete response. Although gastric metastasis from lung cancer is considered a late stage of the disease, a radical resection might provide survival in solitary metastasis. Moreover, systemic therapy was emphasized after local treatment in some late stage cases.
