Objectives: Advanced gastric cancer (AGC) patients have a poor prognosis. The best benefit of chemotherapy is usually achieved by first line setting. Very few studies have compared combination regimens. This study was designed to compare two combination regimens. Methods: Patients with advanced gastric cancer receiving first line chemotherapy were retrospectively collected, and divided into two groups, receiving DCF (docetaxel, cisplatin and fluorouracil) or ECF (epirubicin, cisplatin and fluorouracil) regimens. Data were collected for the retrospective analysis in a single center. Results: Eighty-six patients were eligible for analysis. Median overall survival (OS) was 10.0 months in the ECF group and 11.0 months in the DCF group (p=0.31). Median progression free survival (PFS) for ECF and DCF was equal at 6.0 months. Second line chemotherapy were administered in more than one third of patients. Both regimens had similar toxicity. Conclusions: This is the first study investigating the outcomes of gastric cancer chemotherapy in this region. ECF and DCF regimens have similar efficacy and a similar tolerability profile for first line treatment of advanced gastric cancer. The decision of the first line chemotherapy in advanced gastric cancer could be improved with patient selection according to clinical parameters and molecular markers.

Background: Lung cancer (LC) is still the primary cause of cancer deaths worldwide, and late diagnosis is a major obstacle to improving lung cancer outcomes. Recently, elevated preoperative or pretreatment neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and mean platelet volume (MPV) detected in peripheral blood were identified as independent prognostic factors associated with poor survival with various cancers, including colon cancer, esophageal cancer, gastric cancer and breast cancer. Objective: The aim of this study was to examine whether MPV, NLR and PLR could be useful inflammatory markers to differentiate lung cancer patients from healthy controls. An investigation was also made of the relationship between these markers and other prognostic factors and histopathological subgroups. Materials and Methods: Retrospectively eighty-one lung cancer patients and 81 age-sexes matched healthy subjects included into the study. Patients with hypertension, hematological and renal disease, heart failure, chronic infection, hepatic disorder and other cancer were excluded from the study. The preoperative or pretreatment blood count data was obtained from the recorded computerized database. Results: NLR and PLR values were significantly higher in the LC patients compared to the healthy subjects.( NLR: 4.42 vs 2.45 p=0.001, PLR: 245.1 vs 148.2 p=0.002) MPV values were similar in both groups (7.7 vs 7.8). No statistically significant relationship was determined between these markers (MPV, NLR and PLR) and histopathological subgroups and TNM stages. Conclusions: NLR and PLR can be useful biomarkers in LC patients before treatment. Larger prospective studies are required to confirm these findings.
