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.

Abstract Background: Red cell distribution width (RDW) is a routinely examined parameter with the complete blood count. In recent studies, RDW levels have been associated with cardiovascular, liver and renal diseases and solid tumors. The aim of this study was to evaluate the alterations of RDW levels in benign and malignant causes of postmenopausal bleeding and to investigate the association of RDW levels with clinicopathological parameters of endometrial cancer (EC) patients. Methods: A retrospective study was made of a total of 884 females who were admitted to hospital for postmenopausal bleeding between May 2009 and December 2013. After inclusion and exclusion criteria were applied, 222 patients remained. Complete blood count data was obtained from the recorded computerized database. After pathological evaluation, the patients were divided into two groups, benign and malignant (EC). Results: The EC group (n=113) had significantly higher RDW levels compared to the benign group (14.78±2.02 vs. 13.88±1.05; p=0.000). Grade II and above EC patients had higher levels of RDW than Grade I patients (15.2±2.3 vs. 14.1±1.00; p=0.005). Correlation analyses also revealed a negative correlation between RDW and hemoglobin levels (p=0.000), RDW and mean corpuscular volume (p=0.000), RDW and lymphocyte count (p=0.035) but a positive correlation between RDW and platelet to lymphocyte ratio (p=0.030). Conclusions: The results of the current study revealed the potential predicitve role of RDW in patients with postmenopausal bleeding. Significant associations were also determined between RDW and clinicopathological characteristics in EC patients.

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.

Skin metastasis originating from colorectal cancer is a rare entity and usually signifies poor prognosis. We present a case of a 62-year-old male patient who presented with a cutaneous metastatic focus on his forehead after five years of the primary treatment of colon cancer. Complete response from the cutaneous metastasis nodule was achieved with radiotherapy. The patient is still alive and under a second-line palliative chemotherapy regimen because of the multiple liver metastases. It is important for physicians to be aware of skin metastasis in patients with an oncology history.

Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumour in adults. Identification of accessible and cost-effective prognostic factors may better guide adjuvant treatment-related decisions. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are markers of host inflammatory response, and their increase has recently been shown to be a poor prognostic factor in several malignancies. The aim of the present study was to investigate the prognostic value of preoperative NLR and PLR in GBM patients. Between 2012 and 2017, 104 patients who had undergone surgery for GBM were considered for adjuvant therapy in our institution. Of those, 80 patients with evaluable pre-corticosteroid full blood count results were identified and included in the final analysis. The Eastern Cooperative Oncology Group performance status, localization, radiochemotherapy and second-line systemic therapy were found to be independent prognostic indicators for progression-free and overall survival. The median overall survival was 13.2 months. Patients with NLR <4 had a better median overall survival of 10.7 vs. 7.8 months in patients with NLR >4; however, this difference was not statistically significant (P>0.05). Overall survival also did not differ significantly between patients with low and those with high PLR values (10.2 vs. 15.2 months, respectively; P=0.105). In conclusion, the results of the present study suggest that pre-treatment NLR and PLR do not have prognostic value in GBM patients; however, large-scale trials are required to confirm these findings.

Advanced gastric cancer has a poor prognosis, and only chemotherapy improves survival. Further chemotherapy after progression is controversial. Eastern Cooperative Oncology Group performance status is an important indicator for new chemotherapy decision. Complete response (CR) after recurrent disease is very rare, but could occur in some cases with chemotherapy. The 68-year-old male received chemotherapy for metastatic gastric adenocarcinoma. He received epirubicin, cisplatin and fluorouracil in the first line, capecitabine in the second line and cisplatin-capecitabine in the third line. CR was observed after third-line chemotherapy with four courses. Mediastinal and abdominal metastases were completely resolved. We decided to report this patient because it is very unusual to achieve CR in a patient in whom the best supportive care might be reasonable.

Solid tumorlerin meme metastazina cok sik olmasa da klinik pratik hayatimizda rastlamaktayiz ancak servikal kanserin memeye yayilimi literaturde de cok nadir bildirilmektedir. Olgumuz 65 yasinda, evre IV yassi hucreli serviks kanseri nedeni ile 3 kur birinci seri kemoterapi aldiktan sonra meme metastazi gelisti. Primer meme kanseri dusunulerek alinan biyopsinin patolojik incelenmesinde az diferansiye yassi hucreli kanser metastazi oldugu goruldu. Bu olgu kanser oyusu olan hastalarda dogru tedavi karari verebilmek icin ayirici taninin onemini bir kez daha vurgulamaktadir.
