Prognostic impact of immune inflammation biomarkers in predicting survival and radiosensitivity in patients with non-small-cell lung cancer treated with chemoradiotherapy.

INTRODUCTION: The purpose of this retrospective study was to investigate the prognostic impact of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), derived NLR (dNLR) and systemic immune-inflammation index (SII) in predicting outcomes for patients with locally advanced non-small-cell lung cancer (NSCLC). The secondary endpoint was to evaluate the radiosensitivity in terms of response rate. METHODS: Newly diagnosed locally advanced NSCLC patients were enrolled. Immune inflammation biomarkers were calculated from baseline blood samples. Patients were stratified in two groups based on optimal cut-off values for each biomarker. The associations between biomarkers and overall survival (OS), progression-free survival (PFS), local regional recurrence-free survival (LRRFS), and also response to radiotherapy were analysed. RESULTS: A total of 392 patients were included. Five-year OS, PFS and LRRFS rates were 14.6%, 12.1%, and 13.4% respectively. Optimal cut-off values for NLR, PLR, dNLR and SII were 3.07, 166, 2.02 and 817 respectively. Low NLR (HR 1.73, 95% CI 1.34-2.24, P < 0.001), low PLR (HR 1.37, 95% CI 1.06-1.76, P = 0.013), low dNLR (HR 1.66, 95% CI 1.29-2.13, P < 0.001) and low SII (HR 1.63, 95% CI 1.18-2.04, P < 0.001) were independent prognostic factors for OS. Low NLR, PLR, dNLR and SII were also significant prognostic factors for PFS and LRRFS. Low NLR, low dNLR and low SII groups had better radiosensitivity than compared with high NLR, high dNLR and high SII groups (P = 0.001, P = 0.001 and P = 0.012). CONCLUSION: NLR, PLR, dNLR and SII were independently associated with improved OS, PFS and LRRFS. Low NLR, dNLR and SII groups had better radiosensitivity. Immune inflammation biomarkers are promising prognostic predictors which can be obtained easily and inexpensively.

Evaluation of the Efficacy of the Three-Component Health Care Management Program HEWCOT in Colorectal Cancer Patients Receiving Chemotherapy.

This study was performed to evaluate effects of education, home visits, web, and phone counseling on chemotherapy symptoms and anxiety in patients with colorectal cancer receiving chemotherapy. This pretest-posttest, quasi-experimental study was conducted in a chemotherapy unit of a hospital between February 2014 and October 2015. Due to dropouts from the study, was completed on 51 participants in the control group and 31 participants in the experimental group. The experimental group was offered a program that includes home visit, nursing education, web counseling, and tele-counseling (HEWCOT), developed by the researchers, to control symptoms and to reduce anxiety. The experimental group less frequently experienced constipation, pain, pricking and numbness in hands and feet, skin and nail problems, ocular problems, weakness, headache, mouth and throat problems, anxiety, and restlessness than the control group. The experimental group had less severe infection symptoms, hair loss, and mouth and throat problems after the interventions than the control group. In this study, the patients followed at home and provided web counseling and tele-counseling experienced less frequently chemotherapy symptoms.

Radiotherapy with or without temozolomide in elderly patients aged ≥ 70 years with glioblastoma.

INTRODUCTION: Although the recommended optimal treatment of glioblastoma multiforme (GBM) is adjuvant chemoradiotherapy, trials in GBM have excluded patients older than 70 years. In this study, we aimed to assess overall survival (OS) and prognostic factors in elderly patients (≥ 70 years) with newly diagnosed GBM treated with radiotherapy (RT) ± concurrent/adjuvant temozolomide (TMZ). MATERIAL AND METHODS: Inclusion criteria were patients ≥ 70 years, pre-RT Karnofsky performance status (KPS) ≥ 60, and time between diagnosis and start of RT ≤ 2 months. A total of 40 patients aged ≥ 70 years, 12 female and 28 male, treated between January 2004 and December 2012, were evaluated. Median age was 73.5 years (range, 70-83 years). The median RT dose was 60 Gy (range, 30-62 Gy). Twenty-one (52.5%) received concurrent TMZ, and of those 12 (30%) went on to receive adjuvant TMZ. RESULTS: The median OS was 7 months (95% CI: 5.45-8.54). One- and two-year OS for the whole cohort was 38% and 16%, respectively. Sex, type of surgery, tumor size, and RT dose did not significantly affect the OS. Presence of concurrent TMZ (p < 0.005) and presence of adjuvant TMZ (p < 0.001) were associated with longer OS in our cohort. CONCLUSIONS: RT ± TMZ seems to be a well-tolerated treatment in patients ≥ 70 years with GBM. Even though no superiority was found between conventional or hypofractionated RT regimens (p = 0.405), the addition of concurrent and adjuvant TMZ to RT increased the OS in our study.

HLA alleles and lung cancer in a Turkish population.

BACKGROUND: The concept of genetic factors playing a role in the pathogenesis of lung cancer has gained increased attention. The present study was undertaken to examine the question of HLA association with lung cancer and to investigate the effects of HLA on survival time. METHODS: The distribution of HLA class I (A, B, C) antigens and class II (DR, DQ) alleles were studied in 81 unrelated Turkish patients with lung cancer. The HLA status of patients was compared with that of a control group consisting of 117 ethnically matched healthy donors. HLA class I antigens were studied by Terasaki's microlymphocytotoxicity test and HLA class II alleles were studied by polymerase chain reaction with the sequence specific primer (PCR-SSP) low resolution method. RESULTS: Only the frequencies of HLA-B51 and -DRB1x15 were lower in the lung cancer group compared with the healthy control patients. In a univariate analysis, age (P=0.03), Karnofsky Performance Status (P=0.0001), stage (P=0.01), HLAA24(9) (P=0.008), HLA B53 (P=0.0006), HLA B63(15) (P=0.01), HLA B64(14) (P=0.01), HLA B65(14) (P=0.01) and HLA CW5 (P=0.01) were significant prognostic factors. In a multivariate analysis, Karnofsky Performance Status (P=0.001), stage (P=0.02), HLA B53 (P=0.03) and HLA B64(14) (P=0.03) were independent prognostic variables. CONCLUSIONS: This study demonstrates different HLA types among patients with lung cancer and healthy control subjects. Our results suggest that HLA antigens might affect the prognosis in lung cancer. Further investigations are warranted to delineate any possible role of the HLA system in the pathogenesis and prognosis of lung cancer.
