    Background: Non-small cell lung cancer (NSCLC) is a leading cause of morbidity and mortality. Carboplatin and cisplatin based regimens are used in the treatment of NSCLC. The aim of the study was to find out whether there is a difference in white matter (WM) changes between two platinum-based chemotherapy agents using diffusion tensor imaging (DTI). Patients and methods: 25 patients who received chemotherapy for NSCLC and 27 age-matched healthy controls were enrolled in the study. Fractional anisotropy (FA), axial diffusivity (AD), mean diffusivity (MD) and radial diffusivity (RD) values of the study population were measured from 11 regions of interest in pre-chemotherapy and post-chemotherapy MRI data. Results: Cisplatin group showed a significant decrease in the FA of the inferior longitudinal fasciculus (P = 0.028). Carboplatin group showed a significant FA decrease and RD increase in the forceps minor (P = 0.022 and P = 0.011, respectively), and a significant reduction in AD and increase in MD in frontal white matter (WM) (P = 0.008 and P = 0.029, respectively). In comparison of post chemotherapy DTI values of the two groups, carboplatin group showed lower FA, and higher MD and RD values than cisplatin group in parieto-occipital WM (P = 0.034, P = 0.034, P = 0.029, respectively). Conclusions: The findings of the study suggest that subtle effects of chemotherapy detectable with DTI may emerge after the treatment. In addition, carboplatin regimen may have more impact on WM than cisplatin regimen.

    Anxiety levels of breast cancer patients in Turkey during the COVID-19 pandemic
    (2021-07-01T00:00:00Z) YASİN, Ayşe İrem; TOPÇU, Atakan; SHBAIR, ABDALLAH T.M.; SUCUOĞLU İŞLEYEN, ZEHRA; ÖZTÜRK, AHMET; BEŞİROĞLU, MEHMET; TÜRK, HACI MEHMET; YASİN, AYŞE İREM; TOPÇU, ATAKAN; SHBAIR, ABDALLAH T.M.; SUCUOĞLU İŞLEYEN, ZEHRA; ÖZTÜRK, AHMET; BEŞİROĞLU, MEHMET; TÜRK, HACI MEHMET
    Aim: To assess the anxiety levels of breast cancer patients during the COVID-19 pandemic. Materials & methods: A total of 298 patients completed the State-Trait Anxiety Inventory (STAI-S and STAI-T) and the Visual Analogue Scale for Anxiety (VAS) and VAS for Anxiety in COVID-19 (VAS-CoV). Results: 144 patients were in the high anxiety category for STAI-S, and 202 patients were in the high anxiety category for STAI-T. STAI-T score was significantly high in the metastatic group (p = 0.017). VAS-CoV score in the hormonotherapy group was significantly higher than in the no-treatment group (p = 0.023). There was a positive correlation between VAS-CoV and VAS levels (r = 0.708, p < 0.001), VAS-CoV and STAI-S and STAI-T scores (r = 0.402, p < 0.001; r = 0.185, p = 0.001, respectively), and a negative correlation between education years and STAI-T scores (r = -0.172, p = 0.003). Conclusion: The COVID-19 pandemic is related to high anxiety levels in breast cancer patients.

    Aim: To compare the seropositivity rate of cancer patients with noncancer controls after inactive SARS-CoV-2 vaccination and evaluate the factors affecting seropositivity. Method: Spike IgG antibodies against SARS-CoV-2 were measured in blood samples of 776 cancer patients and 715 noncancer volunteers. An IgG level ≥50 AU/ml is accepted as seropositive. Results: The seropositivity rate was 85.2% in the patient group and 97.5% in the control group. The seropositivity rate and antibody levels were significantly lower in the patient group (p < 0.001). Age and chemotherapy were associated with lower seropositivity in cancer patients (p < 0.001). Conclusion: This study highlighted the efficacy and safety of the inactivated vaccine in cancer patients.
