    (Future Medicine Ltd., 2016) Yazici O.; Özdemir N.; Duran A.O.; Menekşe S.; Nahit Şendur M.A.; Karaca H.; Göksel G.; Arpaci E.; Hacibekiroʇlu I.; Bilgetekin I.; Kaçan T.; Özkan M.; Aksoy S.; Aksoy A.; Çokmert S.; Uysal M.; Elkiran E.T.; Çiçin I.; Büyükberber S.; Zengin N.
    Aim: To investigate the role of surgical resection of primary tumor on overall survival (OS) in advanced gastric cancer patients at the time of diagnosis. Patients & methods: The survival rates of metastatic gastric cancer patients whose gastric primary tumor was resected at time of diagnosis were compared with metastatic gastric cancer patients whose primary tumor was nonresected. Results: The median progression-free survival and OS in operated and nonoperated group were 10 versus 6, 14 versus 9 months, respectively (p < 0.001). In multivariate analysis, gastric resection of primary tumor, Eastern Cooperative Oncology Group performance status, second-line chemotherapy had a significant effect on OS (hazard ratio [HR]: 0.52 [95% CI: 0.38-0.71], HR: 0.57 [95% CI: 0.42-0.78], HR: 1.48 [1.09-2.01]; p ≤ 0.001, p = 0.001 and p = 0.012, respectively). Conclusion: Subpopulations of patients with metastatic gastric cancer might benefit from surgical removal of primary tumor. © 2016 Future Medicine Ltd.

    Trastuzumab in combination with AT-101 induces cytotoxicity and apoptosis in Her2 positive breast cancer cells
    (Future Medicine Ltd., 2019) Bulut G.; Atmaca H.; Karaca B.
    Aim: AT-101 is a polyphenolic compound with potent anti-apoptotic effects in various cancers. In this study, the possible synergistic cytotoxic and apoptotic effect of trastuzumab/AT-101 combination was investigated in HER2-positive breast cancer cell lines. Materials & methods: SKBR-3, MDA-MB-453 and MCF-10A cell lines were treated with a trastuzumab/AT-101 combination. Synergistic cytotoxicity and apoptosis effects were shown and then PI3K and Akt protein levels were studied. Result: The trastuzumab/AT-101 combination induced synergistic cytotoxicity and apoptosis in both breast cancer cells but not in MCF-10A cells. Combination treatment induced cytotoxicity via inhibiting PI3K/AKT but not the MAPK/ERK pathway. Conclusion: The trastuzumab/AT-101 combination may be a good candidate for patients with trastuzumab-resistant Her2-positive breast cancer and inhibition of the PI3K/AKT pathway may be one of the underlying mechanisms. © 2019 Gulcan Bulut, Harika Atmaca & Burcak Karaca.

    Relationship between IL-6 and COVID-19: To be considered during treatment
    (Future Medicine Ltd., 2020) Vatansever H.S.; Becer E.
    The detection and control of pro-inflammatory response is crucial in the early stages of viral infection. Coronavirus disease 2019 (COVID-19) is an emerging viral disease of global concern and optimal treatment has yet to be determined. Unknown response of treatment of COVID-19 is important during patient monitoring. IL-6 is one of the key cytokines after activated macrophages. Therefore, control of systemic IL-6 levels in SARS-CoV-2 infected patients may be a parameter for COVID-19 disease. This review is focused on the induction of IL-6 after viral infections as a target molecule for monitoring cellular response. © 2021 Future Medicine Ltd.
