    Complete Remission of Burkitt Lymphoma After Surgical Excision: A Case Report
    (SPRINGER INDIA, 2016-01-01) Bekoz, Huseyin Saffet; Kantarcioglu, Bulent; Tecimer, Tulay; Uskent, Necdet; Cetiner, Mustafa; Ferhanoglu, Burhan; Sargin, Deniz
    Burkitt lymphoma (BL) is a highly aggressive B cell non-Hodgkin lymphoma that has a high proliferation rate. The prognosis for BL is generally favorable, with cure rate of 75-90 \% with modern chemoimmunotherapy regimens. Prompt administration of multiagent immunochemotherapy regimens is critical, because BL is almost always fatal if left untreated. Nevertheless here we report a case of BL that is still in complete remission after more than 4 years without any further treatment after surgical excision of the involved lymph node.

    Efficacy of Palbociclib and Endocrine Treatment in Heavily Pretreated Hormone Receptor-positive/HER2-negative Advanced Breast Cancer: Retrospective Multicenter Trial
    (GALENOS PUBL HOUSE, 2020-01-01) Demir, Atakan; Mandel, Nil Molinas; Paydas, Semra; Demir, Gokhan; Er, Ozlem; Turhal, Nazim Serdal; Bavbek, Sevil; Eralp, Yesim; Saip, Pinar Mualla; Guler, Emine Nilufer; Aydiner, Adnan; Uluc, Basak Oyan; Kilickap, Sadettin; Uskent, Necdet; Karadurmus, Nuri; Kaplan, Mehmet Ali; Yanmaz, Mustafa Teoman; Demir, Hacer; Alan, Ozkan; Korkmaz, Taner; Olgun, Polat; Uysal, Ozlem Sonmez; Altundag, Kadri; Gunduz, Seyda; Gunaldi, Meral; Sari, Murat; Beypinar, Ismail; Basaran, Gul
    Background: The synthesis of CDK4/6 inhibitors with endocrine treatment in two series of treatment has been widely accepted as the standard for patients with estrogen receptor-positive metastatic breast cancer. In spite of this, the activity of CDK4/6 inhibitors in patients with metastatic breast cancer who have progressed despite receiving multiple lines of treatment is not well understood. Aims: To report the activity and safety of a CDK4/6 inhibitor (palbociclib) in patients in whom at least three lines of treatment for ER+ metastatic breast cancer had failed. Study Design: Multicenter retrospective observational cohort study. Methods: In this retrospective observational cohort study, we included 43 patients who received palbociclib after at least three lines of systemic treatment for ER+/HER2- metastatic breast cancer. Results: The median progression-free survival in our population was 7 months (25th-75th percentile, 4-10), and the median overall survival was 11 months (25th-75th percentile, 6-19). Although there were some adverse events, palbociclib was generally well tolerated, so dose reduction was needed for only six patients (14\%). Conclusion: The efficacy of palbociclib among heavily treated hormone receptor-positive/HER2- patients with advanced breast cancer was acceptable in terms of clinical benefit, and it was generally well tolerated among this population.

    Prognostic Significance of Tumor Tissue NeuGcGM3 Ganglioside Expression in Patients Receiving Racotumomab Immunotherapy
    (HINDAWI LTD, 2020-01-01) Uskent, Necdet; Ayla, Sule; Mandel, Nil Molinas; Ozkan, Metin; Teomete, Mehmet; Baloglu, Huseyin; Aydincer, Cenk; Yergok, Hale; Dogan, Ender; Berk, Barkin; Yazar, Aziz
    Expression ofN-glycolyl GM3 (NeuGcGM3) ganglioside was detected in the tumor specimens of patients who were on Racotumomab anti-idiotype vaccine maintenance treatment, and prognostic significance as a biomarker was investigated. No statistically significant association was observed in the multivariate analysis between overall survival and tissue NeuGcGM3 IHC levels. Although numerically there was a difference favoring less intense IHC for better prognosis, this did not reach statistical power. However, there was a strong correlation between Racotumomab doses and overall survival (OS). Mean OS of the patient with more than 10 Racotumomab application was significantly longer than the patient who had less than 10 injections (70.7 months vs. 31.1 months, p<0.001). We propose that, regardless of staining intensity, the presence of NeuGcGM3 in patient tissues might be an indicator of benefit in Racotumomab treatment.
