Challenges in defining radiation pneumonitis in patients with lung cancer
Zafer Kocak,Zafer Kocak,Elizabeth S. Evans,Su Min Zhou,Keith L. Miller,Rodney J. Folz,Timothy D. Shafman,Lawrence B. Marks +7 more
TL;DR: Scoring of radiation pneumonitis was challenging in 28% of patients treated for lung cancer owing to confounding medical conditions, and recognition of this uncertainty is needed and may limit the ability to understand RT-induced lung injury.
Journal ArticleDOI
High Plasma d-dimer Level is Associated with Decreased Survival in Patients with Lung Cancer
Gündeniz Altiay,A. Ciftci,Muzaffer Demir,Zafer Kocak,Necdet Sut,Erhan Tabakoğlu,Osman Nuri Hatipoğlu,Tuncay Çağlar +7 more
TL;DR: Elevated plasma levels of D-dimer in patients with lung cancer are associated with decreased survival and a poor response to treatment, and pre-treatment for the D-Dimer level may be useful in the prediction of survival and the response totreatment.
Journal ArticleDOI
Extrapulmonary small-cell carcinoma compared with small-cell lung carcinoma: a retrospective single-center study.
Irfan Cicin,Hakan Karagol,Sernaz Uzunoglu,Kazim Uygun,Ufuk Usta,Zafer Kocak,Murat Caloglu,Mert Saynak,Fusun Tokatli,Cem Uzal +9 more
TL;DR: The study was conducted with the aim of reviewing the clinical features, therapy, and natural course of patients with extrapulmonary small‐cell carcinoma (EPSCC) and SCLC to better define current concepts regarding EPSCCs.
Journal ArticleDOI
Prospective assessment of dosimetric/physiologic-based models for predicting radiation pneumonitis.
Zafer Kocak,Zafer Kocak,Gerben R. Borst,Jing Zeng,Sumin Zhou,Donna Hollis,Junan Zhang,Elizabeth S. Evans,Rodney J. Folz,Terrence Wong,D. Kahn,José Belderbos,Joos V. Lebesque,Lawrence B. Marks +13 more
TL;DR: The prospective model appears unable to accurately segregate patients into high vs. low risk groups of RT-induced lung injury, which is consistent with prior studies suggesting that dosimetric and functional parameters are predictive for RT- induced pneumonitis.
Journal ArticleDOI
Granulosa cell tumor of the ovary: retrospective analysis of 45 cases.
Kazim Uygun,Adnan Aydiner,Pinar Saip,Mert Basaran,Faruk Tas,Zafer Kocak,Maktav Dincer,Erkan Topuz +7 more
TL;DR: Despite the small number of patients, the study showed that stage and macroscopic residual disease are significant prognostic factors and the benefit of chemotherapy and radiotherapy remains controversial.
