Does preoperative positron emission tomography help delineate the boost volume after oncoplastic surgery for breast cancer?
Yıldırım Altınok, Ayşe; Doyuran, Mine; Çağlar, Mustafa; Çakır, Tansel; Acar, Hilal; Küçükmorkoç, Esra; Küçük, Nadir; Çağlar, Hale; Atasever, Tamer (Kare Publishing, 2017)OBJECTIVE The tumor bed within the breast shifts during oncoplastic surgery (OPS) for breast cancer (BC). Preoperative imagery is used to determine the boost volume (BV) for patients not implanted with surgical clips. This ... -
Dosimetric comparison of helical tomotherapy, intensity-modulated radiation therapy, volumetric-modulated arc therapy, and 3-dimensional conformal therapy for the treatment of T1N0 glottic cancer
Ekici, Kemal; Kaya Pepele, Eda; Yaprak, Bahaddin; Temelli, Öztun; Eraslan, Aysun Fatma; Küçük, Nadir; Yıldırım Altınok, Ayşe; Altınok Süt, Pelin; Alpak, Özlem D.; Çolak, Cemil; Mayadağlı, Alpaslan (Elsevier Science Inc, 2016)Various radiotherapy planning methods for T1N0 laryngeal cancer have been proposed to decrease normal tissue toxicity. We compare helical tomotherapy (HT), linac-based intensity-modulated radiation therapy (IMRT), ... -
Dosimetric evaluation of right coronary artery in radiotherapy for breast cancer
Yıldırım Altınok, Ayşe; Askeroğlu, Orbay; Doyuran, Mine; Çağlar, Mustafa; Cantürk, Emir; Erol, Cengiz; Şenel Beşe, Nuran (Elsevier Inc., 2019)Comparison with control groups of untreated patients suggests that right-breast-cancer patients who receive radiotherapy have a higher rate of heart disease. Dose constraint for heart has been established to minimize ... -
Dosimetric evaluation of the dose calculation accuracy of different algorithms for two different treatment techniques during whole breast irradiation
Acar, Hilal; Yıldırım Altınok, Ayşe; Cebe, Mehmet Sıddık (Springer, 2019)Objective In-field, partially in-field, and out-of-field organ doses calculated by the Acuros XB (AXB) and analytical anisotropic algorithm (AAA) were compared with experimentally measured data for two different techniques ... -
