Journal ArticleDOI
Single versus multichannel applicator in high-dose-rate vaginal brachytherapy optimized by inverse treatment planning.
Yasir A. Bahadur,C. Constantinescu,Ashraf H. Hassouna,Maha M. Eltaher,Noor M. Ghassal,Nesreen A. Awad +5 more
TL;DR: Vaginal HDR brachytherapy using a multichannel vaginal applicator and inverse planning provides dosimetric advantages over single channel cylinder, by reducing the dose to organs at risk without compromising the target volume coverage, but at the expense of an increased vaginal mucosa dose.
Journal ArticleDOI
Uterine perforation and its dosimetric implications in cervical cancer high-dose-rate brachytherapy
TL;DR: A low incidence of uterine perforation and sub-serosal insertion of intra-uterine tandem in intracavitary HDR brachytherapy for cervical cancer is reported, however, the effects on treatment plan dosimetry can be considerably detrimental.
Journal ArticleDOI
Assessment of air pockets in high-dose-rate vaginal cuff brachytherapy using cylindrical applicators.
TL;DR: The presence of air pockets around vaginal cylinder applicators is frequently noticed in post-operative vaginal cuff brachytherapy, and the dose to the vaginal mucosa is reduced, as a result of displacement generated by air pockets.
Journal ArticleDOI
Prognostic value of lymph node ratio in poor prognosis node-positive breast cancer patients in Saudi Arabia.
Ezzeldin M. Ibrahim,Tawfik R El-Khodary,Jamal Zekri,Yasir A. Bahadur,Mohamed E El-Sayed,Aboelkhair M Al-Gahmi,Syed Azhar J Rizvi,Ashraf H. Hassouna,Ehab E. Fawzy,Said S Awadalla +9 more
TL;DR: Women in Saudi Arabia develop breast cancer at a young age with high prevalence of poor prognostic features, and one such factor is the prognostic role of lymph node ratio (LNR).
Journal Article
Treatment planning for high dose rate brachytherapy of cervical cancer based on total dose constraints.
TL;DR: Significant differences between point doses and dose volume histogram parameters indicate the need for inverse planning in image-guided brachytherapy of cervical cancer.
