Biography

My name is Ghizela Ana Maria Salagean, I am a medical physicist in my 4^th year of activity, currently enrolled in my second year of PhD studies at University of Babes Bolyai Cluj-Napoca.During my university studies and later due to my professional activities I have developed an interest in research, that is why I have decided to pursue a PhD focused on bolus material. Over the years, I have become a communicative, dynamic, and sociable person. I can say that I am an ambitious person, when I set my mind to something, I do not give up until I achieve it. My interest in radiotherapy mostly is focused on breast cancer and bolus materials, but I like the dosimetry part also. 

Abstract

Synchronous bilateral breast cancer (SBBC) represents a challenge among breast cancer patients, most cases requiring adjuvant radiotherapy. The purpose of this study was to evaluate the optimal radiotherapy (RT) plan technique for a case of SBBC, after breast-conserving surgery.

Materials/Methods: We present the case of an SBBC cancer patient, who underwent bilateral sectorectomy with sentinel node biopsy with pathology revealing: pT2N0sn (right side), pT1N0sn (left side). Adjuvant treatment consisted of chemotherapy and bilateral adjuvant radiotherapy to a dose of 40.05Gy in 15 fractions. Four different bilateral breast cancer treatment techniques were evaluated, using a single isocentre for the dynamic multi-leaf collimator intensity-modulated radiation therapy (dMLC-IMRT), tangential volumetric modulated arc therapy (t-VMAT) and volumetric modulated arc therapy (VMAT) plans, and a double isocentre technique for three-dimensional conformal radiation therapy (3D-CRT) plan, respectively.

Conclusion: SBBC irradiation using a hypo fractionated schedule with single isocentre dMLC-IMRT plan is technically feasible, practical, and safe regarding OARs. We identified the IMRT approach as the optimal one in our arsenal. We wish to further analyze e.g.gated techniquesandtreatmentdeliverytimes.
