MRI and CT imaging for preoperative target volume delineation in breast-conserving therapy
BACKGROUND Accurate tumor bed delineation after breast-conserving surgery is important. However, consistency among observers on standard postoperative radiotherapy planning CT is low and volumes can be large due to seroma formation. A preoperative delineation of the tumor might be more consistent. Therefore, the purpose of this study was to determine the consistency of preoperative target volum...
متن کاملTarget volume delineation in breast conserving radiotherapy: are co-registered CT and MR images of added value?
INTRODUCTION In breast conserving radiotherapy differences of target volume delineations between observers do occur. We evaluated whether delineations based on co-registered computed tomography (CT) and magnetic resonance (MR) imaging may result in an improved consistency between observers. We used the delineation conformity index (CI) to compare clinical target volumes of glandular breast tiss...
متن کاملDifferent methods for target volume delineation of glandular breast tissue following breast-conserving surgery in breast cancer: A comparative study.
The present study aimed to investigate an optimal and feasible method for delineating the target volume of glandular breast tissue following breast-conserving surgery. A total of 15 patients who underwent radiotherapy following breast-conserving surgery were recruited into the study. Clinical target volume was delineated by the following three methods based on computed tomography (CT): Anatomic...
متن کاملFDG-PET/CT imaging for staging and target volume delineation in conformal radiotherapy of anal carcinoma
BACKGROUND FDG-PET/CT imaging has an emerging role in staging and treatment planning of various tumor locations and a number of literature studies show that also the carcinoma of the anal canal may benefit from this diagnostic approach. We analyzed the potential impact of FDG-PET/CT in stage definition and target volume delineation of patients affected by carcinoma of the anal canal and candida...
متن کاملVolume of breast tissue excised during breast-conserving surgery in patients undergoing preoperative systemic therapy.
PURPOSE We aimed to determine whether clinical examination could adequately ascertain the volume of tissue to be resected during breast-conserving surgery after neoadjuvant therapy. METHODS We reviewed the clinical reports of 279 patients with histologically diagnosed invasive breast carcinomas treated with neoadjuvant therapy followed by surgery or with primary surgery alone. We estimated vo...
