BACKGROUND AND OBJECTIVES The objectives of this study were to test the feasibility of sole interstitial high-dose-rate brachytherapy (HDR-BT) after breast-conserving surgery (BCS) for T1 breast cancer in a phase I-II study, and to present the initial findings of a phase III trial comparing the efficacy of tumor bed radiotherapy (TBRT) alone with(More)
PURPOSE To report the 5-year results of a randomized study comparing the survival and cosmetic results of breast-conserving treatment with partial breast irradiation (PBI) or conventional whole breast irradiation (WBI). METHODS AND MATERIALS Between 1998 and 2004, 258 selected patients with T1 N0-1mi, Grade 1-2, nonlobular breast cancer without presence(More)
PURPOSE To report the 7-year results of a prospective study of accelerated partial breast irradiation (APBI) using interstitial high-dose-rate brachytherapy and compare the treatment results with those achieved by standard, whole breast radiotherapy (WBRT), with or without a tumor bed boost (TBB). METHODS AND MATERIALS Between 1996 and 1998, 45(More)
To evaluate the effect of electron and high-dose-rate brachytherapy (HDR BT) boost on local tumor control (LTC), side effects and cosmesis after breast-conserving surgery (BCS) in a prospective randomized study. Patients and Methods: 207 women with stage I–II breast cancer who underwent BCS were treated by 50 Gy irradiation to the whole breast and then(More)
The standard technique of radiotherapy (RT) after breast conserving surgery (BCS) is to treat the entire breast up to a total dose of 45–50 Gy with or without tumor bed boost. The majority of local recurrences occur in close proximity to the tumor bed. Thus, the necessity of whole breast radiotherapy has been questioned, and several centers have evaluated(More)
Recently, the use of brachytherapy for partial breast irradiation has increased significantly. The aim of this study was to make dosimetric comparisons between conventional (CONV) and CT-based optimized dosimetry systems applied to breast implants. 17 patients treated with high-dose-rate (HDR) interstitial brachytherapy were selected for the study. Two(More)
The aim of the study was to test the hypothesis, if there were subgroups of early breast cancer patients in which sole brachytherapy (BT) of the tumor bed was a feasible and safe treatment option after breast conserving surgery (BCS). Forty four prospectively selected patients with Stage I-II breast cancer were entered into a protocol of postoperative tumor(More)
In this report, a unique case of a localized (T1N0M0) adenocarcinoma of the head of the pancreas is presented, which was successfully treated with interstitial high dose rate brachytherapy combined with percutan irradiation after biopsy. A total dose of 18 Gy was delivered with brachytherapy (6 Gy per fraction on three consecutive days) to the tumor via(More)
To compare the conventional 2-D, the simulator-guided semi-3-D and the recently developed CT-guided 3-D brachytherapy treatment planning in the interstitial radiotherapy of breast cancer. Patients and Methods: In 103 patients with T1-2, N0-1 breast cancer the tumor bed was clipped during breast conserving surgery. Fifty-two of them received boost(More)
In recent years, there has been a dramatic increase in the number of tumors of the head and neck. Their successful treatment is one of the greatest challenges for physicians dealing with oncotherapy. An organic part of the complex therapy is preoperative or post-operative irradiation. Application of this is accompanied by a lower risk of recurrences, and by(More)
