The two therapeutic modalities were compared in terms of the following parameters; i.e. cosmesis, optimization of tumor bed boost, local control, toxicity, and DFS. Saudi Med J. 2012 Apr;33(4):353-66. Tumor bed boost radiotherapy in breast cancer. A review of current techniques. Bahadur YA(1), Constantinescu CT. We demonstrate the feasibility of a tumor bed localization and treatment procedure that seems adaptable to routine practice. The use of more than 1 clip associated with pre- to postoperative CT image registration allows better definition of the PTV boost volume.
The increase dose to the tumor bed after breast irradiation increases the rate of local control. Different techniques are used to deliver the boost to the tumor bed: the direct beam of electrons, photons with reduced tangential fields, low (LDR) and high dose rate (HDR) brachytherapy. Retrospective dose-response data suggest that a boost of about 15 Gy to the tumor bed following whole-breast radiotherapy reduces the risk of local recurrence (IBTR) by as much as 2-fold. Application of tumor bed boost by two different methods.
An extra radiotherapy dose to the tumor bed after breast-conserving surgery has benefits, but does not affect overall survival. We evaluated the necessity of a tumor bed boost after whole-breast radiotherapy for early-stage breast cancer after breast-conserving surgery and negative re-excision.

The Additional Irradiation Of The Tumor Bed In The Breast Cancer Conservative Treatment: What Techniques?
To quantify the difference between the area of brain irradiated using the posterior fossa boost (PFB) and tumor bed boost (TBB) in medulloblastoma, we studied 15 simulation radiographs of patients treated in our institution from 1990 and 1999.
