PURPOSE Surgical clips are used as a target for postoperative breast radiotherapy, and displacement of surgical clips would result in inaccurate delivery of radiation. We investigated the displacement range of surgical clips in the breast during postoperative radiotherapy following breast-conserving surgery. METHODS A total of 178 patients who received breast-conserving surgery and postoperat...

Postoperative radiotherapy for breast cancer is known to substantially reduce the risk of locoregional recurrence, both when given after mastectomy and after breast-conserving surgery. Recent reports [cited below] suggest that radiotherapy following mastectomy may also have a beneficial impact on survival, and the article by Vinh-Hung et al. (1), published in this issue of the Journal, further ...

Introduction: Breast conserving radiotherapy is one of the most common procedures performed in any radiation oncology department. A tangential parallel-opposed pair is usually used for this purpose. This technique is performed using 2D or 3D treatment planning systems. The aim of this study was to compare 2D treatment planning with 3D treatment planning in tangential irradiation in breast conse...

BACKGROUND: Breast angiosarcoma is a rare disease occurring as primary tumour or secondary to lymphoedema or radiotherapy. The more frequent use of breast-conserving therapy and radiotherapy for breast carcinoma explains the increasing diagnosis of these tumours. CASE REPORT: We report a case of a breast epithelioid angiosarcoma which metastasized to the contralateral axillary lymph node, occur...

Centrally located tumours have long been considered to be more serious, multifocal and more likely to recur. In fact, this is not the case; the only real problem is ensuring that the breast is preserved with a “normal” form following breast-conserving surgery and adjuvant radiotherapy. As with more peripheral tumours, central tumours may also benefi t from breast-conserving surgery. Several tec...

Most breast cancer recurrences occur in the surgical scars or within other quadrants of the same breast. Isolated tumour recurrence occurring in the nipple after breast-conserving surgery and radiotherapy is extremely unusual. The reason for this is unknown, but is speculated to be due to involved surgical margins or an occult involvement of the nipple-areolar complex in a breast cancer of the ...

Breast-conserving surgery followed by whole-breast irradiation is the standard local therapy for early breast cancer. The international discussion of reduced importance of wider tumor-free resection margins than "tumor not touching ink" leads to the development of five principles in targeted oncoplastic breast surgery. IORT improves local recurrence risk and diminishes toxicity since there is l...

Background:  After breast conserving surgery, most recurrences occur around the primary tumor site. This justifies the use of boost radiotherapy to the primary site of tumor. Surgical scar is not always a good surrogate for the location of the lumpectomy cavity. The aim of this study was to evaluate ultrasonic guidance for detection of the lumpectomy cavity after breast conserving surgery ...
