This study evaluated the role of pulsed dose-rate (PDR) brachytherapy (BRT), delivered alone or as a boost to external beam radiotherapy, as adjuvant therapy for the local control of soft tissue sarcomas of the extremities and skeletal muscles of the trunk that have undergone surgical treatment. ⋯ PDR interstitial BRT for soft tissue sarcoma is an effective, well-tolerated adjuvant radiation treatment that offers several practical advantages, among which are low acute and late toxicity with maximum normal tissue and critical structure sparing and overall shorter radiotherapy and hospital stay.

Sentinel lymph node biopsy (SLNB) is a safe and accurate axillary staging procedure for patients with primary operable breast cancer. An increasing proportion of these patients undergo breast-conserving surgery, and 5% to 15% will develop local relapses that necessitate reoperation. Although a previous SLNB is often considered a contraindication for a subsequent SLNB, few data support this concern. ⋯ Second SLNB after previous SLNB is technically feasible and likely effective in selected breast cancer patients. A larger population and longer follow-up are necessary to confirm these preliminary data.
