PURPOSE In patients who undergo resection of central nervous system metastases, whole brain radiotherapy (WBRT) is added to reduce the rates of recurrence and neurologic death. However, the risk of late neurotoxicity has led many patients to decline WBRT. We offered adjuvant stereotactic radiosurgery (SRS) or stereotactic radiotherapy (SRT) as an(More)
Breast Retraction Assessment (BRA) is an objective evaluation of the amount of cosmetic retraction of the treated breast in comparison to the untreated breast in patients who receive conservative treatment for breast cancer. A clear acrylic sheet supported vertically and marked as a grid at 1 cm intervals is employed to perform the measurements. Average BRA(More)
The evolution, time course, and dose response of gross and histologic changes associated with the acute and late changes of the skin are noted and a composite pathophysiologic operational model given. This model focuses the selection of the observations to be "scored" to assess the tolerance and cosmetic response of the skin and breast to different dose and(More)
PURPOSE To evaluate dose conformity, dose homogeneity, and dose gradient in helical tomotherapy treatment plans for stereotactic radiosurgery, and compare results with step-and-shoot intensity-modulated radiosurgery (IMRS) treatment plans. METHODS AND MATERIALS Sixteen patients were selected with a mean tumor size of 14.65 +/- 11.2 cm3. Original(More)
Arm lymphedema (ALE) was evaluated in 74 patients treated conservatively for breast cancer. ALE was defined based upon measurements performed upon 35 volunteer subjects who did not have and were never treated for breast cancer. Multiple variable statistical analysis of 74 breast cancer patients revealed that age at diagnosis was the most important factor(More)
We evaluated the relative usefulness of two observer-based scales commonly employed to assess the cosmetic outcome of patients treated by breast-preserving techniques for breast cancer. We asked 44 volunteer observers to employ one or the other scale to assess cosmetic outcome in a series of 14 projected color photographs of frontal views of treated(More)
Breast edema was evaluated in 45 patients with Stage I or II breast cancer (including two with simultaneous, bilateral disease), who were treated by breast-preserving treatment approaches. Multiple variable statistical analysis revealed that bra cup size was the only factor significantly related to the appearance of breast edema. Breast edema occurred in 3(More)
Four patients with metastases to the brain were treated by high-dose fractionated radiation therapy. In all four cases, a complete response and prolonged disease-free survival could be documented. Unlike the standard therapy for such patients (i.e., craniotomy and postoperative irradiation), high-dose fractionated radiation therapy carries no operative risk(More)
A retrospective study was performed to determine the value of pathological evaluation of inked primary tumor specimen margins in the local control of patients with stage I and II breast cancer. In 150 patients with 153 invasive breast cancers, treatment involved surgical resection of the primary tumor, pathological determination of tumor-free inked specimen(More)
PURPOSE To compare step-and-shoot intensity-modulated radiation therapy (SAS-IMRT) and helical tomotherapy (Tomo) dosimetry plans for patients who have received adjuvant radiation therapy for retroperitoneal sarcomas (RSTS). METHODS AND MATERIALS A retrospective review was performed for seven patients who received either SAS-IMRT or Tomo as adjuvant(More)
