  Objective Stereotactic body radiation therapy (SBRT) is an attractive option for prostate cancer due to its short treatment duration and cost. In this report, we compare the efficacy and toxicity outcomes of prostate cancer patients treated with SBRT to those who received intensity-modulated radiation therapy (IMRT). Methods Two hundred sixty-three patients with localized prostate adenocarcinoma...

  Objective Few studies have evaluated re-irradiation of lung cancer recurrences with stereotactic body radiotherapy (SBRT). This study evaluates outcomes with SBRT re-irradiation for recurrent lung cancer. Methods Two hundred and seventy-eight patients treated with SBRT for lung cancer were retrospectively reviewed. Of those, 26 patients with 29 tumors were re-irradiated with SBRT...

  To examine the fractionation effect of stereotactic body radiation therapy with a heterogeneous dose distribution.Derived from the linear quadratic formula with measurements from a hypothetical 2-cm radiosurgical tumor, the threshold percentage was defined as (α/β tissue /α/β tumor ), the balance α/β ratio was defined as (prescription dose/tissue tolerance*α/β tumor ), and...
  Stereotactic body radiation therapy for the primary treatment of localized prostate cancer

  Objective The low alpha/beta ratio of prostate cancer suggests that hypofractionated schemes of dose-escalated radiotherapy should be advantageous. We report our experience using stereotactic body radiation therapy (SBRT) for the primary treatment of prostate cancer to assess efficacy and toxicity. Methods From 2007 to 2010, 70 patients (51 % low risk, 31 % intermediate risk, and 17 % high risk)...

  Background. Cutaneous angiosarcoma (AS) is a rare, often multicentric vascular tumor of the head and neck region with a rather poor prognosis. The original clinical size of the tumor rarely correlates to the degree of microscopic tissue invasion. Treatment by surgical excision sometimes requires very wide excision. Treatment by radiation or electron beam appears less mutilating but its efficacy is...
  A cost-effectiveness and cost-utility analysis of radiosurgery vs. resection for single-brain metastases

  Purpose: The median survival of well-selected patients with single-brain metastases treated with whole-brain irradiation and resection or radiosurgery is comparable, although a randomized trial of these two modalities has not been performed. In this era of cost containment, it is imperative that healt-care professionals make fiscally prudent decisions. The present environment necessitates a critical...
