Telangiectatic osteosarcoma (TOS) is a rare subtype of osteosarcoma. We review our experience to characterize its prevalence, treatment, relapse and survivorship at long term follow-up. Eighty-seven patients aged from 4 to 60 years (mean 20 years), were treated from 1985 to 2008. Lesions affected the femur (38), humerus (20), tibia (19), fibula (4), pelvis (3), foot (2) and radius (1). Eight patients had metastatic disease at diagnosis. Seventy-eight patients were treated with neoadjuvant chemotherapy with three or more drugs according to different protocols, nine had surgery as first treatment. Limb salvage surgery was performed in 71 cases, amputation in 14 and rotationplasty in one. One patient died before surgery. Prognostic factors were evaluated with Kaplan-Meier analysis.Introduction
Methods
To present selective arterial embolization with N-2-butyl Cyanoacrylate for the palliative and/or adjuvant treatment of painful bone metastases not primarily amenable to surgery. From January 2003 to December 2009, 243 patients (148 men and 95 women; age range, 20–87 years) with painful bone metastases were treated with N-2-butyl Cyanoacrylate. Overall, 309 embolizations were performed; 56 patients had more than one embolization. Embolizations were performed in the pelvis (168 procedures), in the spine (83 procedures), in the upper limb (13 procedures), in the lower limb (38 procedures) and in the thoracic cage (21 procedures). Primary cancer included urogenital, breast, gastrointestinal, thyroid, lung, musculoskeletal, skin, nerve and unknown origin. Renal cell carcinoma was the most commonly treated tumor. In all patients, selective embolization was performed by transfemoral catheterization.Aim
Material and Methods
There is doubt regarding resection compared to curettage for pelvic metastases. Previous studies have reported that curettage is associated with decreased survival compared with wide resection, and have justified a radical surgical approach to achieve pain palliation and tumor control. To evaluate the role of wide en bloc resection compared to curettage/marginal resection for patients with pelvic metastases. The rationale was that wide resection does not improve survival even in patients with solitary pelvic metastases.Background
