Neoadjuvant stereotactic ablative radiotherapy (SABR) for soft tissue sarcomas of the extremities.

Background: Soft tissue sarcomas (STS) comprise a diverse group of mesenchymal malignancies that require multidisciplinary care. Although surgery remains the primary form of treatment for those with localized disease, radiation therapy (RT) is often incorporated either in the neo- or adjuvant setting. Given the development of modern RT techniques and alternative dosing schedules, stereotactic ablative radiotherapy (SABR) has emerged as a promising technique.

UNCEMENTED ARTHROPLASTY AFTER HIP METASTATIC DISEASE AND MULTIPLE MYELOMA.

Objective: To describe a case series using a combination of narrative, graphical exploratory analysis and Bayesian Network modeling

Methods: Case series with 34 patients undergoing uncemented and hybrid arthroplasty procedures secondary to hip pain or fracture secondary to metastatic disease or multiple myeloma

Results: The most common tumors included gastrointestinal, multiple myeloma and breast cancer. Most devices were total arthroplasty (n = 16, 84.2%) rather than partial and uncemented arthroplasty (n = 12, 63.

GCT: What happened after 10 years of curettage and cement? Retrospective study of 46 cases.

Objective: To compare the functional outcome of patients with and without arthrosis, and to determine whether the development of arthrosis is related to the distance of the tumor from the subchondral bone.

Methods: Forty six patients treated for Giant-cell tumor (GCT) between 1975 and 1999 met inclusion criteria. GCT was diagnosed by percutaneous biopsy and confirmed after resection, in all cases.

Validation of the Brazilian version of the musculoskeletal tumor society rating scale for lower extremity bone sarcoma.

Background: The Musculoskeletal Tumor Society (MSTS) rating scale is an English-language instrument used worldwide to assess functional evaluation of patients with musculoskeletal cancer. Despite its use in several studies in English-speaking countries, its validity for assessing patients in other languages is unknown. The translation and validation of widely used scales can facilitate the comparison across international patient samples.
