KP1019 [indazolium trans-[tetrachlorobis(1H-indazole)ruthenate (III)] (FFC14A) is a metal complex with promising anticancer activity. Since chemoresistance is a major obstacle in chemotherapy, this study investigated the influence of several drug resistance mechanisms on the anticancer activity of KP1019. Here we demonstrate that the cytotoxic effects of(More)
Strategies for extracorporeal shockwave therapy in calcifying tendinitis of the rotator cuff vary concerning quantity of sessions and doses. The purpose of this prospective pilot study was to determine the difference between the outcome of a single high-dosage extracorporeal shockwave therapy and two sessions of low-dosage extracorporeal shockwave therapy.(More)
Based on neoadjuvant chemotherapy, the prognosis of osteosarcoma patients has improved dramatically. However, due to therapy resistance in patient subgroups, the development of new treatment strategies is still of utmost importance. The aim of our study was to test the effects of the nitrogen-containing bisphosphonate zoledronic acid (ZOL) on osteosarcoma(More)
BACKGROUND Enhanced signalling via the epidermal growth factor receptor (EGFR) is a hallmark of multiple human carcinomas. However, in recent years data have accumulated that EGFR might also be hyperactivated in human sarcomas. Aim of this study was to investigate the influence of EGFR inhibition on cell viability and its interaction with chemotherapy(More)
BACKGROUND Primary bone or soft tissue tumors of the femur sometimes present with severe and extensive bone destruction, leaving few limb-salvage options other than total femur replacement. However, there are few data available regarding total femur replacement and, in particular, regarding implant failures. QUESTIONS/PURPOSES We asked: (1) What are the(More)
BACKGROUND Endoprosthetic replacement in children following resection of a malignant bone tumor still is controversial because of the high number of reoperations. The aim of this study was to evaluate the long-term outcome with respect to limb-lengthening potential, satisfaction rate, and complications after implantation of extendible devices. METHODS(More)
BACKGROUND Tumor spread to the knee joint or skip metastasis to the adjacent bones of the knee require reconstruction with combined distal femur and proximal tibia replacements. The literature on implant survival and failure modes with this type of reconstruction is sparse. The goals of this study were to determine the implant survival, the different(More)
AIMS Few studies dealing with chondrosarcoma of the pelvis are currently available. Different data about the overall survival and prognostic factors have been published but without a detailed analysis of surgery-related complications. We aimed to analyse the outcome of a series of pelvic chondrosarcomas treated at a single institution, with particular(More)
PURPOSE The aim of this study was the evaluation of possible outcome differences of patients undergoing two-stage hip exchange with antibiotic-loaded spacers, compared to patients without an interim spacer implantation. METHODS We evaluated 46 patients undergoing two-stage hip revision surgery. Twenty-five patients received an interim ALS. Additional to a(More)
