Aim. Ten years ago at the EMSOS 2000 meeting we have presented our experience concerning the non-surgical treatment of stage IIB osteosarcoma of extremities. The purpose of study was to evaluate long-term results and complications related to this non-standard and controversial treatment modality. Methods. Since 1988 definitive radiation gamma therapy (RT) in the median dose of 60 Gy was administrated to 36 patients who refused surgery after preoperative chemotherapy. Until 1999 induction consisted in 3-5 cycles of intra-arterial doxorubicin (DOX) 75 mg/m2 or cis-platin (CDDP) 120 mg/m2. Since 2000 induction comprised 4 cycles of DOX 90 mg/m2+CDDP 120 mg/m2 intra-arterially. Tumour response before local treatment was assessed non-invasively by means of X-ray, CT, MRI, angiography, 3-phase bone scans and alkaline phosphatase measurement. The end-points were overall (OS), metastases free (MFS) and local progression free (LPFS) survival at 10 years. Results. OS, MFS and LPFS by Kaplan-Meier method were 48±9%, 51±9%, and 45±11% respectively. The outcome was significantly related to response assessed before RT. In 12 good responders OS, MFS and LPFS were 74±13%, 91±9%, and 69±19% respectively compared with 29±11%, 27±11%, and 34±13% in 24 non-responders, p- value 0.03, 0.003, 0.009, respectively. In 14 patients 5 years survival after local progression and delayed surgery was 38±10%. Median survival time after local relapse was 36 months. Two types of major complications were seen: 7 pathological fractures and one osteomyelitis. 21 patients (58%) remained with a functional limb until the last examination or death. Conclusions. Long-term results were higher than expected in this radioresistant tumour. In good responders to induction chemotherapy RT could be an option for local treatment. Majority of patients had a functional limb during and long time after treatment. Isolated late local relapses did not influence considerably systemic control

Aims

Ilium is the most common site of pelvic Ewing’s sarcoma (ES). Resection of the ilium and iliosacral joint causes pelvic disruption. However, the outcomes of resection and reconstruction are not well described. In this study, we report patients’ outcomes after resection of the ilium and iliosacral ES and reconstruction with a tibial strut allograft.

Aims

The incidence of bone metastases is between 20% to 75% depending on the type of cancer. As treatment improves, the number of patients who need surgical intervention is increasing. Identifying patients with a shorter life expectancy would allow surgical intervention with more durable reconstructions to be targeted to those most likely to benefit. While previous scoring systems have focused on surgical and oncological factors, there is a need to consider comorbidities and the physiological state of the patient, as these will also affect outcome. The primary aim of this study was to create a scoring system to estimate survival time in patients with bony metastases and to determine which factors may adversely affect this.

Aims

Time to treatment initiation (TTI) is generally defined as the time from the histological diagnosis of malignancy to the initiation of first definitive treatment. There is no consensus on the impact of TTI on the overall survival in patients with a soft-tissue sarcoma. The purpose of this study was to determine if an increased TTI is associated with overall survival in patients with a soft-tissue sarcoma, and to identify the factors associated with a prolonged TTI.
