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 tumour. In all patients, selective embolization was performed by transfemoral catheterization.Aim
Material and Methods
Patients treated with limb salvage surgery for bone sarcomas of the extremities (upper and lower) may have physical disability as a result of treatment. Goal of this study was to evaluate the quality of life after treatment (chemotherapy and conservative surgery) at long term. 208 patients resected for a bone sarcoma and with prosthetic reconstruction (45 in the upper and 163 in the lower limb) were evaluated. Assessment of results was done using the Karnofsky Scale (K.S.). Patients were followed in the clinic and functional results assessed according to the Musculoskeletal Tumour Society (MSTS) system. Moreover the Toronto Extremity Salvage Score questionnaire (TESS) was mailed to 144 patients.Aim
Method
Prognostic stratification of patients with non-metastatic osteosarcoma may improve the clinical management and the design of clinical trials. Data from 773 patients [median age 15 years (3-40)] treated at our Institute from 1983 to 2000 with high-dose methotrexate, cisplatin, doxorubicin and ifosfamide (neoadjuvant chemotherapy) were analyzed. After multivariate analysis including age, site, tumour volume (cut-off 200 mL), serum LDH and Alkaline Phosphatase (SAP), histology (osteoblastic and chondroblastic vs others), high LDH and SAP, osteoblastic and chondroblastic histotypes resulted independent prognostic factors of DFS. Patients were grouped according to a score from 0 (absence) to 3 (one to 3 adverse factors). The scoring system was implemented by the addition of PgP expression and grade of chemotherapy-induced necrosis. A score of 0, 1, 2, 3 was given to 14%, 38%, 32% and 16% of patients respectively.10-year DFS was 80% (95%CI 72-89) for score of 0, 58% (95%CI 52-64) for 1, 53% (95%CI 46-59) for 2 and 40% (95%CI 32-50) for 3 (p= 0.001). PgP expression (168 patients) identified patients with 100% probability of DFS (score of 0 and negative PgP) and patients with 18% (95%CI 52-64) DFS (score of 3 and positive PgP). Good (GR) and poor responder (PR) patients had the same probability of DFS in case of score of 0 [GR82% (95% CI 72-91), PR79% (95% CI 65-93)] and score of 3 [GR43% (95% CI 32-55) PR36% (95% CI 21-51)]. Different probability of DFS in case of score of 1 [GR64% (95% CI 57-72) PR47% (95% CI 36-59)] and score of 2 [GR63% (95% CI 55-71) PR36% (95% CI 21-51)]. It is possible to stratify outcomes of patients with non metastatic osteosarcoma of the extremity by means of a simple score based on easily available clinical parameters. This scoring system is worth to be validated on larger series.
was to analyze infections after bone tumour surgery. 1463 patients treated from 1976 to 2007 were analized: 1036 with resection and prostheses in the lower limbs, 344 with resection and prostheses in the upper limbs, 83 with surgery for sacral tumours. Infections were analyzed for time of occurrence (“postoperative” in the first 4 weeks from surgery, “early” within 6 months, and “late” after 6 months), microbic agents, treatment, outcome.Aim
Method
Purpose of this study was to review a single Institution experience and results of management of extraskeletal osteosarcoma (OGS), with emphasis on the role of combined treatment consisting of surgery and adjuvant chemotherapy. Retrospective study of 48 patients observed 1966- 2007 was undertaken: 36 patients were managed at our Institution while 12 cases were consultations and not included in this study. Clinico-pathologic features and details of treatment of all 36 patients were correlated with outcome. Updated follow-up was available in all patients.Aim
Method
To evaluate outcome and complications of knee arthrodesis with a modular prosthetic system (MUTARS(r) Implantcast), as primary and revision implants in musculoskeletal oncology. Between 1975 and 2009, 24 prostheses were used for knee arthrodesis. Nineteen in oncologic cases: 6 osteosarcomas, chondrosarcoma, synovial sarcoma and metastatic carcinoma 3 each, 2 pigmented villonodular synovitis (PVNS), malignant fibrous hystiocitoma and giant cell tumour 1 each. Patients were grouped into: A) primary implants, B) revision implants. Group A included 9 patients: 8 arthrodeses after extra-articular resection with major soft tissue removal, 1 after primary resection following multiple excisions of locally recurrent PVNS. Group B included 15 patients: 12 arthrodeses for infection (5 infected TKAs, 7 infected megaprostheses), 2 for failures of temporary arthodesis with Kuntscher nail and cement, 1 for recurrent chondrosarcoma in previous arthrodesis.Aim
