  • Neoadjuvant chemotherapy with high-dose ifosfamide, high-dose methotrexate, cisplatin, and doxorubicin for patients with localized osteosarcoma of the extremity: A joint study by the Italian and Scandinavian Sarcoma Groups
  • 2005
  • Ingår i: Journal of Clinical Oncology. - American Society of Clinical Oncology. - 1527-7755. ; 23:34, s. 8845-8852

    • Purpose To explore the effect of high-dose ifosfamide in first-line treatment for patients <= 40 years of age with nonmetastatic osteosarcoma of the extremity. Patients and Methods From March 1997 to September 2000, 182 patients were evaluated. Primary treatment consisted of two blocks of high-dose ifosfamide (15 g/m(2)), methotrexate (12 g/m(2)), cisplatin (120 mg/m(2)), and doxorubicin (75 mg/m(2)). Postoperatively, patients received two cycles of doxorubicin (go mg/m(2)), and three cycles each of high-dose ifosfamide, methotrexate, and cisplatin (120 to 150 mg/m(2)). Granulocyte colony-stimulating factor support was mandatory after the high-dose ifosfamide/cisplatin/doxorubicin combination. Results No disease progression was recorded during primary chemotherapy, 164 patients (92%) underwent limb-salvage surgery, four patients (2%) underwent rotation plasty, and 11 patients (6%) had limbs amputated. Three (1.6%) patients died as a result of treatment-related toxicity, and one died as a result of pulmonary embolism after pathologic fracture. Grade 4 neutropenia and thrombocytopenia followed 52% and 31% of all courses, respectively, and mild to severe nephrotoxicity was recorded in 19 patients (10%). The median received dose-intensity compared with protocol was 0.82. With a median follow-up of 55 months, the 5-year probability of event-free survival was 64% (95% CI 57% to 71%) and overall survival was 77% (95% CI 67% to 81%), whereas seven patients (4%) experienced local recurrence. Conclusion The addition of high-dose ifosfamide to methotrexate, cisplatin, and doxorubicin in the preoperative phase is feasible, but with major renal and hematologic toxicities, and survival rates similar to those obtained with four-drug regimens using standard-dose ifosfamide. Italian Sarcoma Group/Scandinavian Sarcoma Group study I showed that in a multicenter setting, more than 90% of patients with osteosarcoma of the extremity can undergo conservative surgery.

  • Monitoring referral and treatment in soft tissue sarcoma: study based on 1,851 patients from the Scandinavian Sarcoma Group Register
  • 2001
  • Ingår i: Acta Orthopaedica Scandinavica. - Taylor & Francis. - 0001-6470. ; 72:2, s. 150-159
  • Tidskriftsartikel (refereegranskat)abstract
    • This report is based on 1.851 adult patients with soft tissue sarcoma (STS) of the extremities or trunk wall diagnosed between 1986 and 1997 and reported from all tertiary referral centers in Norway and Sweden. The median age at diagnosis was 65 years and the male-to-female ratio was 1.1:1. One third of the tumors were subcutaneous, one third deep, intramuscular and one third deep, extramuscular. The median size was 7 (1-35) cm and 75% were high grade (III-IV). Metastases at presentation were diagnosed in 8% of the patients. Two thirds of STS patients were referred before surgery and the referral practices have improved during the study. The preoperative morphologic diagnosis was made with fine-needle aspiration cytology in 81%, core-needle biopsy in 9% and incisional biopsy in 10%. The frequency of amputations has decreased from 15% in 198688 to 9% in 1995-1997. A wide surgical margin was achieved in 77% of subcutaneous and 60% of deep-seated lesions. Overall, 24% of operated STS patients had adjuvant radiotherapy. The use of such therapy at sarcoma centers increased from 20% 1986-88 to 30% in 1995-97. Follow-up has been reported in 96% of the patients. The cumulative local recurrence rate was 0.20 at 5 years and 0.24 at 10 years. The 5-year metastasis-free survival rate was 0.70.

  • Computed tomography of pulmonary metastases from osteosarcoma: The less poor technique. A study of 51 patients with histological correlation
  • 2001
  • Ingår i: Annals of Oncology. - Oxford University Press. - 1569-8041. ; 12:11, s. 1601-1604
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The purpose is to evaluate the accuracy of computed tomography (CT) in the pulmonary staging of osteosarcoma. Patients and methods: Fifty-one patients presenting with osteosarcoma and at initial CT considered metastatic to the chest had lung surgery. Two teams of two senior radiologists independently reviewed all CT examinations. Their results were compared to the histological studies. Results: One hundred nineteen CT's were reviewed. The 2 teams found 247 and 268 nodules on the initial, and 143 and 146 nodules on the preoperative CT. Histological studies confirmed metastatic nodules in 29 patients. Two hundred four nodules were excised and studied. One hundred nine were metastases. The 22 patients without metastases had 53 negative nodules removed. In the 29 patients with metastases, 151 nodules were removed, and 42 were non-metastatic. The positive predictive value was 53% with regard to 'nodules', and 57% with regard to 'patients'. Only 4 out of 13 patients with one nodule at surgery were metastatic, but all patients with more than 7 nodules were metastatic. The 46 cases with several available CT's, showed that no change in the number of nodules was more frequent in benign lesions. Other criteria revealed no significant difference. Conclusion: CT positive predictive value is limited, but as surgery is the only way to cure metastatic patients, CT will still be used as the reference technique until a more specific approach can be found.

  • Scandinavian Sarcoma Group Osteosarcoma Study SSG VIII: prognostic factors for outcome and the role of replacement salvage chemotherapy for poor histological responders
  • 2003
  • Ingår i: European Journal of Cancer. - Elsevier. - 1879-0852. ; 39:4, s. 488-494
  • Tidskriftsartikel (refereegranskat)abstract
    • From 1990 to 1997, 113 eligible patients with classical osteosarcoma received neo-adjuvant chemotherapy consisting of high-dose methotrexate, cisplatin and doxorubicin. Good histological responders continued to receive the same therapy postoperatively, while poor responders received salvage therapy with an etoposide/ifosfamide combination. With a median follow-up of 83 months, the projected metastasis-free and overall survival rates at 5 years are 63 and 74%, respectively. Independent favourable prognostic factors for outcome were tumour volume < 190 ml, 24-h serum methotrexate > 4.5 muM and female gender. The etoposide/ifosfamide replacement combination did not improve outcome in the poor histological responders. In conclusion, this intensive multi-agent chemotherapy results in > 70% of patients with classical osteosarcoma surviving for 5 years. The data obtained from this non-randomised study do not support discontinuation and exchange of all drugs used preoperatively in histological poor responders. As observed in previous Scandinavian osteosarcoma studies, female gender appears to be a strong predictor of a favourable outcome. (C) 2003 Elsevier Science Ltd. All rights reserved.

  • Teenagers and young adults with cancer in Europe: from national programmes to a European integrated coordinated project.
  • 2015
  • Ingår i: European Journal of Cancer Care. - John Wiley and Sons Inc.. - 1365-2354.
  • Tidskriftsartikel (refereegranskat)abstract
    • Over 14 000 patients aged 15-24 are estimated to be diagnosed with cancer in the European Union (EU) each year. Teenagers and young adults (TYA) often fall down gaps between children's and adults cancer services. The specific challenges of providing optimal care to them are described, but we present a summary of recent progress. Progress to overcome these challenges is happening at different rates across Europe. We summarise the European national projects in this field but more recently we have seen the beginnings of European coordination. Within the EU 7th Funding Programme (FP7) European Network for Cancer Research in Children and Adolescents programme (ENCCA), a specific European Network for Teenagers and Young Adults with Cancer has held a series of scientific meetings, including professionals, patients and caregivers. This group has proposed unanswered research questions and agreed key features of a high-quality service that can improve outcomes for TYA with cancer, including the primacy of collaboration between adult and paediatric services to eliminate the gap in the management of TYA with cancer.

  • Consequences of local recurrence of soft tissue sarcoma : 205 patients from the Scandinavian Sarcoma Group register
  • 2000
  • Ingår i: Acta Orthopaedica Scandinavica. - Taylor & Francis. - 0001-6470. ; 71:5, s. 488-495
  • Tidskriftsartikel (refereegranskat)abstract
    • From the Scandinavian Sarcoma Group Register, information on 1,224 surgically-treated patients with soft tissue sarcoma (STS) of the extremity or trunk wall, diagnosed between 1987 and 1995, was collected. 205 patients, one third of whom were referred to a center with a local recurrence, had a total of 284 local recurrences. This analysis describes the treatment for these local recurrences, complications and risk of further recurrences. 169 patients were surgically treated for their first local recurrence. An intralesional or marginal margin was achieved in 110 of these patients, 59 of whom were also given radiotherapy. 54 of the 169 patients had a second local recurrence. The second local recurrence rate was 0.50 if the first local recurrence had been treated with only surgery with a marginal margin, compared to 0.28 if treated with surgery with a marginal margin and radiotherapy or with a wide margin (p = 0.0008). In extremity STS, the crude amputation rate for local recurrences was 0.22 (31 of 142) - i.e., higher than for primary tumors 0.09 (96 of 1065) (p < 0.0001). A high local recurrence rate after treatment outside of sarcoma centers has earlier been shown. We conclude that the consequences of local recurrence in terms of morbidity and costs justifies referral of STS patients for multidisciplinary evaluation and multimodality treatment.

  • Local recurrence of deep-seated, high-grade, soft tissue sarcoma: 459 patients from the Scandinavian Sarcoma Group Register
  • 2001
  • Ingår i: Acta Orthopaedica Scandinavica. - Taylor & Francis. - 0001-6470. ; 72:2, s. 160-166
  • Tidskriftsartikel (refereegranskat)abstract
    • This study was based on 459 adult patients with deep, high-grade, soft tissue sarcoma of extremities or trunk wall reported to the Scandinavian Sarcoma Group Register (1986-1993). All patients had their definitive surgery for primary tumor at a sarcoma center. The median follow-up was 7.5 (3-12) years. 204 patients are still alive. 68 patients had amputations and 391 underwent limb-sparing surgery. Among 183 patients with intralesional or marginal margins after limb-sparing surgery, 65% had postoperative radiotherapy and 9% of the 198 patients with wide margins. The local recurrence rate after limb-sparing surgery was 26%. The rate with an intralesional or marginal margin was 39% without postoperative radiotherapy versus 24% when radiotherapy was given. It was 25% after a wide margin, and no recurrences were noted among the 10 patients with a compartmental surgical margin. Among patients with a wide margin, a subset fulfilling criteria for a myectomy was defined. The local recurrence rate was 26% among these 62 and there was no advantage of myectomy over other wide margins. More radical surgical margins would improve the local recurrence rate, but this can hardly be achieved in center-operated patients without increasing the amputation rate. Instead, increased use of radiotherapy in all patients with inadequate margins, and to a larger extent in those with wide margins will improve local control.
