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.

Despite local treatment with systemic chemotherapy in Ewing’s sarcoma family tumours (ESFT), patients with detectable metastases at presentation have a markedly worse prognosis than those with apparently localised disease. We investigated the clinical, pathological and laboratory differences in 888 patients with ESFT, 702 with localised disease and 186 with overt metastases at presentation, seen at our institution between 1983 and 2006.

Multivariate analyses showed that location in the pelvis, a high level of serum lactic dehydrogenase, the presence of fever and a short interval between the onset of symptoms and diagnosis were indicative of metastatic disease. The rate of overt metastases at presentation was 10% without these four risk factors, 22.7% with one, 31.4% with two, and 50% for those with three or four factors. We concluded that in ESFT the site, the serum level of lactic dehydrogenase, fever, and the interval between the onset of symptoms and diagnosis are indicators of tumours having a particularly aggressive metastatic behaviour.

The role of radiotherapy and/or surgery in the local treatment of Ewing’s sarcoma has still to be determined. The outcome of Ewing’s sarcoma may differ according to its location and a selection bias towards surgery limits the ability to compare methods of local treatment. We have carried out a retrospective review of 91 consecutive patients treated for non-metastatic Ewing’s sarcoma of the femur. They received chemotherapy according to four different protocols. The primary lesion was treated by surgery alone (54 patients), surgery and radiotherapy (13) and radiotherapy alone (23). One was treated by chemotherapy alone.

At a median follow-up of ten years, 48 patients (53%) remain free from disease, 39 (43%) have relapsed, two (2%) have died from chemotherapeutic toxicity and two (2%) have developed a radio-induced second tumour.

The probability of survival without local recurrence was significantly (p = 0.01) higher in patients who were treated by surgery with or without radiotherapy (88%) than for patients who received radiotherapy alone (59%). The five- and ten-year overall survival rates were 64% and 57%, respectively. Patients who were treated by surgery, with or without radiotherapy, had a five- and ten-year overall survival of 64%. Patients who received only radiotherapy had a five- and ten-year survival of 57% and 44%, respectively.

Our results indicate that in patients with Ewing’s sarcoma of the femur, better local control is achieved by surgical treatment (with or without radiotherapy) compared with the use of radiotherapy alone. Further studies are needed to verify the impact of this strategy on overall survival.

We have studied 560 patients with osteosarcoma of a limb, who had been treated by neoadjuvant chemotherapy, in order to analyse the incidence of local and systemic recurrence according to the type of surgery undertaken. Of these, 465 patients had a limb-salvage procedure and 95 amputation or rotationplasty.

At a median follow-up of 10.5 years there had been 225 recurrences. The five-year disease-free survival and overall survival rates were 60.7% and 68.5%, respectively, with no significant difference between patients undergoing amputation and those undergoing resection. The incidence of local recurrence was the same for patients treated by either amputation or limb salvage and correlated significantly with the margins of surgical excision and the histological response to chemotherapy. The outcome for patients with a local recurrence was significantly worse than for those who had recurrent disease with metastases only.

We conclude that limb-salvage procedures are relatively safe in osteosarcoma treated by neoadjuvant chemotherapy. They should, however, only be performed in institutions where the margins of surgical excision and the histological response to chemotherapy can be accurately assessed. If the margins are inadequate and the histological response to chemotherapy is poor an immediate amputation should be considered.
