Aim

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.

Method

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.

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.

Prolonged survival have been reached in the last two decades in patients with Ewing’s sarcoma due to combination of chemotherapy and radiotherapy.

We report the analysis of 493 patients treated according to 4 different protocols in 23 years (Jan1983- Dec 2006).Aim of this study was to evaluate the occurrence of late toxicities as Second Malignant Neoplasms (SMN), Cardiomyopathies and sterility.

Methods: We reviewed our database to find out all those patients aged from 1 to 40 yrs with localized Ewing’s sarcoma who were treated with chemotherapy according to 4 different protocols from 1983 to December 2006. Data were updated at Dec 2008

Results: 493 patients had adequate follow up and meet the eligibility criteria. Median age was 16 yrs (1–40) female/male: 183/310.Median overall survival 69 ms (4–302).220 patients died and 273 are alive. 44 pts received HDCT + PBSCR.Eleven SMN were found : 2 AMLeukemia, 2 parotid adenocarcinoma, 1 melanoma, 1 thyroid cancer and 5 radioinduced osteosarcoma. The interval between Ewing’s sarcoma diagnosis and leukaemia diagnosis was shorter then interval between Ewing’s sarcoma and RT osteosarcoma. Six patients reported a Cardiomyopathy : in 4 cases it was mild and pts are well compensated,2 patients needed heart transplant,. One of these two pts received also a kidney transplant due to chronic renal failure due to previous chemotherapy. Fertility: 17 women became pregnant after chemotherapy, 20 women experienced postTx amenorrea: 7 pts received RT in pelvic area, 9 did HDCT, 3 pts were over 30 yrs old. 9 male became father. 8 male patients did sperm analysis 3 azospermia, 4 oligospermia and 1 normal sperm count. No congenital abnormalities in offsprings were reported.

Conclusions: In this casuistic the Cumulative Risk to have a SMN at 5 yrs is 1.8% and 2.9% at 10 yr. The SMN cumulative incidence in Ewing’s sarcoma seems to be lower then in our previous casistic in osteosarcoma patients (ASCO 2006).

EUROpean Bone Over 40 Sarcoma Study (EURO-B.O.S.S.) is the first prospective multicenter international study for patients 41–65 year old with high-grade bone sarcoma

Patients with HG Osteosarcoma (OS), HG sarcoma NOS (S), Fibrosarcoma, MFH, Leiomyosarcoma, Dedifferentiated Chondrosarcoma (DCh) were included. Chemotherapy: Combinations of cisplatin/doxorubicin (CDP 100mg/m2/ADM 60mg/m2), ifosfamide/CDP(IFO 6g/m2/CDP 100mg/m2) and IFO/ADM (IFO 6g/m2/ADM 60mg/m2) were repeated three times (9 cycles). Surgery was planned after 3 cycles. Methotrexate (8g/m2) was postoperatively added in poor responders. Immediate surgery was allowed and 9 cycles with CDP, ADM, IFO were postoperatively given.

At December 2007, 140 patients were registered (median age 51 years). OS (51%), S (16%), and DCh (11%) were the more frequent histotypes. Synchronous metastases in 30 (21%) patients, central location of tumor in 45(32%).Surgical complete remission (SCR) was achieved in 84% of patients, (localized 91%, meta-static 37%) without difference among the histology groups. One surgical-related and one chemotherapy-related death were reported.

Grade4 WBC and PLT incidence was 55% and 17%.Renal toxicity and peripheral neurotoxicity were reported in 16% and 20% of patients. With a median follow-up of 25 months (4–68) 3 year OS was 58% (95%CI 48–68%) [7% (95%CI 0–19%) without SCR]. In patients with SCR, 3-year OS and EFS were 46% (95%CI 9–83%) and 0% in case of synchronous metastases and 69% (95%CI58–80%) and 45% (95%CI33–57%) for localized patients; 50% (95%CI 29–71%) and 40% (95%CI 20–59%) for patients with central tumor, 73% (95%CI61–85%) and 44% (95%CI31–57%) for those with extremity tumor; 68% (95%CI 52–83%) and 46% (95%CI 32–54%) for OS, 64% (95%CI 42–85%) and 48% (95%CI 25–71%) for S, 48% (95%CI 13–82%) and 27% (95%CI 1–54%) for DCh.

The protocol is feasible, but the chemotherapy-related toxicity is remarkable. Surgical complete remission is the main factor influencing survival. Central location and synchronous metastases are negative prognostic factors, but 50% 3-year OS can be achieved with aggressive local and systemic treatment. Osteosarcoma and high-grade sarcoma NOS benefit from chemotherapy more than patients with dedifferentiated chondrosarcoma.

Osteosarcoma is the most common second malignancy seen in retinoblastoma survivors. Risk of developing osteosarcoma in this group is estimated approximately 500 times higher than the general population. Prognosis in this setting has been reported significantly worse than conventional osteosarcoma despite multimodal management. Purpose of this study was to evaluate clinical features, molecular aspects and outcome of treatment in this subgroup of osteosarcoma patients.

Between 1985 and 2004, from a total of about 1100 osteosarcomas, 7 survivors of retinoblastoma developing high-grade osteosarcoma as second malignancy presented at the authors’ Institution. Retrospective study was undertaken to analyze presentation, tissue expression of RB1, P53, PGP and DHFR, treatment and outcome of both retinoblastoma and osteosarcoma.

Retinoblastoma was bilateral in 5 cases and unilateral in two. All the patients had been treated with a combination of surgery +/− chemotherapy +/− radiation.

None of them had evidence of retinoblastoma at the time of second malignancy diagnosis. Average age at diagnosis of osteosarcoma was 14 years (9–17 years), mean interval between the two malignancies was 155 months. All the osteosarcomas were in the appendicular skeleton, all but one around the knee. Molecular analysis showed defective RB1 gene in all cases All the seven patients received contemporary multimodal management for osteosarcoma. All but one patient died of osteosarcoma within 30 months from diagnosis. The living patient had local recurrence 9 years after limb salvage and is currently disease free following amputation.

Prognosis of osteosarcoma in retinoblastoma patients remains poor as compared to conventional high grade osteosarcoma despite multimodal management. No obvious correlation was found between poor prognosis and P53, PGP and DHFR expression.
