ABSTRACT Background:
The effect of adjuvant chemotherapy on survival for resected soft-tissue sarcoma remains unknown. We investigated the effect of intensive adjuvant chemotherapy on survival in patients after resection of high-risk soft-tissue sarcomas.

In this multicentre randomised trial, patients with macroscopically resected, Trojani grade II-III soft-tissue sarcomas at any site, no metastases, performance status lower than 2 and aged between 16 and 70 years were eligible within 4 weeks of definitive surgery. Patients were randomly assigned to receive adjuvant chemotherapy or no chemotherapy (control group). Randomisation was done with a minimisation technique, stratified by hospital, site of primary tumour, tumour size, planned radiotherapy, and isolated limb perfusion therapy. Chemotherapy consisted of five cycles of doxorubicin 75 mg/m(2), ifosfamide 5 g/m(2), and lenograstim every 3 weeks. Patients in both groups received radiotherapy if the resection was marginal or the tumour recurrent. The primary endpoint was overall survival and analyses were done by intention to treat. The final results are presented. This trial is registered with, NCT00002641.

Between February, 1995, and December, 2003, 351 patients were randomly assigned to the adjuvant chemotherapy group (175 patients) or to the control group (176). 258 (73%) of 351 patients received radiotherapy, 129 in each group. Overall survival did not differ significantly between groups (hazard ratio [HR] 0·94 [95% CI 0·68-1·31], p=0·72) nor did relapse-free survival (HR 0·91 [0·67-1·22], p=0·51). 5-year overall survival rate was 66·5% (58·8-73·0) in the chemotherapy group and 67·8% (60·3-74·2) in the control group. Chemotherapy was well tolerated, with 130 (80%) of 163 patients who started it completing all five cycles. 16 (10%) patients had grade 3 or 4 fever or infection, but no deaths due to toxic effects were recorded.

Adjuvant chemotherapy with doxorubicin and ifosfamide in resected soft-tissue sarcoma showed no benefit in relapse-free survival or overall survival. Future studies should focus on patients with larger, grade III, and extremity sarcomas.

    • "The small number of patient treated with different antineoplastic agents does not allow any subgroup analysis. Our results are consistent with the results of the EORTC Soft Tissue and Bone Sarcoma Group trial, comparing adjuvant chemotherapy with five cycles of doxorubicin–ifosfamide with observation in 351 patients with intermediate and high-grade tumors, in which the 5 year DFS and OS were not statistically different among treatment arms [20]. A multicenter phase III randomized clinical trial (SARCGYN protocol ), comparing API (doxorubicin, ifosfamide, and cisplatin) chemotherapy regimen followed by RT versus RT alone for patients with stage I–III uterine sarcoma after definitive surgery was recently published by the French intergroup [24]: the authors found a statistical impact of adjuvant chemotherapy on DFS without impact on OS yet.

    ABSTRACT: Objective: About 50-60% of patients with stage I-II uterine leiomyosarcoma (ULMS), primarily treated with surgery, relapse and die from progressive disease. In this retrospective study we describe the impact of adjuvant chemotherapy in this subset of patients. Methods: 140 women treated from 1976 to 2011 were included in the study. Univariate and multivariate analysis were used to test the association of clinical features and adjuvant treatments with overall survival (OS) and disease-free survival (DFS). Results: 62 women did not receive any further treatment after hysterectomy, 14 had radiotherapy (RT), 52 chemotherapy and 12 chemo-radiotherapy. Chemotherapy based on doxorubicin and ifosfamide combination was used in 54 cases. After a median follow-up of 63months, 87 women (62%) have relapsed, and 62 (44%) have died. The vast majority of patients who relapsed had distant recurrences (72%). The 5year median DFS and OS were 43% and 64% respectively. After 5years of follow up 68.7% of women treated with chemotherapy (±RT) vs 65.6% of patients only observed were alive (p=0.521). In the univariate analysis no factors had a statistical impact on DFS, while number of mitosis (>20×10HPF), age (>60years) and adjuvant radiotherapy were found as negative prognostic factors for OS. In the multivariate analysis only mitosis and age remained significant for OS. Conclusion: Adjuvant chemotherapy was not associated with a significant survival benefit and should not be considered as standard of care for patients with stage I-II ULMS until randomized clinical studies will give further information.

    • "The role of chemotherapy in the treatment of high-risk sarcomas with curative intent remains controversial as several randomized trials and meta-analyses have reported conflicting results. In the adjuvant setting, two major phase III trials conducted by the EORTC (62771 and 62931) [42,43] have failed to show a significant benefit for overall survival with the addition of chemotherapy. While the first one reported at least a significant benefit in relapse-free survival, this result could not be confirmed in the latter one. "

    ABSTRACT: To report the results of a subgroup analysis of a prospective phase II trial focussing on radiation therapy and outcome in patients with extremity soft tissue sarcomas (STS). Between 2005 and 2010, 50 patients (pts) with high risk STS (size ≥ 5 cm, deep/extracompartimental location, grade II-III (FNCLCC)) were enrolled. The protocol comprised 4 cycles of neoadjuvant chemotherapy with EIA (etoposide, ifosfamide and doxorubicin), definitive surgery with IOERT, postoperative EBRT and 4 adjuvant cycles of EIA. 34 pts, who suffered from extremity tumors and received radiation therapy after limb-sparing surgery, formed the basis of this subgroup analysis. Median follow-up from inclusion was 48 months in survivors. Margin status was R0 in 30 pts (88%) and R1 in 4 pts (12%). IOERT was performed as planned in 31 pts (91%) with a median dose of 15 Gy, a median electron energy of 6 MeV and a median cone size of 9 cm. All patients received postoperative EBRT with a median dose of 46 Gy after IOERT or 60 Gy without IOERT. Median time from surgery to EBRT and median EBRT duration was 36 days, respectively. One patient developed a local recurrence while 11 patients showed nodal or distant failures. The estimated 5-year rates of local control, distant control and overall survival were 97%, 66% and 79%, respectively. Postoperative wound complications were found in 7 pts (20%), resulting in delayed EBRT (>60 day interval) in 3 pts. Acute radiation toxicity mainly consisted of radiation dermatitis (grade II: 24%, no grade III reactions). 4 pts developed grade I/II radiation recall dermatitis during adjuvant chemotherapy, which resolved during the following cycles. Severe late toxicity was observed in 6 pts (18%). Long-term limb preservation was achieved in 32 pts (94%) with good functional outcome in 81%. Multimodal therapy including IOERT and postoperative EBRT resulted in excellent local control and good overall survival in patients with high risk STS of the extremities with acceptable acute and late radiation side effects. Limb preservation with good functional outcome was achieved in the majority of patients. Trial registration NCT01382030, EudraCT 2004-002501-72, 17.06.2011

    ABSTRACT: The aim of the present study is to assess the disease profile, outcome and prognostic factors in patients treated with surgery combined with radiotherapy (RT), with or without chemotherapy (CXT), for soft-tissue sarcoma (STS) in a multidisciplinary setting. One hundred and sixty-four patients with STS treated between 1980 and 2010 at the Centre Hospitalier Universitaire Vaudois were enrolled in this retrospective study. Seventy-six percent of patients underwent postoperative RT with (24%), or without (52%) CXT, 15% preoperative RT with (5%), or without (10%) CXT, surgery alone (7%), or RT alone (2%) with or without CXT. The median follow-up was 60 months (range 6-292). Local failure was observed in 18%, and distant failure in 21% of the patients. Overall survival (OS), diseasefree survival (DFS), local control (LC) and distant metastases-free survival (DMFS) were 88%, 68%, 83%, and 79% at 5 years, and 80%, 56%, 76%, and 69% at 10 years, respectively. In univariate analyses, favorable prognostic factors for OS, DFS, and DMFS were tumor size 6 cm or less, World Health Organization (WHO)/Zubrod score 0, and stage 2 or less. Age and superficial tumors were favorable only for OS and DMFS respectively. STS involving the extremities had a better outcome regarding DFS and LC. Histological grade 2 or less was favorable for DFS, DMFS, and LC. Radical surgery was associated with better LC and DMFS. RT dose more than 60 Gy was favorable for OS, DFS, and LC. In multivariate analyses, independent factors were age for OS; tumor size for OS, DFS and DMFS; WHO/Zubrod score for OS, DFS and LC; hemoglobin level for DFS; site for DFS and LC; tumor depth for DMFS; histological grade for DFS and LC; surgical procedure for LC and DMFS; and RT dose for OS. This study confirms that in a multidisciplinary setting, STS have a fairly good prognosis. A number of prognostic and predictive factors, including the role of surgery combined with RT, were identified. Regarding RT, a dose of more than 60 Gy was associated with a better outcome, at the price of a higher toxicity. We could not demonstrate a superiority of preoperative RT over postoperative RT.
