ABSTRACT
Our study was carried out to define the efficacy of treatment with sequential chemotherapy lines in patients with epithelioid sarcoma (ES) at referral centres for sarcoma. From 1998 to 2023, 22 patients with ES were treated with chemotherapy and included in the analysis. The median age at the start of palliative treatment was 35 (20-68). The median follow-up was 22.1 months. In the first line, 13 patients (59%) received anthracycline-based chemotherapy and 6 (27%) high-dose ifosfamide. One patient (4.5%) achieved PR, 15 (68%) SD, and 6 (32%) PD as the best response. The median progression-free survival (PFS) in the first line was 6.4 months (95% CI 3.02-12.9), but 9.7 months (95% CI 4.37-NR) for chemotherapy based on anthracycline, indicating a more favourable PFS (p = 0.027). Twenty (90%) patients received second-line treatment, and eleven received third-line chemotherapy. The median OS from the start of first-line palliative chemotherapy was 22.1 months (95% CI 10.5-41.4) and 14.7 months from the beginning of the second line. Perioperatively, patients pretreated with anthracycline had a median PFS of 2.9 months in the M1 setting. Second-line long-time responses were achieved with pazopanib or vincristine with actinomycin D. Despite chemoresistance, an advantage associated with anthracycline-based chemotherapy was confirmed in the ES cohort. Poor responses underscore the need for further research on targeted therapies for ES. Second-line chemotherapy or clinical trials should be offered to all eligible patients.
