mesna and Neuroectodermal-Tumors--Primitive--Peripheral

Peripheral primitive neuroectodermal tumor (PNET) of the cervix uteri is extremely rare. Between 1987 and 2002, there have been eight cases described in the English literature. The treatment policies in these eight cases differed considerably, partly due to the rarity of the disease and to differing time periods of diagnosis and treatment.. At the end of 2002, a 21-year-old woman presented with a PNET of the cervix uteri at our institute, the Erasmus Medical Center. For the appropriate treatment in this case, we reviewed the literature and decided that the treatment should be different from the local surgical treatment followed by additional treatments as most of the earlier reports describe.. In view of the current knowledge of PNET belonging to the family of Ewing's sarcoma, and the improvement of treatment outcome in these tumors due to dose-intensive neo-adjuvant chemotherapy, patients with PNET of the cervix should be treated in accordance to the protocol for bony Ewing's sarcoma with multimodality therapy by means of induction chemotherapy, surgery, and consolidation chemotherapy.

Patients with locally advanced or metastatic/recurrent soft tissue and Ewing's sarcoma (EWS) have few treatment options. The purpose of our phase II study was to assess the feasibility, safety and efficacy of tandem high-dose chemotherapy (HDCT) followed by autologous stem cell transplantation (ASCT) in such patients.. Thirteen patients were enrolled onto this study. The first cycle of HDCT consisted of doxorubicin (150 mg/m(2)) and ifosfamide (14 g/m(2)) mixed with mesna (14 g/m(2)), while the second cycle consisted of melphalan (150 mg/m(2)) and cisplatin (200 mg/m(2)).. Eleven out of 13 patients were able to complete both cycles of HDCT. No treatment-related mortality occurred and grade 3 or 4 toxicity was clinically tolerable. The 5-year progression-free survival (PFS) and overall survival (OS) for all patients was 23% (confidence interval, CI: 0-46%) and 31% (CI: 14-70%), respectively. Out of the four patients still alive, two had EWS and measurable disease at the time of ASCT and achieved a complete remission, remaining progression free 126 and 155 months after ASCT.. Our study demonstrates the feasibility and safety of tandem HDCT in patients with high-risk or metastatic/recurrent sarcoma, with some patients achieving long-term PFS and OS.
