Therapy consisted of alternating cycles of ifosfamide\u2013etoposide, and vincristine, doxorubicin, cyclophosphamide. Vinblastine and celecoxib were concomitantly administered. Surgical, radiotherapeutic, or combination local control therapy was given per institutional preference.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010five eligible patients were enrolled. Ninety percent received at least 75% of planned vinblastine\/celecoxib doses. There was no excess of neurologic, infectious, hemorrhagic, or cardiovascular toxicities. However, 7 of 21 patients who received pulmonary irradiation prior to experiencing pulmonary toxicity did develop grade 2 or greater pulmonary toxicity, including two deaths of apparent radiation pneumonitis. Fourteen of 16 patients with pelvic disease received local irradiation. Hemorrhagic cystitis developed in six patients, five of whom had received pelvic irradiation. The overall 24\u2010month event free survival was 35% (19\u201351%); 71% (26\u201392%) for the seven with isolated pulmonary metastases, 26% (10\u201345%) for all others.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The combination of vinblastine\/celecoxib metronomic therapy with standard ES treatment was feasible according to the protocol definitions. However, excess toxicity in irradiated areas was noted and limits the usefulness of this protocol. The 24\u2010month EFS for those with isolated pulmonary metastases is better than historical controls, although the number of patient number is small, follow up short and we are lacking contemporaneous controls.
