Abstract
Background: Desmoplastic small round-cell tumor has been identified as a neoplasm with multidirectional immunohistochemical, and molecular features of this tumor sets it apart as a pathologic entity. The optimal treatment remains to be determined.
Methods: Five adult patients were treated according to a uniform first-line chemotherapy program including cisplatin, etoposide, cyclophosphamide, and either doxorubicin or epirubicin. Chemotherapy was delivered after initial surgery in the four patients with intra-abdominal presentation, and at relapse in the fifth patient who had a paratesticular primary tumor.
Results: All 4 patients with intra-abdominal disease experienced stability lasting from 4 to 9 months. Only one objective persistent complete response was observed; this was in the patient with a paratesticular primary. No salvage treatment was active in the other four patients who died of progressive disease.
Conclusions: Our experience to a certain degree of chemosensitivity for desmoplastic small round-cell tumors. Despite aggressive treatments, survival rates remain disappointing. Other therapeutic modalities are needed to improve these results.
