Sir,
Having read the case report titled 'Rare case of extraskeletal Ewing sarcoma of the sinonasal tract' [1] published recently in the Journal of Cancer Research and Therapeutics (JCRT), we seek a few clarifications from the authors. [1]
The authors have assigned the diagnosis as 'extraskeletal' Ewing sarcoma, which in our opinion is questionable. The preoperative computed tomography (CT) image reveals a large soft tissue mass involving the nasal cavity and the paranasal sinuses, with bony erosion of the walls of the maxillary sinus. Thus, there is a likelihood that the tumor could indeed have originated from the bony structures of the region. [2] Skeletal origin is more likely, given the additional fact that only 4-7% of all Ewing sarcomas happen to be 'extraosseous'. [2],[3],[4]
Regarding the choice of chemotherapy, the authors have mentioned 14 cycles of "vincristine, adriamycin, cyclophosphamide and dexamethasone" in the case report. We assume that the authors intended to mean 'd-actinomycin' instead of dexamethasone. However, we would like to know if the chemotherapy was alternative, with cycles of ifosfamide-etoposide.
In addition, it will be appreciated if the authors can kindly shed some light upon the timing, dose, and technique of delivery of radiotherapy, since that would amount to an interesting description regarding the radiotherapy planning of a rare malignancy in a rare site, with abundance of organs at risk in near proximity.
