A commentary on the narrative review of primary Ewing’s sarcoma of the orofacial region

I would like to congratulate Indumathi et al.[1] for their interesting publication titled, "Primary Ewing's sarcoma of the orofacial region: A narrative review," published in the Cancer Research, Statistics and Treatment journal. This review is clinically relevant for the readers as it serve as an update for clinicians on various clinical aspects of Ewing's sarcoma of the maxillofacial region. However, I have a few queries and would appreciate it if the authors could provide clarifications on the same. The selection of the subject heading terms for literature search could have been more refined, the current terms could have resulted in missing out case reports. For instance, a recent case report on Ewing's sarcoma of the mandibular condyle by Kudva et al.[2] was not included in this review. Furthermore, since narrative reviews are a vital source of literature based on a topic, a well-performed search strategy is crucial. The authors have detailed the methods employed for the search used in Figure 1; kindly clarify if manual searching of articles was also done.[1] The authors could have also discussed how many authors performed the two-step literature screening, as stated in the methodology. Was there any specific reason as to why the timeline for search was from 2011–2022 only? Imaging plays a major role in the assessment of neoplasms, and hence, the authors could have been more specific in stating the type of radiographic findings (panoramic radiograph/paranasal sinus view, etc.) rather than stating only computed tomography and magnetic resonance imaging, since Ewing's sarcoma may also manifest atypically as common odontogenic complaints in a few cases where conventional radiography has a role in the initial diagnostic process. Since a narrative review is a consolidation of individual reports in a systematic manner, adhering to references and citations is important.[3] The results and discussion sections were lacking in this aspect in certain areas. Appropriate citations in the suitable sections would enhance the clarity of the content to the readers. Financial support and sponsorship Nil. Conflicts of interest There are no conflicts of interest.
