“…The 5‐year survival rate in previous literatures ranged from 10% to 30%, and was 8% in another study (13 RISHN patients, single institution) 28,29 . Significantly worse survival times have been reported for patients with RIS than in those with sporadic (de novo) undifferentiated pleomorphic sarcoma/malignant fibrous histiocytoma 30–32 . High‐grade tumors, older age (>60 years), gross positive resection margins, and tumor size >5 cm were predictors of poor sarcoma‐specific survival 33,34 .…”

Radiation‐induced sarcoma of head and neck: Clinical characteristics and molecular signatures

et al. 2022

Background Radiation‐induced sarcoma of the head and neck (RISHN) is a rare yet devastating potential complication of radiotherapy treatment. We aimed to evaluate the clinicopathological characteristics and molecular signatures of RISHN in patients who underwent radiotherapy for head and neck cancer (HNC) to identify high‐risk patients and enable earlier cancer detection. Methods This study retrospectively evaluated 24 sarcoma patients who received radiotherapy for HNC between 1994 and 2019. Patients were divided into two groups based on RISHN latency period. Patient demographics, initial tumor staging, risk factors, and survival between groups were analyzed, and whole‐exome sequencing (WES) of selected samples was performed. Results The median age at diagnosis of RISHN was 54 years, and the male‐to‐female ratio was 2:1. The latency period ranged from 0.8 to 64.4 years (median 6.5 years), with a median survival of 21.5 months. Primary cancer in the oral cavity, treatment with alkylating agents, alcohol consumption, betel nut chewing, and smoking were identified as risk factors for short (<5 years) latency periods. The majority of RISHN cases occurred in the oral cavity (58.3%). WES analysis showed that tumor necrosis factor and cell cycle checkpoint pathways were differentially involved in both patient groups. Conclusions Although case numbers were small, our cohort represents the largest case series of RISHN from a single institution to date. Clinicians must be aware of factors affecting RISHN development and latency, and risk factor identification may lead to earlier detection and prevention in the future.

“…An important finding of this systematic review concerns the age at diagnosis. Sarcomas in the head and neck region are commonly diagnosed in middle‐aged adults (Moreira et al, 2020; Yanzon et al, 2021). Alishahi et al (2015), for example, observed in their retrospective study that individuals with sarcomas had a mean age of 41 years.…”

Ewing's sarcoma of the head and neck: A systematic review

et al. 2023

View full text Add to dashboard Cite

ObjectiveThe aim of the present study was to conduct a systematic review of head and neck Ewing sarcoma (ES) concerning patients' demographic and clinical features, histopathological findings, treatment, follow‐up, and survival rate.Materials and MethodsAn electronic search was undertaken in four databases. Articles describing case reports or case series were included. Outcomes were evaluated by the Kaplan–Meier method along with Cox regression.ResultsThe search yielded 186 studies describing 227 ES cases. The mean age was 22.7 years, and males were slightly more affected. Interestingly, more than half the cases were diagnosed up to 20 years. The respiratory tract was the most reported site, followed by the jawbones. Clinically, symptomatic swelling or nodules were described, with a mean duration of 4 months. Management involved multimodal treatment regimens. Local recurrence, lymph node and distant metastasis were observed in 10.7%, 12.6%, and 20.3% of cases, respectively. Statistical analysis revealed that older patients with distant metastasis had a lower overall survival rate (p < 0.05).ConclusionThis study provides an overall view of head and neck ES that can assist oral and maxillofacial pathologists with the diagnosis and extend the knowledge of surgeons and oncologists about this condition.
