Abstract

Introduction: Ewing sarcoma (ES)/PNET is an aggressive malignant tumor with small round cell morphology affecting mainly children and adolescents. The aim of this study was to study the clinicopathological parameters and immunohistochemical panel of skeletal and extraskeletal ES and to correlate with overall survival.
Case Report: Medical files of 70 patients with ES treated at our center between 2009 and 2015 were retrospectively evaluated. The clinico pathological parameters were extracted and statistically correlated with overall survival(OS). Among 70cases of ES ,41 cases were males and 29 cases were females. Most common age group was 10–20 years. Skeletal involvement was seen in 45 cases(64.2%) and 25cases (35.8%) were extraskeletal. The most common skeletal sites of involvement was lower extremity involving  the Femur (24%) and the most common extraskeletal site involved in our study was sinonasal area(5.7%), followed by chestwall, thigh, orbital, calf, gluteal, kidney, and vulva. Two cases showed involvement of the central nervous system(CNS) involving pineal gland and the ventricle. Two cases showed multiple sites of involvement both including chest wall and thigh. Twenty-nine cases(41.4%) showed metastasized disease. The most common site of metastasis was lung followed by bone and brain. Recurrence was seen in 14 cases(20%). Overall 5-year survival was 24%. There was statistically significant correlation found between tumor size (≥8cm) and 5year survival. Furthermore, significant correlation was found between metastasis and 5-year survival.
Conclusion: ES is an aggressive tumor involving skeletal and extraskeletal sites affecting commonly young people, with a poor prognosis for patients with maximum diameter ≥8cm. Metastasisis common in ES and is also a poor prognostic factor.
Keywords: Ewing’sarcoma, skeletal, extraskeletal, survival, metastasis.

Abstract

Objective: The aim of this study is to compare the diagnostic efficiency of bone scintigraphy, fluorodeoxyglucose (FDG), and sodium fluoride (NaF) positron emission tomography/computed tomography (PET/CT) in the evaluation of bone metastasis of the several malignant tumors.
Materials and Methods: A total of Thirteen13 patients (9nine Ffemales and, 4four Mmales; mean 62,.3 ± 7,.1 years) with diagnosis of different malignant tumors were included in the study. The comparison of bone scintigraphy, FDG, and NaF PET/CT results were was performed retrospectively.
Results: The NaF PET/CT demonstrated all the metastatic patients in this series; however, FDG PET/CT missed 7/13 and bone scintigrapyhy 1/13 of the patients with bone metastasis. NaF PET/CT showed significantly higher number of metastatic lesions in all the patients.
Conclusion: The lesion- based analysis showed that NaF PET/CT is significantly superior to FDG PET/CT and bone scintigraphy and patient- based analysis lower detection rate for the FDG PET/CT.
Keywords: Bone, scintigraphy, metastasis, sodium fluorideNaF, fluorodeoxyglucosefdg.
