Brief Summary:
Osteosarcoma is regarded as most common malignant bone tumor in children and adolescents Approximately 15 to 20 of patients with osteosarcoma present with detectable metastatic disease and the majority of whom 85 have pulmonary lesions as the sole site of metastasis Previous studies have shown that the overall survival rate among patients with localized osteosarcoma without metastatic disease is approximately 60 to 70 whereas survival rate reduces to 10 to 30 in patients with metastatic disease Though lately neoadjuvant and adjuvant chemotherapeutic regimens can decline the mortality rate 30 to 50 of patients still die of pulmonary metastases Number distribution and timing of lung metastases are of prognostic value for survival and hence computed tomography CT thorax imaging still plays a vital role in disease surveillance In the last decade the technology of multidetector CT scanner has enhanced the detection of numerous smaller lung lesions which on one hand can increase the diagnostic sensitivity for lung metastasis however the specificity may be reduced In recent years deep-learning artificial intelligence AI algorithm in a wide variety of imaging examinations is a hot topic Currently an increasing number of Computer-Aided Diagnosis CAD systems based on deep learning technologies aiming for faster screening and correct interpretation of pulmonary nodules have been rapidly developed and introduced into the market So far the researches concentrating on the improving the accuracy of benignmalignant nodule classification have made substantial progress inspired by tremendous advancement of deep learning techniques Consequently the majority of the existing CAD systems can perform pulmonary nodule classification with accuracy of 90 above In clinical practice not only the malignancy determination for pulmonary nodule but also the distinction between primary carcinoma and intrapulmonary metastasis is crucial for patient management However most existing classification of pulmonary nodule applied in CAD system remains to be binary pattern benign Vs malignant in the lack of more thorough nodule classification characterized with splitting of primary and metastatic nodule To the best of our knowledge only a few studies have focuses on the performance of deep learning-based CAD system for identifying metastatic pulmonary nodule till now In this proposed study the investigators sought to determine the accuracy and sensitivity of one computer-aided system based on deep-learning artificial intelligence algorithm for detection and risk stratification of lung nodules in osteogenic sarcoma patients
