Preface

摘要

An increasing use of minimally invasive diagnostic procedures together with continuously growing ancillary techniques applied to cytological specimens brought widespread acceptance of using fine-needle aspiration cytology (FNAC) in the diagnosis of soft tissue and bone lesions. While cytological examinations have been used in many centers to follow up on previously treated sarcomas or to confirm soft tissue and bone metastases, in the last decade the primary diagnosis of soft tissue and bone tumors has emerged as an important new target for FNAC. As the first-line approach, cytologic examination most often provides diagnostic information allowing the initiation of treatment or guidance of the continued diagnostic investigation.
