"Until two-three decades ago, multiple malignant tumours (MMT) were considered a clinical curiosity. Sporadic reports, such as single cases descriptions, could be found in literature. Unfortunately, multiple malignant tumours (MMT) are nowadays increasing, paradoxically because of the better prognoses for several neoplasms: in fact, in patients surviving after a first tumoral disease, other tumors can arise in different districts. It is therefore very important to understand the characteristics of these associations; first of all, a clear definition and classification, based on chronological, clinical and on some other parameters should be made available; furthermore, some aspects concerning etiology and about genetic, iatrogenic, environmental factors should be investigated, in order to ameliorate early diagnosis and therapeutic protocols. Scope of this volume is to describe the state of the art about MMT."
