Can cure be achieved in patients with head and neck carcinomas? The problem of second neoplasm.
The improvement in locoregional control of head and neck carcinomas over the last few decades does not appear to modify the final survival of these patients, mainly due to the appearance of distant metastases and second neoplasms. This article reviews the topic of second neoplasm in patients with an index tumor in the head and neck, making a special point of the incidence and epidemiology of second neoplasms, the influence on prognosis, etiopathogenic theories and the possibility of prevention.
