Feasibility study for interspecialistic collaboration in active research of urothelial neoplasms of professional origin.

Introduction: In Italy only a small fraction of cancer is reported to the supervisory body and recognised as professional by the insurance institution. Among the causes of this sub-notification, especially for lowgrade etiologic fractional cancers such as bladder cancers are the lack of knowledge of carcinogenicity in the occupational field and the consequent incomplete medical history collections.

Objectives: Diagnosis of occupational bladder neoplasms and activation of systematic surveillance of tumors of professional origin through an "active research" program.

Methods: From July 2010 to July 2017, all patients diagnosed with Bladder Cancer in the departments of Urology of Area Vasta 3 ASUR Marche underwent a first interview and a further anamnestic study in selected cases.When an occupational exposure was recognised, more information for preventive, social security and criminal justice has been acquired.

Results: The study highlighted 18 cases of bladder tumors due to occupational exposure to aromatic amines and polycyclic aromatic hydrocarbons, which are the most important risk factor for BC after tobacco smoking.

Conclusions: Our study confirmed that active research is an useful tool both for the activation of epidemiological surveillance and for the regional registration of professional tumors. In addition active research of occupational exposure allow obtaining information that can be used for preventive purposes, for criminal justice and for the initiation of medico-legal actions and improvement of working conditions aimed at guaranteeing workers' rights.
