Cancer

Tumors originate from the alteration of cells that multiply and spread escaping the mechanisms that maintain the balance of the different tissues. There are numerous types of tumors that can affect virtually any organ and are generally classified as benign or malignant depending on its ability to invade surrounding tissues and more distant organs. The term neoplasms include solid organ tumors and those of blood cells such as lymphomas and leukemias. Some tumors are exclusive or more frequent in the male or female gender and differences in genders can also be observed in the response to therapies.

Despite the great successes obtained in the last decades with prevention, early diagnostics and therapy measures, malignant tumors continue to be among the leading causes of death and deterioration of life quality; and also due to longer average life spans, in many cases, cancer incidence increases with age. For some neoplasms, mortality has decreased markedly; for others, despite the great commitment of research, the need remains to find new, more effective and specific therapies.

Cancer therapy is essentially based on surgery, especially in localized forms, radiotherapy and drugs. By identifying molecular alterations (tumor genetics) or targets that are present exclusively, or prevalently, on cancer cells, drugs have been developed in recent years aimed at selectively targeting cancer cells. Prevention is fundamental, and by studying the epidemiology of tumors it is possible to identify environmental or lifestyle-related risk factors that can be corrected to reduce the risk of developing cancer.

The Istituto Superiore di Sanità (ISS, the National Institute of Health in Italy) carries out research in the field of oncology, hematology and genetic diseases, and with a translational orientation.



Back Sovrappeso, dimagrimento, danno e riparazione del danno al DNA

 

Che relazione c’è tra eccesso ponderale e danno del DNA? Cosa succede ai meccanismi normalmente deputati alla riparazione del danno al DNA quando c’è una situazione di sovrappeso o di obesità? E cosa cambia dopo un calo ponderale? Il Registro Nazionale Gemelli, in collaborazione con il dipartimento Ambiente e Salute dell’Istituto superiore di sanità e con il dipartimento di Medicina dei Sistemi dell’Università di Roma Tor Vergata, sta studiando 16 coppie di gemelli monozigoti composte da un gemello normopeso e l’altro in sovrappeso. Si stanno indagando il danno al DNA e le proteine deputate alla sua riparazione, i profili metabolico, lipidico e infiammatorio, lo stress ossidativo e il microbioma prima e dopo il dimagramento del gemello sovrappeso a seguito di una dieta ipocalorica di alcuni mesi. Studiare due gemelli geneticamente identici ci permette di analizzare gli effetti della differenza di peso, indipendentemente dall'influenza del patrimonio genetico ereditario. Accanto alle coppie di gemelli, stiamo studiando anche 36 pazienti obesi – non gemelli - che si sottopongono a chirurgia bariatrica per perdere peso.
