Cancer in pregnancy: Proposal of an italian multicenter study. gynecologic oncology group of the italian society of gynecology and obstetrics (sigo)

A pregnancy related cancer is defined as a neoplasm diagnosed in a woman during gestation or within 12 months following childbirth or abortion. Breast, thyroidal, melanoma, cervical and hematological malignancies are those most commonly diagnosed during pregnancy, with a reported incidence considered lower than those estimated of 1 case on 1000 pregnancies. The clinical complexity is generated by the co-presence of mother and fetus, and the consequent conflict represented by the need to identify a therapeutic strategy that is effective for the maternal prognosis and, at the same time, safeguards the fetal well-being. Moreover, the counseling, diagnosis, staging and management of these cases are further complicated because most of the scientific literature consists in case reports or small retrospective studies and lacks in guidelines and prospective clinical trials. On that basis, the Study Group on Cancer in Pregnancy (members of S.I.G.O.-Italian Society of Gynecology and Obstetrics) presents the TIGRE Trial, an Italian multicenter observational study aimed at establishing a shared database for the collection of epidemiological and clinical data of the patients affected by pregnancy related cancer in Italy, with the final objective to improve the outcome of a mother and a child involved in a such pathology.
