This pilot/exploratory study will be configured as a non-retro-prospective study interventional on endometrial tissue samples taken from surgically treated patients at the Regina Elena National Cancer Institute, IRE - IFO and stored at the Biobank of same Institute (BBIRE) (cohort 1) and on samples of decidualized endometrium and trophoblast from patients with ongoing spontaneous abortion treated surgically at the UOC of Gynecology ed Obstetrics of the Federico II University Polyclinic of Naples (cohort 2)

Court 1: tissue samples (healthy and tumor taken from the same patient) collected at the Institute's Biobank (starting from 2017) (retro-prospective); Court 2: tissue samples (decidualized endometrium and trophoblast taken from it patient) which will be collected at the Gynecology and Obstetrics Unit of the Polyclinic Federico II University of Naples (prospective) and transfer to the Regina National Cancer Institute Elena, IRE-IFO.
The following data will be collected for each patient:
Age, ethnicity, parity, luxury habits, level of education, marital status, height, weight, index of body mass
Data on previous clinical history, previous gynecological-obstetric pathologies and any treatments, current comorbidities and medical therapies
For Cohort1 patients only:
Data relating to the neoplastic pathology: histotype, grading, FIGO stage
Data on oncological follow-up: any intra- or post-operative complications, any therapies adjuvants, type and data of any recurrence/metastasis, type of treatment if any recurrence, date and manner of death.
