Details and patient eligibility

About

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)

Full description

For the experiments proposed in the project the following will be used:

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.

Clinical data

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.

Enrollment: 30 estimated patients

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Trial design

30 participants in 2 patient groups

Cohort 1: tissue samples (healthy and tumor taken from the same patient)

Description:

Tissue samples (healthy and tumor taken from the same patient) collected at the Institute's Biobank (starting from 2017) (retro-prospective). The data relating to the neoplastic pathology will also be indicated: histotype, grading, FIGO stage. And data on oncological follow-up: any intra or post-operative complications, any adjuvant therapies, type and date of any recurrence/metastasis, type of treatment, any recurrence, date and manner of death

Treatment:

Diagnostic Test: tissue samples (healthy and tumor taken from the same patient) and tissue samples (decidualized endometrium and trophoblast taken from it patient)

Cohort 2: tissue samples (decidualized endometrium and trophoblast taken from it patient)

Description:

The tissue samples (decidualized endometrium and trophoblast taken from it patient) which will be collected from the Gynecology and Obstetrics Unit of the Polyclinic Federico II University of Naples (prospective) and transferred to the Regina National Cancer Institute Elena, IRE-IFO

Treatment:

Diagnostic Test: tissue samples (healthy and tumor taken from the same patient) and tissue samples (decidualized endometrium and trophoblast taken from it patient)
