About

Pelvic chemoradiotherapy (CRT) is an effective treatment for Locally Advanced Cervical Cancer (LACC). However, CRT induces premature ovarian failure ceasing the production of ovarian hormones. This may lead to severe consequences to the patient's life quality, sexuality and overall healthy. An acceptable treatment to minimize the adverse effects caused by the lack of ovarian hormones is hormonal replacement but less than 40% of the patients younger than 50 years have access to this treatment. A second alternative treatment is ovarian transposing which is a surgical technique with variable success rate depending on how far the ovaries are from the radiotherapy field. A third, more promising, alternative is involves using autologous ovarian tissue as a graft in tissues far from the radiotherapy field. This treatment has the potential of maintaining the natural ovarian hormones production at a lower-cost and requiring a simpler procedure. The primary objective of this randomized phase 1-2 clinical trial is to validate the feasibility of ovarian tissue engraft into fatty tissue and its endocrine functionality.

Description:
10 patients: Pelvic Chemoradiotherapy
Ovarian Graft
Experimental group
Description:
10 patients: Before the beginning of pelvic radiotherapy, one of the ovaries will be removed by laparoscopy. Ovary slices of 1-2 mm will be prepared in sterile environment and engrafted in the fatty tissue of inner tight. One representative fragment will undergo histologic evaluation. These procedures will be done in the same surgical time.

Procedure: Ovarian graft
