Efficiency of Gonadotropin-releasing Hormone (GnRH) Agonist in Preventing Chemotherapy Induced Ovarian Failure

2014-07-23 21:08:28 | BioPortfolio

Summary

Chemotherapy drugs like alkylating agents are frequently used in various combined regimens to treat neoplastic and benign diseases. These drugs are definitely associated with premature ovarian failure (POF), resulting in an important decrease of the long-term quality of life and an increase of morbidity. A recent study showed that the patients treated by alkylating agents had a 4.52 fold higher risk to lose their ovarian function compared with those who were treated by other agents. The rate of POF after treatment ranged from 40 to 80%, according to the age of the patients and the total doses administered.

Young women who experience POF have to face with the prospects of infertility and to consider years of hormonal replacement therapy. The possibility of minimizing gonadal damage by administering of protective therapy during chemotherapy represents an attractive option for these patients.

The aim of this study is to evaluate the protective effect on the ovarian function of the gonadotropin-releasing hormone agonist (GnRha) administered concomitantly to alkylating agents. Preliminary data in the literature on animals (rat and monkeys) are promising. Data in human are, however, highly controversial.

Medical and Biotech [MESH] Definitions

An enzyme that catalyzes the conversion of acetate esters and water to alcohols and acetate. EC 3.1.1.6.

Megestrol acetate is a progestogen with actions and uses similar to those of the progestogens in general. It also has anti-androgenic properties. It is given by mouth in the palliative treatment or as an adjunct to other therapy in endometrial carcinoma and in breast cancer. Megestrol acetate has been approved to treat anorexia and cachexia.
