Long-term Ovarian Fertility in Patients Treated for Lymphoma.

Study Overview
=================
Brief Summary
-----------------
This is an observational, single-center, longitudinal cohort study. In order to evaluate the gonadotoxicity of chemotherapy, an AMH monitoring was initiated in 2006 in our fertility observatory in young patients with lymphoma before, during and after chemotherapy. This study is part of the project She will get better and then want a child and is supported by the ARS hauts de France (n° DOS/SDES/AR/FIR/2019/282). Our first study published in 2010 shows that AMH decreases sharply during chemotherapy, regardless of the chemotherapy protocol. At the end of chemotherapy, AMH recovery profiles differ according to the protocol received. This follow-up is therefore essential in order to adapt our practices and our preservation strategies, particularly to the type of chemotherapy. Patients are primarily concerned about their chances of subsequent pregnancy, and there is little evidence in the literature about the impact of chemotherapy on ovarian reserve and long-term fertility. The fisrt objective of our study is to evaluate, at distance from chemotherapy, the evolution of ovarian function in patients treated for lymphoma by evaluating follicular reserve parameters (AMH and antral follicle count) at 5 and 10 years after the end of chemotherapy compared with the initial workup performed before chemotherapy and the workup performed at 12 months after the end of chemotherapy.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Follicular reserve parameters (AMH and antral follicle count) | Follicular reserve parameters (AMH and antral follicle count) at 5 and 10 years after the end of chemotherapy compared with the initial workup performed before chemotherapy and the workup performed at 12 months after the end of chemotherapy | at the end of chemotherapy | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cumulative incidence of pregnancy at 5 years and 10 years from the end of treatment defined by the achievement of at least one spontaneous or induced pregnancy. |  | at 5 and 10 years after the end of chemotherapy. | 
| Pregnancy rate obtained by ART (with or without gamete reuse) | defined by the ratio between the number of clinical pregnancies and the number of ART attempts performed (with or without gamete reuse or frozen ovarian tissue). | at 5 and 10 years after the end of chemotherapy. | 
| Rate of miscarriages, ectopic pregnancies, and live births (single, multiple) | defined by the ratio of the number of miscarriages, ectopic pregnancies, and live births to the number of pregnancies obtained by ART (with or without reuse of gametes or frozen ovarian tissue). | at 5 and 10 years after the end of chemotherapy. |

| Quality of Life (FACT-G7) |  | at 5 and 10 years after the end of chemotherapy. | 
| Life Satisfaction (SWLS) scales |  | at 5 and 10 years after the end of chemotherapy. |
