Abstract
Introduction
Breast cancer is the most common malignancy in women of reproductive age and chemotherapy protocols impair fertility, frequently necessitating fertility preservation (FP) referral. Embryo, oocyte, or ovarian tissue cryopreservation are established FP modalities in women with breast cancer but there are few data on their uptake over time. In this study our aim was to determine the regional time trends and utility differences for fertility preservation methods of reproductive tissue cryopreservation.
Methods
This multicenter study included 1623 women diagnosed with breast cancer from 7 tertiary centers in 6 countries (Brazil, Italy, Scotland, South Korea, Turkey, USA). Participant centers provided the details of FP cryopreservation approaches broken down annually from 2012 to 2021. Women with newly diagnosed breast cancer, aged 18-45 years who were referred for FP at participating centers and had normal ovarian function at the time were included.
Results
We found a mean increase of 7% per year (P = .002, adjusting for centers) in the number of women referred for FP. Of those who were referred (n = 1623), a mean 38.7% underwent FP (n = 629), with a range of 12% in South Korea) to 95% in Brazil. The number of women undergoing ovarian stimulation for FP continually increased until 2021, with oocyte cryopreservation being the most common procedure throughout the study period (P = .014 for time trend). The proportion of random start ovarian stimulation cycles increased each year from 58.3% in 2012 to 86.8% in 2021, (P = .005 for time trend, and P = .04 for 2012 vs. 2021).
Conclusions
The utility of FP has steadily increased for young women with breast cancer over the last decade, although regional differences significantly influence FP practices. The findings of our study could have value for policy making in FP care for young women with breast cancer at the local, regional, or global level.
期刊介绍:
Clinical Breast Cancer is a peer-reviewed bimonthly journal that publishes original articles describing various aspects of clinical and translational research of breast cancer. Clinical Breast Cancer is devoted to articles on detection, diagnosis, prevention, and treatment of breast cancer. The main emphasis is on recent scientific developments in all areas related to breast cancer. Specific areas of interest include clinical research reports from various therapeutic modalities, cancer genetics, drug sensitivity and resistance, novel imaging, tumor genomics, biomarkers, and chemoprevention strategies.
