Fertility Preservation in Young Women with Breast Cancer: Impact on Treatment and Outcomes

A Retrospective Study of Fertility Counseling and Preservation Rates for Women of Reproductive Age With Breast Care After Integrating a Fertility Specialist Into a Multidisciplinary Tumor Board

INTRODUCTION

Many breast centers have adopted multidisciplinary tumor boards to discuss and develop treatment plans for patients diagnosed with breast cancer. This study aims to determine whether adding a fertility specialist to tumor board will improve fertility counseling and utilization in breast cancer patients METHODS: A retrospective study of reproductive age patients diagnosed with breast cancer between January 1, 2012, and January 31, 2020, before and after integrating a designated fertility specialist into a comprehensive multidisciplinary care (cMDC) tumor board. Rates of fertility counseling and preservation were assessed for patients treated before (pre-cMDC) and after (post-cMDC) tumor board enhancement. Associations of race/ethnicity, age, chemotherapy, hormone receptor status, insurance type, parity, stage, site of treatment, and home county with fertility care rates were assessed in the post-cMDC group.

RESULTS

Of 306 patients diagnosed with breast cancer, 117 (38%) were in the pre-cMDC and 189 (62%) were in the post-cMDC tumor board group. Significantly more patients in the post-cMDC tumor board group were offered fertility counseling than patients in the pre-cMDC tumor board group (23.3% (44) vs. 0.9% (1); P < .001). However, rate of fertility preservation did not differ significantly between groups.

CONCLUSION

Integrating a fertility specialist within a cMDC tumor board may help improve rates of fertility counseling among breast cancer patients but may not improve preservation rates.

Impact of Systemic Therapy on Fertility in Women with Early-Stage Breast Cancer

Purpose of Review

Fertility concerns are common among young women diagnosed with breast cancer, as systemic therapy increases the risk of premature ovarian insufficiency and delays family planning. Here, we review the impact of systemic therapies, including chemotherapy, endocrine therapy, HER-2 directed therapy, PARP inhibitors, and immunotherapy, on ovarian reserve.

Recent Findings

With an improved understanding of disease biology, fewer women are treated with gonadotoxic chemotherapy. There are limited data on the fertility impact of novel targeted treatments and immunotherapy, though preclinical and preliminary studies suggest an impact on fertility is possible. Notably, a recent study investigated the outcomes in women who interrupted adjuvant endocrine therapy to attempt pregnancy.

Summary

Further research is needed to characterize the fertility impact of novel therapies in breast cancer. Individualized fertility counseling should be offered to all women to discuss the possible impact of therapy on ovarian reserve and options for fertility preservation and timing of pregnancy.

Disparities in fertility preservation among patients diagnosed with female breast cancer

PURPOSE

To investigate the association of specific patient factors with disparities in fertility preservation counseling and utilization of fertility preservation among patients ≤ 40 years old diagnosed with female breast cancer.

METHODS

A retrospective chart review was conducted investigating patients diagnosed with breast cancer between January 2012 and December 2020 in a multi-site health system. Rates of fertility counseling and utilization of preservation services were compared based on age, race/ethnicity, parity, insurance type, and treatment site.

RESULTS

Of the 6,783 patients diagnosed with female breast cancer, 306 (4.5%) were ≤ 40 years old at the time of diagnosis. There was no significant difference between Black or African American and White patients in rates of fertility counseling (12.1% vs 17.4%; p = 0.285) or pursuit of fertility preservation (3.3% vs 4.2%; p = 0.508), nor was a difference observed when compared by insurance type. However, younger patients (< 30 years of age), patients with 1 or no children, and patients treated in the more affluent county were more likely to undergo counseling and pursue fertility preservation than their matched counterparts.

CONCLUSION

Age, parity, and location of breast cancer care may impact rates of fertility counseling and preservation among reproductive age women diagnosed with breast cancer. Thus, further attention to age discrimination, a patient's desire for future fertility, need for standardization in fertility preservation counseling, and perhaps implementation of comprehensive fertility coverage mandates across all states could help to improve gaps in fertility counseling and fertility preservation.

Clinical Features and Outcomes of Triple-Negative Breast Cancer Among Latin American Adolescents and Young Adults Compared to Middle-Aged and Elder Females: A Cohort Analysis Over 15 Years

Purpose: Outcomes of females with triple-negative breast cancer (TNBC) are rarely explored in adolescents and young adults (AYAs). We compared clinical and survival outcomes of Latin American AYAs (≤39 years) with middle-aged (40-59 years) and older (≥60 years) females with TNBC by cancer stage. Methods: We performed a single-center retrospective cohort study among treated females with cancer stages I-III diagnosed from 2000 to 2014 in Peru. We evaluated overall survival (OS) and event-free survival (EFS). Time-to-event methods were used for analyses. Results: Of 1582 females with TNBC, 350 (22%) were AYAs, 887 (56%) were middle-aged, and 345 (22%) were older women. Tumor size >5 cm, histological grade III, and brain metastasis were more common features in AYAs. AYAs were treated more frequently with neoadjuvant chemotherapy. With a median follow-up of 102 months, the 5-year OS/EFS for AYAs was 55%/53%, similar to middle-aged (54%/49%) and older females (56%/51%). AYAs were not at higher risk for decreased OS or EFS in the multivariable Cox analysis. Our findings remained consistent by cancer stage. Conclusion: Although Latin American AYAs with TNBC have more aggressive clinical features at diagnosis, survival outcomes were comparable with middle-aged and older women with TNBC, suggesting that age is not a risk factor for worse survival outcomes if treatment is given according to cancer stage. Our findings should be interpreted with caution given the lack of information on certain covariates such as comorbidities. Strategies for early detection in primary care and prompt referral for treatment initiation should be developed.

Disparity in Breast Cancer Care: Current State of Access to Screening, Genetic Testing, Oncofertility, and Reconstruction

Breast cancer is the most common cancer diagnosed in women, accounting for an estimated 30% of all new cancer diagnoses in women in 2022. Advances in breast cancer treatment have reduced the mortality rate over the past 25 years by up to 34% but not all groups have benefitted equally from these improvements. These disparities span the continuum of care from screening to the receipt of guideline-concordant therapy and survivorship. At the 2022 American College of Surgeons Clinical Congress, a panel session was dedicated to educating and discussing methods of addressing these disparities in a coordinated manner. While there are multilevel solutions to address these disparities, this article focuses on screening, genetic testing, reconstruction, and oncofertility.
