BACKGROUND: This study aimed to explore the potential impact of stage, grade, and hormone receptor profile on ovarian stimulation response and fertility preservation outcomes.
METHODS: This retrospective cohort study evaluated data from breast cancer patients who underwent fertility preservation at a tertiary medical center between 2014 and 2022. The outcomes of women with low-stage cancer (stages I and II) were compared with those of women with high-stage disease (stages III and IV or lymph node metastasis). Similarly, we compared those with low-grade (grades 1 and 2) and high-grade (grade 3) malignancies. In addition, we compared different hormone statuses of breast cancer (1) estrogen receptor (ER) positive vs. ER-negative and (2) triple-negative breast cancer (TNBC) vs. non-TNBC. The primary outcome measured was the number of mature oocytes, while the secondary outcomes included the numbers of total oocytes retrieved, peak estradiol levels, and subsequent fertility preservation outcomes.
RESULTS: A total of 47 patients were included. Patients with high-grade tumors had a comparable number of mature oocytes (8 vs. 10, p = 0.08) compared to patients with low grade cancers. The stage-based analysis revealed a similar number of mature oocytes (8 vs. 10, p = 0.33) between high/low stage patients. In the hormone receptor-based analysis, no differences were seen in mature oocytes collected between the ER-positive/ER-negative group (9 vs. 9, p = 0.87) and the TNBC/non-TNBC group (11 vs. 9, p = 0.13). The utilization rate was 27.6% (13/47).
CONCLUSION: Our study showed similar ovarian stimulation response and fertility preservation outcomes among breast cancer patients with different prognostic factors.
