Colorectal cancer (CRC) incidence is rising among reproductive-age women, yet chemotherapy frequently compromises ovarian reserve, impairing fertility. Ovarian reserve assessment traditionally relies on serum follicle-stimulating hormone (FSH) and anti-Müllerian hormone (AMH), while uterine artery Doppler parameters - pulsatility index (PI), resistance index (RI), and peak systolic velocity (PSV) - reflect ovarian perfusion. However, their combined correlation with post-chemotherapy ovarian reserve remains underexplored. We hypothesize that integrating these parameters will enhance predictive accuracy for diminished ovarian reserve, informing fertility preservation strategies.
To investigate correlations of uterine artery blood flow, FSH, and AMH with ovarian reserve post-chemotherapy in reproductive-aged CRC patients.
This study included 110 reproductive-aged women with CRC who received chemotherapy from March 2021 to September 2024. Based on criteria assessed three months post-chemotherapy, they were divided into diminished (n = 50) and normal (n = 60) ovarian reserve groups. Uterine artery PI, RI, PSV, serum FSH, and AMH were compared. Correlations and predictive efficacy were analyzed using Pearson correlation and receiver operating characteristic (ROC) curves.
The diminished ovarian reserve group exhibited significantly higher uterine artery PI, RI, and serum FSH levels, but lower PSV and serum AMH levels than the normal ovarian reserve group (P < 0.05). Correlation analysis showed PI, RI, and FSH were positively correlated with ovarian reserve decline (r = 0.395, 0.420, 0.378; P < 0.05), whereas PSV and AMH were negatively correlated (r = -0.506, -0.614; P < 0.05). ROC curve analysis revealed AMH had the best predictive value among single markers [area under the curve (AUC) = 0.895], with AUCs of 0.726, 0.733, 0.791, and 0.723 for PI, RI, PSV, and FSH, respectively. Combined detection of all five indicators increased the AUC to 0.950, with 94% sensitivity and 90% specificity, significantly outperforming any single indicator (P < 0.05).
In post-chemotherapy reproductive-age CRC patients, elevated PI, RI, FSH and reduced PSV, AMH correlate with diminished ovarian reserve. Combined testing at three months aids risk identification and fertility preservation.
Core Tip: Combined assessment of uterine artery Doppler parameters [pulsatility index (PI), resistance index (RI), and peak systolic velocity (PSV)] with serum follicle-stimulating hormone (FSH) and anti-Müllerian hormone (AMH) levels demonstrates superior predictive value for diminished ovarian reserve in reproductive-aged colorectal cancer patients after chemotherapy. The combined detection achieved an area under the curve of 0.950, significantly outperforming any single indicator, with PI, RI, and FSH positively correlated, while PSV and AMH negatively correlated with ovarian reserve decline. This multimodal approach provides a non-invasive, comprehensive strategy for early identification of che
