GDF15 and history of pregnancy-induced nausea as predictors of treatment-induced nausea severity in women following surgery for early-stage breast cancer.
Treatment-induced nausea (TIN) is a persistent and distressing symptom among women undergoing breast cancer therapy, despite adherence to antiemetic guidelines. A history of pregnancy-induced nausea and vomiting (PNV) and genetic variations in GDF15, a stress-responsive cytokine, may contribute to nausea susceptibility. The purpose of this study was to understand the relationship between GDF15 variants, history of PNV, and the prediction of TIN severity across the first 6 months following breast cancer surgery.
A prospective, 6-month longitudinal cohort study enrolled 290 women undergoing surgery for early-stage breast cancer. Nausea severity was assessed using a 0-10 numeric rating scale at multiple time points post-surgery and during adjuvant therapy. Saliva samples were genotyped for GDF15 single nucleotide polymorphisms (SNPs) (rs810804, rs1227731, rs8101249, rs1059369). Group-based trajectory modeling (GBTM) identified nausea severity patterns. Associations between GDF15 SNPs, PNV history, and TIN severity were analyzed using multivariate logistic regression.
Three nausea severity trajectories were identified: extremely low (41%), low (47%), and moderate (12%). A history of PNV significantly predicted higher TIN severity (p < 0.05). Additionally, GDF15 SNPs rs8101249 and rs1227731 were associated with TIN severity trajectories. In the final multivariate model, PNV history and rs1227731 remained significant predictors.
PNV history and GDF15 genetic variants influence TIN severity in women undergoing breast cancer treatment. Identifying at-risk patients may improve symptom management. Future research should explore GDF15-targeted interventions to reduce nausea burden.
