ABSTRACT
PURPOSE: Cervical cancer patients undergoing chemoradiation have high symptom burden. We performed an analysis of prospectively collected patient-reported outcomes(PROs) to determine characteristics predictive of poor treatment experience.
METHODS: Between 2021-2023, we prospectively collected PROs from cervical cancer patients undergoing definitive chemoradiation. EORTC-QLQ-C30 and EORTC-QLQ-CX24 were completed at baseline(BL) and at the end of treatment(EOT). Poor treatment experience was defined as EOT poor health-related quality of life (HRQOL), low physical function, or significant overall symptom burden. Predictive factors analyzed included demographic, clinical, disease-specific factors, and baseline financial toxicity, depression, social function, and emotional function. ROC analysis provided appropriate predictive cut-off values. Univariable(UVA) and multivariable(MVA) linear regression analyses were performed.
RESULTS: Fourty-nine patients completed BL and EOT questionnaires. Median age was 43 (range, 18-85). Most patients (59%) had stage III disease. Baseline financial toxicity ≥66.7, depression ≥66.7, social function ≤50 and emotional function ≤58 on the EORTC linear transformed scale of 0-100 were significant predictors for poor treatment experience (p≤0.04) based on ROC analysis. On MVA poor BL social function was associated with reduced EOT HRQOL (β-9.3,_95%CI_-16.1_to_-2.6,_p<0.008), decreased physical function (β-24.4,_95%CI_-36.3_to_-12.6,_p<0.001), and high symptom burden_(β26.9,_95%CI_17.5_to_36.3,_p<0.001). Earlier disease stage predicted for decreased symptom burden_(β-6.7,_95%CI_-13.1_to_-0.3,_p=0.039). BL financial toxicity was a significant predictor on UVA (p=0.001-0.044) and showed a significant interaction term on MVA (p=0.024-0.041) for all three domains of poor treatment experience. Demographic and treatment-related factors were not predictive.
CONCLUSION: Cervical cancer patients with poor baseline social function or high financial toxicity were at-risk for increased symptom burden and poor HRQOL. Screening for these factors provides an opportunity for early intervention to improve treatment experience.
