Objectives
To assess patient preferences regarding side effects associated with cervical cancer treatment.
Methods/Materials
The visual analog scale (VAS) and modified standard gamble (SG) were used to elicit preferences of women with no evidence of disease following primary treatment for cervical cancer. Higher scores on VAS and SG indicated more favorable ratings for a given health state (HS). HS included: vaginal shortening (VAG), diarrhea, dietary changes (DIET), menopause, moderate nausea/vomiting (NV), rectal bleeding, sexual dysfunction, and urinary self-catheterization (USC). Descriptive statistics, Kruskal-Wallis, Mann Whitney U, Wilcoxon signed-ranks tests and correlation coefficients were used for statistical analysis.
Results
78 patients participated in the study. Median age was 44.1 years (range 24.9–67.8). Median time since treatment completion was 31.2 months (range 1.0–113.3). The health states rated as most favorable by VAS were also rated as most favorable by SG. Increasing age was associated with higher VAS scores for menopause and VAG (p=0.04 and 0.036). African-Americans had higher VAS scores for DIET (p=0.05), sexual dysfunction (p=0.028), and diarrhea (p=0.05) when compared to Hispanic and non-Hispanic white patients. Women receiving radiation had more favorable VAS scores for menopause compared to women undergoing radical hysterectomy (p=0.05). Women receiving chemotherapy rated USC less favorably by VAS score compared to those not receiving chemotherapy (p=0.045).
Conclusions
Multiple demographic and clinical factors influence the severity of treatment-related adverse effects perceived by women surviving cervical cancer. A better understanding of factors influencing patient preferences regarding treatment side effects will allow providers to formulate care better tailored to the individual desires of each patient.
