Factors Influencing Patient Decision-Making in the Treatment of Muscle-Invasive Bladder Cancer.

BACKGROUND

In 2023, an estimated 82,290 individuals were diagnosed with bladder cancer in the United States. For muscle-invasive bladder cancer (MIBC), the American Urological Association recommends offering radical cystectomy with cisplatin-based neoadjuvant chemotherapy. However, patients are increasingly requesting alternative treatments.

OBJECTIVE

To describe factors influencing selection of radical cystectomy with cisplatin-based neoadjuvant chemotherapy (NAC + RC), radical cystectomy monotherapy (RC), or tri-modality therapy (TMT) among patients with MIBC.

METHODS

Individual, semi-structured phone interviews were conducted with 18 adults who underwent MIBC treatment at the University of North Carolina, recruiting six patients each from three treatment groups: 1) NAC + RC, 2) RC, and 3) TMT. Interview transcriptions were qualitatively analyzed using QSR NVivo, with major themes and sub-themes extracted. Patients also completed the Shared Decision-Making Questionnaire (SDM-Q-9; range 0-100).

RESULTS

Concern for survival and risks, quality of life, and varied patient preferences for involvement influenced the decision-making process. Concern surrounding sexual function, bladder preservation, and urostomy bags drove patients towards TMT. High levels of shared decision-making were observed overall, with a median SDM-Q-9 score of 95 (IQR 89-100). Patients undergoing TMT reported the highest median SDM-Q-9 score (97, IQR 94-100), while those receiving radical cystectomy alone had the lowest (66, IQR 37-96).

CONCLUSIONS

Patients with MIBC described a multifaceted treatment decision-making process, highlighting key influences, concerns, and unmet needs. Understanding this process can help address misconceptions and align treatment choices with patient goals. Physicians can use these insights to engage in shared decision-making, ultimately improving patient experiences and outcomes.
