Background: Standard management of muscle-invasive bladder cancer involves radical cystectomy with pelvic lymph node dissection. However, patients may be ineligible for surgery or may wish to avoid the morbidity of cystectomy due to quality of life concerns. Bladder preservation therapies have emerged as alternatives treatment options that can provide comparable oncologic outcomes while maintaining patients' quality of life. Objective: To review bladder preservation therapies, patient selection criteria, and functional and oncologic outcomes for BPT in muscle-invasive bladder cancer. Materials and Methods: We conducted a comprehensive literature review of bladder preservation therapies in Pubmed and Embase. Discussion: The ideal patient for BPT has low-volume T2 disease, absence of CIS, absence of hydronephrosis, and a maximal TURBT with regular surveillance. Technological advancements involving cancer staging, TURBT technique, and chemotherapy and radiation therapy regimens have improved BPT outcomes, with oncologic outcomes now comparable to those of radical cystectomy. Advancements in BPT also includes a heightened focus on improving quality of life for patients undergoing bladder preservation. Preservation strategies with most evidence for use include trimodality therapy and partial cystectomy with pelvic lymph node dissection. Conclusions: This review highlights the breadth of strategies that aim to preserve a patient's bladder while still optimizing local tumor control and overall survival. Future areas for innovation include the use of predictive biomarkers and implementation of immunotherapy, moving the fi eld towards patient-tailored care.
456 Background: Bladder cancer patients’ care is often managed by caregivers, yet caregiving can create a physiologic and emotional burden that compromises the caregivers’ own quality of life (QOL). Our objective was to determine the impact of disease stage on caregiver QOL among a large national cohort of bladder cancer patients. Methods: We performed a cross-sectional survey of bladder cancer caregivers using the Bladder Cancer Advocacy Network Patient Survey Network and Inspire platforms to determine caregiver QOL using the CareGiver QOL questionnaire (CarGOQoL). Caregivers were also queried regarding demographic, socioeconomic and clinical characteristics of their loved one. We present descriptive statistics and a multiple linear regression model to identify factors independently associated with QOL domain score. Results: 132 respondents self-identified as caregivers of patients with bladder cancer. Among respondents, 85% were a spouse, 86% were female, and 97% were white. The mean age was 63 years (range 34 to 72 years) and 73% of respondents completed college. The highest cancer stage for patients was non-invasive in 42%, muscle-invasive in 33%, and metastatic in 24%. On bivariable analysis, stage was associated with leisure and social support but was not associated with global QOL, psychologic or physical well-being, burden, relationship with healthcare, administration and finances, coping, self-esteem or private life. However, on multivariable analysis controlling for age, race, years since diagnosis, and comorbidity, stage was significantly associated with Caregiver QOL (p=0.04). Conclusions: Disease stage significantly impacts QOL among bladder cancer caregivers. As the caregiver is increasingly considered as a stakeholder in survivorship efforts, future interventions should consider targeting social support among caregivers of patients with advanced bladder cancer.
460 Background: Bladder cancer has been linked to financial toxicity with conflicting results regarding the impact of stage. Our objective was to evaluate financial toxicity and work impairment among bladder cancer patients in a large cross-sectional bladder cancer cohort. Methods: We surveyed bladder cancer patients in the Bladder Cancer Advocacy Network Patient Survey Network and Inspire platforms to determine financial toxicity and work impairment. We measured financial toxicity with the COST measure and Work Productivity and Activity Impairment General Health questionnaires. Patients were also queried regarding demographic, socioeconomic and clinical characteristics with specific attention to insurance status, income, and education. Results: 972 respondents self-identified as patients with bladder cancer. Among respondents, 41% were female and 97% were white. The mean age was 67.6 years, ranging from 29 to 93 years. Respondents were highly educated (67% completed college). Most patients identified as having non-invasive bladder cancer (NMIBC, n=578 [63%]); 30% (n=270) had MIBC, 7% (n=63) had metastatic cancer. Although patients with metastatic cancer had higher average COST scores (worse financial toxicity, Table below), stage was not significantly associated with COST on bivariable (p=0.07) or multivariable analysis (p=0.14). Patients with metastatic disease were more likely to report more work time missed and activity impairment due to health on bivariable analysis; only activity impairment was statistically associated with stage on multivariable analysis (p<0.001) when controlling for age, gender, race, comorbidity, insurance, and education. Conclusions: Bladder cancer stage significantly impacts activity impairment but not percentage work time missed due to health nor financial toxicity. [Table: see text]
