Abstract
There is a steep linear increase in patients surviving a cancer diagnosis. Clinical solutions that address the high prevalence of cancer-related treatment effects (CRTE) are urgently needed. A stark example of this need is the dearth of screening and treatment programs for cancer related cognitive impairment (CRCI) (colloquially called “chemo-brain”). Up to 75% of cancer patients report neurocognitive changes that leave patients unable to cope with the expectations of employers, colleagues, families, and friends. The prevalence of neurological disorders is 275% higher among adult cancer patients, when compared to an adult cancer-free population. For many adolescent and young adult cancer patients, the onset of CRCI occurs during "cognitive prime time"; a time when individuals are pursuing education, careers, and raising families. To address a gap in CRTE we have implemented a virtual multi-disciplinary intervention to measure and treat CRCI. Our CRCI intervention follows National Comprehensive Cancer Network and American Society of Clinical Oncology (ASCO) guidelines for CRCI. These guidelines indicate a multi-disciplinary approach with emphasis on increasing physical activity levels, cognitive-behavioral therapy, memory adaptive training, mood management, and sleep optimization. Our approach also follows recent ASCO guidelines for nutrition counseling. Our CRCI program utilizes medical oncologists, physician assistants, mental health therapists, registered dietitians, and occupational therapists. A nationally validated patient reported outcome (PRO) measurement, analysis, and reporting platform informs clinical treatment pathways, monitors patient progress, guides clinical decision making, and improves patient/provider communication. Using health status measures for CRCI, and following American Cancer Society and ASCO guidelines, patients are risk-stratified into three personalized cancer survivor care pathways: 1) low-complexity patients; 2) medium-complexity patients; and 3) high-complexity patients. Low-complexity patients baseline PROs score in the normal range, medium-complexity patients are those who score below the norm (moderate to large effect size difference from normal), and high-complexity patients are those who score well below the norm (greater than larger effect size difference from normal). Low-complexity patients are enrolled into a self-management and continuation of care program. Medium-complexity patients are enrolled into a shared care program. High-complexity patients are enrolled into an acute care program. All three clinical pathways include continued risk-factor vital-sign surveillance. Nearly 100% (99%) of patients who enroll in our primary cancer survivor care program complete our PRO baseline (N=80). From a convenient sample of breast cancer patients (N=42), provisional results of patient-specific segmentation analyses reveal a nearly perfect bell-shaped curve, with 51% of the population classified within the definition of medium-complexity and even split of outliers (high-complexity 24% and low-complexity 24%). Additionally, of all patients in our primary cancer survivor care program who completed at least three measurement time points for health status measures of cognitive impartment (N=38), 92% had a positive experience, 71% had a clinically significant improvement in cognitive health, 21% had a no change in cognitive status, and only 8% had a decline in cognitive health. If these data, and PRO implementation approach hold true, this program could be scaled to national and international cancer survivor population suffering from CRCI.
