Use of Comprehensive Geriatric Assessment in Oncology Patients to Guide Treatment Decisions and Predict Chemotherapy Toxicity

Predictive value of frailty assessment tools in patients undergoing surgery for gastrointestinal cancer: An observational cohort study

BACKGROUND

Few studies have simultaneously compared the predictive value of various frailty assessment tools for outcome measures in patients undergoing gastrointestinal cancer surgery. Therefore, it is difficult to determine which assessment tool is most relevant to the prognosis of this population.

AIM

To investigate the predictive value of three frailty assessment tools for patient prognosis in patients undergoing gastrointestinal cancer surgery.

METHODS

This single-centre, observational, prospective cohort study was conducted at the Affiliated Lianyungang Hospital of Xuzhou Medical University from August 2021 to July 2022. A total of 229 patients aged ≥ 18 years who underwent surgery for gastrointestinal cancer were included in this study. We collected baseline data on the participants and administered three scales to assess frailty: The comprehensive geriatric assessment (CGA), Fried phenotype and FRAIL scale. The outcome measures were the postoperative severe complications and increased hospital costs.

RESULTS

The prevalence of frailty when assessed with the CGA was 65.9%, 47.6% when assessed with the Fried phenotype, and 34.9% when assessed with the FRAIL scale. Using the CGA as a reference, kappa coefficients were 0.398 for the Fried phenotype and 0.291 for the FRAIL scale (both P < 0.001). Postoperative severe complications and increased hospital costs were observed in 29 (12.7%) and 57 (24.9%) patients, respectively. Multivariate logistic analysis confirmed that the CGA was independently associated with increased hospital costs (odds ratio = 2.298, 95% confidence interval: 1.044-5.057; P = 0.039). None of the frailty assessment tools were associated with postoperative severe complications.

CONCLUSION

The CGA was an independent predictor of increased hospital costs in patients undergoing surgery for gastrointestinal cancer.

Management of Advanced Urothelial Carcinoma in Older and Frail Patients: Have Novel Treatment Approaches Improved Their Care?

Patients with urothelial carcinoma tend to be older and frailer with a large number of chronic medical conditions. This is particularly pronounced in those with unresectable locally advanced and metastatic urothelial carcinoma. Prior to 2016, treatment options in advanced urothelial carcinoma were limited to chemotherapy, and as a result, a large number of patients were not receiving disease-directed management. Over the last 6 years, multiple alternative modalities including immune checkpoint inhibitors and targeted therapies have been introduced. They are being utilized clinically in older and frail patients, but there are limited studies investigating outcomes in these specific populations. Based upon current evidence, age does not impact the efficacy and tolerance of immune checkpoint inhibitors if patients are fit enough to receive therapy. In frailer patients, immune checkpoint inhibitors appear to be safe, but outcomes from largely retrospective studies demonstrate mixed data regarding their efficacy. Although there are indications from clinical trials that enfortumab vedotin, sacituzumab govitecan, and erdafitinib are also efficacious irrespective of age, there is still not enough evidence to draw definitive conclusions about their use in older and frail patients. Regardless, in all older patients with advanced urothelial carcinoma, it is critical to evaluate for frailty through geriatric screening tools and comprehensive assessments. Combining these evaluations with consideration of an individual patient's goals should be the foundation upon which therapeutic decisions are made in this population of patients.
