Delivering tailored surgery to older cancer patients: Preoperative geriatric assessment domains and screening tools - A systematic review of systematic reviews.

The onco-geriatric population is increasing and thus more and more elderly will require surgery; an important treatment modality for many cancer types. This population's heterogeneity demands preoperative risk stratification, which has led to the introduction of Geriatric Assessment (GA) and associated screening tools in surgical oncology. Many reviews have investigated the use of GA in onco-geriatric patients. Discrepancies in outcomes between studies currently hamper the implementation of a preoperative GA in clinical practice. A systematic review of systematic reviews was performed in order to investigate assessment tools of the most commonly included GA domains and their predictive ability regarding the adverse postoperative outcomes. All domains - except polypharmacy - were, to a varying degree, associated with different adverse postoperative outcomes. Functional status, comorbidity and frailty were assessed most frequently and were most often significant. The association between domain impairments and adverse postoperative outcomes appeared to be greatly influenced by the study population characteristics and selection bias, as well as the type of assessment tool used due to possible ceiling effects and its sensitivity to detect domain impairments. Frailty seems to be the most important predictor, which underpins the importance of an integrated approach. As it is unlikely that one universal GA will fit all, feasibility, based on the time, expertise, and resources available in daily clinical practice as well as the patient population to hand, should be taken into consideration, when tailoring the 'optimal GA'.

Poor nutritional status is associated with other geriatric domain impairments and adverse postoperative outcomes in onco-geriatric surgical patients - A multicentre cohort study.

BACKGROUND: Nutritional status (NS), though frequently affected in onco-geriatric patients, is no standard part of a geriatric assessment. The aim of this study was to analyse the association between a preoperatively impaired NS and geriatric domain impairments and adverse postoperative outcomes in onco-geriatric surgical patients. METHODS: 309 patients ≥70 years undergoing surgery for solid tumours were prospectively recruited. Nine screening tools were preoperatively administered as part of a geriatric assessment. NS was based on BMI, weight loss and food intake. Odds ratio's (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression analysis. The occurrence of 30-day adverse postoperative outcomes was recorded. RESULTS: At a median age of 76 years, 107 patients (34.6%) had an impaired NS. Decreased performance status and depression were associated with an impaired NS, when adjusted for tumour characteristics and comorbidities (ORPS>1 3.46; 95% CI 1.56-7.67. ORGDS>5 2.11; 95% CI 1.05-4.26). An impaired NS was an independent predictor for major complications (OR 3.3; 95% CI 1.6-6.8). Ten out of 11 patients who deceased had an impaired NS. CONCLUSION: An impaired NS is prevalent in onco-geriatric patients considered to be fit for surgery. It is associated with decreased performance status and depression. An impaired NS is a predictor for adverse postoperative outcomes. NS should be incorporated in a geriatric assessment.

The assessment and management of older cancer patients: A SIOG surgical task force survey on surgeons' attitudes.

AIM: The Surgical Task Force at SIOG (International Society of Geriatric Oncology) designed this survey to explore the surgical oncologists' approach toward elderly cancer patients. METHODS: A web-based survey was sent to all members of ESSO (European Society of Surgical Oncology) and SSO (Society of Surgical Oncology). RESULTS: Two hundred and fifty-one surgeons responded (11% response rate) with a main interest on breast (62.1%), colorectal (43%) and hepatobiliary (27.4%) surgery. Almost all surgeons (>90%) offer surgery regardless the patient's age; only 48% consider mandatory a preoperative frailty assessment. The American Society of Anesthesiologists (ASA) score, nutritional and performance status are most frequently used as screening tools; only 6.4% surgeons use Comprehensive Geriatric Assessment (CGA) in daily practice and collaboration with geriatricians is low (36.3%). If proven to be effective, the majority of surgeons (71%) is prepared to pre-habilitate patients for up to 4 weeks before surgery. One in two surgeons would not offer an operation to patients with impaired cognitive status; conversely, one in three would proceed to surgery regardless of the patient's cognitive status, if functional capacity is conserved. Quality of life and functional recovery are regarded as the most important endpoints in onco-geriatric surgery. Large "real life" prospective observational studies and randomized controlled trials are demanded. CONCLUSION: Age is not perceived as a limitation to surgery. Screening for frailty is limited. A thorough CGA is seldom used and collaboration with geriatricians is rather uncommon. There is a need for clinical investigations focusing on pre-habilitation and other strategies to achieve better functional recovery.

Screening for predictors of adverse outcome in onco-geriatric surgical patients: A multicenter prospective cohort study.

AIMS: The aim of this study was to investigate the predictive ability of screening tools regarding the occurrence of major postoperative complications in onco-geriatric surgical patients and to propose a scoring system. METHODS: 328 patients ≥ 70 years undergoing surgery for solid tumors were prospectively recruited. Preoperatively, twelve screening tools were administered. Primary endpoint was the incidence of major complications within 30 days. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using logistic regression. A scoring system was derived from multivariate logistic regression analysis. The area under the receiver operating characteristic curve (AUC) was applied to evaluate model performance. RESULTS: At a median age of 76 years, 61 patients (18.6%) experienced major complications. In multivariate analysis, Timed Up and Go (TUG), ASA-classification and Nutritional Risk Screening (NRS) were predictors of major complications (TUG>20 OR 3.1, 95% CI 1.1-8.6; ASA ≥ 3 OR 2.8, 95% CI 1.2-6.3; NRS impaired OR 3.3, 95% CI 1.6-6.8). The scoring system, including TUG, ASA, NRS, gender and type of surgery, showed good accuracy (AUC: 0.81, 95% CI 0.75-0.86). The negative predictive value with a cut-off point >8 was 93.8% and the positive predictive value was 40.3%. CONCLUSIONS: A substantial number of patients experience major postoperative complications. TUG, ASA and NRS are screening tools predictive of the occurrence of major postoperative complications and, together with gender and type of surgery, compose a good scoring system.
