Background: Evidence-based guidelines concerning the older head and neck cancer (HNCA) patient are lacking. Accurate patient selection for optimal care management is therefore challenging. We examined if geriatric assessment is indicative of long-term health-related quality of life (HRQOL) and overall survival in this unique population., Methods: All HNCA patients, aged ≥65 years, eligible for curative radio(chemo)therapy were evaluated with the Geriatric-8 (G-8) questionnaire and a comprehensive geriatric assessment (CGA). Euroqol-5 dimensions (EQ-5D) and survival were collected until 36 months post treatment start. Repeated measures ANOVA was applied to analyse HRQOL evolution in 'fit' and 'vulnerable' patients, defined by G-8. Kaplan-Meier curves and cox proportional hazard analysis were established for determination of the prognostic value of geriatric assessments. Quality-adjusted survival was calculated in both patient subgroups., Results: One hundred patients were recruited. Seventy-two percent of patients were considered vulnerable according to CGA (≥2 abnormal tests). Fit patients maintained a relatively acceptable long-term HRQOL, whilst vulnerable patients showed significantly lower median health states. The difference remained apparent at 36 months. Vulnerability, as classified by G-8 or CGA, came forward as independent predictor for lower EQ-5D index scores. After consideration of confounders, a significantly lower survival was observed in patients defined vulnerable according to G-8, compared to fit patients. A similar trend was seen based on CGA. Calculation of quality-adjusted survival showed significantly less remaining life months in perfect health in vulnerable patients, compared to fit ones., Conclusions: G-8 is indicative of quality-adjusted survival, and should be considered at time of treatment decisions for the older HNCA patient.

Objective: We aimed to validate the Freund Clock Drawing Test (CDT), with its predefined cutoff score of ≤4, as a screening tool to detect elderly cancer patients in need of a more in-depth cognitive evaluation within a comprehensive geriatric assessment (CGA)., Methods: Patients aged 70 years or older with a histologically confirmed diagnosis of cancer were evaluated with a full CGA, including CDT and Folstein Mini Mental State Examination (MMSE) as gold standard. Validation of the Freund CDT was defined in terms of diagnostic accuracy of the test through receiver operating characteristics (ROC)-analysis. To accept the Freund CDT as a screening tool, we estimated that the area under the ROC curve (AUC) had to differ significantly from 0.70 with an AUC of at least 0.85., Results: Two hundred elderly cancer patients with a mean age of 79.0 years were included. Four patients were excluded from the analyses because of invalid results. Potential cognitive impairment (MMSE ≤23) was observed in 27.0% of patients. Based on of the AUC ± SE, the Freund CDT showed excellent diagnostic performance (0.95 ± 0.17). Furthermore, it provided excellent sensitivity (94.3%) and high specificity (87.4%)., Conclusions: Our results indicate that the Freund CDT can be used as an initial screening tool to detect elderly cancer patients in need of a more in-depth cognitive assessment within CGA, instead of the MMSE., (Copyright © 2014 John Wiley & Sons, Ltd.)

Objectives: We aimed to determine an optimal cut-off score for the Clock Drawing Test (CDT), scored by the scale of Freund, for efficient screening for cognitive impairment in elderly (cancer) patients within a Comprehensive Geriatric Assessment (CGA) and to compare the Freund CDT to the Mini-Cog., Materials and Methods: Data of 221 elderly (≥70years) patients, comprising of an OncoGeriatric (OG) and General Geriatric (GG) group, were retrospectively reviewed. All patients were evaluated with both the CDT and Mini Mental State Examination (MMSE) as the gold standard. Receiver Operating Characteristics (ROC) analysis was used to determine diagnostic performance. A pre-established algorithm was applied to retrieve Mini-Cog results through a combination of the CDT and the 3-Word Delayed Recall (3-WDR) test (included within MMSE)., Results: Data of 105 OG and 116 GG patients were evaluated. Potential cognitive impairment (MMSE≤23) was detected in 29.5% and 65.8% of patients, respectively. The CDT showed good diagnostic accuracy in the OG (0.88±0.03) and GG (0.85±0.03) group, based on the area under the ROC curve (AUC±SE). CDT (cut-off≤4) provided good sensitivity (80.7%) and specificity (81.1%) in the OG group and excellent sensitivity (89.6%) and moderate specificity (51.3%) in the GG group. Addition of the 3-WDR test, to form the Mini-Cog, resulted in similar positive and negative predictive values for the OG group and higher negative predictive value for the GG group., Conclusion: These data suggest that the Freund CDT, at the cut-off score of ≤4, is promising for use within a CGA. The Mini-Cog might be preferable in the GG population., (Copyright © 2012 Elsevier Inc. All rights reserved.)
