Medication risks in older patients (70 +) with cancer and their association with therapy-related toxicity.

BACKGROUND: To evaluate medication-related risks in older patients with cancer and their association with severe toxicity during antineoplastic therapy. METHODS: This is a secondary analysis of two prospective, single-center observational studies which included patients ≥ 70 years with cancer. The patients' medication lists were investigated regarding possible risks: polymedication (defined as the use of ≥ 5 drugs), potentially inappropriate medication (PIM), and relevant potential drug-drug interactions (rPDDI). The risks were analyzed before and after start of cancer therapy. Severe toxicity during antineoplastic therapy was captured from medical records according to the Common Terminology Criteria for Adverse Events (CTCAE). The association between grade ≥ 3 toxicity and medication risks was evaluated by univariate as well as multivariate regression adjusted by ECOG and age. RESULTS: The study cohort comprised 136 patients (50% female, mean age 77 years, 42% hematological malignancies). Before the start of cancer therapy, patients took on average 5 drugs as long-term medication and 52% of patients were exposed to polymedication. More than half of patients used at least one PIM. Approximately one third of patients exhibited rPDDI. The prevalence of medication risks increased after start of cancer therapy. rPDDI were significantly associated with severe overall toxicity (OR, 5.07; p = 0.036; 95% Confidence Interval (CI) 1.11-23.14; toxicity in patients with rPDDI 94.1% (32/34) vs 75.9% (60/79) in patients without rPDDI) and hematological toxicity (OR, 3.95; p = 0.010; 95% CI 1.38-11.29; hematological toxicity in patients with rPDDI 85.3% (29/34) vs 59.5% (47/79) in patients without rPDDI). In the multivariate analysis adjusted by ECOG and age, only the association for rPDDI with hematological toxicity remained statistically significant (OR, 4.51; p = 0.007; 95% CI 1.52-13.38). These findings should be further investigated in larger studies. CONCLUSION: Medication risks are common in older patients with cancer and might be associated with toxicity. This raises the need for tailored interventions to ensure medication safety in this patient cohort.

Comparing the performance of the CARG and the CRASH score for predicting toxicity in older patients with cancer.

OBJECTIVES: To compare the CARG (Cancer and Aging Research Group) and CRASH (Chemotherapy Risk Assessment Scale for High-Age Patients) score regarding the predictive performance for severe toxicity in older patients with cancer. METHODS: We recruited patients ≥70 years and applied the CARG and CRASH score before the start of systemic cancer treatment. The CARG predicts severe overall toxicity; the CRASH additionally predicts hematologic and nonhematologic toxicity. We captured ≥ grade 3 toxicity according to Common Terminology Criteria for Adverse Events (CTCAE) from medical records. Predictive performance was assessed using logistic regression and the area under the receiver operating characteristic curve (ROC-AUC). RESULTS: The study cohort comprised 120 patients (50% female, mean age 77.2 years, 57% solid tumors). The median of the CARG (range 0-23) and the combined CRASH (range 0-12) were 9 and 8, respectively. 81% of patients experienced toxicity; 67% showed hematologic toxicity. The predictive performance of the CARG and the combined CRASH was similar for overall toxicity (CARG: Odds ratio per unit increase (OR) 1.266, P = .015; ROC-AUC 0.681, P = .010; combined CRASH: OR 1.337, P = .029; ROC-AUC 0.650, P = .032). For hematologic toxicity, the hematologic CRASH was a significant predictor and showed numerically a higher ROC-AUC than the CARG which was not statistically different (CARG: OR 1.048, P = .462; ROC-AUC 0.564, P = .271; hematologic CRASH: OR 1.602, P = .007; ROC-AUC 0.665, P = .005). CONCLUSION: Both scores exhibited similar predictive performance for toxicity in older patients with cancer.

Effects of a physical activity programme to prevent physical performance decline in onco-geriatric patients: a randomized multicentre trial.

BACKGROUND: Older adults with cancer experience negative long-term functional effects of both cancer and treatments. Exercise may minimize their age-related and cancer-related functional decline. METHODS: We conducted a multicentre open-label 12 month randomized clinical trial with two parallel arms including participants aged ≥70 years with lymphoma or carcinoma requiring curative treatment. The study started at the beginning of any phase of cancer treatment (surgery, chemotherapy, or radiotherapy). The usual care group (UCG) received the current national recommendations in physical activity (a guideline without specific counselling). The intervention group (IG) received 1 year phoned physical activity advice individually adapted to physical assessment (twice a month during the first 6 months and then monthly). The primary outcome was the proportion of subjects with a 1 year decreased short physical performance battery (SPPB) score of 1 point or more. Physical, cognitive, and clinical secondary outcomes were also investigated. RESULTS: We allocated 301 participants (age 76.7 ± 5.0, female 60.6%) to each group. At baseline, the median SPPB was 10/12 in both groups. Breast was the most frequent tumour site (35.7%). After 1 year, 14.0% of participants in the UCG and 18.7% in the IG had a decrease in SPPB score of 1 point or more (P = 0.772). At 2 years, there was no difference in SPPB, gait speed, International Physical Activity Questionnaire score, and verbal fluency. Subgroup analyses after 2 years showed a decline in SPPB for 29.8% of UCG and 5.0% of IG breast cancer participants (P = 0.006), in 21.7% of UCG and 6.2% of IG female participants (P = 0.019), and in 24.5% of UCG and 11.1% of IG normal nutritional status participants (P = 0.009). Falls, hospitalization, institutionalization, and death rates were similar in both groups. CONCLUSIONS: Personalized phoned physical activity advice had not reduced functional decline at 1 year but provided preliminary evidence that may prevent physical performance decline at 2 years in older adults with breast cancer.

Short-term postoperative physical decline and patient-reported recovery in people aged 70 or older undergoing abdominal cancer resection- A prospective cohort study.

OBJECTIVES: Extensive physical deterioration as a consequence of both cancer and surgical treatment can lead to increased care needs and decreased well-being. Information on short-term physical decline and patient-reported recovery in older patients undergoing abdominal cancer surgery is still sparse. We aimed to describe the short-term changes and study the associations between preoperative physical performance and postoperative mobility, as well as patient-reported recovery in this patient group. MATERIALS AND METHODS: Patients ≥70 years of age waiting for abdominal cancer surgery were included in a prospective cohort study. Physical performance tests were conducted preoperatively and on hospital discharge. Changes from baseline to postoperative values were described, logistic regressions were performed to explore the association between preoperative physical performance and postoperative mobility, and ordinal regression for the association between physical decline and patient-reported recovery. RESULTS: One-hundred forty individuals (mean age 76.0 ±â€¯4.6 years) were included in the analyses. We found the greatest declines in functional leg strength (38%) and walking distance (33%). Twenty participants (15%) were unable to rise from a chair without support on discharge. In the multivariable analyses, better preoperative physical performance was associated with lower odds of limited mobility on discharge. A larger decline in gait speed was associated with greater odds of reporting lower postoperative recovery. CONCLUSIONS: This study adds information regarding the magnitude of short-term physical decline and factors associated with postoperative mobility. It may be important to improve functional leg strength and physical capacity through exercise prior to abdominal cancer surgery to reduce postoperative physical decline.

Better preoperative physical performance reduces the odds of complication severity and discharge to care facility after abdominal cancer resection in people over the age of 70 - A prospective cohort study.

INTRODUCTION: Reduced functional reserve in older people, combined with the surgical stress, may increase the likelihood of adverse postoperative outcomes. The objective of this study was to examine the associations between preoperative physical performance and severity of postoperative complications, length of stay (LoS), and discharge destination in older people after abdominal cancer surgery. METHODS: Between December 2015 and December 2017, a prospective cohort study examined 197 individuals ≥ 70 years of age awaiting abdominal cancer surgery. Measures of physical performance (walking distance, functional leg strength, grip strength, inspiratory muscle strength, gait speed) and self-reported physical activity were conducted preoperatively, and postoperative outcomes were collected within 30 days of surgery. RESULTS: Fifty-four percent experienced at least one postoperative complication at 30-day follow-up, including 10% with severe complications. In the multivariable analysis, better walking distance, functional leg strength, grip strength, inspiratory muscle strength, and gait speed were associated with reduced odds of higher complication severity. Better preoperative inspiratory muscle strength was associated with shorter LoS in hospital, and better preoperative physical activity level, walking distance, grip strength, and maximal walking speed reduced the odds of being postoperatively discharged to further care rather than to home. CONCLUSION: The results emphasize the importance of acknowledging the physical fitness of the older individual rather than chronological age. Objectively measured physical performance is an important addition to conventional risk assessments in preoperative care. This will help to identify patients at high risk and in need of an alternative preoperative pathway, which might include personalized preoperative exercise.
