Fractures frequently occur in older cancer patients: the MD Anderson Cancer Center experience

The Impact of Non-bone Metastatic Cancer on Musculoskeletal Health

PURPOSE OF REVIEW

The purpose of this review is to discuss the musculoskeletal consequences of cancer, including those that occur in the absence of bone metastases.

RECENT FINDINGS

Cancer patients frequently develop cachexia, a debilitating condition reflected by weight loss and skeletal muscle wasting. The negative effects that tumors exert on bone health represents a growing interest amongst cachexia researchers. Recent clinical and pre-clinical evidence demonstrates cancer-induced bone loss, even in the absence of skeletal metastases. Together with muscle wasting, losses in bone demonstrates the impact of cancer on the musculoskeletal system. Identifying therapeutic targets that comprehensively protect musculoskeletal health is essential to improve the quality of life in cancer patients and survivors. IL-6, RANKL, PTHrP, sclerostin, and TGF-β superfamily members represent potential targets to counteract cachexia. However, more research is needed to determine the efficacy of these targets in protecting both skeletal muscle and bone.

Osteosarcopenia is a significant predictor of recurrence and the prognosis after resection for extrahepatic bile duct cancer

PURPOSE

This study examined the impact of osteosarcopenia on recurrence and the prognosis after resection for extrahepatic biliary tract cancer (EBTC).

METHODS

We retrospectively analyzed 138 patients after resection for perihilar cholangiocarcinoma (11), distal cholangiocarcinoma (54), gallbladder carcinoma (30), or ampullary carcinoma (43). Osteosarcopenia is defined as the concomitant occurrence of osteopenia and sarcopenia. We investigated the relationship between osteosarcopenia and the overall survival (OS) and disease-free survival (DFS) in univariate and multivariate analyses.

RESULTS

Osteosarcopenia was identified in 38 patients (27.5%) before propensity score (PS) matching. In the multivariate analysis, the independent recurrence factors were the prognostic nutrition index (p = 0.015), osteosarcopenia (p < 0.001), poorly differentiated adenocarcinoma (p = 0.004), perineural invasion (p = 0.002), and non-curability (p = 0.008), whereas the independent prognostic factors were prognostic nutrition index (p = 0.030), osteosarcopenia (p < 0.001), poorly differentiated adenocarcinoma (p = 0.007), lymphatic invasion (p = 0.018), and non-curability (p = 0.004). After PS matching, there was no significant difference in the variables between the patients with and without osteosarcopenia (n = 34 each). The 5-year DFS and OS after PS matching in patients with osteosarcopenia were significantly worse than in patients without osteosarcopenia (17.6% vs. 38.8%, p = 0.013 and 20.6% vs. 57.4%, p = 0.0005, respectively).

CONCLUSIONS

Preoperative osteosarcopenia could predict the DFS and OS of patients after resection for EBTC.

Comparison of surgical outcomes for hip fracture between older patients with and without cancer: a propensity score matching analysis

Research on the treatment outcomes and mortality of patients with cancer and hip fractures remains limited. We aimed to assess the treatment outcomes and mortality in older patients with cancer and hip fractures. We retrospectively reviewed the data of 1264 patients aged ≥ 60 years treated for hip fractures between January 2005 and April 2022. The operation time, blood transfusion-related indicators, postoperative complications, reoperation rate, length of hospital stay, admission to the intensive care unit, mortality rate, and clinical scores were compared. We also performed survival analysis. Subsequently, 1:1 propensity-score matching was performed. In the unmatched cohort, we compared 273 patients with cancer and 991 controls. The cancer group exhibited a higher incidence of pneumonia (P = 0.025) and higher in-hospital and 1-year follow-up mortality rates (P = 0.044 and P < 0.001, respectively). In the matched cohort, the 1-year mortality rate remained higher in the cancer group (P < 0.001). The control group showed a higher survival rate in both unmatched and matched cohorts (P < 0.001 for both). The surgical outcomes for hip fractures were comparable between patients with and without cancer. We recommend surgical treatment for hip fractures in patients with cancer.

Resistance Training for Patients with Cancer: A Conceptual Framework for Maximizing Strength, Power, Functional Mobility, and Body Composition to Optimize Health and Outcomes

There are many benefits to the addition of exercise to cancer treatment and survivorship, particularly with resistance training regimens that target hypertrophy, bone mineral density, strength, functional mobility, and body composition. These goals are best achieved through a series of individualized high-intensity compound movements that mirror functional mobility patterns and sufficiently stress the musculoskeletal system. As a result of adequate stress, the body will engage compensatory cellular mechanisms that improve the structural integrity of bones and muscles, stimulate metabolism and the immune system, optimize functional performance, and minimize mechanical injury risk. The current evidence suggests that application of the above exercise principles, practiced in a safe environment under expert observation, may offer patients with cancer an effective means of improving overall health and cancer-specific outcomes. The following article poses several important questions certified exercise specialists and physicians should consider when prescribing resistance exercise for patients with cancer.

Incidence of falls and fall-related injuries and their predictive factors in frail older persons with cancer: a multicenter study

Background

Falls and fall-related injuries are a major public health problem. Data on falls in older persons with cancer is limited and robust data on falls within those with a frailty profile are missing. The aim of this study is to investigate the incidence and predictive factors for falls and fall-related injuries in frail older persons with cancer.

Methods

This study is a secondary data analysis from data previously collected in a large prospective multicenter observational cohort study in older persons with cancer in 22 Belgian hospitals (November 2012–February 2015). Patients ≥70 years with a malignant tumor and a frailty profile based on an abnormal G8 score were included upon treatment decision and evaluated with a Geriatric Assessment (GA). At follow-up, data on falls and fall-related injuries were documented.

Results

At baseline 2141 (37.2%) of 5759 included patients reported at least one fall in the past 12 months, 1427 patients (66.7%) sustained an injury. Fall-related data of 3681 patients were available at follow-up and at least one fall was reported by 769 patients (20.9%) at follow-up, of whom 289 (37.6%) fell more than once and a fall-related injury was reported by 484 patients (62.9%). Fear of falling was reported in 47.4% of the patients at baseline and in 55.6% of the patients at follow-up. In multivariable analysis, sex and falls history in the past 12 months were predictive factors for both falls and fall-related injuries at follow-up. Other predictive factors for falls, were risk for depression, cognitive impairment, dependency in activities of daily living, fear of falling, and use of professional home care.

Conclusion

Given the high number of falls and fall-related injuries and high prevalence of fear of falling, multifactorial falls risk assessment and management programs should be integrated in the care of frail older persons with cancer. Further studies with long-term follow-up, subsequent impact on cancer treatment and interventions for fall prevention, and integration of other important topics like medication and circumstances of a fall, are warranted.

25-Hydroxyvitamin D in Cancer Patients Admitted to Palliative Care: A Post-Hoc Analysis of the Swedish Trial 'Palliative-D'

The purpose of this study is to explore 25-hydroxyvitamin D (25-OHD) levels in patients with cancer in the palliative phase in relation to season, sex, age, tumor type, colectomy, and survival. To this end, we performed a post-hoc analysis of ‘Palliative-D’, a randomized placebo-controlled, double-blind trial investigating the effect of daily supplementation with 4000 IU of vitamin D for 12 weeks on pain in patients in palliative cancer care. In the screening cohort (n = 530), 10% of patients had 25-OHD levels < 25 nmol/L, 50% < 50, and 84% < 75 nmol/L. Baseline 25-OHD did not differ between seasons or tumor type and was not correlated with survival time. In vitamin D deficient patients supplemented with vitamin D (n = 67), 86% reached sufficient levels, i.e., >50 nmol/L, after 12 weeks. An increase in 25-OHD was larger in supplemented women than in men (53 vs. 37 nmol/L, p = 0.02) and was not affected by season. In the placebo-group (n = 83), decreased levels of 25-OHD levels were noted during the study period for patients recruited during the last quarter of the year. In conclusion, cancer patients in palliative phase have adequate increase in 25-OHD after vitamin D supplementation regardless of season, age, tumor type, or colectomy.

Quantitative CT Detects Undiagnosed Low Bone Mineral Density in Oncologic Patients Imaged With 18F-FDG PET/CT

PURPOSE

We assessed the prevalence of low bone mineral density (BMD) in oncologic patients undergoing F-FDG PET/CT.

PATIENTS AND METHODS

This is a retrospective analysis of 100 patients who underwent F-FDG PET/CT at a single center from October 2015 till May 2016. Quantitative CT (QCT) was used to assess BMD at the lumbar spine (BMDQCT) and femoral necks (BMDCTXA). SUVmax was used to evaluate metabolic activity of the bone marrow. Risk of osteoporosis-related fractures was calculated with femoral neck BMDCTXA and the FRAX algorithm, which was compared against measurements of CT attenuation of the trabecular bone at L1 (L1HU).

RESULTS

Osteoporosis and osteopenia were respectively present in 16% and 46% of patients 50 years and older. Bone marrow SUVmax was correlated with BMD at the lumbar spine (ρ = 0.36, P < 0.001). Increased age and low marrow SUVmax were associated with low BMDQCT at the lumbar spine (both P < 0.001), whereas increased age, female sex, and low marrow SUVmax were associated with low BMDCTXA at the femoral necks (P < 0.001, P < 0.001, P = 0.01, respectively). L1HU had an area under the curve of 0.95 (95% confidence interval [CI], 0.90-0.99) for detecting increased risk for osteoporosis-related fracture, with best threshold of 125.8 HU (95% CI, 115.7-144.9) yielding sensitivity of 100% (95% CI, 0.92-1.00), specificity of 0.90 (95% CI, 0.76-0.97), and accuracy of 0.91 (95% CI, 0.79-0.97).

CONCLUSIONS

Low BMD is frequent in oncologic patients undergoing F-FDG PET/CT. Decreased F-FDG avidity of the bone marrow correlates with decreased BMD, validating the link between osteoporosis and bone marrow fat. L1HU could be a simple and accurate approach for detecting patients at risk for osteoporosis-related fractures using PET/CTdata.

Geriatric principles for patients with cancer

Cancer is primarily a disease of older persons. Given the heterogeneity of aging, physiological age, rather than chronological age, better expresses the cumulative effect of environmental, medical, and psychosocial stressors, which modifies life expectancy. Comprehensive geriatric assessment, a tool that helps ascertain the physiological age of older individuals, is the gold standard for assessing older adults with cancer. Several international organizations recommend using the geriatric assessment domains to identify unrecognized health problems that can interfere with treatment and predict adverse health-related outcomes, aiding complex treatment decision making. More recently, it has been shown that geriatric assessment-guided interventions improve quality of life and mitigate treatment toxicity without compromising survival. In this review, we discuss the role of comprehensive geriatric assessment in cancer care for older adults and provide the reader with useful information to assess potential treatment risks and benefits, anticipate complications, and plan interventions to better care for older people with cancer.

Nationwide Patterns of Pathologic Fractures Among Patients Hospitalized With Bone Metastases

OBJECTIVES

Pathologic fractures from bone metastases can significantly affect quality-of-life, although it is unclear which patients may be at high risk of this outcome. We aim to determine risk factors for pathologic fracture among patients admitted with bone metastases and to evaluate the association of pathologic fracture with clinical and economic outcomes.

METHODS

The Healthcare Cost and Utilization Project National Inpatient Sample was queried for all patients hospitalized with bone metastases in 2016. Baseline differences between patients with and without pathologic fractures were assessed by χ and analysis of variance testing. Multivariable logistic regression was used to identify factors associated with fractures.

RESULTS

In 2016, 272,275 hospital admissions were associated with a diagnosis of bone metastases, of which 11,960 (4.4%) had a primary diagnosis of pathologic fracture. Patients with pathologic fractures had a longer length-of-hospital-stay (mean 7.5 vs. 6.4 d; P<0.001) and higher cost-of-hospital-stay (mean $23,611 vs. $15,942; P<0.001) compared to patients without pathologic fractures. Primary cancers associated with increased likelihood of pathologic fracture included liver and intrahepatic bile duct (odds ratio [OR] 2.34; 95% confidence interval [CI], 1.65-3.32), multiple myeloma (OR 1.94; 95% CI, 1.31-2.86), and kidney and renal pelvis cancer (OR 1.89; 95% CI, 1.50-2.37).

CONCLUSIONS

Nearly 5% of hospitalizations with bone metastases presented with a concomitant pathologic fracture, which was associated with longer inpatient stay and higher cost. Patients with hepatobiliary, renal cell carcinoma, or multiple myeloma, had a higher likelihood of pathologic fracture. These groups may benefit from increased outpatient monitoring, prophylactic stabilization, or early irradiation.

Falls in older adults with cancer: an updated systematic review of prevalence, injurious falls, and impact on cancer treatment

PURPOSE

This update of our 2016 systematic review answers the following questions: (1) How often do older adults with cancer fall? (2) What are the predictors for falls? (3) What are the rates and predictors of injurious falls? (4) What are the circumstances and outcomes of falls? (5) How do falls in older patients affect subsequent cancer treatment? and a new research question, (6) Which fall reduction interventions are efficacious in this population?

METHODS

MEDLINE, PubMed, CINAHL, and Embase were searched (September 2015-January 25, 2019). Eligible studies included clinical trials and cohort, case-control, and cross-sectional studies published in English in which the sample (or subgroup) included adults aged ≥ 60, with cancer, in whom falls were examined as an outcome.

RESULTS

A total of 2521 titles were reviewed, 67 full-text articles were screened for eligibility, and 30 new studies were identified. The majority involved the outpatient setting (n = 19) utilizing cross-sectional method (n = 18). Sample size ranged from 21 to 17,958. Fall rates ranged from 1.52 to 3.41% per 1000 patient days (inpatient setting) and from 39%/24 months to 64%/12 months (outpatient setting). One out of the 6 research questions contributed to a new finding: one study reported that 1 in 20 older patients experienced impact on cancer treatment due to falls. No consistent predictors for falls/fall injuries and no studies on fall reduction interventions in the geriatric oncology setting were identified.

CONCLUSION

This updated review highlights a new gap in knowledge pertaining to interventions to prevent falls. Additionally, new knowledge also emerged in terms of impact of falls on cancer treatment; however, further research may increase generalizability. Falls and fall-related injuries are common in older adults with cancer and may affect subsequent cancer treatment. Further studies on predictors of falls, subsequent impacts, and fall reduction in the oncology setting are warranted.

Addressing Falls Among Older Oncology Patients Through Complexity Science

Traditional quality assurance processes provide significant opportunities for positive disruption. Doctor of Nursing Practice (DNP) students are well positioned to apply program learning to large-scale change in complex organizations. This article presents an innovative approach for creating a point-of-care interdisciplinary approach to address high fall risk frequencies in ambulatory oncology clinics using complexity leadership principles. Processes for nurse executives to consider for replication of this approach for other challenging clinical situations are suggested using the emerging competence of DNP educated nurses. Adults with cancer who are older than 65 years are at a higher risk for falls than older adults without cancer. Oncology providers and nurses are not routinely screening, documenting, and preventing falls. A fall injury in an older adult with cancer may not only delay or impact cancer treatment but also result in hospitalization, loss of function, and/or death. Increasing awareness of the impact of falls and implementing change within a large ambulatory health care organization requires an interdisciplinary team approach. Complexity theory supports nonlinear change initiated at the grassroots level to create a dynamic movement to bring forth emergence and adaptation. The use of the Centers for Disease Control and Prevention STEADI (Stopping Elderly Accidents, Deaths, and Injuries) initiative will enable oncology professionals to screen, assess, and intervene by collaborating, communicating, and coordinating with other health care specialists to introduce a fall prevention quality improvement system process. Nurse executives need to know about STEADI.

The validity of three malnutrition screening markers among older patients with cancer

Background

Malnutrition is common in older adults with cancer and is associated with adverse clinical outcomes. We assessed and compared the validity of three tools commonly used to screen for malnutrition: The Mini Nutritional Assessment (MNA), weight loss and body mass index (BMI).

Methods

In this retrospective study, we reviewed patients over age 65 with a diagnosis of cancer who were treated at the MD Anderson Cancer Center between 1 January 2013 and 31 March 2017. All patients in this study were evaluated by a trained geriatrician as part of a comprehensive geriatric assessment (CGA). Malnutrition was diagnosed by both CGA and clinical examination. The sensitivity, specificity and Cohen’s κ of each tool was also compared with the clinical diagnosis.

Results

A total of 454 older patients with cancer who had malnutrition information available were included in the analyses. The median age was 78%, and 42% (n=190) were clinically diagnosed with malnutrition at baseline. When the MNA was performed, 105 out of 352 patients (30%) were malnourished, and 122 (35%) at risk of malnutrition. Weight loss >3 kg was seen in 183 out of 359 (51%) patients, and BMI <20 kg/m2 was found in 30 of the 454 (7%) patients. MNA had the highest validity (area under curve (AUC)=0.83) and reliability (κ=0.67), weight loss had moderate validity (AUC=0.73) and reliability (κ=0.46), while BMI had the lowest validity (AUC=0.55) and reliability (κ=0.55).

Conclusions

For clinical practice, MNA should be incorporated for standard assessment/screening for these older patients with cancer.

Bone mineral density correlates with survival after resection of extrahepatic biliary malignancies

BACKGROUND & AIMS

Osteopenia is a condition in which bone mineral density (BMD) is lower than normal, and it is an important determinant of bone fragility. However, the utility of osteopenia in assessing the risks of surgery is unclear. This study investigated the impact of preoperative low BMD on the outcomes in patients undergoing resection of extrahepatic biliary cancers.

METHODS

A retrospective analysis was performed with 181 patients who underwent resections of extrahepatic biliary cancers between 2005 and 2015. Their BMD was measured on preoperative computed tomography images. Overall survival (OS) and recurrence-free survival (RFS) rates were compared according to BMD (normal vs. low), and the prognostic factors after surgery were assessed. Propensity score matching was used to minimize the bias in patient background.

RESULTS

Older age and female were strongly associated with low BMD. These factors were used to construct the propensity score model, which yielded a matched cohort of 52 legs in each group. The OS (21.2% vs. 53.9% at 5 years, p < .001) and RFS (21.8% vs. 64.6% at 5 years, p < .001) rates were significantly lower in patients with low BMD (osteopenia) than in those with normal BMD (non-osteopenia). Multivariable analyses showed that low BMD was an independent factor predictive of poor OS (hazard ratio [HR]: 2.343, 95% confidence interval [CI]: 1.362-4.129, p = .002) and poor RFS (HR: 3.648, 95% CI: 1.986-6.990, p=<.001).

CONCLUSIONS

Preoperative low BMD is closely related to mortality and cancer recurrence after the resection of extrahepatic biliary cancers. BMD screening in patients with cancer should be further highlighted in the oncology field.
