Comprehensive geriatric assessment in elderly patients with newly diagnosed aggressive non-Hodgkin lymphoma treated with multi-agent chemotherapy

Systematic nutritional screening and assessment in older patients: Rationale for its integration into oncology practice

As the global population ages, so does the number of older people being diagnosed, treated and surviving cancer. Challenges to providing appropriate healthcare management stem from the heterogeneity common in this population. Although malnutrition is highly prevalent in older people with cancer, ranging between 30 % and 80 % according to some analyses, is associated with frailty, and has been shown to be a major risk factor for poor treatment response and worse overall survival, addressing nutrition status is not always a priority among oncology healthcare providers. Evaluation of nutritional status is a two-step process: screening identifies risk factors for reduced nutritional intake and deficits that require more in-depth assessment. Screening activities can be as simple as taking weight and BMI measurements or using short nutritional questionnaires and asking the patient about unintentional weight loss to identify potential nutritional risk. Using geriatric assessment, deficits in the nutritional domain as well as in others reveal potentially reversible geriatric and medical problems to guide specific therapeutic interventions. The authors of this paper are experts in the fields of geriatric medicine, oncology, and nutrition science and believe that there is not only substantial evidence to support regularly performing screening and assessment of nutritional status in older patients with cancer, but that these measures lead to the planning and implementation of patient-centered approaches to nutrition management and thus enhanced geriatric-oncology care. This paper presents rationale for systematic nutrition screening and assessment in older adults with cancer.

The Haemato-Oncology Frailty (HOF) score to assess frailty in lymphoma

Morbidity and mortality during chemotherapy in older adults with haematological malignancy can be unpredictable. The Haemato-Oncology Frailty (HOF) score was previously found to predict outcomes in a cohort of patients with plasma cell myeloma. In this study, we assess its utility in assessing frailty in patients with lymphoma, and compare its performance to that of two other frailty scores. The HOF score was able to predict progression-free survival in this population, and was also shown to have potential in assessing the dynamism of frailty during chemotherapy. It performed well when compared to the Charlson Comorbidity Index (CCI) score and the Haematopoietic Cell Transplantation-Specific Comorbidity Index (HCTCI), although the study was not powered to assess for non-inferiority. The HOF score is a new score with the potential for application in different haematological malignancies.

Prognostic relevance of sarcopenia, geriatric, and nutritional assessments in older patients with diffuse large B-cell lymphoma: results of a multicentric prospective cohort study

This prospective study aimed to investigate the prognostic effect of sarcopenia, geriatric, and nutritional status in older patients with diffuse large B-cell lymphoma (DLBCL). Ninety-five patients with DLBCL older than 70 years who were treated with immunochemotherapy were included. The lumbar L3 skeletal muscle index (L3-SMI) was measured by computed tomography at baseline, and sarcopenia was defined as low L3-SMI. Geriatric assessment included G8 score, CIRS-G scale, Timed Up and Go test, and instrumental activity of daily living. Nutritional status was assessed using the Mini Nutritional Assessment and the body mass index, and several scores used in the literature incorporating nutritional and inflammatory biomarkers, namely the Nutritional and inflammatory status (NIS), Geriatric Nutritional Risk Index, Prognostic Nutritional Index, and Glasgow Prognostic Score.Fifty-three patients were considered sarcopenic. Sarcopenic patients displayed higher levels of inflammation markers and lower levels of prealbumin than non-sarcopenic patients. Sarcopenia was associated with NIS, but was not associated with severe adverse events and treatment disruptions. They were, however, more frequent among patients with elevated NIS. Sarcopenia did not appear in this study as a prognostic factor for progression-free survival (PFS) or overall survival (OS). However, NIS emerged as predictive of the outcome with a 2-year PFS rate of 88% in the NIS ≤ 1 group and 49% in the NIS > 1 group and a significant effect in a multivariate analysis for both PFS (p = 0.049) and OS (HR = 9.61, CI 95% = [1.03-89.66], p = 0.04). Sarcopenia was not associated with adverse outcomes, but was related to NIS, which appeared to be an independent prognostic factor.

Improving care for older adults with hematological malignancies in India: Conquering the challenge

In India, the number of older adults is steadily increasing and expected to reach around 200 million by 2030. Along with demographic change, India is experiencing a shift in family structure from multi-generational to nuclear families, affecting the social and psychological support available to older adults. The majority of hematological malignancies are diagnosed after the age of 60 years. Multiple issues associated with ageing, denoted as geriatric impairments, adversely affect the care of patients with cancer. Geriatric assessment and management is conspicuously underutilized and missing from the medical education curriculum in developing countries including India. Geriatric assessments may provide valuable information for the care of older adults with hematological malignancies, but incorporating geriatrics into the care of older patients with cancer in India will require knowledge of different approaches and consideration of the local healthcare context. In this article we will discuss the distinctive considerations in caring for older adults with hematological malignancies in India and to examine the unmet needs, challenges, and opportunities in improving the care of this population in the Indian context.

Geriatric assessment in hematology scale predicts treatment tolerability in older patients diagnosed with hematological malignancies: The RETROGAH study

INTRODUCTION

The GAH (Geriatric Assessment in Hematology) scale is a psychometrically valid tool aimed at identifying older patients with hematological malignancies at higher risk of treatment-related toxicity. Our objective in this study was to determine the weights for each dimension of the GAH scale and the cut-off point to reliably predict treatment tolerability in this population, estimated by a weighted receiver operating characteristic (ROC) analysis and quantified by the area under the curve (AUC).

MATERIAL AND METHODS

The RETROGAH was a retrospective cohort study including 126 patients who had previously participated in the GAH study. Patients were ≥ 65 years old with newly diagnosed myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML), multiple myeloma (MM), or chronic lymphoid leukemia (CLL) and treated with standard front-line therapy within three months after having completed the GAH scale.

RESULTS

The optimal cut-off value of the GAH total score to discriminate patients at higher risk of treatment toxicity was 42, with 68.5% sensitivity and 55.8% specificity. Using this value, 66.1% of patients evaluated were found to develop some type of toxicity. The AUC was 0.6259 (95% CI: 0.512-0.739; p = 0.035).

DISCUSSION

The GAH scale not only would enable clinicians to individualize therapy based on individual risk of toxicity but also discriminate patients that will benefit most from intensive treatments from those requiring an adapted approach. While futures studies in clinical practice may improve the model and overcome its limitations, the GAH scale should not be used alone when making treatment decisions.

Impact of therapeutic management and geriatric evaluation on patient of eighty years and older with diffuse large B-cell lymphoma on survival: A systematic review

BACKGROUND

Diffuse large B cell lymphoma (DLBCL) is an aggressive disease. The first-line treatment is well defined in young patients; however, in oldest old patients treatment remains unclear.

OBJECTIVES

To investigate the impact of therapeutics management and geriatric evaluation on survival in aged patients with DLBCL.

METHODS

We performed a systematic review of PubMed and COCHRANE databases of published report on elderly patients (median age 80 and above) with DLBCL, from January 2002 to January 2020.

RESULTS

We included 32 studies (6 prospective and 26 retrospective). Patients treated with anthracyclines-containing chemoimmunotherapy had a 2-year overall survival (OS) of 59%-74.3% in prospective studies and 48.1-64.6% in retrospective studies. With less intensive treatment without anthracyclines, 2-year OS was 28%-53%. Without specific treatment, median OS was 2 months. History of falls and severe comorbidities were associated with a decreased survival.

CONCLUSIONS

Chemoimmunotherapy with anthracyclines increases survival in selected very elderly patients in comparison with less intensive regimen. Geriatric assessment, in particular altered mobility disorders and severe comorbidities, is predictive of survival and should be associated with the therapeutic decision. More comparative studies are needed to guide the management of frailer patients.

Frailty in Patients With Hematologic Malignancies and Those Undergoing Transplantation: A Scoping Review

PROBLEM IDENTIFICATION

Although frailty is an important parameter in treatment planning and in predicting prognosis and overall survival among patients with hematologic malignancies and recipients of hematopoietic stem cell transplantation, frailty assessment tools are not standardized in clinical care settings. The purpose of this article is to provide an overview of the literature on frailty assessment tools in these patient populations.

LITERATURE SEARCH

A systematic search of CINAHL®, Embase®, MEDLINE®, PubMed®, and Web of Science was performed using keywords and controlled vocabulary for the concepts "bone marrow transplants," "hematologic neoplasms," and "frailty."

DATA EVALUATION

Extracted data included study type, diagnosis, transplantation status, frailty tools used, and outcome measures.

SYNTHESIS

A systematic search resulted in 24 studies that met the inclusion criteria. There were significant differences in how various groups define and assess frailty.

IMPLICATIONS FOR PRACTICE

Addressing the lack of standardized frailty assessments will assist healthcare providers to routinely integrate frailty measures in clinical assessments to identify those at risk for poor outcomes, improving personalized care.

Treatment Regimens for Immunocompetent Elderly Patients with Primary Central Nervous System Lymphoma: A Scoping Review

Simple Summary

Most patients diagnosed with primary central nervous system lymphoma (PCNSL) are 60 years or older and tend to have a poor prognosis. Evidence to guide and optimize treatment choices for these vulnerable patients is limited. We performed a scoping review to identify and describe all relevant clinical studies investigating chemotherapies and combinations of chemotherapies (including high-dose chemotherapy followed by autologous stem cell transplantation (HCT-ASCT)) in elderly PCNSL patients. In total, we identified six randomized controlled trials, 26 prospective and 24 retrospective studies (with/without control group). While most studies investigated protocols based on ‘conventional’ chemotherapy treatment, data evaluating HCT-ASCT in the elderly were scarce, and the generalizability of the only RCT published is questionable. Considering the poor prognosis of these patients and their need for more effective treatment options, a thoroughly planned randomized controlled trial comparing HCT-ASCT with ‘conventional’ chemoimmunotherapy is urgently needed to evaluate the efficacy of HCT-ASCT.

Abstract

Background: Most patients diagnosed with primary central nervous system lymphoma (PCNSL) are older than 60 years. Despite promising treatment options for younger patients, prognosis for the elderly remains poor and efficacy of available treatment options is limited. Materials and Methods: We conducted a scoping review to identify and summarize the current study pool available evaluating different types and combinations of (immuno) chemotherapy with a special focus on HCT-ASCT in elderly PCNSL. Relevant studies were identified through systematic searches in the bibliographic databases Medline, Web of Science, Cochrane Library and ScienceDirect (last search conducted in September 2020). For ongoing studies, we searched ClinicalTrials.gov, the German study register and the WHO registry. Results: In total, we identified six randomized controlled trials (RCT) with 1.346 patients, 26 prospective (with 1.366 patients) and 24 retrospective studies (with 2.629 patients). Of these, only six studies (one completed and one ongoing RCT (with 447 patients), one completed and one ongoing prospective single arm study (with 65 patients), and two retrospective single arm studies (with 122 patients)) evaluated HCT-ASCT. Patient relevant outcomes such as progression-free and overall survival and (neuro-)toxicity were adequately considered across almost all studies. The current study pool is, however, not conclusive in terms of the most effective treatment options for elderly. Main limitations were (very) small sample sizes and heterogeneous patient populations in terms of age ranges (particularly in RCTs) limiting the applicability of the results to the target population (elderly). Conclusions: Although it has been shown that HCT-ASCT is probably a feasible and effective treatment option, this approach has never been investigated within a RCT including a wide range of elderly patients. A RCT comparing conventional (immuno) chemotherapy with HCT-ASCT is crucial to evaluate benefit and harms in an un-biased manner to eventually provide older PCNSL patients with the most effective treatment.

Development and validation of a prediction model for 1-year mortality among older adults with Hodgkin Lymphoma who receive dose-intense chemotherapy

BACKGROUND

Older adults with Hodgkin Lymphoma (HL) have poorer outcomes than younger patients. There are little data about which baseline patient and disease factors inform prognosis among older patients. We sought to create a prediction model for 1-year mortality among older patients with new HL who received dose-intense chemotherapy.

METHODS

We included adults ≥65 years old with a new diagnosis of classical HL between 2000-2013 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset who received full-regimen chemotherapy. Through a non-random 2:1 split, we created development and validation cohorts. Multiple imputation was used for missing data. Using stepwise selection and logistic regression, we identified predictive variables for 1-year mortality. The model was applied to the validation cohort. A final model was then fit in the full cohort.

RESULTS

We included 1315 patients. In the development cohort (n = 813), we identified significant predictors of 1-year mortality including age, Charlson comorbidity index (CCI), B symptoms at diagnosis, and advanced stage at diagnosis. The c-statistic was 0.70. When this model was applied to the validation cohort (n = 502), the c-statistic was 0.65. Predictors of 1-year mortality in the final model were CCI (OR = 1.41), B symptoms (OR = 1.54), advanced stage (OR = 1.44), and older age at diagnosis (OR = 1.33).

CONCLUSION

We present a prediction model for use among older adults with HL who receive intensive chemotherapy. We identify risk factors for death within 1 year of diagnosis. Future work will build upon prognostication and shared decision-making after diagnosis for this population.

Challenges and Opportunities in the Management of Diffuse Large B-Cell Lymphoma in Older Patients

Most patients with diffuse large B-cell lymphoma (DLBCL) are diagnosed at age 60 years or older. Challenges to effective therapy among older individuals include unfavorable biologic features of DLBCL, geriatric vulnerabilities, suboptimal treatment selection, and toxicities of cytotoxic chemotherapy. Wider application of geriatric assessments may help identify fit older patients who benefit from standard immunochemotherapy without unnecessary dose reductions. Conversely, attenuated regimens may provide a better balance of risk and benefit for selected unfit or frail patients. Supportive care with the use of corticosteroid-based prephase, prophylactic growth factors, and early institution of supportive and palliative care can help maximize treatment tolerance. Several novel or emerging therapies have demonstrated favorable toxicity profiles, thus facilitating effective treatment for elderly patients. In the relapsed or refractory setting, patients who are not candidates for stem cell transplantation can benefit from newly approved options including polatuzumab vedotin-based combinations or tafasitamab plus lenalidomide, which may have higher efficacy and/or lower toxicity than historical chemotherapy regimens. Chimeric antigen receptor T-cell therapy has been successfully applied to older patients outside of clinical trials. In the first-line setting, emerging immunotherapy options (bispecific antibodies) and targeted therapies (anti-CD20 antibodies combined with lenalidomide and/or B-cell receptor inhibitors) may provide chemotherapy-free approaches for DLBCL. Enrolling older patients in clinical trials will be paramount to fully examine potential efficacy and toxicity of these strategies. In this review, we discuss recent advances in fitness stratification and therapy that have expanded curative options for older patients, as well as future opportunities to improve outcomes in this population. IMPLICATIONS FOR PRACTICE: Management of diffuse large B-cell lymphoma in older patients poses challenges due to aggressive disease biology and geriatric vulnerability. Although R-CHOP remains standard first-line treatment, geriatric assessment may help evaluate patients' fitness for immunochemotherapy. Corticosteroid prephase, prophylactic growth factors, and early palliative care can improve tolerance of treatment. Novel salvage options (polatuzumab vedotin-based combinations, tafasitamab plus lenalidomide) or chimeric antigen receptor T-cell therapy should be considered in the relapsed or refractory setting for patients ineligible for stem cell transplantation. Emerging immunotherapies (bispecific antibodies) and targeted therapies provide potential first-line chemotherapy-free approaches, which need to be rigorously assessed in clinical trials that involve geriatric patients.

The Frailty Syndrome: A Critical Issue in Geriatric Oncology

The number of older adults with cancer is growing in the United States, and there is a relative paucity of data relating the presence of frailty with its outcomes of interest. The authors present the surgical oncology, radiation oncology, and medical oncology literature with respect to the presence of frailty in older adults with cancer. More research is needed to understand how the presence of frailty should be used by surgical, radiation, and medical oncologists to guide patient counseling and treatment planning.

Pilot prospective study of Frailty and Functionality in routine clinical assessment in allogeneic hematopoietic cell transplantation

A Frailty and Functionality evaluation for alloHCT was implemented using existing resources. We describe the implementation of this evaluation across all ages and at first consultation, and correlate results with posttransplant outcomes in 168 patients. The evaluation consists of: Clinical Frailty Scale (CFS), Instrumental Activities of Daily Living (IADL), grip strength (GS), timed up and go test (TUGT), self-rated health question (SRH), Single question of Falls, albumin and C-Reactive Protein (CRP) levels. Median time to perform the evaluation was 5-6 min. Median age was 58 years (range: 19-77) and median follow-up was 5.3 months. TUGT > 10 s (HR 2.92; p = 0.003), raised CRP (HR 4.40; p < 0.001), and hypoalbuminemia (HR 2.10; p = 0.043) were significant risk factors for worse overal survival (OS). CFS ≥ 3 (HR 3.11; p = 0.009), TUGT > 10 s (HR 3.47; p = 0.003), GS (HR 2.56; p = 0.029), SRH (<excellent) (HR 3.8 × 10⁶; p < 0.001), elevated CRP (HR 11.8; p < 0.001), and hypoalbuminemia (HR 4.6; p < 0.001), were significant predictors for worse non relapse mortality (NRM). On multivariable analysis, TUGT > 10 s and raised CRP were significant predictors for worse OS and NRM. SRH (<excellent) was a significant predictor for higher NRM. Frailty and Functionality can be assessed in routine clinical practice in alloHCT and may be predictive of short-term outcomes.

Nutritional status and interventions for patients with cancer - A systematic review

BACKGROUND

Malnourishment is commonly seen in ageing, cancer and many chronic conditions, and is associated with poorer prognosis.

AIM

We set out to collect all currently available evidence on the association between nutritional status assessed with a validated screening tool and prognosis or course of treatment in older patients with cancer, and on the benefit of nutritional interventions in improving these outcomes.

METHODS

A systematic search in MEDLINE and EMBASE.

RESULTS

We included 71 studies on the association between nutritional status and outcome in (older) patients with cancer and 17 studies on the benefit of nutritional interventions in improving outcomes in this patient population. There is a significant association between nutritional status and increased intermediate- and long-term mortality (hazard ratio 1.87 (95% confidence interval 1.62-2.17). Those with poorer nutritional status were less likely to complete oncologic treatment according to plan and had higher health care consumption. Benefit of dietary interventions was limited although dietary counselling may lead to improved quality of life while nutritional support may lead to a decrease in post-operative complication rates.

CONCLUSION

Nutritional status is associated with poorer survival, decreased treatment completion and higher health care consumption and nutritional interventions are only able to negate these negatives outcome to a very limited degree.

Nutritional status according to the mini nutritional assessment (MNA)® as potential prognostic factor for health and treatment outcomes in patients with cancer - a systematic review

Background

Patients with cancer have an increased risk of malnutrition which is associated with poor outcome. The Mini Nutritional Assessment (MNA®) is often used in older patients with cancer but its relation to outcome is not known.

Methods

Four databases were systematically searched for studies relating MNA-results with any reported outcome. Two reviewers screened titles/abstracts and full-texts, extracted data and rated the risk of bias (RoB) independently.

Results

We included 56 studies which varied widely in patient and study characteristics. In multivariable analyses, (risk of) malnutrition assessed by MNA significantly predicts a higher chance for mortality/poor overall survival (22/27 studies), shorter progression-free survival/time to progression (3/5 studies), treatment maintenance (5/8 studies) and (health-related) quality of life (2/2 studies), but not treatment toxicity/complications (1/7 studies) or functional status/decline in (1/3 studies). For other outcomes – length of hospital stay (2 studies), falls, fatigue and unplanned (hospital) admissions (1 study each) – no adjusted results were reported. RoB was rated as moderate to high.

Conclusions

MNA®-result predicts mortality/survival, cancer progression, treatment maintenance and (health-related) quality of life and did not predict adverse treatment outcomes and functional status/ decline in patients with cancer. For other outcomes results are less clear. The moderate to high RoB calls for studies with better control of potential confounders.

Geriatric assessment in older patients with a hematologic malignancy: a systematic review

The aim of this systematic review is to give an update of all currently available evidence on the relevance of a geriatric assessment in the treatment of older patients with hematologic malignancies. A systematic search in MEDLINE and EMBASE was performed to find studies in which a geriatric assessment was used to detect impaired geriatric domains or to address the association between geriatric assessment and survival or clinical outcome measures. The literature search included 4,629 reports, of which 54 publications from 44 studies were included. Seventy-three percent of the studies were published in the last 5 years. The median age of the patients was 73 years (range, 58-86) and 71% had a good World Health Organization (WHO) performance status. The median prevalence of geriatric impairments varied between 17% and 68%, even in patients with a good WHO performance status. Polypharmacy, nutritional status and instrumental activities of daily living were most frequently impaired. Whereas several geriatric impairments and frailty (based on a frailty screening tool or summarized geriatric assessment score) were predictive for a shorter overall survival, WHO performance status lost its predictive value in most studies. The association between geriatric impairments and treatment-related toxicity varied, with a trend towards a higher risk of (non-)hematologic toxicity in frail patients. During the follow-up, frailty seemed to be associated with treatment non-completion, especially when patients were malnourished. Patients with a good physical capacity had a shorter stay in hospital and a lower rate of hospitalization. Geriatric assessment, even in patients with a good performance status, can detect impaired geriatric domains and these impairments may be predictive of mortality. Moreover, geriatric impairments suggest a higher risk of treatment-related toxicity, treatment non-completion and use of healthcare services. A geriatric assessment should be considered before starting treatment in older patients with hematologic malignancies.

Comorbidity assessment to determine prognosis in older adult patients with classical Hodgkin lymphoma

The clinical management of older adult patients with Hodgkin lymphoma (HL) remains a major challenge. The aim of this study was to evaluate the impact of comorbidity assessment according to a standardized approach, the Cumulative Illness Rating Scale (CIRS), on prognosis in patients with classical HL aged 60 years and older. We studied 76 consecutive older adult patients with HL (median age 69 y, range 60-84) who had been treated in our institution between 1999 and 2018. Comorbidity was assessed at diagnosis according to CIRS. Anthracycline-containing chemotherapy with curative intent was administered in 59 (78%) patients. We identified 41 (54%) patients with at least one severe comorbidity rated on CIRS grade ≥ 3. Patients with severe comorbidity were more likely to have advanced-stage disease (P = .003), to have an International Prognostic Score (IPS) > 3 (P = .03), and to not receive anthracycline-containing chemotherapy (P = .008). The probability of overall survival (OS) at 3 years was 88% (95% CI, 71%-95%) in patients without severe comorbidities, while it was only 46% (95% CI, 29%-62%) in patients with a comorbidity CIRS grade ≥ 3 (P = .0001). The impact of comorbidity on prognosis was also evident when restricting the analysis to patients treated with anthracycline-containing therapy. The 3-year OS was 93% (95% CI, 76%-98%) (P = .004) in patients without severe comorbidity and 72% (95% CI, 47%-87%) in patients with severe comorbidity (P = .004). In a multivariate analysis, presence of comorbidity, but not age, was a significant factor for OS. Therefore, we conclude that a significant proportion of older adult patients with HL has severe comorbidity on the CIRS scale, which impacts more importantly than age on prognosis.

Ready for prime time: role for geriatric assessment to improve quality of care in hematology practice

Older adults represent the growing majority of patients diagnosed with hematologic disorders, yet they remain underrepresented on clinical trials. Older patients of the same chronologic age differ from one another with varying comorbidity and functional reserve. The concepts of frailty and resilience are important to patient-centered care and are patient and setting specific. The use of geriatric assessment to inform tailored decision making and management can personalize care for older adults with hematologic malignancies. This article will highlight available evidence to support the role of geriatric assessment measures to enhance quality of care for older adults diagnosed with hematologic malignancies.

Ready for prime time: role for geriatric assessment to improve quality of care in hematology practice

These 2 reviews respectively examine the value and utility of geriatric assessment (GA) tools and discuss the role of GA in the clinical management of patients with hematologic malignancies.

Comprehensive Geriatric Assessment: Interprofessional Team Recommendations for Older Adult Women With Breast Cancer

BACKGROUND

Geriatric oncology incorporates comprehensive geriatric assessment (CGA) and traditional oncology care.

OBJECTIVES

The aims are to identify limitations reflected by mean scores on the CGA instruments and describe the CGA recommendations documented in the medical record.

METHODS

CGA was administered and consisted of the Timed Up and Go Test, the Activities of Daily Living Scale, the Instrumental Activities of Daily Living Scale, grip strength, falls, pain, the Brief Fatigue Inventory, the Pittsburgh Sleep Quality Index, the Geriatric Depression Scale, the Mini-Cog, and the Mini Nutritional Assessment. CGA recommendations were obtained from the medical record. Descriptive statistics were used to analyze the data.

FINDINGS

Most recommendations were for general cancer treatment, followed by fall referral/education.

Predictive value of each geriatric assessment domain for older patients with cancer: A systematic review

BACKGROUND

A geriatric assessment (GA) is increasingly used to help guide treatment decisions in older patients with cancer. However, there is no consensus regarding which domains should be included in the GA. In addition, the field of geriatric oncology moves very fast and as a result many new studies have been published since the last review in 2015. Therefore, the objective of this systematic review is to evaluate which domains of the GA could predict patient-related treatment outcomes of older patients with cancer and thereby should be included in a GA.

METHODS

A systematic literature search was performed for publications in English or Dutch between September 2006 and July 2017 addressing the association between individual domains of the GA and mortality, postoperative complications, or systemic treatment-related outcomes in older patients with cancer.

RESULTS

Eight different domains were evaluated in 46 publications, namely functional status, nutritional status, cognition, mood, physical function, fatigue, social support, and falls. All eight domains were predictive for at least one of the investigated outcomes but the results were quite variable across studies. Physical function and nutritional status were the domains most often associated with mortality and systemic treatment-related outcomes, and the domain physical function was most often associated with postoperative complications.

CONCLUSION

Overall, this review demonstrates that the GA should minimally consist of physical function and nutritional status, when the aim is to predict patients-related outcomes of older patients with cancer, although the results are quite heterogeneous. For the other domains, the findings are too inconsistent to draw conclusions about their overall predictive ability.

Multidisciplinary care in the hematology clinic: Implementation of geriatric oncology

Multidisciplinary care is believed to provide benefits to patients with cancer. Tumor board conferences as well aspalliative care or psycho-oncological services have not only become common in oncology, but also in hematology clinics dedicated to the treatment of hematological cancers. Malignant hematological diseases are highly prevalent among older persons. Demographic changes in many countries worldwide are prompting the integration of geriatric principles, methodology, and expertise into existing procedures and infrastructure of multidisciplinary care in hematology clinics. Achieving this goal requires the close collaboration or even incorporation of multiple new professions in the hematology clinic in order to meet the needs of older patients with hematological malignancies who also have comorbidities and functional impairments. We here review the rationale, current evidence, and practical approaches of integrating geriatric oncology into multidisciplinary care in the hematology clinic.

Potentially inappropriate medication use in elderly non-Hodgkin lymphoma patients is associated with reduced survival and increased toxicities

Survival outcomes for elderly lymphoma patients are disproportionally inferior to those of younger patients. We examined medication usage at diagnosis for 171 elderly patients (median age 70 years) with aggressive non-Hodgkin lymphoma treated between 2009 and 2014. At least one potentially inappropriate medication was used in 47% of patients according to the Beers Criteria, 59% experienced treatment delays and/or dose reduction and 65% experienced ≥ grade 3 treatment-related toxicities. We report here for the first time that potentially inappropriate medication use was associated with reduced progression-free survival and overall survival, and increased ≥ grade 3 treatment-related toxicities in multivariate analysis.

Frailty and the management of hematologic malignancies

The majority of blood cancers occur in the elderly. This fact conspires with an aging population in many countries to make rigorous assessment for frailty increasingly important for hematologic oncologists. In this review, we first define frailty and its relevance for patients with hematologic malignancy. Next, we review current data regarding the effect of domains of frailty on outcomes for blood cancers including myelodysplastic syndromes, acute leukemia, non-Hodgkin lymphomas such as chronic lymphocytic leukemia, and multiple myeloma. Finally, after presenting assessment and treatment options for the practicing hematologist, we propose elements of a new research agenda for geriatric hematology: the exchange of age limits for rigorous frailty screening, development of disease-specific measures, and inclusion of functional and patient-reported outcomes alongside survival.

Frontline brentuximab vedotin in combination with dacarbazine or bendamustine in patients aged ≥60 years with HL

Patients aged ≥60 years with treatment-naive Hodgkin lymphoma (HL) have few treatment options and inferior survival due to treatment-related toxicities and comorbidities. This phase 2, nonrandomized, open-label study evaluated brentuximab vedotin (BV) monotherapy (results previously reported), BV plus dacarbazine (DTIC), and BV plus bendamustine. Patients had classical HL and were ineligible for or declined frontline chemotherapy. Twenty-two patients received 1.8 mg/kg BV and 375 mg/m² DTIC for up to 12 cycles, and 20 more patients received 1.8 mg/kg BV plus 90 or 70 mg/m² bendamustine for up to 6 cycles (dose reduced due to toxicity). Subsequent BV monotherapy was allowed. Approximately 30 patients were to receive BV plus bendamustine; however, the incidence of serious adverse events (65%) and 2 deaths on study led to discontinuation of bendamustine and cessation of enrollment. Most patients had stage III/IV disease, and approximately half had ≥3 comorbidities or were impaired in ≥1 aspect that significantly interfered with quality of life. For BV plus DTIC, the objective response rate (ORR) was 100% and the complete remission (CR) rate was 62%. To date, the median progression-free survival (PFS) is 17.9 months. For BV plus bendamustine, the ORR was 100% and the CR rate was 88%. Neither the median PFS nor overall survival was reached. For elderly patients with HL, BV plus DTIC may be a frontline option based on tolerability and response duration. Despite activity, BV plus bendamustine is not a tolerable regimen in these patients. This trial was registered at www.clinicaltrials.gov as #NCT01716806.

Marginal zone lymphoma in elderly and geriatric patients

Approximately 50% of patients with newly diagnosed marginal zone lymphoma (MZL) are of advanced age. For the three subtypes of MZL (extranodal MZL of mucosa-associated lymphoid tissue, splenic MZL, nodal MZL), the median age at diagnosis is around 65-70 years. Due to the lack of larger studies in MZL, little is known of the prevalence of comorbidity, polypharmacy, or geriatric syndromes in older patients with MZL. The impact of these concurrent conditions on the tolerability and feasibility of diagnostic or therapeutic procedures used in MZL has not been specifically investigated. However, some extrapolations can be made from other studies in cancer, thereby raising questions about potential benefits of geriatric assessment in older patients with MZL. Core of this article is a review of recommended diagnostic and therapeutic procedures in MZL in light of potential barriers and complications that might be encountered in elderly and geriatric patients with MZL.

ZLD1122, a novel EZH2 and EZH1 small molecular inhibitor, blocks H3K27 methylation and diffuse large B cell lymphoma cell growth

Here, we reported a novel, selective, small-molecule inhibitor of EZH2 and EZH1 synthesized by us, ZLD1122, which inhibited both EZH1 and wild type and mutant EZH2 activities with nanomolar potency.
