Tailored therapy in an unselected population of 91 elderly patients with DLBCL prospectively evaluated using a simplified CGA

Geriatric risk model for older patients with diffuse large B-cell lymphoma (GERIAD): a prospective multicenter cohort study

BACKGROUND/AIMS

Optimal risk stratification based on simplified geriatric assessment to predict treatment-related toxicity and survival needs to be clarified in older patients with diffuse large B-cell lymphoma (DLBCL).

METHODS

This multicenter prospective cohort study enrolled newly diagnosed patients with DLBCL (≥ 65 yr) between September 2015 and April 2018. A simplified geriatric assessment was performed at baseline using Activities of Daily Living (ADL), Instrumental ADL (IADL), and Charlson's Comorbidity Index (CCI). The primary endpoint was event-free survival (EFS).

RESULTS

The study included 249 patients, the median age was 74 years (range, 65-88), and 125 (50.2%) were female. In multivariable Cox analysis, ADL, IADL, CCI, and age were independent factors for EFS; an integrated geriatric score was derived and the patients stratified into three geriatric categories: fit (n = 162, 65.1%), intermediate-fit (n = 25, 10.0%), and frail (n = 62, 24.9%). The established geriatric model was significantly associated with EFS (fit vs. intermediate-fit, HR 2.61, p < 0.001; fit vs. frail, HR 4.61, p < 0.001) and outperformed each covariate alone or in combination. In 87 intermediate-fit or frail patients, the relative doxorubicin dose intensity (RDDI) ≥ 62.4% was significantly associated with worse EFS (HR, 2.15, 95% CI 1.30-3.53, p = 0.002). It was related with a higher incidence of grade ≥ 3 symptomatic non-hematologic toxicities (63.2% vs. 27.8%, p < 0.001) and earlier treatment discontinuation (34.5% vs. 8.0%, p < 0.001) in patients with RDDI ≥ 62.4% than in those with RDDI < 62.4%.

CONCLUSION

This model integrating simplified geriatric assessment can risk-stratify older patients with DLBCL and identify those who are highly vulnerable to standard dose-intensity chemoimmunotherapy.

Predictors of Survival, Treatment Modalities, and Clinical Outcomes of Diffuse Large B-Cell Lymphoma in Patients Older Than 70 Years Still an Unmet Medical Need in 2024 Based on Real-World Evidence

BACKGROUND

Diffuse large B-cell lymphoma (DLBCL) especially affects the older population. Old (≥60 years) and very old age (≥80 years) DLBCL patients often present high-risk molecular alterations, lower tolerability to conventional immunochemotherapy, and poor clinical outcomes. In this scenario, attenuated therapeutic strategies, such as the R-MiniCHOP and R-MiniCHOP of the elderly regimens, have emerged for this particularly fragile population. However, the responses, clinical outcomes, and toxicities of these regimens currently remain poorly understood, mainly because these individuals are not usually included in controlled clinical trials.

METHODS

This retrospective, observational, and single-center real-world study included 185 DLBCL, NOS patients older than 70 years treated at the largest oncology center in Latin America from 2009 to 2020. We aimed to assess the outcomes, determine survival predictors, and compare responses and toxicities between three different primary therapeutic strategies, including the conventional R-CHOP regimen and the attenuated R-MiniCHOP and R-MiniCHOP of the elderly protocols.

RESULTS

The median age at diagnosis was 75 years (70-97 years), and 58.9% were female. Comorbidities were prevalent, including 19.5% with immobility, 28.1% with malnutrition, and 24.8% with polypharmacy. Advanced clinical stage was observed in 72.4%, 48.6% had bulky disease ≥7 cm, 63.2% had B-symptoms, and 67.0% presented intermediate-high/high-risk IPI. With a median follow-up of 6.3 years, the estimated 5-year OS and PFS were 50.2% and 44.6%, respectively. The R-MiniCHOP of the elderly regimen had a lower ORR (p = 0.040); however, patients in this group had higher rates of unfavorable clinical and laboratory findings, including hypoalbuminemia (p = 0.001), IPI ≥ 3 (p = 0.013), and NCCN-IPI ≥ 3 (p = 0.002). Although associated with higher rates of severe neutropenia (p = 0.003), the R-CHOP regimen promoted increased OS (p = 0.003) and PFS (p = 0.005) in comparison to the attenuated protocols. Additionally, age ≥ 75 years, high levels of LDH, B-symptoms, advanced clinical stage (III/IV), neutrophilia, and low lymphocyte/monocyte ratio were identified as poor prognostic factors in this cohort.

CONCLUSIONS

In this large and real-life Latin American cohort, we demonstrated that patients with DLBCL, NOS older than 70 years still do not have satisfactory clinical outcomes in 2024, with half of cases not reaching 5 years of life expectancy after diagnosis. Although the conventional R-CHOP offers response and survival advantages over attenuated regimens, its myelotoxicity is not negligible. Therefore, the outcomes reported and the prognostic factors here identified may assist clinicians in the appropriate selection of therapeutic strategies adapted to the risk for old and very old DLBCL patients.

Primary central nervous system lymphoma (PCNSL) in older patients

INTRODUCTION

Primary central nervous system lymphoma (PCNSL) is a rare, chemo and radio-sensitive tumor limited to the central nervous system. The incidence of PCSNL increases notably in the elderly population which represented approximately half of the patients. The limit of 'elderly' population remained debated and nonuniform, including 60 years as a cutoff for brain radiotherapy, 65 years for autologous stem-cell transplantation, and 70 years for the last clinical trials. Current therapeutic options include first line treatment based on high-dose methotrexate based polychemotherapy, consolidation chemotherapy, and adapted autologous stem cell transplantation for highly selected patients. At relapse, single agent targeted therapies or salvage chemotherapy followed by intensive consolidation are promising therapeutic options. Nevertheless, improving management of elderly patients is an urgent medical need that currently remains unresolved.

OBJECTIVE

We will focus on elderly patients with PCNSL and their specificities including clinical presentations, available therapeutic options and adaptations to be made.

CONCLUSION

To improve survival, it will be necessary to personalized and adapt the treatments, to each patient and his comorbidities, to increase their effectiveness and limit their toxicity in this frail population. Finally, inclusion of these patients in clinical trials is one of the major challenges to significantly change PCNSL elderly patient prognosis.

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.

Pretreatment frailty is an independent prognostic factor among elderly patients with B-cell lymphoma undergoing immunochemotherapy: A prospective observational cohort study in Taiwan

BACKGROUND/PURPOSE

Frailty is a common clinical syndrome among the elderly; however, it is frequently neglected in patients with hematological malignancies, especially among the Asian population. This study is aimed to evaluate the prevalence and effect of frailty on survival outcomes in elderly Asian patients with B-cell lymphoma.

METHODS

We prospectively enrolled 76 consecutive patients with age ≥ 65 years and newly diagnosed B-cell lymphoma and were receiving immunochemotherapy in a medical center in Taiwan between August 2016 and December 2017. The frailty of all patients was assessed using a comprehensive geriatric assessment (CGA) within 7 days before immunochemotherapy.

RESULTS

Twenty-seven patients (36%) were allocated to the frail group based on CGA. With a median follow-up duration of 26.5 (range, 1.7-39.8) months, the 1- and 2-year survival rates were 68% and 58%, respectively, for all group of patients. In patients in the non-frail group, the 1-year and 2-year survival rates were 81% and 71%, respectively, compared to 44% and 33%, respectively, in the frail group (hazard ratio [HR], 3.57, 95% confidence interval [CI], 1.74-7.30; p = 0.001). Age ≥ 75years (adjusted HR 2.57, 95% CI 1.02-6.47, p = 0.045), presence of B-symptoms (adjusted HR 2.43, 95% CI 1.05-5.60, p = 0.038), and frailty (adjusted HR 3.03, 95% CI 1.29-7.11, p = 0.011) were independent prognostic factors in the multivariate analysis.

CONCLUSION

Frailty significantly influenced the survival outcome as an independent prognostic factor in elderly patients with B-cell lymphoma undergoing immunochemotherapy. Pretreatment frailty assessment is critical to assist clinicians and patients with B-cell lymphoma with prognosis prediction and counseling on an appropriate treatment goal.

Ideal dose intensity of R-CHOP in diffuse large B-cell lymphoma

INTRODUCTION

The standard of care for diffuse large B-cell lymphoma (DLBCL) is rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). However, its ideal dose intensity varies among cases.

AREAS COVERED

This review provides the latest insights on the dose intensity of R-CHOP for DLBCL patients. Specifically, we discussed the optimal dose intensity for elderly patients, the optimal number of treatment cycles for limited or advanced-stage diseases, and the role of dose-intensified therapies or adding targeted inhibitors.

EXPERT OPINION

Performing a comprehensive or simplified geriatric assessment can distinguish elderly DLBCL patients who will likely benefit from curative R-CHOP. Very elderly or medically unfit patients may need dose reduction in R-CHOP; the Age, Comorbidities, and Albumin index may aid decision-making. Four cycles of R-CHOP followed by two rituximab cycles comprise a new standard for low-risk, limited-stage DLBCL patients. Compared to eight cycles, six cycles of R-CHOP have similar efficacy and fewer toxicities for advanced-stage DLBCL. Dose-intensified therapy is not recommended in most DLBCL cases but may be considered for patients with double (or triple)-hit lymphoma. Applying targeted inhibitors and not merely escalating R-CHOP dose intensity through molecular subtyping will improve the treatment outcome for DLBCL.

Management of elderly patients with malignant lymphoma

More than half of patients with malignant lymphoma are 65 years old or older. The outcome for older patients is poorer than that for younger patients. A poor prognosis is associated with heterogeneity and consists of physical function, performance status, poor nutritional status and various comorbidities. Therefore, attention should be given to serious treatment-related toxicities. Diffuse large B-cell lymphoma is the most frequently diagnosed type of malignant lymphoma. Most patients with diffuse large B-cell lymphoma can be potentially cured with the current standard chemotherapeutic regimen of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone. However, a reduced-dose regimen of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone or alternative treatment options might be suitable for older patients who are frail or unfit and have cardiac comorbidities. A comprehensive geriatric assessment is a potential tool for determining an appropriate therapeutic approach for each older patient. Follicular lymphoma is the second most common type of non-Hodgkin lymphoma, and the disease course is usually characterized by an indolent clinical course. Advanced follicular lymphoma with a high tumor burden has historically been treated with chemoimmunotherapy, but the treatment goal for older patients is relief of symptoms. Incorporating novel targeted agents such as brentuximab vedotin into therapies for older Hodgkin lymphoma patients might be a promising alternative to the anthracycline-containing regimen.

Prescription of Blood Lymphocyte Immunophenotyping in the Diagnosis of Lymphoid Neoplasms in Older Adults

Lymphoid neoplasms are a heterogeneous group of lymphoid neoplastic diseases with multiple presentations, and varying prognoses. They are especially frequent in older patients (OPs) and the atypism of this frail elderly population can make the diagnostic process even more difficult. Blood lymphocyte immunophenotyping (BLI) is essential in rapid noninvasive diagnosis orientation and guides complementary investigations. To our knowledge, BLI prescription has never been evaluated in OPs. We hypothesized that, when there is a suspicion of lymphoid neoplasm in the geriatric population, a BLI is performed in view of various clinical or biological abnormalities. This study aimed to: (1) describe the characteristics of hospitalized OPs having undergone BLI for suspected lymphoid neoplasm, (2) identify the causes leading to BLI prescription, and (3) identify the most profitable criteria for BLI prescription. This was a descriptive retrospective study on 151 OPs aged ≥75 years who underwent BLI over a 2-year period. Regarding BLI prescriptions, eight had lymphocytosis, constituting the “lymphocytosis group” (LG+), while the 143 others had BLI prescribed for reasons other than lymphocytosis (LG−), mainly general weakness and anemia. In the LG−, we compared OPs with positive and negative BLI results. The criteria found to be profitable for BLI prescription were lymphadenopathy, splenomegaly, lymphocytosis, and thrombocytopenia. BLI identified circulating lymphoid neoplasms (positive BLI) in 21/151 OPs, mainly marginal zone lymphoma and chronic lymphocytic leukemia. In polymorbid OPs, as per our study population, the diagnostic and therapeutic complexity explained in part the sole use of indirect and minimally invasive diagnostic techniques such as BLI.

Global Risk Indicator and Therapy for Older Patients With Diffuse Large B-Cell Lymphoma: A Population-Based Study

PURPOSE

To examine the impact of global risk, a measure comprising age, comorbidities, function, and cognitive statuses, on treatment selection and outcomes among older home care recipients with diffuse large B-cell lymphoma.

METHODS

From SEER-Medicare, we selected home care recipients diagnosed with diffuse large B-cell lymphoma in 2011-2015, who had pretreatment Outcome and Assessment Information Set (OASIS) evaluations. We created a global risk indicator categorizing patients as low-, moderate-, or high-risk on the basis of OASIS assessments. We examined the association of global risk with receipt of therapy and among chemotherapy recipients, with mortality, emergency department visits, hospitalization, and intensive care unit admission within 30 days from first treatment in logistic models, reporting adjusted odds ratios (OR) with 95% CI. We compared overall survival across risk groups estimating adjusted hazard ratios.

RESULTS

Of the 1,232 patients (median age, 80 years), 65% received chemotherapy. High-risk patients (v moderate-risk) were less likely to receive any chemotherapy (OR, 0.50; 95% CI, 0.39 to 0.64) and curative regimens (OR, 0.59; 95% CI, 0.40 to 0.86) if treated, although even in the moderate-risk group, only 61% received curative regimens. High-risk patients were more likely to experience acute mortality (OR, 2.24; 95% CI, 1.43 to 3.52), emergency department visits (OR, 1.35; 95% CI, 1.00 to 1.83), hospitalization (OR, 1.60; 95% CI, 1.19 to 2.17), or intensive care unit admission (OR, 1.52; 95% CI, 1.04 to 2.22) and had inferior overall survival (hazard ratio, 1.41; 95% CI, 1.11 to 1.78).

CONCLUSION

Global risk on the basis of OASIS is easily available, suggesting a potential way to improve patient selection for curative treatment and institution of preventive measures.

Geriatric assessment in older adults with Non-Hodgkin lymphoma: A Young International Society of Geriatric Oncology (YSIOG) review paper

Non-Hodgkin lymphoma (NHL) is a disease of older adults, with a median age at diagnosis of 67 years. Treatment in older adults with NHL is challenging. The aging process is associated with a decline in functional reserve that varies among individuals, and results in an increasing risk of treatment-related toxicity and mortality. Chronological age and performance status fail to capture the multidimensional and heterogeneous nature of the aging process. A geriatric assessment (GA) screens multiple geriatric domains and provides a more accurate assessment of functional reserve. Several abbreviated GA tools have been developed for use in oncology clinics and help identify patients at high risk for chemotherapy-related toxicity and mortality. In this review, we explore GA tools validated for use in patients with NHL. We discuss the evidence behind GA-guided treatment in NHL and present a suggested approach to assessing frailty in this patient population.

Electronic FRAIL score as a predictor of treatment outcomes in older patients with diffuse large B-cell lymphoma

INTRODUCTION

Frailty is a significant risk factor for poor outcomes among older patients with diffuse large B-cell lymphoma (DLBCL). We present an automatically derived electronic frailty screening tool (FRAIL score) as a predictor of patient outcomes.

METHODS

Patients aged 70 or over who received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy for DLBCL between 2010 and ` were retrospectively assessed for their FRAIL scores. Measured treatment outcomes included overall survival (OS), progression-free survival (PFS), and treatment-limiting toxicity from chemotherapy.

RESULTS

A total of 96 patients were analysed. When stratified by FRAIL score, the estimated 5-year PFS was 58%, 48% and, 0% for those with scores of 0-1, 2, and 3-5, respectively (p = 0.012). Similarly, the estimated 5-year OS for these respective groups was 60%, 60% and 0% (p = 0.010). Patients with a FRAIL score of 3-5 were also more likely than those with a score of 0-1 to need dose reduction or treatment delay due to toxicity (odds ratio [OR] 12.5, 95% confidence interval [CI] 10.42-109.72) and less likely to complete the six planned cycles of treatment (OR 0.14, 95% CI 0.03-0.77).

CONCLUSION

The FRAIL score is independently predictive of OS, PFS, and treatment-related toxicity in older patients with DLBCL receiving R-CHOP chemotherapy. Once implemented, it provides a quick and accessible method to stratify disease and treatment-related risk among these patients.

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.

Advances in treatment of elderly primary central nervous system lymphoma

The management of older individuals (≥60 years) with primary central nervous system lymphoma remains a clinical challenge. Identification of optimal therapy and delivering adequate dose intensity are two of the major issues in treating elderly patients. Premorbid performance status and comorbidities influence individualised treatment approaches and geriatric assessment tools are increasingly utilised. Optimal induction treatment remains high-dose methotrexate-based immunochemotherapy, delivery is feasible in the majority of patients and the goal of treatment remains achieving complete remission. Consolidation strategies are also relevant in the elderly, aiming to maximise duration of response and quality of life (QoL). Potential options include high-dose therapy with haematopoietic stem cell consolidation, non-myeloablative chemotherapy and whole-brain radiotherapy. Efficacy of novel agents, such as Bruton tyrosine kinase inhibitors and lenalidomide, have been reported; these represent an alternative for elderly patients unfit for chemotherapy. Prognosis remains poor, improvement of outcomes in this age group is urgently needed.

Diffuse large B-cell lymphoma in very elderly patients: Towards best tailored treatment - A systematic review

INTRODUCTION

Diffuse large B cell Lymphoma (DLBCL) is a potentially curative lymphoma with increasing incidence with ageing. Treatment of elderly DLBCL patients represents a particular challenge due to their comorbidities and performance status.

METHODS

A search for original articles focused on the treatment of elderly DLBCL patients was performed in PubMed database and 633 were found and reviewed. Thirty-eight studies meeting our inclusion criteria were published since 2007.

RESULTS

Thirteen studies were retrospective and 25 phase II/III clinical trials. Most of them investigated the efficacy of dose-adjusted R-CHOP regimen. Alternative therapeutic drugs together with geriatric assessment were also evaluated. For fit patients aged 80 and over, the strongest evidence favours R-miniCHOP regimen.

CONCLUSION

A dose-adjusted R-CHOP may be the recommended treatment in elderly DLBCL patients. New tools such as the Comprehensive Geriatric Assessment provide useful guidance for treatment choice, based on comorbidities and frailty index of this group.

Simplified Geriatric Assessment in Older Patients With Diffuse Large B-Cell Lymphoma: The Prospective Elderly Project of the Fondazione Italiana Linfomi

PURPOSE

To prospectively validate the use of a simplified geriatric assessment (sGA) at diagnosis and to integrate it into a prognostic score for older patients with diffuse large B-cell lymphoma (DLBCL).

METHODS

We conducted the prospective Elderly Project study on patients with DLBCL older than 64 years who underwent our Fondazione Italiana Linfomi original geriatric assessment (oGA) (age, Cumulative Illness Rating Scale for Geriatrics, activities of daily living, and instrumental activities of daily living) before treatment. Treatment choice was left to the physician's discretion. The primary end point was overall survival (OS) (ClinicalTrials.gov identifier: NCT02364050).

RESULTS

We analyzed 1,163 patients (median age 76 years), with a 3-year OS of 65% (95% CI, 62 to 68). Because at multivariate analysis on oGA, age > 80 years retained an independent correlation with OS, we also developed a new, simplified version of the GA (sGA) that classifies patients as fit (55%), unfit (28%), and frail (18%) with significantly different 3-year OS of 75%, 58%, and 43%, respectively. The sGA groups, International Prognostic Index, and hemoglobin levels were independent predictors of OS and were used to build the Elderly Prognostic Index (EPI). Three risk groups were identified: low (23%), intermediate (48%), and high (29%), with an estimated 3-year OS of 87% (95% CI, 81 to 91), 69% (95% CI, 63 to 73), and 42% (95% CI, 36 to 49), respectively. The EPI was validated using an independent external series of 328 cases.

CONCLUSION

The Elderly Project validates sGA as an objective tool to assess fitness status and defines the new EPI to predict OS of older patients with DLBCL.

Rituximab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in diffuse large B-cell lymphoma

Background

Diffuse large B-cell lymphoma (DLBCL) is the most frequent non-Hodgkin lymphoma worldwide. The current standard of care is chemoimmunotherapy with an R-CHOP regimen. We aim to review the role of this regimen after two decades of being the standard of care.

Methods

A comprehensive literature review of DLBCL, including the epidemiology, trials defining R-CHOP as the standard of care, as well as dose intensification and dose reduction schemes. Additionally, we briefly review the development of rituximab biosimilars and the addition of targeted drugs to R-CHOP in clinical trials.

Discussion

R-CHOP cures approximately 70% of DLBCL patients. Dose-dense regimens do not show a benefit in response and increase toxicity. Dose reduction, particularly in elderly patients or with comorbidities, may be a treatment option. DLBCL constitutes a group of diseases that activate different biological pathways. Matching specific treatments to a defined genetic alteration is under development. Rituximab biosimilars have become available to a broader population, particularly in developing countries, where access to treatment is limited because of economic resources.

Conclusion

DLBCL landscape is heterogeneous. R-CHOP immunochemotherapy has been a standard of care for two decades and cures approximately 70% of cases. Molecular characterization of patients is evolving and may have critical therapeutic implications.

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.

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.

Application of comprehensive geriatric assessment in predicting early mortality among elder patients with B-cell lymphoma receiving immunochemotherapy

OBJECTIVES

Early mortality, defined as death within 120 days after initiated antitumor therapy, is an important issue especially for elder patients with B-cell lymphoma. This study aimed to evaluate the clinical value of comprehensive geriatric assessment (CGA) in early mortality prediction in elderly patients with B-cell lymphoma receiving immunochemotherapy.

METHODS

Seventy-six consecutive patients with newly diagnosed B-cell lymphoma receiving immunochemotherapy from a medical center in Taiwan were prospectively enrolled. Patients were divided into fit (n = 49) and frail (n = 27) groups per pretreatment CGA for early mortality comparison.

RESULTS

The early mortality rate in our patient cohort was 16% (n = 12): from 6% in patients with no CGA domain impairment to 43% in patients with ≥4 CGA domain impairment. The early mortality rate was 6% and 33% in fit and frail patients (odds ratio, 7.67; 95% CI, 1.86-31.6; P = .005), respectively. Frailty was the significant predictor for early mortality in univariate and multivariate analysis.

CONCLUSION

In this study, the number of geriatric domain impairment is positively associated with the early mortality risk in elderly patients with B-cell lymphoma. Therefore, CGA can help clinicians to identify the risk of early mortality in elderly patients and provide alternative treatment.

Comprehensive Geriatric Assessment (CGA): A Simple Tool for Guiding the Treatment of Older Adults with Diffuse Large B-Cell Lymphoma in China

Background

We aimed to validate a simple Comprehensive Geriatric Assessment (CGA) in older adults with diffuse large B‐cell lymphoma (DLBCL) in China and to evaluate the tolerability and efficacy of CGA‐driven therapy.

Materials and Methods

In total, 78 patients with DLBCL aged ≥60 years were evaluated using CGA with the following parameters: age ≥ 80 years, activities of daily living (ADL), instrumental ADL, and modified cumulative illness rating score for geriatrics. Patients were grouped as fit, unfit, or frail. Patients classified as fit received standard‐dose rituximab plus CHOP, whereas patients in the latter two groups received reduced‐dose or reduced‐agent therapy. The overall response rate (ORR), overall survival (OS), progression‐free survival (PFS), and toxicities in the three groups were evaluated.

Results

According to the CGA, 45 (57.5%) patients were classified as fit, 5 (6.4%) as unfit, and 28 (35.9%) as frail. The ORR was 82.1% (64/78) among all the patients, including 55 patients (70.6%) who achieved complete response and 9 patients (11.5%) who achieved partial response. In the fit and unfit + frail groups, it achieved 97.8% and 60.6%, respectively. In total, 26 (33.3%) patients (10/45 [22.2%] fit and 16/33 [48.5%] unfit + frail) showed disease progression or recurrence. The median follow‐up time was 18 months (range, 5–62). The 3‐year OS and PFS rates were 82% and 58%, respectively. There were no treatment‐related deaths.

Conclusion

A simple CGA in older adults with DLBCL may be an effective tool for guiding therapeutic strategies in China.

Implications for Practice

Diffuse large B‐cell lymphoma (DLBCL) is the most common malignant lymphoma in older adults. The simple tool, Comprehensive Geriatric Assessment (CGA), is proved to be an effective method to identify older adults with DLBCL who are suitable for standard‐dose R‐CHOP regimen therapy. This is the first prospective trial in China to evaluate the tolerability and efficacy of CGA‐driven therapy for older adults with DLBCL, and the result showed that this simple CGA may be an effective tool for guiding therapeutic strategies.

Clinicians should take into account geriatric assessment results when recommending chemotherapy. This article evaluates the tolerability and efficacy of Comprehensive Geriatric Assessment‐driven therapy in China.

Feasibility and Outcome of a Phase II Study of Intensive Induction Chemotherapy in 91 Elderly Patients with AML Evaluated Using a Simplified Multidimensional Geriatric Assessment

Introduction

We prospectively tested in a phase II study high-dose aracytin and idarubicin plus amifostine as induction regimen in 149 patients with acute myeloid leukaemia (AML) aged ≥ 60 years, evaluated by a simplified multidimensional geriatric assessment (MGA).

Methods

Ninety-one fully or partially fit patients (61%) were allocated to intensive chemotherapy and 58 (39%) frail patients to best supportive care (BSC). Intensively treated patients, showing early death and complete response (CR) rate respectively of 5.5% and 73.6%, received 61 consolidations, followed by autologous transplant (ASCT), stem cell transplantation (SCT) or gemtuzumab ozogamicin, depending on mobilization outcome and donor availability.

Results

The 8-year overall survival (OS) of these patients was 20.4%, with median duration of 11.4 months significantly superior to the 1.5 months of BSC arm (p < 0.001). Hyperleukocytosis and cytogenetics were predictors of survival with a relative risk of 1.8 in patients with poor karyotype without hyperleukocytosis (p = 0.02) and 3 in those with hyperleukocytosis (≥ 50,000/μl) (p = 0.002).

Conclusion

MGA allowed tailored post-consolidation in 53.8% of patients after high-dose aracytin induction, with long-term survival doubling that reported in the literature after standard-dose cytarabine regimens.

Trial Registration

The study was registered with the Umin Clinical Trial Registry (www.umin.ac.jp/ctr), number R000014052.

Remaining challenges in predicting patient outcomes for diffuse large B-cell lymphoma

Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma and is an aggressive malignancy with heterogeneous outcomes. Diverse methods for DLBCL outcomes assessment ranging from clinical to genomic have been developed with variable predictive and prognostic success.Areas covered: The authors provide an overview of the various methods currently used to estimate prognosis in DLBCL patients. Models incorporating cell of origin, genomic features, sociodemographic factors, treatment effectiveness measures, and machine learning are described.Expert opinion: The clinical and genetic heterogeneity of DLBCL presents distinct challenges in predicting response to therapy and overall prognosis. Successful integration of predictive and prognostic tools in clinical trials and in a standard clinical workflow for DLBCL will likely require a combination of methods incorporating clinical, sociodemographic, and molecular factors with the aid of machine learning and high-dimensional data analysis.

The Prognostic Impact of Dose-attenuated R-CHOP Therapy for Elderly Patients with Diffuse Large B-cell Lymphoma

Objective Although R-CHOP (rituximab, cyclophosphamide, vincristine, doxorubicin, and prednisone) is a standard therapy for diffuse large B-cell lymphoma (DLBCL), the optimal dose for elderly patients remains unclear. Methods and Patients We retrospectively verified our R-CHOP dose-attenuation system implemented from 2005 for DLBCL patients. Among the 115 DLBCL patients treated during 2001-2010, 33 patients treated during 2001-2005 received R-CHOP doses adjusted according to physicians' decisions (PHY group). Eighty-two patients treated after 2005 received adjusted R-CHOP doses according to a unified dose-attenuation system (UNI group). Patients aged <60, 60-69, 70-79, and ≥80 years received the standard R-CHOP, 100% R-CHO+P (50 mg/m²), 100% R+75% CHO+P (40 mg/m²), and 100% R+50% CHO+P (30 mg/m²), respectively. We compared the responses, survival, and treatment cessation between the PHY and UNI groups. Results The patients' characteristics between both groups were closely comparable. All PHY patients received randomly adjusted R-CHOP doses; 94% of UNI patients received scheduled doses. The complete response rates differed significantly between the UNI (77%) and PHY patients (50%) (p=0.011). The two-year event-free survival rates were 50% and 32% in the UNI and PHY groups, respectively (p=0.0083). The two-year OS rates were 77% and 72% in the UNI and PHY group (p=0.16). Among the patients aged >70 years (n=59) overall survival was shorter in the PHY group (62%) than in the UNI group (72%; p=0.02). The UNI group received higher anti-tumor agent doses than the PHY group. The therapy discontinuation rates were 5% in the UNI group and 24% in the PHY group. Conclusion Carrying out unified dose reduction may improve the efficacy and prognosis among elderly DLBCL patients.

Adjusted Chemotherapy According to Frailty Status in Elderly Patients With Diffuse Large B-Cell Lymphoma: Experience From a Single Referral Center in Mexico City

BACKGROUND

Chemotherapy is associated with significant toxicity in elderly patients treated for hematological malignancies. Adequate tools to identify the best tailored treatment are essential.

PATIENTS AND METHODS

Medical charts of patients treated with adjusted chemotherapy for diffuse large B-cell lymphoma according to frailty status between August 1, 2013 and June 30, 2016 were included. Three groups were identified: fit, unfit, and frail patients.

RESULTS

Fifty-six patients with a median age of 70.5 years were analyzed. Adverse prognostic characteristics were more frequent than expected in the frail group, contributing to a worse outcome. The complete response (CR) rate for all patients was 61.2% (66.6%, 78.3%, and 40.0% for fit, unfit, and frail patients, respectively; P = .121). The 2-year overall survival (OS) for all patients was 78% (87%, 82%, and 59% for fit, unfit, and frail patients, respectively; P = .159) and the mean 2-year disease-free survival was 96% (87% for frail patients and 100% for unfit and fit patients; P = .287). Grade 3/4 hematologic toxicity was present in 83.3%, 65.2%, and 45% of fit, unfit, and frail patients, respectively. CR after therapy had a positive effect on OS, whereas ≥ 2 extranodal sites and febrile neutropenia had a negative effect.

CONCLUSION

Frailty status assessment resulted in the identification of a group of unfit patients who had adequate tolerance to adjusted chemotherapy (R-choP; rituximab with cyclophosphamide, doxorubicin, and vincristine adjusted to 80% of the corresponding total doses in R-CHOP [rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone]) with good results.

Frailty status but not age predicts complications in elderly cancer patients: a follow-up study

OBJECTIVES

The purposes were to investigate the health status of elderly cancer patients by comprehensive geriatric assessment (CGA) and to compare the complications with respect to baseline CGA and to evaluate the need for geriatric interventions in an elderly cancer patients' population.

MATERIAL

Patients aged ≥70 years with lung cancer (LC), cancer of the head and neck (HNC), colorectal cancer (CRC), or upper gastro-intestinal cancer (UGIC) are referred to the Department of Oncology for cancer treatment.

METHODS

CGA was performed prior to cancer treatment and addressed the following domains: Activities of daily living (ADL), instrumental ADL (IADL), comorbidity, polypharmacy, nutrition, cognition, and depression. Complications, defined as dose reduction and discontinuation of treatment due to grade 3-4 toxicity, hospital admission, shift to palliative treatment, or death within 90 days, were identified from the medical files. Patients were classified as fit, vulnerable, or frail by CGA.

PRINCIPAL RESULTS

Patients (N = 217) with a median age of 75 years (range: 70-93 yeas) were included: 13% were fit, 35% vulnerable, and 52% frail. CGA significantly predicted admittance to hospital in frail and vulnerable patients compared to fit patients: risk ratio (RR) 2.12 (95% CI: 1.01; 4.46). Vulnerable and frail patients had higher absolute risk of death within 90 days compared to fit patients: 7% and 23% versus 0%. HR for death within 90 days in frail patients as compared to vulnerable patients was 3.50 (95% CI: 1.34; 9.15). More frail patients (88%) needed geriatric interventions than the vulnerable (46%) and fit patients (32%). Major conclusion: Few elderly cancer patients seem to be fit. CGA predicts admittance to hospital in a population of elderly patients with mixed cancer diseases. Frail and vulnerable patients have higher risk of death within 90 days as compared to fit patients.

Role of anthracycline and comprehensive geriatric assessment for elderly patients with diffuse large B-cell lymphoma

Survival outcome for elderly patients with newly diagnosed diffuse large B-cell lymphoma remains suboptimal in the rituximab era. In this systematic review, we summarize available evidence relevant to the inclusion of anthracycline in upfront chemoimmunotherapy for these elderly patients and highlight the need of prospective clinical trials. With limited prospective data, we find that pretreatment comprehensive geriatric assessment accurately predicts survival and treatment-related toxicities, suggesting its potential role in guiding overall treatment decision-making.

Modern Management of Anthracycline-Induced Cardiotoxicity in Lymphoma Patients: Low Occurrence of Cardiotoxicity with Comprehensive Assessment and Tailored Substitution by Nonpegylated Liposomal Doxorubicin

BACKGROUND

Anthracyclines (AC) are still undeniable drugs in lymphoma treatment, despite occasionally causing cardiotoxicity. Liposomal AC may reduce cardiotoxicity while retaining clinical efficacy; also, biomarker monitoring during chemotherapy allows early detection of cardiac damage, enabling strategies to prevent left ventricular ejection fraction (LVEF) deterioration.

MATERIALS AND METHODS

We conducted a prospective observational trial in a real-life population of lymphoma patients, combining advanced echocardiography and biomarkers (Troponin I [TnI]) for early detection of cardiotoxicity; we applied a prespecified policy to minimize cardiotoxicity, selecting patients with higher baseline risk to replace doxorubicin with nonpegylated liposomal doxorubicin (NPLD) and starting cardioprotective treatment when subclinical cardiotoxicity was detected.

RESULTS

Ninety-nine patients received ≥1 cycle of chemotherapy (39 with NPLD): 38 (NPLD = 34) were older than 65 years. At baseline, the NPLD subgroup had more cardiovascular risk factors and comorbidities than the doxorubicin subgroup. After treatment, echocardiographic parameters did not worsen in the NPLD subgroup; significant LVEF reduction occurred in two patients treated with doxorubicin. Over treatment course, TnI rises increased linearly in the doxorubicin subgroup but modestly in the NPLD subgroup. At doxorubicin doses >200 mg/m² the difference was statistically significant, with more TnI rises in the doxorubicin subgroup. NPLD-treated patients did not experience higher rates of grade 3-4 adverse events. Within the diffuse large B-cell lymphomas category, we observed similar rates of complete and overall responses between doxorubicin- and NPLD-treated patients.

CONCLUSION

A comprehensive strategy to prevent, detect, and treat cardiotoxicity allows an optimal management of the lymphoma with low incidence of cardiac complications. The Oncologist 2017;22:422-431 IMPLICATIONS FOR PRACTICE: Despite the recent advances of targeted therapy in cancer, old cytotoxic drugs such as anthracyclines (AC) still play a fundamental role in the treatment of many lymphoma patients. We tested and validated in a real-life setting a personalized approach to prevent, detect, and treat AC-induced cardiotoxicity; biomarker monitoring was accomplished by Troponin I measurements before and after chemotherapy infusions, allowing detection of early subclinical cardiotoxicity, which was preemptively treated with cardio-protectants (beta blockers and angiotensin-converting-enzyme inhibitors). A telemedicine system allowed interdisciplinary management of the patients with an expert cardiologist. Furthermore, tailored use of liposomal AC following a prespecified policy appeared to prevent the excess cardiotoxicity expected in high-risk patients.

Comparison of Three Chemotherapy Regimens in Elderly Patients with Diffuse Large B Cell Lymphoma: Experience at a Single National Reference Center in Mexico

Background. Although chemotherapy added to rituximab is a standard of care for diffuse large B cell lymphoma (DLBCL), treatment of patients ≥65 years of age remains controversial due to comorbidities. Methods. This is a retrospective, comparative, nonrandomized study of patients ≥65 years of age, who were diagnosed with DLBCL but not previously treated. Demographic characteristics and comorbidities were analyzed. Three rituximab-containing treatment regimens (standard RCHOP, anthracycline dose-reduced RChOP, and RCOP) were compared. Descriptive analyses were conducted. Survival was calculated with the Kaplan-Meier method, and differences were compared with the log-rank test. Results. In total, 141 patients with a median age of 73.9 years were studied. The three treatment groups had comparable demographic characteristics. The overall response was 77%, 72.5%, and 59% in groups treated with RCHOP, RChOP, and RCOP, respectively. After multivariate analysis, the factors influencing the overall survival were the presence of B symptoms, poor performance status (ECOG ≥ 3), and febrile neutropenia. Factors influencing disease-free survival were febrile neutropenia, high-intermediate and high-risk IPI scores, and treatment without anthracycline. Conclusion. A higher ORR (overall response rate) was achieved with standard RCHOP, which influenced DFS and OS, although it was not statistically significant compared with the other groups. Interventional phase 3 trials testing new molecules in patients aged 70 to 80 years and older are required to improve the prognosis within this growing population.

Analysis of elderly patients with diffuse large B-cell lymphoma: aggressive therapy is a reasonable approach for 'unfit' patients classified by comprehensive geriatric assessment

BACKGROUND

The treatment strategy for diffuse large B-cell lymphoma (DLBCL) in elderly patients is problematic. Although several researchers have reported the effectiveness of comprehensive geriatric assessment (CGA) and the futility of curative treatment in 'unfit' patients with DLBCL, these propositions are not firmly established.

PATIENTS AND METHODS

We conducted a retrospective analysis using a database. Patients with DLBCL were eligible if ≧ 60 yr old. CGA stratification was performed using medical records.

RESULTS

One hundred and 35 patients were identified. Anthracycline-based chemotherapy with curative intent was performed in 115 (85%) patients. According to CGA, 82 (61%) patients were classified as 'fit'. Their 1-yr overall survival (OS) was significantly better than that of 'unfit' patients [91.3% vs. 53.8%, P < 0.001]. Patients classified as 'unfit' treated with curative intent had a significantly better 1-yr OS when compared with those receiving palliative measures [66.1% vs. 19.0%, P < 0.001].

CONCLUSIONS

CGA is an effective tool for predicting outcomes in older patients with DLBCL. The patients treated with curative intent had significantly better outcomes compared with those receiving palliation, irrespective of CGA stratification. Curative treatment should be considered even for 'unfit' patients.

Trends in incidence, treatment and survival of aggressive B-cell lymphoma in the Netherlands 1989-2010

Only a small number of patients with aggressive B-cell lymphoma take part in clinical trials, and elderly patients in particular are under-represented. Therefore, we studied data of the population-based nationwide Netherlands Cancer Registry to determine trends in incidence, treatment and survival in an unselected patient population. We included all patients aged 15 years and older with newly diagnosed diffuse large B-cell lymphoma or Burkitt lymphoma in the period 1989-2010 and mantle cell lymphoma in the period 2001-2010, with follow up until February 2013. We examined incidence, first-line treatment and survival. We calculated annual percentage of change in incidence and carried out relative survival analyses. Incidence remained stable for diffuse large B-cell lymphoma (n=23,527), while for mantle cell lymphoma (n=1,634) and Burkitt lymphoma (n=724) incidence increased for men and remained stable for women. No increase in survival for patients with aggressive B-cell lymphoma was observed during the period 1989-1993 and the period 1994-1998 [5-year relative survival 42% (95%CI: 39%-45%) and 41% (38%-44%), respectively], but increased to 46% (43%-48%) in the period 1999-2004 and to 58% (56%-61%) in the period 2005-2010. The increase in survival was most prominent in patients under 65 years of age, while there was a smaller increase in patients over 75 years of age. However, when untreated patients were excluded, patients over 75 years of age had a similar increase in survival to younger patients. In the Netherlands, survival for patients with aggressive B-cell lymphoma increased over time, particularly in younger patients, but also in elderly patients when treatment had been initiated. The improvement in survival coincided with the introduction of rituximab therapy and stem cell transplantation into clinical practice.

International Society of Geriatric Oncology consensus on geriatric assessment in older patients with cancer

PURPOSE

To update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on geriatric assessment (GA) in older patients with cancer.

METHODS

SIOG composed a panel with expertise in geriatric oncology to develop consensus statements after literature review of key evidence on the following topics: rationale for performing GA; findings from a GA performed in geriatric oncology patients; ability of GA to predict oncology treatment–related complications; association between GA findings and overall survival (OS); impact of GA findings on oncology treatment decisions; composition of a GA, including domains and tools; and methods for implementing GA in clinical care.

RESULTS

GA can be valuable in oncology practice for following reasons: detection of impairment not identified in routine history or physical examination, ability to predict severe treatment-related toxicity, ability to predict OS in a variety of tumors and treatment settings, and ability to influence treatment choice and intensity. The panel recommended that the following domains be evaluated in a GA: functional status, comorbidity, cognition, mental health status, fatigue, social status and support, nutrition, and presence of geriatric syndromes. Although several combinations of tools and various models are available for implementation of GA in oncology practice, the expert panel could not endorse one over another.

CONCLUSION

There is mounting data regarding the utility of GA in oncology practice; however, additional research is needed to continue to strengthen the evidence base.

An update on a systematic review of the use of geriatric assessment for older adults in oncology

BACKGROUND

Our previous systematic review of geriatric assessment (GA) in oncology included a literature search up to November 2010. However, the quickly evolving field warranted an update. Aims of this review: (i) provide an overview of all GA instruments developed and/or in use in the oncology setting; (ii) evaluate effectiveness of GA in predicting/modifying outcomes (e.g. treatment decision impact, treatment toxicity, mortality, use of care).

MATERIALS AND METHODS

Systematic review of literature published between November 2010 and 10 August 2012. English, Dutch, French and German-language articles reporting cross-sectional or longitudinal, intervention or observational studies of GA instruments were included.

DATA SOURCES

MEDLINE, EMBASE, PsycINFO, CINAHL and Cochrane Library. Two researchers independently reviewed abstracts, abstracted data and assessed the quality using standardized forms. A meta-analysis method of combining proportions was used for the outcome impact of GA on treatment modification with studies included in this update combined with those included in our previous systematic review on the use of GA.

RESULTS

Thirty-five manuscripts reporting 34 studies were identified. Quality of most studies was moderate to good. Eighteen studies were prospective, 11 cross-sectional and 5 retrospective. Three studies examined treatment decision-making impact and found decisions changed for fewer than half of assessed patients (weighted percent modification is 23.2% with 95% confidence interval (20.3% to 26.1%). Seven studies reported conflicting findings regarding predictive ability of GA for treatment toxicity/complications. Eleven studies examined GA predictions of mortality, and reported that instrumental activities of daily living, poor performance status and more numerous GA deficits were associated with increased mortality risk. Other outcomes could not be meta-analyzed.

CONCLUSION

Consistent with our previous review, several domains of GA are associated with adverse outcomes. However, further research examining effectiveness of GA on treatment decisions and oncologic outcomes is needed.
