Oncologist Perceptions of Racial Disparity, Racial Anxiety, and Unconscious Bias in Clinical Interactions, Treatment, and Outcomes.

BACKGROUND: Cancer spares no demographic or socioeconomic group; it is indeed the great equalizer. But its distribution is not equal; when structural discrimination concentrates poverty and race, zip code surpasses genetic code in predicting outcomes. Compared with White patients in the United States, Black patients are less likely to receive appropriate treatment and referral to clinical trials, genetic testing, or palliative care/hospice. METHODS: In 2021, we administered a survey to 369 oncologists measuring differences in perceptions surrounding racial disparity, racial anxiety, and unconscious bias and adverse influence on clinical interactions, treatment, and outcomes for non-White patients. We analyzed responses by generational age group, sex/gender, race/ethnicity, US region, and selection of "decline to respond." RESULTS: The most significant differences occurred by age group followed by race/ethnicity. Racial disparity was perceived as moderate to very high by 84% of millennial, 69% of Generation X, and 57% of baby boomer oncologists, who were also 86% more likely than millennials and 63% more likely than Generation Xers to perceive low/nonexistent levels of racial anxiety/unconscious bias. CONCLUSIONS: Most oncologists rarely or never perceived racial anxiety/unconscious bias as adversely influencing clinical treatment or survival outcomes in non-White patients, and White oncologists were 85% more likely than non-White oncologists to perceive rare/nonexistent influence on referral of non-White patients to palliative care/hospice. The discrepancy between 62% of oncologists perceiving moderate to very high levels of racial anxiety/unconscious bias and 37% associating them with adverse influence on non-White patients shows a disconnect, especially among older oncologists (baby boomers), who were also least likely to select the decline option. Together, these factors hinder effective patient-provider communication and result in differential care and outcomes. Oncologists should uncover their own perceptions surrounding racial disparity, racial anxiety, and unconscious bias and modify their behaviors accordingly. It is this simple-and this complicated. Cancer does not discriminate, and neither should cancer care.

Characteristics, Treatment, and Outcomes of Real-World Talazoparib-Treated Patients With Germline BRCA-Mutated Advanced HER2-Negative Breast Cancer.

BACKGROUND: Talazoparib is a poly (adenosine diphosphate-ribose) polymerase inhibitor approved for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), HER2-negative, locally advanced or metastatic breast cancer (LA/mBC), with approval based on the EMBRACA trial. To date, there are no published data on talazoparib use in the real-world United States (USA) setting. PATIENTS AND METHODS: Characteristics, treatment patterns, and clinical outcomes of real-world US patients with gBRCAm HER2-negative LA/mBC treated with talazoparib monotherapy were collected via retrospective chart review and summarized using descriptive statistics. RESULTS: Among 84 eligible patients, 35.7% had hormone receptor-positive tumors and 64.3% had triple-negative LA/mBC (TNBC). At talazoparib initiation, 29.8% had ECOG PS of ≥2 and 19.0% had brain metastasis. Mutations in gBRCA1 or 2 were detected among 64.3% and 35.7% of patients, respectively. Talazoparib was given as 1st-line therapy in 14.3% of patients, 2nd-line in 40.5%, and 3rd- or 4th-line in 45.2%. Median time to talazoparib treatment failure was 8.5 months (95% CI, 8.0-9.7), median progression-free survival was 8.7 months (95% CI, 8.0-9.9), the median time from initiation to chemotherapy was 12.2 months (95% CI, 10.5-20.1), and the overall response rate was 63.1%. No differences in clinical outcomes were observed between patients with HR-positive/HER2-negative LA/mBC and patients with TNBC by using unadjusted statistical comparisons. Brain metastasis and ECOG PS ≥2 at talazoparib initiation were associated with treatment failure and progression or mortality. CONCLUSION: Overall, talazoparib clinical outcomes in this real-world population are consistent with findings from EMBRACA.

Risk Factors for Hospitalizations Among Older Adults with Gastrointestinal Cancers.

BACKGROUND: Older adults (≥65 years) with gastrointestinal (GI) cancers who receive chemotherapy are at increased risk of hospitalization caused by treatment-related toxicity. Geriatric assessment (GA) has been previously shown to predict risk of toxicity in older adults undergoing chemotherapy. However, studies incorporating the GA specifically in older adults with GI cancers have been limited. This study sought to identify GA-based risk factors for chemotherapy toxicity-related hospitalization among older adults with GI cancers. PATIENTS AND METHODS: We performed a secondary post hoc subgroup analysis of two prospective studies used to develop and validate a GA-based chemotherapy toxicity score. The incidence of unplanned hospitalizations during the course of chemotherapy treatment was determined. RESULTS: This analysis included 199 patients aged ≥65 years with a diagnosis of GI cancer (85 colorectal, 51 gastric/esophageal, and 63 pancreatic/hepatobiliary). Sixty-five (32.7%) patients had ≥1 hospitalization. Univariate analysis identified sex (female), cardiac comorbidity, stage IV disease, low serum albumin, cancer type (gastric/esophageal), hearing deficits, and polypharmacy as risk factors for hospitalization. Multivariable analyses found that patients who had cardiac comorbidity (OR 2.48, 95% CI 1.13-5.42) were significantly more likely to be hospitalized. CONCLUSION: Cardiac comorbidity may be a risk factor for hospitalization in older adults with GI cancers receiving chemotherapy. Further studies with larger sample sizes are warranted to examine the relationship between GA measures and hospitalization in this vulnerable population.

Older Patients with Lung Cancer: a Summary of Seminal Contributions to Optimal Patient Care.

PURPOSE OF REVIEW: This review aspires to summarize the landmark advancements in the management of the non-small cell lung cancer (NSCLC), both historically and contemporarily with special focus in older adults. RECENT FINDINGS: The past two decades have witnessed remarkable improvements in the diagnosis and management of lung cancer. Screening recommendations now facilitate earlier diagnosis in high-risk individuals, PET/CT scans have improved radiologic accuracy in identifying sites of disease, and surgical management with minimally invasive techniques has rendered surgery safer in those with limited physiologic reserve. Radiation enhancements, especially radiosurgery, have extended the reach and safety of radiation among high-risk populations. Finally, the revolution in precision medicine with identification of numerous actionable mutations, the advent of immunotherapy, and enhanced supportive care have revolutionized the outcomes in patients with advanced lung cancer. Older adults who represent a majority of patients battling lung cancer have not benefitted to the same extent as their younger counterparts. This special population is only expected to grow in coming days. Hence, addressing major gaps in the management of older adults with NSCLC and optimizing the care are much needed.

Augmented intelligence to predict 30-day mortality in patients with cancer.

Aim: An augmented intelligence tool to predict short-term mortality risk among patients with cancer could help identify those in need of actionable interventions or palliative care services. Patients & methods: An algorithm to predict 30-day mortality risk was developed using socioeconomic and clinical data from patients in a large community hematology/oncology practice. Patients were scored weekly; algorithm performance was assessed using dates of death in patients' electronic health records. Results: For patients scored as highest risk for 30-day mortality, the event rate was 4.9% (vs 0.7% in patients scored as low risk; a 7.4-times greater risk). Conclusion: The development and validation of a decision tool to accurately identify patients with cancer who are at risk for short-term mortality is feasible.

Associations between nutritional factors and chemotherapy toxicity in older adults with solid tumors.

BACKGROUND: Nutritional status can directly affect morbidity and mortality in older adults with cancer. This study evaluated the association between pretreatment body mass index (BMI), albumin level, and unintentional weight loss (UWL) in the prior 6 months and chemotherapy toxicity among older adults with solid tumors. METHODS: This was a secondary analysis of a prospective, multicenter study involving chemotherapy-treated patients 65 years old or older. Geriatric assessment, BMI, albumin level, and UWL data were collected before treatment. Multivariable logistic regression models evaluated the associations between nutritional factors and the risk of grade 3 or higher (grade 3+) chemotherapy toxicity. RESULTS: Seven hundred fifty patients with a median age of 72 years (range, 65-94 years) and mostly stage IV disease were enrolled. The median pretreatment BMI and albumin values were 26 kg/m2 (range, 15.1-52.1 kg/m2 ) and 3.9 mg/dL (range, 1.0-5.0 mg/dL), respectively. Nearly 50% of the patients reported UWL, with 17.6% reporting >10% UWL. Multivariable analysis revealed no association between >10% UWL and a risk for grade 3+ chemotherapy toxicity (adjusted odds ratio [AOR], 0.87; P = .58). Multivariable analysis showed a trend toward an association between a BMI ≥ 30 kg/m2 and a decreased risk of grade 3+ chemotherapy toxicity (AOR, 0.65; P = .06), whereas a low albumin level (≤3.6 mg/dL) was associated with a higher risk of grade 3+ chemotherapy toxicity (AOR, 1.50; P = .03). An analysis of the joint effect of BMI and albumin demonstrated the lowest risk of grade 3+ chemotherapy toxicity among patients with high BMIs (≥30 kg/m2 ) and normal albumin levels (AOR, 0.41; P = .008). CONCLUSIONS: Among older adults with solid tumors, higher BMIs and normal albumin levels are associated with a lower risk of grade 3+ chemotherapy toxicity. Additional research is warranted to define the clinical significance of nutritional markers and to inform future interventions.

Comparative Effectiveness of Palliative Chemotherapy in Metastatic Breast Cancer: A Real-World Evidence Analysis.

BACKGROUND: In the absence of randomized controlled trials, real-world evidence may aid practitioners in optimizing the selection of therapy for patients with cancer. The study's aim was to determine real-word use, as well as compare effectiveness, of single-agent and combination chemotherapy as palliative treatment for female patients with metastatic breast cancer (mBC). MATERIALS AND METHODS: Using administrative claims data from the Symphony Health's Integrated Oncology Dataverse, female patients with mBC treated with at least one chemotherapy-only treatment (COT) between January 1, 2013, and December 31, 2017 were selected. The frequency of use of single-agent versus combination chemotherapy overall and by line of therapy (LOT) was calculated whereas effectiveness was measured using time to next treatment (TNT). RESULTS: A total of 12,381 patients with mBC were identified, and 3,777 (31%) received at least one line of COT. Of the 5,586 observed LOTs among the 3,777 patients, 66.5% were single-agent and 33.5% combination chemotherapy. Combination chemotherapy was most frequently used in first-line (45%) and least frequently in fifth-line (16%). Across all LOTs, median TNT was significantly longer for single-agent versus combination chemotherapy (5.3 months vs. 4.1 months, p < .0001). Comparison of median TNT by LOT showed significance in third-line and greater but not in first-line or second-line. Among single agents, the median TNT for patients receiving capecitabine was longest in comparison to all other single agents. CONCLUSIONS: The frequency of combination COT use, particularly in first-line, warrants further research given published guideline recommendations. The observed TNT difference favoring single-agent treatment in later lines supports guideline recommendations. Variance between single-agent preference and observed TNT was noteworthy. IMPLICATIONS FOR PRACTICE: Although published data from evidence- and consensus-based guidelines recommend single-agent over combination chemotherapy, the extensive list of agents available for use and a gap in the comparative effectiveness research of these agents have resulted in significant variances in patterns of care. The aim of this study was to assess real-world treatment patterns and their effectiveness during palliative therapy of metastatic breast cancer. The objective was to understand when and how chemotherapy-only treatment is used in metastatic breast cancer and whether comparative effectiveness analysis supports the observed patterns of care.

Identifying Geriatric Oncology Competencies for Medical Oncology Trainees: A Modified Delphi Consensus Study.

BACKGROUND: Most oncology trainees are not taught about the needs of older patients, who make up the majority of patients with cancer. Training of health care providers is critical to improve the care of older adults with cancer. There is no consensus about which geriatric oncology (GO) competencies are important for medical oncology trainees. Our objective was to identify GO competencies medical oncology trainees should acquire during training. MATERIALS AND METHODS: A modified Delphi consensus of experts in oncology medical education and GO was conducted. Experts categorized at what training stage proposed competencies should be attained: internal medicine, oncology, or GO training. Consensus was obtained if two thirds of experts agreed on the training stage at which the competency should be attained. RESULTS: A total of 78 potential competencies were identified, of which 35 (44.9%) proposed competencies were felt to be appropriate to be acquired during oncology training. The majority of the identified competencies pertained to prescribing of systemic therapy (n = 12) and psychosocial and supportive care (n = 13). No competencies related to geriatric assessment were identified for acquisition during oncology training. CONCLUSION: Experts in oncology education and geriatric oncology agreed upon a set of GO competencies appropriate for oncology trainees. These results provide the foundation for developing a GO curriculum for medical oncology trainees and will hopefully lead to better care of older adults with cancer. IMPLICATIONS FOR PRACTICE: The aging population will drive the projected rise in cancer incidence. Although aging patients make up the majority of patients diagnosed with cancer, oncologists rarely receive training on how to care for them. Training of health care providers is critical to improving the care of older adults with cancer. The results of this study will help form the foundation of developing a geriatric oncology curriculum for medical oncology trainees.

Use of Real-World Evidence to Support FDA Approval of Oncology Drugs.

OBJECTIVES: Real-world evidence (RWE) has gained increased attention in recent years as a complement to traditional clinical trials. The use of RWE to establish the efficacy of oncology drugs for Food and Drug Administration (FDA) approval has not been described. In this paper, we review 5 recent examples where RWE was submitted in support of the FDA approvals of original or supplementary indications for oncology drugs. METHODS: To identify cases where RWE was used, we reviewed drug approval packages available at Drugs@FDA for oncology drugs approved between 2017 and 2019. Five cases were selected to present a broad overview of different types of RWE, different circumstances under which RWE has been used for regulatory approvals, and how FDA evaluated the data in each case. The type of RWE submitted, the indication, limitations identified by FDA reviewers, and the outcome of the submission are discussed. RESULTS: RWE, particularly historical controls for rare or orphan indications, has been used to support both original and supplementary oncology drug approvals. Types of RWE included data from electronic health records, claims, post-marketing safety reports, retrospective medical record reviews, and expanded access studies. Small sample sizes, data quality, and methodological issues were among concerns cited by FDA reviewers. CONCLUSION: By bridging the gap between the constraints of the trial setting and the realities of clinical practice, RWE can add value to a regulatory submission. These early examples provide insight into how regulators evaluated RWE submitted as evidence of efficacy for oncology drugs.

Physician treatment of metastatic triple-negative breast cancer in the immuno-oncology era: a discrete choice experiment.

Aim: Guidelines list atezolizumab with nab-paclitaxel (ANP) as the preferred first-line (1L) therapy for metastatic triple-negative breast cancer (mTNBC) with PD-L1 expression ≥1%, but which clinical attributes impact ANP prescribing? Materials & methods: Medical oncologists participated in a discrete choice experiment (DCE) with four hypothetical mTNBC clinical scenarios to assess influences of: PD-L1 expression, menopausal status, prior adjuvant therapy and bulky liver metastases. Results: A total of 47% chose ANP in 1L irrespective of menopausal status, prior adjuvant therapy or tumor bulk. PD-L1 expression was the only attribute with a significant impact on ANP preference, with 69% choosing ANP for those with ≥1% expression versus only 26% for those with <1% (p < 0.00001). Conclusion: ANP choice for 1L mTNBC deviated from guidelines.

Real-world incidence and cost of pneumonitis post-chemoradiotherapy for Stage III non-small-cell lung cancer.

Aim: To estimate the real-world incidence and timing of radiation pneumonitis following chemoradiotherapy for Stage III non-small-cell lung cancer and compare costs between patients with and without radiation pneumonitis. Methods: Retrospective analysis using the Symphony Health Integrated Dataverse. Results: Pneumonitis incidence was 12.4% with a 177-day mean time to onset. Patients with versus without pneumonitis were more frequently admitted to the hospital (33.8 vs 19.2%, p < 0.0001) and seen in the emergency room (51.9 vs 35.8%, p < 0.0001) and had higher mean total healthcare costs (US$4251 vs US$3969 per-patient per-month; p = 0.0163). Conclusion: Although pneumonitis significantly increased healthcare resource utilization and costs in chemoradiotherapy-treated Stage III non-small-cell lung cancer, the per-patient per-month differential was <10%. Such financial assessments are critical for cost-benefit analysis.

Association between patient-reported hearing and visual impairments and functional, psychological, and cognitive status among older adults with cancer.

BACKGROUND: Hearing and visual impairments are common among community-dwelling older adults, and are associated with psychological, functional, and cognitive deficits. However, to the authors' knowledge, little is known regarding their prevalence among older patients with cancer. METHODS: The current study was a secondary analysis combining 2 prospective cohorts of adults aged ≥65 years with solid tumors who were receiving chemotherapy. The authors assessed the association between patient-reported hearing and/or visual impairment (defined as fair/poor grading by self-report) and physical function, instrumental activities of daily living (IADLs), anxiety, depression, and cognition. Descriptive analyses were conducted to summarize patient and treatment characteristics. One-way analysis of variance and chi-square tests were conducted as appropriate to examine differences between patients with and without sensory impairments. Logistic regression was used to analyze associations between sensory impairments and outcomes. RESULTS: Among 750 patients with a median age of 72 years who had solid tumors (29% with breast/gynecological tumors, 28% with lung tumors, and 27% with gastrointestinal tumors), approximately 18% reported hearing impairment alone, 11% reported visual impairment alone, and 7% reported dual sensory impairment. Hearing impairment was associated with IADL dependence (odds ratio [OR], 1.9), depression (OR, 1.6), and anxiety (OR, 1.6). Visual impairment was associated with IADL dependence (OR, 1.9), poor physical function (OR, 1.9), and depression (OR, 2.5). Dual impairment was associated with IADL dependence (OR, 2.8), anxiety (OR, 2.3), depression (OR, 2.5), and cognitive impairment (OR, 3.2). CONCLUSIONS: Sensory impairment is common among older adults with cancer. Patients with sensory impairment are more likely to have functional, psychological, and cognitive deficits. Interventions aimed at improving the vision and hearing of older adults with cancer should be studied. Cancer 2018. © 2018 American Cancer Society.

Factors associated with falls in older adults with cancer: a validated model from the Cancer and Aging Research Group.

BACKGROUND: Falls in older adults with cancer are common, yet factors associated with fall-risk are not well-defined and may differ from the general geriatric population. This study aims to develop and validate a model of factors associated with prior falls among older adults with cancer. METHODS: In this cross-sectional secondary analysis, two cohorts of patients aged ≥ 65 with cancer were examined to develop and validate a model of factors associated with falls in the prior 6 months. Potential independent variables, including demographic and laboratory data and a geriatric assessment (encompassing comorbidities, functional status, physical performance, medications, and psychosocial status), were identified. A multivariate model was developed in the derivation cohort using an exhaustive modeling approach. The model selected for validation offered a low Akaike Information Criteria value and included dichotomized variables for ease of clinical use. This model was then applied in the validation cohort. RESULTS: The development cohort (N = 498) had a mean age of 73 (range 65-91). Nearly one-fifth (18.2%) reported a fall in the prior 6 months. The selected model comprised nine variables involving functional status, objective physical performance, depression, medications, and renal function. The AUC of the model was 0.72 (95% confidence intervals 0.65-0.78). In the validation cohort (N = 250), the prevalence of prior falls was 23.6%. The AUC of the model in the validation cohort was 0.62 (95% confidence intervals 0.51-0.71). CONCLUSION: In this study, we developed and validated a model of factors associated with prior falls in older adults with cancer. Future study is needed to examine the utility of such a model in prospectively predicting incident falls.

Comparative "nocebo effects" in older patients enrolled in cancer therapeutic trials: Observations from a 446-patient cohort.

BACKGROUND: A nocebo is an inert substance associated with adverse events. Although previous studies have examined the positive (placebo) effects of such inert substances, few have examined negative (nocebo) adverse event profiles, particularly in older patients who have higher morbidity and can experience frequent and severe adverse events from cancer therapy. METHODS: This study focused on placebo/nocebo-exposed patients who participated in 2 double-blind, placebo-controlled, cancer therapeutic studies, namely, North Central Cancer Therapy Group trial NCCTG 97-24-51 and American College of Surgeons Oncology Group trial Z9001, with the goal of reporting the comparative, age-based adverse event rates, as reported during the conduct of these trials. RESULTS: Among the 446 patients who received only placebo/nocebo and who were the focus of the current report, 161 were aged ≥65 years at the time of respective trial entry, and 5234 adverse events occurred. Unadjusted adverse event rates did not differ significantly between patients aged ≥65 years and younger patients (rate ratio, 1.01; 99% confidence interval, 0.47-2.02), and the findings were similar findings for grade 2 or worse adverse events and for all symptom-driven adverse events (for example, pain, loss of appetite, anxiety). Adjustment for sex, ethnicity, baseline performance score, and individual trial resulted in no significant age-based differences in adverse event rates. Similar findings were observed with an age threshold of 70 years. CONCLUSIONS: Adverse events are equally common in older and younger cancer patients who are exposed to nocebo and thus require the same degree of clinical consideration regardless of age.

Frailty as determined by a comprehensive geriatric assessment-derived deficit-accumulation index in older patients with cancer who receive chemotherapy.

BACKGROUND: Frailty has been suggested as a construct for oncologists to consider in treating older cancer patients. Therefore, the authors assessed the potential of creating a deficit-accumulation frailty index (DAFI) from a largely self-administered comprehensive geriatric assessment (CGA). METHODS: Five hundred patients aged ≥65 years underwent a CGA before receiving chemotherapy. A DAFI was constructed, resulting in a 51-item scale, and cutoff values were examined for patients in the robust/nonfrail (cutoff value, 0.0 < 0.2), prefrail (cutoff value, 0.2 < 0.35), and frail (cutoff value, ≥ 0.35) groups. RESULTS: Two hundred and fifty patients (50%) were nonfrail, 197 (39%) were prefrail, and 52 (11%) were frail. Older patients (aged ≥ 80 years) and those who had lower education, were living alone, and had higher stage disease were associated with prefrail/frail status. Prefrail/frail patients were more likely to have grade ≥3 toxicity but not to have a dose delay or reduction, and they were more likely to discontinue drug and be hospitalized. The association with grade ≥3 toxicity was attenuated by controlling for a toxicity risk calculator, but the other outcomes were not. CONCLUSIONS: A deficit-accumulation frailty index can be constructed from a CGA in older patients with cancer and can indicate the frailty status of the population. The frailty status so determined is associated both with outcomes likely because of chemotherapy toxicity and with those likely because of age-related physiologic and functional deficits and thus can be useful in the overall assessment of the patient.

Social support and its implications in older, early-stage breast cancer patients in CALGB 49907 (Alliance A171301).

BACKGROUND: Studies point to a direct association between social support and better cancer outcomes. This study examined whether baseline social support is associated with better survival and fewer chemotherapy-related adverse events in older, early-stage breast cancer patients. METHODS: This study is a pre-planned secondary analysis of CALGB 49907/Alliance A171301, a randomized trial that compared standard adjuvant chemotherapy versus capecitabine in breast cancer patients 65 years of age or older. A subset reported on the extent of their social support with questionnaires that were completed 6 times over 2 years. RESULTS: The median age of this 331-patient cohort was 72 years (range: 65, 90); 179 (55%) were married, and 210 (65%) lived with someone. One hundred forty-five patients (46%) described a social network of 0-10 people; 110 (35%) of 11-25; and 58 (19%) of 26 or more. The Medical Outcomes Study (MOS) social support survey revealed that the median scores (range) for emotional/informational, tangible, positive social interaction, and affectionate social support were 94 (3, 100), 94 (0, 100), 96 (0, 100), and 100 (8, 100), respectively. Social support scores appeared stable over 2 years and higher (more support) than in other cancer settings. No statistically significant associations were observed between social support and survival and adverse events in multivariate analyses. However, married patients had smaller tumors, and those with arthritis reported less social support. CONCLUSION: Although social support did not predict survival and adverse events, the exploratory but plausible inverse associations with larger tumors and arthritis suggest that social support merits further study.

Management of Lung Cancer in the Elderly.

Lung cancer is the leading cause of cancer-associated mortality in the USA. The median age at diagnosis of lung cancer is 70 years, and thus, about one-half of patients with lung cancer fall into the elderly subgroup. There is dearth of high level of evidence regarding the management of lung cancer in the elderly in the three broad stages of the disease including early-stage, locally advanced, and metastatic disease. A major reason for the lack of evidence is the underrepresentation of elderly in prospective randomized clinical trials. Due to the typical decline in physical and physiologic function associated with aging, most elderly do not meet the stringent eligibility criteria set forth in age-unselected clinical trials. In addition to performance status, ideally, comorbidity, cognitive, and psychological function, polypharmacy, social support, and patient preferences should be taken into account before applying prevailing treatment paradigms often derived in younger, healthier patients to the care of the elderly patient with lung cancer. The purpose of this chapter was to review the existing evidence of management of early-stage, locally advanced disease, and metastatic lung cancer in the elderly.

Hemophagocytic Lymphohistiocytosis and Bone Marrow Hemophagocytosis: A 5-Year Institutional Experience at a Tertiary Care Hospital.

OBJECTIVE: The purpose of this study was to correlate the significance of bone marrow hemophagocytosis and analyze outcome data in patients with suspected hemophagocytic lymphohistiocytosis (HLH) at a tertiary care hospital during the course of 5 years. METHODS: The pathology database of State University of New York Upstate Medical University, Syracuse, was searched for the terms "hemophagocytosis," "hemophagocytic syndrome," and "hemophagocytic lymphohistiocytosis" encompassing the period January 2009-December 2014. Bone marrow aspirate and biopsy specimens, along with ancillary laboratory studies, clinical course, and outcome data, were reviewed for each case. RESULTS: Of the 23 patients included in our study, HLH was diagnosed in 14 (60.8%). Bone marrow hemophagocytosis (HPC) was seen in a higher proportion of patients (78.5%) who were diagnosed as having HLH; however, 55.5% of the patients who were not diagnosed as having HLH also showed evidence of bone marrow HPC. Patients with malignancy-associated HLH had a markedly worse outcome compared with patients with nonmalignancy-associated HLH. CONCLUSIONS: Although bone marrow HPC is fairly sensitive, it is not specific to establish a diagnosis of HLH. A high index of clinical suspicion together with early diagnosis and treatment is imperative to improve outcomes in patients suspected of having HLH.

Effect of age on the efficacy of adjuvant chemotherapy for resected non-small cell lung cancer.

BACKGROUND: Adjuvant chemotherapy after surgical resection improves outcomes for patients with early-stage non-small cell lung cancer (NSCLC). To the authors' knowledge, there are no published prospective trials to date of adjuvant chemotherapy after surgical resection administered exclusively in older patients. In the current study, the authors sought to evaluate the efficacy of adjuvant chemotherapy in older patients in a Veterans Health Administration cohort. METHODS: Patients who underwent surgical resection for American Joint Committee on Cancer stages IB to III NSCLC between 2001 and 2011 were analyzed. Data regarding patient demographics and comorbidities, tumor characteristics, and primary treatment were collected. Patients were divided into 2 groups based on age at diagnosis: those aged <70 years and those aged ≥70 years. The primary exposure was use of adjuvant chemotherapy. A Cox proportional hazards model was used to estimate the significance of patient characteristics. Survival curves were estimated using the Kaplan-Meier method and group comparisons were performed using the log-rank test. RESULTS: The analysis included 7593 patients who underwent surgical resection for stage IB to stage III NSCLC. Among these, 2897 patients (38%) were aged ≥70 years. The percentage of older patients who received adjuvant chemotherapy was approximately one-half that of younger patients who did so (15.3% vs 31.6%; P<.0001). Carboplatin-based doublets were used most often in all patients (64.6%). Both younger patients (hazard ratio, 0.79; 95% confidence interval, 0.72-0.86) and older patients (hazard ratio, 0.81; 95% confidence interval, 0.71-0.92) were found to have a lower risk of death with receipt of adjuvant chemotherapy. CONCLUSIONS: Older patients derive a similar magnitude of benefit from adjuvant chemotherapy as younger patients and therefore adjuvant chemotherapy should not be withheld based on age alone.
