Racial differences in treatment and survival among older patients with multiple myeloma

Cancer Medicine

Published On 2024/1/17

Background Treatments for multiple myeloma (MM) have evolved over time and improved MM survival. While racial differences in MM treatment and prognosis between non‐Hispanic African American (NHAA) and non‐Hispanic White (NHW) patients are well‐established, it is unclear whether they have persisted after the introduction of novel agents. Methods Using the Surveillance, Epidemiology, and End Results‐Medicare linked database, our study investigated racial difference in the receipt of treatment within 1 year following diagnosis and assessed survival outcomes among Medicare beneficiaries (≥66 years) diagnosed with MM from 2007 to 2017. We applied multivariable Cox proportional hazards models to estimate the association between race and survival and presented hazard ratios (HRs). Results Of 2094 NHAA and 11,983 NHW older patients with MM, 59.5% and 64.8% received treatment …

Veterans Health Administration: Decentralized clinical trials

Purpose: The Veterans Health Administration (VA) created National TeleOncology (NTO) service in 2019 to provide telehealth cancer care to Veterans and to augment care provided at VA facilities through a hub and spoke model. More recently, VA established a Decentralized Clinical Trials (DCTs) infrastructure to support clinical trials (CTs) that rely on telehealth, where research staff are at different locations, and/or where a single IRB provides oversight even when subjects are at different locations. Brief Description: Research support and infrastructure is variable across VA facilities resulting in uneven access to cancer CTs in the VA system. Veterans often live in rural areas or have transportation challenges, which are barriers to participate in CTs. The COVID-19 pandemic resulted in increased telehealth use in clinical care and in CTs, providing the rationale for a focused effort in DCTs. DCTs have the potential to …

Longitudinal latent class analysis to further understand trajectory of density over time and risk of breast cancer

Background: It is clinically important to refine strategies to manage women with dense breasts as they represent approximately 50% of all women screened. Change in breast density is related to risk of breast cancer.1 We also must understand this change in density over time in women with dense and non-dense breasts. While population level data have been reported to estimate decrease in density with age, this has largely used digitized film images.2 Expanding use of digital mammography and repeated screening generates a large library of images for each woman, offering the potential to use more of the image data. Methods: We use longitudinal latent class analysis to cluster women and estimate their change in density over time. To evaluate the groups of women with different patterns of change in density we fit latent class models to our previously published data.1 This includes 289 pathology confirmed …

Pharmacogenetic and clinical risk factors for bevacizumab-related gastrointestinal hemorrhage in prostate cancer patients treated on CALGB 90401 (Alliance)

The objective of this study was to discover clinical and pharmacogenetic factors associated with bevacizumab-related gastrointestinal hemorrhage in Cancer and Leukemia Group B (Alliance) 90401. Patients with metastatic castration-resistant prostate cancer received docetaxel and prednisone±bevacizumab. Patients were genotyped using Illumina HumanHap610-Quad and assessed using cause-specific risk for association between single nucleotide polymorphisms (SNPs) and gastrointestinal hemorrhage. In 1008 patients, grade 2 or higher gastrointestinal hemorrhage occurred in 9.5% and 3.8% of bevacizumab (n= 503) and placebo (n= 505) treated patients, respectively. Bevacizumab (P< 0.001) and age (P= 0.002) were associated with gastrointestinal hemorrhage.

The Association of Agent Orange Exposure with the progression of monoclonal gammopathy of undetermined significance to multiple myeloma: a population-based study of Vietnam War …

Herbicide and pesticide exposure [e.g., agent orange (AO)] is associated with an increased risk of multiple myeloma (MM) due to the contaminant, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). However, it is unclear whether TCDD/AO exposure (AO exposure hereafter) increases the risk of progression of monoclonal gammopathy of undetermined significance (MGUS) to MM. We sought to evaluate the association in a nationwide study of US Veterans. A natural language processing algorithm was used to confirm MGUS and progression to MM. We included Veterans who were diagnosed with MGUS from 10/1/1999 to 12/31/2021 and served during the Vietnam War Era from 1/9/1962 to 5/7/1975. AO exposure was stratified according to three TCDD exposure levels: high (1/9/1962–11/30/1965), medium (12/1/1965–12/31/1970), or low (1/1/1971–5/7/1975).

Exposure to Agent Orange is associated with increased recurrence after surgical treatment of stage I non–small cell lung cancer

ObjectiveApproximately 3 million Americans served in the armed forces during the Vietnam War. Veterans have a higher incidence rate of lung cancer compared with the general population, which may be related to exposures sustained during service. Agent Orange, one of the tactical herbicides used by the armed forces as a means of destroying crops and clearing vegetation, has been linked to the development of several cancers including non–small cell lung cancer. However, traditional risk models of lung cancer survival and recurrence often do not include such exposures. We aimed to examine the relationship between Agent Orange exposure and overall survival and disease recurrence for surgically treated stage I non–small cell lung cancer.MethodsWe performed a retrospective cohort study using a uniquely compiled dataset of US Veterans with pathologic I non–small cell lung cancer. We included adult …

Abstract PO5-09-02: Breast Tissue Proteomic Profile of Breast Cancer in Premenopausal Women and Association with Mammographic Breast Density

Introduction: Breast cancer incidence is rising in premenopausal, hence, there is a critical need to understand factors underlying premenopausal breast cancer development in order to guide targeted prevention. Mammographic breast density is a strong risk factor for, as well as an intermediate phenotype for premenopausal breast cancer. Yet, the molecular mechanisms underlying the associations of dense breasts with breast cancer are not well understood. Our objectives in this study are to perform proteomic analysis in breast tissues to (i) identify proteins that are associated with breast cancer development in premenopausal women; (ii) determine which of these proteins are also associated with dense breasts. Methods: We performed proteomic analysis on tumor and adjacent normal tissues from 50 premenopausal women with breast cancer who had breast tissue samples archived at the St. Louis Breast Tumor …

How does weight gain since the age of 18 years affect breast cancer risk in later life? A meta-analysis

Early life factors are important risk factors for breast cancer. The association between weight gain after age 18 and breast cancer risk is inconsistent across previous epidemiologic studies. To evaluate this association, we conducted a meta-analysis according to PRISMA guidelines and the established inclusion criteria. We performed a comprehensive literature search using Medline (Ovid), Embase, Scopus, Cochrane Library, and ClinicalTrials.gov to identify relevant studies published before June 3, 2022. Two reviewers independently reviewed the articles for final inclusion. Seventeen out of 4,725 unique studies met the selection criteria. The quality of studies was assessed using the Newcastle-Ottawa Scale (NOS), and all were of moderate to high quality with NOS scores ranging from 5 to 8. We included 17 studies (11 case-control, 6 cohort) in final analysis. In case-control studies, weight gain after age 18 was …

Abstract PO3-09-01: Integrating pathomic and radiomic images to classify risk of subsequent events among women with DCIS

Background Multiple sources of ~omic data can be generated from women at different stages of developing breast cancer, the leading cancer diagnosed in women worldwide. Traditionally interrogation of risk factors to study associations and develop prediction models for future breast events has been limited to one or few risk factors, or summary scores of clinical and tumor characteristics. Methods to bring mammography images and breast biopsies of precancer lesions together to summarize risk of cancer developing in the breast are urgently needed. Integration of these two sources has not been performed to date, but has potential to increase accuracy of risk prediction. Approach The Repository of Archival Human Breast Tissue (RAHBT) was established in 2007 at Washington University School of Medicine (WUSM) and maintains biospecimens and medical record data of women treated with breast-conserving …

Modeling correlated pairs of mammogram images

Mammography remains the primary screening strategy for breast cancer, which continues to be the most prevalent cancer diagnosis among women globally. Because screening mammograms capture both the left and right breast, there is a nonnegligible correlation between the pair of images. Previous studies have explored the concept of averaging between the pair of images after proper image registration; however, no comparison has been made in directly utilizing the paired images. In this paper, we extend the bivariate functional principal component analysis over triangulations to jointly characterize the pair of imaging data bounded in an irregular domain and then nest the extracted features within the survival model to predict the onset of breast cancer. The method is applied to our motivating data from the Joanne Knight Breast Health Cohort at Siteman Cancer Center. Our findings indicate that there was no …

Pectoral muscle removal in mammogram images: A novel approach for improved accuracy and efficiency

PurposeAccurate pectoral muscle removal is critical in mammographic breast density estimation and many other computer-aided algorithms. We propose a novel approach to remove pectoral muscles form mediolateral oblique (MLO) view mammograms and compare accuracy and computational efficiency with existing method (Libra).MethodsA pectoral muscle identification pipeline was developed. The image is first binarized to enhance contrast and then the Canny algorithm was applied for edge detection. Robust interpolation is used to smooth out the pectoral muscle region. Accuracy and computational speed of pectoral muscle identification was assessed using 951 women (1,902 MLO mammograms) from the Joanne Knight Breast Health Cohort at Washington University School of Medicine.ResultsOur proposed algorithm exhibits lower mean error of 12.22% in comparison to Libra’s estimated error of 20.44 …

Area-level socioeconomic deprivation is associated with inadequate access to quality preoperative care and increased readmission after surgery for early-stage lung cancer

Objective: Socioeconomic deprivation (SED) has been associated with higher lung cancer risk and mortality. However, the effects of SED on lung cancer outcomes in an integrated, single-payer healthcare system, such as the Veterans Health Administration (VHA), remains unknown. We sought to examine the impact of area-level SED on access to care and outcomes in veterans with early-stage non-small cell lung cancer (NSCLC). Methods: We conducted a retrospective cohort study of patients with clinical stage I NSCLC receiving definitive surgical treatment in the VHA from 2006-2016. Patients were assigned an area deprivation index (ADI) score, a ZIP code-level measure of SED incorporating multiple poverty, education, housing, and employment indicators from the United States Census. Using multivariable analysis, we evaluated the relationship between ADI and guideline-concordant quality metrics (QMs …

Leisure time television watching, computer use and risks of breast, colorectal and prostate cancer: A Mendelian randomisation analysis

Background Sedentary behaviours have been associated with increased risks of some common cancers in epidemiological studies; however, it is unclear if these associations are causal. Methods We used univariable and multivariable two‐sample Mendelian randomisation (MR) to examine potential causal relationships between sedentary behaviours and risks of breast, colorectal and prostate cancer. Genetic variants associated with self‐reported leisure television watching and computer use were identified from a recent genome‐wide association study (GWAS). Data related to cancer risk were obtained from cancer GWAS consortia. A series of sensitivity analyses were applied to examine the robustness of the results to the presence of confounding. Results A 1‐standard deviation (SD: 1.5 h/day) increment in hours of television watching increased risk of breast cancer (OR per 1‐SD: 1.15, 95% confidence …

Tumor therapy by targeting extracellular hydroxyapatite using novel drugs: A paradigm shift

Background It has been shown that tumor microenvironment (TME) hydroxyapatite (HAP) is typically associated with many malignancies and plays a role in tumor progression and growth. Additionally, acidosis in the TME has been reported to play a key role in selecting for a more aggressive tumor phenotype, drug resistance and desensitization to immunotherapy for many types of cancers. TME‐HAP is an attractive target for tumor detection and treatment development since HAP is generally absent from normal soft tissue. We provide strong evidence that dissolution of hydroxyapatite (HAP) within the tumor microenvironment (TME‐HAP) using a novel therapeutic can be used to kill cancer cells both in vitro and in vivo with minimal adverse effects. Methods We developed an injectable cation exchange nano particulate sulfonated polystyrene solution (NSPS) that we engineered to dissolve TME‐HAP …

Exploring resonance theory and uncontrollability during co‐creative art making: A qualitative study among cancer patients

Purpose Co‐creation, characterised by artists and patients creating a joint work of art, may support patients with the integration of life events, such as living with cancer, into their life story. In the process of co‐creation, resonance relationships between patients, artists and material may evolve that support such integration. Using the framework of resonance theory, we aim to investigate if and how patients move through the three phases of resonance during a process of co‐creation and explore the role of uncontrollability in this process. Methods Ten patients who received cancer treatment with palliative intent completed co‐creation processes, which were audio recorded. These recordings were imported in Atlas‐Ti and analysed by applying content analysis. We searched for the three phases of resonance, Being affected, touched and moved; Self‐efficacy and responding; Adaptive transformation. We additionally …

Restricted life‐space mobility impacts physical but not mental quality of life in older cancer survivors

Background Older cancer survivors often value quality of life (QOL) over survival. Life‐space mobility (LSM), defined as the individual's spatial geographic mobility range, is an important QOL indicator in older adults with chronic illnesses; however, this relationship is unexplored in older cancer survivors. Methods We examined the longitudinal associations and causal relationships between LSM and QOL in 153 older cancer survivors (≥65 years) from the University of Alabama at Birmingham (UAB) Study of Aging. LSM was assessed using the UAB Life‐Space Assessment‐Composite score (LSA‐C), and QOL was assessed by the SF‐12 Mental Component Score (MCS12) and Physical Component Score (PCS12) at 0 (study entry), 6, 18, 36, 54, and 72 months.

Common and distinct risk factors that influence more severe and distressing shortness of breath profiles in oncology outpatients

Background Shortness of breath occurs in 10%–70% of oncology patients. Very little is known about interindividual variability in its severity and distress and associated risk factors. Using latent profile analyses (LPAs), purpose was to identify subgroups of patients with distinct severity and distress profiles for shortness of breath as single symptom dimensions. In addition, a joint LPA was done using patients' severity AND distress ratings. For each of the three LPAs, differences among the shortness of breath classes in demographic, clinical, symptom, stress, and resilience characteristics were evaluated. Methods Patients completed ratings of severity and distress from shortness of breath a total of six times over two cycles of chemotherapy. All of the other measures were completed at enrollment (i.e., prior to the second or third cycle of chemotherapy). Separate LPAs were done using ratings of severity and distress, as …

Access to innovative therapies in pediatric oncology: Report of the nationwide experience in Canada

Background The need for new therapies to improve survival and outcomes in pediatric oncology along with the lack of approval and accessible clinical trials has led to “out‐of‐trial” use of innovative therapies. We conducted a retrospective analysis of requests for innovative anticancer therapy in Canadian pediatric oncology tertiary centers for patients less than 30 years old between 2013 and 2020. Methods Innovative therapies were defined as cancer‐directed drugs used (a) off‐label, (b) unlicensed drugs being used outside the context of a clinical trial, or (c) approved drugs with limited evidence in pediatrics. We excluded cytotoxic chemotherapy, cellular products, and cytokines. Results We retrieved data on 352 innovative therapy drug requests.

Awareness and interest in cannabis use for cancer management among cancer survivors

Background We examined the awareness, interest, and information sources relating to cannabis use for cancer management (including management of cancer symptoms and treatment‐related side effects) and determined factors associated with cancer survivors' awareness and interest in learning about cannabis use for cancer management. Methods This was a cross‐sectional study of adult cancer survivors (N = 1886) receiving treatment at a comprehensive cancer center. Weighted prevalence and multivariable logistic regression analyses were conducted. Results Among cancer survivors, 88% were aware and 60% were interested in learning about cannabis use for cancer management. Common sources of information to learn about cannabis use for cancer management were cancer doctors/nurses (82%), other patients with cancer (27%), websites/blogs (26%), marijuana stores (20%), and family/friends …

Identifying priority areas to support primary care engagement in breast cancer survivorship care: A Delphi study

IntroductionExisting approaches in cancer survivorship care delivery have proven to be insufficient to engage primary care. This study aimed to identify stakeholder-informed priorities to improve primary care engagement in breast cancer survivorship care.MethodsExperts in U.S. cancer survivorship care delivery were invited to participate in a 4-round online Delphi panel to identify and evaluate priorities for defining and fostering primary care's engagement in breast cancer survivorship. Panelists were asked to identify and then assess (ratings of 1-9) the importance and feasibility of priority items to support primary care engagement in survivorship. Panelists were asked to review the group results and reevaluate the importance and feasibility of each item, aiming to reach consensus.ResultsRespondent panelists (n = 23, response rate 57.5%) identified 31 priority items to support survivorship care. Panelists …

Racial differences in treatment and survival among older patients with multiple myeloma

Background Treatments for multiple myeloma (MM) have evolved over time and improved MM survival. While racial differences in MM treatment and prognosis between non‐Hispanic African American (NHAA) and non‐Hispanic White (NHW) patients are well‐established, it is unclear whether they have persisted after the introduction of novel agents. Methods Using the Surveillance, Epidemiology, and End Results‐Medicare linked database, our study investigated racial difference in the receipt of treatment within 1 year following diagnosis and assessed survival outcomes among Medicare beneficiaries (≥66 years) diagnosed with MM from 2007 to 2017. We applied multivariable Cox proportional hazards models to estimate the association between race and survival and presented hazard ratios (HRs). Results Of 2094 NHAA and 11,983 NHW older patients with MM, 59.5% and 64.8% received treatment …

Prediction of prognosis in oral squamous cell carcinoma using infrared microspectroscopy

Background Estimation of prognosis of oral squamous cell carcinoma (OSCC) is inaccurate prior to surgery, only being effected following subsequent pathological analysis of the primary tumour and excised lymph nodes. Consequently, a proportion of patients are overtreated, with an increase in morbidity, or undertreated, with inadequate margins and risk of recurrence. We hypothesise that it is possible to accurately characterise clinical outcomes from infrared spectra arising from diagnostic biopsies. In this first step, we correlate survival with IR spectra derived from the primary tumour. Methods Infrared spectra were collected from tumour tissue from 29 patients with OSCC and subject to classification modelling. Results The model had a median AUROC of 0.89 with regard to prognosis, a median specificity of 0.83, and a hazard ratio of 6.29 in univariate Cox proportional hazard modelling. Conclusion The data …

Clinicopathological and genomic features of superficial esophageal squamous cell carcinomas in nondrinker, nonsmoker females

Background Esophageal squamous cell carcinoma (ESCC) is sometimes detected in non‐drinker and non‐smoker females who are considered to have very low risk of ESCC development in daily practice. This study examined the clinicopathological and genomic characteristics of ESCCs in females with no history of drinking and smoking. Methods The sample comprised 118 ESCC lesions occurring in 95 female patients who underwent endoscopic submucosal dissection at our department between January 2008 and December 2019. The patients were categorized into two groups: 51 lesions in 49 patients with no history of drinking and smoking (nondrinker/nonsmoker [NDNS] group) and 69 lesions in 45 patients with a history of drinking or smoking (drinker/smoker [DS] group). We analyzed the differences in clinicopathological and cancerous genomic characteristics between the groups. Significant genomic …

Dickkopf 1 is expressed in normal fibroblasts during early stages of colorectal tumorigenesis

Background and Purpose Colorectal cancer progression from adenoma to cancer is a time‐intensive process; however, the interaction between normal fibroblasts (NFs) with early colorectal tumors, such as adenomas, remains unclear. Here, we analyzed the response of the microenvironment during early tumorigenesis using co‐cultures of organoids and NFs. Materials and Methods Colon normal epithelium, adenoma, cancer organoid, and NFs were established and co‐cultured using Transwell inserts. Microarray analysis of NFs was performed to identify factors expressed early in tumor growth. Immunostaining of clinical specimens was performed to localize the identified factor. Functional analysis was performed using HCT116 cells. Serum DKK1 levels were measured in patients with colorectal cancer and adenoma. Results Colorectal organoid–NF co‐culture resulted in increased organoid diameter and cell …

CaRE@ ELLICSR: Effects of a clinically integrated, group‐based, multidimensional cancer rehabilitation program

Background Although oncology clinical practice guidelines recognize the need and benefits of exercise, the implementation of these services into cancer care delivery remains limited. We developed and evaluated the impact of a clinically integrated 8‐week exercise and education program (CaRE@ELLICSR). Methods We conducted a mixed methods, prospective cohort study to examine the effects of the program. Each week, participants attended a 1‐h exercise class, followed by a 1.5‐h education session. Questionnaires, 6‐min walk tests (6MWT), and grip strength were completed at baseline (T0), 8 weeks (T1), and 20 weeks (T2). Semi‐structured interviews were conducted with a sub‐sample of participants about their experience with the program. Results Between September 2017 and February 2020, 277 patients enrolled in the program and 210 consented to participate in the research study. The mean …
