PURPOSE: Hospitalizations during cancer treatment are costly, can impair quality of life, and negatively affect therapy completion. Our objective was to identify risk factors for unplanned hospitalization among older adults receiving chemotherapy. METHODS: This is a secondary analysis of a multisite cohort study (N = 750) of patients ≥ 65 years of age evaluated with a geriatric assessment (GA) to predict chemotherapy toxicity. The primary outcome of this analysis was unplanned hospitalizations during treatment; the secondary outcome was length of stay (LOS) of the first hospitalization. Independent variables included pretreatment GA measures, laboratory values, cancer type and stage, and treatment intensity characteristics. We used logistic regression to estimate the odds of hospitalization and generalized linear models for LOS in multivariable analyses. RESULTS: The sample median age was 72 years (range, 65-94 years); 59% had stage IV disease. At least one unplanned hospitalization occurred in 193 patients (25.7%) during receipt of chemotherapy. In multivariable analyses controlling for cancer type, the following baseline characteristics were significantly associated with increased odds of hospitalization: needing help bathing or dressing (odds ratio [OR], 1.8; 95% CI, 1.0 to 3.1), polypharmacy (≥ 5 meds) (OR, 1.6; 95% CI, 1.1 to 2.4), more comorbid conditions (OR, 1.1; 95% CI, 1.0 to 1.3), availability of someone to take them to the doctor (OR, 2.0; 95% CI, 1.0 to 4.1), CrCl < 60 mL/min (OR, 1.7; 95% CI, 1.1 to 2.4), and albumin < 3.5 g/dL (OR, 1.8; 95% CI, 1.2 to 2.8). In multivariable analyses, older age, self-reported presence of liver or kidney disease, living alone and depressive symptoms were associated with longer LOS. CONCLUSION: Readily available GA variables and laboratory data, but not age, were associated with unplanned hospitalizations among older adults receiving chemotherapy. If validated, these data can inform prediction models and the design of interventions to decrease unplanned hospitalizations.
BACKGROUND/OBJECTIVESCaregivers of older adults with cancer assist both with cancer care and other health issues, which may make them vulnerable to consequences of caregiving. Hospitalization may represent a time when a caregiver's ability to provide care at home is exceeded. We sought to characterize caregivers of hospitalized older adults with cancer, determine their quality of life (QOL), and identify factors associated with caregiver QOL.METHODSPatients (n = 100), aged 65 years and older, with an unplanned hospitalization and their caregivers were included. Caregivers completed a questionnaire about their health, social support, caregiving relationship, QOL (Caregiver Quality of Life Index‐Cancer [CQOLC] tool), and patient function. Patient medical history was obtained via chart review. The association between patient, caregiving, and caregiver factors and CQOLC was determined using multivariate linear regression.RESULTSMost patients (73%) had metastatic/advanced disease, and 71% received treatment for their cancer within 30 days of hospitalization. Median Karnofsky Performance Status (KPS) was 60%, and 89% required help with instrumental activities of daily living, as reported by caregivers. Median caregiver age was 65 years (range = 29‐84 years). The majority (60%) had no major comorbidities and rated their health as excellent/good (79%), though 22% reported worsening health due to caregiving. Caregivers had a median Mental Health Inventory‐18 score of 70 (range = 0–97), a median Medical Outcomes Study (MOS)‐social activity score of 56 (range = 0–87.5), and a median MOS‐Social Support Survey score of 68 (range = 0–100). Caregivers provided a median of 35 hours of care per week (range = 0‐168 hours of care per week). Mean CQOLC was 84.6 ± 23.5. Lower caregiver QOL was associated with poorer caregiver mental health, less social support, and poorer patient KPS (P < .05).CONCLUSIONCaregivers of hospitalized older adults with cancer are older but generally in good health. Those with poorer mental health, less social support, and caring for patients with poorer performance status are more likely to experience lower QOL. J Am Geriatr Soc 67:978–986, 2019.
BACKGROUND:Pathologic complete response (pCR) is associated with better prognosis and guides management for patients with advanced rectal cancer. Response rates vary between series for unclear reasons. We examine whether the thoroughness of pathologic assessment explains differences in pCR rates.METHODS:We retrospectively reviewed pathology reports from patients with stage II/III rectal cancer who underwent chemoradiation and resection in a prospective, multicenter trial. We utilized a novel measure for the thoroughness of pathologic assessment by dividing residual tumor size by the number of cassettes evaluated (tumor size to cassette ratio, TSCR), and evaluated whether TSCR is associated with pCR. We validated our findings using a separate cohort.RESULTS:From the trial cohort, 71 of 247 (29%) patients achieved pCR. The pCR rate ranged from 0 to 45% and mean TSCR ranged 0.29 to 0.87 across 12 institutions. Within each institution, a lower TSCR was associated with pCR, demonstrating a higher degree of thoroughness used for tumors that achieved pCR. Moreover, across all samples, low TSCR was independently associated with pCR on multivariable analysis. This finding was corroborated in a separate cohort of 201 tumors evaluated by five pathologists; each pathologist had a lower mean TSCR for pCR calls compared with non-pCR calls. However, the mean TSCR for an institution was not associated with its overall pCR rate.CONCLUSIONS:Pathologists assess rectal cancers that have responded significantly to neoadjuvant therapy more thoroughly. Thoroughness does not appear to explain differences in pCR rates between institutions. Our results suggest pCR is not a sampling artifact.
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.
BACKGROUND Rural women have limited access to breast cancer education, which partially contributes to late diagnosis and treatment. In this pilot study, we tested the feasibility of implementing a school-based breast cancer educational program for adolescents in a rural Mexican community. We hypothesized that the adolescents' knowledge on breast cancer would increase as a result of the program, and that there would be intergenerational transmission of that knowledge to their older female relatives. MATERIALS AND METHODS Female adolescents from a rural middle school received the educational program. The program would be considered feasible and acceptable if more than 75% reported being satisfied with its contents. Changes in knowledge in the students and their relatives were evaluated using baseline and 4 months follow-up questionnaires. RESULTS One hundred twenty-six students were enrolled. The program was considered acceptable by 96% of the participants. The students' knowledge regarding breast cancer increased significantly from baseline to 4 months follow-up (63% to 82%). One hundred ninety-four female relatives completed the initial knowledge questionnaires. The relatives' knowledge regarding breast cancer showed a significant increase from baseline to 4 months follow-up (55% to 61%). CONCLUSION Implementing breast cancer educational programs for adolescents in rural communities is feasible and acceptable. The program increased the adolescents' knowledge on breast cancer, and promoted the intergenerational transmission of that knowledge to their female relatives. Intergenerational transmission of knowledge represents a potential method for providing population-based health awareness education globally. IMPLICATIONS FOR PRACTICE In limited-resource settings, education is a valuable tool for achieving early detection and downstaging of breast cancer. Unfortunately, rural women lack access to educational opportunities and information about breast cancer, which is a factor contributing to late diagnosis and treatment. In this study, we demonstrated that implementing a school-based breast cancer educational program for female adolescents in a rural Mexican community was feasible, acceptable, and increased their knowledge about breast cancer. Furthermore, the program encouraged the transmission of information to the students' older relatives. Intergenerational transmission of knowledge represents a novel and potentially effective tool in cancer education and promotion.
Subclinical oral human papillomavirus (HPV) infection that persists for decades is likely to precede an HPV-driven squamous cell carcinoma of the head and neck, but little is known about the natural history of oral HPV. We systematically reviewed and abstracted data from nine manuscripts that examined human immunodeficiency virusnegative and cancer-free subjects for oral HPV DNA to determine the pooled baseline prevalence and incidence of newly acquired oral HPV infections, and specifically for HPV-16. We also documented the clearance rate and the median time to clearance, where data existed. Of 3762 individuals, 7.5% had an oral infection with any HPV type (1.6% for HPV-16). Meta-regression analysis estimated the 12-month cumulative incidence to be 4.8% (95% confidence interval 3.2-7.3 %). The overall oral HPV clearance was reported to be 0-80% between studies, and the median time to clearance from 6.5 to 18 months. Oral HPV-16 clearance was 43-83 %, and median time to clearance for HPV-16 was 7-22 months. Oral HPV prevalence, incidence and clearance vary considerably between published studies from different geographical regions. Further research is required to identify predictors of persistent oral HPV infection. Measurable baseline prevalence was observed in all studies, as well as non-trivial incidence of newly acquired oral HPV infections and incomplete clearance.
696 Background: A pathologic complete response (pCR) after neoadjuvant therapy and surgical excision is associated with a better prognosis and guides the management of patients with locally advanced rectal cancer. It is not known whether the thoroughness of pathologic assessment correlates with the finding of pCR. Methods: We introduce a surrogate measure for the thoroughness of pathologic assessment by taking the ratio of maximum residual tumor size and the number of cassettes prepared from the tumor: the Tumor Size to Cassette Ratio (TSCR). We retrospectively reviewed pathology reports from 259 patients with Stage II/III rectal cancer enrolled in a multicenter prospective clinical trial to determine whether TSCR is associated with pCR. Results: Of 247 included patients, 71 (29%) had a pCR. The pCR rate ranged from 0-45% and TSCR ranged from 0.0004 to 1.67 across the twelve trial sites. TSCR was significantly associated with pCR on univariable analysis. On multivariable analysis, TSCR remained significantly associated with pCR (odds ratio of 0.05; 95% CI 0.008-0.302) after adjusting for clinical stage, tumor size, distance from anal verge, radiation dose, and the number of neoadjuvant cycles of FOLFOX received. Conclusions: Pathologists tend to assess rectal cancer specimens with a pCR more thoroughly, but the thoroughness of pathologic assessment of residual tumor specimens varies between institutions. The thoroughness of pathologic assessment is associated with pCR. This raises the need for further standardization in the assessment of rectal cancer specimens after neoadjuvant chemoradiation.
Chemotherapy decreases the risk of relapse and mortality in early-stage breast cancer (BC), but it comes with the risk of toxicity. Chemotherapy efficacy depends on relative dose intensity (RDI), and an RDI < 85% is associated with worse overall survival. The pro-inflammatory (interleukin (IL)-6, C-reactive protein (CRP)) and coagulation factors (D-dimer) serve as biomarkers of aging. The purpose of this study is to determine if these biomarkers are associated with reduced RDI in women with stage I–III BC.
Aim . To examine the association between lifetime alcohol consumption and significant liver disease in type 2 diabetic patients with NAFLD. Methods . A cross-sectional study assessing 151 patients with NAFLD at risk of clinically significant liver disease. NAFLD fibrosis severity was classified by transient elastography; liver stiffness measurements ≥8.2 kPa defined significant fibrosis. Lifetime drinking history classified patients into nondrinkers, light drinkers (always ≤20 g/day), and moderate drinkers (any period with intake >20 g/day). Result . Compared with lifetime nondrinkers, light and moderate drinkers were more likely to be male ( p = 0.008) and to be Caucasian ( p = 0.007) and to have a history of cigarette smoking ( p = 0.000), obstructive sleep apnea ( p = 0.003), and self-reported depression ( p = 0.003). Moderate drinkers required ≥3 hypoglycemic agents to maintain diabetic control ( p = 0.041) and fibrate medication to lower blood triglyceride levels ( p = 0.044). Compared to lifetime nondrinkers, light drinkers had 1.79 (95% CI: 0.67–4.82; p = 0.247) and moderate drinkers had 0.91 (95% CI: 0.27–3.10; p = 0.881) times the odds of having liver stiffness measurements ≥8.2 kPa (adjusted for age, gender, and body mass index). Conclusions . In diabetic patients with NAFLD, light or moderate lifetime alcohol consumption was not significantly associated with liver fibrosis. The impact of lifetime alcohol intake on fibrosis progression and diabetic comorbidities, in particular obstructive sleep apnea and hypertriglyceridemia, requires further investigation.
Background. As patients age, caregivers increasingly provide essential support and patient information. We sought to determine if patient-caregiver assessments of patient health differ and if differences contribute to burden in caregivers of older adults with cancer. Materials and Methods. One hundred patients, aged >= 65, and their caregivers independently assessed patient function, comorbidity, nutrition, social activity, social support, and mental health. Caregivers completed the Caregiver Strain Index (CSI). Patient-caregiver assessments were compared using the Wilcoxon signed rank test and paired t test. Association between caregiver burden and differences between patient-caregiver assessments was examined using generalized linear regression. Results. Median patient age was 70 (range 65-91) and 70% had advanced disease. Sixty percent of patients reported requiring help with instrumental activities of daily living (IADLs); most had good social support (median Medical Outcomes Study MOS]-Social Support Survey score 92) and mental health (median Mental Health Inventory score 85). Caregivers were a median age of 66 (range 28-85), 73% female, 68% spousal caregivers, and 79% lived with the patient. Caregivers rated patients as having poorer physical function (more IADLs dependency [p = .008], lower Karnofsky Performance Status [p = .02], lower MOS-Physical Function [p < .0001]), poorer mental health (p = .0002), and having more social support (p = .03) than patients themselves. Three-quarters of caregivers experienced some caregiver burden (mean CSI score 3.1). Only differences in patient-caregiver assessment of the patient's need for help with IADLs were associated with increased caregiver burden (p = .03). Conclusion. Patient-caregiver assessments of patient function, mental health, and social support differ. However, only differences in assessment of IADLs dependency were associated with increased caregiver burden.
10057Background: Older patients with cancer are at increased risk of hospitalizations during cancer treatment. Our objective was to identify risk factors for unplanned hospitalization among older adults receiving chemotherapy. Methods: We conducted a secondary analysis of a multi-site cohort study (N = 500) of patients ≥ 65 years evaluated with a geriatric assessment (GA) to predict chemotherapy toxicity. The primary outcome wasincident toxicity-related hospitalization during treatment. Predictor variables included: 1) pretreatment GA measures assessing functional status (self-reported and objectively measured), falls, self-reported co-morbidity, mood, social activity and support, nutrition, cognition, and polypharmacy; 2) baseline laboratory values (creatinine clearance [CrCl] by Cockcroft-Gault, hemoglobin, albumin); 3) cancer type and stage; and 4) treatment (mono vs. poly-chemotherapy and dosing). Logistic regression was used to estimate the odd ratio (OR) of hospitalization in multivariate analyses. ...
In order to assess the broad-scale applicability of field releases of Wolbachia for the biological control of insect-transmitted diseases, we determined the relationship between the larval diet of Aedes aegypti L. mosquitoes infected with Wolbachia strains and their susceptibility to dengue virus (DENV) infection via intrathoracic injection and oral inoculation. Larvae were reared on diets that varied in the quantity of food which had the effect of modifying development time and adult body size. Wolbachia wMel infection was associated with highly significant reductions in dengue serotype 2 (DENV-2) infection rates of between 80 and 97.5% following intrathoracic injection of adults emerging from three diet levels. Reductions were 100% in two diet level treatments following oral inoculation. Similarly, wMelPop infection was associated with highly significant reductions in DENV-2 infection rates of between 95 and 100% for intrathoracic injection and 97.5 and 100% for oral inoculation across diet level treatments. Larval diet level had no significant effect on DENV-2 infection rates in the presence of Wolbachia infection in mosquitoes that were intrathoracically injected with the virus. This indicates that the effectiveness of Wolbachia on vector competence disruption within Ae. aegypti is unlikely to be compromised by variable larval nutrition in field settings.
Knowledge regarding compositions of proteomes at the proteoform level enhances insights into cellular phenotypes. A strategy is described herein for discovery of proteoform-specific information about cellular proteomes. This strategy involved analysis of data obtained by bottom-up mass spectrometry of multiple protein OGE separations on a fraction by fraction basis. The strategy was exemplified using five matched sets of lysates of uninfected and human respiratory syncytial virus-infected A549 cells. Template matching demonstrated that 67.3% of 10475 protein profiles identified focused to narrow pI windows indicative of efficacious focusing. Furthermore, correlation between experimental and theoretical pI gradients indicated reproducible focusing. Based on these observations a proteoform profiling strategy was developed to identify proteoforms, detect proteoform diversity and discover potential proteoform regulation. One component of this strategy involved examination of the focusing profiles for protein groups. A novel concordance analysis facilitated differentiation between proteoforms, including proteoforms generated by alternate splicing and proteolysis. Evaluation of focusing profiles and concordance analysis were applicable to cells from a single and/or multiple biological states. Statistical analyses identified proteoform variation between biological states. Regulation relevant to cellular responses to human respiratory syncytial virus was revealed. Western blotting and Protomap analyses validated the proteoform regulation. Discovery of STAT1, WARS, MX1, and HSPB1 proteoform regulation by human respiratory syncytial virus highlighted the impact of the profiling strategy. Novel truncated proteoforms of MX1 were identified in infected cells and phosphorylation driven regulation of HSPB1 proteoforms was correlated with infection. The proteoform profiling strategy is generally applicable to investigating interactions between viruses and host cells and the analysis of other biological systems.
Background: Gleason Score (GS) upgrading is generally considered a trigger for exit to definitive treatment during active surveillance (AS). Predicting the potential for GS upgrading would be of value in assessing AS eligibility. Methods: We assessed the performance of biomarkers in presurgical specimens of expressed prostatic secretion (EPS) in this setting. Results: Although EPS volume, total recovered RNA, and RNA expression biomarkers (TMPRSS2: ERG, PCA3, PSA) have been successful in both biopsy outcome prediction, and in the prediction of upstaging in active surveillance eligible patients, they were unable to predict upgrading in patients eligible for active surveillance under National Comprehensive Cancer Network guidelines. Conclusions: These biomarkers do not improve the prediction of upgrading over indications from standard clinical parameters. Impact: Additional biomarkers will be needed in this area.

Background: Neoadjuvant chemoradiation therapy (CRT) increases pathological complete response (pCR) rates compared to radiotherapy alone in patients with stage II-III rectal cancer. Limited evidence addresses whether radiotherapy dose escalation further improves pCR rates. Our purpose is to measure the effects of radiotherapy dose and other factors on post-therapy pathologic tumor (ypT) and nodal stage in rectal cancer patients treated with neoadjuvant CRT followed by mesorectal excision.Material and methods: A non-randomized comparative effectiveness analysis was performed of rectal cancer patients treated in 2000-2013 from the National Oncology Data Alliance (TM) (NODA), a pooled database of cancer registries from > 150 US hospitals. The NODA contains the same data submitted to state cancer registries and SEER combined with validated radiotherapy and chemotherapy records. Eligible patients were treated with neoadjuvant CRT followed by proctectomy and had complete data on treatment start dates, radiotherapy dose, clinical tumor (cT) and ypT stage, and number of positive nodes at surgery (n = 3298 patients). Multivariable logistic regression was used to assess the predictive value of independent variables on achieving a pCR.Results: On multivariable regression, radiotherapy dose, cT stage, and time interval between CRT and surgery were significant predictors of achieving a pCR. After adjusting for the effect of other variates, patients treated with higher radiotherapy doses were also more likely to have negative nodes at surgery and be downstaged from cT3-T4 and/or node positive disease to ypT0-T2N0 after neoadjuvant CRT.Conclusion: Our study suggests that increasing dose significantly improved pCR rates and downstaging in rectal cancer patients treated with neoadjuvant CRT followed by surgery.
