[PMID: 37263065 DOI: 10.1016/j.jgo.2023.101520] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 04/19/2023] [Accepted: 05/02/2023] [Indexed: 06/03/2023]
Abstract
INTRODUCTION Abiraterone and enzalutamide are treatments for metastatic castration-resistant prostate cancer (mCRPC). Due to a lack of head-to-head trials, they are prescribed interchangeably. However, the drugs have different pharmacokinetics and thus may have differing efficacy and adverse effects influenced by patient functional status and comorbid diseases. Additionally, mCRPC mainly affects older adults and since the prevalence of frailty increases with age, frailty is an important patient factor to consider in personalizing drug selection. MATERIALS AND METHODS We conducted a retrospective observational study of US veterans treated with abiraterone or enzalutamide for mCRPC from September 2014 to June 2017. Frailty was assessed using the Veterans Affairs Frailty Index (VA-FI), which utilizes administrative codes to assign a standardized frailty score. Patients were categorized as frail if VA-FI scores were > 0.2. The primary outcome was difference in overall survival (OS) between the two treatment groups. Cox regression modeling and propensity score matching was used to compare between abiraterone and enzalutamide treatments. RESULTS We identified 5,822 veterans, 57% of whom were initially treated with abiraterone and 43% with enzalutamide. Frail patients (n = 2,314; 39.7%) were older, with a mean age of 76.1 versus 74.9 years in the non-frail group (n = 3,508; 60.3%, p < 0.001) and had shorter OS compared to non-frail patients regardless of treatment group (18.5 vs. 26.6 months, p < 0.001). Among non-frail patients there was no significant difference in OS between abiraterone and enzalutamide treatment (27.7 vs 26.1 months, p = 0.07). However, frail patients treated with enzalutamide versus abiraterone had improved OS (20.7 vs 17.2 months, p < 0.001). In a propensity score matched analysis of frail patients (n = 2,070), enzalutamide was associated with greater median OS (24.1 vs 20.9 months, p < 0.001). In patients with dementia, enzalutamide was associated with longer OS (19.4 vs. 16.6 months, p = 0.003). DISCUSSION In this study of 5822 US veterans with mCRPC, treatment with enzalutamide was associated with improved OS compared to abiraterone among frail veterans and veterans with dementia, but not among non-frail veterans. Future studies should evaluate interactions between frailty and cancer treatments to optimize selection of therapy among frail adults.

Abstract
WHAT IS THIS SUMMARY ABOUT? This is a summary of a publication about Black participants of the GRIFFIN clinical study that was published in Blood Cancer Journal in April 2022. The GRIFFIN clinical study looked at the treatment combination of daratumumab plus a standard therapy for multiple myeloma (called RVd therapy, which stands for lenalidomide, bortezomib, and dexamethasone) in adult patients who had not been treated before for multiple myeloma and so were considered to have newly diagnosed multiply myeloma. Multiple myeloma is a blood cancer of plasma cells. Based on the participants' age, medical history, and indicators of good general health, the participants in the GRIFFIN study were also eligible to receive autologous stem cell transplant as part of their therapy. This summary describes results for the Black participants of the GRIFFIN clinical study who received daratumumab plus RVd therapy (called D-RVd) to see if D-RVd therapy is better than RVd therapy at reducing the amount of multiple myeloma cancer cells in a patient's body. WHY DID THE RESEARCHERS EVALUATE THE RESULTS FOR BLACK PATIENTS IN THE GRIFFIN STUDY? Due to racial disparities leading to historically low representation of minority groups in clinical studies, optimal treatments are not defined for Black patients with newly diagnosed multiple myeloma. Since previously published results from the overall population in the GRIFFIN study indicated that D-RVd therapy was better than RVd therapy, the researchers wanted to determine if this was also the case among Black participants. WHAT WERE THE RESULTS? Out of 207 participants in the GRIFFIN study, 15% (32 participants) were Black and 78% (161 participants) were White. In both Black and White participants, D-RVd therapy reduced the amount of myeloma cancer cells more than RVd therapy. Additionally, D-RVd and RVd therapy had similar safety results for Black and White participants. WHAT DO THE RESULTS MEAN? This analysis of GRIFFIN by race shows that Black people benefit from the daratumumab-containing D-RVd therapy as much as White people. Additionally, D-RVd therapy had similar safety results to RVd therapy for both Black and White people. Clinical Trial Registration: NCT02874742 (ClinicalTrials.gov).

Abstract
BACKGROUND Older adults with advanced cancer are at a high risk for treatment toxic effects. Geriatric assessment evaluates ageing-related domains and guides management. We examined whether a geriatric assessment intervention can reduce serious toxic effects in older patients with advanced cancer who are receiving high risk treatment (eg, chemotherapy). METHODS In this cluster-randomised trial, we enrolled patients aged 70 years and older with incurable solid tumours or lymphoma and at least one impaired geriatric assessment domain who were starting a new treatment regimen. 40 community oncology practice clusters across the USA were randomly assigned (1:1) to the intervention (oncologists received a tailored geriatric assessment summary and management recommendations) or usual care (no geriatric assessment summary or management recommendations were provided to oncologists) by means of a computer-generated randomisation table. The primary outcome was the proportion of patients who had any grade 3-5 toxic effect (based on National Cancer Institute Common Terminology Criteria for Adverse Events version 4) over 3 months. Practice staff prospectively captured toxic effects. Masked oncology clinicians reviewed medical records to verify. The study was registered with ClinicalTrials.gov, NCT02054741. FINDINGS Between July 29, 2014, and March 13, 2019, we enrolled 718 patients. Patients had a mean age of 77·2 years (SD 5·4) and 311 (43%) of 718 participants were female. The mean number of geriatric assessment domain impairments was 4·5 (SD 1·6) and was not significantly different between the study groups. More patients in intervention group compared with the usual care group were Black versus other races (40 [11%] of 349 patients vs 12 [3%] of 369 patients; p<0·0001) and had previous chemotherapy (104 [30%] of 349 patients vs 81 [22%] of 369 patients; p=0·016). A lower proportion of patients in the intervention group had grade 3-5 toxic effects (177 [51%] of 349 patients) compared with the usual care group (263 [71%] of 369 patients; relative risk [RR] 0·74 (95% CI 0·64-0·86; p=0·0001). Patients in the intervention group had fewer falls over 3 months (35 [12%] of 298 patients vs 68 [21%] of 329 patients; adjusted RR 0·58, 95% CI 0·40-0·84; p=0·0035) and had more medications discontinued (mean adjusted difference 0·14, 95% CI 0·03-0·25; p=0·015). INTERPRETATION A geriatric assessment intervention for older patients with advanced cancer reduced serious toxic effects from cancer treatment. Geriatric assessment with management should be integrated into the clinical care of older patients with advanced cancer and ageing-related conditions. FUNDING National Cancer Institute.

Abstract
Abstract
Background: With advances in next generation sequencing (NGS) and now approved targeted therapy in breast cancer, genomic testing to identify potentially actionable mutations has become a common practice in patients (pts) with advanced breast cancer using both ctDNA and traditional tissue-based assays. Less is known regarding physician practice patterns in obtaining NGS testing and the practical implications of testing in older adults with breast cancer.Methods: Pts with advanced breast cancer underwent molecular profiling using a plasma-based ctDNA NGS assay (Guardant360® or Tempus®) between 5/2015 and 5/2020 at Siteman Cancer Center. Pts with advanced breast cancer who underwent genomic profiling using a tissue-based NGS assay (Tempus®) between 12/2017 and 5/2020 at this institution were also included. Clinicopathological histories were obtained from the medical record. Correlations were examined using a Fisher’s exact test.Results: During 5/15-5/20, 244 pts underwent ctDNA testing and 147 pts had a tissue-based NGS assay performed. There was no significant difference between the number of pts ≥ 65 years-old who underwent ctDNA testing (n=78, 32.0%) and tissue testing (n=37, 25.2%). There was no statistically significant difference between date of metastatic diagnosis and date of NGS testing between the older and younger cohorts. In pts who underwent tissue-based NGS testing, there was no significant difference between site of tissue tested (distant recurrence vs local) in the older and younger cohorts. The most common clinical managements following both ctDNA and tissue-based testing are presented in Table 1. Out of the 391 pts who underwent testing, 27 pts had both ctDNA and tissue-based NGS performed. Pts ≥ 65 were less likely to have both assays performed (n=3, 11.1%; p<0.05). In pts undergoing both assays, there were high concordance rates of ESR1 (81.5%) and PIK3CA (81.5%) mutations. Mean time between tissue and plasma collection for NGS testing in pts undergoing both assays was 356.4 days.
Conclusion: Older adults, who are typically less likely to be included in clinical trials, may still benefit from NGS to reveal potentially targetable mutations. It is reassuring in our cohort that older adults had ctDNA and tissue-based NGS performed at similar rates as part of standard of care treatment. The clinical management following NGS testing was also not significantly different in the older adult cohort. Older adults were less likely to have both tissue and ctDNA testing performed however, given the high concordance rates between tests, this may be less clinically relevant.

Abstract
In both human and murine systems, we have developed an adoptive cellular therapy platform against medulloblastoma and glioblastoma that uses dendritic cells pulsed with a tumor RNA transcriptome to expand polyclonal tumor-reactive T cells against a plurality of antigens within heterogeneous brain tumors. We demonstrate that peripheral TCR Vβ repertoire analysis after adoptive cellular therapy reveals that effective response to adoptive cellular therapy is concordant with massive in vivo expansion and persistence of tumor-specific T cell clones within the peripheral blood. In preclinical models of medulloblastoma and glioblastoma, and in a patient with relapsed medulloblastoma receiving adoptive cellular therapy, an early and massive expansion of tumor-reactive lymphocytes, coupled with prolonged persistence in the peripheral blood, is observed during effective therapeutic response to immunotherapy treatment.

Abstract
Painful chemotherapy-induced peripheral neuropathy (CIPN) is a debilitating and treatment-resistant sequela of many chemotherapeutic medications. Ligands of α2δ subunits of voltage-gated Ca channels, such as pregabalin, have shown efficacy in reducing mechanical sensitivity in animal models of neuropathic pain. In addition, some data suggest that pregabalin may be more efficacious in relieving neuropathic pain in subjects with increased sensitivity to pinprick. We hypothesized that greater mechanical sensitivity, as quantified by decreased mechanical pain threshold at the feet, would be predictive of a greater reduction in average daily pain in response to pregabalin vs placebo. In a prospective, randomized, double-blinded study, 26 patients with painful CIPN from oxaliplatin, docetaxel, or paclitaxel received 28-day treatment with pregabalin (titrated to maximum dose 600 mg per day) and placebo in crossover design. Twenty-three participants were eligible for efficacy analysis. Mechanical pain threshold was not significantly correlated with reduction in average pain (P = 0.97) or worst pain (P = 0.60) in response to pregabalin. There was no significant difference between pregabalin and placebo in reducing average daily pain (22.5% vs 10.7%, P = 0.23) or worst pain (29.2% vs 16.0%, P = 0.13) from baseline. Post hoc analysis of patients with CIPN caused by oxaliplatin (n = 18) demonstrated a larger reduction in worst pain with pregabalin than with placebo (35.4% vs 14.6%, P = 0.04). In summary, baseline mechanical pain threshold tested on dorsal feet did not meaningfully predict the analgesic response to pregabalin in painful CIPN.

Abstract
PURPOSE Pegylated liposomal doxorubicin (PLD) combined with bortezomib is an effective salvage regimen for relapsed refractory multiple myeloma (RRMM). Carfilzomib, a second-generation proteasome inhibitor, has clinical efficacy even among bortezomib-refractory patients. PATIENTS AND METHODS We performed a phase I/II trial of carfilzomib, PLD, and dexamethasone (KDD) with the primary endpoints being safety and efficacy (NCT01246063). Twenty-three patients were enrolled in the phase I portion and the MTD of carfilzomib was determined to be 56 mg/m2 (days 1, 2, 8, 9, 15, and 16) when combined with PLD (30 mg/m2 on day 8) and dexamethasone (20 mg on days 1, 2, 8, 9, 15, and 16). Seventeen additional patients were enrolled in the phase II portion. RESULTS KDD was determined to be well tolerated with the only common grade 3/4 nonhematologic adverse events of infection. Grade 3/4 hematologic toxicity included lymphopenia (63%), thrombocytopenia (40%), anemia (40%), and neutropenia (28%). In the cohort of patients treated at the MTD, where median prior therapies were 2% and 42% were refractory to bortezomib, the overall response rate was 83% (20/24) with 54% (13/24) having a very good partial response or better. The median progression-free survival was 13.7 months (95% CI, 5.0-21.7). CONCLUSIONS This trial is the first to report outcomes using a triplet regimen of high-dose carfilzomib. KDD was well tolerated and appears efficacious in RRMM. Additional study is needed to more precisely determine patient outcomes with this regimen and its utility compared with other carfilzomib containing salvage regimens.

Abstract
Purpose: Ras/MEK/ERK pathway activation is common in oral cavity squamous cell carcinoma (OCSCC). We performed a neoadjuvant (preoperative) trial to determine the biomarker and tumor response of OCSCC to MEK inhibition with trametinib.Experimental Design: Patients with stage II-IV OCSCC received trametinib (2 mg/day, minimum 7 days) prior to surgery. Primary tumor specimens were obtained before and after trametinib to evaluate immunohistochemical staining for p-ERK1/2 and CD44, the primary endpoint. Secondary endpoints included changes in clinical tumor measurements and metabolic activity [maximum standardized uptake values (SUVmax) by F-18 fluorodeoxyglucose positron emission tomography/CT), and in tumor downstaging. Drug-related adverse events (AE) and surgical/wound complications were evaluated.Results: Of 20 enrolled patients, 17 (85%) completed the study. Three patients withdrew because of either trametinib-related (n = 2: nausea, duodenal perforation) or unrelated (n = 1: constipation) AEs. The most common AE was rash (9/20 patients, 45%). Seventeen patients underwent surgery. No unexpected surgical/wound complications occurred. Evaluable matched pre- and posttrametinib specimens were available in 15 (88%) of these patients. Reduction in p-ERK1/2 and CD44 expression occurred in 5 (33%) and 2 (13%) patients, respectively.

Abstract
Abstract
Purpose: Ras/MEK/ERK pathway activation is common in oral cavity squamous cell carcinoma (OCSCC). To determine biomarker and clinical tumor response of MEK inhibition in patients with OCSCC, we performed a neoadjuvant window of opportunity trial in which the MEK inhibitor trametinib was administered before surgery (NCT01553851).
Patients and Methods: Patients with untreated Stage II-IV OCSCC were scheduled to receive trametinib 2 mg/day orally for 7-14 days prior to surgery (last dose 24 hours before surgery). Tumor specimens from the primary site obtained before and after trametinib underwent immunohistochemistry staining for p-ERK1/2 (a marker of Ras/MEK/ERK activation) and CD44 (a protein upregulated by ERK activation), which represented the primary endpoint. Secondary endpoints included comparison of changes in pre- and post-trametinib tumor measurement by clinical examination and in metabolic activity (SUVmax) by FDG-PET/CT (partial response: >25% reduction). Adverse events (AE) and surgical/wound complications were evaluated.
Results: Of the 20 enrolled patients, 17 (85%) completed the study as planned. Three patients withdrew from the study due to AE, two (nausea; duodenal perforation) related to trametinib and one (constipation) related to narcotics. The most common drug-related AE was mild rash (9/20 patients, 45%). Nineteen patients (95%) underwent surgery and neck dissection with no unexpected surgical/wound complications. Fifteen patients (75%) were evaluable for the primary biomarker endpoint. 5 (25%) patients either had insufficient pre- or post-treatment biopsies or did not complete the trial. Reduction in p-ERK1/2 expression occurred in 7/15 evaluable patients (47%), whereas a reduction in CD44 occurred in 3/15 (20%). Reduction in tumor size (median 40%, range -74 to +17%) assessed by clinical examination was observed in 12/17 (71%) evaluable patients, and partial metabolic tumor response assessed by FDG-PET/CT was observed in 5/13 (38%) patients.
Conclusions: Trametinib was safe to administer as a neoadjuvant treatment in patients with OCSCC and several patients displayed significant reduction in Ras/MEK/ERK pathway activation, and in clinical and metabolic tumor responses. Further exploration of trametinib response in OCSCC patients is warranted.

Abstract
Human papilloma virus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) is associated with a favourable prognosis, although approximately 20-25% of patients ultimately develop recurrent cancer. Most disease recurrence events appear within 3 years; however, long-term follow-up of reported studies are limited, and the risk of late recurrence is unknown. We present a case report of a patient who developed distant metastases of HPV-related SCC 11 years after initial diagnosis and treatment of HPV-related OPSCC. Late disease recurrence may occur after initial diagnosis of HPV-related OPSCC. This observation has implications on the appropriate duration of follow-up and surveillance of these patients.

Predicting geriatric falls following an episode of emergency department care: a systematic review. Acad Emerg Med 2014; 21:1069-82.

Abstract
BACKGROUND Falls are the leading cause of traumatic mortality in geriatric adults. Despite recent multispecialty guideline recommendations that advocate for proactive fall prevention protocols in the emergency department (ED), the ability of risk factors or risk stratification instruments to identify subsets of geriatric patients at increased risk for short-term falls is largely unexplored. OBJECTIVES This was a systematic review and meta-analysis of ED-based history, physical examination, and fall risk stratification instruments with the primary objective of providing a quantitative estimate for each risk factor's accuracy to predict future falls. A secondary objective was to quantify ED fall risk assessment test and treatment thresholds using derived estimates of sensitivity and specificity. METHODS A medical librarian and two emergency physicians (EPs) conducted a medical literature search of PUBMED, EMBASE, CINAHL, CENTRAL, DARE, the Cochrane Registry, and Clinical Trials. Unpublished research was located by a hand search of emergency medicine (EM) research abstracts from national meetings. Inclusion criteria for original studies included ED-based assessment of pre-ED or post-ED fall risk in patients 65 years and older with sufficient detail to reproduce contingency tables for meta-analysis. Original study authors were contacted for additional details when necessary. The Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2) was used to assess individual study quality for those studies that met inclusion criteria. When more than one qualitatively similar study assessed the same risk factor for falls at the same interval following an ED evaluation, then meta-analysis was performed using Meta-DiSc software. The primary outcomes were sensitivity, specificity, and likelihood ratios for fall risk factors or risk stratification instruments. Secondary outcomes included estimates of test and treatment thresholds using the Pauker method based on accuracy, screening risk, and the projected benefits or harms of fall prevention interventions in the ED. RESULTS A total of 608 unique and potentially relevant studies were identified, but only three met our inclusion criteria. Two studies that included 660 patients assessed 29 risk factors and two risk stratification instruments for falls in geriatric patients in the 6 months following an ED evaluation, while one study of 107 patients assessed the risk of falls in the preceding 12 months. A self-report of depression was associated with the highest positive likelihood ratio (LR) of 6.55 (95% confidence interval [CI] = 1.41 to 30.48). Six fall predictors were identified in more than one study (past falls, living alone, use of walking aid, depression, cognitive deficit, and more than six medications) and meta-analysis was performed for these risk factors. One screening instrument was sufficiently accurate to identify a subset of geriatric ED patients at low risk for falls with a negative LR of 0.11 (95% CI = 0.06 to 0.20). The test threshold was 6.6% and the treatment threshold was 27.5%. CONCLUSIONS This study demonstrates the paucity of evidence in the literature regarding ED-based screening for risk of future falls among older adults. The screening tools and individual characteristics identified in this study provide an evidentiary basis on which to develop screening protocols for geriatrics adults in the ED to reduce fall risk.

Abstract
PURPOSE We investigated the association between body mass index (BMI) at the time of multiple myeloma (MM) diagnosis and overall survival in a cohort of patients within the Veterans Health Administration system. We also evaluated the association between weight loss in the year prior to diagnosis and survival. PATIENTS AND METHODS Prospective analysis was performed on a retrospectively assembled cohort of 2,968 U.S. veterans diagnosed and treated for MM between September 1, 1999, and September 30, 2009, with follow-up information through October 22, 2011. Cox modeling controlling for patient- and disease-related prognostic variables was used to analyze the data. RESULTS Underweight patients (BMI <18.5 kg/m2) had increased mortality, whereas patients who were overweight (BMI 25-29.9 kg/m2) and obese (BMI ≥30 kg/m2) had lower mortality compared with healthy-weight patients (BMI 18.5-24.9 kg/m2). Weight loss ≥10% of baseline in the year before diagnosis was also associated with increased mortality and made the association between increased BMI and survival nonsignificant. CONCLUSION Disease-related weight loss may be an important and heretofore unknown indicator of poor prognosis in MM. Assessment of weight loss prior to MM diagnosis should become a standard component of the clinical history in patients with newly diagnosed MM. Further research may identify relationships between disease-related weight loss and currently used prognostic factors in MM, further defining the role of this clinical factor in prognostic stratification.

Abstract
BACKGROUND Complete response (CR) at the primary tumor site as assessed by clinical examination following induction chemotherapy with PF (cisplatin and 5-fluorouracil [5-FU]) is a favorable predictive factor for overall survival and disease control in patients with locally advanced squamous cell carcinoma of the head and neck. In most series, the rate of CR at the primary site after induction PF was 20% to 30%. This study evaluated the efficacy and feasibility of induction nab-paclitaxel and cetuximab given with PF (ACPF) followed by definitive chemoradiation (CRT) in a phase 2 trial. METHODS Patients with squamous cell carcinoma of the head and neck were treated with ACPF (nab-paclitaxel 100 mg/m(2) /week; cetuximab 250 mg/m(2) /week; cisplatin 75 mg/m(2) on day 1; 5-FU 750 mg/m(2) /day on days 1 through 3) every 21 days for 3 cycles followed by CRT (cisplatin 100 mg/m(2) on days 1, 22, and 43 of radiation therapy [RT]). CR at the primary tumor site after 2 cycles of ACPF was the primary endpoint. RESULTS Thirty patients were enrolled, of which 22 (73%) had large (T3/T4) primary tumors. The CR rate at the primary tumor site after 2 cycles of ACPF was 53% and the overall response rate was 100%. Twenty-nine (96%) patients completed 3 cycles of ACPF, 26 (90%) completed definitive RT per protocol, and 22 of the 27 evaluable patients (81%) received > 2 of the 3 planned doses of cisplatin with RT. The estimated 2-year overall and progression-free survival rates were 84% and 65%, respectively. CONCLUSIONS Induction ACPF resulted in a high CR rate (53%) at the primary tumor site even in large tumors and did not adversely affect delivery of definitive CRT. Further investigation of ACPF is warranted.

Abstract
B lymphocytes from tonsillar tissue of an asymptomatic HIV-1-seropositive subject were transformed with Epstein-Barr virus (EBV) and tested for the production of HIV-1-specific antibodies by ELISA, using purified HIV-1SF2.2F11, a monoclonal antibody derived from a transformed line, is of the IgG1 subclass and recognizes an epitope in the conserved region of the envelope transmembrane glycoprotein gp41, which is expressed on the surface of HIV-infected T cells. The antibody does not mediate the lysis of infected T cells in antibody-dependent cellular cytotoxicity (ADCC) assays and does not neutralize the infectivity of HIV-1SF2 or the homologous isolate HIV-1TT2.2F11 appears to be the first anti-gp41 human monoclonal antibody that enhances the infectivity of an HIV-1 strain (i.e., SF128A) in the absence of complement.
