Support Through Remote Observation and Nutrition Guidance (STRONG), a digital health intervention to reduce malnutrition among pancreatic cancer patients: A study protocol for a pilot randomized controlled trial.

Background: Malnutrition is a common and distressing condition among pancreatic cancer patients. Fewer than a quarter of pancreatic cancer patients receive medical nutrition therapy (MNT), important for improving nutritional status, weight maintenance, quality of life and survival. System, provider, and patient level barriers limit access to MNT. We propose to examine the feasibility of a 12-week multi-level, digital health intervention designed to expand MNT access among pancreatic cancer patients. Methods: Individuals with advanced pancreatic cancer starting chemotherapy (N = 80) will be 1:1 randomized to the intervention or usual care. The Support Through Remote Observation and Nutrition Guidance (STRONG) intervention includes system-level (e.g., routine malnutrition and screening), provider-level (e.g., dietitian training and web-based dashboard), and patient-level strategies (e.g., individualized nutrition plan, self-monitoring of dietary intake via Fitbit, ongoing goal monitoring and feedback). Individuals receiving usual care will be referred to dietitians based on their oncologists' discretion. Study assessments will be completed at baseline, 4-, 8-, 12-, and 16-weeks. Results: Primary outcomes will be feasibility (e.g., recruitment, retention, assessment completion) and acceptability. We will collect additional implementation outcomes, such as intervention adherence, perceived usability, and feedback on intervention quality via an exit interview. We will collect preliminary data on outcomes that may be associated with the intervention including malnutrition, quality of life, treatment outcomes, and survival. Conclusion: This study will advance our knowledge on the feasibility of a digital health intervention to reduce malnutrition among individuals with advanced pancreatic cancer.

Safety and efficacy of anti-BCMA CAR-T cell therapy in older adults with multiple myeloma: A systematic review and meta-analysis.

INTRODUCTION: Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor T-cell (CAR-T) therapy is transforming the care of patients with relapsed/refractory multiple myeloma (MM). Unfortunately, despite being a disease of older adults these patients remain under-represented in most pivotal clinical trials. We performed a systematic review and proportion meta-analysis of prospective clinical trials and observational studies of anti-BCMA CAR-T therapy in patients with MM with the aim to determine the efficacy and safety of this therapy in older adults (≥65 years). MATERIALS AND METHODS: We searched the Pubmed, Scopus, Web of Science (WOS), Ovid, Embase, CENTRAL, and CINAHL databases through September 9, 2022 and abstracts from the American Society of Hematology (ASH) Annual Meeting 2022. Primary outcome measures included overall response rate (ORR), rates of cytokine release syndrome (CRS), and immune cell-effector-associated neurotoxicity syndrome (ICANS). study was registered with PROSPERO (study number: CRD42022334287). RESULTS: After screening 2218 references, 14 studies were included for data extraction, with a total of 558 patients, 26.2% (n = 146) of whom were older adults. The pooled ORR amongst this population was 93%, which was comparable to the ORR of 86% amongst younger patients. In older adults, the rates of CRS (any grade) and grade ≥ 3 were 95% and 21%, respectively. For younger patients, the pooled rate of CRS (any grade) and grade ≥ 3 CRS was 91% and 20%, respectively. The rate of ICANS (any grade) in older adults was 15%, which was higher than that observed in those <65 years. CONCLUSION: Older adults experience comparable outcomes to younger patients with anti-BCMA CAR-T therapy, albeit with numerically higher rates of neurotoxicity.

Simple Score of Albumin and CRP Predicts High-Grade Toxicity in Patients with Multiple Myeloma Receiving CAR-T Therapy.

Administration of chimeric-antigen receptor T-cell (CAR-T) therapy is complex and associated with unique toxicities. Identifying patients at risk for inferior outcomes is important for individualized management. The Glasgow-prognostic score (GPS) is a simple score shown to be highly prognostic of outcomes in the setting of traditional chemotherapy or checkpoint inhibitor administration. We sought to evaluate the value of the GPS to predict outcomes of patients with relapse refractory multiple myeloma (RRMM) receiving anti-BCMA CAR-T therapy. We included all patients treated with commercial CAR-T therapy for RRMM between 5/1/2021 and 2/1/2023 at the Moffitt Cancer Center. The GPS (CRP >1 mg/dL, 1 point; albumin <3.5, 1 point) was calculated for all patients at lymphodepletion (day -6) and patients were grouped as high-risk GPS (score = 2) or low-risk GPS (0 or 1). The primary endpoint was overall survival (OS) at day 100. A total of 139 pts were included, with a median follow-up of 6.7 months (95% CI, 6.2 to 8.9 months). Pts were treated with either idecabtagene vicleucel (83%) or ciltacabtagene autoleucel (17%). In total, 14% were classified with high-risk GPS, with significantly increased risk for grade 3 cytokine release syndrome (P = .003) and ICANS of any grade (P < .001). Patients in the high-risk GPS group had significantly lower day-100 OS (68.4% versus 97.3%, P < .001), OS at 6 months (56% versus 91.8% P = .0019) and PFS at 6 months (38.3% versus 72.3%, P = .03). The association of GPS with day-100 OS remained significant in a multivariable model. In conclusion, the GPS identifies a group of high-risk patients with RRMM receiving CAR-T therapy who experience increased rates of immune-mediated toxicity and are at higher risk for early mortality.

Elevation of cancer antigen 15-3 owing to oncocytic renal neoplasm in a patient without evidence of breast cancer recurrence on follow-up: a case report.

BACKGROUND: Cancer antigen 15-3 is a protein that clinicians commonly measure to monitor outcomes and response to treatment in patients with breast cancer. However, cancer antigen 15-3 can also be elevated in other, benign and malignant conditions. CASE PRESENTATION: A 73-year-old White woman with history of breast cancer presented to her primary care physician with right hip pain, and laboratory testing revealed elevated cancer antigen 15-3. Further workup with radiographic imaging revealed a large mass in her right kidney. The renal mass was subsequently removed, and the cancer antigen 15-3 level returned to normal. CONCLUSIONS: Elevation of cancer antigen 15-3 owing to causes other than breast cancer recurrence can be a potential diagnostic pitfall during a patient's follow-up. It is important for clinicians to be aware of the limitations of cancer markers and to utilize a combination of diagnostic tests for patient evaluation.

Oncogeriatric Developments.

Cancer is a disease of aging and is rapidly becoming the number one cause of mortality in older people. Over their lifetime, one in two men and one in three women will develop a cancer, with half of the risk being beyond the age of seventy. Therefore, cancer is a problem frequently encountered by geriatricians. In this article, we review a few recent progresses that will be of interest to the geriatric community. First, we now have robust evidence that a comprehensive geriatric assessment and management change outcomes in older cancer patients, notably allowing decreased treatment toxicity, better treatment completion, and increased functional outcomes. In gastrointestinal cancers and breast cancer, several recent studies have addressed when treatment intensity can be decreased, and when it cannot. New treatments for acute myeloid leukemia are finally beginning to improve outcomes for older patients and such patients should be referred to oncologists for management. In prostate cancer, new imaging techniques (e.g., PSMA scan) and treatment options can allow better treatment targeting and spare some hormonal and chemotherapy toxicity. Finally, we review recent public policy efforts to address the epidemiologic wave of cancer in older patients on a global scale.

Clinical trial knowledge among U.S. adults aged 65 years and up: Findings from a 2020 national survey.

BACKGROUND: Older adults are underrepresented in most clinical trials. As the United States observes growth in the number of older adults over time, it will be critical to include them in clinical trials to improve the generalizability of results across age groups. Although clinical trial participation requires clinical trial knowledge, no study has assessed clinical trial knowledge among older adults. Using a national survey, this study aims to identify the prevalence and determinants of clinical trial knowledge among older adults. METHODS: We used the 2020 Health Information National Trends Survey for secondary data analysis. We restricted the sample to older adults (aged 65 years and up). Our outcome variable was whether respondents reported having any clinical trial knowledge. We controlled for demographics, social determinants of health, healthcare utilization, and comorbidities through multivariable logistic regression models. RESULTS: Using a weighted sample of 27,574,958 adults, we estimated that 61.1% of older adults reported having at least some knowledge of clinical trials. After controlling for other factors, those with one to two (OR = 1.80, 95% CI:1.14-2.84) or three to five (OR = 2.93, 95% CI:1.74-4.95) portal visits compared with no portal visits, those with cancer (OR = 1.92, 95% CI:1.22-3.02), and those with depression (OR = 2.27, 95% CI:1.23-4.20) had greater odds of having clinical trial knowledge. Inversely, those with hypertension (OR = 0.62, 95% CI:0.42-0.92) had lower odds of clinical trial knowledge. CONCLUSIONS: Patient portal recruitment may be a supplemental intervention to improve clinical trial knowledge among older adults. Further research on additional interventions for identifying eligible participants is needed to minimize the burden among clinicians amidst other competing demands during clinic visits.

The Biological Process of Aging and the Impact of Ionizing Radiation.

Ionizing radiation is used to create models of accelerated aging because the processes of aging and radiation injury share common elements. In this chapter we review the biological processes of aging and the similarities and impact of ionizing radiation on those processes. The information draws on data from laboratory studies and from epidemiology studies of radiation exposure victims. The chapter reviews the effects of radiation on DNA, cells, and organs systems on aged adults. The science of aging and the effect of radiation on the aging process are areas of active research and our understanding is evolving.

Predictors of Toxicity Among Older Adults with Cancer.

An increasing number of cancer patients are of advanced age as the incidence of cancer increases with age. In this article, the clinical predictors of toxicity that may help in treatment selection are addressed, as well as mitigators of toxicity. The potential of artificial intelligence to enable further progress in the understanding of the interaction of age and tolerance to radiation is reviewed. The final section reviews the literature on patient-related outcomes for older patients.

Pre-operative Carboplatin/Paclitaxel Versus 5-Fluorouracil (5-FU)-based Chemoradiotherapy for Older Adults With Esophageal Cancer.

BACKGROUND/AIM: This study aimed to compare the efficacy and tolerability of pre-operative platinum/5-fluorouracil (P5F) and carboplatin/paclitaxel (CP), in combination with radiation therapy in older adults with locally advanced, stage I-III esophageal cancer. PATIENTS AND METHODS: We retrospectively reviewed 51 patients aged ≥70 years who underwent chemoradiotherapy followed by esophagectomy for stage I-III esophageal cancer between 2008 and 2018. Pathological complete response (pCR) and survival rates were compared across the two chemotherapy regimen arms. RESULTS: Treatment completion (p=0.28), pCR (p=0.89), and partial response rates were similar across both chemotherapy groups. Overall survival (OS) and disease-free survival (DFS) were similar across both groups with HR=0.80 (p=0.62) and HR=0.72 (p=0.72) respectively. CONCLUSION: The lesser toxic CP regimen may be used in older patients with locally advanced esophageal cancer, with tumor response and survival rates similar to P5F chemotherapy.

Exceptional response to Erlotinib monotherapy in EGFR Exon 19-deleted, KRAS wild-type, Chemo-refractory advanced pancreatic adenocarcinoma.

Advanced pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor with an abysmal prognosis. Beyond the first-line setting, treatment for advanced PDAC is limited and suboptimal. Also, the efficacy of epidermal growth factor receptor (EGFR) targeted therapy alone in the chemo-refractory setting in PDAC tumors harboring druggable EGFR mutations is unclear. Here we describe the case of a patient with chemo-refractory advanced PDAC with an activating exon-19 EGFR mutation who had an exceptional response to erlotinib monotherapy.

Update on the Role of Poly (ADP-Ribose) Polymerase Inhibitors in the DNA Repair-Deficient Pancreatic Cancers: A Narrative Review.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is the most common cancer found in the pancreas. It has a dismal prognosis and current therapeutic options, including surgical resection, provide only a temporary or limited response due to the development of treatment resistance. Methods: A narrative review of studies investigating poly (ADP-ribose) polymerase (PARP) pathway inhibitors in metastatic PDAC to highlight recent advances. Results: Mutations in BRCA genes confer a higher risk of PDAC, while germ line mutations are found in 4-7% of individuals harboring pancreatic cancer. Although solid tumors with defective DNA damage repair defect (DDR) genes such as BRCA show heightened sensitivity to platinum agents, tumors can exploit the PARP pathway as salvage pathways. Therefore, blocking this pathway will trigger cell death in vulnerable tumor cells with BRCA/DNA repair deficiency. Several drugs with inhibitory activity on the PARP pathway have been approved for breast and ovarian tumors harboring germ line or somatic BRCA mutations. Based on these results, the phase III POLO study showed a significant improvement in progression-free survival compared with placebo in BRCA mutant pancreatic tumors and highlighted the importance of germ line testing in everyone diagnosed with pancreatic cancer. In addition, expansion of the PARP inhibitor indication beyond BRCA mutations to other genes involved in DDR such as ATM and PALB2 merits attention. Conclusion: PARP inhibitors represent a safe and efficacious treatment for a subset of PDAC patients with BRCA mutations. Ongoing trials are evaluating PARP inhibitors in PDAC patients with non-BRCA DDR gene deficiencies as well as PARP inhibitors in combination with other agents, notably immune checkpoint inhibitors to expand the group of patients that derive benefit from this treatment.

Immuno-Oncotherapeutic Approaches in Advanced Hepatocellular Carcinoma.

Advanced hepatocellular carcinoma has limited treatment options, but there has been extensive growth recently with cabozantinib, regorafenib, lenvatinib, nivolumab, atezolizumab, and bevacizumab, which are some of the treatments that have received FDA approval just over the last three years. Because HCC tumor microenvironment is potentially immunogenic and typically characterized by inflammation, immunotherapy has been proposed as a potential novel therapeutic approach, which has prompted studies in advanced HCC patients investigating various immune-therapeutic strategies such as CAR-T cell therapy, checkpoint inhibitors, and onco-vaccines. The anti-PD-1 checkpoint inhibitors nivolumab and pembrolizumab have been FDA approved as a second line treatment in patients who progressed or are intolerant to Sorafenib. To build up on the success of PD-1 monotherapy, combinatorial regimens with PD-1/PD-L1 inhibitors plus VEGF targeted agents have shown positive results in various malignancies including HCC. The combination of atezolizumab plus bevacizumab is the new addition to the HCC treatment armamentarium following a pivotal study that demonstrated an improvement in OS over frontline sorafenib. Other novel immune-based approaches and oncolytic viruses are in the early phases of clinical evaluation. These innovative approaches enhance the intensity of cancer-directed immune responses and will potentially impact the outlook of this aggressive disease.

Immune Checkpoint Inhibitors versus VEGF Targeted Therapy as Second Line Regimen in Advanced Hepatocellular Carcinoma (HCC): A Retrospective Study.

Several targeted agents including multi-tyrosine kinase inhibitors (mTKIs) and immunotherapy (IO) agents have been approved for use beyond the frontline setting in patients with advanced hepatocellular carcinoma (HCC). Due to lack of prospective head-to-head comparative trials, there is no standardized way for alternating those agents beyond frontline. Therefore, we performed a retrospective review of the Kansas University (KU) cancer registry to determine whether IO may be superior to non-IO therapy. Patients with advanced HCC were divided into two groups based on the second-line systemic regimen received (IO vs. non-IO). Progression-free survival (PFS) and overall survival (OS) were calculated under the Kaplan-Meier and Cox proportional hazards models. No statistically significant differences in PFS and OS were found, although a non-significant delayed separation in the survival curve favoring IO was identified (median PFS 3.9 months vs. 3 months; median OS 10 months vs. 10 months respectively for IO vs. non-IO). This retrospective analysis is one of the earliest and largest studies comparing second-line IO and non-IO therapies thus far reported. Future studies should aim to define specific biomarkers for response prediction and treatment optimization based on individual patient and tumor characteristics. Furthermore, combinatorial therapeutic strategies is an evolving approach showing early promising signal.

Clinical Outcome of Ampullary Carcinoma: Single Cancer Center Experience.

INTRODUCTION: Ampullary cancers represent a subset of periampullary cancers, comprising only 0.2% all gastrointestinal cancers. Localized disease is primarily managed by a surgical intervention, called pancreaticoduodenectomy (PD), followed in many cases by the administration of adjuvant chemotherapy (CT) or chemoradiation therapy (CRT). However, there are no clear evidence-based guidelines to aid in selecting both the modality and regimen of adjuvant therapy for resected Ampullary carcinoma. METHODS: We retrospectively analyzed 54 patients at KU Cancer Center, who had undergone endoscopic resection or pancreaticoduodenectomy (PD) for Ampullary cancer from June 2006 to July 2016. We obtained patients' baseline characteristics, clinical presentation, pathology, treatment modality, recurrence pattern, and survival outcomes. The time-to-events data were compared using Kaplan-Meier methods. A univariate and multivariate Cox proportional hazards regression was performed to evaluate factors associated with overall survival (OS) and generate hazard ratios (HR). RESULTS: The mean age of the 54 patients was 68 (37-90). 38 (70%) were males and 16 (30%) were females. Most of the patients were Caucasian (76%). Approximately half of all patients had a history of smoking, 20% had alcohol abuse, and 13% had pancreatitis. Among the 54 patients with localized cancers, 9 (16%) were treated definitively with nonoperative therapies, usually due to a prohibitive comorbidity profile, performance status, or unresectable tumor. 45 out of 54 patients (83%) underwent surgery. Of the 45 patients who underwent surgery, 18 patients (40% of the study cohort) received adjuvant therapy due to concerns for advanced disease as determined by the treating physician. 13 patients (24%) received adjuvant CT and 5 patients (9.2%) received CRT. The remaining 27 patients (50%) underwent surgery alone. The median OS for the entire study cohort was 30 months. When compared to surgery alone, adjuvant therapy with either CT or CRT had no statistically significant difference in terms of progression-free survival (p=0.56) or overall survival (p=0.80). In univariate Cox proportional hazards regression analysis, high-risk features like peripancreatic extension (16%) and perineural invasion (26%) were found to be associated with poor OS. Lymph node metastasis (29%) did not significantly affect OS (HR 1.42, 95% CI [0.73-1.86]; p=0.84). Lymphovascular invasion (29%) was not associated with poor OS (HR 1.22, 95% CI [0.52, 2.96]; p=0.76). In multivariate Cox regression analysis, only age group>70 years was significantly associated with OS , while other factors, including the receipt of adjuvant therapy, lymph nodes, positive margin, and lymphovascular, perineural, and peripancreatic involvement, were not significantly associated with OS. These results are likely due to small sample size. CONCLUSIONS: Despite numerous advances in both cancer care and research, efforts in rare malignancies such as Ampullary cancer remain very challenging with a clear lack of an evidence-based standard of care treatment paradigm. Although adding adjuvant therapies such as chemotherapy or chemoradiotherapy is likely to improve survival in high-risk disease, there is no standardized regimen for the treatment of Ampullary cancer. More research is required to elucidate whether statistically and clinically relevant differences exist that may warrant a change in the current adjuvant treatment strategies.

Biologics, Immunotherapy, and Future Directions in the Treatment of Advanced Cholangiocarcinoma.

Gemcitabine plus cisplatin remains the standard first-line systemic therapy for advanced cholangiocarcinoma and offers a median survival of approximately 1 year. No standard regimens beyond the first line and no targeted or immunotherapy agents are approved yet in this disease. Development of molecular targeted therapy in this heterogenous and relatively rare malignancy continues to be a challenging area. The rapidly growing precision medicine efforts have uncovered the underlying mutational landscape of this lethal disease and paved the way for molecularly oriented clinical trials. The early results from such trials like those exploring IDH and FGFR2 derangements have highlighted its promising potential as alternative therapeutic options. Additionally, advances in cancer immunology have identified certain correlates as biomarkers of response to immune modulatory approaches. For instance, the presence of tumor DNA mismatch repair (MMR) deficiency and/or microsatellite instability (MSI), in 5% to 10% of cholangiocarcinoma, is associated with high rates and durability of responses to immune checkpoint blockade. Beside checkpoint inhibitors, other types of immune therapeutics like peptide and dendritic cell-based vaccines and adoptive cell therapies have been developed and are undergoing active evaluation in cholangiocarcinoma. With further research effort, the integration of tumor molecular profiling in trials exploring targeted immunotherapy will lead to better understanding of the predictive role of various molecular and immune biomarkers and ultimately shine the horizon for this patient population.

Factors associated with focal lamina cribrosa defects in glaucoma.

PURPOSE: To assess factors associated with focal lamina cribrosa (LC) defects in glaucoma. METHODS: Serial enhanced depth imaging (EDI) optical coherence tomography (OCT) B-scans of the optic nerve head were obtained from glaucoma patients. EDI OCT scans were reviewed for focal LC defects (laminar holes or disinsertions). Evaluated clinical factors included age, central corneal thickness, visual field (VF) mean deviation (MD), exfoliation syndrome, normal-tension glaucoma (NTG), disc hemorrhage, and intraocular pressure (IOP) during past follow-up. RESULTS: One hundred forty-eight glaucomatous eyes (148 patients; mean age, 68 ± 12 years; mean VF MD, -11.63 ± 6.96 dB) were included. Sixty-seven (45%) eyes had focal LC defects and 81 (55%) did not. Eyes with focal LC defects had a higher prevalence of both disc hemorrhage (25% vs. 6%) and NTG (33% vs. 9%) and worse VF MD (-14.12 vs. -9.58 dB) than those without focal LC defects (P = 0.002, P < 0.001, and P < 0.001, respectively). In the multivariate logistic regression analysis, higher frequency of disc hemorrhage detection (odds ratio [OR], 3.63; P = 0.032), a diagnosis of NTG (OR, 4.23; P = 0.005), and worse VF MD (OR, 1.11; P < 0.001) were significant factors associated with the presence of focal LC defects. Disc hemorrhage developed in the same half of the disc as the largest or the second largest focal LC defect in 15 of 17 eyes (88.2%). CONCLUSIONS: Disc hemorrhage, a diagnosis of NTG, and more advanced glaucoma status are associated with focal LC defects. Future studies are needed to elucidate the cause-and-effect relationships between focal LC defects and these factors.
