Assessment and prediction of glioblastoma therapy response: challenges and opportunities.

Glioblastoma is the most aggressive type of primary adult brain tumour. The median survival of patients with glioblastoma remains approximately 15 months, and the 5-year survival rate is <10%. Current treatment options are limited, and the standard of care has remained relatively constant since 2011. Over the last decade, a range of different treatment regimens have been investigated with very limited success. Tumour recurrence is almost inevitable with the current treatment strategies, as glioblastoma tumours are highly heterogeneous and invasive. Additionally, another challenging issue facing patients with glioblastoma is how to distinguish between tumour progression and treatment effects, especially when relying on routine diagnostic imaging techniques in the clinic. The specificity of routine imaging for identifying tumour progression early or in a timely manner is poor due to the appearance similarity of post-treatment effects. Here, we concisely describe the current status and challenges in the assessment and early prediction of therapy response and the early detection of tumour progression or recurrence. We also summarize and discuss studies of advanced approaches such as quantitative imaging, liquid biomarker discovery and machine intelligence that hold exceptional potential to aid in the therapy monitoring of this malignancy and early prediction of therapy response, which may decisively transform the conventional detection methods in the era of precision medicine.

A Preliminary Report on Quality of Life and Sexual Function in Brain Tumor Patients.

BACKGROUND: As tumor treatment has advanced, patients are surviving and returning to productive lives. Quality of life (QoL) has become a significant consideration in the care of survivors. The 2005 Institute of Medicine Cancer Survivorship Care Planning requires the inclusion of information on the possible effects of cancer on marital/partner relationship and sexual functioning, among other factors related to QoL. AIM: The purpose of this study is to explore the quality of life and the rates and types of sexual dysfunction among brain tumor patients. METHODS: Patients were recruited from a neuro-oncology practice and given a QoL questionnaire (FACT-Br). Women were given the Female Sexual Function Index (FSFI). Men were given scales to assess premature ejaculation (PE), erectile dysfunction (ED), and Peyronie's disease. In addition, information about the site and type of tumor and treatment (surgery, radiation, chemotherapy) was collected. Descriptive statistics, as well as T-tests and ANOVAs, were used to analyze the data. OUTCOMES: Study outcomes were obtained utilizing clinical cutoff scores for the sexual function questionnaires. RESULTS: Data were collected on 50 patients. The most common form of brain tumor in this sample was glioblastoma. The frontal lobe was the most common location of tumors. There was significantly more sexual dysfunction than previously reported, with 66% of the sexually active women meeting the criteria for total FSFI. Of the men who were sexually active, 60% reported some ED, and 80% reported PE. CLINICAL TRANSLATION: The current findings contribute to supporting the assertion that it is important for physicians to discuss with their cancer patients the issues related to sexual function. STRENGTHS & LIMITATIONS: A primary strength of this study is the utilization of validated assessments of sexual function. The primary limitation is the sample size, particularly for men. CONCLUSION: Our capacity to address the sexual function concerns of patients is dependent on our understanding of the types of difficulties encountered. This study contributes information about sexual function, a major contributor to QoL, in patients with brain tumor diagnosis and treatment. Boccia ML, Anyanda EI, Fonkem E.

Hormone-Dependent Tumors and Sexuality in the Neuro-Oncology of Women (N.O.W.): Women's Brain Tumors, Gaps in Sexuality Considerations, and a Need for Evidence-Based Guidelines.

PURPOSE OF REVIEW: While females make up almost 60% of all brain and spinal cord tumors in adults, guidelines that address women's issues in neuro-oncology are lacking. This review sheds light on two common women's issues in neuro-oncology. RECENT FINDINGS: Neuro-oncology providers are often faced with patient questions about fertility and pregnancy maintenance or prevention and typically respond with generic cancer chemotherapy recommendations, based on the paucity of evidence on the use of common neuro-oncology chemotherapies and pregnancy. While these remain important gap issues, there are several other poorly researched issues in the Neuro-Oncology of Women (N.O.W.) including recommendations around endogenous and iatrogenic hormone exposure and female sexuality in cancer. As a significant percentage of cancers are hormone-dependent, it is important to understand how changes in hormone levels impact tumor biology over the course of a woman's lifespan. Furthermore, greater attention should be given to the impact of tumors and tumor treatments on female sexuality. This article is intended to serve as an introduction to these two specific subjects within the vast expanse of N.O.W. subject matter.

Nucleolin Is a Functional Binding Protein for Salinomycin in Neuroblastoma Stem Cells.

The aim of this study is to illuminate a novel therapeutic approach by identifying a functional binding target of salinomycin, an emerging anticancer stem cell (CSC) agent, and to help dissect the underlying action mechanisms. By utilizing integrated strategies, we identify that nucleolin (NCL) is likely a salinomycin-binding target and a critical regulator involved in human neuroblastoma (NB) CSC activity. Salinomycin markedly suppresses NB CD34 expression and reduces CD34+ cell population in an NCL-dependent manner via disruption of the interaction of NCL with CD34 promoter. The elevated levels of NCL expression in NB tumors are associated with poor patient survival. Altogether, these results indicate that NCL is likely a novel functional salinomycin-binding target that exhibits the potential to be a prognostic marker for NB therapy.

Neurological presentations of intravascular lymphoma (IVL): meta-analysis of 654 patients.

BACKGROUND: Patients with intravascular lymphoma (IVL) frequently have neurological signs and symptoms. Prompt diagnosis and treatment is therefore crucial for their survival. However, the spectrum of neurological presentations and their respective frequencies have not been adequately characterized. Our aim is to document the spectrum of clinical symptoms and their respective frequencies and to create a clinical framework for the prompt diagnosis of IVL. METHODS: A comprehensive meta-analysis of 654 cases of IVL published between 1957 and 2012 was performed to provide better insight into the neurological presentations of this disease. Neurologic complications were mainly divided into central nervous system (CNS) and peripheral nervous system (PNS) presentations. RESULTS: There were no differences in occurrences of CNS IVL based on gender or geographic locations (Asian Vs non-Asian). However, most patients with CNS IVL were younger than 70 years of age (p < 0.05). Our limited data do not support the treatment efficacy of methotrexate. CNS symptoms were seen in 42% of all cases. The most common CNS complications identified were cognitive impairment/dementia (60.9%), paralysis (22.2%), and seizures (13.4%). PNS complications were seen in 9.5% of cases. Out of these, muscle weakness (59.7%), neurogenic bladder (37.1%), and paresthesia (16.1%) were the most common presentations. CONCLUSIONS: CNS complications are more common among IVL patients. Out of these, dementia and seizures outnumber stroke-like presentations.

The Spine is the Tree of Life: A Systematic Review and Meta-Analysis of the Radiographic Findings Related to Spinal Injuries in Athletes.

This review article explores spinal injuries in athletes participating in various sporting activities. It also highlights the various mechanisms of injuries that contribute to spinal injuries in each sport. Electronic databases such as PubMed, Cochrane Library, Web of Science, Embase, MEDLINE Ovid, and Google Scholar were searched for articles from 2000 to 2022 on spine injuries in sports and radiological studies discussing the various injury patterns among athletes. Studies were scoured in accordance with the inclusion criteria, and relevant data such as the number of participants, sporting activities, spine injuries, and outcomes were retrieved. Fifteen articles that met the inclusion criteria were included in the study. Cervical spine injuries are common in athletes who participate in contact sports such as football. Similarly, athletes in collision sports such as football, rugby, and hockey are likely to suffer stingers due to traction and compression injuries. Players engaged in such as soccer, baseball, and swimming, are likely to suffer from spondylolysis. Soccer players are more prone to multiple lesions compared to athletes in sports such as baseball because the sport involves training exercises such as jogging and running without kicking any ball. In swimmers, spondylolysis is common in breaststroke and butterfly styles since they involve repeated flexion and hyperextension of the lumbar spine. CT is essential for diagnosing spondylolysis as it demonstrates the lesions more accurately. Ice hockey is associated with a significant incidence of cervical spine injuries, mostly due to players being constantly checked/pushed from behind. Spine injuries are common in elite athletes across several sports. About 10% of spinal injuries in the United States result from sports activities. In diagnosing spine injuries, imaging modalities such as MRI, CT, or plain radiographs are essential. From a radiologist's perspective, these tests help immensely in deciding which treatment is required for a particular athlete or how the injury can be optimally managed. Achieving recovery from a specific spine injury usually depends on the kind of injury and the rehabilitation process the athletes undergo before returning to play.

Ethambutol toxicity exacerbating the phenotype of CMT2A2.

INTRODUCTION: CMT2A2 is associated with mutations in the mitofusin 2 gene, which encodes a protein involved in mitochondrial fusion. Ethambutol is an antimycobacterial agent associated with toxic optic neuropathies. Ethambutol-induced optic neuropathy occurs in patients with mutations in a related fusion gene, OPA1, which is responsible for autosomal dominant optic atrophy. METHODS: We describe a patient with CMT2A2 (MFN2 mutation: T669G, F223L) who developed accelerated weakness, vocal cord paralysis, and optic atrophy after receiving ethambutol. RESULTS: Deterioration began within months of initiating ethambutol therapy. After discontinuation of ethambutol, neurologic deterioration stabilized with subsequent improvement in visual fields. CONCLUSIONS: CMT2A2 is part of a group of genetic disorders which share an association with the process of mitochondrial fusion. This case shows that patients with CMT2A2, and possibly other mitochondrial fusion defects, may be uniquely susceptible to ethambutol-induced neurotoxicity. This has implications regarding the underlying pathophysiology of mitochondrial fusion defects.

Gender and racial disparities in the incidence and mortality of pancreatic cancer in Mississippi State from 2003 to 2019.

Background: In the United States, the incidence and prevalence of pancreatic cancer are well-established relative to the factors of gender and race. These rates can be seen to be dictated by biological, behavioral, socio-environmental, socioeconomic, and structural factors. This paper focused on the context of Mississippi, with a particular emphasis on racial and gender-linked mortality and incidence from 2003 to 2019. Methods: Data were obtained from the Mississippi Cancer Registry. Specific parameters that were focused upon included the data source in the form of all cancer incidents and cancer mortality, geography in terms of cancer coalition regions, cancer sites in the form of the digestive system as a category to which pancreatic cancer belongs, and the year, ranging from 2003 to 2019. Results: From the findings, the rates were more dominant in blacks than their white counterparts, suggesting racial disparity. Additionally, regardless of race, females exhibited lower rates compared to males. In the state, there were also marked geographical variations in disease incidence and mortality rates, with the Delta cancer coalition region faring the worst in terms of incidence rates for both races and genders. Conclusions: It was concluded that in Mississippi, being a black male poses the highest risk. In the future, certain additional factors that will need to be investigated as per their probable moderating role to inform the coining of health care interventions at the state level. They include lifestyle and behavioral factors, comorbidities, stage of disease, and geographical variations or remoteness.

Safety and Efficacy of Radiofrequency Ablation and Epidural Steroid Injection for Management of Cervicogenic Headaches and Neck Pain: Meta-Analysis and Literature Review.

Dysfunction of the cervical spine and its anatomical features, mostly innervated by the C1, C2, and C3 spinal nerves, can result in a secondary headache known as cervicogenic headache (CHA), mainly characterized by unilateral pain. The usefulness of pharmaceutical medications and physical therapy is currently the subject of scant literature. Interventional pain management techniques can be applied when conservative treatment is unsuccessful. This study looks at radiofrequency ablation (RFA) and epidural steroid injection (ESI) to identify their safety and efficacy in managing patients with cervicogenic headaches and neck pain. Three databases - PubMed, Cochrane CENTRAL Library, and Embase were searched, and 110 studies were identified. Nine screening processes were included for review and meta-analysis. Statistical evaluation was conducted through STATA version 17 (College Station, TX: StataCorp LLC) and effect measures were reported through random effects model risk ratios. The main subject of focus included three following outcomes: incidences of pain relief, degree and duration of pain, and incidences of adverse effects. The findings showed both interventions relieved pain by a factor of >50%, demonstrating a relative effects risk ratio of 1.45 (-0.50, 3.39) for RFA: pain relief, 84.76 (82.82, 86.69) RFA: adverse effects, and 19.46 (18.80, 20.11) ESI: pain relief at 95% confidence interval. The efficacy of RFA and ESI differ. Both interventions are effective in the reduction of cervicogenic headache pain intensity. However, their complication rates and pain duration are considerably different. With ESI, the headaches can still recur weekly, demanding the use of oral analgesics to deal with them. On the other hand, RFA has a low complication rate. Improving guidance from imaging technologies, RFA has the potential to be the most effective interventional treatment.

The Use of Cannabinoids in the Treatment of Inflammatory Bowel Disease (IBD): A Review of the Literature.

Around the world, about 15 to 40% of individuals with inflammatory bowel disease (IBD) rely on cannabis and cannabinoids to reduce the need for other medications, as well as increase appetite and reduce pain. Whereas more and more patients continue to report benefits accruing from cannabis and cannabinoid usage in IBD, agreement relative to the use of cannabis and its derivatives in IBD remains unclear. This paper reviewed the interplay between cannabinoid use and IBD disease treatment, remission, or symptom relief. The study was conducted from a systematic review perspective. It involved consulting literature from published original research articles, noting outcomes, and performing a meta-analysis to identify trends and draw conclusions. The selected articles were those that had been published in a 10-year period ranging between 2012 and 2022. The motivation was to ensure recency and also relevance to contemporary scientific research and clinical environment practices. Indeed, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework helped in answering the focal question of the investigation, which revolved around whether cannabinoids are beneficial to IBD treatment and to what extent. The aim of using this protocol was to ensure the satisfaction of the article exclusion and inclusion criteria, as well as ensure the utilization of articles directly contributing to the central subject under investigation. In the findings, it was established that on the one hand, cannabinoid usage in IBD treatment comes with promising results as reported in the majority of the selected studies which reported reduced clinical complications which were assessed using Mayo scores, Crohn's Disease Activity Index (CDAI) score, weight gain, enhanced patient health perception, Lichtiger Index and Harvey-Bradshaw Index or general wellbeing. On the other hand, cannabinoid use remains questionable because evidence of high quality is yet to surface vividly, especially in terms of the mode of administration and the appropriate dose. It is also notable that the findings were characterized by a state of high heterogeneity in terms of the study designs of the studies that were selected, disease activity indices, the duration of treatment by different scholarly researchers, the difference in the modes of administration of cannabinoid and cannabis by different researchers, variations in cannabis dosage, differences in the selected studies' inclusion criteria, and variations in their case definitions. The implication is that whereas the efficacy of cannabinoid use in IBD treatment was reported in most studies, outcome generalizability from the review was highly likely to be restricted. In the future, it is recommended that randomized controlled trials center, set universal parameters for IBD treatment using cannabis and cannabinoids to determine intervention safety and effectiveness as well as having homogenous outcomes that can be compared between different studies. In so doing, the appropriate dose and ideal mode of administration of cannabis and its derivatives might be discerned, ensuring relevance based on patient characteristics such as gender and age, as well as the appropriate administration mode and dose as per IBD symptom severity.

Endoscopic Gastric Sleeve: A Review of Literature.

For morbid obesity, one of the treatment options that have been deemed the most effective is bariatric surgery. Specifically, endoscopic sleeve gastrectomy (ESG) has emerged as one of the minimally invasive procedures for weight loss to be developed recently. In this procedure, there is the endoscopic placement of sutures in a quest to ensure reductions in the stomach volume. In this review, the main aim was to review the literature concerning ESG's efficacy and safety. Secondary sources of data were used and electronic databases were searched to identify articles focused on assessing the safety or efficacy of ESG. They included several databases such as Clinicaltrials.gov, Embase (Excerpta Medica Database), and MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online) to select relevant articles. Both the titles and abstracts of the articles were used to determine their inclusion or exclusion from the current review. Additionally, some keywords were used to search and obtain relevant articles such as: ESG, obesity, bariatric surgery, and total body weight loss. This review relied on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework for the identification of articles, screening, determination of eligibility, and inclusion and exclusion as deemed appropriate. From the findings, the review established that ESG is effective when used as an alternative intervention for obesity. The beneficial effects are felt particularly in terms of the procedure's capacity to ensure that the total body weight loss mean percentage is significant. Apart from the benefit of ensuring weight loss, ESG was also found to impair gastric emptying, pose metabolic effects that are key to controlling obesity-associated metabolic dysregulation, and the ability to increase satiety. However, the procedure was documented to yield a few adverse events in some studies. Some of the notable adverse events include pulmonary embolism, potential pneumoperitoneum, and possible post-procedure leak in the posterior aspect of the gastric fundus as sutures exert tension and also cause thin walls. Emerging as a minimally-invasive procedure, ESG is a cost-effective alternative through which weight loss can be achieved significantly in obese populations. It leads to a slowdown of gastric emptying, causes an increase in satiety, and leads to an improvement in the metabolic profile. Therefore, for obese individuals not undergoing bariatric surgery, ESG can be an ideal treatment option, including individuals in need of a bridge to surgery and also those diagnosed with moderate obesity. Overall, when it comes to the management of obesity, this review established that ESG provides a paradigm shift targeting existing therapeutic gaps.

Iatrogenic immunodeficiency-associated lymphoproliferative disorders of the central nervous system: a treatment paradox.

Background: Primary central nervous system lymphomas (PCNSLs) have historically had dismal survival rates until the advent of high-dose methotrexate (HD-MTX) based chemotherapy regimens. With increasing prevalence of autoimmune disease and development of new immunosuppressants, a genetically distinct entity known as iatrogenic immunodeficiency-associated lymphoproliferative disorder (LPD) has emerged. Many of these cases arise following methotrexate use, challenging feasibility of standard HD-MTX regimens. The aim of this study was to further characterize this disorder and determine the optimal management strategy. Methods: We describe a case of a 76-year-old female with iatrogenic immunodeficiency-associated PCNSL successfully treated with surgical resection followed by an antiviral and rituximab based regimen. We then performed a systematic literature review and identified 58 cases of non-transplant iatrogenic immunodeficiency-associated LPD involving the CNS. We used a linear probability statistical model to determine correlations with outcome. Results: Natalizumab was associated with EBV negative tumors (P = .023), and EBV positive tumors were associated with improved outcomes (P = .016). Surgical resection was associated with improved outcomes (P = .032), although limited by potential confounding effect. Antiviral treatment (P = .095), rituximab (P = .111), and stem cell transplant (SCT) (P = .198) showed a trend toward improved outcomes. The remaining treatments including methotrexate showed no improvement. Conclusion: We propose that surgical resection, rituximab, and antiviral treatment may be considered as an alternative to standard HD-MTX based regimens when managing iatrogenic immunodeficiency-associated LPD of the CNS. Further study through prospective cohort studies or randomized clinical trials is warranted.

Transcriptomic analyses of patient peripheral blood with hemoglobin depletion reveal glioblastoma biomarkers.

Peripheral blood is gaining prominence as a noninvasive alternative to tissue biopsy to develop biomarkers for glioblastoma (GBM); however, widely utilized blood-based biomarkers in clinical settings have not yet been identified due to the lack of a robust detection approach. Here, we describe the application of globin reduction in RNA sequencing of whole blood (i.e., WBGR) and perform transcriptomic analysis to identify GBM-associated transcriptomic changes. By using WBGR, we improved the detection sensitivity of informatic reads and identified differential gene expression in GBM blood. By analyzing tumor tissues, we identified transcriptomic traits of GBM blood. Further functional enrichment analyses retained the most changed genes in GBM. Subsequent validation elicited a 10-gene panel covering mRNA, long noncoding RNA, and microRNA (i.e., GBM-Dx panel) that has translational potential to aid in the early detection or clinical management of GBM. Here, we report an integrated approach, WBGR, with comprehensive analytic capacity for blood-based marker identification.

An expanded safety/feasibility study of the EMulate Therapeutics Voyager™ System in patients with recurrent glioblastoma.

Aim: The EMulate Therapeutics Voyager™ is a simple, wearable, home-use device that uses an alternating electromagnetic field to alter biologic signaling within cells. Objective: To assess the safety/feasibility of the Voyager in the treatment of recurrent glioblastoma (rGBM). Methods: In this study, patients with rGBM were treated with Voyager as monotherapy or in combination with standard chemotherapy at the Investigator's discretion. Safety was assessed by incidence of adverse events associated with the Voyager. Patients were followed until death. Results: A total of 75 patients were enrolled and treated for at least one day with the Voyager (safety population). Device-related adverse events were uncommon and generally did not result in interruption or withdrawal from treatment. There were no serious adverse events associated with Voyager. A total of 60 patients were treated for at least one month (clinical utility population). The median progression-free survival (PFS) was 17 weeks (4.3 months) in the Voyager only group (n = 24) and 21 weeks (5.3 months) in the Voyager + concurrent therapy group (n = 36). The median overall survival (OS) was 7 months in the Voyager only group and 9 months in the Voyager + concurrent therapy group. In patients treated with Voyager + concurrent therapy, the median OS for patients enrolled with their 1st or 2nd recurrence (n = 26) was 10 months, while in patients enrolled with their 3rd or 4th recurrence (n = 10) OS was 7 months. Conclusion: The data support the safety and feasibility of the Voyager for the treatment of rGBM. Further prospective study of the device is warranted. Trial Registration Number: NCT02296580 (ClinicalTrials.gov).

The Texas Immuno-Oncology Biorepository, a statewide biospecimen collection and clinical informatics system to enable longitudinal tumor and immune profiling.

A detailed understanding of the molecular and immunological changes that occur longitudinally across tumors exposed to immune checkpoint inhibitors is a significant knowledge gap in oncology. To address this unmet need, we created a statewide biospecimen collection and clinical informatics system to enable longitudinal tumor and immune profiling and to enhance translational research. The Texas Immuno-Oncology Biorepository (TIOB) consents patients to collect, process, store, and analyze serial biospecimens of tissue, blood, urine, and stool from a diverse population of over 100,000 cancer patients treated each year across the Baylor Scott & White Health system. Here we sought to demonstrate that these samples were fit for purpose with regard to downstream multi-omic assays. Plasma, urine, peripheral blood mononuclear cells, and stool samples from 11 enrolled patients were collected from various cancer types. RNA isolated from extracellular vesicles derived from plasma and urine was sufficient for transcriptomics. Peripheral blood mononuclear cells demonstrated excellent yield and viability. Ten of 11 stool samples produced RNA quality to enable microbiome characterization. Sample acquisition and processing methods are known to impact sample quality and performance. We demonstrate that consistent acquisition methodology, sample preparation, and sample storage employed by the TIOB can produce high-quality specimens, suited for employment in a wide array of multi-omic platforms, enabling comprehensive immune and molecular profiling.

Health Records Database and Inherent Security Concerns: A Review of the Literature.

The use of electronic health records (EHRs) has grown significantly in the past decade. Health information databases contain sensitive patient information, including their names and addresses, tests, diagnoses, treatment, and medical history. This information should be secured and protected from manipulation and fraudulent use by third parties. EHRs are expected to increase efficiency in healthcare delivery, improve healthcare quality, and relieve increased financial pressure. Despite these expected benefits, EHRs are potentially vulnerable to security concerns that may affect the confidentiality and privacy of patients' personal information. This paper presents a literature review of EHRs, factors that support the security and safety of health records, potential security breaches, and solutions to inherent security concerns. The study collects data through a systematic review of past studies that have addressed the topic of EHRs and security issues, and other relevant publications on EHR systems, and procedures that help safeguard health records databases. A total of 30 sources are analyzed for all pertinent information regarding security concerns of health records databases. These sources were obtained through an internet search on credible databases, including Google Scholar, PubMed, and CINAHL databases. The results of the current study reveal the perceived vulnerability of EHRs to security concerns, common security issues, the nature of these common security concerns, Health Insurance Portability and Accountability Act rules, provider responsibilities, and recommendations for reducing EHR security risks. This paper also reveals effective strategies such as privacy-protection awareness and staff training to enhance the security of health records databases.

Falling Trend in the Epidemiology of Gastric Cancer in Mississippi From 2003 to 2019: What Mississippi Got Right.

BACKGROUND: The aim of this study is to give insight into the falling trend in gastric cancer epidemiology in the state of Mississippi. The period in focus is between 2003 and 2019. The aim of this study is to uncover what the state got right and the implications for future healthcare. METHODOLOGY: The data for this study was collected from the Mississippi state cancer registry. The geographic locations in focus are the state's cancer coalition regions. The data is presented in tables and graphs, with descriptive and inferential statistical analysis. RESULTS: An assessment of the respective cancer coalition regions reveals a notable decline in gastric cancer incidence rates between 2003 and 2009. The areas where the state got right were found to include evaluation and surveillance, environmental, systems, and policy changes, treatment, survivorship, early detection, and prevention. CONCLUSION: Given that the state is predominantly rural, it is recommended that additional innovative approaches are explored and implemented, including telemedicine implementation to foster real-time services regarding community health education and dissemination or messaging about actions such as gastric cancer screening and the needed environmental changes such as nutrition guideline adherence.

Geographical Distribution of Pancreatic Cancer in the State of Mississippi by Incidence and Mortality From 2003 to 2019.

BACKGROUND: Pancreatic cancer can be a very debilitating disease. In the USA and around the world, pancreatic cancer is among the causes of cancer-related deaths. This study aims to highlight mortality and incidence rates of pancreatic cancer by geographic location. METHODS: The study area is the state of Mississippi with a targeted time period between 2003 and 2019. The Mississippi Cancer Registry is the source of data for this study. The subject under investigation was divided into two phases. The first phase involved analyzing data on the incidence rate while the second phase entailed data analysis of the pancreatic cancer mortality rate in Mississippi. In both phases, the focus was on three categories of geographic locations in Mississippi, which include public health districts, the regional cancer coalitions in the state, and the interplay between rural and urban locations. Descriptive and inferential statistical approaches with graphical techniques and tabulations were utilized in data presentation. RESULTS: The results of this study demonstrate there are variations in the incidence rates of pancreatic cancer by geographic location in Mississippi. In the data analysis of the Mississippi public health districts, the worst-hit areas include the rural communities in the rural-urban regional analysis, the Delta region among the cancer coalition regions, and the Central District (incidence rates) and North District (mortality rates). CONCLUSION: In Mississippi, there is a need for aggressive community-based participation and education. This approach will help improve screening and early detection of pancreatic cancer. Healthcare intake should be boosted and geared toward a reduction in mortality rates. To minimize disparities that eventually lead to differences in disease incidence and mortality from different locations, legislative and non-legislative authorities should advocate for equitable distribution of healthcare resources. An understanding of the geographic distribution of pancreatic cancer in a state will aid in the designation of specific primary prevention measures targeted in the worst-hit communities.

The Emergence of Virtual Tumor Boards in Neuro-Oncology: Opportunities and Challenges.

Background Virtual tumor board (VTB) platforms are an important aspect of cancer management. They enable easier access to a multidisciplinary team of experts. To deliver high-quality cancer care, it is necessary to coordinate numerous therapies and providers, share technical knowledge, and maintain open lines of communication among all professionals involved. The VTB is an essential tool in the diagnosis and treatment of brain cancer. For patients with glioma and brain metastases, multidisciplinary tumor board guidelines should guide diagnosis and therapy throughout the course of the illness. VTBs are an emerging resource across various cancer care networks in the United States. Methodology We performed a systematic search of all VTBs incorporating a platform designed for this specific role. We reviewed the records of the Genomet VTB, the Medical University of South Carolina (MUSC) VTB, and Xcures VTB. Summary data examined included the year of launch, demographics, characteristics of cases, average response time, advantages, and how they handle protected health information. Results Overall, 30% of VTBs examined were launched in 2017. All had a Health Insurance Portability and Accountability Act-compliant online environment. On a review of Xcures records, the median age of the female patients was 57 years and the median age of the male patients was 55 years. The data showed that 44% (4.4 out of every 10 patients) with a confirmed treatment chose the VTB integrated option. Overall, 76% of patients in the Xcures registry had primary central nervous system tumors, with at least 556 patients in the tumor registry which included 46% glioblastoma cases (96% primary, 4% secondary). In the MUSC VTB project, 112 thoracic tumor cases and nine neuro-oncology cases were reviewed. The tumor board met weekly, and the average response time was within 24 hours of case review and presentation. The Genomet VTB de-identifies all patient information; this is a virtual platform primarily focused on neuro-oncology cases. Cases involved a median of five specialists most commonly neuro-oncologists, neurosurgeons, radiation oncologists, molecular pathologists, and neuroradiologists. The case review revealed an age range of six months to 84 years (mean age = 44.5 years), with 69.6% males and 30.4% females, 43.5% glioblastomas, 8.7% adenocarcinomas, and 8.7% infratentorial tumors. The average response time observed in all cases was ≤24 hours. Conclusions VTBs allow for quicker expert analysis of cases. This has resulted in an accelerated number of cases reviewed with a shortened communication time. More studies are needed to gain additional insights into user engagement metrics.

Larotrectinib in NTRK Fusion-Positive High-Grade Glioneuronal Tumor: A Case Report.

Glioneuronal tumors are rare central nervous system tumors with heterogeneous histological and molecular features. While the majority are low grade, a small percentage can behave aggressively. Due to the rarity of these tumors, there is no consensus on how to treat high-grade glioneuronal tumors, and they are often managed similarly to glial tumors. With the advent of molecular profiling, management decisions are increasingly determined by molecular alterations in the tumor rather than the tumor type, which can be a useful approach for tumor types that do not have robust supportive clinical trial data due to low prevalence. We present a case of an 18-year-old patient with a high-grade glioneuronal neoplasm initially treated with craniospinal irradiation, vincristine, and cyclophosphamide. He presented eight years later with a recurrent tumor and was found to be positive for MEF2D-NTRK1 fusion. He was treated with surgical resection and postoperative intensity-modulated radiation therapy (IMRT; 55.8 Gy) with concurrent temozolomide, followed by the NTRK inhibitor larotrectinib. He achieved a radiographic response, with a decrease in residual enhancement and radiographic improvement over the course of treatment. He remained in clinical and radiographic remission for six months. This demonstrates the successful treatment of a high-grade glioneuronal NTRK fusion-positive tumor with larotrectinib, which has only been previously reported once in the literature.
