The prognosis of patients with glioblastoma (GBM) remains poor despite current treatments. Targeted therapy in GBM has been the subject of intense investigation but has not been successful in clinical trials. The reasons for the failure of targeted therapy in GBM are multifold and include a lack of patient selection in trials, the failure to identify driver mutations, and poor blood-brain barrier penetration of investigational drugs. Here, we describe a case of a durable complete response in a newly diagnosed patient with GBM with leptomeningeal dissemination and PTPRZ1-MET fusion who was treated with tepotinib, a brain-penetrant MET inhibitor. This case of successful targeted therapy in a patient with GBM demonstrates that early molecular testing, identification of driver molecular alterations, and treatment with brain-penetrant small molecule inhibitors have the potential to change the outcome in select patients with GBM.

BACKGROUND
In the KEYNOTE-590 study, first-line pembrolizumab plus chemotherapy provided statistically significant improvement in overall survival, progression-free survival, and objective response rate compared with chemotherapy, with a manageable safety profile in patients with advanced esophageal cancer. Prespecified health-related quality-of-life (HRQoL) outcomes are reported.
MATERIALS AND METHODS
Change from baseline to week 18 in the EORTC Quality of Life Questionnaire Core 30 (QLQ-C30) global health status/QoL (GHS/QoL) and QLQ-Esophageal cancer module (OES18) dysphagia, pain, and reflux scales were evaluated.
RESULTS
The HRQoL analysis included 730 patients who received treatment and completed ≥1 HRQoL assessment. Least squares mean (LSM) change from baseline to week 18 was similar between treatment groups for QLQ-C30 GHS/QoL and physical functioning and QLQ-OES18 reflux scales. The QLQ-OES18 dysphagia (LSM difference, -5.54; 95% CI, -10.93 to -0.16) and pain (LSM difference, -2.94; 95% CI, -5.86 to -0.02) scales favored pembrolizumab plus chemotherapy over placebo plus chemotherapy. Median time to confirmed deterioration (TTD) was similar between treatment groups for QLQ-C30 GHS/QoL and physical functioning and QLQ-OES18 dysphagia and reflux scales. Compared with chemotherapy, pembrolizumab plus chemotherapy prolonged median TTD, as seen on the QLQ-OES18 pain scale (HR, 0.69; 95% CI, 0.51 to 0.95).
CONCLUSION
The use of pembrolizumab plus chemotherapy maintained HRQoL at week 18 relative to baseline and was comparable with placebo plus chemotherapy. These HRQoL results together with published reports of efficacy, support the use of pembrolizumab plus chemotherapy as first-line therapy for advanced/metastatic esophageal cancer.

BACKGROUND
The National Cancer Institute-Children's Oncology Group Pediatric Molecular Analysis for Therapy Choice (MATCH) precision oncology platform trial enrolled children aged 1-21 years with treatment-refractory solid tumors and predefined actionable genetic alterations. Patients with tumors harboring alterations in DNA damage repair (DDR) genes were assigned to receive olaparib.
METHODS
Tumor and blood samples were submitted for centralized molecular testing. Tumor and germline sequencing were conducted in parallel. Olaparib was given twice daily for 28-day cycles starting at a dose 30% lower than the adult recommended phase 2 dose (RP2D). The primary endpoint was the objective response.
RESULTS
Eighteen patients matched (1.5% of those screened) based on the presence of a deleterious gene alteration in BRCA1/2, RAD51C/D, or ATM detected by tumor sequencing without germline subtraction or analysis of loss of heterozygosity (LOH). Eleven (61%) harbored a germline mutation, with only one exhibiting LOH. Six patients enrolled and received the olaparib starting dose of 135 mg/m2/dose. Two participants were fully evaluable; 4 were inevaluable because <85% of the prescribed dose was administered during cycle 1. There were no dose-limiting toxicities or responses. Minimal hematologic toxicity was observed.
CONCLUSION
Most DDR gene alterations detected in Pediatric MATCH were germline, monoallelic, and unlikely to confer homologous recombination deficiency predicting sensitivity to olaparib monotherapy. The study closed due to poor accrual.

BACKGROUND
Although family caregivers play a critical role in care delivery, research has shown that they face significant physical, emotional, and informational challenges. One promising avenue to address some of caregivers' unmet needs is via the design of digital technologies that support caregivers' complex portfolio of responsibilities. Augmented reality (AR) applications, specifically, offer new affordances to aid caregivers as they perform care tasks in the home.
OBJECTIVE
This study explored how AR might assist family caregivers with the delivery of home-based cancer care. The specific objectives were to shed light on challenges caregivers face where AR might help, investigate opportunities for AR to support caregivers, and understand the risks of AR exacerbating caregiver burdens.
METHODS
We conducted a qualitative video elicitation study with clinicians and caregivers. We created 3 video elicitations that offer ways in which AR might support caregivers as they perform often high-stakes, unfamiliar, and anxiety-inducing tasks in postsurgical cancer care: wound care, drain care, and rehabilitative exercise. The elicitations show functional AR applications built using Unity Technologies software and Microsoft Hololens2. Using elicitations enabled us to avoid rediscovering known usability issues with current AR technologies, allowing us to focus on high-level, substantive feedback on potential future roles for AR in caregiving. Moreover, it enabled nonintrusive exploration of the inherently sensitive in-home cancer care context.
RESULTS
We recruited 22 participants for our study: 15 clinicians (eg, oncologists and nurses) and 7 family caregivers. Our findings shed light on clinicians' and caregivers' perceptions of current information and communication challenges caregivers face as they perform important physical care tasks as part of cancer treatment plans. Most significant was the need to provide better and ongoing support for execution of caregiving tasks in situ, when and where the tasks need to be performed. Such support needs to be tailored to the specific needs of the patient, to the stress-impaired capacities of the caregiver, and to the time-constrained communication availability of clinicians. We uncover opportunities for AR technologies to potentially increase caregiver confidence and reduce anxiety by supporting the capture and review of images and videos and by improving communication with clinicians. However, our findings also suggest ways in which, if not deployed carefully, AR technologies might exacerbate caregivers' already significant burdens.
CONCLUSIONS
These findings can inform both the design of future AR devices, software, and applications and the design of caregiver support interventions based on already available technology and processes. Our study suggests that AR technologies and the affordances they provide (eg, tailored support, enhanced monitoring and task accuracy, and improved communications) should be considered as a part of an integrated care journey involving multiple stakeholders, changing information needs, and different communication channels that blend in-person and internet-based synchronous and asynchronous care, illness, and recovery.

PURPOSE
Eastern Cooperative Oncology Group (ECOG) performance status (PS) is a key clinical variable for cancer treatment and research, but it is usually only recorded in unstructured form in the electronic health record. We investigated whether natural language processing (NLP) models can impute ECOG PS using unstructured note text.
MATERIALS AND METHODS
Medical oncology notes were identified from all patients with cancer at our center from 1997 to 2023 and divided at the patient level into training (approximately 80%), tuning/validation (approximately 10%), and test (approximately 10%) sets. Regular expressions were used to extract explicitly documented PS. Extracted PS labels were used to train NLP models to impute ECOG PS (0-1 2-4) from the remainder of the notes (with regular expression-extracted PS documentation removed). We assessed associations between imputed PS and overall survival (OS).
RESULTS
ECOG PS was extracted using regular expressions from 495,862 notes, corresponding to 79,698 patients. A Transformer-based Longformer model imputed PS with high discrimination (test set area under the receiver operating characteristic curve 0.95, area under the precision-recall curve 0.73). Imputed poor PS was associated with worse OS, including among notes with no explicit documentation of PS detected (OS hazard ratio, 11.9; 95% CI, 11.1 to 12.8).
CONCLUSION
NLP models can be used to impute performance status from unstructured oncologist notes at scale. This may aid the annotation of oncology data sets for clinical outcomes research and cancer care delivery.

BACKGROUND
The COVID-19 pandemic has not only caused unprecedented distress in the community but has also resulted in significant physical and psychological exhaustion among healthcare workers (HCWs). This exhaustion could potentially lead to serious effects on our healthcare system.
OBJECTIVE
The aim of this study was to gain more insight on the effect of COVID-19 on burnout among oncologists and other healthcare professionals at a large academic center.
METHODS
A 10-minute electronic questionnaire was distributed to actively employed physicians, APRNs, and PAs affiliated with the University of Miami. The survey encompassed a range of personal and professional characteristics, including stress related to COVID-19.
RESULTS
The survey was distributed to a total of 739 HCWs, with 182 respondents (24.6%) completing the entire survey. The impact of the pandemic on these professionals included increased workload (59.5%), reduced leadership opportunities (32.2%), job insecurity (28.6%), and rescheduling of professional activities (22.2%). Out of the 182 respondents, 70 were primarily from the fields of Oncology and Palliative Care.
CONCLUSIONS
Several factors have contributed to increased physical and psychological stress among HCWs, such as extended working hours, sleep deprivation, job insecurity, the shift to telemedicine, the risk of contracting the virus and endangering their families, lack of childcare options, and the added pressure of homeschooling. This study serves as a foundation for more comprehensive research aimed at elucidating and guiding the development of wellness programs crucial for the overall well-being of HCWs.

BACKGROUND
With the improvement of cancer treatment methods and increased life expectancy of patients, the prevalence of second primary cancers has gradually increased.
CASE PRESENTATION
In the present study, the case was a 58-year-old man diagnosed with rectal adenocarcinoma and underwent chemotherapy and neoadjuvant radiotherapy 10 years ago. After 5 years, he underwent a lobectomy due to lung metastasis. At the research time, he presented with itching; in ERCP, a 16-millimeter hypoechoic lesion was detected, and an FNA biopsy was performed, indicating malignancy. The patient underwent Whipple surgery, and pathology revealed a well-differentiated neuroendocrine tumor. He was discharged in good general condition.
CONCLUSION
This article emphasized the necessity of early detection and diagnosis of second primary cancer, as well as acting as if it was primary cancer to treat.

BACKGROUND
We describe a case in which bilateral optic nerve infiltration and leukemic retinopathy were the initial signs of disease relapse in a patient with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph-ALL) with central nervous system (CNS) involvement.
CASE PRESENTATION
A 65-year-old Asian female with Ph-ALL in complete remission presented at our institution with symptoms of visual disturbance, central scotoma and pain with eye movement in both eyes for a 1-month duration. Ophthalmic examination revealed remarkable optic disc swelling with multiple flame-shaped peripapillary hemorrhages, retinal venous dilation and retinal hemorrhages in both eyes. She was subsequently referred to the treating oncologist and diagnosed with Ph-ALL relapse with multiple relapsed diseases involving the bone marrow and CNS. After intrathecal (IT) therapy, her visual acuity dramatically improved, and her leukemic infiltrates decreased.
CONCLUSIONS
To the best of our knowledge, this is the first case report of ALL relapse with CNS involvement presenting as bilateral optic nerve infiltration and leukemic retinopathy in an adult. Hence, we highlight the priority and sensitivity of ophthalmic examinations, as they are noninvasive methods for detecting leukemia relapse.

Review
The Revised Cardiac Risk Index (RCRI) and the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) preoperative risk assessment tools are the most widely used methods for quantifying the risk of major negative perioperative cardiac outcomes that a patient may face during and after noncardiac surgery. However, these tools were created to include as wide a range of surgical factors as possible; thus, some predictive accuracy is sacrificed when it comes to certain surgical subpopulations. In this review, we explore the various surgical oncology patient populations for whom these assessment tools can be reliably applied and for whom they demonstrate poor reliability.
