RESUMEN

There is significant racial disparity in thoracic malignancies in terms of epidemiology and outcomes. We analyzed race reporting and racial diversity in the registration trials of drugs approved by the FDA for thoracic malignancies from 2006 to 2020. We found a significant under-representation of non-white participants in FDA drug registration trials in thoracic malignancies. Furthermore, though almost all trials report some race information, FDA guidelines are not universally followed. There is a disproportionate disease burden of lung cancer in under-represented race communities, and clinical trials should prioritize racial diversity and inclusion efforts.

RESUMEN

This study investigates the occurrence of inflammatory vaginitis in women with Multiple Sclerosis (wwMS) undergoing B-cell depleting therapy versus other disease-modifying therapies (DMTs). Retrospective analysis of medical records from Stanford University between 2015-2023 shows similar rates of vaginitis in both groups, suggesting no significant association with B-cell therapy. Despite this, inflammatory vaginitis remains prevalent in both treatment groups, warranting further investigation into its mechanisms and management.

RESUMEN

BACKGROUND: Antipsychotic medications (APMs) and selective serotonin reuptake inhibitors (SSRIs) are frequently utilized in patients with neuroinflammatory disorders, such as autoimmune encephalitis and multiple sclerosis (MS). This retrospective study investigates how in-hospital treatment with APMs and SSRIs in patients with these neuroinflammatory diseases are associated with differences in hospital length-of-stay (LOS) and mortality. METHODS: We evaluated all the inpatients in the Stanford University Hospital from 2008 to 2023 diagnosed with either non-infectious encephalitis or MS and subdivided them into those who did or did not receive APMs or SSRIs while hospitalized. We then analyzed whether hospital LOS and mortality differed with these medications. RESULTS: Among inpatients with non-infectious encephalitis (n = 114), those who were exposed to APMs had a significantly increased mean LOS (11.8 vs 20.9 days, p < 0.01). For inpatients with MS (n = 1095), treatment with an APM was associated with a significant increase in mean LOS (2.8 vs. 7.1, p < 0.00001). When comparing typical to atypical APMs given to subjects with MS, those who received atypical APMs showed a significant increase in LOS (4.3 vs 10.5, p < 0.01), although typical APMs showed significantly increased risk of mortality (p < 0.05). For inpatients with MS and SSRI use, there was a significant increase in mean hospital LOS (3.5 vs 5.3, p < 0.01), with a significant difference found in those who received fluoxetine or citalopram, but not sertraline or escitalopram. Finally, several healthcare disparities were found, including that Black patients were more likely to receive APMs, and those with MS were more likely to receive typical rather than atypical APMs. Conversely, Black patients with MS were less likely to receive SSRI treatment. CONCLUSIONS: There was a statistically significant increase in LOS associated with APM use in non-infectious encephalitis and MS, as well as with SSRI use in MS. These data reflect the importance of these medications in these neuroinflammatory disorders and suggest that further investigation into their risks and benefits would be warranted.

RESUMEN

BACKGROUND: Microsatellite Instability (MSI) and Tumor Mutational Burden (TMB) are associated with immune checkpoint inhibitor (ICI) efficacy. We examined the association between TMB and MSI status with survival in patients with urothelial carcinoma (UC) treated with ICI. METHODS: Patients from 15 institutions were treated with ICI monotherapy. Primary endpoint was overall survival and secondary endpoints included observed response rate (ORR), and progression-free (PFS) calculated from ICI initiation. TMB was analyzed as dichotomous (≥10 vs. <10 mut/Mb) and continuous variable. RESULTS: We identified 411 patients: 203 were treated with ICI 1L/upfront; 104 with 2 + L. For the 1L/upfront: median [m] OS was numerically longer in patients with TMB ≥10 versus TMB <10: mOS 35 versus 26 months (HR = 0.6) and with MSI-H and MSI-S (mOS NR vs. 22 months), though neither association was statistically significant. A statistically significant association was found between TMB (continuous variable) and OS (HR = 0.96, P = .01). For 2 + L: mOS was numerically longer in patients with TMB ≥10 versus TMB <10: (20 vs. 12 months; HR = 0.9); mOS was 12 and 17 months for patients with MSI-H and MSI-S, respectively. Eighty-nine patients received maintenance avelumab (mAV): mOS was longer in patients with TMB ≥10 versus TMB <10: 61 versus 17 months; (HR = 0.2, P = .02) and with MSI-H and MSI-S (NR vs. 24 months). CONCLUSIONS: Although not reaching statistical significance in several subsets, patients with high TMB and MSI-H had numerically longer OS with ICI, especially with mAV. Further validation is needed.

RESUMEN

Bladder cancer is one of the most commonly diagnosed genitourinary malignancies. For many years, the primary treatment for metastatic urothelial cancer (mUC) was predicated on the use of platinum-based chemotherapy. More recently, immune checkpoint inhibitors (ICIs) were approved by regulatory agencies such as the US FDA for use in both the first- and second-line settings. This review outlines the approved ICIs for mUC in the second-line setting and as an alternative to chemotherapy in the first-line setting, as well as the novel agents that have also been incorporated into the treatment of this malignancy. Single-agent ICIs are often used in second-line settings in mUC, and there are three drugs currently approved for those who progress after receiving platinum-based chemotherapy. In the first-line setting, the preferred treatment regimen remains cisplatin-based chemotherapy. However, single-agent ICI can be an alternative first-line treatment for those who are not candidates for cisplatin-based therapy. There are also clinical trials adding ICIs to chemotherapy as combination regimens. However, treatment for mUC has now expanded even beyond immunotherapy. Newer targeted agents such as erdafitinib, a fibroblast growth factor receptor inhibitor, and two antibody-drug conjugates, enfortumab vedotin and sacituzumab govitecan, have been recently approved. As new drug agents are discovered, it will be important to assess both the treatment outcomes as well as the effects on patients' quality of life. Furthermore, integrating genetic and molecular information can help guide treatment decisions as next-generation sequencing is more commonly acquired during the evaluation of newly diagnosed patients with advanced and metastatic cancer.

RESUMEN

Immuno-oncology (IO) and targeted therapies, such as small molecule inhibitors, have changed the landscape of cancer treatment and prognosis; however, durable responses have been difficult to achieve due to tumor heterogeneity, development of drug resistance, and adverse effects that limit dosing and prolonged drug use. To improve upon the current medicinal armamentarium, there is an urgent need for new ways to understand, reverse, and treat carcinogenesis. Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein (Cas) 9 is a powerful and efficient tool for genome editing that has shown significant promise for developing new therapeutics. While CRISPR/Cas9 has been successfully used for pre-clinical cancer research, its use in the clinical setting is still in an early stage of development. The purpose of this review is to describe the CRISPR technology and to provide an overview of its current applications and future potential as cancer therapies.

RESUMEN

BACKGROUND: Treatment options for penile squamous cell carcinoma are limited. We sought to investigate clinical outcomes and safety profiles of patients with penile squamous cell carcinoma receiving immune checkpoint inhibitors. METHODS: This retrospective study included patients with locally advanced or metastatic penile squamous cell carcinoma receiving immune checkpoint inhibitors between 2015 and 2022 across 24 centers in the United States, Europe, and Asia. Overall survival and progression-free survival were estimated using the Kaplan-Meier method. Objective response rates were determined per Response Evaluation Criteria in Solid Tumours 1.1 criteria. Treatment-related adverse events were graded per the Common Terminology Criteria for Adverse Events, version 5.0. Two-sided statistical tests were used for comparisons. RESULTS: Among 92 patients, 8 (8.7%) were Asian, 6 (6.5%) were Black, and 24 (29%) were Hispanic and/or Latinx. Median (interquartile range) age was 62 (53-70) years. In all, 83 (90%) had metastatic penile squamous cell carcinoma, and 74 (80%) had received at least second-line treatment. Most patients received pembrolizumab monotherapy (n = 26 [28%]), combination nivolumab-ipilimumab with or without multitargeted tyrosine kinase inhibitors (n = 23 [25%]), or nivolumab (n = 16 [17%]) or cemiplimab (n = 15 [16%]) monotherapies. Median overall and progression-free survival were 9.8 months (95% confidence interval = 7.7 to 12.8 months) and 3.2 months (95% confidence interval = 2.5 to 4.2 months), respectively. The objective response rate was 13% (n = 11/85) in the overall cohort and 35% (n = 7/20) in patients with lymph node-only metastases. Visceral metastases, Eastern Cooperative Oncology Group (ECOG) performance status of 1 or higher, and a higher neutrophil/lymphocyte ratio were associated with worse overall survival. Treatment-related adverse events occurred in 27 (29%) patients, and 9.8% (n = 9) of the events were grade 3 or higher. CONCLUSIONS: Immune checkpoint inhibitors are active in a subset of patients with penile squamous cell carcinoma. Future translational studies are warranted to identify patients more likely to derive clinical benefit from immune checkpoint inhibitors.

RESUMEN

Numerous immunotherapeutic agents, such as immune checkpoint inhibitors (ICIs), have been approved for the treatment of genitourinary (GU) malignancies. While ICIs have improved treatment outcomes and expanded treatment options, they can cause immune-related adverse events (irAEs). The scope of irAEs is broad, and this paper aims to review the rheumatologic side effects associated with immunotherapy drugs approved for bladder cancer and renal cell carcinoma. IrAEs are graded by the common terminology criteria for adverse events (CTCAE), which ranges from 1 to 5. The management of irAEs includes corticosteroids or other immunosuppressive therapies, and it may require discontinuation of immunotherapy. Several real world experience studies suggest that most patients with pre-existing autoimmune diseases treated with ICI did not have to discontinue treatment due to immune-mediated side effects. While data suggest autoimmune side effects are manageable, patients with pre-existing autoimmune diseases are often excluded from immunotherapy clinical trials. Better understanding of these irAEs will improve its safety and expand its use in those with underlying autoimmune disease.

RESUMEN

PURPOSE: Patient-reported outcome measurements (PROMs) are increasingly used for cancer patients receiving active treatment, but little is known about the implementation and usefulness of PROMs in cancer survivorship care. This systematic review evaluates how cancer survivors and healthcare providers (HCPs) perceive PROM implementation in survivorship care, and how PROM implementation impacts cancer survivors' health outcomes. METHODS: We systematically searched PubMed/MEDLINE, Embase, CINAHL, Web of Science, and Cochrane Database of Systematic Reviews from database inception to February 2022 to identify randomized and nonrandomized studies of PROM implementation in cancer survivors. RESULTS: Based on prespecified eligibility criteria, we included 29 studies that reported on 26 unique PROMs. The studies were heterogeneous in study design, PROM instrument, patient demographics, and outcomes. Several studies found that cancer survivors and HCPs had favorable impressions of the utility of PROMs, and a few studies demonstrated that PROM implementation led to improvements in patient quality of life (QoL), with small to moderate effect sizes. CONCLUSIONS: We found implementation of PROMs in cancer survivorship care improved health outcomes for select patient populations. Future research is needed to assess the real-world utility of PROM integration into clinical workflows and the impact of PROMs on measurable health outcomes. IMPLICATIONS FOR CANCER SURVIVORS: Cancer survivors accepted PROMs. When successfully implemented, PROMs can improve health outcomes after completion of active treatment. We identify multiple avenues to strengthen PROM implementation to support cancer survivors.

RESUMEN

While localized penile cancers are typically treated surgically and metastatic penile cancers benefit from standard chemotherapy, there have been studies on the horizon demonstrating immunotherapy as a novel approach to metastatic penile cancers that have failed standard chemotherapy. We report a case series of two patients who improved on immunotherapy after progressing with standard chemotherapy regimens. The first case describes a 64-year-old male with a penile mass and significant lymphadenopathy who had surgical resection and adjuvant chemotherapy prior to continued disease progression. He was started on anti-EGFR treatment and improved initially, but he eventually had progression of disease. The second case describes a 79-year-old male with a penile mass who was treated with surgical resection and started on adjuvant chemoradiation, but he developed recurrence and nodal involvement. Therefore, second-line therapy of the PD-L1 inhibitor was started in this patient. There were no available clinical trials for penile cancer patients who progressed beyond the standard surgical therapy and chemotherapy.

RESUMEN

A 67-year-old male with past medical history of mantle cell lymphoma and atrial fibrillation presented with a truncal rash, bilateral lower extremity weakness, and confusion. Within three days of presentation, his condition rapidly deteriorated with the onset of diffuse flaccid paralysis, aphasia, and severe alteration in mental status. Initial results from serum studies, lumbar puncture, magnetic resonance imaging, and electroencephalogram were not diagnostic. However, on the ninth day after initial presentation, the West Nile Virus (WNV) immunoglobulin M antibody returned positive from the cerebrospinal fluid. West Nile Virus encephalitis is endemic worldwide, and is the most common viral encephalitis in the United States. WNV presents in a variety of ways, and the recognition by physicians is crucial due to the estimated 2-12% mortality rate and significant longterm morbidity of neuroinvasive disease. The initial management and long term prognosis are points of ongoing research. This case represents a particularly profound example of neuroinvasive WNV. Our patient made a significant recovery after his initial presentation with aggressive supportive care, however still suffers from bilateral lower extremity weakness more than a year later.

RESUMEN

The phosphoinositide 3 kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway is a well studied signaling pathway that regulates diverse cellular functions including proliferation, metabolism, and transcription. Aberrant activation of this pathway has been implicated in multiple cancers. Genomic studies have shown that activating mutations in oncogenes as well as inactivating mutations in tumor suppressor genes are present across a variety of malignancies, including urothelial carcinoma. In bladder cancer, up to 40% of tumors exhibit constitutive activation of the PI3K/AKT/mTOR pathway. Current treatments for non-muscle-invasive disease confer a 5-year cancer-specific survival rate as high as 90%. However, patients with muscle-invasive, recurrent, or metastatic disease have a poor prognosis. Although the introduction of immune checkpoint inhibitors is certainly changing the therapeutic landscape and is a great addition to the platinum-based therapy that was the standard of care for the past 3 decades, it is anticipated that a great number of patients would fail to respond or their disease would progress with either chemotherapy or immunotherapy. Therefore, the use of agents that target members of the PI3K/AKT/mTOR pathway represent an attractive, alternative therapeutic strategy for patients with advanced urothelial carcinoma. In this review we describe the pathway, with a focus on the rationale for targeting the PI3K/AKT/mTOR pathway in patients with advanced urothelial carcinoma and considers the challenges that we face from the current clinical trials. Novel agents such as PI3K inhibitors and microRNA inhibitors that target this pathway might lead to durable responses especially when used in combination with chemotherapy or immune checkpoint inhibitors, however, toxicity remains an obstacle. Finally, in this review we discuss the importance of developing biomarkers to help select appropriate patients and identify optimal treatment options.

RESUMEN

BACKGROUND: Angina pectoris (AP) is common in coronary artery disease (CAD), but whether those with diabetes mellitus (DM) experience AP as often as those without DM is unclear. HYPOTHESIS: AP prevalence is similar in those with vs without DM in a community sample with CAD. METHODS: In adults with CAD in the US NHANES 2001-2010, AP was determined by self-report and Rose questionnaire and compared by DM status. Physical functioning and medication use were also evaluated. RESULTS: Of 1957 adults with CAD, 619 (28.2%) had DM. Prevalence of AP was similar in those with vs without DM (48.9% vs 46.3%; P = 0.38). There was a trend toward more severe AP in those with glycated hemoglobin ≥7% (50.4%) vs <7% (27.1%; P = 0.09). Adjusted logistic regression showed a similar odds of AP (1.06, 95% CI: 0.84-1.33) in those with vs without DM, although among DM, a 2-fold greater odds of AP in women vs men. Physical functioning was worse in those with vs without AP overall (score of 25.9 vs 24.3; P < 0.001) and further diminished within those with comorbid DM (26.7 vs 24.0; P < 0.001). Among those with AP, those with vs without DM were more likely on ß-blockers, statins, angiotensin-converting enzyme inhibitors, and antiplatelet therapy. CONCLUSIONS: AP in CAD patients is similar among those with vs without DM, despite greater use of evidence-based therapies in DM patients. Greater physical limitations exist in those with vs without AP, and further diminish with comorbid DM.
