ABSTRACT

OBJECTIVES: Patient preferences have the potential to influence the development of new treatments for locally advanced/metastatic urothelial carcinoma (la/mUC), and therefore we explored how patients with la/mUC value different attributes of first-line treatments. METHODS: An online preference survey and multidimensional thresholding (MDT) exercise were developed following a targeted literature review and qualitative interviews with physicians, patients with la/mUC, and their caregivers. Treatment attributes included two benefits (overall response rate [ORR], pain related to bladder cancer [scored 0-100; 100 being the worst pain possible]) and four treatment-related risks (peripheral neuropathy, severe side effects, mild to moderate nausea, mild to moderate skin reactions). A Dirichlet regression was used to estimate average preference weights. Marginal utility and the reduction in ORR that patients would accept in exchange for a 10-point decrease or a 10% decrease in other attributes were calculated. RESULTS: A total of 100 patients were recruited and self-completed the survey and MDT. Mean patient age was 64.9 years (standard deviation, 7.6), 54% were female, and 38% identified as white. All included treatment attributes had a statistically significant impact on preferences. Changes in ORR had the largest impact, followed by cancer-related pain and treatment-related risks. Patients were willing to accept an 8.4% decrease in ORR to reduce their pain level by 10 points or a 7.8% decrease in ORR to reduce the risk of peripheral neuropathy by 10%. For a 10% decrease in severe side effects, mild to moderate nausea, or skin reaction, patients would accept decreases in ORR of 5.5%, 3.7%, or 3.4%, respectively. CONCLUSIONS: Of the attributes tested, changes in ORR were most important to patients. Patients made tradeoffs between treatment attributes indicating that a lower ORR may be acceptable for an improvement in other attributes such as reduced cancer-related pain or the risk of treatment-related adverse events.

ABSTRACT

Recent advancements in next generation sequencing have allowed for genetic information become more readily available in the clinical setting for those affected by cancer and by treating clinicians. Given the lack of access to geneticists, medical oncologists and other treating physicians have begun ordering and interpreting genetic tests for individuals with cancer through the process of "mainstreaming". While this process has allowed for quicker access to genetic tests, the process of "mainstreaming" has also brought several challenges including the dissemination of variants of unknown significance results, ordering of appropriate tests, and accurate interpretation of genetic results with appropriate follow-up testing and interventions. In this editorial, we seek to explore the process of informed consent of individuals before obtaining genetic testing and offer potential solutions to optimize the informed consent process including categorization of results as well as a layered consent model.

ABSTRACT

Cardio-Renal-Metabolic (CaReMe) diseases, in the form of heart failure, chronic kidney disease and diabetes mellitus, justify prescription of multiple prognostically beneficial medications, specifically renin-angiotensin system inhibitors, mineralocorticoid receptor antagonists, and sodium-glucose co-transporter-2 inhibitors. Use of these medications is complicated by association with adverse effects, particularly acute kidney injury and hyperkalaemia. Balancing risk and benefit is a common dilemma in acute medicine, with increasingly frequent and complex treatment decisions. Physicians should contemplate adjustments to medications within the context of not just acute illness but also long-term benefit. In the setting of hyperkalaemia, potassium-binding medications can be utilised. At hospital discharge optimisation of therapy can be achieved through clear safety netting advice, scheduled biochemical follow-up, and planned clinical review.

ABSTRACT

IMPORTANCE: There is an increasing number of cancer 'survivors' and increasing research into supportive care. However, it is unknown how patterns of attention and citation differ between supportive and non-supportive cancer care research. We sought to estimate the engagement of high-impact studies of supportive compared to non-supportive cancer care papers. METHODS: In a cross-sectional review of top oncology journals (2016-2023), we reviewed studies examining supportive care strategies and a frequency-matched random sampling of studies on non-supportive interventions. We compared data on social engagement metrics, as represented by Altmetric scores and citations and funding status, by supportive care or non-supportive care articles. RESULTS: We found overall Altmetric scores were no different between articles that did not test supportive care and those that did, with a numerically higher score for supportive care articles (86.0 vs 102; p=0.416). Other bibliometric statistics (such as the number of blogs, number of X users, and the number of X posts) obtained from Altmetric did not differ significantly between the two groups. Non-supportive cancer care papers had a significantly higher number of citations than supportive cancer care papers (45.6 in supportive care vs 141 in non-supportive care papers; p<0.001). A greater proportion of non-supportive cancer care papers were also supported by pharmaceutical companies compared to supportive cancer care papers (54.2 % vs 15.3 %; p<0.001). CONCLUSION: Though social media engagement is similar between supportive and non-supportive cancer care papers in high-impact journals, there is a significant difference in support from pharmaceutical companies and the number of citations.

ABSTRACT

Immune checkpoint inhibitors (ICIs) have transformed cancer care. Recently, atezolizumab gained its first global approval in a subcutaneous (SC) formulation by the UK medicines regulator, being notable as the first time an FDA- and/or European Medicines Agency (EMA)-approved ICI has been licensed via this administration route. Here, we discuss this approval, other SC ICIs in development, and the benefits and challenges of this administration route, including potential implications for patient care.

ABSTRACT

Urachal cancer is a rare malignancy of the urachus that is treated with surgical resection if localized and systemic chemotherapy for metastatic disease. Circulating tumor DNA (ctDNA) is a single-stranded or double-stranded DNA released by tumor cells into the blood and harbored the mutations of the original tumor, shedding new light on molecular diagnosis and monitoring of cancer. We report a case of resected localized urachal cancer with clear surgical margins and negative lymph node dissection but elevated ctDNA that progressed to metastatic disease. We also highlight the possibility of using ctDNA levels to assist in adjuvant therapy.

ABSTRACT

Recent findings reported for the phase 3 EV-302 trial indicate a survival benefit from enfortumab vedotin plus pembrolizumab versus chemotherapy in metastatic urothelial carcinoma. We discuss several key points regarding post-protocol therapies, extending the duration of therapy, toxicity, and costs, all of which may have a bearing on how physicians and patients balance the benefit against the potential harms associated with this regimen.

ABSTRACT

There is a rising trend in the consumption of dietary supplements, especially among adults, with the purpose of improving health. While marketing campaigns tout the potential health benefits of using dietary supplements, it is critical to evaluate the potential harmful effects associated with these supplements as well. The majority of the scarce research on the potential harmful effects of vitamins focuses on the acute or chronic toxicities associated with the use of dietary supplements. Quality research is still required to further investigate the risks of long-term use of dietary supplements, especially the risk of developing cancers. The present review concentrates on studies that have investigated the association between the risk of developing cancers and associated mortality with the risk of dietary supplements. Such an association has been reported for several vitamins, minerals, and other dietary supplements. Even though several of these studies come with their own shortcomings and critics, they must draw attention to further investigate long-term adverse effects of dietary supplements and advise consumers and healthcare providers to ponder the extensive use of dietary supplements.

ABSTRACT

Recent studies have identified a previously uncharacterized protein C11orf53 (now named POU2AF2/OCA-T1), which functions as a robust co-activator of POU2F3, the master transcription factor which is critical for both normal and neoplastic tuft cell identity and viability. Here, we demonstrate that POU2AF2 dictates opposing transcriptional regulation at distal enhance elements. Loss of POU2AF2 leads to an inhibition of active enhancer nearby genes, such as tuft cell identity genes, and a derepression of Polycomb-dependent poised enhancer nearby genes, which are critical for cell viability and differentiation. Mechanistically, depletion of POU2AF2 results in a global redistribution of the chromatin occupancy of the SWI/SNF complex, leading to a significant 3D genome structure change and a subsequent transcriptional reprogramming. Our genome-wide CRISPR screen further demonstrates that POU2AF2 depletion or SWI/SNF inhibition leads to a PTEN-dependent cell growth defect, highlighting a potential role of POU2AF2-SWI/SNF axis in small cell lung cancer (SCLC) pathogenesis. Additionally, pharmacological inhibition of SWI/SNF phenocopies POU2AF2 depletion in terms of gene expression alteration and cell viability decrease in SCLC-P subtype cells. Therefore, impeding POU2AF2-mediated transcriptional regulation represents a potential therapeutic approach for human SCLC therapy.

ABSTRACT

Over the past five years (2019-2023), several new targeted therapies and immunotherapy has been approved in treating relapsed cervical, ovarian, and endometrial cancers. Concurrently, there has been growing recognition of financial toxicity associated with cancer care during this time period. As such, we reviewed FDA approvals from 2019 to 2013 and identified the following approvals in gynecologic oncology: pembrolizumab plus lenvatinib, pembrolizumab for recurrent endometrial cancer that is MSI-H/dMMR, tisotumab vedotin, dostarlimab as single-agent therapy, and dostarlimab plus chemotherapy. We focused on approvals for endometrial cancer, and conducted a cost-effectiveness analysis for combination options approved in treating recurrent or advanced endometrial cancer (i.e. pembrolizumab plus lenvatinib versus placebo; dostarlimab plus chemotherapy versus placebo), and found neither regimen was cost-effective at a willingness-to-pay of $100,000 per Equal Value of Life Years Gained (evLYG). While these costs may not necessarily be translated to an individual patient, these costs are absorbed by healthcare systems and insurance providers on a larger scale with downstream effects on individuals contributing to healthcare costs a whole.

ABSTRACT

BACKGROUND: Previous studies on Hispanic thyroid cancer cases show sex disparities and an increased prevalence of large tumor sizes and nodal involvement. Here, we characterized Hispanic thyroid cancer cases in California. METHODS: We identified thyroid cancer cases from 2010 to 2020 using the California Cancer Registry by sex, race/ethnicity, histology, TNM stage, tumor size, lymph node involvement, and Charlson comorbidity score. The age-adjusted incidence rate (AAIR) and age-adjusted mortality rate (AAMR) for all causes of death were calculated. A Cox proportional hazards regression analysis was performed to evaluate the mortality risk from all causes of death by race. RESULTS: Overall, 56,838 thyroid cancer cases were identified, including 29.75% in Hispanics. Hispanics had the highest female-to-male incidence rate ratio (IRR 3.54) and the highest prevalence of T3/T4 tumor size (28.71%), the highest N1 nodal status (32.69%), and the highest AAMR (0.79 per 100,000 people). After adjusting for demographic and tumor covariates, compared to non-Hispanic White people, Hispanic ethnicity, with an HR of 1.22 (95% CI 1.18-1.25, p < 0.0001), remained a significant independent contributor to mortality risk. CONCLUSIONS: Hispanics had the greatest female-to-male IRR ratio, a greater prevalence of advanced disease features at diagnosis, along with the highest AAMR and increased mortality risk despite adjustments for demographic and tumor covariates. Further investigation into other risk factors is needed.

ABSTRACT

BACKGROUND: Due to encouraging pre-clinical data and supportive observational studies, there has been growing interest in applying cardiovascular drugs (including aspirin, angiotensin-converting enzyme [ACE] inhibitors, statins, and metformin) approved to treat diseases such as hypertension, hyperlipidemia, and diabetes mellitus to the field of oncology. Moreover, given growing costs with cancer care, these medications have offered a potentially more affordable avenue to treat or prevent recurrence of cancer. We sought to investigate the anti-cancer effects of drugs repurposed from cardiology or anti-inflammatories to treat cancer. We specifically evaluated the following drug classes: HMG-CoA reductase inhibitors (statins), cyclo-oxygenase inhibitors, aspirin, metformin, and both angiotensin receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors. We also included non-steroidal anti-inflammatory drugs (NSAIDs) because they exert a similar mechanism to aspirin by blocking prostaglandins and reducing inflammation that is thought to promote the development of cancer. METHODS: We performed a systematic literature review using PubMed and Web of Science with search terms including "aspirin," "NSAID," "statin" (including specific statin drug names), "metformin," "ACE inhibitors," and "ARBs" (including specific anti-hypertensive drug names) in combination with "cancer." Searches were limited to human studies published between 2000 and 2023. MAIN OUTCOMES AND MEASURES: The number and percentage of studies reported positive results and pooled estimates of overall survival, progression-free survival, response, and disease-free survival. RESULTS: We reviewed 3094 titles and included 67 randomized clinical trials. The most common drugs that were tested were metformin (n = 21; 30.9%), celecoxib (n = 20; 29.4%), and simvastatin (n = 8; 11.8%). There was only one study that tested cardiac glycosides and none that studied ACE inhibitors. The most common tumor types were non-small-cell lung cancer (n = 19; 27.9%); breast (n = 8; 20.6%), colorectal (n = 7; 10.3%), and hepatocellular (n = 6; 8.8%). Most studies were conducted in a phase II trial (n = 38; 55.9%). Most studies were tested in metastatic cancers (n = 49; 72.1%) and in the first-line setting (n = 36; 521.9%). Four studies (5.9%) were stopped early because of difficulty with accrual. The majority of studies did not demonstrate an improvement in either progression-free survival (86.1% of studies testing progression-free survival) or in overall survival (94.3% of studies testing overall survival). Progression-free survival was improved in five studies (7.4%), and overall survival was improved in three studies (4.4%). Overall survival was significantly worse in two studies (3.8% of studies testing overall survival), and progression-free survival was worse in one study (2.8% of studies testing progression-free survival). CONCLUSIONS AND RELEVANCE: Despite promising pre-clinical and population-based data, cardiovascular drugs and anti-inflammatory medications have overall not demonstrated benefit in the treatment or preventing recurrence of cancer. These findings may help guide future potential clinical trials involving these medications when applied in oncology.
