Cancer's Lasting Financial Burden: Evidence From a Longitudinal Assessment

High-Cost Cancer Drug Use in Medicare Advantage and Traditional Medicare

Importance

Medicare Advantage (MA) plans are designed to incentivize the use of less expensive drugs through capitated payments, formulary control, and preauthorizations for certain drugs. These conditions may reduce spending on high-cost therapies for conditions such as cancer, a condition that is among the most expensive to treat.

Objective

To determine whether patients insured by MA plans receive less high-cost drugs than those insured by traditional Medicare (TM).

Design, Setting, and Participants

This cohort study used data from the linked Colorado All Payer Claims Database and Colorado Central Cancer Registry. This population-based cohort included adults 65 years and older insured by Medicare with prescription coverage who reside in Colorado and were diagnosed with colorectal (CRC) or non-small cell lung cancer (NSCLC) between January 2012 and December 2021. The data were analyzed between December 2023 and August 2024.

Exposure

Enrollment in TM or MA insurance plans.

Main Outcomes and Measures

Claims for chemotherapy and oral targeted agents were identified. Thresholds for high-cost drugs were based on the distribution of drug costs. Inverse probability weighted logistic regression for receiving any cancer drug and for receiving a high-cost cancer drug was estimated, controlling for patient and ecological characteristics. The sample was stratified by cancer site and local/regional and distant stage.

Results

Of 4240 patients included in the analysis (mean [SD] age, 75 [7] years; 2327 [54.9%] female), 1991 were diagnosed with CRC and 2249 with NSCLC. A total of 1647 patients had local or regional CRC, and 344 had distant CRC; 1351 patients had local or regional NSCLC, and 898 had distant NSCLC. In the covariate-adjusted analysis, patients diagnosed with local or regional CRC who were insured by MA were 6.0 percentage points less likely to receive a cancer drug than similar patients insured by TM. Patients diagnosed with distant NSCLC were 10.0 percentage points less likely to receive a cancer drug if insured by MA. Among patients who received a cancer drug, patients insured by MA were less likely to receive a high-cost drug for local or regional CRC (by 10.0 percentage points) and distant CRC (by 9.0 percentage points).

Conclusions and Relevance

In this cohort study, high-cost drugs were more commonly prescribed among patients enrolled in TM and diagnosed with CRC. A similar pattern was not observed for patients with NSCLC, perhaps because clinical evidence suggests survival benefits to be associated only with certain drugs, all of which are expensive. Nonetheless, MA was modestly associated with reduced high-cost drug utilization and may reduce overall treatment costs.

Medicine availability and affordability for paediatric cancers, China

Objective

To investigate access to essential anticancer medicines for children throughout China.

Methods

We obtained cross-sectional drug use data for 2021 from 55 tertiary children's hospitals in seven geographical regions (one third of public children's hospitals in mainland China). Affordability was assessed by comparing the single-day copayment for each medicine with the same generic name and route of administration (i.e. product) or for a treatment course with daily disposable income per capita in each region. The median availability and affordability of all 33 anticancer medicines in the 2021 WHO Model list of essential medicines for children were calculated and compared by region and medicine type.

Findings

Although all medicines had been approved in China, 14 (42.4%) were available in under 50% of hospitals and six (18.2%) products had a median single-day copayment exceeding daily disposable income. Median availability was higher among the 19 medicines with approval for paediatric indications than among the 14 without (80.0% versus 48.2%, respectively; P < 0.001). Overall, 42.4% (14/33) of medicines had both good availability and affordability; the lowest proportion was in north-west China (30.3%, 10/33). A Chinese resident needed to work for 5.3 days to afford 4 weeks' induction therapy for acute lymphoblastic leukaemia, the most common childhood cancer.

Conclusion

Access to essential anticancer medicines for children remained suboptimal in China and varied across regions. Fewer than half the medicines studied had both good availability and affordability. Actions are warranted to address potential shortages and decrease the financial burden on families.

Estimating financial and health burden by initial Medicare plan choice and history of cancer

Understanding the downstream consequences of initial Medicare plan selection is necessary to ensure access to and affordability of health care services, especially for older adults with serious illness. We used 2008-2020 data from the Health and Retirement Study to estimate financial and health burden by initial Medicare plan selection (traditional Medicare without supplemental coverage, traditional Medicare plus supplemental coverage, or Medicare Advantage) and self-reported history of cancer. Initially choosing benefits with greater financial protections (either traditional Medicare plus supplemental coverage or Medicare Advantage) relative to traditional Medicare without supplemental coverage was associated with lower levels of out-of-pocket spending and a lower likelihood of reporting cost-related medication nonadherence and fair or poor health. Policymakers should consider improving the adequacy of traditional Medicare coverage to ensure the affordability of health care services and reduce the burden of serious illness among older adults, especially those with a history of cancer.

Diagnostic and prognostic role of microRNA-525 in different cancers: a systematic review and meta-analysis

Background

New prospect of cancer therapeutical management seems to be early diagnosis and prognosis prediction by microRNAs. The aim of our study is to explore the role of miR-525 in cancer diagnosis and prognosis through a systematic review and meta-analysis.

Methods

We conducted systematic search on PubMed, Embase, Web of Science, Scopus, Medline, Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases as at November 25, 2023, regardless of languages. Sensitivity, specificity, and diagnostic odds ratio (DOR) were extracted for diagnostic meta-analysis, while hazard ratio (HR) with 95% confidence interval (CI) for prognostic meta-analysis. Subgroup analysis and publication bias analysis were performed appropriately to investigate possible sources of heterogeneity.

Results

A total of 8 studies were included in the meta-analysis, of which 7 were used for diagnostic meta-analysis, covering 559 patients, and 3 were used for prognostic meta-analysis, covering 324 patients. The pooled sensitivity was 0.75 (95% CI: 0.70-0.79), specificity was 0.73 (95% CI: 0.68-0.78), DOR was 13.08 (95% CI: 4.18-40.91), and the area under the curve (AUC) was 0.86 (95% CI: 0.83-0.89). Subgroup analysis showed that miR-525 may have good diagnostic ability in the early tumor node metastasis (TNM) stage of cancer. Prognostic meta-analysis showed that low miR-525 expression in patients was associated with preferable survival (HR =0.17, 95% CI: 0.07-0.41).

Conclusions

Our findings suggest that miR-525 could be used as a potential biomarker for cancer patients. Low expression of miR-525 in cancers predicted a good prognosis.

Identification of symptom clusters and sentinel symptoms during the first cycle of chemotherapy in patients with lung cancer

PURPOSE

To identify symptom clusters (SCs) in patients with lung cancer who are undergoing initial chemotherapy and to identify the sentinel symptoms of each SC.

METHODS

A convenience sampling method was used to recruit patients with lung cancer who were undergoing their initial chemotherapy treatment. Patient information was collected using the General Demographic Questionnaire, MD Anderson Symptom Inventory (including the lung cancer module) and a schedule documenting the initial occurrence of symptoms. The Walktrap algorithm was employed to identify SCs, while sentinel symptoms within each SC were identified using the Apriori algorithm in conjunction with the initial occurrence time of symptoms.

RESULTS

A total of 169 patients with lung cancer participated in this study, and four SCs were identified: the psychological SC (difficulty remembering, sadness, dry mouth, numbness or tingling, and distress), somatic SC (pain, fatigue, sleep disturbance, and drowsiness), respiratory SC (coughing, expectoration, chest tightness, and shortness of breath), and digestive SC (nausea, poor appetite, constipation, vomiting, and weight loss). Sadness, fatigue, and coughing were identified as sentinel symptoms of the psychological, somatic, and respiratory SCs, respectively. However, no sentinel symptom was identified for the digestive SC.

CONCLUSION

Patients with lung cancer who are undergoing chemotherapy encounter a spectrum of symptoms, often presenting as SCs. The sentinel symptom of each SC emerges earlier than the other symptoms and is characterized by its sensitivity, significance, and driving force. It serves as a vital indicator of the SC and assumes a sentry role. Targeting sentinel symptoms might be a promising strategy for determining the optimal timing of interventions and for mitigating or decelerating the progression of the other symptoms within the SC.

Prehabilitation in Adults Undergoing Cancer Surgery: A Comprehensive Review on Rationale, Methodology, and Measures of Effectiveness

Cancer surgery places a significant burden on a patients' functional status and quality of life. In addition, cancer surgery is fraught with postoperative complications, themselves influenced by a patient's functional status. Prehabilitation is a unimodal or multimodal strategy that aims to increase a patient's functional capacity to reduce postoperative complications and improve postoperative recovery and quality of life. In most cases, it involves exercise, nutrition, and anxiety-reducing interventions. The impact of prehabilitation has been explored in several types of cancer surgery, most commonly colorectal and thoracic. Overall, the existing evidence suggests prehabilitation improves physiological outcomes (e.g., lean body mass, maximal oxygen consumption) as well as clinical outcomes (e.g., postoperative complications, quality of life). Notably, the benefit of prehabilitation is additional to that of enhanced recovery after surgery (ERAS) programs. While safe, prehabilitation programs require multidisciplinary coordination preoperatively. Despite the existence of numerous systematic reviews and meta-analyses, the certainty of evidence demonstrating the efficacy and safety of prehabilitation is low to moderate, principally due to significant methodological heterogeneity and small sample sizes. There is a need for more large-scale multicenter randomized controlled trials to draw strong clinical recommendations.

Perspectives, risk factors, and coping mechanisms in patients with self-reported financial burden following lung cancer surgery

OBJECTIVE

We evaluated self-reported financial burden (FB) after lung cancer surgery and sought to assess patient perspectives, risk factors, and coping mechanisms within this population.

METHODS

Patients with lung cancer resected at our institution between January 1, 2016, and December 31, 2021, were surveyed. Descriptive and multivariable analyses were performed to evaluate the association between clinical and financial characteristics with patient-reported major ("significant" or "catastrophic") FB.

RESULTS

Of 1477 patients contacted, 31.3% (n = 463) completed the survey. Major FB was reported by 62 (13.4%) patients. multivariable analyses demonstrated increasing age (odds ratio [OR], 0.92; 95% CI, 0.88-0.96), credit score >740 (OR, 0.29; 95% CI, 0.14-0.60), and employer-based insurance (OR, 0.24; 95% CI, 0.07-0.80) were protective factors. In contrast, an out of pocket cost greater than expected (OR, 3.63; 95% CI, 1.67-7.88), decrease in work hours (OR, 4.42; 95% CI, 1.59-12.25), or cessation of work (OR, 5.13; 95% CI, 2.06-12.78), chronic obstructive pulmonary disease diagnosis (OR, 5.39, 95% CI, 1.87-15.50), and hospital readmission (OR, 4.87; 95% CI, 1.11-21.42) were risk factors for FB. To pay for care, some patients reported "often" or "always" decreasing food (n = 102 [23.4%]) or leisure spending (n = 179 [40.7%]). Additionally, use of savings (n = 246 [62.9%]), borrowing funds (n = 72 [16.6%]), and skipping clinic visits (n = 36 [8.3%]) at least once were also reported. Coping mechanisms occurred more often in patients with major FB compared with those without (P < .001).

CONCLUSIONS

Patients with resected lung cancer may experience major FB related to treatment with several identifiable risk factors. Targeted interventions are needed to limit the adoption of detrimental coping mechanisms and potentially affect survivorship.

Profiles of financial toxicity and influencing factors among cancer patients: A latent profile analysis

BACKGROUND

While cancer treatment has improved patient prognosis, it has also become more costly. The high hospitalization expenses for cancer patients place a significant financial burden on individuals, families, and society.

OBJECTIVES

To identify the potential categories and characteristics of Financial Toxicity (FT) among cancer patients and explore the associated influencing factors.

METHODS

A cross-sectional study was conducted on 299 cancer patients in southwest China from February 2023 to May 2023(response rate 96.45 %). FT was measured by Financial Toxicity based on Patient-Reported Outcome Measures (COST-PROM), emotional inhibition was measured by the emotional inhibition scale (EIS), and treatment burden was measured by the Treatment Burden Questionnaire (TBQ). We used latent profile analysis (LPA) by Mplus.8.0 to identify latent classes of the FT. Multinomial logistic regression analysis was used to analyze the relevant factors on the different categories.

RESULTS

The FT of cancer patients can be identified into 3 groups: high-level (43.1 %), medium-level (36.1 %), and low-level (20.7 %) groups. Literacy, annual household income, health problem dimension scores, verbal inhibition scores, and self-control scores can be the predictors of FT among different profiles.

CONCLUSIONS

Our findings may provide a new viewpoint for managing FT among cancer patients. Healthcare providers should pay attention to the FT of cancer patients and develop targeted interventions to reduce their FT levels.

Are We Losing the Final Fight against Cancer?

Despite our increasing understanding of the biology and evolution of the cancer process, it is indisputable that the natural process of cancer creation has become increasingly difficult to cure, as more mutations are found with age. It is significantly more difficult to challenge the curative method when there is heterogeneity within the tumor, as it hampers clinical and genetic categorization. With advances in diagnostic technologies and screening leading to progressive tumor shrinkage, it becomes more difficult over time to evaluate the effects of treatment on overall survival. New treatments are often authorized based on early evidence, such as tumor response; disease-free, progression-free, meta-static-free, and event-free survival; and, less frequently, based on clinical endpoints, such as overall survival or quality of life, when standard guidelines are not available to approve pharmaceuticals. These clearances usually happen quite rapidly. Although approval takes longer, relative survival demonstrates the genuine worth of a novel medication. Pressure is being applied by pharmaceutical companies and patient groups to approve "new" treatments based on one of the above-listed measures, with results that are frequently insignificantly beneficial and frequently have no impact on quality of life.

Repurposing of neprilysin inhibitor 'sacubitrilat' as an anti-cancer drug by modulating epigenetic and apoptotic regulators

Modifications in the epigenetic landscape have been considered a hallmark of cancer. Histone deacetylation is one of the crucial epigenetic modulations associated with the aggressive progression of various cancer subtypes. Herein, we have repurposed the neprilysin inhibitor sacubitrilat as a potent anticancer agent using in-silico protein-ligand interaction profiler (PLIP) analysis, molecular docking, and in vitro studies. The screening of PLIP profiles between vorinostat/panobinostat and HDACs/LTA4H followed by molecular docking resulted in five (Sacubitrilat, B65, BDS, BIR, and NPV) FDA-approved, experimental and investigational drugs. Sacubitrilat has demonstrated promising anticancer activity against colorectal cancer (SW-480) and triple-negative breast cancer (MDA-MB-231) cells, with IC₅₀ values of 14.07 μg/mL and 23.02 μg/mL, respectively. FACS analysis revealed that sacubitrilat arrests the cell cycle at the G0/G1 phase and induces apoptotic-mediated cell death in SW-480 cells. In addition, sacubitrilat inhibited HDAC isoforms at the transcriptomic level by 0.7-0.9 fold and at the proteomic level by 0.5-0.6 fold as compared to the control. Sacubitrilat increased the protein expression of tumor-suppressor (p53) and pro-apoptotic makers (Bax and Bid) by 0.2-2.5 fold while decreasing the expression of anti-apoptotic Bcl2 and Nrf2 proteins by 0.2-0.5 fold with respect to control. The observed cleaved PARP product indicates that sacubitrilat induces apoptotic-mediated cell death. This study may pave the way to identify the anticancer potential of sacubitrilat and can be explored in human clinical trials.

Transcriptome and pan-cancer system analysis identify PM2.5-induced stanniocalcin 2 as a potential prognostic and immunological biomarker for cancers

Epidemiological studies have shown that air pollution and particulate matter (PM) are closely related to the occurrence of cancer. However, the potential prognostic and immunological biomarkers for air pollution related cancers are lacking. In this study, we proved PM2.5 exposure was correlated with lung cancer through transcriptome analysis. Importantly, we identified STC2 as a key gene regulated by PM2.5, whose expression in epithelial cells was significantly increased after PM2.5 treatment and validated by using RT-qPCR and immunofluorescence. Kaplan-Meier OS curves suggested that high STC2 expression positively correlated with a poor prognosis in lung cancer. Furthermore, we discovered that STC2 was associated with multiple cancers and pathways in cancer. Next, Pan-Cancer Expression Landscape of STC2 showed that STC2 exhibited inconsistent expression across 26 types of human cancer, lower in KIRP in cancer versus adjacent normal tissues, and significantly higher in another cancers. Cox regression results suggested that STC2 expression was positively or negatively associated with prognosis in different cancers. Moreover, STC2 expression was associated with clinical phenotypes including age, gender, stage and grade. Mutation features of STC2 were also analyzed, in which the highest alteration frequency of STC2 was presented in KIRC with amplification. Meanwhile, the effects of copy number variation (CNV) on STC2 expression were investigated across various tumor types, suggesting that STC2 expression was significantly correlated with CNV in tumors. Additionally, STC2 was closely related to tumor heterogeneity, tumor stemness and tumor immune microenvironment like immune cell infiltration. In the meantime, we analyzed methylation modifications and immunological correlation of STC2. The results demonstrated that STC2 expression positively correlated with most RNA methylation genes and immunomodulators across tumors. Taken together, the findings revealed that PM2.5-induced STC2 might be a potential prognostic and immunological biomarker for cancers related to air pollution.
