Measuring the indirect cost associated with advanced non-small cell lung cancer: a nationwide cross-sectional study in China

Cost-effectiveness of toripalimab plus chemotherapy versus chemotherapy as first-line treatment for advanced non-small cell lung cancer in China: a societal perspective

BACKGROUND

To investigate the cost-effectiveness of toripalimab plus chemotherapy versus chemotherapy alone for advanced non-small cell lung cancer (NSCLC) patients from a societal perspective.

METHODS

A partitioned-survival model estimated the costs and cost-effectiveness of toripalimab plus chemotherapy versus standard chemotherapy for advanced NSCLC over 20 years. Clinical data were derived from the CHOICE-01 trial, and cost and utility inputs were gathered from Yaozh.com, expert interviews, and a nationwide hospital-based survey. Costs were reported in 2022 US dollars, and outcomes included quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs), with a 5% discount rate was applied. Sensitivity, subgroup, and scenario analyses verified the robustness of results.

RESULTS

Toripalimab plus chemotherapy resulted in 3.048 QALYs and a total cost of $60,813, with an ICER of $19,066 per QALY gained, below China's 3 times GDP per capita threshold ($38,223). Robustness is confirmed through sensitivity, subgroup and scenario analyses.

CONCLUSIONS

Toripalimab plus chemotherapy is a cost-effective option for treatment-naive advanced NSCLC compared to chemotherapy alone, providing valuable evidence for clinical and reimbursement decision-making.

Preferences for public health insurance coverage of new anticancer drugs: a discrete choice experiment among non-small cell lung cancer patients in China

BACKGROUND

Ensuring equal access to affordable, high-quality, and satisfied healthcare for cancer patients is a challenge worldwide. Our study aimed to investigate preferences for public health insurance coverage of new anticancer drugs among non-small cell lung cancer (NSCLC) patients in China.

METHODS

We identified six attributes of new anticancer drugs and adopted a Bayesian-efficient design to generate choice scenarios for a discrete choice experiment (DCE). The one-on-one, face-to-face DCE was conducted in four cities in Jiangsu Province. The mixed logit regression model was used to estimate patient-reported preferences for each attribute. The interaction model was used to investigate preference heterogeneity.

RESULTS

Data from 486 patients were available for analysis. The most valuable attribute was the out-of-pocket cost if reimbursed (RI = 32.25%), followed by extension of overall survival (RI = 15.99%), and low incidence of serious side effects (RI = 14.45%). Patients had the highest willingness to pay for the comparative 9-month' extension of overall survival. Patients with advanced NSCLC were more likely to expect new anticancer drugs could improve HRQoL (p < 0.01) and require fewer out-of-pocket costs (p < 0.01). Older patients and patients with low income cared more about the out-of-pocket costs (p < 0.001).

CONCLUSION

Health insurance policymakers need to consider the affordability, comparative survival benefits, comparative safety, and comparative patient-reported outcomes of new anticancer drugs. The findings also highlight the need to ensure affordability for older patients, low-income patients, and patients with advanced cancer.

Factors influencing economic toxicity and coping strategies in lung cancer patients: A scoping review

Objective

A scoping review aims to identify the factors that contribute to economic challenges for lung cancer patients, as well as effective responses to these challenges. This review will help in identifying lung cancer patients at risk of financial difficulties, shaping health policies, and allocating healthcare resources effectively.

Data sources

This review includes both published and unpublished empirical studies.

Methods

Following the scoping review guidelines set forth by the Joanna Briggs Institute (JBI), we conducted searches in databases including Pubmed, Embase, OVID, Sinomed, Web of Science, Proquest, Wanfang, and CNKI from the establishment of the repository to February 2024. We organized and analyzed the included literature.

Findings

16 papers were included in the review. We extracted assessment tools, influencing factors, and responses to economic challenges faced by lung cancer patients from the included literature. The main assessment tools for economic challenges include COST, questionnaires, medical records, burden calculations, and other relevant tools. Factors influencing economic challenges in lung cancer patients mainly include age, occupation, insurance, education, treatment, disease duration, and income. Coping strategies for economic challenges in lung cancer patients primarily include institutional, technological, and managerial reforms, as well as public education and psychological interventions.

Conclusion

The prevalence of economic challenges faced by lung cancer patients is influenced by several complex factors. Healthcare professionals can develop screening tools and intervention protocols based on these influencing factors, providing a foundation for implementing targeted intervention programs for lung cancer patients at high risk of economic challenges.

Cost-Effectiveness of First-Line Atezolizumab versus Chemotherapy in Non-Small-Cell Lung Cancer Patients Ineligible for Platinum-Containing Regimens

Purpose

The IPSOS study provided evidence supporting the efficacy and tolerability of first-line atezolizumab compared to single-agent chemotherapy for non-small-cell lung cancer (NSCLC) patients ineligible for treatment with a platinum-containing regimen. This study aimed to assess the cost-effectiveness of atezolizumab specifically in this population, considering the perspective of the Chinese healthcare system.

Patients and Methods

In this analysis, a three-state Markov model was utilized. The survival data were derived from the IPSOS clinical trial. Direct medical costs and utility values were collected from national authoritative database and published literature. The primary outcomes were costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratio (ICER). To ensure the robustness of our model, both one-way and probabilistic sensitivity analyses were conducted.

Results

Atezolizumab monotherapy led to an increase in costs of $4139.23 compared to single-agent chemotherapy. Additionally, it resulted in a gain of 0.14 QALYs, leading to an ICER of $29,365.79 per QALY, which was below the willingness-to-pay threshold of $36,066 per QALY used in the model. One-way sensitivity analyses revealed cost of atezolizumab and utility of progressive disease (PD) as major influencing factors for ICER. Furthermore, probabilistic sensitivity analyses confirmed our base-case results.

Conclusion

From the perspective of the Chinese healthcare system, atezolizumab emerges as a cost-effective choice for the first-line treatment of NSCLC patients ineligible for platinum-based chemotherapy.

Cost-Effectiveness Analysis of Sintilimab Plus Chemotherapy in Advanced Non-Squamous Non-Small Cell Lung Cancer: A Societal Perspective

INTRODUCTION

The updated ORIENT-11 study demonstrated that sintilimab, when combined with chemotherapy, had promising survival advantage compared to standard chemotherapy alone in the first-line treatment for previously untreated, locally advanced or metastatic non-squamous non-small cell lung cancer (nsNSCLC). This study aims to evaluate the cost-effectiveness of sintilimab plus chemotherapy for advanced nsNSCLC from a Chinese societal perspective.

METHODS

A partitioned survival model with a embedded decision tree was developed to assess the economic value of sintilimab plus chemotherapy over a lifetime horizon. Clinical data was captured from the updated ORIENT-11 study, while costs, health productivity losses, and utility values were collected from a nationwide cross-sectional survey in tertiary hospitals across multiple provinces in China. The primary outcomes were measured using the metrics of quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICER). Costs and health outcomes were discounted at an annual rate of 5% per annum. Sensitivity analyses, including one-way and probabilistic sensitivity analyses, subgroup analyses, and scenario analyses, were performed.

RESULTS

Compared to standard chemotherapy, treatment with sintilimab plus chemotherapy incurred a mean total cost of $23,979 and gained 0.98 QALYs over the lifetime horizon, resulting in an ICER of $24,568 per QALY gained. The use of sintilimab accumulated direct non-medical costs of $9262 and indirect costs of $6780 over 16 years. Probabilistic sensitivity analyses showed an 84.2% probability of sintilimab plus chemotherapy being cost-effective at a threshold of three times China's per capita gross domestic product in 2022 ($38,201). The model was most sensitive to the discount rate of QALYs and costs, as well as the costs of pemetrexed, sintilimab, and subsequent therapy in progressive disease state. Subgroup analyses indicated favorable incremental net monetary benefits in all subgroups.

CONCLUSION

Sintilimab plus chemotherapy is a cost-effective first-line treatment therapy for advanced nsNSCLC in China when compared to standard chemotherapy. These findings, along with the improved progression-free survival and overall survival (OS) observed in ORIENT-11, support the use of this regimen in eligible candidates for advanced nsNSCLC.

A latent class analysis of resilience and its association with patient-reported symptoms in patients with esophageal cancer after esophagectomy

Purpose

To identify the latent classes of resilience in patients with esophageal cancer after esophagectomy and develop a deeper understanding of the association between these classes and patient-reported symptoms.

Background

China accounts for more than half of the global burden of esophageal cancer, and patients with esophageal cancer experience numerous symptoms that affect their quality of life and prognosis. Given that resilience is a key element that alleviates the progression of symptoms, it may represent a potential means of to enhancing cancer patients' physical and psychological well-being.

Methods

The study was implemented in the thoracic surgery departments of three tertiary hospitals in eastern China. The participants were patients who were still hospitalized after esophagectomy. Data were gathered by self-report questionnaires, and a latent class analysis was utilized to identify different categories of resilience among the patients.

Results

A total of 226 patients were recruited. The three classes of resilience identified included high strength and striving (53.5%), medium resilience but weak self-recovery (35.9%), and minimal tenacity and external support (10.6%). Patients with low income (OR = 12.540, p = 0.004) were more likely to be in the minimal tenacity and external support class. Patients without comorbidities (OR = 2.413, p = 0.013) and aged 66-70 years (OR = 4.272, p < 0.001) were more likely to be in the high strength and striving class. The patient-reported symptoms and symptom-related interference of patients after esophagectomy varied considerably among the three categories of resilience.

Conclusion

Accurate interventions should be devised and executed according to the features of each type of resilience in patients after esophagectomy to maximize intervention efficacy. These findings highlight the important role of precision nursing.

Measuring direct non-medical burden among patients with advanced non-small cell lung cancer in China: is there a difference in health status?

Objective

This study was conducted to estimate the direct non-medical cost of advanced non-small cell lung cancer (NSCLC) patients and explore whether its associated factors vary by health status.

Methods

Data were obtained from 13 centers in five provinces for patients with advanced NSCLC in China. The direct non-medical cost of patients since the patients were diagnosed with NSCLC included the cost of transportation, accommodation, meal, hired caregiving, and nutrition. We measured patients' health status by EQ-5D-5L instrument and divided them into good (≥0.75) and poor (<0.75) groups based on the utility score. A generalized linear model (GLM) was used to assess independent associations between statistically significant factors and non-medical financial burden in health status subgroups.

Results

Data from 607 patients were analyzed. The direct non-medical cost associated with advanced NSCLC since diagnosis was $2,951 per case ($4,060 in the poor health group and $2,505 in the other), with nutrition costing the most. GLM results showed that residence(Urban area vs. Rural area: -1.038, [-2.056, -0.02]), caregivers' occupation type (Farmer vs. Employee: -1.303, [-2.514, -0.093]), hospitalization frequency (0.077, [0.033, 0.12]), average length of hospital stay (0.101, [0.032, 0.17]), and pathological type (Squamous carcinoma vs. Non-squamous carcinoma: -0.852, [-1.607, -0.097]) were independent factors influencing direct non-medical cost in the poor health group. Among participants with good health status, residence (Urban area vs. Rural area: -0.621, [-1.005, -0.236]), marital status (Others vs. Married: 0.762, [0.035, 1.488]), patients' employment status, current caregiving time per day (more than 9 hours per day vs. less than 3 hours per day: 0.471, [0.134, 0.807]), duration of disease (0.015, [0.007, 0.024]), and hospitalization frequency (0.091, [0.068, 0.113]) were statistically associated factors.

Conclusion

The direct non-medical economic burden of advanced NSCLC patients in China is considerable and differs by health status. Strengthening accessibility for more effective therapies and early nutritional intervention to improve prognosis, and further promoting accessible care forms within relevant healthcare insurance coverage may be potentially feasible approaches to alleviate the direct non-medical economic burden for patients and their families.
