Real-world treatment patterns in resectable (stages I-III) non-small-cell lung cancer: a systematic literature review

Aim: The aim of this systematic literature review was to describe treatment patterns in non-metastatic non-small-cell lung cancer. Methods: A search was conducted in MEDLINE and EMBASE. Eligible studies were multicentered (>50 patients) and conducted after 2000 in North America, Europe and Asia. Results: Twenty studies met the eligibility criteria. Based on US and Canadian studies in the resectable population, the proportion of patients who received neoadjuvant chemotherapy/chemoradiotherapy and adjuvant chemotherapy/chemoradiotherapy increased with increasing stage (i.e., from <3% in stage I to about 40% in stage III and from 15% in stage I to 30% in stage III, respectively). Within the resectable population, the breakdown between bimodal and trimodal therapy was variable, suggesting that clinical practice is not uniform. Conclusion: Overall, studies were heterogeneous, precluding data extrapolation across regions. Despite heterogeneity and limited evidence, this review suggested an increase in neoadjuvant and adjuvant chemotherapy with increasing stage, generally in line with treatment guidelines.

A microsimulation model to assess the economic impact of immunotherapy in non-small cell lung cancer

Introduction

Immunotherapy has become the standard of care in advanced non-small cell lung cancer (NSCLC). We aimed to quantify the economic impact, in France, of anti-PD-1 therapy for NSCLC.

Methods

We used patient-level data from the national ESCAP-2011-CPHG cohort study to estimate time to treatment failure and mean cost per patient for the four label indications approved by the European Medicines Agency (EMA) for NSCLC in May 2018. To compute the budget impact, we used a microsimulation model to estimate the target populations of anti-PD-1 therapy over a 3-year period, which were combined with the annual cost of treatment.

Results

Overall, 11 839 patients with NSCLC were estimated to be eligible for anti-PD-1 therapy 3 years after the introduction of anti-PD-1 therapies. The mean annual cost per patient in the control group ranged from €2671 (95% CI €2149–3194) to €6412 (95% CI €5920–6903) across the four indications. The mean annual cost of treatment for the four EMA-approved indications of anti-PD-1 therapy was estimated to be €48.7 million in the control group and at €421.8 million in the immunotherapy group. The overall budget impact in 2019 is expected to amount to €373.1 million. In the sensitivity analysis, flat doses and treatment effect had the greatest influence on the budget impact.

Conclusion

Anti-PD-1 agents for NSCLC treatment are associated with a substantial economic burden.

Metastatic NSCLC: Clinical, molecular, and therapeutic factors associated with long-term survival

BACKGROUND

Patients with metastatic non-small-cell lung cancer (NSCLC) who survive more than 2 years are considered long-term survivors (LTSs). The present study examined factors associated with long-term survival and collected information for future comparison.

METHODS

Clinical, molecular, and therapeutic data were collected from patients followed for primary stage IV (7th TNM classification) NSCLC within 2 years from diagnosis in the respiratory medicine departments of 53 French non-teaching hospitals. LTS and non-LTS records were compared. Factors associated with long-term survival were examined by univariate and multivariate analyses using logistic regression models.

RESULTS

Vital status at least 2 years after diagnosis was known for 1977 stage IV NSCLC patients; 220 (11.1%) were LTSs. On multivariate analysis, independent positive factors comprised: TTF-1(+) immunochemistry, EGFR-mutation, surgery, rescue radiotherapy, and targeted therapy. Independent negative factors comprised: prediagnosis weight loss>5kg, ECOG performance status>1, and primary radiotherapy.

CONCLUSIONS

Molecular biology and targeted therapy were decisive for long-term survival. With their development and their widespread implementation in clinical practice, the percentage of LTSs is expected to grow. Factors determining long-term survival found in this study should be taken into account when considering treatment options for patients with stage IV NSCLC.

Aerosol Immunotherapy with or without Cisplatin for metastatic lung cancer non-small cell lung cancer disease: In vivo Study. A more efficient combination

Lung cancer is the leading cause of cancer death after prostate cancer for males and breast cancer for females. There are novel therapies in the past five years such as; tyrosine kinase inhibitors and most recently in the last two years immunotherapy. Immunotherapy is currently being investigated if it can be administered alone or in combination. Previously we have investigated whether immunotherapy compounds can be produced as aerosols, and in the current study we investigated the safety and efficiency independently of the programmed death-ligand 1. The aerosol administration of both cisplatin and nivolumab is possible. The combination of the two drugs has a synergistic effect and therefore should be considered an option. Time of administration for immunotherapy is also very important.
