Medical costs of lung cancer care in Japan during the first one or two years after initial diagnosis

A systematic review and meta-analysis of macrolides in the management of adult patients with asthma

BACKGROUND

The efficacy of macrolides in the management of asthma has been studied but remains controversial. We conducted a systematic review and meta-analysis of macrolides in the management of adult patients with asthma.

METHODS

Randomized controlled trials of macrolides used in adult patients with asthma were searched for in MEDLINE, EMBASE, PsycINFO, Cochrane Library, CINAHL, and Igaku Chuo Zasshi databases to evaluate the efficacy and safety of macrolides.

RESULTS

Seventeen reports with macrolide treatment durations ranging from 6 to 48 weeks were included. Macrolides did not reduce exacerbations requiring hospitalization, severe exacerbations, or rescue use of short-acting beta-2 agonist inhalers; improve lung function; decrease peripheral blood or sputum neutrophil counts; or decrease fractional exhaled nitric oxide compared to placebo. Macrolides statistically improved asthma control and quality of life but by less than the minimal clinically important difference. Peripheral blood eosinophil counts as well as serum and sputum eosinophilic cationic protein concentrations were significantly decreased with macrolides compared to placebo. The improvement of asthma symptoms and airway hyperresponsiveness varied by study. The safety profile of macrolides was comparable to that of placebo.

CONCLUSIONS

Although macrolides have some useful clinical aspects, there is not sufficient evidence to recommend their use in the management of adult patients with asthma.

Economic burden of lung cancer in Morocco: A cost of illness study

INTRODUCTION

Lung cancer is the most common cancer in men and the second most common cancer in women. It is associated with substantial economic impact in terms of direct and indirect costs. The main objective of this study is to estimate the direct medical cost of lung cancer management in Morocco MATERIALS AND METHODS: A cost-of-illness study was conducted among patients treated at the Mohammed VI Center of Cancer (Casablanca) in 2019. The costs were estimated from the societal perspective using a bottom-up approach. The materials and procedures used were identified and quantified retrospectively from the information system and files. Their monetary value was calculated according to official prices published by the national health insurance agency. The horizon time adopted was 12 months.

RESULTS

The study included 271 patients, with an average age of 62.5 ± 9.5 years. Of these, 93.4 % were men and 92.1 % were former smokers. In terms of cancer staging, 68.3 % of patients were in stage IV while 28.8 % were in stage III. Adenocarcinoma was present in 43.5 % of cases. Patients underwent an average of 10.6 ± 5.1 radiological investigations, 56.1 ± 30.9 biological tests, and 24.1 ± 11.7 consultations. The average direct medical cost was 4455.3 USD (95 % CI: 4037.4-4873.2). Chemotherapy accounted for 19.9 % of the total cost, while radiological investigations and drugs accounted for 18.7 % and 17.6 %, respectively. Diagnostic tests and radiotherapy each accounted for 7.6 % of the total cost, while biological tests accounted for 7.5 % and hospitalizations accounted for 7.1 %. The cost was statistically higher in young patients (p = 0.017), in patients with adenocarcinoma (p < 0.0001), in patients with stage II tumor (< 0.00001), in patients who have undergone surgery (p = 0.002), chemotherapy (p < 0.0001), radiotherapy (p < 0.001) and in those without metastases (p < 0.0001).

CONCLUSION

These results provide evidence to support the ratification of the Framework Convention on Tobacco Control and the full adherence of the Kingdom of Morocco to the MPOWER measures.

Health Care Resource Use Among Patients with Advanced Non-Small Cell Lung Cancer in Japan, 2017-2019

Background

First-line immune checkpoint inhibitor (ICI) monotherapy for advanced non-small cell lung cancer (NSCLC) was introduced in Japan in February 2017. Limited information is available since that time regarding health care resource use for NSCLC in Japan, where the hospitalization burden is high.

Objective

We evaluated health care resource use from first- through third-line systemic anticancer therapy for patients with advanced NSCLC included in a multicenter, retrospective chart review study.

Methods

Eligible patients were aged 20 years or older with unresectable locally advanced/metastatic NSCLC with no known actionable genomic alteration who initiated first-line systemic anticancer therapy from July 1, 2017, to December 20, 2018, at 23 Japanese hospitals. We calculated the percentage of patients with a record of each resource used, the total number of each resource, and the resource use per 100 patient-weeks of follow-up from initiation of first-, second-, and third-line therapy, overall and by the 3 most common regimen categories, namely, ICI monotherapy, platinum-doublet chemotherapy (without concomitant ICI), and nonplatinum cytotoxic regimens (nonplatinum). Study follow-up ended September 30, 2019.

Results

Among 1208 patients (median age = 70 years; 975 [81%] men), 463 patients (38%) received ICI monotherapy, 647 (54%) received platinum-doublet chemotherapy, and 98 (8%) received nonplatinum regimens as first-line therapy. During the study, 621 (51%) patients initiated second-line, and 281 (23%) initiated third-line therapy. The majority of patients experienced ≥1 hospitalization (76%-94%) and ≥1 outpatient visit (85%-90%) during each therapy line. The number of hospitalizations increased from 6.5 per 100 patient-weeks in first-line to 8.0 per 100 patient-weeks in third-line. During first-line therapy, the number of hospitalizations per 100 patient-weeks were 4.8, 8.4, and 6.5 for patients receiving ICI monotherapy, platinum-doublet chemotherapy, and nonplatinum regimens, respectively, and the percentages of hospitalizations categorized as attributable to NSCLC treatment administration (no surgery, procedure, treatment of metastasis, or palliative lung radiation) were 64%, 77%, and 73%, respectively. The number of outpatient visits increased from 43.0 per 100 patient-weeks in first-line to 51.4 per 100 patient-weeks in third-line therapy. During first-line therapy, outpatient visits per 100 patient-weeks were 41.0, 46.7, and 33.0 for patients receiving ICI monotherapy, platinum-doublet chemotherapy, and nonplatinum regimens, respectively, and the percentages of outpatient visits for infusion therapy were 48%, 34%, and 36%, respectively.

Conclusions

The results of this study, although solely descriptive, showed differing patterns of health care resource use during first-line therapy among the 3 common systemic anticancer therapy regimens for advanced NSCLC in Japan and suggest that further research is needed to investigate these apparent differences by treatment regimen.
