Analysis of lung cancer measures of the National Cancer Network pilot study in Poland for potential improvement in the quality of advanced-stage lung cancer therapy.

Background: This study aimed to present the performance of the National Cancer Network's (NCN) pilot program in the Lower Silesian Voivodeship (southwestern province of Poland with a population of 2,9 million in 2019), to analyse measures describing lung cancer patients and to determine whether those measures can be used to improve the treatment outcomes of stage III and IV patients with lung cancer in Poland.

Methods: Three measures of the NCN pilot programme were analysed: "Percentage of patients with genetic and molecular testing for predictive factors", "Assessment of the completeness of a pathological examination", and "Percentage of stage III and IV cancer patients". As many as 2,218 patients with ICD-10-CM Diagnosis Code C34 were included in the NCN pilot program from 1 to 2019 to 31 December 2020, in the Lower Silesian Voivodeship. The scores of each measure were calculated quarterly by the Regional Coordinating Centre, Wroclaw Comprehensive Cancer Center, Wroclaw, Poland.

Results: Genetic and molecular testing among stage III and IV patients was performed in only 40% and 60% of patients, respectively. The incompleteness of histopathological examinations did not exceed 0.5%. Stage III and stage IV patients accounted for 37% and 35% of the analysed patients, respectively.

Conclusions: The NCN pilot program measures presented in this study appear to be highly sensitive, simple, and transparent tools to monitor the quality of lung cancer diagnosis and assess clinical staging in patients within a specific region. An increase in the proportion of stage III and IV patients who will undergo genetic and molecular testing in the era of modern drug therapies should result in improved treatment outcomes in this patient group. In the present analysis, the values of the main analysed measure, which evaluates the number of genetic and molecular tests for predictive factors for lung cancer, were subject to significant fluctuations during the pilot project. Both upwards and downwards trends were observed. Further analysis in the future is warranted to eliminate the unfavourable factors influencing the obtained values of the measure.
