Introduction

On March 14, 2020, a general confinement was decreed in Spain due to the development of the COVID19 pandemic, affecting health care worldwide.
Objective: to measure the management of study times and the characteristics of patients with lung cancer studied in the Pneumology service of a Spanish tertiary hospital, before, during and after confinement during the COVID19 pandemic.

Material and methods
Retrospective, descriptive and cross-sectional study of patients with a histological diagnosis of lung cancer studied in a tertiary hospital from 01.01.2019 to 03.31.2022. The patients studied during period 1, defined as prior to confinement (01.01.2019-14.03.2020), period 2, from confinement until the end of 2020, and period 3, from the beginning of 2021 to the first quarter of 2022 have been analysed. The number of patients, their clinical characteristics and cancer staging, as well as the differences in symptom times until referral, duration of the diagnostic study until the decision of the tumour committee and time until the start of the first treatment have been analysed. SPSS 22 program has been used for the statistical analysis.

Results
584 patients have been studied, 228 in period 1, 84 in period 2 and 272 in period 3.

Table 2: differences between periods.

Conclusions
1- The initial months of the pandemic caused a decrease in the number of diagnosed lung cancers.
2- Despite this, we have not observed significant differences in the stage or in the situation of the patient at diagnosis in the different periods of time analysed
3- No significant differences been observed in the times until consultation, diagnosis or treatment.
