Study of the Immunity of Patients With Lung Cancer and COVID-19 Infection (SOLID)

February 5, 2026 updated by: Fundación GECP

Study of Acquired Immunity in Patients With Lung Cancer and COVID-19 Infection

Observational, retrospective data collection and prospective IgG analysis, and multicenter study.

The main objective of the study is th description of the characteristics and evolution of patients with lung cancer who have acquired COVID-19 infection.

For the identification of patients who contract COVID-19 infection, the IgG+ blood test by ELISA method will be used.

Detailed Description

Non-post-authorization study, retrospective of data collection and prospective of IgG analysis, observational and multicenter.

The study will be extended to all the sites of the Spanish Lung Cancer Group, more than 170 centers and 500 professionals, and it is expected that around 1,500 IgG tests will be carried out.

The study has three phases:

The scope of phase I is the identification of acquired immunity (IgG) in patients with lung cancer, whether or not they have presented symptoms of having suffered from COVID19. In addition, the description of the characteristics and evolution of patients with lung cancer who have contracted COVID-19 infection will be carried out.

For the identification of patients who contract COVID-19 infection, the IgG+ test in blood will be used by ELISA method.

The scope of phase II is the confirmation of the presence of antibodies (IgG) in patients who tested positive in Phase I of the study a few weeks after the first diagnosis made through the SOLID study.

The scope of phase III is the confirmation of the presence of antibodies (IgG) in patients with lung cancer who have been vaccinated with any of the available and authorized vaccines for SARS-COV2 and 6 months after said administration.
