Pdf Summary

The study analyzed the incidence and resource burden of managing ground glass opacities (GGOs) detected on CT scans at a tertiary lung cancer service in the UK. GGOs are abnormal findings on CT scans that can range from precancerous lesions to invasive cancer. The study aimed to evaluate the trends and quantify the impact of increased CT scans and follow-up imaging on resources. Retrospective data from patients discussed at lung cancer multi-disciplinary team (MDT) meetings between two hospitals over a three-year period were analyzed.<br /><br />Between 2017 and 2019, a total of 3,731 patients were discussed at the lung MDT, with 11% of them having sub-solid nodules (SSNs) on CT. The number of patients with SSNs increased over the three-year period. Among the SSN cases, 259 patients had GGOs. The incidence of GGO discussions also increased annually. The median follow-up time for these patients was 8.7 months, during which they underwent a median of 3 scans with a median time interval between scans of 2.9 months.<br /><br />Out of the GGO subset, 25% received PET scans and biopsies were performed on 12% of patients, confirming cancer in 62.5% of the biopsy cases. A total of 7% of patients underwent surgical intervention for suspected neoplasms, with adenocarcinoma being the most common histology finding.<br /><br />The study highlighted the significant and increasing incidence of GGO discussions in the lung MDT. The patients received multiple scans over a relatively short follow-up period. The authors emphasized the need for more effective methods and pathways for managing GGOs, especially with the potential implementation of a lung cancer screening program. The study also pointed out the challenge of determining the clinical significance of GGOs and the importance of establishing selective follow-up pathways.<br /><br />In conclusion, the study revealed a growing burden of managing GGOs detected on CT scans in a lung cancer service in the UK. The increasing incidence of GGO discussions and the extensive follow-up imaging required indicate the need for improved methods for managing GGOs and determining their clinical significance.
