Abstract:
Objective To investigate the views of doctors on the incidence and treatment tactics of mild progression after epithelial growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) treatment in lung adenocarcinoma and provide suggestions to optimize the countermeasure strategies.
Methods Convenience sampling was used to conduct an online questionnaire survey for doctors specializing in oncology and respiratory diseases.
Results 584 valid questionnaires were collected, and all the doctors expressed concerns regarding mild tumor progression after EGFR-TKI treatment. The coping strategies included maintaining the original TKI treatment, adding other treatments to the original TKI, changing the regimen, and performing secondary tissue biopsy, among which, most doctors chose to add other treatments to the original TKI.
Conclusions Doctors have noticed the enlargement of target lesions in still stable disease (SD) and most frequently chose to add other treatments to the original TKI as a coping strategy. This finding can provide a reference for framing future guidelines for large sample prospective clinical studies that are needed to find the most effective synergistic treatment options.
