18F-FDG PET for the lymph node staging of non-small cell lung cancer in a tuberculosis-endemic country: is dual time point imaging worth the effort?
Our study demonstrates that PET is more accurate than CECT in LN staging NSCLC patients in Taiwan where TB is still prevalent. Semi-quantitative SUV method or DTPI with RI does not result in better diagnostic accuracy than visual analysis of PET images.
Continued EGFR-TKIs beyond PD may be a good option for elderly patients with non-dramatic progression. The characteristic of progression after first-line EGFR-TKIs treatment should be taken into account to determine which part of patients is suitable for continued EGFR-TKIs treatment, especially for the speed of progression.
