Design outcomes
Primary
| Measure | Time frame |
|---|---|
| ?Re-biopsy ratio among the patients who had disease progression during EGFR-TKI treatment : All, by kind of sample ?The kind of sample for re-biopsy and the reason why its sample is selected. ?The mutation assay pattern to decide which treatment for next line: sample / assay method. ?The reason why re-biopsy is not performed | — |
Secondary
| Measure | Time frame |
|---|---|
| ?Timing to conduct re-biopsy and its status; the lesion at biopsy, biopsy method (e.g. core needle, FNA, excisional biopsy) and success rate of re-biopsy by samples. ?Occurrence of complications at re-biopsy, type of complications and its outcome. ?Kind of treatment and its duration till PD ?A site of recurrence after EGFR-TKI therapy ?Subsequent treatment pattern after re-biopsy (e.g., chemotherapy/targeted therapy used, palliative care, starting time of the next treatment line) by availability of re-biopsy and T790M testing, and/or by T790M testing outcome ?T790M prevalence among previous EGFR-TKI treatments and EGFR mutation sub-type at diagnosis ?In case other treatment is conducted after judgement of PD prior to re-biopsy [beyond PD, radiation therapy, et al], the detailed information of the treatment (method, timing, period) | — |
