Molecular testing splits the road: without a driver mutation, chemo-immunotherapy comes before surgery and immunotherapy after; with an EGFR or ALK alteration, surgery is followed by a targeted tablet for two to three years.
Typical sequence for stage II-IIIA (resectable) disease; durations are protocol values (cycle counts and lengths, fraction schedules, guideline follow-up intervals), not averages of real patients. Your team's plan will differ in detail.
CT and PET-CT, brain MRI, biopsy with PD-L1 and a molecular panel (EGFR, ALK, ROS1, KRAS and others), mediastinal staging, lung function tests.
SourceThree 3-week cycles before surgery (CheckMate 816); the KEYNOTE-671 alternative gives four cycles with pembrolizumab.
SourceLobectomy with lymph node dissection 4-6 weeks after the last cycle; often minimally invasive or robotic.
SourceNo driver: adjuvant pembrolizumab for 13 cycles (39 weeks, KEYNOTE-671). EGFR-mutant: platinum chemotherapy (12 weeks) then osimertinib for 3 years (ADAURA). ALK-positive: alectinib for 2 years (ALINA).
SourceCT every 6 months for 2-3 years, then a low-dose CT yearly; smoking cessation support.
