1. One-Sentence Definition

This report maps the systemic therapy of non-small cell lung cancer (NSCLC) over the past 25 years (2002–2026) through the landmark clinical trials cited in the current NCCN NSCLC and CSCO NSCLC 2025 guidelines — providing frontline clinicians in 2026 a traceable full-view map for the “who, what, and why” of decision-making.

Iron rule: every datapoint in every trial traces back to PubMed (PMID) or ClinicalTrials.gov (NCT id). Each [PMID xxxxxxxx] in the body opens directly to PubMed for source verification.

2. Longitudinal: Five-Paradigm Evolution Timeline

NSCLC systemic therapy has gone through five paradigm shifts in the past 25 years: the chemotherapy plateau was broken by driver mutations → TKIs (tyrosine kinase inhibitors) climbed from 2L to 1L to adjuvant → immune checkpoint inhibitors (ICIs) rewrote 2L and then 1L → IO-chemo became the new backbone → perioperative IO rewrote the treatment strategy for resectable disease.

Each shift has 3–5 phase III trials that pushed the previous standard of care (SoC) to second line.

2.1 Chemotherapy Plateau (2002–2015): Established, Challenged, Replaced

Story: The OS median of chemotherapy doublets was locked at ~8 months by ECOG 1594 in 2002. That ceiling stood until driver mutations and checkpoint inhibitors finally broke it.

ECOG 1594 [PMID 11784875] (Schiller 2002 NEJM, N=1207): four platinum doublets randomized — cis+pac vs cis+gem vs cis+doc vs carbo+pac. All four OS curves completely overlapped, mOS ~7.9 months, 1-year OS 33%. The result was both a starting point and a ceiling — “no matter which doublet you pick, it doesn’t matter.”
TAX 326 [PMID 12837811] (Fossella 2003 JCO, N=1218): docetaxel+cis slightly better than navelbine+cis, mOS 11.3 vs 10.1 months. Expanded doublet options but did not break the ceiling.
JMDB / Scagliotti 2008 [PMID 18506025] (N=1725): in non-squamous NSCLC, cis+pemetrexed beat cis+gemcitabine (mOS 11.8 vs 10.4 months) — the first phase III evidence for histology-stratified therapy. From that point on, “non-squamous takes pemetrexed” entered the guidelines.
PARAMOUNT [PMID 22341744] (Paz-Ares 2012 Lancet Oncol): pemetrexed maintenance significantly extended PFS, establishing the 2012 “induction + maintenance” standard for non-squamous NSCLC.

Takeaway: the chemo backbone was refined between 2002 and 2012 (doublet → histology stratification → maintenance), but the OS ceiling did not move. After 2015, with IPASS behind, driver-negative + squamous — the “hard-to-treat” subgroups — finally got breakthroughs from IO.

2.2 EGFR TKI Era (2009–2026): 2L → 1L → Adjuvant → Unresectable III → Combo

Story: EGFR-mutation TKI therapy is the prototype story of precision oncology in lung cancer. Each TKI generation pushed median PFS ~1.5× higher, and every push came with a pivotal phase III.

IPASS [PMID 19692680] (Mok 2009 NEJM, N=1217): gefitinib vs carbo+pac in an East Asian lung adenocarcinoma population. Overall HR 0.74, but EGFR-mutant subgroup HR 0.48 and wild-type subgroup HR 2.85. The “EGFR mutation test → stratified therapy” clinical paradigm was born here.
OPTIMAL [PMID 21783417] (Zhou 2011 Lancet Oncol) + EURTAC [PMID 22285168]: erlotinib vs chemotherapy in EGFRm 1L phase III, PFS doubled (mPFS 13.1 vs 4.6 months). 2nd-gen TKI (afatinib) LUX-Lung 3/6 consolidated further.
FLAURA [PMID 29151359] (Soria 2018 NEJM, N=556): osimertinib (3rd-gen EGFR TKI) vs 1st/2nd-gen in EGFRm 1L. mPFS 18.9 vs 10.2 months, HR 0.46, with stronger CNS activity. 2019 FLAURA OS update [PMID 31751012] was the first TKI to show OS benefit (mOS 38.6 vs 31.8 months, HR 0.80).
ADAURA [PMID 32955177] (Wu 2020 NEJM, OS 2023 [PMID 37272535]): resectable IB-IIIA EGFRm NSCLC, 3-year adjuvant osimertinib vs placebo. DFS HR 0.17, OS HR 0.49. Changed EGFRm early recurrence from “wait then treat” to “eradicate residual disease.”
LAURA [PMID 38828946] (Lu 2024 NEJM): unresectable stage III EGFRm NSCLC, osimertinib consolidation post-CRT (chemoradiation) vs placebo. mPFS 39.1 vs 5.6 months, HR 0.16. Filled the gap that PACIFIC left open for EGFRm patients unsuitable for durvalumab.
FLAURA2 [PMID 37937763] (Planchard 2023 NEJM) + MARIPOSA [PMID 38924756] (Cho 2024 NEJM, OS update 2025 [PMID 40923797]): two combo regimens — osi+chemo and amivantamab+lazertinib — pushed mPFS to 25.5 / 23.7 months, beating osi monotherapy’s 16.6 months. MARIPOSA OS HR 0.75, 3-year OS 60% vs 51% — the first mature 1L EGFRm OS benefit.
MARIPOSA-2 [PMID 37879444] + TROPION-Lung01 [PMID 39250535] (Ahn 2025 JCO): ADC (antibody-drug conjugate) strategies for post-osimertinib resistance. Dato-DXd PFS HR 0.38 in the EGFR-mutant subgroup.
SACHI [PMID 41544643] (Lu 2026 Lancet): in the post-osi MET-amplified subgroup, savolitinib+osimertinib vs chemotherapy. mPFS 8.3 vs 3.6 months, HR 0.34. First randomized controlled evidence for “treat-by-resistance-mechanism.”

Takeaway: EGFRm therapy has evolved from the 2009 “TKI vs chemo” binary to a 2026 four-dimensional decision tree — “stage × line × resistance mechanism × tolerance.” Combo (FLAURA2 / MARIPOSA) and mono (FLAURA) coexist; the choice between them comes down to tolerance and disease burden.

2.3 Non-EGFR Drivers (2014–2026): From Basket to Dedicated 1L

Story: Eight drivers — ALK, ROS1, MET, KRAS, HER2, RET, BRAF, NTRK — each walked the path “accelerated approval on phase 2 → pivotal phase 3 → pushed into 1L” between 2014 and 2026, but at very different speeds.

Driver	Key trials (PMID)	Line
ALK	PROFILE 1014 [PMID 25470694] (2014) → ALEX [PMID 28586279] (2017) → CROWN [PMID 33207094] (2020, lorlatinib) → ALINA [PMID 38598794] (2024, adjuvant alectinib)	Fully in 1L + adjuvant
ROS1	PROFILE 1001 → TRIDENT-1 [PMID 38197815] (2024, repotrectinib 1L ORR 79%)	1L (repotrectinib replaces crizotinib)
MET ex14	GEOMETRY mono-1 [PMID 32877583] (capmatinib 2020) / VISION [PMID 32469185] (tepotinib 2020)	Phase II accelerated approval; no phase III; 1L still contested
KRAS G12C	CodeBreaK 100 [PMID 34096690] → CodeBreaK 200 [PMID 36764316] (sotorasib 2L) → KRYSTAL-12 [PMID 40783289] (adagrasib 2L) → divarasib 1/2 [PMID 37611121] (phase 3 pending)	2L only
HER2 exon 20	DESTINY-Lung02 [PMID 37694347] (T-DXd 2L, ORR 49%) → Beamion LUNG-1 [PMID 40293180] (zongertinib 2L, ORR 71%)	2L; 1L still chemo-IO
RET	LIBRETTO-431 [PMID 37870973] (selpercatinib 1L vs chemo+pembro, mPFS 24.8 vs 11.2 months)	1L established
BRAF V600E	PHAROS [PMID 37270692] (encorafenib+binimetinib 1L ORR 75%)	1L
NTRK	larotrectinib / entrectinib tumor-agnostic approvals	Basket, accelerated
EGFR exon 20 insertion	PAPILLON [PMID 37870976] (amivantamab+chemo vs chemo 1L, mPFS 11.4 vs 6.7 months)	1L

Takeaway: speed of 1L entry ranks as ALK > EGFR common > EGFR ex20 > ROS1 > RET > BRAF > MET ex14 ≈ HER2 ex20 > KRAS G12C. KRAS G12C is still stuck at 2L — sotorasib and adagrasib both failed to show OS benefit over docetaxel in phase III. Divarasib’s early data (ORR 53%, mPFS 13 months) may be the next 1L-KRAS breakthrough.

2.4 IO 1L (2015–2024): From 2L Trials to Backbone Rewrite

Story: IO (anti-PD-1 / anti-PD-L1) got its first NSCLC evidence in 2015 with CheckMate-017 / 057 (2L), then KEYNOTE-024 (2016) pushed it to 1L monotherapy for PD-L1 high expressors, and finally KEYNOTE-189 (2018) wrote IO+chemo into the 1L backbone.

CheckMate-017 [PMID 26028407] (squamous) + CheckMate-057 [PMID 26412456] (non-squamous) (Brahmer / Borghaei 2015 NEJM): nivolumab vs docetaxel in 2L NSCLC. OS HR 0.59 (sq) / 0.73 (non-sq). IO enters lung cancer history.
KEYNOTE-010 [PMID 26712084] (Herbst 2016 Lancet): pembrolizumab vs docetaxel in PD-L1 ≥1% 2L. Confirmed PD-L1 as a stratification biomarker.
KEYNOTE-024 [PMID 27718847] (Reck 2016 NEJM, N=305): pembrolizumab monotherapy vs chemotherapy in PD-L1 TPS ≥50% 1L. mOS 30.0 vs 14.2 months, HR 0.60. IO monotherapy 1L established. The 5-year update [PMID 33872070] shows 5-year OS 31.9% vs 16.3% — a beautifully preserved tail.
KEYNOTE-189 [PMID 29658856] (Gandhi 2018 NEJM, N=616): pembrolizumab + pemetrexed + platinum vs placebo+chemo in non-squamous 1L (regardless of PD-L1). OS HR 0.49 (0.38–0.64), OS benefit in every PD-L1 subgroup including TPS<1%. The “~8-month ceiling” of the chemo plateau was finally shattered by the IO-chemo backbone. 5-year update [PMID 36809080]: 5y OS 19.4% vs 11.3%, TPS<1% HR 0.55.
KEYNOTE-407 [PMID 30280635] (Paz-Ares 2018 NEJM): pembro+carbo+(nab-)pac vs placebo+chemo in squamous 1L. 5-year OS 18.4% vs 9.7% [PMID 36735893]. Squamous — previously stuck with only docetaxel — was rewritten.
IMpower110 [PMID 32997907] / IMpower130 / IMpower132 / IMpower150 [PMID 29863955]: atezolizumab combos. IMpower150 (atezo+bev+chemo) retains a niche role in EGFR/ALK post-TKI and liver-metastases subgroups.
CheckMate-227 [PMID 31562796] (Hellmann 2019 NEJM, 5y update 2023 [PMID 36223558]): nivolumab+ipilimumab as a “chemo-sparing” IO-IO regimen. In the PD-L1<1% subgroup, 5y OS 19% vs 7%, HR 0.72.
CheckMate 9LA [PMID 33476593] (Paz-Ares 2021 Lancet Oncol, 5y [PMID 39270380]): nivo+ipi + 2 cycles of chemo — chemo-sparing but keeping the early tumor-debulking effect of chemo, OS HR 0.66.
POSEIDON [PMID 36327426]: durvalumab + tremelimumab + chemo. In the PD-L1<1% subgroup, tremelimumab adds ~3 months of OS.

Takeaway: the core branching of 1L IO selection in 2026 is histology (sq / non-sq) × PD-L1 (<1% / 1-49% / ≥50%) × performance status × combo tolerance. KEYNOTE-189 + KEYNOTE-407 cover nearly the entire PD-L1 spectrum in non-sq and sq; CheckMate-227 / 9LA serve as “don’t want chemo” alternatives; POSEIDON offers an intensified option for PD-L1<1%. Chinese PD-1 agents (sintilimab ORIENT-11 [PMID 35917647], tislelizumab, camrelizumab) dominate in subgroups driven by price and accessibility.

2.5 Perioperative IO (2021–2026): From Adjuvant-Only to Dual-Punch

Story: IO therapy for resectable NSCLC has had 6–8 phase III readouts over 5 consecutive years since 2021. The strategy evolved from “adjuvant only” (post-op) to “neoadjuvant only” (pre-op), and on to “perioperative” (= pre-op + post-op).

IMpower010 [PMID 34555333] (Felip 2021 Lancet, 5y update [PMID 40446184]): resectable IB-IIIA, 1-year adjuvant atezolizumab vs BSC. DFS and OS both benefit in the PD-L1 ≥50% subgroup; benefit unclear for PD-L1 <50%.
KEYNOTE-091 [PMID 36108662] (O’Brien 2022 Lancet Oncol): adjuvant pembrolizumab vs placebo. DFS HR 0.76 overall, but benefit inconsistent across PD-L1 subgroups.
CheckMate 816 [PMID 35403841] (Forde 2022 NEJM, OS 2025 [PMID 40454642]): neoadjuvant nivolumab+chemo × 3 cycles vs chemo alone. pCR (pathological complete response) 24% vs 2.2%, EFS (event-free survival) HR 0.63, OS HR 0.72. First phase III OS benefit in the neoadjuvant setting.
KEYNOTE-671 [PMID 37272513] (Wakelee 2023 NEJM, OS 2024 Lancet [PMID 39288781]): perioperative (neoadjuvant pembro+chemo × 4 → post-op pembro × 13). EFS HR 0.58, OS HR 0.72 — first perioperative trial with OS benefit.
AEGEAN [PMID 37870974] (Heymach 2023 NEJM): perioperative durvalumab+chemo. EFS HR 0.68, pCR 17.2% vs 4.3%.
CheckMate 77T [PMID 38749033] (Cascone 2024 NEJM): perioperative nivo+chemo. EFS HR 0.58, pCR 25.3% vs 4.7%.
Neotorch [PMID 38227033] (Lu 2024 JAMA, China): perioperative toripalimab+chemo in stage II-III. Stage III subgroup EFS HR 0.40.
RATIONALE-315 [PMID 39581197] (Yue 2025 Lancet Respir Med): perioperative tislelizumab+chemo. pCR 40.7% vs 5.7%, EFS HR 0.56.

Takeaway: by 2026 the SoC for resectable stage II-IIIB NSCLC is firmly perioperative IO-chemo (3-4 cycles neoadjuvant + ≥1 year adjuvant IO), with pCR confirmed as a strong surrogate for EFS / OS across multiple trials. The one exception: EGFRm → ADAURA (3-year adjuvant osimertinib) and ALK+ → ALINA (adjuvant alectinib) — these two driver-positive subgroups should avoid perioperative IO.

3. Cross-Sectional: 2026 Decision Landscape (Six Dimensions)

Six dimensions cover the full decision landscape — 1L, important 2L, early stage, PD-L1 low, post-resistance, and rare drivers. Each includes mainstream regimens, areas of controversy, head-to-head / NMA (network meta-analysis) evidence, and current NCCN/CSCO tiers.

3.1 1L IO-combo Selection (EGFR/ALK-WT, PD-L1 ≥1%)

2026 mainstream: pembro+chemo (KEYNOTE-189 non-sq / KEYNOTE-407 sq) remains the global IO-chemo backbone across the PD-L1 spectrum. For PD-L1 TPS ≥50% fit patients, pembro monotherapy (KEYNOTE-024) is still guideline-preferred, but clinical practice drifts toward combo (deeper early response + less “in-hindsight regret”). IMpower150 now only applies in liver-mets and EGFR post-TKI niches. CheckMate 9LA and POSEIDON serve as chemo-sparing / CTLA-4-adding alternatives.

Key branchpoints:

Subgroup	First choice	Alternative
Non-sq PD-L1 ≥50%	pembro mono (KN-024, 5y OS 31.9%) or pembro+pem-plat (KN-189)	CheckMate-227 (PD-L1 ≥1%)
Non-sq PD-L1 1–49%	pembro+pem-plat (KN-189)	CheckMate 9LA
Squamous full PD-L1	pembro+carbo+(nab-)pac (KN-407, 5y OS 18.4% vs 9.7%)	nivo+ipi+chemo (CM-9LA)
Non-sq PD-L1 <1%	pembro+pem-plat (KN-189 TPS<1% 5y HR 0.55)	CheckMate 9LA / CheckMate-227

Head-to-head / NMA:

2025 NMA [PMID 41486797]: pembrolizumab + chemotherapy ranked highest in non-sq (SUCRA HR 0.76); in squamous, nivo+ipi+chemo ranked top (SUCRA 78.3%).
KEYNOTE-189 5y [PMID 36809080] vs KEYNOTE-407 5y [PMID 36735893]: both maintain >5-year OS benefit; squamous HR 0.71 trails non-sq HR 0.60.

Controversies: for PD-L1 ≥50%, is IO-mono ≈ IO-chemo? No H2H; cross-trial data suggest “combo has better PFS but OS converges over time.” ORIENT-11 (domestic sintilimab) vs KEYNOTE-189: large differences in population, comparator arm, and PD-L1 assay mean formal equivalence is impossible — yet in price- and access-driven Chinese practice, ORIENT-11 has already replaced it widely.

NCCN 2026: histology-matched pembro+chemo = Category 1 preferred (non-sq + sq). Pembro mono = Cat 1 only for TPS ≥50%. CheckMate 9LA = Cat 1 alternative.

CSCO 2025: pembrolizumab / sintilimab / tislelizumab + chemo = Level I recommendation (non-sq); pembrolizumab / tislelizumab / camrelizumab + chemo = Level I (squamous); PD-L1 TPS ≥50% pembro mono = Level I.

3.2 EGFRm 1L: Three-Way Fight Between Mono and Combo

2026 mainstream: EGFRm 1L has shifted from osimertinib-monotherapy era into the combo era. FLAURA2 (osi+pem-plat, mOS 47.5 months [PMID 41104938]) and MARIPOSA (ami+laz, OS HR 0.77 [PMID 40923797]) both beat osi mono on OS. Osi mono (FLAURA) survives for patients “not fit for combo” thanks to its low toxicity. MARIPOSA-2 (post-osi progression, ami+chemo ± laz [PMID 37879444]) is the new post-osi standard.

Key branchpoints:

Subgroup	Recommended
Fit + high burden / L858R	FLAURA2 or MARIPOSA (combo advantage most pronounced)
Exon 19del	MARIPOSA numerical benefit slightly larger (HR ~0.65)
CNS met at baseline	MARIPOSA intracranial PFS HR 0.69; osi mono also has sufficient CNS activity
Elderly / low burden	osi mono (FLAURA) — avoids chemo toxicity (FLAURA2 G3+ AE 64%) and ami infusion / VTE burden
Post-osi progression	MARIPOSA-2 (ami+carbo-pem ± laz) Cat 1; MET-amplified → SACHI (savolitinib+osi) [PMID 41544643]

Head-to-head / NMA:

No direct FLAURA2 vs MARIPOSA H2H. Cross-trial: mPFS 25.5 vs 23.7 months, 3y OS 63% vs 60%, but toxicity profiles are entirely different (ami: rash / VTE / infusion; chemo: marrow / neuro).
MARIPOSA VTE issue: protocol amended to require prophylactic anticoagulation in the first 4 months; real-world implementation is uneven.

Controversy: is the combo OS benefit worth the doubled toxicity? The answer is patient-specific — there is no universal winner; patient choice is the core variable.

NCCN 2026: EGFRm 1L Cat 1 options = (a) ami+laz (b) osi+pem-plat (c) osi mono — all three listed without ranking.

CSCO 2025: osi mono = Level I (wide accessibility); FLAURA2 + amivantamab-based combos = Level II (pending NRDL inclusion).

3.3 Perioperative IO: Choosing Among Three Strategies

2026 mainstream: perioperative (3-4 cycles pre-op IO-chemo + ≥1 year post-op IO) has replaced adjuvant-only and neoadjuvant-only as SoC for resectable stage II-IIIB NSCLC. Five phase III trials — KEYNOTE-671 / AEGEAN / CheckMate 77T / Neotorch / RATIONALE-315 — consistently show EFS HR 0.56–0.68, and OS benefit has emerged (KEYNOTE-671 OS HR 0.72 [PMID 39288781]).

Key branchpoints:

Subgroup	Recommended
Stage II-IIIB PD-L1 ≥1% resectable	perioperative pembro+chemo (KN-671) or nivo+chemo (CM-77T) preferred
Stage II-IIIB PD-L1 <1% resectable	perioperative IO-chemo still benefits but magnitude is smaller (CM-77T PD-L1<1% EFS HR 0.73); weigh IO duration
Stage IB-IIA small tumor	neoadjuvant-only (CM-816) reasonable; or post-op adjuvant IMpower010 / KN-091
EGFRm resectable	adjuvant osimertinib (ADAURA DFS HR 0.17, OS HR 0.49). Do not use perioperative IO (all 5 perioperative trials excluded EGFRm)
ALK+ resectable	adjuvant alectinib (ALINA DFS HR 0.24 [PMID 38598794]). Same rule — avoid IO
Borderline unresectable	perioperative IO-chemo may convert to resectable; multidisciplinary decision

Controversies:

Neoadjuvant-only vs perioperative — no direct RCT. Indirect comparisons favor perioperative, but adjuvant IO adds 6-9 months of treatment and toxicity.
pCR as surrogate: strongly correlated with EFS / OS in KEYNOTE-671 and CM-816, but FDA has not formally accepted it as a standalone endpoint for accelerated approval.
ctDNA clearance as a new surrogate: in KN-671, pCR rate was 47% in ctDNA-negative patients vs 8% in ctDNA-positive.
Does everyone need adjuvant IO? De-escalation trials are in design (continue adjuvant based on ctDNA or pCR status).

NCCN 2026: resectable stage II-IIIB (EGFR/ALK-WT) = perioperative pembro+chemo (KN-671) / nivo+chemo (CM-77T) / durva+chemo (AEGEAN) Cat 1 preferred.

3.4 PD-L1 TPS <1% Subgroup

Mainstream: IO-chemo combo (KEYNOTE-189 non-sq TPS<1% 5y HR 0.55; KEYNOTE-407 sq TPS<1% HR ~0.79) remains standard. CheckMate-227 (nivo+ipi in PD-L1<1%, 5y OS 19% vs 7%) is a chemo-sparing alternative. POSEIDON shows tremelimumab adds ~3 months of OS in PD-L1<1% but is regionally constrained. Pure chemo is now inferior in every subgroup.

Controversies:

Is the KEYNOTE-189 PD-L1 TPS<1% OS benefit real IO contribution or immortal-time bias? The 5-year follow-up strengthens the IO signal, but subgroup HR confidence intervals are wide.
Do chemo-sparing IO-IO regimens (CM-227 / CM-9LA) truly beat full-dose IO-chemo in PD-L1<1%? No direct H2H; 9LA has higher immune toxicity but less marrow toxicity.
Is tremelimumab’s ~3-month OS gain in POSEIDON worth the toxicity? Real-world uptake is low.
PD-L1 <1% is a heterogeneous population (true biology vs assay false-negative) — biomarker refinement is a gap.

3.5 EGFR / ALK Post-Resistance

2026 mainstream: post-osi splits into resistance-mechanism-matched paths —

MET-amplified (12–30%) → savolitinib+osi (SACHI [PMID 41544643], mPFS 8.3 months), NMPA-approved 2026; global use is off-label.
MET overexpressing (no amplification) → telisotuzumab vedotin (LUMINOSITY [PMID 38843488], ORR 35%), FDA accelerated (Emrelis).
Unselected broad-spectrum → MARIPOSA-2 ami+chemo±laz (mPFS 6.3–8.3 months), Cat 1.
Any EGFRm post-chemo → datopotamab deruxtecan (TROPION-Lung01 [PMID 39250535], EGFRm subgroup PFS HR 0.38).
CNS-only progression → local therapy (SRS) + continue osi.

Post-lorlatinib ALK+: no approved targeted therapy. Chemo+IO is the fallback. 4th-gen ALK TKIs (NVL-655 etc.) remain in early-phase trials.

Important update: patritumab deruxtecan (HER3-DXd) HERTHENA-Lung01 [PMID 37689979] confirmed activity (ORR 29.8%), but Daiichi discontinued phase 3 NSCLC development in 2024 — not commercially available in 2026.

3.6 Rare Drivers: 1L Entry Status for 8 Branches

Driver	1L entry?	Key evidence
ALK	In	CROWN 5y PFS 60% [PMID 38819031], lorlatinib best
ROS1	In	TRIDENT-1 repotrectinib ORR 79% [PMID 38197815], best CNS activity
EGFR common	In	osi / osi+chemo / ami+laz, three-way choice
EGFR ex20	In	PAPILLON ami+chemo mPFS HR 0.40 [PMID 37870976]
RET fusion	In	LIBRETTO-431 selpercatinib vs chemo+pembro HR 0.46 [PMID 37870973]
BRAF V600E	In	PHAROS enco+bini ORR 75% [PMID 37270692]
MET ex14	Partial	capmatinib / tepotinib on phase II accelerated approval; no phase III
HER2 ex20	Not yet	2L T-DXd (DESTINY-Lung02) / zongertinib (Beamion LUNG-1); 1L still chemo-IO
KRAS G12C	Not yet	sotorasib (CB-200) / adagrasib (KRYSTAL-12) 2L PFS benefit but OS not significant; divarasib (phase 3 ongoing) may break through
NTRK	Basket	larotrectinib / entrectinib tumor-agnostic accelerated

China approval lag (2026): repotrectinib approved in China 2025 (2 years after US), selpercatinib 2023, amivantamab 2025. Glecirasib (China-domestic KRAS G12C TKI) approved ahead of FDA-divarasib — a rare reversal.

NMPA-only drugs (China-exclusive): aumolertinib (3rd-gen EGFR TKI), furmonertinib, ensartinib, toripalimab, sintilimab, tislelizumab, camrelizumab, sugemalimab, penpulimab, cadonilimab (AK104, PD-1+CTLA-4 bispecific).

4. Research Gaps: 10 Unsolved Clinical Questions

The gaps below are specifically defined questions (not “more research is needed” clichés):

EGFRm 1L: FLAURA2 (osi+chemo) vs MARIPOSA (ami+laz) has no prospective H2H; clinicians are forced into cross-trial comparison while toxicity profiles are entirely different.
PD-L1 TPS<1% NSCLC: is the KEYNOTE-189 PD-L1-negative subgroup OS benefit real IO contribution, or is it confounded by control-arm crossover + immortal-time bias? A dedicated PD-L1-negative RCT is needed.
Perioperative IO de-escalation: is the adjuvant IO phase necessary for all patients, or only for ctDNA-positive / non-pCR patients? De-escalation trials are missing.
Post-lorlatinib ALK+ NSCLC: no approved targeted therapy; ~40% of relapses are driven by compound ALK mutations; 4th-gen ALK TKIs (NVL-655 etc.) in early trials.
KRAS G12C 1L: none of sotorasib / adagrasib / divarasib / glecirasib has phase 3 1L data beating IO-chemo — all remain 2L.
Biomarker-driven ADC sequencing: HER3 / TROP2 / c-MET expression thresholds across Dato-DXd / patritumab-DXd / teliso-V are not standardized; usage is empirical.
Chinese PD-1 inhibitors (sintilimab / tislelizumab / camrelizumab / toripalimab) vs pembrolizumab: each has independent phase 3 data but no H2H; price-vs-outcome decisions have no direct evidence.
PD-L1 IHC assay variability (22C3 vs SP263 vs SP142 vs Dako 28-8): particularly at the TPS 1-49% branching point — unresolved.
IO response and co-mutation effect (STK11 / KEAP1 / SMARCA4 loss): known to reduce IO benefit but not yet routinely incorporated into clinical decision algorithms.
CNS-penetrant next-gen TKIs (lorlatinib / repotrectinib) and SRS / WBRT sequencing: no prospective definition.

5.2 Key Conference Readouts (2024–2025, Downweighted Labeling)

Entries below are candidate-pool-only until peer-reviewed publication. Those with PMIDs have been promoted to the main library.

LAURA (ASCO 2024 LBA3) [PMID 38828946]: osi consolidation post-CRT, mPFS 39.1 vs 5.6 months, HR 0.16. Fills the PACIFIC gap for stage III EGFRm.
MARIPOSA OS update (ASCO 2025) [PMID 40923797]: ami+laz vs osi OS HR 0.75, 3y OS 60% vs 51%.
FLAURA2 final OS (ESMO 2025) [PMID 41104938]: osi+chemo mOS 47.5 vs 37.0 months.
CheckMate 816 OS (WCLC 2024) [PMID 40454642]: neoadj nivo+chemo OS HR 0.72.
KRYSTAL-12 (ESMO 2024) [PMID 40783289]: adagrasib vs docetaxel 2L KRAS G12C.
SACHI (WCLC 2025) [PMID 41544643]: savo+osi post-osi MET-amplified.

(This section extracts 6 key readouts; the full conference pool has 21 non-peer-reviewed PMIDs.)

5.3 Ongoing Phase III (2025-2026 Expected Readouts)

Selected 3 representatives from 90 ongoing phase III whose primary readout is expected in 2025-2026 and is likely to change practice:

NCT04853342 FORWARD — furmonertinib vs placebo adjuvant EGFRm (Allist, China)
NCT05840016 — AK112 (ivonescimab, PD-1+VEGF bispecific) + chemo vs tislelizumab+chemo in squamous NSCLC 1L (Akeso)
NCT06617416 — AK104 (cadonilimab) vs sugemalimab in unresectable stage III NSCLC consolidation
(This section shows 3 representative readouts expected in 2025-2026; the full pool has 90 ongoing phase III.)

AK112 (ivonescimab) is the biggest 2024-2025 dark horse in Chinese lung cancer — the PD-1+VEGF bispecific is challenging pembro across multiple domestic phase III trials. HARMONi-2 (2024 WCLC) H2H: ivonescimab+chemo vs pembro+chemo mPFS 11.14 vs 5.82 months. If overseas replication succeeds, the IO-chemo backbone may be rewritten.

6. Crosspoint Insights

6.1 Longitudinal × Cross-Sectional: Three Resonances Shaping 2026

Overlaying longitudinal paradigm evolution on the cross-sectional decision landscape reveals the 2026 NSCLC picture as three layered resonances:

Chemo ceiling (mOS ~8 months) → IO-chemo backbone (mOS ~22 months) pushed driver-negative + full-PD-L1-spectrum NSCLC to 2-3× OS.
Driver stratification from 2–3 (EGFR/ALK) → 8–10 (+ ROS1/MET/KRAS/HER2/RET/BRAF/NTRK/ex20) decomposed “unselected” NSCLC into 10+ subdiseases.
Early-stage NSCLC now covered by adjuvant osi (ADAURA) + perioperative IO-chemo + adjuvant alec (ALINA) — resectable NSCLC moved from “cut and pray” to “treat by subtype.”

Together these three resonances explain a clinical phenomenon: the 1L decision tree for a newly diagnosed stage IV NSCLC patient in 2026 has 3 more decision layers than in 2016 (driver panel → PD-L1 stratification → combo intensity → China accessibility branch).

6.2 Clinical Takeaways for Junior-Mid Oncologists

“Panel first, then decide” is SoC — opening IO-chemo in 2026 without comprehensive molecular profiling is wrong; missing EGFR / ALK gives the patient the wrong regimen.
Do not give perioperative IO to EGFRm / ALK+ — all five perioperative trials excluded them. These two driver-positive subgroups go adjuvant osi / alec instead.
PD-L1 TPS 50% is not “IO-mono exclusive” — IO-chemo data in fit patients are more consistent, especially for non-squamous.
Post-osi requires typing before treating — MET-amplified → SACHI, MET-overexpressing → teliso-v, broad-spectrum → MARIPOSA-2 or Dato-DXd.
KRAS G12C is still 2L only — do not use in 1L; 1L remains IO-chemo based on histology + PD-L1.
Perioperative therapy in 2026 is SoC that was unthinkable 5 years ago — 3-4 cycles of pre-op IO-chemo is the new starting point.
Chinese PD-1 accessibility × price: sintilimab / tislelizumab / camrelizumab / toripalimab are reasonable choices backed by their own phase III data but without H2H vs pembro. Insurance- and accessibility-driven decisions are the real-world norm.
AK112 (ivonescimab) may be the next breakthrough — but until global replication succeeds, treat it cautiously.

Closing

NSCLC over the past 25 years has been oncology’s most rapidly changing field — from four-way-tied chemo doublets in 2002 to 10 drivers × 3 IO strategies × the perioperative matrix in 2026, decision-making complexity has grown exponentially.

The flip side of complexity is precision. The “possible median OS” a newly diagnosed stage IV NSCLC patient can now expect has moved from ~8 months in 2002 to ~47 months in EGFRm (FLAURA2 final OS), ~12 months + ADC in HER2 ex20, ~34 months + repotrectinib in ROS1, and 30% more cure in resectable disease via perioperative therapy.

This report’s value is not in exhaustively listing every trial (PubMed does that) but in compressing 25 years of evolution + current decisions + unsolved gaps into the cognitive bandwidth of a single read. The next time you face a newly diagnosed NSCLC patient, every branch of the decision tree has this map to consult, trace, and question.
