EGFRmutでTKI後のADC製剤の成績。
正直、かなりのlate line、3rd generation TKIで
この成績なのはすごい。
.@chris_dickhoff presents results from INCREASE trial (surgery after chemoRT+I/O for borderline resectable NSCLC): 63% pCR, 79% major pathologic response, only 15% radiographic response (may be related to nodal flare?). Insightful discussion from @PatelOncology. #WCLC23 pic.twitter.com/RLdfVHIEgO

IO＋CRTでボーダラインの肺がんのｐCRが63%とのこと
ただ、15%しか放射線学的には縮んでなかったとのこと
これを踏まえて

pCRs after RT for NSCLC #lungcancer are rich #radonc data...
The INCREASE trial:
chemoRT(50Gy)+ipi+nivo
surgery @ 6wks post-RT
pCR: 63%
SWOG 9416 kind of similar setup, minus immunotx
chemoRT 45 Gy, surgery 3-5 weeks
pCR: 36%https://t.co/qLJayrA0mO https://t.co/5PDFXx5uUR
こんな意見も。
ISABR
From @MDAndersonNews , @JoeChangMD presents the results of the ISABR study at #WCLC23

🚨 IO when added to #SABR in stage 1 NSCLC improves 4yr EFS 53% vs 77%
➡️ Phase 3 study awaited
➡️ Can radiomics identify those patients who will benefit the most? pic.twitter.com/oU0vOSqj4r

フォレストプロットや
副作用はnoteではあまり触れてなかったのでスライドを
間違いなくIII相が待たれます。
ラジオミクスの話は確かに、という感じ

So my personal take home from the EORTC consensus definition of resectability in stage III NSCLC - not much consensus around the contentious groups. Still will be driven by MDTs until we have trials #WCLC23 pic.twitter.com/zPYtFMxIaw

EORTCの`resectable`のコンセンサス
今後外科に流れるのは致し方なしか。
N2は「組織をつけろ」が海外の常識
.@peters_solange presents 6yr CM227 part 1 data. Impressive and maintained N/I OS for PDL1negs, esp DOR & 6yr PFS rate #WCLC23 pic.twitter.com/33D3xWOKNL

ケモ＋イピニボで日本ではイピニボ人気ないが、
やはり使いどころはあるレジメンと感じる。
とくにPD-L1発現低いのは使いたい…

Paradigm-shifting study by @ekslim et al: MARS-2 trial w/ @paugalde20 discussion. pleurectomy / decortication + chemo Vs chemo. Surgery had worse OS: HR 1.28, p=0.03. 2nd landmark surgery RCT from the UK team presented at #WCLC23 by @ekslim in past 3 years. pic.twitter.com/bqBjFX0PdH

.@ekslim presents MARS2. Undoubted reduced survival with surgery (EPD) n=355. 28% increased risk of death. No difference due to chemo impact. QOL worse for surgery. Time to dismiss the concept of resectability #WCLC23 @IASLC #mesothelioma pic.twitter.com/1Yf1eqOWxt

今までのところ一番みんな衝撃を受けているstudyのよう
MARS-2
要は中皮腫でケモvs.ケモ＋手術で
（超長期はまだ見ないといけないが）
ケモのほうが
・死亡リスク少ない
・副作用少ない
・QOL良い
・費用対効果も優れる
と呼吸器外科医の心を折りかねない結果…
