Clinical significance of mutations (ESCAT)

Tumor-board context — the engine does not use these tiers to rank tracks

Biomarker	Variant	ESCAT	Evidence	Clinical significance	Drugs	Sources
BIO-PDL1-CPS	(gene-level)	IA	SRC-NCCN-ESOPHAGEAL-2025 SRC-ESMO-ESOPHAGEAL-2024 Evidence cited from clinical guidelines; per-source evidence levels not yet structured. See Phase-2-of-CIViC-pivot for re-cite roadmap.	PD-L1 CPS used as eligibility threshold for ICI in metastatic esophageal cancer. Esophageal SCC: CPS ≥10 — pembrolizumab + cisplatin + fluoropyrimidine 1L (KEYNOTE-590), and pembrolizumab monotherapy 2L (KEYNOTE-181 CPS≥10 subgroup). Esophageal adeno and GEJ: same CPS criteria as gastric adeno (NCCN 2025 treats GEJ adeno with gastric algorithm). Testing by IHC 22C3 pharmDx mandatory. Threshold-gated indication selection is performed by the algorithm layer (IND-ESOPH-METASTATIC-2L-PEMBRO-CPS10); this BMA entry surfaces ESCAT tier context only.	pembrolizumab + cisplatin + fluoropyrimidine (CPS≥10 SCC 1L per SRC-NCCN-ESOPHAGEAL-2025) pembrolizumab monotherapy (CPS≥10 SCC/adeno 2L per SRC-NCCN-ESOPHAGEAL-2025)	SRC-NCCN-ESOPHAGEAL-2025 SRC-ESMO-ESOPHAGEAL-2024

ID	Name	Priority	Category	Where to order	Needed for

Red flags — PRO / CONTRA aggressive

PRO-AGGRESSIVE

Triggers that push toward the aggressive track

Severe dysphagia with weight loss / aspiration risk in esophageal cancer: inability to swallow saliva, recurrent aspiration pneumonia, >10% weight loss in 3 months, OR malignant tracheoesophageal fistula. Mandates urgent palliative intervention (stenting OR dilation OR diversion) BEFORE any definitive systemic / RT therapy. RF-ESOPH-SEVERE-DYSPHAGIA-ASPIRATION

CONTRA-AGGRESSIVE

Hard contraindications to escalation

What NOT to do

Explicit prohibitive rules, each grounded in a regimen / supportive care / contraindication entity

Standard plan (IND-ESOPH-DEFINITIVE-CRT-SCC)

Do NOT escalate RT dose beyond 50.4 Gy — INT-0123 / RTOG 94-05 showed no OS benefit and increased toxicity at 64.8 Gy
Do NOT proceed with definitive CRT without addressing severe dysphagia / aspiration risk first (NG/PEG planning if needed)
Do NOT omit nutritional + esophagitis supportive care — CRT esophagitis peaks weeks 3-5 and limits hydration / oral intake
Do NOT switch to surgery-then-adjuvant pattern in a T4b unresectable patient — definitive CRT is the standard, not a bridge

MDT brief

Data quality

Usable with caveats. No critical default-track gap was found, but the MDT should review the listed caveats before final sign-off.
