“ctDNA during perioperative ChT in resectable gastric/GEJ cancer

ctDNA detection rates
56% at baseline
37% After 1cycle ChT

25% after preoperative chemotherapy 15% after resection
Detection of ctDNA after 1 cycle of ChT -> RFSOS
Detection of ctDNA after surgery -> RFSOS

Correlations with pathologic responses?
ctDNA after adjuvant ChT?”

Circulating tumor DNA predicts recurrence and survival in patients with resectable gastric and gastroesophageal junction cancer
