CIRCULATING TUMOR DNA BASED DECISION FOR ADJUVANT TREATMENT IN COLON CANCER STAGE II

Обзор

The objective of CIRCULATE trial is to improve care of patients after colon tumor surgery, based on an innovative marker: circulating tumor DNA.

  Patients receive adjuvant chemotherapy every 2 weeks during 6 months: FOLFOX6m (5-FU, leucovorin and oxaliplatin).

Первичные конечные точки

• 3-year Disease-Free Survival in ctDNA positive patients [Срок оценки: 3-years]
