Adjuvant Chemotherapy Combined With Targeted Therapy or Not in the T3-4N2 Colorectal Cancer Patients
May 22, 2023 updated by: Yanxin Luo,MD, Sixth Affiliated Hospital, Sun Yat-sen University
Adjuvant Chemotherapy Combined With Targeted Therapy Versus Adjuvant Chemotherapy Alone in the Treatment of Stage T3-4N2 Colorectal Cancer:A Multicenter, Randomized, Phase III Clinical Trail
The goal of this clinical trial] is to compare in resectable stage T3-4N2 colorectal cancer.
The main question it aims to answer is: whether the use of targeted therapy in combination with adjuvant chemotherapy is associated with improved disease-free survival (DFS) compared to adjuvant chemotherapy alone.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Combining targeted therapy group
Adjuvant chemotherapy with targeted therapy
|
Chemotherapy regimens recommended include oxaliplatin-based CapeOx or FOLFOX regimens, or single-agent 5-FU/LV, capecitabine, or combination with targeted therapy.
Other Names:
Targeted therapy regimens are recommended based on gene testing results.
For colorectal cancer patients with KRAS/NRAS/BRAF gene mutations, it is recommended to use Bevacizumab in combination with chemotherapy.
For right-sided colon cancer patients with wild-type KRAS/NRAS/BRAF genes, it is recommended to use Bevacizumab.
For left-sided colon and rectal cancer patients with wild-type KRAS/NRAS/BRAF genes, it is recommended to use Cetuximab.When using targeted therapy in combination with chemotherapy, the treatment course should be synchronized with chemotherapy (Bev 5mg/kg iv d1 or Cet 500mg/m2 iv d1).

When evaluating the safety and tolerability of adjuvant therapy, researchers typically assess adverse events (AEs) based on their incidence and severity, and then grade them according to the NCI CTCAE version 5.0.
NCI CTCAE 5.0 categorizes AEs into 5 grades based on severity, including grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (life-threatening), and grade 5 (death).
