Objectives
Narrative objectives1
This study will evaluate the clinical utility of performing sequential cancer gene panel testing by analyzing cancer-related genomic alterations-such as base substitutions, insertions/deletions, amplifications, and fusions-using the Guardant360 CDx cancer gene panel (Guardant360) before first-line chemotherapy and after confirmation of disease progression in patients with metastatic colorectal cancer who have not received systemic chemotherapy. The study will determine the proportion of patients with actionable genomic alterations and the proportion in whom such actionable gene alterations change over time.

Assessment
Primary outcomes
The proportion of subjects who showed changes in actionable gene alterations between the first and second gene panel tests, where actionable gene alterations were defined as those classified as therapeutic level 1, 2, or R1 by OncoKB (excluding VUS and synonymous variants)
Key secondary outcomes
･Proportion of subjects for whom treatment was recommended by the Expert Panel (at the 1st and 2nd tests) and the changes observed.
･Proportion of subjects harboring actionable gene alterations (at the 1st and 2nd tests).
･Proportion of subjects who received the Expert Panel-recommended treatment (at the 1st and 2nd tests) and the changes observed.
･Best overall response and progression-free survival (PFS) for the Expert Panel-recommended treatments.
･Proportion of subjects to whom Expert Panel results were explained via telemedicine (restricted to applicable institutions).
･Overall survival (OS).

Key inclusion criteria
(1) Patients with histologically confirmed colorectal cancer (adenocarcinoma).
(2) Patients with unresectable colorectal cancer.
(3) Patients who are scheduled to receive systemic chemotherapy.
(4) Patients with no prior systemic chemotherapy for the current colorectal cancer (however, recurrence occurring >=24 weeks [168 days] after the last dose of perioperative chemotherapy is eligible).
(5) Patients with an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-1.
(6) Patients aged 18 years or older at the time of informed consent.
(7) Patients expected to survive for at least 3 months.
(8) Patients who have received adequate explanation regarding the study and have provided written informed consent.
Key exclusion criteria
(1) Patients with active double cancers*, including those occurring in the colon.
*Double cancer is defined as synchronous cancers or metachronous cancers with a disease-free interval of <=2 years. Lesions equivalent to carcinoma in situ or intramucosal carcinoma that are curable with local therapy are not considered active double cancers.
(2) Patients in whom blood collection is difficult.
(3) Patients with psychiatric disorders or psychiatric symptoms that interfere with daily life and are judged to make participation in the study difficult.
(4) Any other patients whom the principal investigator or a sub-investigator judges to be unsuitable for safe participation in the study.
