A Prospective Cohort Study of Advanced Colorectal Cancer Treated With Oxaliplatin and Irinotecan.
Study Details
Study Description
Brief Summary
The goal of this prospective observational study is to learn about the treatment decisions in advanced colorectal cancer treated with oxaliplatin and irinotecan. The main questions:1. learn about the efficacy and safety of immunotherapy or targeted drugs or other chemotherapy for patients treated with oxaliplatin and irinotecan（non-retreatment/rechallenge group，NR group）. 2. learn about the efficacy and safety of oxaliplatin or irinotecan for patients treated with oxaliplatin and irinotecan (retreatment/rechallenge group, RT/RC group). 3. compare the efficacy and safety of various treatment regimens for patients treated with oxaliplatin and irinotecan. This study will only collect the clinical data of patients, without any intervention, in the treatment services. All participants will be provided written informed consent as per the Declaration of Helsinki principles.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| NR group (Non-retreatment/rechallenge group) participants who receive immunotherapy or targeted drugs or other chemotherapy beyond treated with oxaliplatin and irinotecan |
|
| RT group (Retreatment group) participants retreated oxaliplatin or irinotecan who were treated with oxaliplatin and irinotecan and progressed after 3 months of oxaliplatin or irinotecan discontinuation. |
|
| RC group (Rechallenge group) participants rechallenging oxaliplatin or irinotecan who were treated with oxaliplatin and irinotecan and progressed within 3 months of oxaliplatin or irinotecan discontinuation. |
Outcome Measures
Primary Outcome Measures
- Progression free survival, PFS [Up to 12 months]
PFS was calculated as the time from the date of treatment initiation to the date of disease progression or the last follow-up
- Overall Survival, OS [Up to 24 months]
OS was calculated as the time from the date of treatment initiation to the date of any cause of death, or the last follow-up.
Secondary Outcome Measures
- Objective response rate ，ORR [Up to 12 months]
The ORR was defined as the percentage of patients performing a complete response (CR) or a partial response (PR) according to RECIST V1.1.
- Disease Control Rate，DCR [Up to 12 months]
The ORR was defined as the percentage of patients performing a complete response (CR) or a partial response (PR) or a stable disease (SD) according to RECIST V1.1.
- Quality of life score [Up to 24 months]
evaluated according to EORTC QLQ-C30 V3.0
- Comprehensive score of economic burden [Up to 24 months]
evaluated according to COST-PROM
- Adverse events, AEs [Up to 24 months]
evaluated by NCI-CTC AE V5.0
