Chronic Inflammation, Plasma Proteins Signature, Survival Outcomes and Clinical Response, in Patients Receiving Bevacizumab Combined With Oxaliplatin-based Chemotherapy (Bev/OX) or Bevacizumab Combined With Irinotecan-based Chemotherapy (Bev/IRI)

November 16, 2025 updated by: Second Affiliated Hospital of Nanchang University

The Role of Chronic Inflammation in Modulating Targeted Therapy Efficacy and Predicting Treatment Outcomes in Metastatic Colorectal Cancer

Cancer-derived inflammation attenuates the efficacy of adjuvant chemotherapy (CT) in postoperative or metastatic colorectal cancer (mCRC). However, its role in mCRC patients receiving first-line Bevacizumab combined with chemotherapy (Bev/CT) remains unknown. In this prospective observational study, three Bev/CT regimen cohorts (discovery cohort,n=249; Internal validation cohort: n=115; external validation cohort: n=159) and one CT regimen cohort (n=175) were enrolled. Overall survival served as the primary endpoint; clinical response and progression-free survival were secondary endpoints evaluated during follow-up. Investigators used the serum inflammation ratios to evaluate the association between systemic inflammation and clinical outcomes in Bev/CT- and CT-treated mCRC. Combined analysis of 12 cytokines (flow cytometry) and 92 immuno-oncology proteins (Olink) revealed Bev resistance mechanisms and prognosis-predictive biomarkers in Bev/CT treated patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

In this study, all enrolled patients received first-line CT or Bev/CT based on the decisions made by both patients and clinicians. The treatment regimens included: (1) oxaliplatin-based CT (FOLFOX/XELOX, OX), (2) irinotecan-based CT (FOLFIRI/ XELIRI, IRI), (3) Bev combined with oxaliplatin-based CT (Bev/OX), and (4) Bev combined with irinotecan-based CT (Bev/IRI). All the patients underwent at least two cycles of Bev/CT until they either withdrew from the disease, experienced disease progression, or encountered intolerable toxic effects.

Description

Inclusion Criteria:

  • Clinical diagnosis of mCRC;
  • Aged over 18 years;
  • Must be able to receive the further treatment in the hospital.

Exclusion Criteria:

  • More than two types of malignancies;
  • Bacterial or virus infection within one month before diagnosis;
  • Taken anti-inflammatory drugs or other forms of chemotherapy before their diagnosis;
  • participants whose follow-up was interrupted three months ago without reaching any endpoint.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall survival (OS)
Time Frame: From January 2018 to December 2024
OS is the time from initial diagnosis to death, or the last follow-up
From January 2018 to December 2024

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression-free survival (PFS)
Time Frame: Form January 2018 to December 2024
PFS is the time from initial diagnosis to disease progression.
Form January 2018 to December 2024

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2018

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
December 30, 2024

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
