Study population: This is a retrospective, cross-sectional, multicenter observational study. The study population includes patients pathologically diagnosed with colorectal adenocarcinoma between January 1, 2016 and December 31, 2020 from medical centers in Xinjiang Uygur Autonomous Region and Shandong Province. Patients aged 18 years and above with complete clinical, pathological, treatment and follow-up data will be included. The study aims to analyze the regional epidemiological characteristics and prognostic factors of colorectal cancer.

About this study

Official title: Identification of Regional Epidemiological Characteristics and Key Prognostic Factors of Colorectal Cancer in Xinjiang and Shandong: A Multicenter, Retrospective Study

This is a multicenter, retrospective, cross-sectional observational study aiming to investigate the 5-year overall survival (OS) rate of colorectal cancer (CRC) patients in Xinjiang and Shandong provinces of China. A total of no less than 500 pathologically confirmed CRC patients from 7 medical centers during January 1, 2016 to December 31, 2020 will be enrolled. We will collect and analyze the demographic characteristics, lifestyle, clinical pathological features, treatment patterns and survival prognosis data of patients, explore the regional differences of CRC and its key prognostic factors, and construct a CRC prognostic prediction model. The results will provide theoretical guidance for clinical practice and the formulation of public health policies.

Read the detailed description

Colorectal cancer is one of the most common malignant tumors with obvious regional distribution differences in incidence and prognosis. There are significant differences in economic development, lifestyle, dietary structure and medical resource allocation between Xinjiang (western China) and Shandong (eastern China), which may lead to different epidemiological characteristics and prognosis of CRC patients in the two regions. This study will enroll CRC patients from 7 multicenters in Xinjiang and Shandong, collect retrospective clinical data including demographic information, pathological features, treatment modes and follow-up records, use statistical methods such as Kaplan-Meier survival analysis and Cox proportional hazard regression model to analyze the 5-year OS rate and prognostic factors of patients in the two regions, compare the regional differences of CRC, and construct a Nomogram prognostic prediction model. The study will provide a scientific basis for the personalized treatment and regional public health prevention and control of CRC.

  • Retrospective Data CollectionOther

    Also called Retrospective Clinical Data Collection and Analysis for Colorectal Cancer

    Retrospective collection, collation and statistical analysis of de-identified clinical, pathological, treatment and follow-up data of pathologically confirmed colorectal cancer patients from 7 medical centers in Xinjiang and Shandong provinces from January 1, 2016 to December 31, 2020. The collected data includes demographic characteristics, lifestyle, tumor clinical pathological features, treatment patterns and 5-year overall survival status, for the purpose of analyzing regional epidemiological characteristics and key prognostic factors of colorectal cancer.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer, run by Qianfoshan Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

5-year Overall Survival (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Apr 2026.
