About this study

In some colon cancer patients, although adhesions between the tumor tissue and surrounding organs are found during surgery, postoperative pathology confirms that the tumor has not directly invaded the adhered organs; instead, the adhesions are caused by tumor-associated inflammation. This condition is defined as tumor-associated inflammatory adhesion.

Currently, the impact of tumor-associated inflammatory adhesion on patient prognosis is still unclear. This study aims to explore the impact of tumor-associated inflammatory adhesion on the prognosis of colon cancer patients through the Surveillance, Epidemiology, and End Results (SEER) and Chinese multi-center databases.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • The patient was pathologically diagnosed as colon adenocarcinoma by endoscopic biopsy before operation.
  • All patients were considered to have tumors invading adjacent organs during surgery
  • All patients underwent radical surgery.

Exclusion criteria

  • Patients with distant metastasis, recurrent colon cancer and pT4b CRC were excluded.

Treatment and study plan

This was a retrospective study and no patient intervention was performed.

Other

This was a retrospective study and no patient intervention was performed.

Primary outcomes

  1. Overall survival time (OS)

    Time frame: up to 10 years

    OS, defined as the time from the first diagnosis to death from any cause or the last follow-up for surviving patients

  2. Cancer-specific survival time (CSS)

    Time frame: up to 10 years

    CSS refers to the duration from diagnosis of a tumor until the patient succumbs to the tumor, excluding deaths from other causes.

  3. Recurrence free survival time (RFS)

    Time frame: up to 10 years

    RFS is the time from the time a patient achieved R0 resection after surgery to the time of recurrence or the end of follow-up.
