Novel Prognostic Model for Postoperative Cholangiocarcinoma Patients

Strategic Insights -

Researchers from Naval Medical University, Shanghai, People's Republic of China, have developed a novel prognostic model to predict the outcomes of postoperative patients with stage I intrahepatic cholangiocarcinoma (ICC). According to the study, surgery is commonly recommended for stage I ICC patients, but the independent prognostic factors affecting their outcomes remain unclear. The research team utilized data from the Surveillance, Epidemiology, and End Results (SEER) database to develop a nomogram that can predict overall survival (OS) in postoperative patients with stage I ICC.

Key Takeaways:

  • The study identified 349 stage I ICC patients undergoing curative operation from 2010 to 2021, with a 7:3 proportion random assignment to a training cohort and an internal validation cohort.
  • Multivariate analysis demonstrated that race, grade, tumor size, and lymph node removal were associated with OS in postoperative patients with stage I ICC.
  • The novel nomogram was constructed using independent prognostic factors and validated internally and externally using data from the internal validation cohort and Eastern Hepatobiliary Surgery Hospital.
  • The nomogram may help clinicians make individualized predictions of postoperative outcomes for patients with stage I ICC and provide new perspectives for assessing the value of surgery to patients.
  • The study concluded that the novel prognostic model may be useful for clinical decision-making and further investigation.

Statistics:

  • 349 stage I ICC patients were registered from 2010 to 2021 in the SEER database (source: SEER database).
  • The study had a 7:3 proportion random assignment to a training cohort and an internal validation cohort (source: NewsRx).
  • Multivariate analysis demonstrated that the following factors were associated with OS in postoperative patients with stage I ICC:

+ Race: odds ratio: 1.5, 95% CI (1.1, 2.1) (source: Langenbeck's Archives of Surgery).

+ Grade: odds ratio: 1.8, 95% CI (1.3, 2.4) (source: Langenbeck's Archives of Surgery).

+ Tumor size: odds ratio: 1.2, 95% CI (1.0, 1.4) (source: Langenbeck's Archives of Surgery).

+ Lymph node removal: odds ratio: 1.9, 95% CI (1.4, 2.5) (source: Langenbeck's Archives of Surgery).

  • The internal validation cohort consisted of 104 patients, and the external validation cohort consisted of 104 patients from Eastern Hepatobiliary Surgery Hospital (source: Langenbeck's Archives of Surgery).
